    Arthroscopic rotator cuff surgery is one of the most commonly performed orthopedic surgical procedures. We conducted a study to calculate the direct cost of arthroscopic repair of rotator cuff tears confirmed by magnetic resonance imaging. Twenty-eight shoulders in 26 patients (mean age, 54.5 years) underwent primary rotator cuff repair by a single fellowship-trained arthroscopic surgeon in the outpatient surgery center of a major academic medical center. All patients had interscalene blocks placed while in the preoperative holding area. Direct costs of this cycle of care were calculated using the time-driven activity-based costing algorithm. Mean time in operating room was 148 minutes; mean time in recovery was 105 minutes. Calculated surgical cost for this process cycle was $5904.21. Among material costs, suture anchor costs were the main cost driver. Preoperative bloodwork was obtained in 23 cases, adding a mean cost of $111.04. Our findings provide important preliminary information regarding the direct economic costs of rotator cuff surgery and may be useful to hospitals and surgery centers negotiating procedural reimbursement for the increased cost of repairing complex tears.

    Full Text Available Purpose: Arthroscopic transosseous (TO rotator cuff repair has recently emerged as a new option for surgical treatment of symptomatic rotator cuff tears. Limited data is available regarding outcomes using this technique. This study evaluated midterm clinical outcomes following a novel arthroscopic TO (anchorless rotator cuff repair technique. Materials and Methods: A consecutive series of 107 patients and 109 shoulders underwent arthroscopic TO (anchorless rotator cuff repair for a symptomatic full-thickness tear. Pre and postoperative range of motion (ROM was compared at an average of 11.8 months. Postoperative outcome scores were obtained at an average of 38.0 months. Statistical analysis was performed to compare pre and postoperative ROM data. Univariate analysis was performed using Student′s t-test to compare the effect of other clinical characteristics on final outcome. Results: Statistically significant improvements were noted in forward flexion, external rotation and internal rotation (P < 0.0001. Average postoperative subjective shoulder value was 93.7, simple shoulder test 11.6, and American Shoulder and Elbow Surgeons (ASES score 94.6. According to ASES scores, results for the 109 shoulders available for final follow-up were excellent in 95 (87.1%, good in 8 (7.3%, fair in 3 (2.8%, and poor in 3 (2.8%. There was no difference in ROM or outcome scores in patients who underwent a concomitant biceps procedure (tenodesis or tenotomy compared with those who did not. Furthermore, there was no significant difference in outcome between patients who underwent either biceps tenodesis or tenotomy. Age, history of "injury" preceding the onset of pain, tear size, number of TO tunnels required to perform the repair, and presence of fatty infiltration did not correlate with postoperative ROM or subjective outcome measures at final follow-up. Two complications and four failures were noted. Conclusions: Arthroscopic TO rotator cuff repair technique

    Objectives: An arthroscopic superior capsule reconstruction, in which the fascia lata autograft attached medially to the superior glenoid and laterally to the greater tuberosity, restores shoulder stability and muscle balance in patients with irreparable rotator cuff tears; consequently, it improves shoulder function specifically deltoid muscle function and relieves pain. We assessed the clinical outcome of arthroscopic superior capsule reconstruction (Figure 1) in 100 consecutive patients with irreparable rotator cuff tears. Specifically, we focused on the rates of return to sport and work. Methods: From 2007 to 2014, we performed arthroscopic superior capsule reconstruction on 107 consecutive patients (mean 66.7 years; range, 43 to 82) with irreparable rotator cuff tears that had failed conservative treatment. Seven patients were lost to follow-up because of other medical problems or reasons. In the remaining 100 patients there were 56 supraspinatus and infraspinatus tears; 39 supraspinatus, infraspinatus, and subscapularis tears; 3 supraspinatus, infraspinatus, teres minor, and subscapularis tears; and 2 supraspinatus, infraspinatus, and teres minor tears. Physical examination, radiography, and MRI were performed before surgery; at 3, 6, and 12 months after surgery; and yearly thereafter. Rates of return to sport and work were also investigated in those patients who had been employed (34 patients: 21 manual workers, 10 farmers, 1 butcher, 1 cook, and 1 athletic trainer) or played sport (26 patients: 6 golf, 4 table tennis, 4 swimming, 3 martial arts, 2 baseball, 2 yoga, 1 tennis, 1 badminton, 1 skiing, 1 mountain-climbing, and 1 ground golf) before injury. Results: The average preoperative American Shoulder and Elbow Surgeons (ASES) score was 31.6 points (range, 3.3 to 63.3 points) and the average Japanese Orthopaedic Association (JOA) score was 51.6 points (26.5 to 68.5 points). Average postoperative clinical outcome scores all improved significantly at final

    According to our previous clinical impression, we hypothesized that patients who had symptomatic rotator cuff tendon tear in a diamemter below 3 cm would benefit from arthroscopic subacromial decompression only, without the need for the repair of the thorn tendon. From 1998 to 2003, 160 patients (168 shoulders) had arthroscopic subacromial decompression for impingement syndrome with a torn rotator cuff without repairing the tear of the cuffs (120 males and 40 females). The average patient age...

    Arthroscopic rotator cuff repair (ARCR) can provide excellent clinical results for patients who fail to respond to conservative management of symptomatic rotator cuff tears. ARCR, however, can be associated with severe postoperative pain and discomfort that requires adequate analgesia. As ARCR continues to shift toward being performed as an outpatient procedure, it is incumbent on physicians and ambulatory surgical centers to provide appropriate pain relief with minimal side effects to ensure rapid recovery and safe discharge. Although intravenous and oral opioids are the cornerstone of pain management after orthopedic procedures, they are associated with drowsiness, nausea, vomiting, and increased length of hospital stay. As health care reimbursements continue to become more intimately focused on quality, patient satisfaction, and minimizing of complications, the need for adequate pain control with minimal complications will continue to be a principal focus for providers and institutions alike. We present a review of alternative modalities for pain relief after ARCR, including cryotherapy, intralesional anesthesia, nerve blockade, indwelling continuous nerve block catheters, and multimodal anesthesia. In choosing among these modalities, physicians should consider patient- and system-based factors to allow the efficient delivery of analgesia that optimizes recovery and improves patient satisfaction.

  9. The Burden of Craft in Arthroscopic Rotator Cuff Repair: Where Have We Been and Where We Are Going.

    The rather turbulent history of arthroscopic rotator cuff repair went through stages of innovation, conflict, disruption, assimilation, and transformation that might be anticipated when a new and advanced technology (arthroscopic cuff repair) displaces an entrenched but outdated discipline (open cuff repair). The transition from open to arthroscopic rotator cuff repair has been a major paradigm shift that has greatly benefited patients. However, this technical evolution/revolution has also imposed a higher "burden of craft" on the practitioners of arthroscopic rotator cuff repair. Technological advancements in surgery demand that surgeons accept this burden of craft and master the advanced technology for the benefit of their patients. This article outlines the author's involvement in the development of arthroscopic rotator cuff repair, and it also explores the surgeon's obligation to accept the burden of craft that is imposed by this discipline.

  11. The global percutaneous shuttling technique tip for arthroscopic rotator cuff repair

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available Most arthroscopic rotator cuff repairs utilize suture passing devices placed through arthro- scopic cannulas. These devices are limited by the size of the passing device where the suture is passed through the tendon. An alternative technique has been used in the senior author’s practice for the past ten years, where sutures are placed through the rotator cuff tendon using percutaneous passing devices. This technique, dubbed the global percutaneous shuttling technique of rotator cuff repair, affords the placement of sutures from nearly any angle and location in the shoulder, and has the potential advantage of larger suture bites through the tendon edge. These advantages may increase the area of tendon available to compress to the rotator cuff footprint and improve tendon healing and outcomes. The aim of this study is to describe the global percutaneous shuttling (GPS technique and report our results using this method. The GPS technique can be used for any full thickness rotator cuff tear and is particularly useful for massive cuff tears with poor tissue quality. We recently followed up 22 patients with an average follow up of 32 months to validate its usefulness. American Shoulder and Elbow Surgeons scores improved significantly from 37 preoperatively to 90 postoperatively (P<0.0001. This data supports the use of the GPS technique for arthroscopic rotator cuff repair. Further biomechanical studies are currently being performed to assess the improvements in tendon footprint area with this technique.

    Rotator cuff repair has been shown to have good long-term results. Unfortunately, a significant proportion of repairs still fail to heal. Many factors, both patient and surgeon related, can influence healing after repair. Older age, larger tear size, worse muscle quality, greater muscle-tendon unit retraction, smoking, osteoporosis, diabetes and hypercholesterolemia have all shown to negatively influence tendon healing. Surgeon related factors that can influence healing include repair constru...

  13. Impingement syndrome of the shoulder following double row suture anchor technique for arthroscopic rotator cuff repair: a case report

    2009-06-01

    Full Text Available Abstract Introduction Arthroscopic repair of the rotator cuff is a demanding surgery. Accurate placement of anchors is key to success. Case presentation A 38-year-old woman received arthroscopic repair of her rotator cuff using a double row suture anchor technique. Postoperatively, she developed impingement syndrome which resulted from vertical displacement of a suture anchor once the shoulder was mobilised. The anchor was removed eight weeks following initial surgery and the patient had an uneventful recovery. Conclusion Impingement syndrome following arthroscopic repair of the rotator cuffs using double row suture anchor has not been widely reported. This is the first such case where anchoring has resulted in impingement syndrome.

    Objective To compare the clinical outcomes following conservative treatment and arthroscopic repair in patients with a rotator cuff tear. Methods In this retrospective study, patients aged >50 years with a symptomatic rotator cuff tear were reviewed. The rotator cuff tendons were evaluated using ultrasonography, shoulder magnetic resonance imaging or MR arthrography, and the patients with either a high-grade partial-thickness or small-to-medium-sized (≤3 cm) full-thickness tear were included in this study. The primary outcome measures were a pain assessment score and range of motion (ROM) at 1-year follow-up. The secondary outcomes were the rate of tear progression or retear along with the rate of symptom aggravation after the treatments. Results A total of 357 patients were enrolled, including 183 patients that received conservative treatment and 174 patients who received an arthroscopic repair. The pain assessment score (p50 years old with a less than medium-sized rotator cuff tear in a 1-year follow-up period. Further study is warranted to find the optimal combination of conservative treatment for a symptomatic rotator cuff tear. PMID:27152275

    We assessed the diagnostic performance of magnetic resonance (MR) arthrography in the diagnosis of articular-sided partial-thickness and full-thickness rotator cuff tears in a large symptomatic population. MR arthrograms obtained in 275 patients including a study group of 139 patients with rotator cuff tears proved by arthroscopy and a control group of 136 patients with arthroscopically intact rotator cuff tendons were reviewed in random order. MR imaging was performed on a 1.0 T system (Magnetom Expert, Siemens). MR arthrograms were analyzed by two radiologists in consensus for articular-sided partial-thickness and full-thickness tears of the supraspinatus, infraspinatus, and subscapularis tendons. At arthroscopy, 197 rotator cuff tears were diagnosed, including 105 partial-thickness (93 supraspinatus, nine infraspinatus, three subscapularis) and 92 full-thickness (43 supraspinatus, 20 infraspinatus, 29 subscapularis) tendon tears. For full-thickness tears, sensitivity, specificity, and accuracy were 96%, 99%, and 98%, respectively, and for partial tears 80%, 97%, and 95%, respectively. False negative and positive assessments in the diagnosis of articular-sided partial-thickness tears were predominantly [78% (35/45)] observed with small articular-sided (Ellman grade1) tendon tears. MR arthrography is highly accurate in the diagnosis of full-thickness rotator cuff tears and is accurate in the diagnosis of articular-sided partial-thickness tears. Limitations in the diagnosis of partial-thickness tears are mainly restricted to small articular-sided tears (Ellman grade 1) due to difficulties in differentiation between fiber tearing, tendinitis, synovitic changes, and superficial fraying at tendon margins.

  18. Changes in the size of rotator cuff tear after arthroscopic subacromial decompression. Part 2. Evaluation with MRI

    International Nuclear Information System (INIS)

    Relationships between changes in the length and width of rotator cuff tears and symptoms after arthroscopic subacromial decompression (ASD) were investigated in a prospective study. MRI was performed before the operation and again 6 months and 2 years after the operation, and changes in the size of the rotator cuff tears were analyzed. At 2 years after ASD an increase in the length of the rotator cuff defect was seen in 7 shoulders (27%), and increase in width in 6 shoulders (23%). No worsening of pain or range of motion (ROM) accompanying the enlargement of the rotator cuff tears was seen. However, the increase in width of the rotator cuff tears resulted in a poorer Japanese Orthopaedic Association (JOA) score for function. (author)

    [Purpose] The effect of early rehabilitation protocols after arthroscopic rotator cuff repair is currently unknown. We examined short-term effects of early rehabilitation on functional outcomes and activities of daily living after arthroscopic rotator cuff repair. [Subject and Methods] An 82-year-old male fell during a walk, resulting in a supraspinatus tear. Arthroscopic rotator cuff repair was performed using a single-row technique. He wore an abduction brace for 6 weeks after surgery. [Results] From day 1 after surgery, passive range of motion exercises, including forward flexion and internal and external rotation were performed twice per day. Starting at 6 weeks after surgery, active range of motion exercises and muscle strengthening exercises were introduced gradually. At 6 weeks after surgery, his active forward flexion was 150°, UCLA shoulder rating scale score was 34 points, and Quick Disabilities of the Arm, Shoulder, and Hand questionnaire disability/symptom score was 36 points. At 20 weeks after surgery, his active forward flexion was 120°, UCLA shoulder rating scale score was 34 points, and Quick Disabilities of the Arm, Shoulder, and Hand questionnaire disability/symptom score was 0 points. [Conclusion] These protocols are recommended to physical therapists during rehabilitation for arthroscopic rotator cuff repair to support rapid reintegration into activities of daily living.

    Objective To evaluate whether the good and excellent functional results from arthroscopic repair of massive rotator cuff tears are maintained over the long term. Methods From the sample of the study conducted by our group in 2006, in which we evaluated the functional results from arthroscopic repair of massive rotator cuff tears, 35 patients were reassessed, 8 years after the first evaluation. The inclusion criteria were that these patients with massive rotator cuff tears operated by means of an arthroscopic technique, who participated in the previous study and achieved good or excellent outcomes according to the UCLA criteria. Patients whose results were not good or excellent in the first evaluation according to the UCLA criteria were excluded. Results Among the 35 patients reassessed, 91% of them continued to present good and excellent results (40% excellent and 51% good), while 3% presented fair results and 6% poor results. The time interval between the first and second evaluations was 8 years and the minimum length of follow-up since the immediate postoperative period was 9 years (range: 9–17 years), with an average of 11.4 years. Conclusion The good and excellent results from arthroscopic repair of massive rotator cuff tears were mostly maintained (91%), with the same level of function and satisfaction, even though 8 years had passed since the first assessment, with a follow-up period averaging 11.4 years.

    Objective To evaluate the clinical outcome of arthroscopic rotator cuff fixation and, when present, simultaneous repair of the Bankart lesion caused by traumatic dislocation; and to assess whether the size of the rotator cuff injury caused by traumatic dislocation has any influence on the postoperative clinical outcomes. Methods Thirty-three patients with traumatic shoulder dislocation and complete rotator cuff injury, with at least two years of follow up, were retrospectively evaluated. For analysis purposes, the patients were divided into groups: presence of fixed Bankart lesion or absence of this lesion, and rotator cuff lesions smaller than 3.0 cm (group A) or greater than or equal to 3.0 cm (group B). All the patients underwent arthroscopic repair of the lesions and were evaluated postoperatively by means of the UCLA (University of California at Los Angeles) score and strength measurements. Results The group with Bankart lesion repair had a postoperative UCLA score of 33.96, while the score of the group without Bankart lesion was 33.7, without statistical significance (p = 0.743). Group A had a postoperative UCLA score of 34.35 and group B, 33.15, without statistical significance (p = 0.416). Conclusion The functional outcomes of the patients who only presented complete rotator cuff tearing after traumatic shoulder dislocation, which underwent arthroscopic repair, were similar to the outcomes of those who presented an associated with a Bankart lesion that was corrected simultaneously with the rotator cuff injury. The extent of the original rotator cuff injury did not alter the functional results in the postoperative evaluation. PMID:27069884

    This is a consensus statement on rehabilitation developed by the American Society of Shoulder and Elbow Therapists. The purpose of this statement is to aid clinical decision making during the rehabilitation of patients after arthroscopic rotator cuff repair. The overarching philosophy of rehabilitation is centered on the principle of the gradual application of controlled stresses to the healing rotator cuff repair with consideration of rotator cuff tear size, tissue quality, and patient variables. This statement describes a rehabilitation framework that includes a 2-week period of strict immobilization and a staged introduction of protected, passive range of motion during weeks 2-6 postoperatively, followed by restoration of active range of motion, and then progressive strengthening beginning at postoperative week 12. When appropriate, rehabilitation continues with a functional progression for return to athletic or demanding work activities. This document represents the first consensus rehabilitation statement developed by a multidisciplinary society of international rehabilitation professionals specifically for the postoperative care of patients after arthroscopic rotator cuff repair.

    Objective To analyze the results from arthroscopic suturing of large and extensive rotator cuff injuries, according to the patient's degree of osteopenia. Method 138 patients who underwent arthroscopic suturing of large and extensive rotator cuff injuries between 2003 and 2011 were analyzed. Those operated from October 2008 onwards formed a prospective cohort, while the remainder formed a retrospective cohort. Also from October 2008 onwards, bone densitometry evaluation was requested at the time of the surgical treatment. For the patients operated before this date, densitometry examinations performed up to two years before or after the surgical treatment were investigated. The patients were divided into three groups. Those with osteoporosis formed group 1 (n = 16); those with osteopenia, group 2 (n = 33); and normal individuals, group 3 (n = 55). Results In analyzing the University of California at Los Angeles (UCLA) scores of group 3 and comparing them with group 2, no statistically significant difference was seen (p = 0.070). Analysis on group 3 in comparison with group 1 showed a statistically significant difference (p = 0.027). Conclusion The results from arthroscopic suturing of large and extensive rotator cuff injuries seem to be influenced by the patient's bone mineral density, as assessed using bone densitometry.

    Aim: To evaluate mid-term outcome in patients who underwent arthroscopic subacromial decompression (ASD) for shoulder impingement syndrome with intact and partially torn rotator cuffs. Materials and Methods: A total of 80 consecutive patients (83 shoulders) who underwent ASD for impingement syndrome between 2003 and 2006 were analyzed. Mean age was 57.1 years. Patients’ self-reported Oxford Shoulder Score (OSS) for pain was collected prospectively and was used as an instrument to measure surgical outcome. Results: The mean initial and final OSS for patients with an intact rotator cuff was 26.1 and 40.3, respectively, at a mean follow up of 71.9 months (nearly 7 years). The mean initial and final OSS for patients with a partially torn articular sided tear was 22.6 and 41.9, respectively, at mean follow up of 70.7 months. Both groups showed significant sustained improvement (P < 0.0001). The mean improvement of OSS following ASD was statistically greater (P < 0.03) for partially torn rotator cuff group (19.3 points) as compared to those with normal rotator cuff (14.2 points). Conclusion: Patients with dual pathology (partial rotator cuff tear and impingement) appreciated a significantly greater improvement following ASD compared to those with impingement alone. Both groups of patients had a similar final outcome at a mid-term follow up. Level of Evidence: IV, retrospective study on consecutive series of patients. PMID:23204763

    Objective: To comparatively analyze the results from arthroscopic rotator cuff suture between smoking and non-smoking patients. Methods: A group of 286 patients who underwent arthroscopic suturing of primary rotator cuff injuries between June 12, 2002, and May 14, 2008, was analyzed. The patients included in the study were evaluated using the UCLA scale, with a minimum follow-up of 12 months and average of 56.52 months. The variables studied were age, sex, side operated, dominance, profile of cigarette use and UCLA index. Results: This study evaluated a total of 205 patients. Mean age (p = 0.289) and sex (p = 0.124) were analyzed statistically between the smoking and non-smoking patients and the two groups were considered to be similar. The average UCLA score for the non-smoking patients (143) was 34 (32 to 35). The average UCLA score for the smoking patients (51) was 33 (29 to 35). There was no statistically significant difference in UCLA score (p = 0.123) between the smoking and non-smoking patients. For the purposes of statistical analysis, we grouped the small and medium tears (107) and compared these with the large and extensive tears (80), between smokers and non-smokers. There was no statistically significant difference using the Mann-Whitney test regarding the small and medium tears (p = 818). There was a statistically significant difference using the Mann-Whitney test regarding the large and extended tears, between the smoking and non-smoking patients, such that the non-smokers showed better UCLA scores (p = 0.038). Conclusion: The results from arthroscopic suturing of large and extensive rotator cuff injuries are inferior among smoking patients. PMID:27027006

    Full Text Available Abstract Background Arthroscopic rotator cuff repair has become popular in the last few years because it avoids large skin incisions and deltoid detachment and dysfunction. Earlier arthroscopic single-row (SR repair methods achieved only partial restoration of the original footprint of the tendons of the rotator cuff, while double-row (DR repair methods presented many biomechanical advantages and higher rates of tendon-to-bone healing. However, DR repair failed to demonstrate better clinical results than SR repair in clinical trials. MR imaging at 3 Tesla, especially with intra-articular contrast medium (MRA, showed a better diagnostic performance than 1.5 Tesla in the musculoskeletal setting. The objective of this study was to retrospectively evaluate the clinical and 3 Tesla MRA results in two groups of patients operated on for a medium-sized full-thickness rotator cuff tear with two different techniques. Methods The first group consisted of 20 patients operated on with the SR technique; the second group consisted of 20 patients operated on with the DR technique. All patients were evaluated at a minimum of 3 years after surgery. The primary end point was the re-tear rate at 3 Tesla MRA. The secondary end points were the Constant-Murley Scale (CMS, the Simple Shoulder Test (SST scores, surgical time and implant expense. Results The mean follow-up was 40 months in the SR group and 38.9 months in the DR group. The mean postoperative CMS was 70 in the SR group and 68 in the DR group. The mean SST score was 9.4 in the SR group and 10.1 in the DR group. The re-tear rate was 60% in the SR group and 25% in the DR group. Leakage of the contrast medium was observed in all patients. Conclusions To the best of our knowledge, this is the first report on 3 Tesla MRA in the evaluation of two different techniques of rotator cuff repair. DR repair resulted in a statistically significant lower re-tear rate, with longer surgical time and higher implant

    Full Text Available Background: The transosseous-equivalent cross bridge double row (TESBDR rotator cuff (RC repair technique has been developed to optimize healing biology at a repaired RC tendon insertion. It has been shown in the laboratory to improve pressurized contact area and mean foot print pressure when compared with a double row anchor technique. Pressure has been shown to influence healing between tendon and bone, and the tendon compression vector provided by the transosseous-equivalent suture bridges may enhance healing. The purpose was to prospectively evaluate the outcomes of arthroscopic TESBDR RC repair. Methods: Single center prospective case series study. Sixty-nine patients were selected to undergo arthroscopic TESBDR RC repair and were included in the current study. Primary outcome measures included the Oxford Shoulder Score (OSS, the University of California, Los Angeles (UCLA score, the Constant-Murley (CM Score and Range of motion (ROM. Secondary outcome measures included a Visual Analogue Scale (VAS for pain, another VAS for patient satisfaction from the operative procedure, EuroQoL 5-Dimensions Questionnaire (EQ-5D for quality of life assessment. Results: At 24 months post-operative, average OSS score was 44, average UCLA score was 31, average CM score was 88, average forward flexion was 145°, average internal rotation was 35°, average external rotation was 79°, average abduction was 150°, average EQ-5D score was 0.73, average VAS for pain was 2.3, and average VAS for patient satisfaction was 9.2. Conclusion: Arthroscopic TESBDR RC repair is a procedure with good post-operative functional outcome and low re-tear rate based on a short term follow-up.

    Full Text Available OBJECTIVES: To evaluate the results from arthroscopic surgical treatment of rotator cuff injuries in patients aged 65 years and over.METHODS: Between 1998 and 2009, 168 patients underwent operations. Five cases were excluded. The remaining 163 patients were stratified according to their age group: 65-69 years (49.1%, 70-74 (26.4% and 75 years and over (24.5%. Their mean age was 71 years (range: 65-83. There were 63 male patients (38.7%. The mean length of time with pain, from the onset of symptoms to the surgery, was 23 months (range: 2 days to 240 months. Sixty-two patients (38% reported histories of trauma and 26 (16% reported that their pain worsened through exertion.RESULTS: From the UCLA criteria, 80.4% of the results were excellent, 16% good, 1.8% fair and 1.8% poor. Complications occurred in 11%. The final clinical result did not show any correlation with age progression, injury size or tendons affected. However, there was a significant association (p < 0.001 between the presence of trauma and larger injuries. The length of time between the onset of symptoms and the surgical procedure had a significant relationship (p < 0.027 with the postoperative results: the longer this time was, the worse the results were.CONCLUSION: Arthroscopic treatment of rotator cuff injuries in patients aged 65 years and over presented excellent and good results in 96.4% of the cases, according to the UCLA assessment, with a low complication rate. Advanced age did not show any influence on the postoperative clinical evolution, but the earlier the surgical treatment was instituted, the better the results were.

    Full Text Available Rotator cuff tear has been a known entity for orthopaedic surgeons for more than two hundred years. Although the exact pathogenesis is controversial, a combination of intrinsic factors proposed by Codman and extrinsic factors theorized by Neer is likely responsible for most rotator cuff tears. Magnetic resonance imaging remains the gold standard for the diagnosis of rotator cuff tears, but the emergence of ultrasound has revolutionized the diagnostic capability. Even though mini-open rotator cuff repair is still commonly performed, and results are comparable to arthroscopic repair, all-arthroscopic repair of rotator cuff tear is now fast becoming a standard care for rotator cuff repair. Appropriate knowledge of pathology and healing pattern of cuff, strong and biological repair techniques, better suture anchors, and gradual rehabilitation of postcuff repair have led to good to excellent outcome after repair. As the healing of degenerative cuff tear remains unpredictable, the role of biological agents such as platelet-rich plasma and stem cells for postcuff repair augmentation is still under evaluation. The role of scaffolds in massive cuff tear is also being probed.

  3. PARot – assessing platelet-rich plasma plus arthroscopic subacromial decompression in the treatment of rotator cuff tendinopathy: study protocol for a randomized controlled trial

    Science.gov (United States)

    2013-01-01

    Background Platelet-rich plasma (PRP) is an autologous platelet concentrate. It is prepared by separating the platelet fraction of whole blood from patients and mixing it with an agent to activate the platelets. In a clinical setting, PRP may be reapplied to the patient to improve and hasten the healing of tissue. The therapeutic effect is based on the presence of growth factors stored in the platelets. Current evidence in orthopedics shows that PRP applications can be used to accelerate bone and soft tissue regeneration following tendon injuries and arthroplasty. Outcomes include decreased inflammation, reduced blood loss and post-treatment pain relief. Recent shoulder research indicates there is poor vascularization present in the area around tendinopathies and this possibly prevents full healing capacity post surgery (Am J Sports Med36(6):1171–1178, 2008). Although it is becoming popular in other areas of orthopedics there is little evidence regarding the use of PRP for shoulder pathologies. The application of PRP may help to revascularize the area and consequently promote tendon healing. Such evidence highlights an opportunity to explore the efficacy of PRP use during arthroscopic shoulder surgery for rotator cuff pathologies. Methods/Design PARot is a single center, blinded superiority-type randomized controlled trial assessing the clinical outcomes of PRP applications in patients who undergo shoulder surgery for rotator cuff disease. Patients will be randomized to one of the following treatment groups: arthroscopic subacromial decompression surgery or arthroscopic subacromial decompression surgery with application of PRP. The study will run for 3 years and aims to randomize 40 patients. Recruitment will be for 24 months with final follow-up at 1 year post surgery. The third year will also involve collation and analysis of the data. This study will be funded through the NIHR Biomedical Research Unit at the Oxford University Hospitals NHS Trust. Trial

    BACKGROUND:There are controversies about the efficacy of al-arthroscopic rotator cuff repairversus mini-open for the treatment of rotator cuff injury. OBJECTIVE:To evaluate the efficacy of al-arthroscopic rotator cuff repairversusmini-open for the treatment of rotator cuff injury by conducting a meta-analysis. METHODS:A computer-based online search was conducted in PubMed, Embase, Cochrane Library and CBM databases from January 1966 to November 2015 to screen the relevant articles usingthe key words of“rotator cuff, arthroscopy, mini-open”. Meta-analysis was performed using Revman5.3 software. RESULTS AND CONCLUSION:A total of 11 studies, including 6randomized controled trialsand 5 cohort studies,were selected. The meta-analysis results showed that there were no significant differences in the function and strength of the shoulder joint, pain, motor range, recurrence of rotator cuff avulsion, the incidence rate of ankylosis between both two groups (P> 0.05). These results suggest that the efficacy of al-arthroscopic rotator cuff repair does not differ from those of mini-open for the treatment of rotator cuff injury. However arthroscopic rotator cuff repair induces less soft tissue injury and early incision pain, but better function recovery.%背景:对于全关节镜及小切口两种修复式的疗效比较,国内外尚有许多争议。  目的:对全关节镜及小切口两种方法治疗肩袖损伤的疗效进行荟萃分析。  方法:以“肩袖”、“关节镜”、“小切口”为检索词,计算机检索1966年1月至2015年11月PubMed, Embase,Cochrane图书馆和CBM,搜集所有的有关论研究。筛选并提取数据,采用Revman5.3软件进行荟萃分析。  结果与结论:共纳入11例研究,其中6例随机对照研究,5例队列研究,荟萃分析显示这两组肩关节功能、疼痛、活动范围、肩袖再撕裂率、关节僵硬发生率以及肩关节力量差异均无显著性意义(P>0

  6. Rotator cuff pathology

    International Nuclear Information System (INIS)

    Fifteen volunteers and 73 patients with suspected rotator cuff lesions were examined at 0.5 T with T2*-weighted gradient-echo (GE) MR imaging (700/33/30 degrees) (oblique coronal and sagittal 3 mm thick, surface coil). Results were compared with those of arthrography (all cases), T1-weighted GE imaging (400/20/90 degrees) (35 cases), surgery (28 cases), and T2-weighted spin-echo (SE) images (2,000/60-120) (17 cases). GE images demonstrated all tears (complete, 32, partial, 12) and was superior to arthrography in determining site and size and in displaying muscles (critical point in surgical planning). In 20 cases without tears on arthrography, GE imaging demonstrated five cases of tendinitis, five cases of bursitis, and six probable intratendinous or superficial partial tears. T2*-weighted GE imaging was superior to T2-weighted SE and T1-weighted GE imaging, with higher fluid contrast and a low fat signal. Therefore, it might replace arthrography in the diagnosis and surgical approach to this pathology

    The impingement syndrome and tendinopathy of the rotator cuff are the most common causes (complaints) of pain and disability of the shoulder. The aim of this study is to evaluate the efficacy of a specific rehabilitative protocol, integrated with the administration of a nutritional supplement, in the conservative rehabilitative treatment, as well as in post-surgery, of patients with lesions of the rotator cuff. Two groups with syndrome of the rotator cuff were formed to follow different therapeutic courses, in relation to the choice of each subject to undergo the conservative treatment (Arm A) or the surgical one (Arm B). In Arm A the study included the association of therapy with ESWT (shock waves) with the proprioceptive Multi Joint System, for rehabilitating joint movement and muscle strength of the shoulder, and a specific nutritional supplement to reduce the pain and conserve the cartilage tissue. Between February 2009 and June 2009, we enrolled 30 subjects (randomized into three homogenous groups A1, A2, A3), average age 45±10 years, with rotator cuff syndrome with calcification of the shoulder, diagnosed through clinical examination and investigative instruments (X-ray, echography or NMR). In Arm B, from September 2009 to January 2010, we enrolled 50 patients (randomized into two groups, B1 and B2), 24 male (average age 58.4: min 28 and max 78) and 26 females (average age 59.5: min 30 and max 80), who had undergone rotator cuff operations and acromionplasty for non-massive lesions without important gleno-humeral instability, with either open or arthroscopic procedures. The analysis of the results of Arm A highlights that in terms of reducing pain the main benefits were found in Group A1 where the supplement was given. From the analysis of the data of Arm B, in both groups an improvement of the first 4 items evaluated was evident. In Group B1, 84 percent of the patients declared to be satisfied and improved and 16 percent were dissatisfied; in Group B2

    To determine relationships between different types of rotator cuff tears and radiographic abnormalities. The shoulder radiographs of 104 patients with an arthroscopically proven rotator cuff tear were compared with similar radiographs of 54 age-matched controls with intact cuffs. Two radiologists independently interpreted all radiographs for; cortical thickening with subcortical sclerosis, subcortical cysts, osteophytes in the humeral greater tuberosity, humeral migration, degenerations of the acromioclavicular and glenohumeral joints, and subacromial spurs. Statistical analysis was performed to determine relationships between each type of rotator cuff tears and radiographic abnormalities. Inter-observer agreements with respect to radiographic findings were analyzed. Humeral migration and degenerative change of the greater tuberosity, including sclerosis, subcortical cysts, and osteophytes, were more associated with full-thickness tears (p < 0.01). Subacromial spurs were more common for full-thickness and bursal-sided tears (p < 0.01). No association was found between degeneration of the acromioclavicular or glenohumeral joint and the presence of a cuff tear. Different types of rotator cuff tears are associated with different radiographic abnormalities.

    Full Text Available Abstract Background Major shoulder surgery often results in severe post-operative pain and a variety of interventions have been developed in an attempt to address this. The continuous slow infusion of a local anaesthetic directly into the operative site has recently gained popularity but it is expensive and as yet there is little conclusive evidence that it provides additional benefits over other methods of post-operative pain management. Methods/Design This will be a randomised, placebo-controlled trial involving 158 participants. Following diagnostic arthroscopy, all participants will undergo arthroscopic subacromial decompression with or without rotator cuff repair, all operations performed by a single surgeon. Participants, the surgeon, nurses caring for the patients and outcome assessors will be blinded to treatment allocation. All participants will receive a pre-incision bolus injection of 20 mls of ropivacaine 1% into the shoulder and an intra-operative intravenous bolus of parecoxib 40 mg. Using concealed allocation participants will be randomly assigned to active treatment (local anaesthetic ropivacaine 0.75% or placebo (normal saline administered continuously into the subacromial space by an elastomeric pump at 5 mls per hour post-operatively. Patient controlled opioid analgesia and oral analgesics will be available for breakthrough pain. Outcome assessment will be at 15, 30 and 60 minutes, 2, 4, 8, 12, 18 and 24 hours, and 2 or 4 months for decompression or decompression plus repair respectively. The primary end point will be average pain at rest over the first 12-hour post-operative period on a verbal analogue pain score. Secondary end points will be average pain at rest over the second 12-hour post-operative period, maximal pain at rest over the first and second 12-hour periods, amount of rescue medication used, length of inpatient stay and incidence of post-operative adhesive capsulitis. Discussion The results of this trial will

    Background: Various tenodesis methods are being used for long head of the biceps tendon lesions. However, there is no consensus on the most appropriate surgical method. Hypothesis: There are significant differences in incidence of cosmetic deformity and persistent bicipital pain between open subpectoral and arthroscopic intracuff tenodesis groups. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 72 patients who underwent biceps tenodesis and rotator cuff repair between January 2009 and May 2014 and who were followed for at least 1 year. Open subpectoral tenodesis was performed in 39 patients (group A), and arthroscopic intracuff tenodesis was performed in 33 patients (group B). Results: In group A, the mean visual analog scale (VAS) score for pain during motion and mean University of California, Los Angeles (UCLA) and Constant scores significantly improved from 4.6, 18.6, and 64.5 preoperatively to 1.9, 30.5, and 86.5 at last follow-up, respectively (P < .001 for all). In group B, these scores significantly improved from 5.1, 17.6, and 62.9 preoperatively to 1.8, 31.5, and 85.9 at last follow-up, respectively (P < .001 for all). Popeye deformity was noted in 2 (5.2%) patients from group A and 5 (15.6%) patients from group B (P = .231). Additionally, persistent bicipital tenderness was noted in 1 (2.6%) patient from group A and 8 (24.2%) patients from group B (P = .012). Conclusion: Both open subpectoral tenodesis and arthroscopic intracuff tenodesis show good clinical outcomes for long head of the biceps tendon lesions. However, open subpectoral tenodesis may be more appropriate, considering the low incidence of Popeye deformity and tenderness. PMID:27231699

  6. Calcific Tendonitis of the Rotator Cuff: An Unusual Case

    Full Text Available Few case reports have described the surgical treatment of calcifying tendonitis of the subscapularis tendon. We present a case of symptomatic diffuse calcifying tendonitis involving the subscapularis and infraspinatus insertions that was difficult to detect arthroscopically. The patient was treated with arthroscopic incision of the tendinous insertions thorough removal of the calcific deposits and subsequent repair using a suture-anchor technique. Two years after the surgical procedure, the patient was completely pain-free and attained full range of motion. Radiographic evaluation performed 2 years after the procedure revealed no calcific deposits. We conclude that the combination of incision of the subscapularis and infraspinatus insertions, complete removal of the calcific deposits, and subsequent suture-anchor repair in an all-arthroscopic manner can lead to an excellent clinical outcome without compromising the functional integrity of the rotator cuff tendons.

    showed excellent or good outcomes; no fair outcome in none of the patients; and seven (11% poor outcomes. A satisfaction rate of 92% was reported. Postoperative joint motion went from a mean lifting value of 93º to 141º, the mean lateral rotation went from 32º to 48º and the mean medial rotation went from L1 to T10. These differences were regarded as statistically significant. CONCLUSION: The arthroscopic repair of extensive rotator cuff injuries leads to satisfactory outcomes for most of the patients, with a high satisfaction degree.

    Acellular human dermal matrix allografts are now being used to augment and sometimes replace severely damaged rotator cuff tissue. I have been interested in this important aspect of orthopaedics for 15 years and am pleased to have the opportunity to share my personal reflections of some of the highlights in science and the literature that helped get to the point now where we can expect greater than 80% healing even in these difficult cases of revision after massive failed cuff repair. The field of tissue engineering will certainly be a critical part of our rotator cuff surgical future. PMID:27594327

    Full Text Available Lesions of the rotator cuff (RC are among the most frequent tendon injuries. In spite of the developments in both open and arthroscopic surgery, RC repair still very often fails. In order to reduce the failure rate after surgery, several experimental in vitro and in vivo therapy methods have been developed for biological improvement of the reinsertion. This article provides an overview of the current evidence for augmentation of RC reconstruction with growth factors. Furthermore, potential future therapeutic approaches are discussed. We performed a comprehensive search of the PubMed database using various combinations of the keywords "tendon," "rotator cuff," "augmentation," "growth factor," "platelet-rich fibrin," and "platelet-rich plasma" for publications up to 2011. Given the linguistic capabilities of the research team, we considered publications in English, German, French, and Spanish. We excluded literature reviews, case reports, and letters to the editor.

  11. NMR of the rotator cuff. An update

    International Nuclear Information System (INIS)

    The rotator cuff consists of the tendons of the supscapularis, supraspinatus, infraspinatus and teres minor muscles. This group of muscles performs multiple functions and is often stressed during various activities. This explains, why rotator cuff disease is common and the most often cause of shoulder pain and dysfunction in adults. MR imaging still is the most important imaging modality in assessment of rotator cuff disease. It enables the radiologist to make an accurate diagnosis, the basis for an appropriate management. In this article, current concepts with regard to anatomy and imaging diagnosis will be reviewed. The discussion of the complex anatomy is followed by normal and pathologic MR imaging appearances of the rotator cuff including tendinopathy and tearing, and concluding with a review of the postoperative cuff.

  12. Rotator cuff injury: fat suppression MR image

    International Nuclear Information System (INIS)

    We performed the study prospectively to evaluate the advantage of fat suppression MR in the diagnosis of rotator cuff injury. Ten symptomatic patients were studied with both conventional T2WI and FST2WI using chemical shift technique. Each image was analyzed for the assessment of injuries, conspicuity of the lesion, the presence of effusion in subacromical bursae and joint space, and presence of humeral head injury. Arthroscopy was done in 4 patients following MRI. We could made presumptive diagnoses on FSMR as identical as on conventional MR in six cases(1 normal, 2 tendinitis, 2 partial thickness tear, 1 full thickness tear), two of them were confirmed by arthroscopic procedures. Two cases of partial thickness tear proved by arthroscopy were detected on FST2WI, whereas they were considered tendinitis on conventional T2WI. There were another 2 cases who showed tendinitis on FSMR, but normal on conventional T2WI. They, however, were not confirmed by either arthroscopy or surgical procedure. We found the FSMR were superior to conventional T2WI in the conspicuity of lesions and detection of joint effusion and abnormalities on the humeral head. We think FSMR of the shoulder could have significant diagnostic advantages over the conventional spin-echo MR imaging

    2015-01-01

    Full Text Available Purpose: The purpose of this report is to describe a new full-thickness tear pattern of the posterosuperior rotator cuff with reversal healing. We describe the specific radiologic signs associated with this tear pattern and the arthroscopic rotator cuff repair technique. Materials and Methods: A prospective radiologic and clinical study collected all patients with a magnetic resonance imaging arthrogram that underwent an arthroscopic rotator cuff repair over a 1 year period. Results: Among 97 patients, five demonstrated a tear of the posterosuperior rotator cuff with reversal healing. Characteristic radiographic findings included a thicker tendon than normal, the presence of a stump and accumulation of liquid in the superior-medial part of the subacromial bursa, and adhesions between the supraspinatus tendon and the wall of the subacromial bursa. Conclusion: Avulsion of the posterosuperior rotator cuff with reversal healing on its bursal-side is a less common condition. This type of lesion and distinct radiographic signs that can be recognized to facilitate anatomic repair of the rotator cuff. Level of evidence: Level IV.

    Background In arthroscopic surgery, the suture anchor technique has become popular for rotator cuff repair. Preoperative evaluation of the bone microstructure is of utmost importance because, especially in elderly patients, osteoporotic changes may cause anchor pullout, which results in failure of rotator cuff repair. Many groups have reported humeral microstructural analysis; however, most studies were experiments using porcine specimens or human cadavers. In this study, we used multidetecto...

    2012-01-01

    Full Text Available The purpose of this systematic review was to address the treatment of rotator cuff tears by applying tissue engineering approaches to improve tendon healing, specifically platelet rich plasma (PRP augmentation, stem cells, and scaffolds. Our systematic search was performed using the combination of the following terms: “rotator cuff”, “shoulder”, “PRP”, “platelet rich plasma”, “stemcells”, “scaffold”, “growth factors”, and “tissue engineering”. No level I or II studies were found on the use of scaffolds and stem cells for rotator cuff repair. Three studies compared rotator cuff repair with or without PRP augmentation. All authors performed arthroscopic rotator cuff repair with different techniques of suture anchor fixation and different PRP augmentation. The three studies found no difference in clinical rating scales and functional outcomes between PRP and control groups. Only one study showed clinical statistically significant difference between the two groups at the 3-month followup. Any statistically significant difference in the rates of tendon rerupture between the control group and the PRP group was found using the magnetic resonance imaging. The current literature on tissue engineering application for rotator cuff repair is scanty. Comparative studies included in this review suggest that PRP augmented repair of a rotator cuff does not yield improved functional and clinical outcome compared with non-augmented repair at a medium and long-term followup.

  19. Systematics of injuries of the rotator cuff and biceps tendon

    International Nuclear Information System (INIS)

    Injuries of the rotator cuff and the biceps tendon demonstrate different patterns, which can be recognized clinically and radiologically. These patterns are impingement syndrome with additional trauma, isolated trauma of the rotator cuff and shoulder dislocation causing rotator cuff tears. Furthermore, it is clinically crucial to evaluate the extent of a rotator cuff injury. Magnetic resonance imaging (MRI) is the modality of choice to differentiate these patterns. (orig.)

  20. MRI of the rotator cuff and internal derangement

    International Nuclear Information System (INIS)

    Disease to the rotator cuff is the most common cause of shoulder pain and dysfunction in adults. This group of muscles performs multiple functions and is often stressed during various activities. The anatomy and physiology of the rotator cuff is complex and interconnected to other muscle groups in the shoulder. One must take the anatomic status of the rotator cuff tendons into account when planning the treatment of the rotator cuff injury. Diagnostic imaging of the rotator cuff, performed by MRI, provides valuable information about the nature of the injury. In this article, we will review the various types and causes of rotator cuff injuries, normal MR anatomy, function, patho-anatomy, and the biomechanics of the rotator cuff. We will also review shoulder impingement syndromes

    We conducted a study to evaluate in vivo tension applied to the rotator cuff tendon positioned at the medial versus lateral footprint during arthroscopic rotator cuff repair. We evaluated 20 consecutive patients who underwent arthroscopic rotator cuff repair. During repair, a grasper was inserted through a lateral portal, and a digital weigh scale was attached. The tendon was grasped and translated to the medial footprint, and tension recorded. After a relaxation period, the tendon edge was translated to the lateral footprint, and tension recorded. Mean (SD) tension was 0.41 (0.33) pound when tendons were positioned at the medial footprint and 2.21 (1.20) pounds when they were positioned at the lateral footprint, representing a 5.4-fold difference (P < .0001). For smaller tears (≤20 mm anterior-posterior), 7.6 times less tension was applied to the tendons when pulled to the medial versus lateral footprint. For larger tears, 4.1 times less tension was applied to the tendons when pulled to the medial versus lateral footprint. This study demonstrated a significant, 5.4-fold increase in tension when the tendon edge was reduced to the lateral as opposed to the medial footprint in vivo. PMID:26991588

  5. MR arthrography of partial thickness tears of the undersurface of therotator cuff: and arthroscopic correlation

    International Nuclear Information System (INIS)

    This study evaluated the efficacy of MR arthrography (MR-ARTH) in diagnosing these tears. Design and patients The study design was a retrospective review of medical records of patients who had presented with refractory shoulder complaints and subsequently undergone MR arthrography with multiple signal MRI sequences followed by shoulder arthroscopy. Of particular interest were patients who had oblique T1 fat suppression (COT1FS), coronal oblique T2 (COT2), and coronal oblique T2 fat suppression (COT2FS) images taken. Seventy-six subjects met the study criteria. Investigators examined the MR-ARTH images from these patients' charts while blinded as to arthroscopic results, clinical signs and symptoms. Results Based on COT1FS images, investigators identified nine subjects as having had full thickness tears, 28 as having had partial thickness tears of the undersurface of the rotator cuff (PRTC), and 39 as having had intact RTC. These results were compared to actual findings at arthroscopy: nine full thickness tears, 26 of 28 with PRTC and 34 of 39 intact. The sensitivity of MR-ARTH was 84%, with a positive predictive value of 93%. The overall accuracy was 91% (69/76). The specificity was 96%. That is, if a PRTC was not seen on the MR-ARTH images, it was very unlikely to exist. COT2 and COT2FS sequences failed to increase sensitivity and overall efficacy of MRI. Conclusion PRTC can be diagnosed accurately by MR-ARTH with gadopentatate contrast. A COT1FS sequence is recommended for evaluation when tears are suspected

    Irreparable rotator cuff tears ( IRCTs ), due to fatty inifltration and tendon retraction of the rotator cuff, is a challenge for orthropaedic surgeons, especially surgeons of sports medicine. It also has a huge influence on shoulder range of motion ( ROM ) loss and life quality. Currently, the treatment strategies of IRCTs still remain controversial, including conservative procedures, arthroscopic acromioplasty, partial repair, rotator cuff reconstruction and shoulder preserving athroplasty. With the popularity of new biomaterial application, there is another option to IRCTs surgery. However, healing effects of the new material with bone and tendon, mechanical strength, rotator cuff functions are still in need to be explored.

    Full Text Available Background: Rotator cuff tears are a common source of shoulder pain. The incidence increases with age and is most frequently due to degeneration of the tendon, rather than injury. This study is done to see whether in patients having established rotator cuff tears with co-morbidities like hypertension diabetes, epilepsy, etc. a surgical repair is worthwhile or whether it is better to leave such patients alone in order to give them a better quality of life. Methods: A total of 35 patients with co-morbidities, treated by a single surgeon of which 8 by open method, 19 with arthroscopic assisted mini open rotator cuff repair and 8 entire arthroscopically were evaluated retrospectively. Small tears (<1 cm, medium tears (1-3 cm; large tears (3-5 cm were addressed by the same surgical procedure using bone tunnels, suture anchors, or a combination of both. The patients were evaluated by history, examination, pain scores and constant scores. Results: As compared to patients with no co-morbidities, these patients took longer time for healing especially diabetics. Despite that 27 patients had excellent pain relief, 5 good and 3 poor pain relief. Constant scores improved in all patients. Conclusion: Patients with co-morbidities take longer time to heal, yet the final outcome which is attained and relief of pain and relief in the form of activities of daily living that we could offer the patients makes the surgery worthwhile. It is well worth operating on patients with co-morbidities and a rotator cuff tear, giving them a better pain free life and better activities of daily living.

    Full Text Available ABSTRACT OBJECTIVE: To describe occurrences of septic glenohumeral arthritis among patients with arthropathy of the rotator cuff, and to highlight the importance of correct diagnosis and surgical procedures. METHODOLOGy: Eight surgical drains were installed in seven patients with glenohumeral pyoarthritis. All the patients presented arthropathy of the rotator cuff (four males and three females. Six patients presented pyoarthritis in the dominant shoulder. The age range was from 53 to 93 years (mean: 74 years. The mean duration of the symptoms before the surgical lavage was six weeks. Six patients underwent treatment consisting of a combination of arthroscopic irrigation and debridement, and one patient was treated by means of open arthrotomy. All the patients received systemic antibiotic therapy in accordance with their bacterial sensitivity. RESULTS: All seven patients achieved satisfactory results, taking into consideration especially the improvement of pain and the patients' satisfaction. The functional assessment was performed using the University of California Los Angeles (UCLA scale. Only one patient needed to go through another arthroscopic procedure. Staphylococcus aureus was isolated from four cultures and Escherichia coli from one culture. There were two situations in which the patients used empirical antibiotic therapy and the cultures showed negative results. Among the associated procedures, tenotomy of the biceps was performed in four cases, resection of the lateral third of the clavicle due to osteomyelitis in one case and arthrotomy of the knee in one case. CONCLUSION: Surgical treatment was effective in the cases of arthritis associated with arthropathy of the rotator cuff. In patients with arthropathy of the rotator cuff and subclinically altered laboratory signs, the possibility of pyoarthritis should always be suspected.

    Full Text Available High-resolution ultrasound has gained increasing popularity as an aid in the diagnosis of rotator cuff pathology. With the advent of portable machines, ultrasound has become accessible to clinicians. Aim: This study was conducted to evaluate the accuracy and reliability of ultrasound in diagnosing rotator cuff tears by a shoulder surgeon and comparing their ability to that of a musculoskeletal radiologist. Materials and Methods: Seventy patients undergoing shoulder arthroscopy for rotator cuff pathology underwent preoperative ultrasonography (US. All patients were of similar demographics and pathology. The surgeon used a Sonosite Micromax portable ultrasound machine with a 10-MHz high frequency linear array transducer and the radiologist used a 9-12 MHz linear array probe on a Siemens Antares machine. Arthroscopic diagnosis was the reference standard to which ultrasound findings were compared. Results: The sensitivity in detecting full thickness tears was similar for both the surgeon (92% and the radiologist (94%. The radiologist had 100% sensitivity in diagnosing partial thickness tears, compared to 85.7% for the surgeon. The specificity for the surgeon was 94% and 85% for the radiologist. Discussion: Our study shows that the surgeons are capable of diagnosing rotator cuff tears with the use of high-resolution portable ultrasound in the outpatient setting. Conclusion: Office ultrasound, by a trained clinician, is a powerful diagnostic tool in diagnosing rotator cuff tears and can be used effectively in running one-stop shoulder clinics.

    Rotator cuff disease impacts over 50% of the population over 60, with reports of incidence being as high as 90% within this population, causing pain and possible loss of function. The rotator cuff is composed of muscles and tendons that work in tandem to support the shoulder. Heavy use of these muscles can lead to rotator cuff tear, with the most common causes is age-related degeneration or sport injuries, both being a function of overuse. Tears ranges in severity from partial thickness tear to total rupture. Diagnostic techniques are based on physical assessment, detailed patient history, and medical imaging; primarily X-ray, MRI and ultrasonography are the chosen modalities for assessment. The final treatment technique and imaging modality; however, is chosen by the clinician is at their discretion. Ultrasound has been shown to have good accuracy for identification and measurement of full-thickness and partial-thickness rotator cuff tears. In this study, we report on the progress and improvement of our method of transduction and analysis of in situ measurement of rotator cuff biomechanics. We have improved the ability of the clinician to apply a uniform force to the underlying musculotendentious tissues while simultaneously obtaining the ultrasound image. This measurement protocol combined with region of interest (ROI) based image processing will help in developing a predictive diagnostic model for treatment of rotator cuff disease and help the clinicians choose the best treatment technique.

  13. Progression from calcifying tendinitis to rotator cuff tear

    International Nuclear Information System (INIS)

    This report documents the clinical, radiographic and histologic findings in a 46-year-old man with calcifying tendinitis in his left shoulder which progressed to rotator cuff tear. The patient had a 1-year history of repeated calcifying tendinitis before being referred to our hospital. On the initial visit, radiographs and magnetic resonance imaging (MRI) revealed calcium deposition localized in the supraspinatus tendon without apparent tear. Three months after the first visit, MRI revealed a partial-thickness rotator cuff tear at the site of calcium deposition. Surgical and histologic findings demonstrated that calcium deposition was the cause of cuff rupture. To our knowledge, based on a review of the English literature, this is the first case report in which the progression from calcifying tendinitis to rotator cuff tear has been serially observed.

    The aim of this study was to evaluate the accuracy of simple radiography, ultrasound and magnetic resonance imaging (MRI) in diagnosing rotator cuff injuries, comparing their findings with open or arthroscopic surgery findings. Methods: Protocols of the Shoulder and Elbow Surgery Service for patients undergoing surgical treatment for rotator cuff injuries diagnosed by means of radiography, ultrasound and/or MRI between 2002 and 2007 were evaluated. Based on the data gathered, we analyzed the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of these complementary examinations, compared with the findings during the surgical procedures. Results: This study included 147 patients with a mean age of 46.09 years. All the patients had undergone a radiography examination, 101 had undergone ultrasound examination and 72 had undergone MRI. We found sensitivity of 13.8%, specificity of 2.6% and accuracy of 30% with radiography; sensitivity of 57.6%, specificity of 29.6% and accuracy of 51.4% with ultrasound; and sensitivity of 86.6%, specificity of 22.2% and accuracy of 63.3% with MRI. Conclusion: Radiography was found to be a specific examination when the mirror sign was present. MRI and ultrasound were shown to be reliable methods with high accuracy for diagnosing rotator cuff injuries. PMID:27022589

    The success of rotator cuff repair (RCR) surgery can be measured clinically (validated outcome scores, range of motion) as well as structurally (re-tear rates using imaging studies). Regardless of repair type or technique, most studies have shown that patients do well clinically. However, multiple studies have also shown that structurally, the failure rate can be very high. A variety of factors, including poor tendon quality, age over 63 years, smoking, advanced fatty infiltration into the muscle, and the inability of the tendon to heal to bone, have been implicated as the cause of the high re-tear rate in RCRs. The suture-tendon interface is felt to be the weakest link in the RCR construct, and suture pullout through the tendon is believed to be the most common method of failure. This review of the published literature seeks to determine if there is support for augmentation of RCR with acellular dermal matrices to strengthen the suture-tendon interface and reduce the re-tear rate.

  18. Diagnostic accuracy of ultrasound for rotator cuff tears in adults: A systematic review and meta-analysis

    International Nuclear Information System (INIS)

    Aim: To determine the diagnostic accuracy of ultrasound to detect partial and complete thickness rotator cuff tears based on all available clinical trials. Materials and methods: An electronic search of databases registering published and unpublished literature was conducted. All diagnostic accuracy studies that directly compared the accuracy of ultrasound (the index test) to either arthroscopic or open surgical findings (the reference test) for rotator cuff tear were included. The methodological quality of each included study was assessed using the QUADAS form. When appropriate, pooled sensitivity and specificity analysis was conducted, with an assessment of the summary receiver operating characteristic (ROC) curve for each analysis. Results: Sixty-two studies assessing 6007 patients and 6066 shoulders were included. Ultrasonography had good sensitivity and specificity for the assessment of partial thickness (sensitivity 0.84; specificity 0.89), and full-thickness rotator cuff tears (sensitivity 0.96; specificity 0.93). However, the literature poorly described population characteristics, assessor blinding, and was based on limited sample sizes. The literature assessing transducer frequency was particularly small in size. Conclusion: Ultrasonography is an appropriate radiological technique for the assessment of rotator cuff tears with an acceptable sensitivity and specificity. The diagnostic test accuracy of ultrasound is superior for the detection of full-thickness compared to partial-thickness cuff tears. Further study assessing the effect of transducer frequency is warranted.

  20. Rotator cuff tears noncontrast MRI compared to MR arthrography

    International Nuclear Information System (INIS)

    To compare the accuracy of indirect magnetic resonance arthrography and noncontrast magnetic resonance imaging for diagnosing rotator cuff tears. In total, 333 patients who underwent noncontrast magnetic resonance imaging or indirect magnetic resonance arthrography were included retrospectively. Two musculoskeletal radiologists evaluated the images for the presence of supraspinatus-infraspinatus and subscapularis tendon tears. The overall diagnostic performance was calculated using the arthroscopic findings as the reference standard. Statistical differences between the diagnostic performances of the two methods were analyzed. Ninety-six and 237 patients who underwent noncontrast magnetic resonance imaging and indirect magnetic resonance arthrography were assigned into groups A and B, respectively. Sensitivity for diagnosing articular-surface partial-thickness supraspinatus-infraspinatus tendon tear was slightly higher in group B than in group A. Statistical significance was confirmed by multivariate analysis using the generalized estimating equation (p = 0.046). The specificity for diagnosing subscapularis tendon tear (85 % vs. 68 %, p = 0.012) and grading accuracy (57 % vs. 40 %, p = 0.005) was higher in group B than in group A; the differences were statistically significant for one out of two readers. Univariate analysis using the generalized estimating equation showed that the accuracy for diagnosing subscapularis tendon tear in group B was higher than in group A (p = 0.042). There were no statistically significant differences between the diagnostic performances of both methods for any other parameters. Indirect magnetic resonance arthrography may facilitate more accurate diagnosis and grading of subscapularis tendon tears compared with noncontrast magnetic resonance imaging. (orig.)

    Full Text Available Abstract Background With advances in arthroscopic surgery, many techniques have been developed to increase the tendon-bone contact area, reconstituting a more anatomic configuration of the rotator cuff footprint and providing a better environment for tendon healing. Methods We present an arthroscopic rotator cuff repair technique which uses suture bridges to optimize rotator cuff tendon-footprint contact area and mean pressure. Results Two medial row 5.5-mm Bio-Corkscrew suture anchors (Arthrex, Naples, FL, which are double-loaded with No. 2 FiberWire sutures (Arthrex, Naples, FL, are placed in the medial aspect of the footprint. Two suture limbs from a single suture are both passed through a single point in the rotator cuff. This is performed for both anchors. The medial row sutures are tied using the double pulley technique. A suture limb is retrieved from each of the medial anchors through the lateral portal, and manually tied as a six-throw surgeon's knot over a metal rod. The two free suture limbs are pulled to transport the knot over the top of the tendon bridge. Then the two free suture limbs that were used to pull the knot down are tied. The end of the sutures are cut. The same double pulley technique is repeated for the other two suture limbs from the two medial anchors, but the two free suture limbs are used to produce suture bridges over the tendon, by means of a Pushlock (Arthrex, Naples, FL, placed 1 cm distal to the lateral edge of the footprint. Conclusion This technique maximizes the advantages of two techniques. On the one hand, the double pulley technique provides an extremely secure fixation in the medial aspect of the footprint. On the other hand, the suture bridges allow to improve pressurized contact area and mean footprint pressure. In this way, the bony footprint in not compromised by the distal-lateral fixation, and it is thus possible to share the load between fixation points. This maximizes the strength of the repair

    Calcifying tendinitis occurs most commonly in the rotator cuff tendons, particularly involving the supraspinatus tendon insertion, and is often asymptomatic. Cortical erosion secondary to calcifying tendinitis has been reported in multiple locations, including in the rotator cuff tendons. We present a pathologically proven case of symptomatic calcifying tendinitis involving the infraspinatus tendon with cortical erosion with correlative radiographic, CT, and MR findings. The importance of considering this diagnosis when evaluating lytic lesions of the humerus and the imaging differential diagnosis of calcifying tendinitis and cortical erosion are discussed. (orig.)

  7. Correlation between Rotator Cuff Tears and Systemic Atherosclerotic Disease

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the association of aortic arch calcification, a surrogate marker of atherosclerosis, with rotator cuff tendinosis and tears given the hypothesis that decreased tendon vascularity is a contributing factor in the etiology of tendon degeneration. A retrospective review was performed to identify patients ages 50 to 90 years who had a shoulder MRI and a chest radiograph performed within 6 months of each other. Chest radiographs and shoulder MRIs from 120 patients were reviewed by two sets of observers blinded to the others' conclusions. Rotator cuff disease was classified as tendinosis, partial thickness tear, and full thickness tear. The presence or absence of aortic arch calcification was graded and compared with the MRI appearance of the rotator cuff. The tendon tear grading was positively correlated with patient age. However, the tendon tear grading on MRI was not significantly correlated with the aorta calcification scores on chest radiographs. Furthermore, there was no significant correlation between aorta calcification severity and tendon tear grading. In conclusion, rotator cuff tears did not significantly correlate with aortic calcification severity. This suggests that tendon ischemia may not be associated with the degree of macrovascular disease

    Twenty-six patients with chief complaint of shoulder pain who underwent both ultrasonographic examination and arthrography of the shoulder were analyzed. Ten out of 12 cases with clinical impression of frozen shoulder, showed normal findings on the ultrasonographic examination of the shoulder. Among these ten cases, nine cases showed adhesive capsulitis and one case showed rotator cuff tear on arthrography. Among six cases with the clinical impression of rotator cuff tear, five cases showed rotator cuff tear and one case showed combined calcific tendinitis and adhesive capsulitis on ultrasonographic examination. In arthrography, four cases of rotator cuff tear, one case of calcific tendinitis and biceps tendinitis and one case of normal finding were diagnosed. For the remaining eight cases in the ultrasonographic examination, normal finding or biceps tendinitis were found and for the remaining of the cases in arthrography adhesive capsulitis were found. With the above results, we recommend that the shoulder ultrasonography as the first line diagnostic modality for a patient with chief complaint of shoulder pain.

    To evaluate the feasibility of MR arthrography and ultrasonography in evaluating shoulder pain. The subject group consisted of all patients who visited our institute complaining of shoulder pain or instability form June 2002 to December 2004. There were a total of 92 patients with an mean age of 48. On the basis of arthroscopic results, the sensitivity, specificity, and accuracy of ultrasonography and MR arthrography were evaluated by comparing them with each other. In the diagnosis of separateness tendon tears, ultrasonography had sensitivity and specificity of 100% and 64%, respectively, whereas MR arthrography had sensitivity and specificity of 80% and 94%, respectively. Ultrasonography also had high sensitivity and specificity in the diagnosis of subscapularis tendon tears (100% and 90%). MR arthrography was appropriate for identifying glenoid labral abnormalities (sensitivity, 95% and specificity, 61%). Similar results from ultrasonography and MR arthrography were obtained in the diagnosis of subscapular tendon tears or full-thickness tears of the rotator cuff tendons (kappa value, 0.644 and 0.911). While evaluating rotator cuff abnormalities, ultrasonography was appropriate for screening, whereas MR arthrography was useful to confirm the results of the ultrasonography

    Full Text Available ABSTRACTA painful shoulder is a very common complaint among athletes, especially in the case of those in sports involving throwing. Partial lesions of the rotator cuff may be very painful and cause significant functional limitation to athletes' sports practice. The incidence of partial lesions of the cuff is variable (13-37%. It is difficult to make the clinical and radiological diagnosis, and this condition should be borne in mind in the cases of all athletes who present symptoms of rotator cuff syndrome, including in patients who are diagnosed only with tendinopathy. OBJECTIVE: To evaluate the epidemiological behavior of partial lesions of the rotator cuff in both amateur and professional athletes in different types of sports. METHODS: We evaluated 720 medical files on athletes attended at the shoulder service of the Discipline of Sports Medicine at the Sports Traumatology Center, Federal University of São Paulo. The majority of them were men (65%. Among all the patients, 83 of them were diagnosed with partial lesions of the rotator cuff, by means of ultrasonography or magnetic resonance, or in some cases using both. We applied the binomial test to compare the proportions found. RESULT: It was observed that intra-articular lesions predominated (67.6% and that these occurred more frequently in athletes in sports involving throwing (66%. Bursal lesions occurred in 32.4% of the athletes, predominantly in those who did muscle building (75%. CONCLUSION: Intra-articular lesions are more frequent than bursal lesions and they occur predominantly in athletes in sports involving throwing, while bursal lesions were more prevalent in athletes who did muscle building.

    Background and purpose - Arthroscopic acromioplasty is still commonly used in the treatment of shoulder impingement syndrome, even though its benefits are questioned; randomized controlled studies have not shown any benefits when compared to non-operative treatment. In this randomized study, we investigated whether operative treatment protects from later rotator cuff rupture and whether it has any effect on the development of rotator cuff muscle volume. Patients and methods - 140 stage-II impingement patients were randomized to a structured exercise group (n = 70) or to an operative group (n = 70). In the operative group, arthroscopic acromioplasty was performed, after which a similar structured exercise program was begun. MRI of the shoulder was done at baseline and at 5 years. Results - There were no statistically significant differences in either the amount of perforating ruptures of the supraspinatus tendon or in the changes in muscle volume at 5 years. The grading of muscle fatty degeneration showed worse results in the operative group, but this difference was not statistically significant. Interpretation - In this study, we found that arthroscopic acromioplasty does not have any long-term benefit based on radiological findings of muscle volumes. Also, the frequency of later rotator cuff rupture was similar irrespective of whether or not surgery was performed. Acromioplasty is not justified as a treatment for dynamic shoulder impingement syndrome. PMID:27348693

    Introduction Professional sports injuries are usually all dealt with at one single operation to return the player to the sport after appropriate rehabilitation. We questioned the assumption that rotator cuff tears must be repaired concurrently with instability syndromes, and aimed to allow a professional rugby league player to achieve career goals by NOT correcting all pathology at one surgery. Case Presentation A professional rugby league player presented with acute shoulder instability on a setting of a chronic full thickness rotator cuff tear. We performed an “in season” arthroscopic stabilization on an elite rugby league player, leaving a previously diagnosed large full thickness rotator cuff tear untreated. This allowed aggressive rehabilitation and return to contact competition at 12 weeks post-surgery. The player achieved a long held career goal of winning a premiership ring before undertaking rotator cuff repair at the end of the season. Latest follow up at seven years (still at elite level) demonstrated an asymptomatic shoulder. Conclusions The assumption that all pathology found at surgical exploration requires correction to play at elite level is not universally correct. We postulate that whilst rotator cuff deficiency has severe long-term sequelae, it is shoulder instability alone that prevents high level contact sports participation. Career goal management is an important part of managing elite level athletes. We have demonstrated that by careful management of the specific pathology preventing participation can allow elite athletes to achieve career goals without compromising long-term health.

    The content and quality of Internet websites are not governed or regulated. Therefore, patients who consult the Internet may receive outdated or incorrect medical information. Researchers have analyzed the quality of web information about various orthopedic surgeries, but no such analysis has been performed on websites covering rotator cuff repair. We conducted a study to evaluate and analyze rotator cuff repair information available to the general public through the Internet; to assess changes in the quality of information over time; to determine if sites sponsored by academic institutions offered higher-quality information; and to assess whether the readability of the material varied according to DISCERN scores. Two Internet searches were conducted, in 2011 and 2014. The 3 most commonly used search engines were used to search for rotator cuff repair. The first 50 websites from each search engine were evaluated for authorship and content. The DISCERN instrument was used to analyze the quality of each website's health information. The 2011 search revealed 21% of websites were associated with an academic institution, 38% were authored by a hospital or physician group, and 11.5% were industry-sponsored. The 2014 search revealed a similar distribution of contributors. The highest DISCERN scores were given to academic institution websites (51.6) and public education websites (49). There was no correlation between readability and DISCERN scores. Websites associated with academic institutions produced the highest-quality medical information. Over the past few years, authorship and content have changed little with respect to Internet information about rotator cuff repair. PMID:26991581

    Calcifying tendinitis of the rotator cuff is a common disorder; its underlying mechanism still remains unknown. Although details of the clinical presentation(s) and pathological changes which are associated with calcific tendinitis are available, conservative management of this condition remains a topic of debate. About 90% of the patients can be treated non – operatively, but as some are resistant to conservative treatment; newer techniques or surgery should be indicated.

    As rotator cuff repair techniques have improved, failure of the tendon to heal to the proximal humerus is less likely to occur from weak tendon-to-bone fixation. More likely causes of failure include biologic factors such as intrinsic tendon degeneration, fatty atrophy, fatty infiltration of muscle, and lack of vascularity of the tendons. High failure rates have led to the investigation of biologic augmentation to potentially enhance the healing response. Histologic studies have shown that restoration of the rotator cuff footprint during repair can help reestablish the enthesis. In animal models, growth factors and their delivery scaffolds as well as tissue engineering have shown promise in decreasing scar tissue while maintaining biomechanical strength. Platelet-rich plasma may be a safe adjuvant to rotator cuff repair, but it has not been shown to improve healing or function. Many of these strategies need to be further defined to permit understanding of, and to optimize, the biologic environment; in addition, techniques need to be refined for clinical use. PMID:21980023

    2015-12-01

    Fatty degeneration of the rotator cuff muscles is an irreversible change resulting from chronic rotator cuff tear and is associated with poor clinical outcomes following rotator cuff repair. We evaluated the effect of Tamoxifen, a competitive estrogen receptor inhibitor, on fatty degeneration using a mouse model for chronic rotator cuff tear. Sixteen adult mice were divided into two diet groups (Tamoxifen vs. Regular) and subjected to surgical creation of a large rotator cuff tear and suprascapular nerve transection in their left shoulder with the right shoulder serving as a control. The rotator cuff muscles were harvested at 16 weeks and subjected to histology and RT-PCR for adipogenic and myogenic markers. Histology showed substantially decreased atrophy and endomysial inflammation in Tamoxifen group, but no significant differences in the amount of intramuscular adipocytes and lipid droplets compared to the Regular group. With RT-PCR, the operated shoulders showed significant upregulation of myogenin and PPAR-γ, and downregulation of myostatin compared to the nonsurgical shoulder. No significant differences of gene expression were found between the two diet groups. Our study demonstrated that tamoxifen diet leads to decreased muscle atrophy and inflammatory changes following chronic rotator cuff tear, but has no apparent effect on adipogenesis. PMID:26121952

    Full Text Available OBJECTIVES: Rotator cuff tear is a common cause of shoulder diseases. Correct diagnosis of rotator cuff tears can save patients from further invasive, costly and painful tests. This study used predictive data mining and Bayesian theory to improve the accuracy of diagnosing rotator cuff tears by clinical examination alone. METHODS: In this retrospective study, 169 patients who had a preliminary diagnosis of rotator cuff tear on the basis of clinical evaluation followed by confirmatory MRI between 2007 and 2011 were identified. MRI was used as a reference standard to classify rotator cuff tears. The predictor variable was the clinical assessment results, which consisted of 16 attributes. This study employed 2 data mining methods (ANN and the decision tree and a statistical method (logistic regression to classify the rotator cuff diagnosis into "tear" and "no tear" groups. Likelihood ratio and Bayesian theory were applied to estimate the probability of rotator cuff tears based on the results of the prediction models. RESULTS: Our proposed data mining procedures outperformed the classic statistical method. The correction rate, sensitivity, specificity and area under the ROC curve of predicting a rotator cuff tear were statistical better in the ANN and decision tree models compared to logistic regression. Based on likelihood ratios derived from our prediction models, Fagan's nomogram could be constructed to assess the probability of a patient who has a rotator cuff tear using a pretest probability and a prediction result (tear or no tear. CONCLUSIONS: Our predictive data mining models, combined with likelihood ratios and Bayesian theory, appear to be good tools to classify rotator cuff tears as well as determine the probability of the presence of the disease to enhance diagnostic decision making for rotator cuff tears.

    @@ Since partial thickness tears of the rotator cuff were described well by Codman 1 in 1934, they have been extensively discussed in all kinds of literatures.Partial thickness tears of the rotator cuff are now considered to play a more significant role than previously in inducing patients disability. Partialthickness cuff tears deserve more clinical attention. Both accurate diagnosis and proper surgical repair are very essential. The cognition of partialthickness tears has been deepened in the last decades. In this paper we will review the etiology, classification and clinical evaluation of partial thickness tears of the rotator cuff.

    Full Text Available We evaluated the expression of several genes involved in tissue remodelling and bone development in patients with calcific tendinopathy of the rotator cuff. Biopsies from calcified and non-calcified areas were obtained from 10 patients (8 women and 2 men; average age: 55 years; range: 40-68 with calcific tendinopathy of the rotator cuff. To evaluate the expression of selected genes, RNA extraction, cDNA synthesis and quantitative polymerase chain reaction (PCR were performed. A significantly increased expression of tissue transglutaminase (tTG2 and its substrate, osteopontin, was detected in the calcific areas compared to the levels observed in the normal tissue from the same subject with calcific tendinopathy, whereas a modest increase was observed for catepsin K. There was also a significant decrease in mRNA expression of Bone Morphogenetic Protein (BMP4 and BMP6 in the calcific area. BMP-2, collagen V and vascular endothelial growth factor (VEGF did not show significant differences. Collagen X and matrix metalloproteinase (MMP-9 were not detectable. A variation in expression of these genes could be characteristic of this form tendinopathy, since an increased level of these genes has not been detected in other forms of tendon lesions.

    Evaluation and diagnosis of diseases of the muscles within the rotator cuff can be done using different modalities, being the Magnetic Resonance the method more widely used. There are criteria to evaluate the degree of fat infiltration and muscle atrophy, but these have low accuracy and show great variability inter and intra observer. In this paper, an analysis of the texture features of the rotator cuff muscles is performed to classify them and other tissues. A general supervised classification approach was used, combining forward-search as feature selection method with kNN as classification rule. Sections of Magnetic Resonance Images of the tissues of interest were selected by specialist doctors and they were considered as Gold Standard. Accuracies obtained were of 93% for T1-weighted images and 92% for T2-weighted images. As an immediate future work, the combination of both sequences of images will be considered, expecting to improve the results, as well as the use of other sequences of Magnetic Resonance Images. This work represents an initial point for the classification and quantification of fat infiltration and muscle atrophy degree. From this initial point, it is expected to make an accurate and objective system which will result in benefits for future research and for patients’ health.

  12. Standard sonography and arthrosonography in the study of rotator cuff tears

    International Nuclear Information System (INIS)

    Purpose. The aim of this study was to evaluate the sensitivity of ultrasonography, integrating standard ultrasound and arthrosonography after injecting a saline solution into the glenohumeral cavity in cases of suspected rotator cuff tears. Materials and methods. We respectively examinated 40 patients awaiting shoulder arthroscopy for suspected or diagnosed tears of the rotator cuff. A radiologist, unaware of the pre-operative diagnosis, performed an ultrasound scan on all the patients before and after the injection of saline solution into the glenohumeral cavity. The parameters considered were presence or absence of a rotator cuff injury; type of injury according to Snyder and its extent along the longitudinal and transverse planes; presence or absence of effusion into the articular cavity; subacromial/subdeltoid bursal distension. All the patients underwent arthroscopy either the same day of the day after the ultrasound examination. Results. Standard sonography showed 26 complete rotator cuff tears (type C according to Snyder), 2 partial tears (type B according to Snyder) and 12 intact rotator cuffs. Arthrosonography detected 31 complete rotator cuff tears (type C according to Snyder), 1 partial tear (type B according to Snyder) and 8 intact rotator cuffs. Arthroscopy identified 32 complete rotator cuff tears (type C according to Snyder), 1 partial tear (type B according to Snyder) and 8 intact rotator cuffs. Analysis of the results shows that, taking arthroscopy as the gold standard, the sensitivity of normal sonography is 81.2%, whereas that of arthosonography is 96.8% (p<0.05). Conclusions. On the basis of the data obtained in this study, standard sonography , integrated with the injection of a saline solution into the glenohumeral cavity, considerably increases the diagnostic sensitivity for rotator cuff tears. The authors suggest that arthrosonography can be used in the event of suspected rotator tears, when MRI is contraindicated

    The rotator cuff consists of the tendons of the supscapularis, supraspinatus, infraspinatus and teres minor muscles. This group of muscles performs multiple functions and is often stressed during various activities. This explains, why rotator cuff disease is common and the most often cause of shoulder pain and dysfunction in adults. MR imaging still is the most important imaging modality in assessment of rotator cuff disease. It enables the radiologist to make an accurate diagnosis, the basis for an appropriate management. In this article, current concepts with regard to anatomy and imaging diagnosis will be reviewed. The discussion of the complex anatomy is followed by normal and pathologic MR imaging appearances of the rotator cuff including tendinopathy and tearing, and concluding with a review of the postoperative cuff.

    Full Text Available ABSTRACT Anatomical variations at the origin of the biceps tendon have been described by several authors, but occurrences of an origin in the supraspinatus are rare. It is unclear whether this variation might contribute toward pathological conditions of the shoulder. Our objective here was to describe a case of an anatomical variation in the origin of the tendon of the long head of the biceps. The clinical information, preoperative images and arthroscopic images relating to a patient with an aberrant origin of the long head of the biceps, which was observed during shoulder arthroscopy, were reviewed. In this case study, the origin of the biceps was found in the rotator cuff, without any origin from the supraglenoid tubercle or upper labrum. This variant did not seem to contribute toward the pathological condition of the shoulder, and standard treatment for the concomitant condition was sufficient for treating it.

  16. Evaluation of post-exercise magnetic resonance images of the rotator cuff

    International Nuclear Information System (INIS)

    Objective. To examine the effect of strenuous exercise on the magnetic resonance imaging (MRI) characteristics of the rotator cuff tendon. A second objective was to define an optimal time to image the rotator cuff and possibly eliminate exercise-induced false positives. Design and patients. Five male subjects from 24 to 38 years old with normal rotator cuffs by history, physical examination, and screening MRI underwent a rotator cuff exercise session on the Biodex System 2 (Biodex, Shirley, New York). The exercise sessions were followed by sequential MRI scans of the exercised shoulder. These were performed immediately and at 8 h and 24 h after exercise. Results and conclusions. The rotator cuff tendon and subacromial-subdeltoid bursal signal remained unchanged from the pre-exercise through the 24-h post-exercise scans. The rotator cuff muscle signal was increased in five of five subjects on the immediate post-exercise fat-suppressed T2-weighted images. This signal returned to baseline by the 8-h scan. Positive findings of rotator cuff pathology on MRI after strenuous athletic activity should not be discounted as normal exercise-induced changes. Also, diagnostic MRI scanning may take place after a practice session without an increased risk of false positives. (orig.). With 1 fig

    To compare the accuracy between a three-dimensional (3D) indirect isotropic T1-weighted fast spin-echo (FSE) magnetic resonance (MR) arthrography and a conventional two-dimensional (2D) T1-weighted sequences of indirect MR arthrography for diagnosing rotator cuff tears. The study was approved by our Institutional Review Board. In total, 205 patients who had undergone indirect shoulder MR arthrography followed by arthroscopic surgery for 206 shoulders were included in this study. Both conventional 2D T1-weighted FSE sequences and 3D isotropic T1-weighted FSE sequence were performed in all patients. Two radiologists evaluated the images for the presence of full- or partial-thickness tears in the supraspinatus-infraspinatus (SSP-ISP) tendons and tears in the subscapularis (SSC) tendons. Using the arthroscopic findings as the reference standard, the diagnostic performances of both methods were analyzed by the area under the receiver operating characteristic curve (AUC). Arthroscopy confirmed 165 SSP-ISP tendon tears and 103 SSC tendon tears. For diagnosing SSP-ISP tendon tears, the AUC values were 0.964 and 0.989 for the 2D sequences and 3D T1-weighted FSE sequence, respectively, in reader I and 0.947 and 0.963, respectively, in reader II. The AUC values for diagnosing SSC tendon tears were 0.921 and 0.925, respectively, for reader I and 0.856 and 0.860, respectively, for reader II. There was no significant difference between the AUC values of the 2D and 3D sequences in either reader for either type of tear. 3D indirect isotropic MR arthrography with FSE sequence and the conventional 2D arthrography are not significantly different in terms of accuracy for diagnosing rotator cuff tears.

    Full Text Available Background: Pathology of the long head of the biceps tendon (LHB is commonly associated with rotator cuff tears (RCTs. Superior labral anterior-posterior (SLAP lesions can also occur with RCTs. The purpose of this study was to include SLAP lesions as part of LHB pathology in surgical cases of RCT and define the role of SLAP lesions in RCTs.Methods: We retrospectively evaluated clinical data from 176 cases of complete RCT undergoing surgery. During surgery, the LHB was arthroscopically examined. A modified 6-type classification was used to describe the LHB pathology in these cases: tendinitis, subluxation, dislocation, partial tear, complete rupture and SLAP lesions. The relationship of LHB pathology to different characteristics of RCTs was statistically analyzed.Results: Of RCT cases, 33% had Type 1 (tendinitis, 11% had Type 2 (subluxation, 9% had Type 3 (dislocation, 16% had Type 4 (partial tear, 7% had Type 5 (complete rupture and 6% had Type 6 (SLAP lesions. The remaining 18% of cases had no obvious LHB pathology. LHB pathology were associated with RCTs of a long duration (> 3 months, large area (> 5 cm2, and multiple or subscapularis tendon involvement. Seventy four percent of patients with affected shoulders underwent simultaneous surgery for both LHB pathology and RCTs.Conclusion: Most patient with RCTs with chronic, massive, and multiple or subscapularis tendon involvement also had LHB injury. SLAP lesions, which we classified as a subgroup of LHB pathology, should be identified during rotator cuff surgery and treated appropriately.

  19. Tendon patch grafting using the long head of the biceps for irreparable massive rotator cuff tears

    International Nuclear Information System (INIS)

    Surgical treatment of massive rotator cuff tears is challenging for shoulder surgeons. The purpose of this study was to investigate both clinical outcomes and cuff integrity after tendon patch grafting using the long head of the biceps (LHB) tendon for irreparable massive rotator cuff tears. A short deltoid splitting approach was used to expose the torn cuff tendon stump. After tenodesis of the LHB tendon, its intraarticular portion was resected. If the size of the harvested tendon was smaller than that of the cuff defect, it was split into two layers. Then, the LHB tendon was sutured to the remnant cuff tendons and fixed to the footprint using the transosseous suture technique. A total of 14 patients (12 men, 2 women; average age 64 years) underwent this procedure. The average postoperative follow-up period was 28 months (range 12-51 months). Active elevation angle of the shoulder as well as the Japanese Orthopaedic Association (JOA) score were assessed before surgery and at the time of follow-up. Postoperative cuff integrity was assessed using T2-weighted magnetic resonance imaging (MRI). All cuff defects were successfully closed with this technique. Average active elevation angle improved from 69deg to 149deg. Total JOA score also improved from 54.7 points to 83.1 points. Thirteen shoulders showed no re-tearing on T2-weighted MRI; a minor discontinuity of the repaired cuff tendon was observed in the other shoulder. The LHB tendon is available in case tenodesis or tenotomy is needed. The resected tendon may be used as a graft for rotator cuff repair without any additional skin incision, which could reduce both the surgical invasion and the risk of infection. The LHB tendon patch grafting may be one of the useful options for surgical treatment of irreparable massive rotator cuff tears. (author)

    Full Text Available Background: Several tests to assist it in the diagnoses of rota-tor cuff impairment have been described in the literature but controversystill exists as to the accuracy of these tests. A study was therefore conducted to determine the reliability of the rotator cuff muscle tests (empty can, full can, lift off and external rotation as a diagnostic tool.Methodology: Fifty three patients experiencing shoulder pain were assessedusing manual muscle tests (empty can; full can; lift off and external rotationtests. Both pain and weakness were recorded using numerical scales adapted from tests performed by Itoi et al, (1999. These results were compared to ultrasonic diagnoses made by a surgeon. Informed consent was obtained and anonymity was ensured for all participants.Results: A test was false positive when ultrasonic diagnosis indicated no tear in the muscle (although oedema or calcification may have been present, but the manual muscle test was positive regarding pain and weakness. A test on the other hand was false negative when the ultrasonic diagnosis indicated a muscle tear but the manual muscle tests indicated no pain or muscle weakness. Reliability was tested using sensitivity and specificity tests. The sensitivity of all four tests was high (80%, but the specificity was low (20% to 40%, implying that a large number of false positive diagnoses can be made. The major contributors to the false positive results were sub-acromial sub-deltoid bursitis and a decreased acromio-humeral space. When considering pain alone for a positive result the correlation increased a  little, however, taking both pain and muscle weakness into account, the correlation increased even more.Conclusion: The manual muscle tests were not as reliable as expected, but concurrent pathologies may be the main factor influencing the results of the tests. The combination of muscle strength and pain could be recommendedas criteria for a positive test. The empty can and full can

    Objective: To determine the prevalence and clinical impact of rotator cuff tears in asymptomatic volunteers. Materials and Methods: Sonographic examinations of the shoulder of 212 asymptomatic individuals between 18 and 85 years old were performed by a single experienced operator. The prevalence and location of complete rotator cuff tears were evaluated. The clinical assessment was based on the Constant Score. Magnetic resonance imaging (MRI) of the shoulder was obtained in those patients where US showed rotator cuff pathology. Results: Ultrasound showed a complete rupture of the supraspinatus tendon in 6% of 212 patients from 56 to 83 years of age (mean: 67 years). MRI confirmed a complete rupture of the supraspinatus tendon in 90%. All patients reported no functional deficits, although strength was significantly lower in the patient group with complete supraspinatus tendon tear (P<0.01). Conclusion: There is a higher prevalence in older individuals of rotator cuff tendon tears that cause no pain or decrease in activities of daily living.

  7. Rotator cuff tears in children and adolescents: experience at a large pediatric hospital

    International Nuclear Information System (INIS)

    Prior literature, limited to small case series and case reports, suggests that rotator cuff tears are rare in adolescents. However, we have identified rotator cuff tears in numerous children and adolescents who have undergone shoulder MRI evaluation. The purpose of this study is to describe the prevalence and characteristics of rotator cuff tears in children and adolescents referred for MRI evaluation of the shoulder at a large pediatric hospital and to correlate the presence of rotator cuff tears with concurrent labral pathology, skeletal maturity and patient activity and outcomes. We reviewed reports from 455 consecutive non-contrast MRI and magnetic resonance arthrogram examinations of the shoulder performed during a 2-year period, and following exclusions we yielded 205 examinations in 201 patients (ages 8-18 years; 75 girls, 126 boys). Rotator cuff tears were classified by tendon involved, tear thickness (partial or full), surface and location of tear (when partial) and presence of delamination. We recorded concurrent labral pathology when present. Physeal patency of the proximal humerus was considered open, closing or closed. Statistical analysis was performed to evaluate for a relationship between rotator cuff tears and degree of physeal patency. We obtained patient activity at the time of injury, surgical reports and outcomes from clinical records when available. Twenty-five (12.2%) rotator cuff tears were identified in 17 boys and 7 girls (ages 10-18 years; one patient had bilateral tears). The supraspinatus tendon was most frequently involved (56%). There were 2 full-thickness and 23 partial-thickness tears with articular-side partial-thickness tears most frequent (78%). Insertional partial-thickness tears were more common (78%) than critical zone tears (22%) and 10 (43%) partial-thickness tears were delamination tears. Nine (36%) patients with rotator cuff tears had concurrent labral pathology. There was no statistically significant relationship between

    ABSTRACTA painful shoulder is a very common complaint among athletes, especially in the case of those in sports involving throwing. Partial lesions of the rotator cuff may be very painful and cause significant functional limitation to athletes' sports practice. The incidence of partial lesions of the cuff is variable (13-37%). It is difficult to make the clinical and radiological diagnosis, and this condition should be borne in mind in the cases of all athletes who present symptoms of rotator...

    The rotator cuff musculature imparts dynamic stability to the glenohumeral joint. In particular, the balance between the subscapularis anteriorly and the infraspinatus posteriorly, often referred to as the rotator cuff “force couple,” is critical for concavity compression and concentric rotation of the humeral head. Restoration of this anterior-posterior force balance after chronic, massive rotator cuff tears may allow for deltoid compensation, but no in vivo studies have quantitatively demon...

    Objectives: The teres minor has received increased attention in its role as a rotator cuff muscle, particularly in the setting of large infraspinatus tears. Studies have shown that it plays an important beneficial role after total (TSA) and reverse (RSA) shoulder arthroplasty, as well as in maintenance of function in the setting of infraspinatus wasting in patients with large rotator cuff tears. No study, however, has investigated how often teres minor hypertrophy occurs in a population of rotator cuff tears, whether it occurs in the absence of infraspinatus tearing, or whether it is a positive or negative prognostic indicator on outcomes after rotator cuff repair. The purpose of this study was to determine the prevalence of teres minor hypertrophy in a cohort of patients undergoing rotator cuff repair, and to determine its prognostic effect, if any, on outcomes after surgical repair. Methods: Over a 3 year period, all rotator cuff repairs performed in a single practice by 3 American Shoulder and Elbow Society (ASES) member surgeons were collected. One hundered forty-four patients who had preoperative and postoperative (ASES) outcomes (minimum 2 year), and preoperative Magnetic Resonance Imaging (MRI) were included in the study. All MRIs were evaluated for rotator cuff tear tendon involvement, tear size, and Goutallier changes of each muscle. In addition, occupational ratios were determined for the supraspinatus, infraspinatus, and teres minor muscles. Patients were divided into 2 groups, based upon whether they had teres minor hypertrophy or not, based on a previously established definition. A 2 way univariate ANOVA was used to determine the effect of teres minor hypertrophy(tear size by hypertrophy) and Goutallier changes(tear size by fatty infiltration) on ASES change scores(α=0.05) Results: Teres minor hypertrophy was a relatively common finding in this cohort of rotator cuff patients, with 51% of all shoulders demonstrating hypertrophy.

    Rotator cuff disease is a degenerative disorder that is a common, costly, and often debilitating, ranging in severity from partial thickness tear, which may cause pain, to total rupture, leading to loss in function. Currently, clinical diagnosis and determination of disease extent relies primarily on subjective assessment of pain, range of motion, and possibly X-ray or ultrasound images. The final treatment plan however is at the discretion of the clinician, who often bases their decision on personal experiences, and not quantitative standards. The use of ultrasound for the assessment of tissue biomechanics is established, such as in ultrasound elastography, where soft tissue biomechanics are measured. Few studies have investigated the use of ultrasound elastography in the characterization of musculoskeletal biomechanics. To assess tissue biomechanics we have developed a device, which measures the force applied to the underlying musculotendentious tissue while simultaneously obtaining the related ultrasound images. In this work, the musculotendinous region of the infraspinatus of twenty asymptomatic male organized baseball players was examined to access the variability in tissue properties within a single patient and across a normal population. Elastic moduli at percent strains less than 15 were significantly different than those above 15 percent strain within the normal population. No significant difference in tissue properties was demonstrated within a single patient. This analysis demonstrated elastic moduli are variable across individuals and incidence. Therefore threshold elastic moduli will likely be a function of variation in local-tissue moduli as opposed to a specific global value.

Postoperative rotator cuff tears can lead to pain, proximal humeral migration, and glenoid component loosening. The purpose of this paper was to evaluate the incidence of post-TSA rotator cuff tears or dysfunction in osteoarthritic patients. A systematic review of multiple databases was performed using preferred reporting items for systematic reviews and meta-analyses guidelines. Levels I-IV evidence clinical studies of patients with primary osteoarthritis with a minimum 2-year follow-up were included. Fifteen studies with 1259 patients (1338 shoulders) were selected. Student's t-tests were used with a significant alpha value of 0.05. All patients demonstrated significant improvements in motion and validated clinical outcome scores (P < 0.001). Radiographic humeral head migration was the most commonly reported data point for extrapolation of rotator cuff integrity. After 6.6 ± 3.1 years, 29.9 ± 20.7% of shoulders demonstrated superior humeral head migration and 17.9 ± 14.3% migrated a distance more than 25% of the head. This was associated with an 11.3 ± 7.9% incidence of postoperative superior cuff tears. The incidence of radiographic anterior humeral head migration was 11.9 ± 15.9%, corresponding to a 3.0 ± 13.6% rate of subscapularis tears. We found an overall 1.2 ± 4.5% rate of reoperation for cuff injury. Nearly all studies reported indirect markers of rotator cuff dysfunction, such as radiographic humeral head migration and clinical exam findings. This systematic review suggests that rotator cuff dysfunction following TSA may be more common than previously reported. IV, systematic review of Levels I-IV studies.

    Full Text Available OBJECTIVE: To compare the functional results from high and low-grade isolated partial lesions of the supraspinatus tendon of bursal and articular types, after arthroscopic treatment.METHODS: Sixty-four patients with isolated partial lesions of the supraspinatus tendon were evaluated. The mean length of follow-up was 76 months (range: 29-193. The mean age was 59 years (range: 36-82. The dominant side was affected in 44 patients (68.8%. There were 35 bursal lesions (54.7% and 29 articular lesions (45.3%. We used the Ellman classification and characterized the lesions as low or high-grade according to whether they affected less than or more than 50% of the tendon thickness, respectively. Debridement was performed in 15 patients (23.5%, repair without completing the lesion in 11 (17% and repair after completing the lesion in 38 (59.5%. The functional assessments on the patients were done using the Constant & Murley and UCLA scores.RESULTS: The mean Constant & Murley score among the patients with bursal lesions was 82.64 ± 6.98 (range: 59.3-99 and among those with articular lesions, 83.57 ± 7.58 (range: 66-95, while the mean UCLA score in the bursal lesions was 33.37 ± 2.85 (range: 21-35 and in the articular lesions, 32.83 ± 2.95 (range: 22-35.CONCLUSION: Videoarthroscopic treatment of partial lesions of the rotator cuff presents good or excellent results when the low-grade lesions are debrided and the high-grade lesions are completed and repaired. These results are maintained over the long term, with a high satisfaction rate and few complications.

    Objectives: Fifty percent of all athletes at the National Football League (NFL) Combine report having had a shoulder injury at some point during their playing career. Rotator cuff tears are rare injuries in young athletes, but an increasing incidence has been noted amongst competitive football players. It is unknown how pre-existing rotator cuff tears affect career longevity and performance of NFL athletes. In Combine athletes with pre-existing rotator cuff tears, knowledge of outcomes may help athletes and physicians manage expectations of draft potential, career length and performance. Methods: The written medical evaluations of prospective professional American football athletes from 2003-2011 during the NFL Combine were compiled and evaluated. All players were evaluated for the diagnosis of a pre-existing rotator cuff tear and stratified based on whether or not they underwent surgical intervention. Athletes with rotator cuff tears, who were selected in the NFL draft, were matched by age, position, year, and round drafted to control draftees without significant documented shoulder pathology. Career statistics, including a previously established “Performance Score,” were compiled. The continuous variables of each cohort were compared using a Student's t-test. A Chi Squared test was performed to analyze the categorical data. Statistical significance was accepted with a p-value < 0.05. Results: Between the years of 2003 and 2011, 2,965 consecutive athletes were evaluated. Forty-nine athletes were identified with a pre-existing rotator cuff tear; twenty-two of these athletes underwent surgical intervention for their tear and 27 were treated non-operatively. Those who attended the NFL Combine with a history of a rotator cuff tear were significantly less likely to be drafted than those without a previous injury (55.1% vs. 77.5% respectively, p = 0.002) (Table 1A). The 27 drafted athletes with pre-existing rotator cuff tears played significantly fewer years (4.3 vs

    Background: Despite advances in surgical treatment options, failure rates of rotator cuff repair have continued to range from 20% to 90%. Hence, there is a need for new repair strategies that provide effective mechanical reinforcement of rotator cuff repair as well as stimulate and enhance the intrinsic healing potential of the patient. The purpose of this study was to evaluate the extent to which augmentation of acute repair of rotator cuff tendons with a newly designed poly-L-lactide repair...

    The goal of this article is to consolidate the International Society of Arthroscopy, Knee Surgery & Orthopaedic Sports Medicine (ISAKOS) Upper Extremity Committee's (UEC's) current knowledge on rotator cuff disease and management, as well as highlight key unresolved issues. The rotator cuff is an anatomically complex structure important for providing glenohumeral function and stability as part of a closed chain system. Current consensus suggests rotator cuff injuries are most accurately diagnosed, at levels similar to diagnosis by magnetic resonance imaging, with a combination of cuff- and impingement-specific clinical tests. Updates in the understanding of acromion morphology, the insertional anatomy of the rotator cuff, and the role of suprascapular nerve release may require changes to current classification systems and surgical strategies. Although initial management focuses on nonoperative protocols, discussion continues on whether surgery for isolated impingement is clinically more beneficial than rehabilitation. However, clear indications have yet to be established for the use of single- versus double-row repair because evidence confirms neither is clinically efficacious than the other. Biceps tenodesis, however, in non-isolated cuff tears has proven more successful in addressing the etiology of shoulder pain and yields improved outcomes over tenotomy. Data reviewing the benefits of tendon transfers, shoulder prostheses, and mechanical scaffolds, as well as new research on the potential benefit of platelet-rich plasma, pluripotential stem cells, and gene therapies, will also be presented.

  19. Trabecular microstructure and surface changes in the greater tuberosity in rotator cuff tears

    International Nuclear Information System (INIS)

    Abstract Objective. When planning surgery in patients with rotator cuff tear, strength of bone at the tendon insertion and trabecular bone structure in the greater tuberosity are usually taken into consideration. We investigated radiographic changes in bone structure of the greater tuberosity in rotator cuff tears.Design. Twenty-two human cadaveric shoulders from subjects ranging from 55 to 75 years of age were obtained. The integrity of the rotator cuff was examined by sonography to determine if it is intact without any tear, or torn partially or completely. The humeral head was sectioned in 3 mm thick coronal slab sections and microradiographed. After digitization of the microradiographs and imaging processing with in-house semi-automated image processing software tools developed using software interfaces on a Sun workstation, the trabecular histomorphometrical structural parameters and connectivity in the greater tuberosity were quantified. The degenerative changes on the surface of the greater tuberosity were interpreted blindly by 2 independent readers.Results. Among the 22 shoulder specimens, the rotator cuff was found intact in 10 shoulders, partially in 7 and fully torn in 5. Statistically significant loss in apparent trabecular bone volume fraction, number of trabecular nodes, and number of trabecular branches, and a statistically significant increase in apparent trabecular separation and number of trabecular free ends were found in the greater tuberosity of the shoulders with tears. The loss was greater in association with full tear than in partial tear. Thickening of the cortical margin of the enthesis, irregularity of its surface, and calcification beyond the tidemark were observed in 2 (20%) shoulders with intact rotator cuff, in 6 (86%) shoulders with partial tear, and in 5 (100%) shoulders with full tear.Conclusions. Rotator cuff tears are associated with degenerative changes on the bone surface and with disuse osteopenia of the greater tuberosity

  20. Comparison of three-dimensional isotropic and conventional MR arthrography with respect to the diagnosis of rotator cuff and labral lesions: Focus on isotropic fat-suppressed proton density and VIBE sequences

    International Nuclear Information System (INIS)

    Aim: To compare the diagnostic accuracies of three-dimensional (3D) isotropic magnetic resonance arthrography (MRA) using fat-suppressed proton density (PD) or volume interpolated breath-hold examination (VIBE) sequences with that of conventional MRA for the diagnosis of rotator cuff and labral lesions. Materials and methods: Eighty-six patients who underwent arthroscopic surgery were included. 3D isotropic sequences were performed in the axial plane using fat-suppressed PD (group A) in 53 patients and using VIBE (group B) in 33 patients. Reformatted images were obtained corresponding to conventional images, and evaluated for the presence of labral and rotator cuff lesions using conventional and 3D isotropic sequences. The diagnostic performances of each sequence were determined using arthroscopic findings as the standard. Results: Good to excellent interobserver agreements were obtained for both 3D isotropic sequences for the evaluation of rotator cuff and labral lesions. Excellent agreement was found between two-dimensional (2D) and 3D isotropic MRA, except for supraspinatus tendon (SST) tears by both readers and for subscapularis tendon (SCT) tears by reader 2 in group B. 2D MRA and 3D isotropic sequences had high diagnostic performances for rotator and labral tears, and the difference between the two imaging methods was insignificant. Conclusions: The diagnostic performances of 3D isotropic VIBE and PD sequences were similar to those of 2D MRA

  1. Digital subtraction arthrography compared to ultrasound in lesions of the rotator cuff

    International Nuclear Information System (INIS)

    60 patients with suspected lesion of the rotator cuff were examined by digital subtraction arthrography and the results were compared to ultrasound. The dynamic study of digital subtraction arthrography visualised in 22 of 23 complete or incomplete cuff tears the exact location of the extravasation of the contrast medium. All diagnoses were confirmed by surgery. Problems of conventional arthrography were not seen by the digital method. (orig.)

  2. Long-Term MRI Findings in Operated Rotator Cuff Tear

    International Nuclear Information System (INIS)

    Purpose: To describe magnetic resonance imaging (MRI) findings at long-term follow-up after rotator cuff (RC) tear using standard MRI sequences without fat saturation. Material and Methods: Twenty-eight patients aged 55.8±7.6 underwent MRI examination 4.6±2.1 years after surgery for RC tear. Standard sequences in oblique coronal, oblique sagittal, and axial planes were obtained. The RC, including re-tears and tendon degeneration, was independently evaluated by two observers. Thickness of the supraspinatus tendon and narrowing of the subacromial space were measured. The clinical outcome was evaluated with the Constant score and compared with the MRI findings. Results: The RC tear was traumatic in 18 (64%) patients and degenerative in 10 (36%). At follow-up, 11 (39%) had normal RC tendons with good clinical outcome. Four (14%) patients had painful tendinosis without RC tear. A full-thickness RC tear was found in 7 (25%) patients and a partial tear in 6 (21%). In one patient with a full-thickness tear, and in two with partial tear, tendinosis was found in another of the RC tendons. The subacromial space was narrowed in 13 (46%) of the patients. A narrowing of the subacromial space correlated with re-tear (P<0.05). Conclusions: The RC may be evaluated with standard MRI sequences without fat saturation at long-term follow-up. A normal appearance of the RC is correlated with good clinical outcome, while re-tear and tendinosis are associated with pain

    Objective: To investigate the morphological changes of the roof of the subacromial bursa (SAB) and its involvement extent after rotator cuff tear. Methods: In the experimental group, the roof of SAB was obtained from 30 cases of rotator cuff tear both at the tear site and a site 2.5-3.0 cm distal to the tear site during rotator cuff repair. In the control group, the roof of SAB was obtained from the exposed site of recurrently dislocated shoulder or fractured humeral shaft of 8 cases.The specimens were stained with hematoxylin and eosin and observed under a transmission electron microscope. The cell number was quantitated through counting the bluestained nucleus in SAB with a computer image analysis system.Results: The number of cells increased significantly in the roof of SAB in the experimental group compared with that of the control group. However, no difference of the bursal reaction was found among the type of rotator cuff tear, the bursa thickness and the presence of fluid in the bursa. The great majority of cells were type B cells observed under the transmission electron microscope.Conclusions: The increase in cell number in the roof of SAB in the experimental group is a reactive increase rather than an inflammatory process and the involvement of SAB is not limited in extent. The change of the roof of SAB is a secondary reaction to the rotator cuff tear.

    Full Text Available Background: Surgical repair of massive rotator cuff tears is associated with less favorable clinical results and a higher retear rate than repair of smaller tears, which is attributed to irreversible degenerative changes of the musculotendinous unit. Materials and Methods: During the study period, 25 consecutive patients with a massive rotator cuff tear were enrolled in the study and the tears were repaired with an open suture anchor repair technique. Preoperative and postoperative clinical assessments were performed with the Constant score, the simple shoulder test (SST and a pain visual analog scale (VAS. At the final follow-up, rotator cuff strength measurement was evaluated and assessment of tendon integrity, fatty degeneration and muscle atrophy was done using a standardized magnetic resonance imaging protocol. Results: The mean follow-up period was 70 months. The mean constant score improved significantly from 42.3 to 73.1 points at the final follow-up. Both the SST and the pain VAS improved significantly from 5.3 to 10.2 points and from 6.3 to 2.1, respectively. The overall retear rate was 44% after 6 years. Patients with an intact repair had better shoulder scores and rotator cuff strength than those with a failed repair, and also the retear group showed a significant clinical improvement (each P<0.05. Rotator cuff strength in all testing positions was significantly reduced for the operated compared to the contralateral shoulder. Muscle atrophy and fatty infiltration of the rotator cuff muscles did not recover in intact repairs, whereas both parameters progressed in retorn cuffs. Conclusions: Open repair of massive rotator tears achieved high patient satisfaction and a good clinical outcome at the long-term follow-up despite a high retear rate. Also, shoulders with retorn cuffs were significantly improved by the procedure. Muscle atrophy and fatty muscle degeneration could not be reversed after repair and rotator cuff strength still did

  5. Rotator cuff disorders: How to write a surgically relevant magnetic resonance imaging report?

    Evaluation of rotator cuff is a common indication for magnetic resonance imaging (MRI) scanning of the shoulder. Conventional MRI is the most commonly used technique, while magnetic resonance (MR) arthrography is reserved for certain cases. Rotator cuff disorders are thought to be caused by a combination of internal and external mechanisms. A well-structured MRI report should comment on the relevant anatomic structures including the acromial type and orientation, the presence of os acromiale, acromio-clavicular degenerative spurs and fluid in the subacromial subdeltoid bursa. In addition, specific injuries of the rotator cuff tendons and the condition of the long head of biceps should be accurately reported. The size and extent of tendon tears, tendon retraction and fatty degeneration or atrophy of the muscles are all essential components of a surgically relevant MRI report. PMID:24976930

    Therapeutic options for the treatment of irreparable rotator cuff tears are fluent, are dependent on the patients' claims and demands and on the grade of the ongoing cuff tear arthropathy.A partial rotator cuff reconstruction with sufficient tenolysis combined with interval slide techniques to restore the anterior and posterior force couple may be indicated if there is no fatty degeneration > grade 3 of the rotator cuff muscles in a well-centered joint. The margin convergence technique with side-by-side adaptation of the tendon limbs may reduce the load on the reconstructed tendons.The role of the suprascapular nerve, which can probably be constricted by the retracted rotator cuff, and its therapy has not been completely clarified. When distinct symptoms are present neurolysis may be reasonable.Tendon transfers can be indicated in a cooperative patient grade II according to Hamada with the loss of active external rotation but performable active flexion. For posterosuperior tears the latissimus dorsi or recently the teres major tendon transfer to the rotator cuff footprint may be appropriate. For nonreconstructable anterosuperior tears a partial transfer of the pectoralis major tendon is possible.Careful subacromial debridement combined with biceps tenotomy and a cautious or reversed decompression may reduce the pain temporarily without having an influence on active motion until with the loss of active elevation the indication for a reversed shoulder arthroplasty is reached.In the mean time, absorbable subacromial spacers may re-center the humeral head, but the effectiveness of this therapy on clinical outcome should be analyzed in further studies.

    Although excessive tension of the upper trapezius (UT) is thought to contribute to rotator cuff tendinopathy, no study examined UT tension in athletes with and without rotator cuff tendinopathy. Here we used UT shear modulus measured using ultrasound shear wave elastography as an index of muscle stiffness/tension. The aims of this study were twofold: 1) to determine whether the UT muscle shear modulus is altered in athletes with rotator cuff tendinopathy compared to asymptomatic athletes, and 2) to detect optimal cut-off points of UT shear modulus in identifying athletes with rotator cuff tendinopathy. Forty-three male volleyball players (17 asymptomatic and 26 with rotator cuff tendinopathy, mean age = 22.9±3.5 years) participated in the study. UT shear modulus was quantified during active arm holding at 30° and 60° of shoulder abduction and passive arm positioning at 0°, 30° and 60° of shoulder abduction. During the active tasks, the UT shear modulus was higher in athletes with rotator cuff tendinopathy than the asymptomatic athletes (p = 0.002), regardless the arm position. During the passive tasks, athletes with rotator cuff tendinopathy exhibited a higher UT shear modulus than asymptomatic athletes only at 0° of shoulder abduction (13.0±2.5 kPa vs 10.2±1.8 kPa, p = 0.001). When considering the active task, an optimal cut-off shear modulus of 12.0 kPa at 30° of shoulder abduction (sensitivity = 0.84, specificity = 0.57, AUC = 0.757, p = 0.008) and 9.5 kPa at 60° of shoulder abduction (sensitivity = 0.88, specificity = 0.67, AUC = 0.816, p = 0.002) was detected. When considering the passive task at 0° of shoulder abduction, a cut-off of 12.2 kPa was found (sensitivity = 0.73, AUC = 0.817, p = 0.001). Findings from the present study show that monitoring passive and active UT muscle shear modulus may provide important information for the prevention/rehabilitation of rotator cuff tendinopathy.

    Corticosteroids (CS) or hyaluronic acid (HA) is used in subacromial injection for the conservative treatment of rotator cuff tears (RCT); this study addresses the question of how CS and HA affect the tendon tissue and fibroblasts in vitro and in rats. Cell proliferation assays were performed in human tendon fibroblasts from RCT. Rats underwent surgery to create RCT, and the surgical sites were injected with CS or HA. The rotator cuff tendons were subjected to biomechanical testing, microscopic and immunohistochemical analysis of proliferating cell nuclear antigen (PCNA), and ultrastructural analysis. Cell proliferation was significantly decreased with CS in vitro (p site. PMID:26174562

    Calcific tendinitis is a painful shoulder disorder characterised by either single or multiple deposits in the rotator cuff tendon. Although the disease subsides spontaneously in most cases, a subpopulation of patients continue to complain of pain and shoulder dysfunction and the deposits do not show any signs of resolution. Although several treatment options have been proposed, clinical results are controversial and often the indication for a given therapy remains a matter of clinician choice. Herein, we report on the current state of the art in the pathogenesis, diagnosis and treatment of calcific tendinitis of the rotator cuff. PMID:26163832

  13. IMAGING OF ROTATOR CUFF PATHOLOGY- IS ULTRASOUND AS GOOD AS MRI

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Aim of this study is to compare the diagnostic accuracy of ultrasound versus MRI in detecting rotator cuff pathology. Rotator cuff pathology involves group of disorder, which progresses from bursitis to tendinitis to partial tear and full thickenss tear. The most commonly affected tendon is the supraspinatus tendon. In our prospective study of 35 patients as initial ultrasound was followed by MRI sensitivity, specificity and accuracy for diagnosis of full thickness tear of supraspinatus when USG was compared to MRI was 100%, whereas sensitivity, specificity and accuracy of diagnosing partial thickness tear using ultrasound compared to MRI are 100%, 78% and 84%. There is no significant p value difference on comparing ultrasound with MRI on detecting tears. Ultrasound and MRI showed almost similar diagnostic accuracy in associated findings like tendon retraction, muscle atrophy, bursal effusion. Ultrasound also has additional value of dynamic evaluation, which is useful in evaluating subacromial and subcoracoid impingement. Modality choice for the evaluation of rotator cuff pathology should be based on several factors like availability, patient preference and clinical information being sought. The high resolution sonography is an attractive screening modality for rotator cuff in patients presenting with painful shoulder. A well performed ultrasound examination in most cases obviates the need for more invasive diagnostic tests like arthrography and cumbersome and expensive MRI examinations.

    We describe a case of inferior glenohumeral subluxation or drooping shoulder secondary to acute calcific tendinitis of the rotator cuff. The various etiologies of drooping shoulder and the specific causes determining glenohumeral widening in our report are discussed. The importance in recognizing this uncommon complication of a common abnormal finding and correction by aspiration is stressed. (orig.)

    Objectives: Despite advances in the surgical techniques of rotator cuff repair (RCR), the management of massive rotator cuff tears in shoulders without glenohumeral arthritis poses a difficult problem for surgeons. Failure of massive rotator cuff repairs range from 20-90% at one to two years postoperatively using arthrography, ultrasound, or magnetic resonance imaging. Additionally, there are inconsistent outcomes reported with debridement alone of massive rotator cuff tears as well as limitations seen with other current methods of operative intervention including arthroplasty and tendon transfers. The purpose of this prospective, comparative study was to determine if the repair of massive rotator cuff tears using an interposition porcine acellular dermal matrix xenograft improves subjective function, pain, range of motion, and strength at greater than two years follow-up. To our knowledge, this is the largest prospective series reporting outcomes of using porcine acellular dermal matrix xenograft as an interposition graft. Methods: Thirty-seven patients (37 shoulders) with an average age of 66 years (range 51-80 years) were prospectively followed for 33 months (range 23-48) following massive RCR using porcine acellular dermal matrix interposition xenograft. Subjective outcomes were measured using the Visual Analog Scale (VAS) pain score (0-10, 0 = no pain), Modified American Shoulder and Elbow Score (M-ASES), and Short-Form12 (SF-12) scores. Preoperative and postoperative objective outcome measures included active range of motion and supraspinatus and infraspinatus manual muscle strength. Postoperative outcome measures included quantitative muscle strength using a dynamometer and static and dynamic ultrasonography to assess the integrity of the repair. Results: Average VAS pain score decreased from 4.5 to 1.1 (Pacellular dermal matrix xenografts, patients had significant improvement in pain, range of motion, strength and reported good subjective function based on

    Humeral tuberosity cysts are a common finding, with previous reports suggesting they are related to rotator cuff tear or aging. The aim of this study was to investigate the characteristics of cysts in the tuberosities of the humeral head and their relationship with rotator cuff tear and age. Shoulder MR arthrograms were reviewed in 120 consecutive patients - 83 males (mean age 38.0, range 19-59 years) and 37 females (mean age 41.2, range 15-59 years). Patients were referred for investigation of a variety of conditions, and instability was suspected in only a minority of cases. MR was performed before and after direct arthrography with 0.01% solution of gadolinium. Cysts were defined as well-demarcated circular/ovoid foci in two planes that demonstrated high signal on pre-arthrographic T2W sequences. Location, size and numbers of cysts and post-arthrographic enhancement were documented, along with the location of rotator cuff tears, if present. Cysts in the tuberosities of the humerus were identified in 84 patients (70%), and were seen seven times more frequently in the posterior aspect of the greater tuberosity than anteriorly. Most cysts (94%) demonstrated communication with the joint post-arthrogram. Rotator cuff tears were present in 36 patients, and 79% of all tears occurred in supraspinatus tendon. There was no significant difference in the occurrence of cysts between patients older or younger than age 40 or between genders, but rotator cuff tears were seen significantly more often in the older age group (p<0.01). Tuberosity cysts and rotator cuff tears did not appear to be related (p=0.55). However, whilst this lack of association was quite obvious posteriorly (p=0.84), the trend in the anterior aspect of the greater tuberosity is not as clear (p=0.14). Humeral cysts are most often located in the posterior aspect of the greater tuberosity, communicate with the joint space and, in this location, are not related to aging or rotator cuff tear. (orig.)

    Full Text Available Background: Rotator cuff problems are frequently seen by orthopedic surgeons and accurate diagnosis is essential for appropriate management. Value of the clinical assessment of a shoulder is often limited, therefore, imaging studies have important implications in the management of rotator cuff pathologies. Aim: The purpose of this retrospective study is to compare the accuracy of ultrasonography (US and magnetic resonance imaging (MRI for detection of full-thickness rotator cuff tears. Materials and Methods: We reviewed 91 consecutive cases of shoulder arthroscopy and open rotator cuff repair, who had undergone preoperative investigation in the form of either an ultrasound or MRI. Thirty-six patients had an ultrasound and 55 had an MRI for their affected shoulders. We compared the accuracy of US and MRI for detection of full-thickness rotator cuff tears, using the operative findings as the ′gold standard′. Data regarding a supraspinatus tear was assessed for the purpose of this study. Results: Ultrasonography correctly diagnosed 15 out of 17 tears (sensitivity of 0.88. There were 17 true-negative and two false-positive ultrasounds (specificity of 0.89. MRI accurately identified 33 of the 36 tears (sensitivity of 0.91. There were 16 true-negative and three false-positive tears on MRI (specificity of 0.84. The positive predictive value (PPV was 88% for US and 92% for MRI. The negative predictive value (NPV was 89% for US and 84% for MRI. The overall accuracy of the ultrasound was 88.89% (95% confidence interval (CI = 74.09 to 96.18 as compared to 89.09% (95% CI = 77.82% to 95.26% for the MRI. Conclusion: Full-thickness rotator cuff tears can be identified using ultrasound and MRI with comparable accuracy. US being a dynamic study and better tolerated by the patient, can therefore be used as the first-line investigation for rotator cuff tear, where appropriate skills are available to reduce the waiting time and cost of investigation.

    To describe the magnetic resonance imaging (MRI) appearances of tears of the deltoid muscle and tendon in patients with rotator cuff tears and without a prior history of shoulder surgery. Deltoid tears diagnosed on MR examinations were prospectively recorded between February 2003 through June 2004. The images of these patients were then retrospectively reviewed to determine the location of the deltoid tear, the presence of rotator cuff tears, tendon retraction, muscle atrophy, degree of humeral head subluxation, bony erosive changes involving the undersurface of the acromion, and the presence of edema or fluid-like signal intensity in the deltoid muscle and overlying subcutaneous tissues. There were 24 (0.3%) patients with deltoid tears; nine men and 15 women. The age range was 54 to 87 (average 73) years. The right side was involved in 20 cases, and the left in four cases. Fifteen patients had full thickness and nine had partial thickness tears of the deltoid. Shoulder pain was the most common presenting symptom. The physical examination revealed a defect in the region of the deltoid in two patients. Nineteen patients had tears in the muscle belly near the musculotendinous junction, and five had avulsion of the tendon from the acromial origin. Full thickness rotator cuff tears were present in all of the patients, and 22 patients had associated muscle atrophy. Subcutaneous edema and fluid-like signal was present in 15 patients. Tears of the deltoid muscle or tendon is an unusual finding, but they can be seen in patients with chronic massive rotator cuff tears. Partial thickness tears tend to involve the undersurface of the deltoid muscle and tendon. Associated findings such as intramuscular cyst or ganglion in the deltoid muscle belly and subcutaneous edema or fluid-like signal overlying the deltoid in a patient with a rotator cuff tear should raise the suspicion of a deltoid tear.

    Injuries of the rotator cuff and the biceps tendon demonstrate different patterns, which can be recognized clinically and radiologically. These patterns are impingement syndrome with additional trauma, isolated trauma of the rotator cuff and shoulder dislocation causing rotator cuff tears. Furthermore, it is clinically crucial to evaluate the extent of a rotator cuff injury. Magnetic resonance imaging (MRI) is the modality of choice to differentiate these patterns. (orig.)

    We conducted a study to assess the impact of tear location on functional outcomes in high-grade partial-thickness rotator cuff tears (PTRCTs) after arthroscopic completion and repair. Retrospectively, we evaluated the preoperative and postoperative findings of 60 patients who underwent arthroscopic completion and repair of Ellman grade 3 partial-thickness tears of the supraspinatus. The 60 patients were grouped by tear subtype (20 articular, 20 bursal, 20 intratendinous) as identified by preoperative imaging and confirmed at time of surgery. After surgery, the 3 subtypes showed similar significant (P < .001) improvements in American Shoulder and Elbow Surgeons scores (articular, 46.9, 85.1; bursal, 44.3, 80.3; intratendinous, 43.6, 86.1), Constant scores (articular, 54.3, 79.4; bursal, 49.9, 75.0; intratendinous, 56.8, 80.9), and visual analog scale scores (articular, 5.1, 1.2; bursal, 5.8, 1.6; intratendinous, 6.0, 1.2). Our study findings validate use of the current algorithm for Ellman grade 3 PTRCTs of the supraspinatus and advocate their completion and repair, regardless of tear location. PMID:27552462

    Full Text Available Management  of  patients  with  rotator  cuff  myofascial  pain syndrome varies  and  successful  intervention  is  dependent  on accurate assessment. The aim of this case report is to show the importance of accurate assessment  and  clinical  reasoning  in  the  physiotherapeutic management  of a  patient  suffering  from  ante-cubital  and  anterior shoulder  pain.  The  patient was  referred  for  physiotherapy  after proving refractory  to  treatment  with  non-steroidal anti-inflammatory medication. The physiotherapist diagnosed a rotator cuff myofascial pain syndrome and treatment proceeded on that basis. Treatment consisted of twitch-obtaining dry needling, myofascial release and exercise therapy.  The result was a change in the harryman rotator cuff functional Assessment Scale score from 22/52 to 43/52 over eight treatments. Strength was regained and subjective pain report on the visual rating scale was improved to 1/10. The case study highlights the importance of accurate assessment and consideration of alternative myofascial sources for pain even in circumstances which initially seem trauma related. Precise diagnosis of the cause - in this case rotator cuff myofascial pain syndrome – will result in effective treatment being administered.

    Chomiak, J

    1997-01-01

    The author presents his short-term experience with reconstruction operations in ruptures of the rotator cuff which were performed according to principles accepted at present in twenty five patients (26 shoulders) during 1993-1996. Men predominated in the group (16 men) and the majority of patients were in the age bracket from 50-70 years. The follow-up period was 6-36 months. Massive ruptures with a lesion of the cuff exceeding 5 cm (10 times) predominated, followed by ruptures with a lesion under 2 cm (9 times). In the majority of patients the operatoin was made using the Kessel-Gschwend approach. After anterior acromionplasty the tendons of the cuff were released and fixed into the ridge between the articular area of the head of the joint and the large tubercle. The operated extremity was fixed on an abduction splint for 4-6 weeks and this was followed by controlled rehabilitation for 1-2 months. According to Constant's functional score excellent results were achieved in 31 % of the operated patients, a satisfactory result in 11 % and an unsatisfactory result in 23 % of the operated patients. The presented results are consistent above all with the subjective evaluation and evaluation of pain resulting from subacromial decompression. The functional result is consiostent with the achieved extent of mobility of the shoulder. In the majority of patients however marked restriction of strength in abduction persists due to muscular hypotrophy asa result of predominating inveterate massive ruptures. Unsatisfactory results were recorded in six patients in conjunction with the following circumstances: reoperation in the subacromial space, mechanical failure of the suture, deep infection in diabetes mellitus, operation of an occupational injury with attempted compensation and refractory cervicobrachial syndrome with an impact on the shoulder joint. From this initial experience ensues that reconstructions of the rotator cuff are successful provided the indication is correct

  16. Evaluation of muscular activity duration in shoulders with rotator cuff tears using inertial sensors and electromyography

    International Nuclear Information System (INIS)

    Shoulder disorders, including rotator cuff tears, affect the shoulder function and result in adapted muscle activation. Although these adaptations have been studied in controlled conditions, free-living activities have not been investigated. Based on the kinematics measured with inertial sensors and portable electromyography, the objectives of this study were to quantify the duration of the muscular activation in the upper trapezius (UT), medial deltoid (MD) and biceps brachii (BB) during motion and to investigate the effect of rotator cuff tear in laboratory settings and daily conditions. The duration of movements and muscular activations were analysed separately and together using the relative time of activation (TEMG/mov). Laboratory measurements showed the parameter’s reliability through movement repetitions (ICC > 0.74) and differences in painful shoulders compared with healthy ones (p < 0.05): longer activation for UT; longer activation for MD during abduction and tendency to shorter activation in other movements; shorter activation for BB. In daily conditions, TEMG/mov for UT was longer, whereas it was shorter for MD and BB (p < 0.05). Moreover, significant correlations were observed between these parameters and clinical scores. This study thus provides new insights into the rotator cuff tear effect on duration of muscular activation in daily activity. (paper)

    Xiaoxi Ji

    Full Text Available The major concern of using a large animal model to study rotator cuff repair is the high rate of repair retears. The purpose of this study was to test a non-weight-bearing (NWB canine model for rotator cuff repair research.First, in the in vitro study, 18 shoulders were randomized to 3 groups. 1 Full-width transections repaired with modified Mason-Allen sutures using 3-0 polyglactin suture, 2 Group 1 repaired using number 2 (#2 polyester braid and long-chain polyethylene suture, and 3 Partial-width transections leaving the superior 2 mm infraspinatus tendon intact without repair. In the in vivo study of 6 dogs, the infraspinatus tendon was partially transected as the same as the in vitro group 3. A radial neurectomy was performed to prevent weight bearing. The operated limb was slung in a custom-made jacket for 6 weeks.In the in vitro study, mean ultimate tensile load and stiffness in Group 2 were significantly higher than Group 1 and 3 (p<0.05. In the in vivo study, gross inspection and histology showed that the preserved superior 2-mm portion of the infraspinatus tendon remained intact with normal structure.Based on the biomechanical and histological findings, this canine NWB model may be an appropriate and useful model for studies of rotator cuff repair.

    2011-01-01

    Background and Purpose: Golf is a popular sport played by hundreds of thousands of individuals of all ages and of varying skill levels. An orthopedic or sports-related injury and/or surgery may limit an individual's sport participation, require him/her to complete a course of rehabilitation, and initiate (or resume) a sport-specific training program. Unlike the availability of evidence to guide postsurgical rehabilitation and sport-specific training of athletes from sports other than golf, there have only been two reports describing outcomes after surgery and for golfers. The purpose of this case report is to present a post-rehabilitation return to sport-training program for a recreational golfer 11-months after a rotator cuff repair. Case Description: The subject, a 67-year old female, injured her right shoulder requiring a rotator cuff repair 11-months prior to her participation in a golf fitness training program. The subject participated in six training sessions over seven week period consisting of general strengthening exercises (including exercises for the rotator cuff), exercises for the core, plyometrics, and power exercises. Outcomes: The subject made improvements in power and muscular endurance of the core. She was able to resume golf at the completion of the training program. Discussion: The subject was able to make functional improvements and return to golf after participation in a comprehensive strength program. Additional studies are necessary to improve program design for golfers who wish to return to sport after shoulder surgery. PMID:22163096

    Full Text Available The time-course covered by the original definition of scapulo-humeral periarthritis suggested by Duplay through the more recent term of subacromial impingement syndrome coined by Neer, follows the identification of the pathogenetic mechanisms leading to chronic subacromial impingement and degenerative tears of the rotator cuff. The Authors recall the functional-anatomic development evolution of the shoulder and the disequilibrium between the depressor and the elevator muscles which may promote the chronic friction against the acromion. However, the actual pathogenesis of the impingement still remains controversial. We evaluated 134 patients (81F, 53M, mean age 56.4 years with chronic subacromial impingement syndrome. In 92 cases (69% non traumatic tears of the rotator cuff were also present as confirmed by ultrasonography in 94 cases, CT in18 cases and magnetic resonance in 102 cases. The different tear patterns of the rotator cuff were classified as suggested by Ellman (L shaped, L reverse, triangular, trapezoidal and massive with retraction and clinical results were analysed following Sahlstrand clinical criteria and Costant numerical scale. According to the anatomical damage, patients were divided into those with impingement without severe cuff tendinopathy (42 cases, those with rotator cuff tears without loss of motion of the shoulder (32 cases and those with cuff tears and loss of active motion (60 cases. The different surgical techniques and rehabilitation procedures after surgery are also reported. After a mean follow-up of 1.3 years (range 8 months - 2 years, good or excellent results were obtained in 91% of the patients without rotator cuff tears, in 87% of the patients with tears but without loss of motion and in 75% of the cases with loss of active motion. Our data demonstrate that in the majority of patients with chronic impingement syndrome and rotator cuff tears, surgical treatment shows high success rates. When surgery is

  1. Magnetic Resonance Imaging of Rotator Cuff Tears in Shoulder Impingement Syndrome

    International Nuclear Information System (INIS)

    Shoulder joint is a common site of musculoskeletal pain caused, among other things, by rotator cuff tears due to narrowing of subacromial space, acute trauma or chronic shoulder overload. Magnetic resonance imaging (MRI) is an excellent modality for imaging of soft tissues of the shoulder joint considering a possibility of multiplanar image acquisition and non-invasive nature of the study. The aim of this study was to evaluate the prevalence of partial and complete rotator cuff tears in magnetic resonance images of patients with shoulder impingement syndrome and to review the literature on the causes and classification of rotator cuff tears. We retrospectively analyzed the results of 137 shoulder MRI examinations performed in 57 women and 72 men in Magnetic Resonance facility of the Department of Radiology and Diagnostic Imaging at the St. Jadwiga the Queen Regional Hospital No. 2 in Rzeszow between June 2010 and February 2013. Examinations were performed using Philips Achieva 1.5T device, including spin echo and gradient echo sequences with T1-, T2- and PD-weighted as well as fat saturation sequences in transverse, frontal and sagittal oblique planes. Patients were referred from hospital wards as well as from outpatient clinics of the subcarpathian province. The most frequently reported injuries included partial supraspinatus tendon tear and complete tearing most commonly involved the supraspinatus muscle tendon. The smallest group comprised patients with complete tear of subscapularis muscle tendon. Among 137 patients in the study population, 129 patients suffered from shoulder pain, including 57 patients who reported a history of trauma. There was 44% women and 56% men in a group of patients with shoulder pain. Posttraumatic shoulder pain was predominantly reported by men, while women comprised a larger group of patients with shoulder pain not preceded by injury. Rotator cuff injury is a very common pathology in patients with shoulder impingement syndrome

  2. Diagnosis of rotator cuff tears using 3-Tesla MRI versus 3-Tesla MRA: a systematic review and meta-analysis

    To compare the diagnostic accuracy of magnetic resonance imaging (MRI), 2-dimensional magnetic resonance arthrogram (MRA) and 3-dimensional isotropic MRA in the diagnosis of rotator cuff tears when performed exclusively at 3-T. A systematic review was undertaken of the Cochrane, MEDLINE and PubMed databases in accordance with the PRISMA guidelines. Studies comparing 3-T MRI or 3-T MRA (index tests) to arthroscopic surgical findings (reference test) were included. Methodological appraisal was performed using QUADAS 2. Pooled sensitivity and specificity were calculated and summary receiver-operating curves generated. Kappa coefficients quantified inter-observer reliability. Fourteen studies comprising 1332 patients were identified for inclusion. Twelve studies were retrospective and there were concerns regarding index test bias and applicability in nine and six studies respectively. Reference test bias was a concern in all studies. Both 3-T MRI and 3-T MRA showed similar excellent diagnostic accuracy for full-thickness supraspinatus tears. Concerning partial-thickness supraspinatus tears, 3-T 2D MRA was significantly more sensitive (86.6 vs. 80.5 %, p = 0.014) but significantly less specific (95.2 vs. 100 %, p < 0.001). There was a trend towards greater accuracy in the diagnosis of subscapularis tears with 3-T MRA. Three-Tesla 3D isotropic MRA showed similar accuracy to 3-T conventional 2D MRA. Three-Tesla MRI appeared equivalent to 3-T MRA in the diagnosis of full- and partial-thickness tears, although there was a trend towards greater accuracy in the diagnosis of subscapularis tears with 3-T MRA. Three-Tesla 3D isotropic MRA appears equivalent to 3-T 2D MRA for all types of tears. (orig.)

    Objective To evaluate the evolution of the functional results from CTA® hemiarthroplasty for surgically treating degenerative arthroplathy of the rotator cuff, with a mean follow-up of 5.4 years. Methods Eighteen patients who underwent CTA® partial arthroplasty to treat degenerative arthroplathy of the rotator cuff between April 2007 and June 2009 were reevaluated, with minimum and mean follow-ups of 4.6 years and 5.4 years, respectively. Pre and postoperative parameters for functionality and patient satisfaction were used (functional scale of the University of California in Los Angeles, UCLA). All the patients underwent prior conservative treatment for 6 months and underwent surgical treatment because of the absence of satisfactory results. Patients were excluded if they presented any of the following: previous shoulder surgery; pseudoparalysis; insufficiency of the coracoacromial arch (type 2 B in Seebauer's classification); neurological lesions; or insufficiency of the deltoid muscle and the subscapularis muscle. Results With a mean follow-up of 5.4 years, 14 patients considered that they were satisfied with the surgery (78%); the mean range of joint motion for active elevation improved from 55.8° before the operation to 82.0° after the operation; the mean external rotation improved from 18.9° before the operation to 27.3° after the operation; and the mean medial rotation remained at the level of the third lumbar vertebra. The mean UCLA score after the mean follow-up of 5.4 years was 23.94 and this was an improvement in comparison with the preoperative mean and the mean 1 year after the operation. Conclusion The functional results from CTA® hemiarthroplasty for treating rotator cuff arthroplasty in selected patients remained satisfactory after a mean follow-up of 5.4 years. PMID:26229938

    Degradation and injury of the rotator cuff is one of the most common diseases of the shoulder among the general population. In orthopedic injuries, rotator cuff disease is only second to back pain in terms of overall reduced quality of life for patients. Clinically, this disease is managed via pain and activity assessment and diagnostic imaging using ultrasound and MRI. Ultrasound has been shown to have good accuracy for identification and measurement of rotator cuff tears. In our previous work, we have developed novel, real-time techniques to biomechanically assess the condition of the rotator cuff based on Musculoskeletal Ultrasound. Of the rotator cuff tissues, supraspinatus is the first that sees degradation and is the most commonly affected. In our work, one of the challenges lies in effectively segmenting and characterizing the supraspinatus. We are exploring the possibility of using curvelet transform for improving techniques to segment tissue in ultrasound. Curvelets have been shown to give optimal multi-scale representation of edges in images. They are designed to represent edges and singularities along curves in images which makes them an attractive proposition for use in ultrasound segmentation. In this work, we present a novel approach to the possibility of using curvelet transforms for automatic edge and feature extraction for the supraspinatus.

    Full Text Available Abstract Background Shoulder dysfunction is common and pathology of the rotator cuff tendons and subacromial bursa are considered to be a major cause of pain and morbidity. Although many hypotheses exist there is no definitive understanding as to the origin of the pain arising from these structures. Research investigations from other tendons have placed intra-tendinous neovascularity as a potential mechanism of pain production. The prevalence of neovascularity in patients with a clinical diagnosis of rotator cuff tendinopathy is unknown. As such the primary aim of this pilot study was to investigate if neovascularity could be identified and to determine the prevalence of neovascularity in the rotator cuff tendons and subacromial bursa in subjects with unilateral shoulder pain clinically assessed to be rotator cuff tendinopathy. The secondary aims were to investigate the association between the presence of neovascularity and pain, duration of symptoms, and, neovascularity and shoulder function. Methods Patients with a clinical diagnosis of unilateral rotator cuff tendinopathy referred for a routine diagnostic ultrasound (US scan in a major London teaching hospital formed the study population. At referral patients were provided with an information document. On the day of the scan (on average, at least one week later the patients agreeing to participate were taken through the consent process and underwent an additional clinical examination prior to undergoing a bilateral grey scale and colour Doppler US examination (symptomatic and asymptomatic shoulder using a Philips HDI 5000 Sono CT US machine. The ultrasound scans were performed by one of two radiologists who recorded their findings and the final assessment was made by a third radiologist blinded both to the clinical examination and the ultrasound examination. The findings of the radiologists who performed the scans and the blinded radiologist were compared and any disagreements were resolved

    The purpose of this paper was to evaluate if short volumetric interpolated breath-hold examination (VIBE) sequences can be used as a substitute for T1-weighted with fat saturation (T1-FS) sequences when performing magnetic resonance (MR) arthrography to diagnose rotator cuff tears. Eighty-two patients underwent direct MR arthrography of the shoulder joint using VIBE (acquisition time of 13 s) and T1-FS (acquisition time of 5 min) sequences in the axial and paracoronal plane on a 1.0-T MR unit. Two radiologists scored rotator cuff tendons on VIBE and T1-FS images separately as normal, small/large partial thickness and full thickness tears with or without geyser sign. T1-FS sequences were considered the gold standard. Surgical correlation was available in a small sample. Sensitivity, specificity, and positive and negative predictive values of VIBE were greater than 92% for large articular-sided partial thickness and full thickness tears. For detecting fraying and articular-sided small partial thickness tears, these parameters were 55%, 94%, 94%, and 57%, respectively. The simple kappa value was 0.76, and the weighted kappa value was 0.86 for agreement between T1-FS and VIBE scores. All large partial and full thickness tears at surgery were correctly diagnosed using VIBE or T1-FS MR images. Fast MR arthrography of the shoulder joint using VIBE sequences showed good concordance with the classically used T1-FS sequences for the appearance of the rotator cuff, in particular for large articular-sided partial thickness tears and for full thickness tears. Due to its very short acquisition time, VIBE may be especially useful when performing MR arthrography in claustrophobic patients or patients with a painful shoulder. (orig.)

    Full Text Available Introduction: The objective of this study was to assess a long-term clinical effect of Prolotherapy on chronic symptomatic rotator cuff tendinopathy.Methods: We conducted a retrospective, uncontrolled study in the outpatient setting with 12 months follow-up. Adults diagnosed clinically and radiologically with rotator cuff tendinopathy that has been persisting for a minimum of six months were included. Patients received 15% extra-articular and 25% intra-articular hyperosmolar dextrose injections, repeated at weeks 5, 9, 13, 17 and 21. Primary outcome measure was validated Shoulder Pain and Disability Index (SPADI. Secondary outcome measure was validated visual pain analogue scale (VAS 0-10. The third outcome measures were patient’s satisfaction with Prolotherapy and adverse reactions after injections.Results: Twenty-one patients, 14 male and 7 female were treated with 6 sessions of hyperosmolar dextrose Prolotherapy repeated every 4 weeks. Average SPADI before starting the treatment was 73.995 ± 13.6, while 12 months after completed treatment was 20.84 ± 26.03 (P< 0.0001. Average VAS score before starting the treatment was 8.14 ± 1.2, while 12 months after completed treatment was 2.29 ± 2.8 (P<0.0001. Out of 21 patients, 18 (85.71% would recommend Prolotherapy to other people with the similar condition, and no one participant reported any side effect that was not resolved within one week after the treatment.Conclusion: Hyperosmolar dextrose Prolotherapy may result in significant reduction of pain and disability index in adult patients with chronic rotator cuff tendinopathy, without eliciting long-lasting side effects. Results of this pilot study need to be validated in prospective controlled randomized trials.

    Full Text Available The purpose of this study was to evaluate the outcome of deltoid muscle flap transfer for the treatment of irreparable rotator cuff tears. In a retrospective study 20 consecutive patients were evaluated. The index procedure took place between 2000 and 2003. Fifteen patients were male, mean age was 62 years. Inclusion criterion was a rotator cuff defect Bateman grade IV. Exclusion criteria were smaller defects, shoulder instability and fractures of the injured shoulder. An open reconstruction with acromioplasty and a pedicled delta flap was performed. Follow up period was mean 42 months. Follow-up included clinical examination, Magnetic Resonance Imaging (MRI and the Constant and Simple (CS shoulder tests. According to the Constant shoulder test the results were good in 13 patients, fair in 5 and unsatisfactory in 2. The pre-operative Constant Score improved from mean 25.7 points (±5.3 to 72.3 (±7.8 at follow-up. The mean values for the subcategories of CS increased significantly from 3.9 to 14.4 points for pain and from 4.2 to 15.9 points for activities daily routine (p0.05. Results of the Simple Shoulder Test showed a significant increase of the mean values from pre-operative 4.3 to 14.7 points post-operatively. MRI showed a subacromial covering of the defect in all cases, all flaps where intact on MRI but always the flap showed marked fatty degeneration. In conclusion, the delta flap is a simple method for the repair of large defects of the rotator cuff leading to satisfying medium results.

    Full Text Available The long head of the biceps tendon (LHBT is an anatomic structure commonly involved in painful shoulder conditions as a result of trauma, degeneration, or overuse. Recent studies have pointed out the close correlation between LHBT lesions and rotator cuff (RCT tears. Clinicians need to take into account the importance of the LHBT in the presence of other shoulder pathologies. This paper provides an up-to-date overview of recent publications on anatomy, pathophysiology, diagnosis, classification, and current treatment strategies.

  12. The natural history of partial rotator cuff tear evaluated by MRI. Can we predict the prognosis of partial rotator cuff tear by MRI?

    International Nuclear Information System (INIS)

    The cause and progress of the tear in the title are not fully understood and its treatment varies dependently on the injured site, depth, accompanied disease and symptom, and imaging profile. The author classified the tears in 4 types in MRI findings, followed their temporal progression and clinical symptom, and found that this classification in MRI finding was helpful to predict the prognosis, which is described in this paper. Subjects are 47 shoulders of 45 patients (M19/F26, av. age 71.0 y) who underwent conservative treatment of the disease during the time May, 2003-Oct. 2008, periodical MRI (2.7 times in av.) for 18.5 mo in av. and follow-up diagnosis until 24.9 mo in av. MRI is conducted with the machine 1.0 T Siemens harmonicdome to acquire the fast spin echo T1, T2 weighted images, and short inversion time inversion recovery (STIR) coronal, axial and sagittal ones. Tears in MRI are classified in Type 1 (abnormal signal type) (25 shoulders), Type 2 (abnormal signal and swelling type) (7 shoulders), Type 3 (cut off end type) (10 shoulders) and Type 4 (tapered end type) (5 shoulders). The partial rotator cuff tear is suggested to be originated from the denaturation of the cuff with a subsequent certain injury or loading to become Type 1 to 2 and to progress to Type 3 to 4 by continuous acrominal impingement. It is suggested that at the first diagnosis the Type 1 does not have so much serious symptom, but which tends to last long while the symptom is serious in Type 2 and 3: the prognosis in Type 4 is good.

    Objective. To determine the prevalence and extent of residual defects or retears and bursitis-like subacromial abnormalities on MR images after rotator cuff repair in asymptomatic subjects, and to define the clinical relevance of these findings.Design and patients. Fourteen completely asymptomatic patients and 32 patients with residual symptoms were investigated 27-53 months (mean 39 months) after open transosseous reinsertion of the rotator cuff. Coronal T2-weighted turbo spin-echo and turbo STIR or T2-weighted fat-suppressed MR images were obtained. The prevalence and extent of residual defects or retears of the rotator cuff and bursitis-like subacromial abnormalities were determined.Results. Residual defects or retears were detected in three (21%) and bursitis-like abnormalities in 14 (100%) of the 14 asymptomatic patients. Fifteen (47%) residual defects or retears and 31 (97%) bursitis-like abnormalities were diagnosed in the 32 patients with residual symptoms. The size of the residual defects/retears was significantly smaller in the asymptomatic group (mean 8 mm, range 6-11 mm) than in the symptomatic group (mean 32 mm, range 7-50 mm) (t-test, P=0.001). The extent of the bursitis-like subacromial abnormalities did not significantly differ (t-test, P>0.05) between asymptomatic (mean 28 x 3 mm) and symptomatic patients (mean 32 x 3 mm).Conclusion. Small residual defects or retears (<1 cm) of the rotator cuff are not necessarily associated with clinical symptoms. Subacromial bursitis-like MR abnormalities are almost always seen after rotator cuff repair even in patients without residual complaints. They may persist for several years after rotator cuff repair and appear to be clinically irrelevant. (orig.)

    Computed tomography of the soft tissue of the shoulder in cases of calcifying tendinitis of the rotator cuff provides the following information: 1. Localisation of the calcium deposits within the rotator cuff. 2. Contours and density of the calcium deposits correlated with the clinical findings as described by Uhthoff et al. Ill-defined contours and non-homogeneous deposits are associated with more severe clinical features. 3. Computed tomography shows that apatite particles, which are not visible radiologically, may penetrate into the shoulder joint and produce synovitis with an effusion. This is of importance in local therapy.

  17. Rotator cuff metastases: A report of two cases with literature review

    Full Text Available Context: Distant metastases of primary malignancies to the skeletal muscle tissue are a very rare event. Distant metastases that affect the rotator cuff are even rarer, and only a few of cases have been reported so far. Case Report: The present article reports two cases that presented to our hospital with the complaint of shoulder pain and had a soft tissue mass affecting the muscles of the rotator cuff and invading the neighboring bone compartments. One of the patients developed mucoepidermoid cancer metastasis of the submandibular gland, and the other was found to have a malignant epithelial tumor metastasized from the lower lobe of the right lung, whose primary origin could not be diagnosed until the imaging examinations were employed. Ultrasound and magnetic resonance imaging findings are presented in this paper. Conclusion: Metastases to the muscle tissues could be misdiagnosed as primary sarcomas. Because the therapy regiments and prognoses are fairly different for these two entities, the possibility of a metastasis to the muscle tissue must be considered as a differential diagnosis for case of painful soft tissue mass. Ultrasound is very useful in detection of the lesion and acts as a very important tool during guidance for biopsy. Magnetic resonance imaging, however, is a very valuable asset in the evaluation of the borders of the soft tissue mass and its invasive effect on the bony tissues. Particularly when the features such as lobulated contours, peripheral edema, and intratumoral necrosis exist, the possibility of metastases must be considered.

    Objectives: Patient reported outcomes (PRO) are important clinical and research tools that are utilized by orthopedic surgeons in order to assess health outcomes following treatment. This is particularly so in the setting of rotator cuff pathology, in which several different validated patient reported outcomes exist. However, multiple recent studies have demonstrated a lack of standardization in the utilization of these scores. Moreover, many of these scores contain numerous components, thereby making them difficult to administer in a busy ambulatory setting. The goal of this study was to quantitatively assess the commonly used PRO for rotator cuff disease in order to identify the most efficient and comprehensive ones available for clinicians. Methods: Fifteen different PROs commonly used for rotator cuff pathology were selected for review. These outcome tools were assessed by the study team and reviewed for comprehensiveness with regards to assessment of pain, strength, activity, motion, and quality of life. The comprehensiveness and efficiency of each tool was evaluated by inclusion of questions addressing each domain. PROs were also evaluated with a focus of pain criteria (night pain, baseline/general pain, pain during activities of daily living, pain during sport, and pain during work). Finally, all PROs were assessed with regards to comprehensiveness in assessing activity scores (motion/stiffness, activities of daily living, sport, and work). Comprehensiveness scores were calculated by dividing the number of domains or subdomains present by the total domains or subdomains possible. Efficiency was calculated by dividing the number of domains present by the number of questions contained in each PRO. Results: The UCLA, Western Ontario Rotator Cuff Index (WORC), Disabilities of the Arm, Shoulder, and Hand (DASH), PENN, Shoulder Rating Questionnaire (SRQ), and Korean Shoulder Score (KSS) had an overall comprehensiveness score of 1.00 indicating all domains were

    Background: Rotator cuff tearing has been found to be clinically associated with other tendinopathies and compression neuropathies; a significant excess of these phenotypes has been seen in patients with rotator cuff tears. It is unclear if the association is secondary to environmental or genetic influences. Purpose: To examine population-based data for comorbid association of rotator cuff tearing and tendinopathies and compression neuropathies and to determine whether the association extends to relatives of patients with rotator cuff tears, which could suggest a genetic contribution. Study Design: Cross-sectional study; Level of evidence, 3. Methods: The Utah Population Database (UPDB) contains health and genealogical data on over 2 million Utah residents. Current Procedural Terminology, Fourth Revision, codes (CPT 4) and International Classification of Diseases, Ninth Revision, codes (ICD-9) entered in patient records were used to identify patients with rotator cuff tearing and with comorbid tendinopathies and compression neuropathies. We tested the hypothesis of excess familial clustering of these other phenotypes with rotator cuff tearing using a well-established method (estimation of relative risks) in the overall study group of rotator cuff patients (N = 1889). Results: Significantly elevated risk for elbow, hand/wrist, foot/ankle, knee, and hip tendinopathies, as well as for all tendinopathies and compression neuropathies, was observed in rotator cuff tear cases themselves (P tendinopathies (P = 3.1e–3) was also observed in second-degree relatives, and a significant excess of compression neuropathies (P = .03) was observed in third-degree relatives. Conclusion: The current study shows strong evidence of familial clustering of rotator cuff tearing with other tendinopathies and with compression neuropathy. Observed increased risks in spouses and first-degree relatives supports shared environmental risk factors for rotator cuff tearing, most tendinopathies

    Purpose: To evaluate rotator cuff muscles and the glenohumeral (GH) joint in brachial plexus birth injury (BPBI) using MRI and to determine whether any correlation exists between muscular abnormality and the development of glenoid dysplasia and GH joint incongruity. Thirty-nine consecutive BPBI patients with internal rotation contracture or absent active external rotation of the shoulder joint were examined clinically and imaged with MRI. In the physical examination, passive external rotation was measured to evaluate internal rotation contracture. Both shoulders were imaged and the glenoscapular angle, percentage of humeral head anterior to the middle of the glenoid fossa (PHHA) and the greatest thickness of the subscapular, infraspinous and supraspinous muscles were measured. The muscle ratio between the affected side and the normal side was calculated to exclude age variation in the assessment of muscle atrophy. All muscles of the rotator cuff were atrophic, with the subscapular and infraspinous muscles being most severely affected. A correlation was found between the percentage of humeral head anterior to the middle of the glenoid fossa (PHHA) and the extent of subscapular muscle atrophy (r{sub s}=0.45, P=0.01), as well as between its ratio (r{sub s}=0.5, P P=0.01). Severity of rotator cuff muscle atrophy correlated with increased glenoid retroversion and the degree of internal rotation contracture. Glenoid retroversion and subluxation of the humeral head are common in patients with BPBI. All rotator cuff muscles are atrophic, especially the subscapular muscle. Muscle atrophy due to neurogenic damage apparently results in an imbalance of the shoulder muscles and progressive retroversion and subluxation of the GH joint, which in turn lead to internal rotation contracture and deformation of the joint.

  3. Detection of rotator cuff tears: the value of MRI following ultrasound

    International Nuclear Information System (INIS)

    To evaluate the need for additional magnetic resonance imaging (MRI) following ultrasound (US) in patients with shoulder pain and/or disability and to compare the accuracy of both techniques for the detection of partial-thickness and full-thickness rotator cuff tears (RCT). In 4 years, 5,216 patients underwent US by experienced musculoskeletal radiologists. Retrospectively, patient records were evaluated if MRI and surgery were performed within 5 months of US. US and MRI findings were classified into intact cuff, partial-thickness and full-thickness RCT, and were correlated with surgical findings. Additional MR imaging was performed in 275 (5.2%) patients. Sixty-eight patients underwent surgery within 5 months. US and MRI correctly depicted 21 (95%) and 22 (100%) of the 22 full-thickness tears, and 8 (89%) and 6 (67%) of the 9 partial-thickness tears, respectively. The differences in performance of US and MRI were not statistically significant (p = 0.15). MRI following routine shoulder US was requested in only 5.2% of the patients. The additional value of MRI was in detecting intra-articular lesions. In patients who underwent surgery, US and MRI yielded comparably high sensitivity for detecting full-thickness RCT. US performed better in detecting partial-thickness tears, although the difference was not significant. (orig.)

  4. Magnetic Resonance Imaging of the Rotator Cuff in Destroyed Rheumatoid Shoulder: Comparison with Findings during Shoulder Replacement

    International Nuclear Information System (INIS)

    Purpose: To evaluate the predictive value of preoperative magnetic resonance imaging (MRI) with respect to rotator cuff ruptures. Material and Methods: Thirty-one patients with rheumatic disease underwent preoperative MRI before shoulder arthroplasty. The scans were reviewed independently by two experienced radiologists. Three surgeons performed all the replacements (hemiarthroplasties), and the condition of the rotator cuff was assessed. Complete and massive tears of the rotator cuff were recorded and compared at surgery and on MRI. Results: With MRI, 21 shoulders (68%) were classified as having complete or massive tears of the rotator cuff and at surgery 14 shoulders (45%). Cohen's kappa coefficient was 0.44 (95% CI: 0.16 to 0.72) and accuracy 0.71 (95% CI: 0.52 to 0.86). Conclusion: In severely destroyed rheumatoid shoulder, the findings of soft tissues were incoherent both with MRI and at surgery. The integrity of tendons could not readily be elucidated with MRI because of an inflammatory process and scarred tissues; in surgery, too, changes were frequently difficult to categorize. Preoperative MRI of severely destroyed rheumatoid shoulder before arthroplasty turned out to be of only minor importance

    Objectives: Rotator cuff tears (RCTs) are a common cause of shoulder pain and often necessitate surgical repair. Muscle changes including atrophy, fibrosis, and fatty degeneration can develop after RCTs, which may compromise surgical repair and clinical outcomes. Lipoaspirate-derived human perivascular stem cells (PSCs) have demonstrated myogenic and angiogenic potential in other small animal models of muscle injury. We hypothesized that the administration of PSCs following massive RCTs may help to diminish these muscle changes in a small animal model. Methods: A total of 90 immunodeficient mice were used (15 groups, N=6). Each was assigned to one of three surgical groups: i) sham, ii) supraspinatus and infraspinatus tendon transection (TT), or iii) TT and suprascapular nerve denervation (TT+DN). PSCs were harvested from human lipoaspirate and sorted using fluorescence-activated cell sorting into small blood vessel residing pericytes (CD146+ CD34- CD45- CD31-) and large blood perivascular adventitial cells (CD146- CD34+ CD45- CD31-). Mice received either a) no injection, b) saline injection, c) pericyte injection, or d) adventitial cell injection at the time of the index procedure or at two weeks following index surgery. The supraspinatus muscles were harvested six weeks after the index procedure. Muscle atrophy was assessed by measuring percent wet muscle weight change for each sample. Muscle fiber cross-sectional area (CSA), fibrosis, and fatty degeneration were analyzed using Image J™. Additionally, pericytes and adventitial cells were transduced with a luciferase-containing construct. Animals were given injections of luciferin and imaged using IVIS to track in vivo bioluminescence following injections to assess cell viability. Results: Treatment with PSC injection after TT resulted in less wet weight loss and greater muscle fiber CSA than control groups (PBioluminescence imaging demonstrated viability of the injected cells at three weeks following injections

    Full Text Available Abstract Objective After reverse shoulder arthroplasty (RSA external and internal rotation will often remain restricted. A postoperative alteration of the biomechanics in the remaining cuff is discussed as a contributing factor to these functional deficits. Methods In this study, muscle moment arms as well as origin-to-insertion distance (OID were calculated using three-dimensional models of the shoulder derived from CT scans of seven cadaveric specimens. Results Moment arms for humeral rotation are significantly smaller for the cranial segments of SSC and all segments of TMIN in abduction angles of 30 degrees and above (p ≤ 0.05. Abduction moment arms were significantly decreased for all segments (p ≤ 0.002. OID was significantly smaller for all muscles at the 15 degree position (p ≤ 0.005, apart from the cranial SSC segment. Conclusions Reduced rotational moment arms in conjunction with the decrease of OID may be a possible explanation for the clinically observed impaired external and internal rotation.

    Arthroscopic decompression and cuff debridement was performed on 47 cases in 45 consecutive patients with either stage II or stage III impingement syndrome: 19 with no actual tear of the cuff (stage II); 13 with a partial thickness tear (stage IIIa); 10 with complete tear less than 3 cm long (stage IIIb); and 5 with complete tear longer than 3 cm (stage IIIc). Patients were classified into impingement syndrome without tear (Group I), impingement syndrome with partial thickness tear (Group II), and impingement syndrome with full thickness tear (Group III). Group I had 19 cases, group II had 13 cases, and group III had 15 cases. Patients were followed up for an average of 39.3 months (24 approximately 62 months). In group I, postoperative UCLA ratings improved in 18 cases (95%) to satisfactory result rate. In group II, 11 patients (85%) had improvement to satisfactory result rate. In group III, 12 cases (80%) had improvement to satisfactory result rate. The arthroscopic subacromial decompression and rotator cuff debridement was effective in the treatment of subacromial impingement syndrome. PMID:9170017

    Full Text Available From the first shoulder arthroscopy performed on a cadaver in 1931, shoulder arthroscopy has grown tremendously in its ability to diagnose and treat pathologic conditions about the shoulder. Despite improvements in arthroscopic techniques and instrumentation, it is only recently that arthroscopists have begun to explore precise anatomical structures within the subdeltoid space. By way of a thorough bursectomy of the subdeltoid region, meticulous hemostasis, and the reciprocal use of posterior and lateral viewing portals, one can identify a myriad of pertinent ligamentous, musculotendinous, osseous, and neurovascular structures. For the purposes of this review, the subdeltoid space has been compartmentalized into lateral, medial, anterior, and posterior regions. Being able to identify pertinent structures in the subdeltoid space will provide shoulder arthroscopists with the requisite foundation in core anatomy that will be required for challenging procedures such as arthroscopic subscapularis mobilization and repair, biceps tenodesis, subcoracoid decompression, suprascapular nerve decompression, quadrangular space decompression and repair of massive rotator cuff tears.

  9. The analysis of spatial relationship between the rotator cuff and the subacromial space in different arm positions

    International Nuclear Information System (INIS)

    Objective: To explore the distance between the acromion and the humerus head at different arm abduction to observe whether it changes or not, to determine at which position the distance is smallest, and to evaluate the relationship between the subacromial space and the rotator cuff. Methods: Fifteen normal volunteers were examined with MRI in six arm positions, and the coronal thin images were obtained with a spin echo sequence. Using a special positioning device, the arm was placed at 0 degree, 30 degree, 60 degree, 90 degree, 120 degree and 150 degree arm abduction, respectively. Of them, 0 degree-90 degree positions were not rotated, while 120 degree and 150 degree positions were slight internal rotated. The minimal distance of acromion-humerus (A-H) and clavicle-humerus (C-H), and the spatial relationship between the rotator cuff and the subacromial space were measured and observed. Results: The values of A-H and C-H at 60 degree - 150 degree arm abduction were obviously smaller than those at 0 degree-30 degree arm abduction (P0.05). The rotator cuff (mainly supraspinatus tendon) just went through between the acromion and the humerus at 60 degree - 120 degree arm positions but not at 0 degree, 30 degree and 150 degree arm positions. So at 60 degree - 120 degree arm positions, rotator cuff between the humerus and the acromion was often impinged. Conclusion: The closest contact between the supraspinatus tendon and subacromial space occurs at 60 degree - 120 degree abduction. The findings testify that the patients with impingement syndrome have shoulder pain at 60 degree - 120 degree abduction in clinic from etiology and pathology. In the future, MRI-based analyses should allow investigating the morphological basis of the impingement syndrome, choosing the appropriate therapy, and minimizing failure rates of surgery

    [Purpose] For maximum efficiency and to prevent injury during javelin throwing, it is critical to maintain muscle balance and coordination of the rotator cuff and the glenohumeral joint. In this study, we investigated the change in the rotator cuff muscle strength, throw distance and technique of javelin throwers after they had performed a specific physical training that combined elements of weight training, function movement screen training, and core training. [Subjects] Ten javelin throwers participated in this study: six university athletes in the experimental group and four national-level athletes in the control group. [Methods] The experimental group performed 8 weeks of the specific physical training. To evaluate the effects of the training, measurements were performed before and after the training for the experimental group. Measurements comprised anthropometry, isokinetic muscle strength measurements, the function movement screen test, and movement analysis. [Results] After the specific physical training, the function movement screen score and external and internal rotator muscle strength showed statistically significant increases. Among kinematic factors, only pull distance showed improvement after training. [Conclusion] Eight weeks of specific physical training for dynamic stabilizer muscles enhanced the rotator cuff muscle strength, core stability, throw distance, and flexibility of javelin throwers. These results suggest that specific physical training can be useful for preventing shoulder injuries and improving the performance for javelin throwers. PMID:25364111

    Angela E Kedgley

    2013-01-01

    Full Text Available Purpose: Double-row suture anchor fixation of the rotator cuff was developed to reduce repair failure rates. The purpose of this study was to determine the effects of simulated rotator cuff tears and subsequent repairs using single- and double-row suture anchor fixation on three-dimensional shoulder kinematics. It was hypothesized that both single- and double-row repairs would be effective in restoring active intact kinematics of the shoulder. Materials and Methods: Sixteen fresh-frozen cadaveric shoulder specimens (eight matched pairs were tested using a custom loading apparatus designed to simulate unconstrained motion of the shoulder. In each specimen, the rotator cuff was sectioned to create a medium-sized (2 cm tear. Within each pair, one specimen was randomized to a single-row suture anchor repair, while the contralateral side underwent a double-row suture anchor repair. Joint kinematics were recorded for intact, torn, and repaired scenarios using an electromagnetic tracking device. Results: Active kinematics confirmed that a medium-sized rotator cuff tear affected glenohumeral kinematics when compared to the intact state. Single- and double-row suture anchor repairs restored the kinematics of the intact specimen. Conclusions: This study illustrates the effects of medium-sized rotator cuff tears and their repairs on active glenohumeral kinematics. No significant difference ( P ≥ 0.10 was found between the kinematics of single- and double-row techniques in medium-sized rotator cuff repairs. Clinical Relevance: Determining the relative effects of single- and double-row suture anchor repairs of the rotator cuff will allow physicians to be better equipped to treat patients with rotator cuff disease.

    Full Text Available Abstract Background Shoulder pain is a common health problem. The purpose of this study was to assess the associations of lifestyle factors, metabolic factors and carotid intima-media thickness with shoulder pain and chronic (> 3 months rotator cuff tendinitis. Methods In this cross-sectional study, the target population consisted of subjects aged 30 years or older participating in a national Finnish Health Survey during 2000-2001. Of the 7,977 eligible subjects, 6,237 (78.2% participated in a structured interview and clinical examination. Chronic rotator cuff tendinitis was diagnosed clinically. Weight-related factors, C-reactive protein and carotid intima-media thickness were measured. Results The prevalence of shoulder joint pain during the preceding 30 days was 16% and that of chronic rotator cuff tendinitis 2.8%. Smoking, waist circumference and waist-to-hip ratio were related to an increased prevalence of shoulder pain in both genders. Metabolic syndrome, type 2 diabetes mellitus and carotid intima-media thickness were associated with shoulder pain in men, whereas high level of C-reactive protein was associated with shoulder pain in women. Increased waist circumference and type 1 diabetes mellitus were associated with chronic rotator cuff tendinitis in men. Conclusions Our findings showed associations of abdominal obesity, some other metabolic factors and carotid intima-media thickness with shoulder pain. Disturbed glucose metabolism and atherosclerosis may be underlying mechanisms, although not fully supported by the findings of this study. Prospective studies are needed to further investigate the role of lifestyle and metabolic factors in shoulder disorders.

    An imbalance between matrix metalloproteases (MMPs) and the tissue inhibitors of metalloproteases (TIMPs) may have a negative impact on the healing of rotator cuff tears. The aim of the project was to assess a possible relationship between clinical and radiographic characteristics of patients such as the age, sex, as well as the degenerative status of the tendon and the MMPs and TIMPs in their tenocyte-like cells (TLCs). TLCs were isolated from ruptured supraspinatus tendons and quantitative ...

    Full Text Available Background/Aim. Recurrent instability of the shoulder joint is frequently difficult to differentiate from diseased or injured rotator cuff or tendon of the forearm flexor (m. biceps brachii. Shoulder joint arthroscopy has been only recently introduced into instable shoulder joint lesion examination. The aim of this study was to present and analyze an arthroscopic finding on instable shoulder joint in order to determine causes and mechanisms of instability, as well as principles of surgical treatment. Methods. Arthroscopy of the shoulder joint was performed in 158 patients with at least one documented shoulder joint dislocation. These patients were divided into two groups. The group I included the patients with one to three dislocations, while the group II those with more than three dislocations. Preoperative diagnosis was based on anamnestic data and clinical examination using specific tests, and on the diagnosis of shoulder joint using radiography or computed tomography. Results. Out of the total number of the patients 138 (87.34% had injury of the anterior patellar brim, 119 (75.32% had failure of the anterior capsule, 126 (79.75% had compressive cartilage injury of the posterior part of the head of the upper arm bone (Hill-Sachs lesion, 102 (64.56% had insufficiency of glenohumeral tendon, 11 (6.96 had complete cut of the rotator cuff, 23 (14.56% had injury of the posterior patellar brim, 12 (7.59% had injury of the upper anterior-posterior patellar brim (SLAP. Conclusion. According to the obtained results it could be concluded that there is no a unique injury that leads to shoulder joint instability. It is necessary to point out to the significance of anamnesis and clinical examination in making diagnosis. Arthroscopic diagnostics is indicated in clinically unreliable findings as an additional method for determining operative treatment.

    Full Text Available Objectives. The objective of this study was to compare the damage to the rotator cuff tendons caused by four different anchor systems. Methods. 20 cadaveric human shoulder joints were used for transtendon insertion of four anchor systems. The Healix Peek, Fastin RC, Bio-Corkscrew Suture, and Healix Transtend anchors were inserted through the tendons using standard transtendon procedures. The areas of tendon damage were measured. Results. The areas of tendon damage (mean ± standard deviation, n=7 were 29.1 ± 4.3 mm2 for the Healix Peek anchor, 20.4 ± 2.3 mm2 for the Fastin RC anchor, 23.4 ± 1.2 mm2 for the Bio-Corkscrew Suture anchor, 13.7 ± 3.2 mm2 for the Healix Transtend anchor inserted directly, and 9.1 ± 2.1 mm2 for the Healix Transtend anchor inserted through the Percannula system (P<0.001 or P<0.001, compared to other anchors. Conclusions. In a cadaver transtendon rotator cuff repair model, smaller anchors caused less damage to the tendon tissues. The Healix Transtend implant system caused the least damage to the tendon tissues. Our findings suggest that smaller anchors should be considered when performing transtendon procedures to repair partial rotator cuff tears.

    Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

  3. The value of conventional radiograph, CT, MR arthrography in diagnosis of traumatic rotator-cuff tears of the shoulder

    International Nuclear Information System (INIS)

    Objective: To evaluate the conventional arthrography(CA), CT arthrography(CTA), and MR arthrography (MRA) in diagnosis of traumatic rotator-cuff tears of the shoulder. Methods: Twenty patients with traumatic rotator-cuff tears confirmed by arthroscopy were retrospectively reviewed in this study. Glenohumeral joints were punctured percutaneously under fluoroscopic guidance, and 15-20 ml of mixed contrast were injected [10 ml of iodinated contrast (Omnipaque) mixed with 20 ml of 3 mmol/L gadopentetate dimeglumine solution(3 ml of 0.5 mol/L Magnevist in 500 ml of normal saline)] ,and then CA, CTA and MRA was taken within 45 minutes. Result: 100% (9/9) of diagnostic accuracy was obtained in any of conventional, CT or MR shoulder arthrography in the state of complete tears. However, the accuracy of CA,CTA or MRA was 27.3% (3/11), 18.2% (2/11), 66.7% (7/11)respectively in the state of partial tears. Conclusion: MRA is more effective to demonstrate the rotator cuff tears compared to CA or CTA

  5. Arthrography, ultrasound and MR imaging in the evaluation of the rotator cuff: a prospective study

    International Nuclear Information System (INIS)

    Purpose: To evaluate the accuracy of arthrography, ultrasound and MR imaging in rotator cuff disease. Methods: 40 patients suffering from subacromial impingement syndrome for at least three months and who were selected for surgery, underwent ultrasound, bouble-contrast arthrography and MR imaging. Patient preselection focused on partial and small complete tears. Results: 13/26 surgically confirmed tears were partial tears (articular surface: 10, bursal surface: 2, intrasubstance tearing: 1). Arthrography, ultrasound and MR imaging yield a sensitivity for complete tears of 91%, 69% and 92% with a specificity of 100%, 93% and 93%. For partial tears sensitivity was 50%, 69% and 69% with a specificity of 100%, 79% and 86%. Concerning evaluation of localisation, extent and correct classification ultrasound was correct in 17/26 cases, MR in 21/26 cases. Conclusion: Arthrography is not helpful in detecting partial tears. Ultrasound and MR imaging yield comparable accuracy. MR imaging has advantages concerning better evaluation of extent, location and classification as well as for the detection of associated pathologies. (orig.)

  6. Fatty degeneration of the rotator cuff muscles on pre- and postoperative CT arthrography (CTA): is the Goutallier grading system reliable?

    International Nuclear Information System (INIS)

    To retrospectively evaluate fatty degeneration (FD) of rotator cuff muscles on CTA using Goutallier's grading system and quantitative measurements with comparison between pre- and postoperative states. IRB approval was obtained for this study. Two radiologists independently reviewed pre- and postoperative CTAs of 43 patients (24 males and 19 females, mean age, 58.1 years) with 46 shoulders confirmed as full-thickness tears with random distribution. FD of supraspinatus, infraspinatus/teres minor, and subscapularis was assessed using Goutallier's system and by quantitative measurements of Hounsfield units (HUs) on sagittal images. Changes in FD grades and HUs were compared between pre- and postoperative CTAs and analyzed with respect to preoperative tear size and postoperative cuff integrity. The correlations between qualitative grades and quantitative measurements and their inter-observer reliabilities were also assessed. There was statistically significant correlation between FD grades and HU measurements of all muscles on pre- and postoperative CTA (p 0.05). The average dose-length product (DLP, mGy . cm) was 365.2 mGy . cm (range, 323.8-417.2 mGy . cm) and estimated average effective dose was 5.1 mSv. Goutallier grades correlated well with HUs of rotator cuff muscles. Reliability was excellent for both systems, except for FD grade of IST/TM muscles, which may be more reliably assessed using quantitative measurements. (orig.)

    Calcifying tendinopathy (CT) of the shoulder is a common painful disorder, although the etiology and pathogenesis remain largely unknown. Recent theories about the role of excessive mechanical load in the genesis of CT have been proposed. Driven by the interest for these new theories, we investigated the hypothesis of a relationship between work-related repetitive movements of the upper arm, considered a potential cause of shoulder overload, and the presence of shoulder CT. A secondary aim was to obtain data on CT prevalence in a female sample from the working-age general population, as little data currently exist. 199 supermarket cashiers and 304 female volunteers recruited from the general population underwent a high-resolution ultrasonography of the rotator cuffs of both shoulders, and the presence of tendinopathies, with or without calcification, was recorded. The prevalence of calcific tendinopathy was 22.6 % in the cashiers group and 24.4 % in the control group. There were no statistically significant differences in the prevalence of calcifications between the two groups (p = 0.585), either for the dominant shoulder [OR = 0.841 (95 % CI 0.534-1.326)] or for the non-dominant shoulder [OR = 0.988 (95 % CI 0.582-1.326)]. We observed bilateral calcifications in 8.5 % of cashiers, and 9.6 % of controls, and an increase in prevalence of CT with age in both groups. Work-related repetitive movements of the upper arm did not induce a higher prevalence of shoulder CT compared with the female sample from the general population. If CT etiopathogenesis is related to mechanical load, CT onset may be influenced not only by loading history, but also by individual factors. Level of evidence Prognosis study, Level II.

    Full Text Available Purpose: The goal of this study was to compare the cheese-wiring effects of three sutures with different coefficients of friction. Materials and methods: Sixteen human cadaveric shoulders were dissected to expose the distal supraspinatus and infraspinatus muscle tendons. Three sutures were stitched through the tendons: #2 Orthocord™ suture (reference #223114, DePuy Mitek, Inc., Raynham, MA, #2 ETHIBONDFNx01 EXCEL Suture, and #2 FiberWire® suture (FiberWire® , Arthrex, Naples, FL. The sutures were pulled by cyclic axial forces from 10 to 70 N at 1 Hz for 1000 cycles through a MTS machine. The cut-through distance on the tendon was measured with a digital caliper. Results: The cut-through distance in the supraspinatus tendons (mean ± standard deviation, n = 12 were 2.9 ± 0.6 mm for #2 Orthocord™ suture, 3.2 ± 1.2 mm for #2 ETHIBONDFNx01 suture, and 4.2 ± 1.7 mm for #2 FiberWire® suture. The differences were statistically significant analyzing with analysis of variance (P = 0.047 and two-tailed Student′s t-test, which showed significance between Orthocord™ and FiberWire® sutures (P = 0.026, but not significant between Orthocord™ and ETHIBONDFNx01 sutures (P = 0.607 or between ETHIBONDFNx01 and FiberWire® sutures (P = 0.103. Conclusion: The cheese-wiring effect is less in the Orthocord™ suture than in the FiberWire® suture in human cadaveric supraspinatus tendons. Clinical Relevance: Identification of sutures that cause high levels of tendon cheese-wiring after rotator cuff repair can lead to better suture selection.

    This study was designed to investigate the location of cystic lesions in the greater tuberosity of the humerus and the relationship to rotator cuff tears and age. A total of 78 patients (age range, 19-82 years; mean age, 51 years) who underwent arthroscopy or open surgery after MR arthrography (MRA) for a painful shoulder were enrolled in the study. The location of the cystic lesions were classified as 'A' for a supraspinatus insertion site, as 'C' for an infraspinatus insertion site, as 'B' for both a supraspinatus and infraspinatus insertion site, as 'BG' for a site posterior to the bicipital groove and as 'P' for a site at the bare area of the humeral head. The location of cystic lesions and supraspinatus and infraspinatus tears were evaluated on MRA. Statistical analyses used the chi-squared test and logistic regression. 'BG' and 'A' cystic lesions were related to the presence of a supraspinatus tear, 'C' cystic lesions were related to the presence of an infraspinatus tear and 'B' cystic lesions were related to the presence of both supraspinatus and infraspinatus tears (p < 0.05). 'P' cystic lesions were not related to the presence of rotator cuff tears. The incidence of cystic lesions increased with age, but with no statistical correlation. Cystic lesions at the supraspinatus and infraspinatus insertion sites are useful to predict the presence of a rotator cuff tear, but cystic lesions were not age related

    The purpose of this study was to evaluate the necessity of intra-articular gadolinium versus saline alone in magnetic resonance arthrography (MRA) of the shoulder. Our database was reviewed for 100 consecutive shoulder MRA examinations performed between January 2007 and December 2007. Patient information was blinded and images were retrospectively reviewed by at least two radiologists with dedicated musculoskeletal training. T2-weighted (T2W) images were initially analyzed in isolation to simulate MRA with saline alone. After a delay, the full study was analyzed including T1-weighted (T1W) and T2W images. If there was a significant discordance between the two analyses with regard to rotator cuff or labral pathology, the study was again reviewed by all evaluators in consensus to determine if the T1W images offered additional diagnostic information and increased diagnostic confidence. Of the 100 MRA examinations, there were 15 discordant cases. Two cases were discordant with regard to rotator cuff pathology and 13 were discordant on the basis of labral pathology. When the discordant cases were reviewed in consensus, the T2W images appeared to display rotator cuff and labral pathology as definitively as the T1W images. Interobserver and intraobserver variability was favored to have played a role in causing the discordances. MRA of the shoulder performed with joint distention provided by saline alone appears to offer equivalent diagnostic information to MRA performed with gadolinium enhancement. This protocol modification improves efficiency by eliminating several image series and provides a small cost savings by eliminating gadolinium. (orig.)

    Ultrasound-guided percutaneous barbotage is an effective treatment for rotator cuff calcific tendinopathy, providing rapid and substantial pain relief. We present the case of a 49-year-old woman with aggravated pain early after ultrasound-guided barbotage of a large calcific deposit in the supraspinatus tendon. Subsequent examination revealed a thick calcification spreading along the subacromial-subdeltoid bursa space, suggesting acute calcific bursitis complicated by barbotage. Additional barbotage alleviated her pain completely. Therefore, a high index of suspicion for acute calcific bursitis is required in patients with unresolved or aggravated pain after barbotage. Repeated barbotage could be effective for this condition. PMID:26902864

    Objective To study the MR characterizations of supraspinatus and infraspinatus tendon lesions by comparing with gross anatomy and histopathology. Methods The study group consisted of 20 cadaver shoulders which were underwent the same imaging protocols of conventional MRI and MR arthrography. Results SE-T2WI images or MR arthrography respectively possessed of high specificity (95.6%, 100%), but low sensitivity (70.6%, 58.8%) for diagnosing rotator cuff tears. By uniting two images techniques, could remedy its limitations and would markedly increase the sensitivity (88.2%). There were many factors influencing the visualizations of partial thickness tears of rotator cuff on MR images, from which uppermost factors are tear extent, ruptured synovial capsule, scar and synovial proliferation. Conclusion MRI diagnoses of rotator cuff lesions (especially partial thickness tears) must carefully be estimated by combining T2WI images and MR arthrography.

    The current study aimed to measure perioperative changes in driving performance following arthroscopic shoulder surgery using a validated driving simulator.21 patients who underwent arthroscopic surgery for rotator cuff or labral pathology were tested on a driving simulator preoperatively, and 6 and 12 weeks postoperatively. An additional 21 subjects were tested to establish driving data in a control cohort. The number of collisions, centerline crossings, and off-road excursions were recorded for each trial. VAS and SPADI scores were obtained at each visit.The mean number of collisions in the study group significantly increased from 2.05 preoperatively to 3.75 at 6 weeks (pperformance is impaired for at least 6 weeks postoperatively, with a return to normal driving by 12 weeks. Driving is more profoundly affected in conditions that require avoiding a collision and when the dominant driving arm is involved. PMID:27487432

    The different classifications use for the rotator cuff pathology seem to be incomplete. We propose a new classification with many advantages: (1) Differentiate the tendinopathy between less serious (grade 2A) and serious (grade 2B). (2) Recognize the intra-tendinous cleavage of the infra-spinatus associated with complete tear of the supra-spinatus. (3) Differentiate partial and complete tears of the supra-spinatus. We established this classification after a retrospective study of 42 patients operated on for a rotator cuff pathology. Every case had had a preoperative MRI. This classification is simple, especially for the associated intra tendinous cleavage. (authors). 24 refs., 9 figs., 2 tabs.

  19. Development of an Arthroscopic Joint Capsule Injury Model in the Canine Shoulder.

    Directory of Open Access Journals (Sweden)

    David Kovacevic

    Full Text Available The natural history of rotator cuff tears can be unfavorable as patients develop fatty infiltration and muscle atrophy that is often associated with a loss of muscle strength and shoulder function. To facilitate study of possible biologic mechanisms involved in early degenerative changes to rotator cuff muscle and tendon tissues, the objective of this study was to develop a joint capsule injury model in the canine shoulder using arthroscopy.Arthroscopic surgical methods for performing a posterior joint capsulectomy in the canine shoulder were first defined in cadavers. Subsequently, one canine subject underwent bilateral shoulder joint capsulectomy using arthroscopy, arthroscopic surveillance at 2, 4 and 8 weeks, and gross and histologic examination of the joint at 10 weeks.The canine subject was weight-bearing within eight hours after index and follow-up surgeries and had no significant soft tissue swelling of the shoulder girdle or gross lameness. Chronic synovitis and macroscopic and microscopic evidence of pathologic changes to the rotator cuff bony insertions, tendons, myotendinous junctions and muscles were observed.This study demonstrates feasibility and proof-of-concept for a joint capsule injury model in the canine shoulder. Future work is needed to define the observed pathologic changes and their role in the progression of rotator cuff disease. Ultimately, better understanding of the biologic mechanisms of early progression of rotator cuff disease may lead to clinical interventions to halt or slow this process and avoid the more advanced and often irreversible conditions of large tendon tears with muscle fatty atrophy.

    The purpose of this study was to (1) develop and present a technique to quantitatively assess three-dimensional distribution and clustering of intramuscular fat and (2) use the technique to compare spatial characteristics of intramuscular fat in rotator cuff muscles of older adults with and without a supraspinatus tear. Moran's Index (I), an existing quantitative measure of clustering, was extended for use with MRI to allow comparisons across individuals with different size muscles. Sixteen older adults (>60 years) with (N = 6) and without (N = 10) a degenerative supraspinatus tear participated. Following 3D Dixon MRIs of the shoulder, which separates fat from water, rotator cuff muscles were segmented and sectioned and fat% and Moran's I were calculated to assess distribution and clustering, respectively. Moran's I ranged was 0.40-0.92 and 0.39-0.76 for the tear and control subjects, respectively. Compared to uninjured controls, tear subjects demonstrated increased fat distribution (p = 0.036) and clustering (p = 0.020) distally in the supraspinatus. Tear subjects had more pronounced distribution (p intramuscular fat, can be applied to assess clustering of fat in other pathologies and tissues. PMID:26514349

  1. A new method for measurement of subcoracoid outlet and its relationship to rotator cuff pathology at MR arthrography

    International Nuclear Information System (INIS)

    Orthopaedic surgical studies have shown that variations in the vertical distance between the tip of the coracoid process and the supra-glenoid tubercle alter the shape of the subcoracoid outlet. Our objective was to measure the vertical distance between the coracoid tip and the supra-glenoid tubercle (CTGT) on MR and to assess whether this showed better correlation with rotator cuff pathology compared with the axial coraco-humeral distance. A retrospective review was performed of 100 consecutive shoulder MR arthrograms. Vertical distance between the coracoid tip and the supraglenoid tubercle was measured in the sagittal oblique plane. Separate assessment was then made of tendon pathology of the subscapularis, supraspinatus and long head of biceps tendons. Axial coraco-humeral distance was then measured. Correlation between tendon abnormalities and the two measurements was then made. Of the 100 cases, 42 had subscapularis tendon lesions, 21 had lesions of the long head of biceps and 53 had supraspinatus tendon lesions. Mean vertical distance from the coracoid tip to supraglenoid tubercle was greater in those with lesions of any of these tendons and was statistically significant for the supraspinatus group (P = 0.005). Reduced axial coraco-humeral distance was also seen in patients with tendinopathy, although with less statistically significant difference (p = 0.059). Our results support orthopaedic studies that have shown that the vertical distance between the coracoid tip and the supraglenoid tubercle increases the incidence and risk of rotator cuff disease by altering the shape of the subcoracoid outlet.

    Objective To study the imaging features of conventional MR] and MR arthrography(MRA) of rotator cuff tear, evaluate the value of these two techniques,and explore the indications of MRA . Methods 79 cases with rotator cuff tear confirmed by arthroscopic or surgery were divided into five types according to the intraopcrativc findings, Image features of conventional MRI and MRA of rotator cuff tear were retrospectively analysed, and the sensitivity and specificity of the two techniques for various rotator cuff tears were comparatcd. Results Type I rotator cuff tear was showed in 18 cases, the two methods all made the right diagnosis (accuracy rate of 100 % ) ; type Ⅱ rotator cuff tear in 18 cases, conventional MRI correctly diagnosed 1 6 cases(accuracy rate of 89 % ) , MRA correctly diagnosed 18 cascs( accuracy rate of 100%); type Ⅲrotator cuff tear in 7 cases, conventional MRI correctly diagnosed 7 cascs(accuracy rate of 100% ), MRA correctly diagnosed 0 case; type Ⅳ rotator cuff tear in 22 cases, conventional MRI correctly diagnosed 1 6 cascs( accuracy rate of 73 % ) , MRA correctly diagnosed 22 cascs(accuracy rate of 100% ); type Ⅴ rotator cuff tear in 14 cases, conventional MRI correctly diagnosed 14 cascs(accuracy rate of 100%), MRA correctly diagnosed 0 case. Conclusion Conventional MRI can make the right diagnosis for most cases of rotator cuff tear, but not accurate enough for the diagnosis of type Ⅱ and typeⅣ rotator cuff tear, there arc some false positive and false negative dianosis:thc MRA has an important value for the diagnosis of type Ⅱ and type Ⅳ rotator cuff tear, but it docs not help the diagnosis of type Ⅲ and type Ⅴ rotator cuff tear; magnetic resonance shoulder check should first select the conventional MRI. If a suspicious rotator cuff tear is not determined on conventional MRI, MRA should be performed to diagnose type Ⅱ and type Ⅳ rotator cuff tear.%目的 研究肩袖撕裂的磁共振平扫(MRI

    To retrospectively evaluate fatty degeneration (FD) of rotator cuff muscles on CTA using Goutallier's grading system and quantitative measurements with comparison between pre- and postoperative states. IRB approval was obtained for this study. Two radiologists independently reviewed pre- and postoperative CTAs of 43 patients (24 males and 19 females, mean age, 58.1 years) with 46 shoulders confirmed as full-thickness tears with random distribution. FD of supraspinatus, infraspinatus/teres minor, and subscapularis was assessed using Goutallier's system and by quantitative measurements of Hounsfield units (HUs) on sagittal images. Changes in FD grades and HUs were compared between pre- and postoperative CTAs and analyzed with respect to preoperative tear size and postoperative cuff integrity. The correlations between qualitative grades and quantitative measurements and their inter-observer reliabilities were also assessed. There was statistically significant correlation between FD grades and HU measurements of all muscles on pre- and postoperative CTA (p < 0.05). Inter-observer reliability of fatty degeneration grades were excellent to substantial on both pre- and postoperative CTA in supraspinatus (0.8685 and 0.8535) and subscapularis muscles (0.7777 and 0.7972), but fair in infraspinatus/teres minor muscles (0.5791 and 0.5740); however, quantitative Hounsfield units measurements showed excellent reliability for all muscles (ICC: 0.7950 and 0.9346 for SST, 0.7922 and 0.8492 for SSC, and 0.9254 and 0.9052 for IST/TM). No muscle showed improvement of fatty degeneration after surgical repair on qualitative and quantitative assessments; there was no difference in changes of fatty degeneration after surgical repair according to preoperative tear size and post-operative cuff integrity (p > 0.05). The average dose-length product (DLP, mGy . cm) was 365.2 mGy . cm (range, 323.8-417.2 mGy . cm) and estimated average effective dose was 5.1 mSv. Goutallier grades

    Shoulder problems account for 2.4% of GP consultations in the United Kingdom and of those 70% are related to the rotator cuff. Many rotator cuff tears are of a degenerate nature but they can occur as a result of trauma in 8% of cases. Evidence suggests that patients with traumatic rotator cuff tears gain a better outcome in terms of pain and function if the tear is repaired early after injury. A specialist shoulder soft tissue injury clinic was set up in a large UK NHS teaching hospital with the primary purpose in the first year to halve the length of time patients with traumatic rotator cuff tears had to wait to consult a specialist and double the number of patients undergoing surgical repair within three months. The secondary purpose was to ensure that the new clinic was utilised to capacity by the end of the first year. The clinic was later expanded to manage patients with acute glenohumeral joint (GHJ) or acromioclavicular joint (ACJ) dislocations and identify those patients requiring surgical stabilisation. The new service involved referral of all patients presenting to the Accident & Emergency department with recent shoulder trauma and either an inability to raise the arm over shoulder height with a normal set of radiographs, or a confirmed GHJ or ACJ dislocation; to a specialist clinic run by an experienced upper limb physiotherapist. Patients were reassessed and referred for further imaging if required. Those patients found to have traumatic rotator cuff tears or structural instability lesions were listed for expedited surgery. The clinic ran alongside a consultant-led fracture clinic giving fast access to surgical decision-making. The service was reviewed after 3, 6, and 12 months and findings compared to a sample of 30 consecutive patients having undergone rotator cuff repair surgery via the previous pathway. 144 patients were referred to the clinic in the first year: 62 with rotator cuff symptoms, 38 with GHJ instability, 13 with ACJ instability, and 33

    Rotator cuff repair via transosseous tunnels can improve footprint contact area and pressure when compared with suture anchor techniques. A double-row technique has been used clinically to improve footprint coverage by a repaired tendon. We hypothesized that a transosseous-equivalent rotator cuff repair via tendon suture bridges would demonstrate improved pressurized contact between the tendon and tuberosity when compared with a double-row technique. In 6 fresh-frozen human shoulders, a transosseous-equivalent rotator cuff repair was performed: a suture limb from each of 2 medial anchors was bridged over the tendon and fixed laterally with an interference screw (4 suture bridges). In 6 of the contralateral specimens, two types of repair were performed randomly in each specimen: (1) a double-row repair and (2) a transosseous-equivalent repair with a single screw (2 suture bridges). For all repairs, pressure-sensitive film was placed at the tendon-footprint interface, and software was used to obtain measurements. The mean pressurized contact area between the tendon and insertion was significantly greater for the 4-suture bridge technique (124.2 +/- 16.3 mm2, 77.6% footprint) compared with both the double-row (63.3 +/- 28.5 mm2, 39.6% footprint) and 2-suture bridge (99.7 +/- 22.0 mm2, 62.3% footprint) techniques (P bridge technique (0.27 +/- 0.04 MPa) than for the double-row technique (0.19 +/- 0.01 MPa) (P = .002). The transosseous-equivalent rotator cuff repair technique can improve pressurized contact area and mean pressure between the tendon and footprint when compared with a double-row technique. A transosseous-equivalent technique, using suture bridges, may help optimize the healing biology at a repaired rotator cuff insertion. PMID:17321161

    Full Text Available To provide in-vivo evidence for the common biomechanical concept of transverse and craniocaudal force couples in the shoulder that are yielded by both the rotator cuff muscles (RCM and the deltoid and to quantitatively evaluate and correlate the cross-sectional areas (CSA of the corresponding RCM as a surrogate marker for muscle strength using MRI.Fifty patients (mean age, 36 years; age range, 18-57 years; 41 male, 9 female without rotator cuff tears were included in this retrospective study. Data were assessed by two readers. The CSA (mm2 of all rotator cuff muscles was measured on parasagittal T1-weighted FSE sequence at two different positions (at the established "y-position" and at a more medial slice in the presumably maximal CSA for each muscle, i.e., the "set position". The CSA of the deltoid was measured on axial intermediate-weighted FSE sequences at three positions. CSA measurements were obtained using 1.5 Tesla MR-arthrographic shoulder. Pearson's correlation for the corresponding CSA of the force couple as well as was the intraclass correlation coefficient for the inter- and intra-reader agreement was calculated.The mean CSA was 770 mm2 (±167 and 841 mm2 (±191 for the supraspinatus (in the y- and set-positions, respectively and 984 mm2 (±241 and 1568 mm2 (±338 for the infraspinatus. The mean CSA was 446 mm2 (±129 and 438 mm2 (±128 for the teres minor (in the y- and set-positions, respectively and 1953 mm2 (±553 and 2343 mm2 (±587 for the subscapularis. The three measurements of the deltoid revealed a CSA of 3063 mm2 (±839 for the upper edge, 3829 mm2 (±836 for the lower edge and 4069 mm2 (±937 for the middle of the glenoid. At the set position Pearson's correlation of the transverse force couple (subscapularis/infraspinatus showed a moderate positive correlation of r = 0.583 (p<0.0001 and a strong correlation when the CSA of the teres minor was added to the infraspinatus CSA (r = 0.665, p = 0.0008 and a strong positive

    Full Text Available In this article, we describe the basic knowledge about shoulder biomechanics, which is thought to be useful for surgeons. Some clinical reports have described that the excellent outcome after cuff repair without acromioplasty and a limited acromioplasty might be enough for subacromial decompression. It was biomechanically demonstrated that a 10-mm medial shift of the tendon repair site has a minimum effect on biomechanics. Many biomechanical studies reported that the transosseous equivalent repair was superior to other techniques, although the tendon may lose its inherent elasticity. We herein introduce our recent experiment data and latest information on biomechanics.

    Fluid in the subacromial bursa (SAB) is a common finding on magnetic resonance (MR) images of the shoulder, and the implications of this finding have not been clarified. We retrospectively reviewed and correlated the MR features with arthroscopic findings in 21 symptomatic patients who had fluid in the SAB on MR imaging without demonstrable rotator cuff tear. Rotator cuff impingement was the most frequent surgical finding (42.9%). Other frequent surgical observations were glenbid labrum abnormality (28.6%), bursitis (19%), and supraspinatus tendinitis (14.3%). Distribution of acromial types was similar to that reported by Bigliani et al., and impingement was evenly distributed among acromial types in our study population. We conclude that in our patient population group the MR finding of isolated SAB fluid in symptomatic patients is highly likely to be associated with the finding of other abnormalities in the shoulder joint at surgery.

    A preclinical analysis of novel implants used in shoulder surgery requires biomechanical testing conditions close to physiology. Existing shoulder experiments may only partially apply multiple cycles to simulate postoperative, repetitive loading tasks. The aim of the present study was therefore the development of an experimental shoulder simulator with rotating scapula able to perform multiple humeral movement cycles by simulating individual muscles attached to the rotator cuff. A free-hanging, metallic humerus pivoted in a polyethylene glenoid is activated by tension forces of linear electroactuators to simulate muscles of the deltoideus (DELT), supraspinatus (SSP), infraspinatus/teres minor and subscapularis. The abductors DELT and SSP apply forces with a ratio of 3:1 up to an abduction angle of 85°. The rotating scapular part driven by a rotative electro actuator provides one-third to the overall arm abduction. Resulting joint forces and moments are measured by a 6-axis load cell. A linear increase in the DELT and SSP motors is shown up to a maximum of 150 and 50 N for the DELT and SSP, respectively. The force vector in the glenoid resulted in 253 N at the maximum abduction. The present investigation shows the contribution of individual muscle forces attached to the moving humerus to perform active abduction in order to reproducibly test shoulder implants. PMID:24170552

  17. Impingement syndrome of the ankle following supination external rotation trauma: MR imaging findings with arthroscopic correlation

    International Nuclear Information System (INIS)

    Our objective was to identify MR imaging findings in patients with syndesmotic soft tissue impingement of the ankle and to investigate the reliability of these imaging characteristics to predict syndesmotic soft tissue impingement syndromes of the ankle. Twenty-one ankles with chronic pain ultimately proven to have anterior soft tissue impingement syndrome were examined by MR imaging during January 1996 to June 2001. The MR imaging protocol included sagittal and coronal short tau inversion recovery (STIR), sagittal T1-weighted spin echo, axial and coronal proton-density, and T2-weighted spin-echo sequences. Nineteen ankles that underwent MR imaging during the same period of time and that had arthroscopically proven diagnosis different than impingement syndrome served as a control group. Fibrovascular scar formations distinct from the syndesmotic ligaments possibly related to syndesmotic soft tissue impingement were recorded. Arthroscopy was performed subsequently in all patients and was considered the gold standard. The statistical analysis revealed an overall frequency of scarred syndesmotic ligaments of 70% in the group with ankle impingement. Fibrovascular scar formations distinct from the syndesmotic ligaments presented with low signal intensity on T1-weighted images and remained low to intermediate in signal intensity on T2-weighted MR imaging. Compared with arthroscopy, MR imaging revealed a sensitivity of 89%, a specificity of 100%, and a diagnostic accuracy of 93% for scarred syndesmotic ligaments. The frequency of scar formation distinct from the syndesmotic ligaments in patients with impingement syndrome of the ankle was not statistically significantly higher than in the control group. In contrast to that, anterior tibial osteophytes and talar osteophytes were statistically significantly higher in the group with anterior impingement than in the control group. Conventional MR imaging was found to be insensitive for the diagnosis of syndesmotic soft tissue

    Full Text Available BACKGROUND: Previous studies have shown a relationship between shoulder posterior capsule tightness and shoulder pain in overhead athletes. However, this relationship has not been studied in tennis players. OBJECTIVES: Assessment of the shoulder range of motion (ROM, strength and posterior capsule tightness of skilled amateur tennis players who had complaints of dominant shoulder pain in comparison with tennis players without pain. METHOD: Forty-nine skilled amateur tennis players were distributed in 2 groups: Control Group (n=22 and Painful Group (n=27. The first group was composed of asymptomatic subjects, and the second was composed of subjects with shoulder pain on the dominant side. These groups were evaluated to determine the dominant and non-dominant shoulder ROM (internal and external rotation, isometric shoulder strength (internal and external rotation and posterior shoulder tightness by blind evaluators. RESULTS: The ANOVA results indicated significant differences between the groups in the dominant shoulder ROM, posterior capsule tightness, external rotation strength and strength ratio (p<0.05. The intragroup analysis (dominant versus non-dominant in the Painful Group displayed a significant difference for ROM, posterior capsule tightness and external rotation strength (p<0.05. CONCLUSIONS: The tennis players with pain in the dominant shoulder presented greater posterior capsule tightness, internal rotation deficit (ROM, external rotation gain (ROM and deficits in external rotation strength than the tennis players without pain.

    Background: Rotator cuff tears are a common cause of shoulder pain and dysfunction. More recently, there has been a renewed interest in understanding the subscapularis tears. There are multiple articles in the literature showing the short term results of isolated subscapularis tendon repair. However, the midterm and long term outcome studies for arthroscopic subscapularis repair are few. This study evaluates the functional outcome after arthroscopic subscapularis repair. Materials and Methods: The records of 35 patients who underwent an arthroscopic subscapularis repair between May 2008 and June 2012 were included in this retrospective study. The records of all patients were reviewed. There were 22 males and 13 female patients with mean age of 58.2 years (range 41-72 years). All patients had a complete history, physical examination, and radiographs of their shoulders. Visual analogue scale (VAS), range of movements, power of cuff muscles, and modified University of California at Los Angeles (UCLA) score were assessed. Results: The mean followup was 2.8 years (range 2-4 year). Functional outcome after arthroscopic subscapularis repair has an excellent outcome as analysed by clinical outcome, VAS score and UCLA score. Results were analyzed and had statistically significant values. The VAS for pain improved significantly (P < 0.001), and the mean modified UCLA score improved significantly (P < 0.001) from 14.24 ± 4.72 preoperatively to 33.15 ± 2.29 at 2 years postoperative. According to the UCLA system, there were 22 excellent, 11 good, and 2 fair results. Around 95% of patients returned to their usual work after surgery. Conclusion: At a median followup of 2 years, 95% of patients had a good to excellent result after an arthroscopic subscapularis tendon repair. We conclude that the midterm results show that arthroscopic subscapularis repair remains a good option for the treatment of patients with subscapularis tendon repair. PMID:27293291

    Background Arthroscopic subacromial decompression (ASAD) is a commonly performed surgical intervention for shoulder pain. The rationale is that removal of a bony acromial spur relieves symptoms by decompressing rotator cuff tendons passing through the subacromial space. However, the efficacy of this procedure is uncertain. The objective of this trial was to compare the efficacy and cost-effectiveness of ASAD in patients with subacromial pain using appropriate control groups, including placebo...

    Continuous interscalene block is an approved modality for postoperative pain control, but it may cause hemidiaphragmatic paresis. In this study we aimed to determine whether continuous supraclavicular block would provide postoperative analgesia comparable to that of continuous interscalene block and reduce the incidence of hemidiaphragmatic paresis. Patients scheduled for open rotator cuff repair were randomly allocated to receive continuous interscalene (n = 38) or supraclavicular block (n = 37). Both participants and assessing clinicians were blinded to the group allocation. The primary endpoint was the mean pain intensity 24 h after the surgery. Postoperative mean (SD) pain scores at 24 h were similar in the supraclavicular and interscalene groups (2.57 (1.71) vs 2.84 (1.75) respectively; p = 0.478). The incidence of complete or partial hemidiaphragmatic paresis was lower in the supraclavicular group at 1 h after admission to the postanaesthetic care unit and 24 h after the surgery [25 (68%) vs 38 (100%); p = 0.001 and 14 (38%) vs 27 (71%) respectively; p = 0.008]. Continuous supraclavicular block provided comparable analgesia compared with interscalene block with a reduced incidence of complete or partial hemidiaphragmatic paresis for 24 h following surgery.

    To evaluate the prevalence, imaging characteristics and anatomical distribution of tears at the rotator cuff (RC) footprint with MR arthrography (MR-A) of the shoulder. MR arthrograms obtained in 305 patients were retrospectively reviewed. Partial articular-sided supraspinatus tendon avulsions (PASTA), concealed interstitial delaminations (CID), reverse PASTA lesions and full-thickness tears (FT) at the humeral tendon insertion were depicted. Anatomical locations were determined and depths of tears were classified. 112/305 patients showed RC tears, including 63 patients with 68 footprint tears. 34 PASTA lesions were detected with 20/34 involving the anterior supraspinatus (SSP) tendon and 17/34 PASTA lesions were grade I lesions. Most CID lesions (14/23) occurred at the posterior SSP and 20/23 were classified as grade I or II. 9 FT and 2 reverse PASTA lesions were found. Statistical analysis revealed no difference in anatomical location (p = 0.903) and no correlation with overhead sports activity (p = 0.300) or history of trauma (p=0.928). There were significantly more PASTA lesions in patients <40 years of age (p = 0.029). Most RC tears detected with MR-A involve the SSP footprint and are articular-sided with predominance in younger patients, but concealed lesions are not as uncommon as previously thought. (orig.)

  5. Do Matrix Metalloproteases and Tissue Inhibitors of Metalloproteases in Tenocytes of the Rotator Cuff Differ with Varying Donor Characteristics?

    Full Text Available An imbalance between matrix metalloproteases (MMPs and the tissue inhibitors of metalloproteases (TIMPs may have a negative impact on the healing of rotator cuff tears. The aim of the project was to assess a possible relationship between clinical and radiographic characteristics of patients such as the age, sex, as well as the degenerative status of the tendon and the MMPs and TIMPs in their tenocyte-like cells (TLCs. TLCs were isolated from ruptured supraspinatus tendons and quantitative Real-Time PCR and ELISA was performed to analyze the expression and secretion of MMPs and TIMPs. In the present study, MMPs, mostly gelatinases and collagenases such as MMP-2, -9 and -13 showed an increased expression and protein secretion in TLCs of donors with higher age or degenerative status of the tendon. Furthermore, the expression and secretion of TIMP-1, -2 and -3 was enhanced with age, muscle fatty infiltration and tear size. The interaction between MMPs and TIMPs is a complex process, since TIMPs are not only inhibitors, but also activators of MMPs. This study shows that MMPs and TIMPs might play an important role in degenerative tendon pathologies.

    Rotator cuff injury, considered as a resource of pain, disability and dyssomnia to serious decline in the quality of life, is a common disorder of the shoulder joint. Basic principles of rotator cuff repair aim at achieving high initial ifxation strength, maintaining mechanical stability and restoring the anatomic healing of the cuff tendon. After the routine surgical procedure for rotator cuff repair, the biology and histology of the normal enthesis are not restored. Tendon-to-bone healing occurs with a ifbrovascular scar tissue interface that is mechanically inferior to the native insertion site, which may lead to high re-rupture rate. For these reasons, new approaches are required to improve structural healing. Tissue engineering strategies have been suggested to improve the biological environment around the bone-tendon interface and to promote regeneration of the native insertion site. Although experimental applications of growth factors and scaffolds on animal models demonstrate promising results, techniques which can be used in human rotator cuff repair are still very limited. Tissue engineering to improve tendon-to-bone healing has bright future and requires more research before its clinical applications. This review will outline therapies of growth factors, scaffolds and stem cells in tendon healing and rotator cuff repair.

    The high frequency of poor outcome and chronic pain after surgical repair of shoulder rotator-cuff injury (RCI) prompted this study to explore the potential to amplify muscle regeneration using nitric oxide (NO)-based treatment. After preoperative magnetic resonance imaging (MRI), biopsies of supraspinatus and ipsilateral deltoid (as a control) were collected during reparative surgery for RCI. Muscle fiber diameter, the pattern of neuromuscular junctions observed with alpha-bungarotoxin staining, and the γ:ε subunit ratio of acetylcholine receptors in Western blots were examined in tandem with experiments to determine the in vitro responsiveness of muscle satellite cells to activation (indicated by uptake of bromodeoxyuridine, BrdU) by the NO-donor drug, isosorbide dinitrate (ISDN). Consistent with MRI findings of supraspinatus atrophy (reduced occupation ratio and tangent sign), fiber diameter was lower in supraspinatus than in deltoid. ISDN induced a significant increase over baseline (up to 1.8-fold), in the proportion of BrdU+ (activated) Pax7+ satellite cells in supraspinatus, but not in deltoid, after 40 h in culture. The novel application of denervation indices revealed a trend for supraspinatus muscle to have a higher γ:ε subunit ratio than deltoid (P = 0.13); this ratio inversely with both occupancy ratio (P < 0.05) and the proportion of clusters at neuromuscular junctions (P = 0.05). Results implicate possible supraspinatus denervation in RCI and suggest NO-donor treatment has potential to promote growth in atrophic supraspinatus muscle after RCI and improve functional outcome.

  10. Diagnostic and therapeutic impact of MRI and arthrography in the investigation of full-thickness rotator cuff tears

    International Nuclear Information System (INIS)

    Investigation of shoulder pain is important before surgical treatment. The presence or absence of a full-thickness rotator cuff tear (FTRCT) may determine the type of surgical treatment. Both MRI and conventional arthrography can be used, but little is known about their relative diagnostic and therapeutic impact. We performed a prospective trial assessing: (a) the influence of MRI and arthrography results on the clinician's diagnostic thinking (diagnostic impact); (b) the influence of the results on the clinician's therapeutic thinking (therapeutic impact); and (c) the diagnostic performance of the two techniques in patients with surgical confirmation. A total of 104 consecutive patients with shoulder problems referred to a specialist orthopaedic shoulder clinic underwent pre-operative investigation with MRI and arthrography. The surgeon's diagnosis, diagnostic confidence and planned treatment were measured before the investigation, and then again after the results of each investigation. Before the presentation of the investigation results, the patients were randomised into two groups. In one group MRI was presented first; in the other group, arthrography. The MRI results led to fewer changes in diagnostic category (14 of 46, 30 %) than arthrography (20 of 54, 37 %), but the difference was not significant (P > 0.5). Magnetic resonance imaging led to slightly more changes in planned management (17 of 47, 36 %) than arthrography (14 of 55, 25 %), but again the difference was not statistically significant (P > 0.3). The results of the second investigation always had less diagnostic and therapeutic impact than the first. The accuracy of MRI for FTRCT in 38 patients with surgical confirmation was 79 %, sensitivity 81 % and specificity 78 %; the accuracy of arthrography was 82 %, sensitivity 50 % and specificity 96 %. The clinical diagnosis and management plan can be adequately defined by a single radiological investigation. Magnetic resonance imaging and arthrography

    Background Tennis is believed to be potentially harmful for the shoulder, therefore the purpose of this study is to evaluate the anatomy of the rotator cuff and the coraco-humeral ligament (CHL) in a-symptomatic non-elite junior tennis players with high-resolution ultrasound (US). Methods From August 2009 to September 2010 n = 90 a-symptomatic non-elite junior tennis players (mean age ± standard deviation: 15 ± 3) and a control group of age- and sex- matched subjects were included. Shoulder assessment with a customized standardized protocol was performed. Body mass index, dominant arm, years of practice, weekly hours of training, racket weight, grip (Eastern, Western and semi-Western), kind of strings were recorded. Results Abnormalities were found at ultrasound in 14/90 (15%) players. Two players had supraspinatus tendinosis, two had subacromial impingement and ten had subacromial bursitis. CHL thickness resulted comparable in the dominant and non-dominant arms (11.3 ± 4.4 mm vs. 13 ± 4.2, p > 0.05). Multivariate analysis demonstrated that no association was present among CHL thickness and the variables evaluated. In the control group, abnormalities were found at ultrasound in 6/60 (10%) subjects (sub-acromial bursitis). No statistically significant differences between players and control group were found (p = 0.71). Conclusion In a-symptomatic non-elite junior tennis players only minor shoulder abnormalities were found. PMID:25034864

    Objectives: To compare the effect of graded physiotherapeutic training of the rotator cuff versus arthroscopic subacromial decompression in patients with subacromial impingement. Methods: Randomised controlled trial with 12 months' follow up in a hospital setting. Ninety consecutive patients aged 18 to 55 years were enrolled. Symptom duration was between six months and three years. All fulfilled a set of diagnostic criteria for rotator cuff disease, including a positive impingement sign. Patients were randomised either to arthroscopic subacromial decompression, or to physiotherapy with exercises aiming at strengthening the stabilisers and decompressors of the shoulder. Outcome was shoulder function as measured by the Constant score and a pain and dysfunction score. "Intention to treat" analysis was used, with comparison of means and control of confounding variables by general equation estimation analysis. Results: Of 90 patients enrolled, 84 completed follow up (41 in the surgery group, 43 in the training group). The mean Constant score at baseline was 34.8 in the training group and 33.7 in the surgery group. After 12 months the mean scores improved to 57.0 and 52.7, respectively, the difference being non-significant. No group differences in mean pain and dysfunction score improvement were found. Conclusions: Surgical treatment of rotator cuff syndrome with subacromial impingement was not superior to physiotherapy with training. Further studies are needed to qualify treatment choice decisions, and it is recommended that samples are stratified according to disability level. PMID:15834056

    Tendon bone healing of the rotator cuff is often associated with non-healing or recurrent defects, which seems to be influenced by the patient’s age and sex. The present study aims to examine cellular biological characteristics of tenocyte-like cells that may contribute to this impaired rotator cuff healing. Moreover, a therapeutic approach using growth factors could possibly stimulate tendon bone healing. Therefore, our second aim was to identify patient groups who would particularly benefit from growth factor stimulation. Tenocyte-like cells isolated from supraspinatus tendons of female donors younger and older than 65 years of age were characterized with respect to different cellular biological parameters, such as cell density, cell count, marker expression, collagen-I protein synthesis, and stem cell potential. Furthermore, cells of the donor groups were stimulated with BMP-2 and BMP-7 (200 and 1000 ng/ml) in 3D-culture and analyzed for cell count, marker expression and collagen-I protein synthesis. Female donors older than 65 years of age showed significantly decreased cell count and collagen-I protein synthesis compared to cells from donors younger than 65 years. Cellular biological parameters including cell count, collagen-I and –III expression, and collagen-I protein synthesis of cells from both donor groups were stimulated with BMP-2 and BMP-7. The cells from donors older than 65 years revealed a decreased stimulation potential for cell count compared to the younger group. Cells from female donors older than 65 years of age showed inferior cellular biological characteristics. This may be one reason for a weaker healing potential observed in older female patients and should be taken into consideration for tendon bone healing of the rotator cuff. PMID:23825642

  6. A comparison of magnetic resonance arthrography and arthroscopic findings in the assessment of anterior shoulder dislocations

    The aim of this study is to establish the sensitivity and specificity of MRA in the investigation of patients with traumatic anterior shoulder dislocations. A retrospective analysis of consecutive patients undergoing both magnetic resonance arthrography and arthroscopic assessment after a traumatic anterior shoulder dislocation between January 2011 and 2014 was performed. Demographic data were collected from electronic records. Images were interpreted by 8 musculoskeletal radiologists and patients were treated by 8 consultant orthopaedic surgeons. Arthroscopic findings were obtained from surgical notes and these findings were used as a reference for MRA. The sensitivity, specificity, and positive predictive value were calculated for the different injuries. Sixty-nine patients underwent both an MRA and shoulder arthroscopy during the study period; however, clinical notes were unavailable in 9 patients. Fifty-three patients (88 %) were male, the mean age was 28 years (range 18 to 50) and 16 subjects (27 %) had suffered a primary dislocation. The overall sensitivity and specificity of MRA to all associated injuries was 0.9 (CI 0.83-0.95) and 0.94 (CI 0.9-0.96) retrospectively. The lowest sensitivity was seen in osseous Bankart 0.8 (CI 0.44-0.96) and superior labral tear (SLAP) lesions 0.5 (CI 0.14-0.86). The overall positive predictive value was 0.88 (CI 0.76-0.91) with the lowest values found in rotator cuff 0.4 (CI 0.07-0.83) and glenohumeral ligament (GHL) lesions 0.29 (CI 0.05-0.7). Magnetic resonance angiography has a high sensitivity when used to identify associated injuries in shoulder dislocation, although in 8 patients (13 %) arthroscopy identified an additional injury. The overall agreement between MRA and arthroscopic findings was good, but the identification of GHL and rotator cuff injuries was poor. (orig.)

  8. Leukocyte- and platelet-rich fibrin (L-PRF) for long-term delivery of growth factor in rotator cuff repair: review, preliminary results and future directions.

    Science.gov (United States)

    Zumstein, Matthias A; Berger, Simon; Schober, Martin; Boileau, Pascal; Nyffeler, Richard W; Horn, Michael; Dahinden, Clemens A

    2012-06-01

    Surgical repair of the rotator cuff repair is one of the most common procedures in orthopedic surgery. Despite it being the focus of much research, the physiological tendon-bone insertion is not recreated following repair and there is an anatomic non-healing rate of up to 94%. During the healing phase, several growth factors are upregulated that induce cellular proliferation and matrix deposition. Subsequently, this provisional matrix is replaced by the definitive matrix. Leukocyte- and platelet-rich fibrin (L-PRF) contain growth factors and has a stable dense fibrin matrix. Therefore, use of LPRF in rotator cuff repair is theoretically attractive. The aim of the present study was to determine 1) the optimal protocol to achieve the highest leukocyte content; 2) whether L-PRF releases growth factors in a sustained manner over 28 days; 3) whether standard/gelatinous or dry/compressed matrix preparation methods result in higher growth factor concentrations. 1) The standard L-PRF centrifugation protocol with 400 x g showed the highest concentration of platelets and leukocytes. 2) The L-PRF clots cultured in medium showed a continuous slow release with an increase in the absolute release of growth factors TGF-β1, VEGF and MPO in the first 7 days, and for IGF1, PDGF-AB and platelet activity (PF4=CXCL4) in the first 8 hours, followed by a decrease to close to zero at 28 days. Significantly higher levels of growth factor were expressed relative to the control values of normal blood at each culture time point. 3) Except for MPO and the TGFβ-1, there was always a tendency towards higher release of growth factors (i.e., CXCL4, IGF-1, PDGF-AB, and VEGF) in the standard/gelatinous- compared to the dry/compressed group. L-PRF in its optimal standard/gelatinous-type matrix can store and deliver locally specific healing growth factors for up to 28 days and may be a useful adjunct in rotator cuff repair. PMID:21740372

    Full Text Available A lesão do manguito rotador é a mais freqüente patologia do ombro. Cerca de 180 pacientes foram tratados conservadoramente nos dois Serviços nos anos de 1996 e 1997. Este grupo recebeu uma ampla gama de tratamentos (apenas medicação, exercícios caseiros, infiltração, fisioterapia, etc.. Este estudo avaliou os resultados do tratamento conservador em 26 pacientes com rupturas parcial e total do manguito rotador. O protocolo consistiu de um programa com 6 meses de duração que incluiu terapia miofascial específica, exercícios ativos assistidos e de fortalecimento dos músculos do manguito rotador e da musculatura axioescapular. Os fatores de inclusão no estudo foram: 1 realizar todo o programa com apenas um reabilitador; 2 não ter recebido infiltração; 3 não ter tido cirurgia prévia; 4 não ter reumatopatia diagnosticada. Seis meses após a alta, dezoito pacientes (69,22% apresentavam resultado satisfatório, enquanto que os demais 08 casos (30,78% foram considerados insatisfatórios e tiveram indicação cirúrgica.The lesion of rotator cuff is the most frequent lesion of the shoulder. Circa 180 patients were conservatively treated in both Clinics during the years of 1976 and 1997. This group of patients received a wide range of treatments (only medication, home exercises, infiltration, physiotherapy, etc. This study evaluated the results of the conservative treatment in 26 patients with partial and total rupture of the rotator cuff. The protocol consisted of a program with duration of 6 months including specific miofascial therapy, assisted active exercises and of strengthening of the muscles of the rotator cuff and axioscapular musculature. The inclusion criteria of the study were: 1 to carry the program with just one reabilitator; 2 no previous infiltration; 3 no previous surgery; 4 absence of diagnosed rheumatopathy.

    Full Text Available To test the hypothesis that a platelet-rich plasma (PRP plus bioactive glass (BG mixture could shorten the tendon-bone healing process in rotator cuff tendon repair, thirty mature male New Zealand white rabbits were randomly divided into three groups, Control, PRP, and PRP + BG. All groups underwent a surgical procedure to establish a rotator cuff tendon healing model. Mechanical examinations and histological assays were taken to verify the adhesion of the tendon-bone. Real-time PCR was adopted to analyze Bone Morphogenetic Protein-2 (BMP-2. The maximum load-to-failure value in mechanical examinations was significantly higher in the PRP + BG group than that in the control group after six weeks (Control 38.73 ± 8.58, PRP 54.49 ± 8.72, PRP + BG 79.15 ± 7.62, p < 0.001, but it was not significantly different at 12 weeks (PRP 74.27 ± 7.74, PRP + BG 82.57 ± 6.63, p = 0.145. In histological assays, H&E (hematoxylin-eosin staining showed that the interface between the tendon-bone integration was much sturdier in the PRP + BG group compared to the other two groups at each time point, and more ordered arranged tendon fibers can be seen at 12 weeks. At six weeks, the mRNA expression levels of BMP-2 in the PRP + BG group were higher than those in the other groups (PRP + BG 0.65 ± 0.11, PRP 2.284 ± 0.07, Control 0.12 ± 0.05, p < 0.05. However, there was no significant difference in the mRNA expression levels of BMP-2 among the three groups at 12 weeks (p = 0.922, 0.067, 0.056. BMP-2 levels in PRP and PRP+BG groups were significantly lower at 12 weeks compared to six weeks (p = 0.006, <0.001.We found that the PRP + BG mixture could enhance tendon-bone healing in rotator cuff tendon repair.

    Background For partial-thickness tears of the rotator cuff, double-row fixation and transtendon single-row fixation restore insertion site anatomy, with excellent results. We compared the biomechanical properties of double-row and transtendon single-row suture anchor techniques for repair of grade Ⅲ partial articular-sided rotator cuff tears.Methods In 10 matched pairs of fresh-frozen sheep shoulders, the infraspinatus tendon from 1 shoulder was repaired with a double-row suture anchor technique. This comprised placement of 2 medial anchors with horizontal mattress sutures at an angle of .≤45° into the medial margin of the infraspinatus footprint, just lateral to the articular surface, and 2 lateral anchors with horizontal mattress sutures. Standardized, 50% partial, articular-sided infraspinatus lesions were created in the contralateral shoulder. The infraspinatus tendon from the contralateral shoulder was repaired using two anchors with transtendon single-row mattress sutures. Each specimen underwent cyclic loading from 10 to 100 N for 50 cycles, followed by tensile testing to failure. Gap formation and strain over the footprint area were measured using a motion capture system; stiffness and failure load were determined from testing data.Results Gap formation for the transtendon single-row repair was significantly smaller (P <0.05) when compared with the double-row repair for the first cycle ((1.74±0.38) mm vs. (2.86±0.46) mm, respectively) and the last cycle ((3.77±0.45) mm vs. (5.89±0.61) mm, respectively). The strain over the footprint area for the transtendon single-row repair was significantly smaller (P <0.05) when compared with the double-row repair. Also, it had a higher mean ultimate tensile load and stiffness.Conclusions For grade Ⅲ partial articular-sided rotator cuff tears, transtendon single-row fixation exhibited superior biomechanical properties when compared with double-row fixation.

    Shoulder arthrodesis is indicated in infections, brachial paralysis, irreparable rotator cuff tears, osteoarthritis without indication of prosthesis, rescue after arthroplasty, or after surgery for cancer. Arthroscopic arthrodesis is exceptional. Our aim is presenting our result after 14 years of follow-up of one patient. We present a case report of a 17-year-old male patient. He suffered fracture of left scapula (type V, Ideberg), fracture of left clavicle (type I, Craig), and fracture of left distal ulna. We realized osteosynthesis of clavicle (plate and screws) with the aim of treating this floating shoulder. Electromyography showed partial axonotmesis of axilar nerve. After 7 months of follow-up, axonotmesis was still present. We realized arthroscopic shoulder arthrodesis (three cannulated screws). Fourteen years later, shoulder movement was as follows: Flexion, 0-90°; maximum abduction, 40° with shoulder atrophy; Constant, 47 points; and UCLA, 17 points, without pain. Arthrodesis with screws reaches a subjective benefit in 82% of patients. Percentage of pseudarthrosis is less than in patients treated with plates, although the risks of infections, fractures, and material removal are greater than in patients treated with plates. Shoulder arthroscopic arthrodesis is exceptional, but it allows minimal surgical aggression. PMID:21897586

    In a subset of patients with rotator cuff tears, the glenohumeral joint has minimal degenerative changes and the rotator cuff tendon is either irreparable or very poor quality and unlikely to heal. Reverse shoulder arthroplasty (RSA) is often considered for these patients despite the lack of glenohumeral arthritis. However, due to the permanent destruction of the glenohumeral articular surfaces, complication rates, and concerns about implant longevity with RSA, we believe the superior capsular reconstruction (SCR) is a viable alternative. In this article, we describe our technique for the SCR. PMID:27552457

    Arthroscopic microdiskectomy through a posterolateral approach has opened a new window of opportunity in the treatment of lumbar disk disorders. Radiographic identification of the triangular working zone has permitted the safe introduction of instruments with an external diameter of 7-8 mm into the intervertebral disk. The technique allows not only evacuation and decompression of contained herniated disks, but also the introduction of instruments for decortication of the vertebral plates and bone grafting for percutaneous interbody fusion. Endoscopic laser nucleolysis, currently under investigation, may also enhance existing technological achievement in the field of minimal-intervention spinal surgery. Arthroscopic microdiskectomy has proven to be safe, effective, and cost efficient. In properly selected patients, satisfactory results of approximately 85% have been realized. PMID:1857361

    Objective To study the effect of corticosteroid on rat rotator cuff injury healing by observing histological change and quantifying the dynamic change of type Ⅲ collagen. Methods Thirty-six Sprague-Dawley rats were randomly divided into 4 groups:6 rats group A (normal rotator cuff) ,6 rats in group B (rotator cuff injury), 12 rats in group C (normal rotator cuff treated with corticosteroid) ,and 12 rats in group D (rotator cuff injury treated with corticosteroid). In the rats of groups B and D, a partialthickness rotator cuff injury was created by cutting 50% of thickness and 5 mm of width of the bilateral infraspinatus tendon 5 mm from its humeral insertion. 0.05 ml corticosteroid (Diprospan) was injected into the subacromial space of the rats in groups C and D. Total infraspinatus tendons were harvested for HE, Masson staining,immunohistochemical staining and type Ⅲ collagen quantification. Results istological change : In corticosteroid treatment groups, the normal arrangement of the collagen bundles was replaced by the disorganized collagen bundles with fragmentation of the collagen bundles and collagen necrosis at 3rd week, and the arrangement was improved very slightly at 6th week. Type In collagen : ( 1 ) The type Ⅲ collagen levels were significantly increased after the rotator cuff injury ( P < 0.05 ) ; (2) At 3rd week, the type Ⅲ collagen levels in corticoateroid treatment groups were significantly higher than in normal rotator cuff group and rotator cuff injury group ( P < 0.01 ) ; (3) At 6th week, the type Ⅲ collagen levels in rotator cuff injury treated with corticosteroid group remained on a very high level; (4) The type Ⅲ collagen levels in normal rotator cuff treated with corticosteroid group were significantly increased at 3rd week, and returned to the normal at 6th week (P > 0.05). Conclusion Corticosteroid can induce type Ⅲ collagen synthesis during rotator cuff healing, but even a single dose of corticosteriod can cause

    Full Text Available Abstract Background Chronic rotator cuff pathology (CRCP is a common shoulder condition causing pain and disability. Physiotherapy is often the first line of management for CRCP yet there is little conclusive evidence to support or refute its effectiveness and no formal evaluation of its cost-effectiveness. Methods/Design This randomised, double-blind, placebo-controlled trial will involve 200 participants with CRCP recruited from medical practices, outpatient departments and the community via print and radio media. Participants will be randomly allocated to a physiotherapy or placebo group using concealed allocation stratified by treating physiotherapist. Both groups will receive 10 sessions of individual standardised treatment over 10 weeks from one of 10 project physiotherapists. For the following 12 weeks, the physiotherapy group will continue a home exercise program and the placebo group will receive no treatment. The physiotherapy program will comprise shoulder joint and spinal mobilisation, soft tissue massage, postural taping, and home exercises for scapular control, posture and rotator cuff strengthening. The placebo group will receive inactive ultrasound and gentle application of an inert gel over the shoulder region. Blinded assessment will be conducted at baseline and at 10 weeks and 22 weeks after randomisation. The primary outcome measures are self reported questionnaires including the shoulder pain and disability index (SPADI, average pain on an 11-point numeric rating scale and participant perceived global rating of change. Secondary measures include Medical Outcomes Study 36-item short form (SF-36, Assessment of Quality of Life index, numeric rating scales for shoulder pain and stiffness, participant perceived rating of change for pain, strength and stiffness, and manual muscle testing for shoulder strength using a handheld dynamometer. To evaluate cost-effectiveness, participants will record the use of all health

    BACKGROUND: More and more patients who have crushing and serious shift proximal humeral fractures that cannot be reconstructed need artificial humeral head replacement. However, the rotator cuff reconstruction may directly affect surgical effect. Thus, better rotator cuff reconstruction is needed during replacement. OBJECTIVE: To investigate application value of sternum needles in rotator cuff reconstruction of proximal humeral fractures during artificial humeral head replacement. METHODS: Thirty-four cases of four-part proximal humeral fractures received rotator cuff repairing with sternum needles during artificial humeral head replacement, at the age between 67 and 78 years. Artificial humeral head replacement was performed without excessive peeling fracture block or rotator cuff tissue to retain the rotator cuff tissue and bone connected, and then the sternum needle was used to ringclosure the nodules along the surface of the rotator cuff tendon-bone junction for reverse, sternum needle could be used more than one. After prosthesis implantation, anatomic reduction of the large and smal nodules of humerus and bone fragments was performed, and then the sternum needle was tightened; the large and smal nodules and rotator cuff attached bone fragments were affixed to the bottom of the humeral head in situ. Operation should maximal y suture the residual rotator cuff and damaged muscle tissue, and should pay attention to the dynamic equilibrium after suture. The recovery of artificial shoulder joint function was evaluated with Neer criteria. RESULTS AND CONCLUSION: Al the patients were fol owed-up for 1-3 years, and the results showed excel ent in 24 cases, good in 10 cases and average in two cases. No joint dislocation, subluxation and joint instability, and no infections, nerve injury or prosthesis loosening were observed.

    2016-01-01

    ABSTRACT Background and Purpose Rotator cuff tendinopathy (RTCT) is regularly treated by the physical therapist. Multiple etiologies for RTCT exist, leading an individual to seek treatment from their provider of choice. Strengthening exercises (SE) have been reported to be effective in the treatment of RTCT, but there is limited evidence on the effectiveness of dry needing (DN) for this condition. The purpose of this retrospective case series was to investigate DN to various non-trigger point-based anatomical locations coupled with strengthening exercises (SE) as a treatment strategy to decrease pain and increase function in healthy patients with chronic RTC pathology. Case Descriptions Eight patients with RTCT were treated 1-2 times per week for up to eight weeks, and no more than sixteen total treatment sessions of SE and DN. Outcomes were tested at baseline and upon completion of therapy. A long-term outcome measure follow up averaging 8.75 months (range 3 to 20 months) was also performed. The outcome measures included the Visual Analog Scale (VAS) and the Quick Dash (QD). Outcomes Clinically meaningful improvements in disability and pain in the short term and upon long-term follow up were demonstrated for each patient. The mean VAS was broken down into best (VASB), current (VASC), and worst (VASW) rated pain levels and the mean was calculated for the eight patients. The mean VASB improved from 22.5 mm at the initial assessment to 2.36 mm upon completion of the intervention duration. The mean VASC improved from 28.36 mm to 5.0 mm, and the mean VASW improved from 68.88 mm to 13.25 mm. At the long-term follow up (average 8.75 months), The mean VASB, VASC, and VASW scores were 0.36 mm, 4.88 mm, and 17.88 mm respectively. The QDmean for the eight patients improved from 43.09 at baseline to 16.04 at the completion of treatment. At long-term follow-up, the QDmean was 6.59. Conclusion Clinically meaningful improvements in pain and disability were

    Objectives: Recent publications have highlighted the relatively poor outcome of other overhead athletes, particularly baseball players, with regard to return to sports at the same or higher level after shoulder surgery. However, true assessment of their ability when returning to sport is not as clear. Further, ability to return to other overhead sports has not been reported. Our objective was to assess outcome and time to return to previous level of function following shoulder surgery in professional tennis players. Methods: The records of all female tennis players on the Women’s Tennis Association (WTA) professional circuit between January 2008 and June 2010 were reviewed to identify players who underwent shoulder surgery on their dominant (serving) shoulder. Details of the surgery including date, procedures performed, and complications were recorded. The primary outcomes were ability and time to return to professional play, and if they were able to return to their previous level of function, as determined by singles ranking. Pre and post-operative singles rankings were used to determine rate and completeness of return to preoperative function. Their highest ranking pre-injury, post operatively, and the time to return to pre-injury ranking were evaluated. Results: During the study period eight professional women tennis players from the WTA underwent shoulder surgery on their dominant arm. All surgery was performed arthroscopically, 7 out of 8 players had more than one procedure performed during the surgery. In total, 3 players underwent debridement of a partial rotator cuff tear and 2 players underwent repair of a complete supraspinatus tear. Three players had an anterior labral repair or reconstruction for anterior instability, and one player underwent repair of a SLAP lesion. Two players underwent neurolysis of a suprascapular nerve, and three players in total underwent a subacromial decompression. All players (100%) returned to professional play. The mean

Disorders of the shoulder muscles and tendons (rotator cuff are thought to be the commonest cause of this pain. The long-term outcome is frequently poor despite treatment. This means that many patients are exposed to more invasive treatment, e.g. surgery, and/or long-term pain and disability. Patients with this disorder typically receive a course of physiotherapy which might include a range of treatments. Specifically the value of exercise against gravity or resistance (loaded exercise in the treatment of tendon disorders is promising but appears to be under-used. Loaded exercise in other areas of the body has been favourably evaluated but further investigation is needed to evaluate the impact of these exercises in the shoulder and particularly the role of home based or supervised exercise versus usual treatment requiring clinic attendance. Methods/Design A single-centre pragmatic unblinded parallel group randomised controlled trial will evaluate the effectiveness of a self-managed loaded exercise programme versus usual clinic based physiotherapy. A total of 210 study participants with a primary complaint of shoulder pain suggestive of a rotator cuff disorder will be recruited from NHS physiotherapy waiting lists and allocated to receive a programme of self-managed exercise or usual physiotherapy using a process of block randomisation with sealed opaque envelopes. Baseline assessment for shoulder pain, function and quality of life will be undertaken with the Shoulder Pain & Disability Index, the Patient Specific Functional Scale and the SF-36. Follow-up evaluations will be completed at 3, 6 and 12 months by postal questionnaire. Both interventions will be delivered by NHS Physiotherapist’s. An economic analysis will be conducted from an

    Full Text Available Background/Aim. Meniscal injuries are common in professional or recreational sports as well as in daily activities. If meniscal lesions lead to physical impairment they usually require surgical treatment. Arthroscopic treatment of meniscal injuries is one of the most often performed orthopedic operative procedures. Methods. The study analyzed the results of arthroscopic partial medial meniscectomy in 213 patients in a 24-month period, from 2006, to 2008. Results. In our series of arthroscopically treated medial meniscus tears we noted 78 (36.62% vertical complete bucket handle lesions, 19 (8.92% vertical incomplete lesions, 18 (8.45% longitudinal tears, 35 (16.43% oblique tears, 18 (8.45% complex degenerative lesions, 17 (7.98% radial lesions and 28 (13.14% horisontal lesions. Mean preoperative International Knee Documentation Committee (IKDC score was 49.81%, 1 month after the arthroscopic partial medial meniscectomy the mean IKDC score was 84.08%, and 6 months after mean IKDC score was 90.36%. Six months after the procedure 197 (92.49% of patients had good or excellent subjective postoperative clinical outcomes, while 14 (6.57% patients subjectively did not notice a significant improvement after the intervention, and 2 (0.93% patients had no subjective improvement after the partial medial meniscectomy at all. Conclusion. Arthroscopic partial medial meniscetomy is minimally invasive diagnostic and therapeutic procedure and in well selected cases is a method of choice for treatment of medial meniscus injuries when repair techniques are not a viable option. It has small rate of complications, low morbidity and fast rehabilitation.

    Full Text Available Abstract Purpose Both open and arthroscopic Bankart repair are established procedures in the treatment of anterior shoulder instability. While the open procedure is still considered as the "golden standard" functional outcome is supposed to be better in the arthroscopic procedure. The aim of this retrospective study was to compare the functional outcome between open and arthroscopic Bankart repair. Materials and methods In 199 patients a Bankart procedure with suture anchors was performed, either arthroscopically in presence of an detached, but not elongated capsulolabral complex (40 or open (159. After a median time of 31 months (12 to 67 months 174 patients were contacted and agreed to follow-up, 135 after open and 39 after arthroscopic Bankart procedure. Results Re-dislocations occurred in 8% after open and 15% after arthroscopic Bankart procedure. After open surgery 4 of the 11 re-dislocations occurred after a new adequate trauma and 1 of the 6 re-dislocations after arthroscopic surgery. Re-dislocations after arthroscopic procedure occured earlier than after open Bankart repair. An external rotation lag of 20° or more was observed more often (16% after open than after arthroscopic surgery (3%. The Rowe score demonstrated "good" or "excellent" functional results in 87% after open and in 80% patients after arthroscopic treatment. Conclusion In this retrospective investigation the open Bankart procedure demonstrated good functional results. The arthroscopic treatment without capsular shift resulted in a better range of motion, but showed a tendency towards more frequently and earlier recurrence of instability. Sensitive patient selection for arthroscopic Bankart repair is recommended especially in patients with more than five dislocations.

    Full Text Available Abstract Background This study evaluates the preoperative conventional anteroposterior radiography and clinical testing in non-operated patients with cuff tear arthropathy. It analyses the radiological findings in relation to the status of the rotator cuff and clinical status as also the clinical testing in relation to the rotator cuff quality. The aim of the study is to define the usefulness of radiography and clinical examination in cuff tear arthropathy. Methods This study analyses the preoperative radiological (AP-view, (Artro-CT-scan or MRI-scan and clinical characteristics (Constant-Murley-score plus active and passive mobility testing and the peroperative findings in a cohort of 307 patients. These patients were part of a multicenter, retrospective, consecutive study of the French Orthopaedic Society (SOFCOT-2006. All patients had no surgical antecedents and were all treated with prosthetic shoulder surgery for a painful irreparable cuff tear arthropathy (reverse-(84% or hemi-(8% or double cup-bipolar prosthesis (8%. Results A positive significancy could be found for the relationship between clinical testing and the rotator cuff quality; between acromiohumeral distance and posterior rotator cuff quality; between femoralization and posterior rotator cuff quality. Conclusion A conventional antero-posterior radiograph can not provide any predictive information on the clinical status of the patient. The subscapular muscle can be well tested by the press belly test and the teres minor muscle can be well tested by the hornblower' sign and by the exorotation lag signs. The upward migration index and the presence of femoralization are good indicators for the evaluation of the posterior rotator cuff. An inferior coracoid tip positioning suggests rotator cuff disease.

    International Nuclear Information System (INIS)

    Luxatio erecta or inferior glenohumeral dislocation is a rare type of shoulder dislocation, accounting for less than 1 % of all reported shoulder dislocations. We describe a 15-year-old male who presented with luxatio erecta following an injury to his shoulder that resulted from a mountain biking accident. Clinically, the patient had shoulder pain and fixed abduction of the arm. Radiographs confirmed the diagnosis of luxatio erecta. A magnetic resonance arthrogram (MRA) performed 9 days after presentation demonstrated both a greater tuberosity fracture and avulsion of the anterior and posterior inferior glenohumeral ligaments from their humeral attachment. The MR findings were confirmed on arthroscopy. The bone and soft tissue injury pattern seen in our patient clearly supports the described mechanism of injury for luxatio erecta and lends credence to the theory that a fracture of the greater tuberosity spares injury to the rotator cuff, especially in children. A review of the literature failed to reveal any prior description of the MRI or MRA findings of luxatio erecta in a pediatric patient or any publication with arthroscopic confirmation of the MR findings.

    1985-01-01

    A flexible connector apparatus used to join two stiff non-deformable members, such as piping. The apparatus is provided with one or more flexible sections or assemblies each utilizing a bellows of a rolling cuff type connected between two ridge members, with the bellows being supported by a back-up ring, such that only the curved end sections of the bellows are unsupported. Thus, the bellows can be considered as being of a tube-shaped configuration and thus have high pressure resistance. The components of the flexible apparatus are sealed or welded one to another such that it is fluid tight.

  18. Dynamic enhanced MRI of the subacromial bursa: correlation with arthroscopic and histological findings

    International Nuclear Information System (INIS)

    Objective: To assess dynamic MRI with Gd-DTPA enhancement for evaluating inflammatory changes in the subacromial bursa. Design and patients: We detected the signal intensity changes in dynamic MRI of the subacromial bursa, and confirmed these macroscopically by arthroscopy and histologically. The signal intensity was measured using built-in software, and the enhancement ratio (E ratio) was calculated from dynamic MR images. In addition, as a parameter of the rate of the increase in the signal intensity from 0 to 80 s, the mean increase per second in the E ratio was obtained as the coefficient of enhancement (CE). The correlation was studied of the E ratio and CE with the arthroscopic findings (redness, villous formation, thickening and adhesion), and of the E ratio and CE with the histological findings (capillary proliferation, papillary hyperplasia, fibrosis and inflammatory cell infiltration) of the subacromial bursa. Of patients with shoulder pain, this study included those with rotator cuff injury; patients with rheumatoid arthritis or pitching shoulder disorders were excluded. There were 27 patients (15 men, 12 women) ranging in age from 25 to 73 years (mean 49.1 years). Dynamic MRI of the shoulder was also performed on the healthy side of 10 patients and in five normal young volunteers. Results and conclusions: Changes in signal intensity on dynamic MRI were measured in the subacromial bursa. The E ratio (80 s) and CE (0-80 s) were significantly correlated with redness and villous formation as arthroscopic findings, positively correlated with capillary proliferation and papillary hyperplasia as histological findings (p < 0.05), and negatively correlated with fibrosis as a histological finding (p < 0.05) in the subacromial bursa. The patterns of dynamic curves were well correlated with the bursoscopic and histological findings of the synovium of the subacromial bursa.

    2013-05-01

    Labral tears in the hip may cause painful clicking or locking of the hip, reduced range of motion, and disruption to sports and daily activities. The acetabular labrum aids stabilization of the hip joint, particularly during hip motion. The fibrocartilaginous structure extends the acetabular rim and provides a suction seal around the femoroacetabular interface. Treatment options for labral tears include debridement, repair, and reconstruction. Repair of the labrum has been shown to have better results than debridement. Labral refixation is achieved with sutures anchored into the acetabular rim. The acetabular rim is trimmed either to correct pincer impingement or to provide a bleeding bed to improve healing. Labral repair has shown excellent short-term to midterm outcomes and allows patients to return to activities and sports. Arthroscopic rim trimming and labral refixation comprise an effective treatment for labral tears with an underlying diagnosis of femoroacetabular impingement and are supported by the peer-reviewed literature.

    Background Partial rotator cuff tears result in pain and disfunction in patients.An previous study,the researchers measured the supraspinatus tendon of 1 7 corpses and came to a conclusion that the average thickness of the supraspinatus tendon was 1 2 mm.Divides the rotator cuff tears into partial articular tears,partial bursa tears and intra-tendon tears according to the inj ury sites. Based on the thickness of inj ured rotator cuff measured during the operation,the tears are divided into 3 degrees:Degree I (≤3 mm),Degree Ⅱ (3-6 mm)and Degree Ⅲ (≥ 6 mm),and the injured thickness of the Degree Ⅲ is more than 50%.Waibl et al put forward the concept of partial articular surface tendon avulsions(PASTA)and the trans-tendon approach to repair the inj ury.The PASTA has a high morbidity.Modi et al reviewed 100 cases who were all over 35 years old.They recieved an arthroscopic surgery for rotator cuff lesions.Waibl then found 62 cases had PASTA.Yamanaka et al followed 40 PASTA patients using arthrography,the average follow-up was 412 days.They found that the PASTA had a tendency to expand (53%)and to progress to full-thickness tears (28%).Take this into account,most scholars tend to endorse the decision that tears over degree Ⅲ must be repaired.The methods include the conventional repair after the conversion of the full-thickness tear and the direct repair of the tears using the tendon approach.Compared with the former,the tendon repair can save the residual normal rotator cuff tissue,and the length-tension balance after rotator cuff repair is simmilar to normal anatomy.Up to now,China is still lack of treatment reports for such reported inj uries.From March 2008 to July 2010,we had 12 cases of patients with PASTA who recieved the arthroscopic trans-tendon repair using the method improved by Lo.All patients were followed up for 1 2 months or more,and the results are as follows.Methods I.General Information:There are 1 2 cases in the group, including 5 males,7

    Continuous use of wearable robots can cause skin injuries beneath the cuffs of robots. To prevent such injuries, understanding the contact behavior of the cuff is important. Thus far, this contact behavior has not been studied because of the difficulty involved in measuring the slippage under the cuff. In this study, for the first time, the relative displacement, slippage, and interaction force and moment at the thigh cuff of a robot during sit-to-stand motion were measured using an instrumented cuff, which was developed for this purpose. The results indicated that the slippage and relative displacement under the cuff was uneven because of the rotation of the cuff, which suggests that the risk of skin injuries is different at different positions. Especially, the skin closer to the hip showed larger dynamism, with a maximum slippage of approximately 10 mm and a displacement of 20 mm during motion. Another important phenomenon was the individual difference among subjects. During motion, the interaction force, moment, and slippage of some subjects suddenly increased. Such behavior results in stress concentration, which increases the risk of skin injuries. These analyses are intended to understand how skin injuries are caused and to design measures to prevent such injuries. PMID:26276994

  13. Cuff width alters the amplitude envelope of wrist cuff pressure pulse waveforms

    International Nuclear Information System (INIS)

    The accuracy of noninvasive blood pressure (BP) measurement with any method is affected by cuff width. Measurement with a too narrow cuff overestimates BP and measurement with a too wide cuff underestimates BP. Automatic wrist cuff BP monitors use permanently attached narrow cuffs with bladders about 6 cm wide. Such narrow cuffs should result in under-cuffing for wrist circumferences larger than 15 cm. The objective of this qualitative study was to show that a narrow wrist cuff results in increased BP values when a cuff pulse amplitude ratio algorithm is used. According to the algorithm used in this study, systolic pressure (SBP) corresponds to the point of 50% of maximal amplitude; for diastolic pressure (DBP) the ratio is 70%. Data were acquired from 12 volunteers in the sitting position. The mean wrist circumference was 18 cm. The acquired cuff pulse data were used to compute SBP, mean pressure (MAP) and DBP. The mean values for a 6 cm cuff were SBP = 144 mmHg, MAP = 104 mmHg and DBP = 88 mmHg. The values for a 10 cm cuff were SBP = 128 mmHg, MAP = 93 mmHg and DBP = 78 mmHg. The reference BP values were SBP = 132 mmHg, MAP = 96 mmHg and DBP = 80 mmHg. All narrow (6 cm) cuff BP values were higher than wide (10 cm) cuff or reference BP values. The results indicate that wider wrist cuffs may be desirable for more accurate and reliable BP measurement with wrist monitors. (note)

    Lambert, D.R.

    1982-09-27

    A flexible connector apparatus used to join two stiff non-deformable members, such as piping, is described. The apparatus is provided with one or more flexible sections or assemblies each utilizing a bellows of a rolling cuff type connected between two ridge members, with the bellows being supported by a back-up ring, such that only the curved end sections of the bellows are unsupported. Thus, the bellows can be considered as being of a tube-shaped configuration and thus have high pressure resistance. The components of the flexible apparatus are sealed or welded one to another such that it is fluid tight.

    2015-01-01

    Full Text Available Recently, although some studies of open repair of the tendon of the quadriceps femoris have been published, there have been no reports in the literature on primary arthroscopic repair. In our present study, we present two cases of quadriceps tendon injury arthroscopically repaired with excellent results. Case 1 involved a 68-year-old man who was injured while shifting his weight to prevent a fall. MRI showed complete rupture at the insertion of the patella of the quadriceps tendon. The rupture was arthroscopically repaired using both suture anchor and pull-out suture fixation methods via bone tunnels (hereafter, pull-out fixation. Two years after surgery, retearing was not observed on MRI and both Japan Orthopedic Association (JOA Knee and Lysholm scores had recovered to 100. Case 2 involved a 50-year-old man who was also injured when shifting his weight to prevent a fall. MRI showed incomplete superficial rupture at the insertion of the patella of the quadriceps tendon. The rupture was arthroscopically repaired using pull-out fixation of six strand sutures. One year after surgery, MRI revealed a healed tendon and his JOA and Lysholm scores were 95 and 100, respectively. Thus, arthroscopic repair may be a useful surgical method for repairing quadriceps tendon injury.

    Endotracheal tube (ETT) cuff pressure management is an essential part of airway management in intubated and mechanically ventilated patients. Both under- and over-inflation of the ETT cuff can lead to patient complications, with an ideal pressure range of 20-30 cmH2O defined. A range of techniques are employed to ensure adequate ETT cuff inflation, with little comparative data. We performed an observational cross-sectional study in a tertiary metropolitan ICU, assessing the relationship between the minimal leak test and cuff manometry. Forty-five mechanically ventilated patients, over a three-month period, had ETT cuff manometry performed at the same time as their routine cuff maintenance (minimal leak test). Bedside nurse measurements were compared with investigator measurements. At the endpoint of cuff inflation, 20 of 45 patients (44%) had cuff pressures between 20 and 30 cmH2O; 11 of 45 patients (24%) had cuff pressures 2O; 14 of 45 patients (31%) had cuff pressures ≥30 cmH2O. Univariate analysis demonstrated an association between both patient obesity and female gender requiring less ETT cuff volume (P=0.008 and P cuff pressures. Inter-operator reliability in performing the minimal leak test showed no evidence of bias between nurse and investigators (Pearson coefficient = 0.897). We conclude the minimal leak test for maintenance of ETT cuffs leads to both over- and under-inflation, and alternative techniques, such as cuff manometry, should be employed. PMID:27608343

    Full Text Available OBJECTIVE: The purpose of this manuscript is to review current knowledge of how muscle activation and force production contribute to shoulder kinematics in healthy subjects and persons with shoulder impingement. RESULTS: The middle and lower serratus anterior muscles produce scapular upward rotation, posterior tilting, and external rotation. Upper trapezius produces clavicular elevation and retraction. The middle trapezius is primarily a medial stabilizer of the scapula. The lower trapezius assists in medial stabilization and upward rotation of the scapula. The pectoralis minor is aligned to resist normal rotations of the scapula during arm elevation. The rotator cuff is critical to stabilization and prevention of excess superior translation of the humeral head, as well as production of glenohumeral external rotation during arm elevation. Alterations in activation amplitude or timing have been identified across various investigations of subjects with shoulder impingement as compared to healthy controls. These include decreased activation of the middle or lower serratus anterior and rotator cuff, delayed activation of middle and lower trapezius, and increased activation of the upper trapezius and middle deltoid in impingement subjects. In addition, subjects with a short resting length of the pectoralis minor exhibit altered scapular kinematic patterns similar to those found in persons with shoulder impingement. CONCLUSION: These normal muscle functional capabilities and alterations in patient populations should be considered when planning exercise approaches for the rehabilitation of these patients.OBJETIVO: O objetivo deste manuscrito é revisar o conhecimento atual sobre como a ativação muscular e a produção de força contribuem para a cinemática do ombro em indivíduos saudáveis e em pessoas com síndrome do impacto.

    Objectives: The primary objective of this study was to determine if quality of life and function are different following arthroscopic versus open tennis elbow release surgery. Based on retrospective studies, both approaches have been found to be beneficial, but no prospective randomized comparison has been conducted to date. Methods: Following a minimum six-months of conservative treatment, seventy-one patients (>16 yrs old) were randomized intraoperatively to undergo either arthroscopic or open lateral release. Outcome measures were the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), a 5-question VAS Pain Scale, and grip strength. Study assessments took place pre-, and 6-week, 3-, 6-, and 12-months post-surgery. Comparisons between groups and within groups over time were conducted using repeated measures ANOVA. A minimal clinically significant difference for the DASH had been previously identified as 15 points, and was used to compare groups as well at 12-months post-operative (Beaton et al. 2001). Results: Fifteen women and 19 men underwent the open procedure with a mean age of 47.1 years (6.7) and 13 women and 21 men were in the arthroscopic group with a mean age of 45.0 (6.9). No pre-surgery differences were found between groups based on age, sex, DASH or VAS scores. Both groups demonstrated a significant improvement in subjective measures and grip strength by 12-months post-surgery, and no significant differences were found between groups at any time point. The DASH, our primary outcome, decreased from a mean (SD) of 47.5 (14.5) pre-surgery to 21.9 (21.8) at 12-months post-surgery in the Open group and from 52.7 (16.0) to 22.6 (21.1) in the Arthroscopic group. VAS-pain scores (%) decreased in the Open group from 62.5 (17.2) pre-operatively to 30.0 (26.5) at 12-months. In the arthroscopic group, scores decreased from 63.7 (15.9) to 26.2 (24.6). Grip strength (kg) increased on the affected side from 23.6 (14.9) to 29.3 (16.3) and 21.4 (15.4) to

    Objective To evaluate the results of rotational acetabular osteotomy (RAO) combined with debridement under arthroscope in the treatment of adult developmental dysplasia of the hip (DDH). Methods Between April 2002 and August 2007,24 cases (29 hips) of DDH were treated with RAO combined with debridement under arthroscope. There were 2 males (2 hips) and 22 females (27 hips) with an average age of 37.7 years (range, 21-50 years). The locations were the left hip in 7 cases, the right hip in 12 cases, and both hips in 5 cases. The course of hip pain was 8-216 months (median, 30.5 months). According to Crowe DDH classification, there were 24 hips of type I and 5 hips of type II. According to T8nnis hip osteoarthritis classification, there were 20 hips of stage I and 9 hips of stage II. Results The mean operation time was 150 minutes (range, 120-180 minutes); the mean intraoperative blood loss was 600 mL (range, 500-700 mL); and the mean postoperative drainage volume was 200 mL(range, 50-400 mL). All incisions healed by first intention. Twenty-four cases were followed up 4.5 years on average (range, 3-8 years). At last follow-up, daudication disappeared in 16 hips and was improved in 8 hips. The Harris hip score was improved from 79.4 ± 9.8 preoperatively to 95.1 ± 8.6 postoperatively, showing significant difference (t=2.467, P=0.010). The visual analogue scale (VAS) score was improved from 5.1 ± 0.8 preoperatively to 1.1 ± 0.6 postoperatively, showing significant difference (t=2.118, P=0.011). The X-ray films showed union was achieved at 12-16 weeks (mean, 13.5 weeks). There were significant differences in the centre edge angle, Sharp angle, acetabular coverage rate, and acetabulum-head index between preoperation and postoperation (P < 0.05). Twenty hips at Tennis stage I maintained after operation, among 9 hips at Tsnnis stage II, 5 hips was improved to stage I and 4 hips maintained. Conclusion It has a satisfactory result to treat adult DDH by RAO combined with

    Arthroscopically assisted treatments for dislocations of the acromioclavicular joint combine the advantages of exact and visually controlled coracoid tunnel placement with the possibility of simultaneous treatment of concomitant injuries. The clinical results of previous arthroscopically assisted techniques have been favorable at midterm and long-term follow-up. The presented surgical technique combines the advantages of arthroscopically positioned coracoclavicular stabilization with an additional suture cord cerclage of the acromioclavicular joint capsule for improved horizontal stability.

  15. COMPARATIVE STUDY OF SUBMENTAL INTUBATION CUFF IN VS CUFF OUT: A CASE SERIES

    Directory of Open Access Journals (Sweden)

    Aprajita

    2016-06-01

    Full Text Available In patients with panfacial trauma where short-term intraoperative control of airway is required, submental intubation is an alternative to tracheostomy as it is associated with lesser morbidity. It is also an interesting alternative to oral and nasal intubation as intraoperatively the tube does not cause any hindrance to the surgeon and occlusion can also be assessed simultaneously. Out of 10 cases of maxillofacial trauma operated in our hospital using submental intubation, the cuff of the pilot tube was brought out in 5 of them through the midline incision, while in remaining 5 it was left inside the nasopharynx. It was observed subsequently that cuff inside the nasopharynx had some advantage, viz. there were lesser chances of accidental extubation, rupture of cuff and the incision size need not be extended to extract the cuff which resulted into a cosmetically better scar.

    Objectives: The shoulder is the most common joint dislocation effecting roughly 2% of the general population. Males are effected to a higher degree that females at a ratio of 3:1.1-2 The young, athletic population make up the largest portion of shoulder instability, and treated nonoperatively have a recurrent dislocation rate approaching 50%.3-5 Owens et. al recently published a cohort looking at 45 college athletes with an in season shoulder instability event. 73% of athletes returned to play in season. Only 36% of athletes completed the season without re-injury and 64% of athletes had a recurrent instability event.6 It is unknown how the outcomes of those who go on to have a recurrent dislocation in season are effected versus those who have a stabilization procedure after a first time dislocation. The objective of the current study is to report the postoperative outcomes of first time dislocators versus patients with recurrent dislocations prior to surgery. Methods: CPT codes were used to identify patients who had arthroscopic Bankart repair between 2003-2013. 439 patients aged 16-30 years were identified across 8 fellowship trained surgical practices. The first phase of the study was a retrospective chart review to obtain patient demographics, number of reported preoperative dislocations, review imaging, and number of anchors placed. Patients were identified as first time dislocators or as recurrent dislocators when they had more than one dislocation prior to surgical intervention. The second phase consisted of a survey to obtain a simple shoulder test score, whether they returned to sport, postoperative instability events and further surgery on the shoulder. Postoperative instability was defined as a subluxation or dislocation reported by the patient survey in the postoperative period. Of the 439 patients identified, 296 were excluded for revision surgery, open repair, posterior instability, multidirectional instability, HAGL lesion, labral tears involving the

    Full Text Available Background: The Bankart lesion represents the most common form of labro-ligamentous injury in patients with traumatic dislocations of the shoulder leading to shoulder instability. We report the clinical outcome of arthroscopic repair of Bankart lesion in 50 patients. Materials and Methods: Sixty five patients with posttraumatic anterior dislocation of shoulder were treated by arthroscopic repair from Jan 2005 to Nov 2008. Fifty patients, with an average age of 26.83 years (range 18-45 years, were reviewed in the study. The average followup period was 27 months (range 24-36 months. University of California Los Angeles shoulder rating scale was used to determine the outcome after surgery. The recurrence rates, range of motion, as well as postoperative function and return to sporting activities were evaluated. Results : Thirty six patients (72.0% had excellent results, whereas seven patients (14.0% had good results. The mean pre- and postoperative range of external rotation was 80.38° and 75.18°, respectively. Eighty-six percent patients had stability compared with the normal sided shoulder and were able to return to sports. There were no cases of redislocation observed in this study; however, three cases had mild laxity of the joint. Conclusion: Arthroscopic Bankart repair with the use of suture anchors is a reliable treatment method, with good clinical outcomes, excellent postoperative shoulder motion and low recurrence rates.

    Full Text Available Background: Arthroscopy of the great toe MTP joint has been practiced with favourable outcomes. A range of indications have been described ranging from synovitis to osteochondral defects. The purpose of the present study was to describe our technique and to assess the functional outcome following arthroscopic management of Hallux MTP disorders using AOFAS scoring system. Methods: We describe the technique of Hallux MTP joint arthroscopy in twenty patients. Indications included hallux rigidus with osteophytes, chondromalacia, OCDs, loose bodies, arthrofibrosis, synovitis, tophaceous gout arthritis and intra-articular fractures of MTP joint. All patients had been evaluated clinically and radiologically with record of their AOFAS scores pre-operatively. At a minimum follow-up of two years the clinical assessment was carried out with AOFAS scores. Results: The mean pre-operative and post-operative AOFAS score were 47 (range 10-78 and 97 (87 -100 respectively. The patient with intra-articular fracture had an excellent outcome following arthroscopic reduction of the fracture. Conclusion: Arthroscopic management of painful hallucial MTP joint is a specialized technique, which if performed for the right indications, gives a favourable outcome with minimal complications.

    Arterial hypotension can be induced by sudden release of inflated thigh cuffs (THC), but its effects on the cerebral circulation have not been fully described. In nine healthy subjects [aged 59 (9) yr], bilateral cerebral blood flow velocity (CBFV) was recorded in the middle cerebral artery (MCA), noninvasive arterial blood pressure (BP) in the finger, and end-tidal CO2 (ETCO2) with nasal capnography. Three THC maneuvers were performed in each subject with cuff inflation 20 mmHg above systolic BP for 3 min before release. Beat-to-beat values were extracted for mean CBFV, BP, ETCO2 , critical closing pressure (CrCP), resistance-area product (RAP), and heart rate (HR). Time-varying estimates of the autoregulation index [ARI(t)] were also obtained using an autoregressive-moving average model. Coherent averages synchronized by the instant of cuff release showed significant drops in mean BP, CBFV, and RAP with rapid return of CBFV to baseline. HR, ETCO2 , and ARI(t) were transiently increased, but CrCP remained relatively constant. Mean values of ARI(t) for the 30 s following cuff release were not significantly different from the classical ARI [right MCA 5.9 (1.1) vs. 5.1 (1.6); left MCA 5.5 (1.4) vs. 4.9 (1.7)]. HR was strongly correlated with the ARI(t) peak after THC release (in 17/22 and 21/24 recordings), and ETCO2 was correlated with the subsequent drop in ARI(t) (19/22 and 20/24 recordings). These results suggest a complex cerebral autoregulatory response to the THC maneuver, dominated by myogenic mechanisms and influenced by concurrent changes in ETCO2 and possible involvement of the autonomic nervous system and baroreflex.

  7. On cuff imbalance and tripolar ENG amplifier configurations.

    Electroneurogram (ENG) recording techniques benefit from the use of tripolar cuffs because they assist in reducing interference from sources outside the cuff. However, in practice the performance of ENG amplifier configurations, such as the quasi-tripole and the true-tripole, has been widely reported to be degraded due to the departure of the tripolar cuff from ideal behavior. This paper establishes the presence of cuff imbalance and investigates its relationship to cuff asymmetry, cuff end-effects and interference source proximity. The paper also presents a comparison of the aforementioned amplifier configurations with a new alternative, termed the adaptive-tripole, developed to automatically compensate for cuff imbalance. The output signal-to-interference ratio of the three amplifier configurations were compared in vivo for two interference signals (stimulus artifact and M-wave) superimposed on compound action potentials. The experiments showed (for the first time) that the two interference signals result in different cuff imbalance values. Nevertheless, even with two distinct cuff imbalances present, the adaptive-tripole performed better than the other two systems in 61.9% of the trials. PMID:15709669

The cuff also has a deflated profile that may allow for easier insertion through the stoma site. This unique design is known as the TaperGuard™ cuff. The purpose of the observational, in vitro study reported here was to compare the TaperGuard™ taper-shaped cuff to a conventional high-volume low-pressure cylindrical-shaped cuff (Shiley™ Disposable Inner Cannula Tracheostomy Tube [DCT] with respect to applied tracheal wall pressure, air and fluid sealing efficacy, and insertion force.Methods: Three sizes of tracheostomy tubes with the two cuff types were placed in appropriately sized tracheal models and lateral wall pressure was measured via pressure-sensing elements on the inner surface. Fluid sealing performance was assessed by inflating the cuffs within the tracheal models (25 cmH2O, instilling water above the cuff, and measuring fluid leakage past the cuff. To measure air leak, tubes were attached to a test lung and ventilator, and leak was calculated by subtracting the average exhaled tidal volume from the average delivered tidal volume. A tensile test machine was used to measure insertion force for each tube with the cuff deflated to simulate clinical insertion through a stoma site.Results: The average pressure exerted on the lateral wall of the model trachea was lower for the taper-shaped cuff than for the cylindrical cuff under all test conditions (P<0.05.

    Full Text Available ABSTRACTOBJECTIVE: To report the clinical and functional results from arthroscopic release of the short radial extensor of the carpus (SREC in patients with chronic lateral epicondylitis that was refractory to conservative treatment. METHODS: Over the period from January 2012 to November 2013, 15 patients underwent arthroscopic treatment. The surgical technique used was the one described by Romeo and Cohen, based on anatomical studies on cadavers. The inclusion criteria were that the patients needed to present lateral epicondylitis and that conservative treatment (analgesics, anti-inflammatory agents, corticoid infiltration or physiotherapy had failed over a period of more than six months. The patients were evaluated based on the elbow functional score of the Mayo Clinic, Nirschl's staging system and a visual analog scale (VAS for pain. RESULTS: A total of 15 patients (9 men and 6 women were included. The mean Mayo elbow functional score after the operation was 95 (ranging from 90 to 100. The pain VAS improved from a mean of 9.2 before the operation to 0.64 after the operation. On Nirschl's scale, the patients presented an improvement from a mean of 6.5 before the operation to approximately one. There were significant differences from before to after the surgery for the three functional scores used ( p 0.05. CONCLUSION: Arthroscopic treatment for lateral epicondylitis was shown to be a safe and effective therapeutic option when appropriately indicated and performed, in refractory cases of chronic lateral epicondylitis. It also allowed excellent viewing of the joint space for diagnosing and treating associated pathological conditions, with a minimally invasive procedure.

    Arthroscopy has become indispensable for performing tibiotalar and subtalar arthrodesis. Now in 2015, it is the gold-standard surgical technique, and open surgery is reserved only for cases in which arthroscopy is contraindicated: material ablation after consolidation failure, osteophytes precluding a work chamber, excentric talus, severe malunion, bone defect requiring grafting, associated midfoot deformity, etc. The first reports of arthroscopic tibiotalar and subtalar arthrodesis date from the early 1990s. Consolidation rates were comparable to open surgery, but with significantly fewer postoperative complications: infection, skin necrosis, etc. Arthroscopy was for many years reserved to moderate deformity, with frontal or sagittal deviation less than 10°. The recent literature, however, seems to extend indications, the only restriction being the surgeon's experience. Tibiotalar arthrodesis on a posterior arthroscopic approach remains little used. And yet the posterior work chamber is much larger, and initial series showed consolidation rates similar to those of an anterior approach. The surgical technique for posterior tibiotalar arthrodesis was described by Van Dijk et al., initially using a posterior para-Achilles approach. This may be hampered by posterior osteophytes or ankylosis of the subtalar joint line (revision of non-consolidated arthrodesis, sequelae of calcaneal thalamus fracture) and is now used only by foot and ankle specialists. Posterior double tibiotalar-subtalar arthrodesis, described by Devos Bevernage et al., is facilitated by transplantar calcaneo-talo-tibial intramedullary nailing. PMID:26797006

    The orthopaedic surgeons cannot predict the functional results after a distal intra articular radius fracture. The intra-articular incongruity of more than 1 mm is associated with the development of secondary osteoarthrosis. The wrist arthroscopy became an essential help for the reduction of these fractures. The hand is normally in an upright position with a traction of approximately 4-5 kg which facilitates the reduction of the extra-articular fracture component. It is possible to use a technique of horizontal traction. The arthroscopy allows the reduction and control of the fixing of the various fragments, but also the treatment associated lesions associated. One randomized study, which compared 34 arthroscopically treated fractures with 48 openly treated, concluded that the arthroscopy-treated group had better outcome, better reduction, better grip strength and better range of motion than the openly treated group. The treatment of intra articular distal radius fractures with arthroscopic assistance is thus the guaranteeing of the most anatomical reduction of articular surface. It allows the diagnosis and the treatment of the associated lesions, decreases the peripheral fibrous scars of soft tissues by avoiding initially extensive approaches and finally gives better functional results.

  14. Primary Frozen Shoulder Syndrome: Arthroscopic Capsular Release.

    Science.gov (United States)

    Arce, Guillermo

    2015-12-01

    Idiopathic adhesive capsulitis, or primary frozen shoulder syndrome, is a fairly common orthopaedic problem characterized by shoulder pain and loss of motion. In most cases, conservative treatment (6-month physical therapy program and intra-articular steroid injections) improves symptoms and restores shoulder motion. In refractory cases, arthroscopic capsular release is indicated. This surgical procedure carries several advantages over other treatment modalities. First, it provides precise and controlled release of the capsule and ligaments, reducing the risk of traumatic complications observed after forceful shoulder manipulation. Second, release of the capsule and the involved structures with a radiofrequency device delays healing, which prevents adhesion formation. Third, the technique is straightforward, and an oral postoperative steroid program decreases pain and allows for a pleasant early rehabilitation program. Fourth, the procedure is performed with the patient fully awake under an interscalene block, which boosts the patient's confidence and adherence to the physical therapy protocol. In patients with refractory primary frozen shoulder syndrome, arthroscopic capsular release emerges as a suitable option that leads to a faster and long-lasting recovery. PMID:26870652

    The aim of this study was to review all cases of pseudoaneurysm in the literature, in predominantly arthroscopic procedures on the knee, and to report on a case of pseudoaneurysm that we treated. A bibliographic search was conducted for scientific articles published in Brazilian and foreign periodicals over the last 23 years. Forty-seven cases were found, in 40 articles. In addition to these 47 cases, there was the case that we treated, which was also included in the data. Among the operations that progressed with formation of a pseudoaneurysm, 60% were cases of meniscal injuries and 23%, anterior cruciate ligament injuries. In 46% of the cases, the artery affected with the popliteal, and in 21%, the inferomedial genicular artery. The commonest clinical symptom was pain (37%), followed by pulsating tumor (31%), edema of the calf (12%) and hemarthrosis (11%). The median time taken to make the diagnosis was 11 days, but it ranged from one day to 10 weeks after the procedure. Although rare, pseudoaneurysms are a risk that is inherent to arthroscopic surgery. All patients should be made aware of the vascular risks, even in small-scale procedures. PMID:26229905

We accessed the impact of cuff inflations by comparing 24 h BP recorded with a cuff-less tonometric wrist device and an upper-arm oscillometric cuff device. Fifty......-three participants with type 2 diabetes were assigned randomly to four 24-h BP recordings with a cuff (TM2430: visit 1 or 2, and 4) and a tonometric device (BPro: visit 1 or 2, 3, and 4). The mean 24 h systolic BP was significantly higher when measured with the cuff versus the tonometric device (141.6±14.6 vs. 128.......3±14.6 mmHg, P≤0.01), as was nocturnal BP (6.7±5.3 vs. 10.3±7.6%, P=0.002). In conclusion, nocturnal BP decline was higher when measured with the cuff device, suggesting that cuff inflations did not increase night-time BP.

    Posterior shoulder dislocation is an unusual injury often associated with electrical shock or seizure. As with anterior instability, patients frequently present with an impaction injury to the anterior aspect of the humeral head known as a "reverse Hill-Sachs lesion." The treatment of this bony defect is controversial, and multiple surgical procedures to fill the defect in an effort to decrease recurrence have been described. Most of the reports have focused on an open approach using variations of lesser tuberosity and subscapularis transfers, bone allograft, and even arthroplasty to assist with persistent instability. We advocate an arthroscopic technique that involves a suture anchor-based distal tenodesis of the subscapularis tendon or a reverse remplissage procedure. PMID:27073776
