Background:. Massive rotator cuff tear can cause functional disability due to instability and degenerative changes of the shoulder joint. In patients with massive irreparable rotator cuff tear, tendon transfer is often used as the salvage procedure. Latissimus dorsi and pectoris major transfer are technically demanding procedures and may incur complications. The biceps tendon transfer may provide a biologically superior tissue patch that improves the biomechanics of the shoulder joint in patients with irreparable rotator cuff tear. This study evaluated the functional outcomes of biceps tendon transfer for irreparable rotator cuff tear in 6 patients with two years and longer follow-up. Methods:. Between September 2006 and October 2011, 50 patients with 50 shoulders underwent surgical repair for MRI confirmed rotator cuff tear. Among them, six patients with massive irreparable rotator cuff tear were identified intraoperatively, and underwent proximal biceps tendon transfer to reconstruct the rotator cuff tear. The biceps tendon was tenodesed at the bicipital groove, and the proximal intra-articular portion of the biceps tendon was transected. The biceps graft was fanned out and the distal end fixed to the cancellous trough around the greater tuberosity with suture anchor. The anterior edge was sutured to the subscapularis and the posterior edge to the infraspinatus tendon or supraspinatus if present. Postoperative managements included sling protection and avoidance of strenuous exercises for 6 weeks, and then progressive rehabilitation until recovery. Results:. The evaluation parameters included VAS pain score, UCLA score, Constant score and AHES score, and X-rays of the shoulder. At follow-up of 25.3 ± 25.0 (range 22 to 63) months, the mean VAS pain score decreased from 9.3 ± 0.8 preoperatively to 1.7 ± 1.4 postoperatively (p < 0.001). All patients presented with significant improvements in pain and function of the shoulder for daily activities after surgery, however, only one patient achieved excellent results. There is no correlation of functional outcome with age, gender and body mass index. There was no infection or neurovascular complication. Discussion:. The biceps transfer provides soft tissue coverage of the humeral head, and restores the superior stability of the shoulder joint. The transferred biceps tendon also improves the mechanics and increases the compression force of the humeral head to the glenoid fossa. The results of the current study showed significant pain relief and improvement of shoulder function after biceps tendon transfer for irreparable rotator cuff tear. Conclusion:. Biceps tendon transfer is effective in the management of massive irreparable rotator cuff tear. The procedure is technically accessible with minimal surgical risks

Rotator cuff tears are common, with failure rates of up to 94% for large and massive tears. 1. For such tears, reattachment of the musculotendinous unit back to bone is problematic, and any possible tendon-bone repair heals through scar tissue rather than the specially adapted native enthesis. We aim to develop and characterise a novel soft-hard tissue connector device, specific to repairing/bridging the tendon-bone injury in significant rotator cuff tears, employing decellularised animal bone partially demineralised at one end for soft tissue continuation. Optimisation samples of 15×10×5mm. 3. , trialled as separate cancellous and cortical bone samples, were cut from porcine femoral condyles and shafts, respectively. Samples underwent 1-week progressive stepwise decellularisation and a partial demineralisation process of half wax embedding and acid bathing. Characterisations were performed histologically for the presence/absence of cellular staining in both peripheral and central tissue areas (n=3 for each cortical/cancellous, test/PBS control and peripheral/central group), and with BioDent reference point indentation (RPI) for pre- and post-processing mechanical properties. Histology revealed absent cellular staining in peripheral and central cancellous samples, whilst reduced in cortical samples compared to controls. Cancellous samples decreased in wet mass after decellularisation by 45.3% (p<0.001). RPI measurements associated with toughness (total indentation depth, indentation depth increase) and elasticity (1st cycle unloading slope) showed no consistent changes after decellularisation. X-rays confirmed half wax embedding provided predictable control of the mineralised-demineralised interface position. Initial optimisation trials show proof-of-concept of a soft-hard hybrid scaffold as an immune compatible xenograft for irreparable rotator cuff tears. Decellularisation did not appreciably affect mechanical properties, and further biological, structural and chemical characterisations are underway to assess validity before in vivo animal trials and potential clinical translation

Massive, irreparable rotator cuff tears occur in about 15% of patients with ruptures of the rotator cuff tendons. There is no consistently agreed management for irreparable rotator cuff tears, however, latissimus dorsi tendon transfer is a recognised technique. We aimed to review the functional outcome of patients undergoing this operation at a single tertiary referral centre. Fourteen latissimus dorsi transfer procedures in thirteen patients from May 2007 to May 2008 were retrospectively reviewed. The mean age of patients undergoing the procedure was fifty nine years. All patients were confirmed to have massive, irreparable (>5cm) rotator cuff tears as determined by MRI or ultrasound. Modified Constant scores (assessing shoulder pain, functional activity and movement) determined pre-operatively and post latissmus dorsi transfer were compared. The mean duration of follow up was 12 months. The mean Modified Constant Score (maximum = 75) improved from 23 points pre-operaively to 52 points post latissimus dorsi transfer (p < 0.05). All patients had improvement in shoulder pain following the operation. There was a trend for younger patients to have greater improvement in functional activity and shoulder movement. From our series, latissimus dorsi transfer is effective at improving functional outcomes in patients with massive, irreparable rotator cuff tears, especially in younger age groups

Rotator cuff tears are the most common cause of shoulder disability, affecting 10% of the population under 60 and 40% of those aged 70 and above. Massive irreparable rotator cuff tears account for 30% of all tears and their management continues to be an orthopaedic challenge. Traditional surgical techniques, that is, tendon transfers are performed to restore shoulder motion, however, they result in varying outcomes of stability and complications. Superior capsular reconstruction (SCR) is a novel technique that has shown promise in restoring shoulder function, albeit in limited studies. To date, there has been no biomechanical comparison between these techniques. This study aims to compare three surgical techniques (SCR, latissimus dorsi tendon transfer and lower trapezius tendon transfer) for irreparable rotator cuff tears with respect to intact cuff control using a clinically relevant biomechanical outcome of rotational motion. Eight fresh-frozen shoulder specimens with intact rotator cuffs were tested. After dissection of subcutaneous tissue and muscles, each specimen was mounted on a custom shoulder testing apparatus and physiologic loads were applied using a pulley setup. Under 2.2 Nm torque loading maximum internal and external rotation was measured at 0 and 60 degrees of glenohumeral abduction. Repeat testing was conducted after the creation of the cuff tear and subsequent to the three repair techniques. Repeated measures analysis with paired t-test comparisons using Sidak correction was performed to compare the rotational range of motion following each repair technique with respect to each specimen's intact control. P-values of 0.05 were considered significant. At 0° abduction, internal rotation increased after the tear (intact: 39.6 ± 13.6° vs. tear: 80.5 ± 47.7°, p=0.019). Internal rotation was higher following SCR (52.7 ± 12.9°, intact - SCR 95% CI: −25.28°,-0.95°, p=0.034), trapezius transfer (74.2 ± 25.3°, intact – trapezius transfer: 95% CI: −71.1°, 1.81°, p=0.064), and latissimus transfer (83.5 ± 52.1°, intact – latissimus transfer: 95% CI: −118.3°, 30.5°, p=0.400) than in intact controls. However, internal rotation post SCR yielded the narrowest estimate range close to intact controls. At 60° abduction, internal rotation increased after the tear (intact: 38.7 ± 14.4° vs. tear: 49.5 ± 13°, p=0.005). Internal rotation post SCR did not differ significantly from intact controls (SCR: 49.3 ± 10.1°, intact – SCR: 95% CI: −28°, 6.91°, p=0.38). Trapezius transfer showed a trend toward significantly higher internal rotation (65.7 ± 21.1°, intact – trapezius transfer: 95% CI: −55.7°, 1.7°, p=0.067), while latissimus transfer yielded widely variable rotation angle (65.7 ± 38°, intact – latissimus transfer: 95% CI: −85.9°, 31.9°, p=0.68). There were no significant differences in external rotation for any technique at 0° or 60° abduction. Preliminary evaluation in this cadaveric biomechanical study provides positive evidence in support of use of SCR as a less morbid surgical option than tendon transfers. The cadaveric nature of this study limits the understanding of the motion to post-operative timepoint and the results herein are relevant for otherwise normal shoulders only. Further clinical evaluation is warranted to understand the long-term outcomes related to shoulder function and stability post SCR

Purpose. Chronic massive rotator cuff tears are challenging to repair completely because of the development of tendon retraction with inelasticity, muscle atrophy and fatty infiltration. The objective of this study was to investigate the clinical outcome and MRI findings after arthroscopic superior capsule reconstruction (ASCR) for symptomatic irreparable rotator cuff tears. Methods. From 2011 to 2013, 12 shoulders in 12 consecutive patients (mean, 70.8 years) with irreparable massive rotator cuff tears underwent ASCR using fascia lata. We used suture anchors to attach the graft medially to the glenoid superior tubercle and laterally to the greater tuberosity as same technique by Mihata et al. We added side-to-side sutures between the graft and infraspinatus tendon and between the graft and residual anterior supraspinatus/subscapularis tendon to improve force coupling. Physical examination, clinical rating system, and magnetic resonance imaging (MRI) were performed before surgery; at 6 and 12 months after surgery; and 6 months thereafter. Average follow-up was 19.1 months (12 to 28 months) after surgery. We assessed patients preoperatively by using the scoring systems of the shoulder index of the American Shoulder and Elbow Surgeons (ASES), the Japanese Orthopaedic Association, and the University of California, Los Angeles. Results. Mean active elevation increased from 59° to 111° significantly and external rotation increased from 28 to 33. The average preoperative scores were 16.0 points by ASES, 48.0 points by JOA, and 10.8 points by UCLA. Average clinical outcome scores all improved significantly after ASCR at the final follow-up (ASES, 73.3 points; JOA, 73.7 points; UCLA, 22.7 points). There was surgical complication as infection. Although infection was controlled by arthroscopic irrigation, the transplanted tendon was absorbed, and preoperative conditions did not functionally improve. Five patients had graft tear during follow-up. Postoperative active range of motion in the healed patients was significantly greater than in the unhealed patients who had graft tears. Conclusions. ASCR restored superior glenohumeral stability and function of the shoulder joint with irreparable rotator cuff tears compared to preoperative function in the cases without postoperative complications. However ratio of graft tears were 50% and clinical results of these cases were not improved sufficiently

The purpose of this study was to evaluate outcome following arthroscopic biceps tenotomy or tenodesis for massive irreparable rotator cuff tears associated with biceps lesions. This is a retrospective study of sixty-eight consecutive patients (mean age 68 ± 6 years) with seventy-two irreparable rotator cuff tears treated with arthroscopic biceps tenotomy (thirty-nine cases) or tenodesis (thirty-three cases). All patients were evaluated clinically and radiographically at a mean follow-up of thirty-five months (range, 24–52). Fifty-three patients (78%) were satisfied. Constant score improved from forty-six to sixty-seven points (p< 0.001). Presence of a healthy, intact teres minor on preoperative imaging correlated with increased postoperative external rotation (40 vs. 18°, p< 0.05) and higher Constant score (p< 0.05). Three patients with a pseudoparalyzed shoulder did not benefit from the procedure and did not regain active elevation above the horizontal level. By contrast, fifteen patients with painful loss of active elevation recovered active elevation. The acromiohumeral distance decreased 1 mm on average, and only one patient developed glenohumeral osteoarthritis. There was no difference between tenotomy and tenodesis (Constant Score sixty-one vs. seventy-three). A “Popeye” sign was clinically apparent in twenty-four tenotomy patients (61%), but none were bothered by it. Two patients required reoperation with a reverse prosthesis. Arthroscopic biceps tenotomy and tenodesis effectively treats severe pain or dysfunction caused by an irreparable rotator cuff tear associated with biceps pathology. Shoulder function is significantly lower if the teres minor is atrophic or fatty infiltrated. Pseudoparalysis or severe cuff arthropathy are contraindications

Introduction: Massive irreparable degenerative rotator cuff tears are amongst the most difficult conditions for treatment in shoulder surgery. These involve usually elderly patients, which present with severely painful and restricted active shoulder movement. These patients have low demand from their shoulders, mainly for pain relief and performing their simple activities of daily living. Major surgery for major tendon transfer will not be advisable in these cases in view of the morbidity involved and the questionable outcome. We suggest a simple non-surgical rehabilitation treatment consisting on anterior deltoid strengthening exercises in the supine position for re-education of the anterior deltoid to compensate for the absent rotator cuff. Methods: 17 patients with degenerative (non traumatic) Massive irreparable rotator cuff tears were recruited. They were all greater than 70 years of age and of mixed gender. Patients were English speaking, had full mental faculties and gave informed consent. They suffered no other shoulder pathology and were not participants in any other upper limb rehabilitation. All patients complained on severe shoulder pain and severely limited active range of motion with inability to actively elevate the arm to the horizontal. They all had full passive range of motion. The diagnosis of a Massive irreparable rotator cuff tear was confirmed by diagnostic ultrasound scan. The shoulder function was evaluated using the Constant Score. Patients’ active shoulder ranges of motion were recorded and video-recorded as well. Each participant was taught the initial 6-week of self Deltoid muscle exercise, executed in supine, at least three times a day. They were instructed that when they felt better control on their active shoulder movements to gradually recline up the head of the bed and continue with the same simple exercise. They were reviewed at 6 weeks re-assessed and re-taught the same exercise, with a 2kg weight in their hand. At the 12th week they were reassessed using the constant score, and their active range of motion was video recorded again. Results: 90% of the participants expressed a significant improvement in their upper limb function already after 6 weeks of treatment. All components of the Constant score (beside the strength) have improved. 90% reported less pain and found general activities of daily living easier to execute and a diminished level of muscle fatigue. 10% of the patients were able to establish a recording of > 1.26kg on the myometer in 90 degrees of abduction. 10% failed to report any benefit. Discussion and Conclusion: Anterior deltoid strengthening exercises in the supine position for re-education of the anterior deltoid seem to have a significant beneficial effect for restoration of shoulder function and pain relief in the majority of patients with Massive irreparable degenerative rotator cuff tears. Using this simple non-invasive rehabilitation technique helps to re-educate the anterior deltoid to compensate for the absent rotator cuff and restore shoulder function

Purpose of the study: Fragile bone and weak soft tissues can create a serious challenge for arthroplasty of the rheumatoid arthritis shoulder. Patients seen late after rotator cuff tears become irreparable may also present a stiff shoulder, further complicating the procedure. Material and methods: The purpose of this study was to assess outcome at more than five years in a prospective series of 12 patients with rheumatoid arthritis of the shoulder with an irreparable rotator cuff tear treated with a hemiarthroplasty with a mobile cup. The radiological and clinical results were compared with those obtained in a control series of ten bipolar humeral prostheses implanted for centered or excentered degenerative disease with irreparable cuff tears. Results: The mean preoperative Constant score was 16.9 points: pain 2.5, activity 4.2, active mobility 9.5, strength 0.7. Active ROM was 63.8° for anterior elevation, 45° for abduction, and 12° for external rotation. At last follow-up, the mean postoperative Constant score was 39.4 points: pain 10.7, activity 10.8, active mobility 13.8, strength 4.1. Mean active anterior elevation was 83.7°, abduction 70.4°, and external rotation 29.1°. Outcome was not significantly different from the control group with degenerative joint disease (p< 0.05). Discussion: The overall Constant score, especially the pain score, was significantly improved (p< 0.05). Improvement in joint motion was modest but comparable with other series in the literature and even better than with conventional hemiarthroplasty for the same indication. There were few complications, mainly superior subluxation favored by the preoperative infra-scapularis or infraspinatus tears. Glenoid wear was significant despite the dual mobility concept. There were no cases of loosening. Conclusion: These results show that hemiarthroplasty with a mobile cut provides acceptable mid-term results for the advanced-stage rheumatoid shoulder with an irreparable rotator cuff tear. Results in this series were comparable with that in the control group of patients with degenerative joint disease. Consequently, the status of the rotator cuff appears to be more important that the inflammatory or degenerative etiology. Certain cuff tears involving the infrascapularis raise the risk of superoanterior instability and could be a limitation for this method. A more constrained prosthesis might be advisable

Introduction. In recently, Reverse shoulder arthroplasty (RSA) in patients with irreparable rotator cuff tear has been worldwidely performed. Many studies on RSA reported a good improvement in flexion of the sholulder, however, no improvement in external rotation (ER)and internal rotation motion (IR). Additionally, RSA has some risks to perform especially in younger patients, because high rates of complications such as deltoid stretching and loosening, infection, neurologic injury, dislocation, acromial fracture, and breakage of the prosthesis after long-term use were reported. Favard et al noted a 72% survival with a Constant-Murley score of <30 at 10 years with a marked break occurring at 8 years. Boileau et al noted caution is required, as such patients are often younger, and informed consent must obviously cover the high complication rate in this group, as well as the unknown longer-term outcome. Its use should be limited to elderly patients, arguably those aged over 70 years, with poor function and severe pain related to cuff deficiency. We developed a novel strategy in 2001, in which we used the humeral head to close the cuff defect and move the center of rotation medially and distally to increase the lever arm of the deltoid muscle. Aim. The aim of this study was to investigate clinical outcome of our strategy for younger patients with an irreparable rotator cuff tear. Materials and Methods. Eighteen shoulders (9 of male patients, 9 of female patients) of patients under 70 years old with an irreparable cuff tears and who were treated with Humeral Head Replacement (HHR) and cuff reconstruction were followed up for more than 12 months. The average age was 63.9 years (range, 58–69 years). The average follow-up period was 27.3 months (range, 12–76 months). The cuff defect was successfully closed in 8 shoulders, whereas 8 shoulders required a Latissimus Dorsi transfer; one other shoulder required a Pectralis Major transfer, and one required both Latissimus dorsi and pectoralis major transfers. Range of motion (flexion, ER), the shoulder score of Japanese Orthopaedic Association (JOA score), and complications were evaluated. Results. Shoulder pain decreased in all patients after surgery. JOA score was improved from 41.1 to 82.6 points after surgery, Flexion motion improved from 72.5 to 145.6 degrees postoperatively and ER increased from 17.5 to 37.8 degrees postoperatively. There were no complications. Conclusion. In our study, HHR using the small head of the humerus and cuff reconstruction for patients under 70 years old with an irreparable rotator cuff tear yielded favorable results as compared to RSA, especially in terms of the ER Furthermore, the advantages of our strategy is able to keep bone stock of the glenoid after surgery. If revision surgery is required, RSA can be performed. Since the patients included in our study were relatively active, long-term follow-up will be required to assess their progress

Introduction. Latissimus dorsi transfer is a procedure used in massive irreparable posterosuperior rotator cuff tears, in young patient with severe pain and significant functional impairment. The purpose of this retrospective study was to evaluate its clinical, radiological and electromyographic results. Methods. Forteen massive irreparable posterosuperior rotator cuff tears were performed with latissimus dorsi transfer between 2000 and 2008, and were reviewed at an average follow-up of 56 months and minimum of 19 months. Five transfers were primary reconstructions, and nine were revision surgeries. Patients’ mean age was 52.7 years. Clinical outcomes were measured by the Constant score, pain level, active range of motion, and strength. Osteoarthritis and acromiohumeral distance were measured on standardized radiographs. Ultrasound examination evaluate the integrity of the tendon. Axial images in CT-scan looked for muscle atrophy of latissimus dorsi in comparison with the controlateral. Electromyographic activity was measured during active flexion, abduction, adduction and rotations. Results. Twelve patients were satisfied. At the last follow-up, the average pain level according to a 100 mm visual analog scale was 31. The mean age and gender-matched Constant and Murley score improved from 34 to 60 % (p=0.003), forward elevation from 89° to 132° (p=0.006), abduction from 92° to 104°, external rotation from 12° to 24° (p=0.015). Mean abduction and external rotation strength were measured at 2.5 kg. Osteoarthritis progressed, and mean acromio-humeral distance has a significant decrease from 7.5 mm to 4.4 mm (p=0.003). Ultrasound examination showed twelve transferred tendons healed to the greater tuberosity. CT-scan showed a small atrophy of the transferred muscle, with a measurement of the cross-sectional area of the muscle belly at the inferior angle of the scapula at 1405 mm2, versus 1644 mm2 for the controlateral (p=0.06). Electromyographic analysis demonstrated a significant higher electric activity on the operative side during abduction and external rotation, and significant lower activity during adduction and internal rotation in comparison with the nonoperative side. Conclusions. Latissimus dorsi transfer allows for significant pain relief and function improvement in irreparable posterosuperior rotator cuff tears at young patients. Its electric activity increase in abduction and external rotation shows that the transferred muscle can integrate a new function and act like an active muscle transfer, in addition to an interposition or tenodesis effect. However we didn't find any depression of the humeral head or strength improvement

Introduction: The suspension bridge principle relies on a firm fixation of the torn rotator cuff at the anterior and posterior margins of the greater tuberosity leaving a mobile section between the two points. In massive rotator cuff tears which cannot be approximated, a partial repair can be performed using the above principle. The aim of this study is to evaluate the functional and radiological results using the above technique with bio-absorbable anchors. Materials and Methods: This is a prospective study of a consecutive series of 59 patients who were found intraoperatively to have a rotator cuff tear of greater than 5cm. There were 41 men and 18 women with an average age of 68 years (range). The average length of follow up was 16 months (12 to 26 months). Patients were assessed objectively with the Constant score, and subjectively with the Oxford questionnaire. Cuff integrity was evaluated using ultrasound. Results: Using the Constant score, the outcome was excellent in 30(51.5%), fair in 24(40.5%) and poor in 5(8.5%). 55(93%) patients had an improvement in pain whilst all had increased movement. 51(86%) had improved activities of daily living, whilst 43(72.3%) had improvement in recreational activities. Ultrasound demonstrated the repair remained firmly anchored in position in 54 patients (91.5%). Five patients showed complete disruption and represented poor functional outcome. Patient satisfaction was 94.9%. Conclusion: Our results confirm that a water tight repair is not necessary for a good functional outcome for massive irreparable tears. The biodegradable anchors have been shown to be holding the repairs well at medium term follow up. In patients with a massive irreparable rotator cuff tear, the suspension bridge principle is a valuable technique

Purpose of the study: The appropriate treatment for massive irreparable rotator cuff tears is a subject of debate. The purpose of this work was to analyze at mean five years follow-up a series of 16 shoulders treated with a latissimus dorsi flap. Material and methods: These 16 patients (seven women) were aged 56 years on average. The procedure was a revision for four shoulders. The tears were all posterosuperior tears and caused invalidating pain in all patients. Mean anterior elevation was 93°. External rotation was 12°. The Constant score, assessed in eleven patients, was 27 points on average. The subacromial space measured 8 mm on average. Supraspinatus fatty degeneration was grade 2 in 45% and grade 3 in 55%. Infraspinatus degeneration was grade 3 in 80% and grade 4 in 20%. The latissimus dorsi flap was associated with a teres major flap in four shoulders and with a deltoid flap in seven. The semi-sitting position was used for 15 of the 16 patients. Discussion: Treatment of massive irreparable rotator cuff tears is a controversial issue. When the subacromial space is preserved, the presence of muscle atrophy and tendon retraction despite forced mobilization it is logical to use several muscle transfers. This small series demonstrated that a significant improvement can be obtained. Nevertheless the postoperative period is long and indications must remain limited. We discuss our results in comparison with other reported series

Purpose of the study: This retrospective analysis was conducted to study the gain provided by a latissimus dorsi flap used as first-intention treatment (group 1) or secondary treatment after prior failure (group 2) for irreparable rotator cuff tears. Material and methods: This series included ten women and nine men, mean age 58 years (range 42-64). The initial tear was a massive (> 5 cm) posterosuperior tear in 16 patients and extended to the upper third of the infra-scapularis in three. Surgery was undertaken because of persistent pain and limited joint motion despite rehabilitation. A subacromial impingement was noted in 15/20 shoulders on the arthroscan and fatty degeneration was noted as grade 3.31 on average for the supraspinatus and 3.1 for the infraspinatus (Goutallier and Bernageau classification). The latissimus dorsi flap was harvested via the superolateral approach and fixed with anchors in the superior border of the infrascapularis and on the trochiter after avivement. Tendon stumps were sutured to the medial part of the aproneurotic sheath of the latissimus dorsi. Results: Overall outcome and outcome in group 1 patients (14 shoulders) and group 2 patients (five shoulders) were noted. Mean follow-up was 19.72 months (range 12–48). The overall Constant score progressed from 33.10 to 54.9 with a mean gain of 53° for elevation (98–151°) and 11° for external rotation (21.5–32.1°). For group 1, the Constant score progressed from 31 (15/51) to 58 (40/75) with a mean gain of 37° elevation (121–155°) and 13° external rotation (22.8–35°). For group 2, the Constant score progressed from 33 to 52 (40/75) with a mean gain of 32° elevation (88–120°) and 6° external rotation (18–24°). Pain improved from 6.3 to 11.8 on the Constant score. Discussion and conclusion: Used as a first intention treatment for massive irreparable cuff tears with fatty degeneration scored greater than grade 3, the latissimus dorsi flap provides better results than when it is used after failure of a prior procedure. Results are good for pain relief and active elevation (45°) but modest for external rotation (6–13°) and zero for force. The two failures and the two cases of only fair subjective outcome were in group 2. We reserve the procedure for painful pseudo-paralytic shoulders in subjects aimed less than 60 years who do not respond to prolonged rehabilitation

Introduction: Post meniscectomy syndrom is an unfavorable disabling outcome for too many patients. This has led to intensive research into finding Methods: for treating irreparable meniscal lesions. The Actifit™ device is a biodegradable, porous, synthetic scaffold for treatment of irreparable partial meniscal tissue loss. When connected to the vascularized zone of the meniscus it promotes blood vessel ingrowth and new tissue generation. Materials and Methods: Patients with irreparable partial meniscus loss into the vascular zone, intact rim, stable knee or joint stabilization within 3 months post surgery, ICRS classification £ 2, and £ 3 previous surgeries on index knee, and no significant malalignment were treated with the device in a non-randomised, single-arm, multi-centre study. Safety was assessed by frequency of serious adverse device effects (SADEs) and implantation-related serious adverse events (SAEs). Efficacy was assessed based on pain (Visual Analogue Scale [VAS] score) and function (Knee and Osteoarthritis Outcome Score [KOOS] and International Knee Documentation Committee [IKDC] score, and Lysholm Knee Scoring scale) at 3, 6 and 12 months post-operatively. Tissue ingrowth was assessed by dynamic contrast enhanced magnetic resonance imaging (DCMRI) at 3 months, and relook arthroscopy with tissue biopsy at 12 months post-implantation. Results: 52 subjects (50 with previous meniscectomies) were enrolled. Mean age was 32.9 ±9.0, 77% were male, all stable knees (3 concomitant ACL repairs) mean defect length was 47.8 ± 10.0 mm. A significant mean improvement in knee pain on VAS and function on IKDC and Lysholm scores as well as differnent categories on KOOS were recorded at all follow-ups post-implantation. Tissue ingrowth into the device was observed on DCMRI in 37/43 (86.0%) subjects at 3 months post-implantation. Gross examination at 12 month relook arthroscopy of 45 subjects to date showed no signs of reactions to the device or its degradation products and biopsy samples from the inner free edge of the scaffold meniscus showed fully vital material, with no signs of inflammation. Similar to native meniscal tissue, three distinct layers were observed based on cellular morphology, the presence or absence of vessel structures, and ECM composition. Conclusion: DCMRI and relook arthroscopy findings illustrate biocompatibility. Tissue ingrowth and biopsy results show potential for differentiation into meniscus-like tissue. Importantly subjects experienced significant pain relief and were able to resume normal activities. No safety concerns have been raised.

Purpose of the study: Old tears of the subscapular muscle situated in the glenoid area are not accessible to direct repair and require locoregional muscle plasty. The clavicular portion of the pectoralis major can be used for reconstruction. The purpose of this study was to describe the operative technique and examine short-term outcome. Material and methods: Five patients, mean age 54 years (45–71 years) with an irreparable tear of the subscapularis in the glenoid area with fatty degeneration greater than grade two in the Goutallier classification were treated. Four had had previous surgery for acromioplasty associated with rotator cuff repair in two or implantation of a humeral prosthesis in one. The preoperative Constant score was 27.5 (mean, range = 8.5–54) due to invalidating pain, limited active mobility and reduced muscle force. Gerber’s lift-off test was positive for those patients for whom it could be performed. Plain x-rays evidenced anterior subdislocation of the humeral head in one case. Subscapular reconstruction was achieved using the entire clavicular portion of the pectoralis major which was dissected and sectioned at its distal insertion on the humerus then reinserted by transosseous suture onto the lesser tuberosity. The rehabilitation program started with active and passive mobility against gravity within a few days of surgery using biofeedback contraction of the muscle flap then active contractions two months postoperatively. Patients were reviewed at a mean 19 months (6–42 months) for clinical and radiological assessment. Results: Four patients had a painless shoulder with a negative lift-off test. The gain in active mobility was predominantly achieved with anterior elevation and abduction. Muscle force was weak leading to a low overall Constant score at revision (mean = 50, range = 30–63). Radiographically, the humeral head was centered exactly as on the preoperative films. There were no cases with a new anterior subdislocation nor an aggravation of a former subdislocation. Functional outcome was better in cases with a unique tear of the subscapularis. Discussion and conclusion: Open surgery is used for primary repair of recent tears of the subscapularis. This technique gives 80 p. 100 good and very good results. In case of symptomatic acromioclavicular osteoarthtisis, better long-term results can be obtained by using a tendodesis of the long biceps and resecting the lateral centimeter of the clavicle. In case of irreparable tears in the glenoid area, reconstruction by transfer of the clavicular portion of the pectoralis major can produce a stable painless shoulder with improved active moblity and normal clinical tests. This method provides anterior stability of the glenohumeral articulation and prevents any anterior subdislocation of the humeral head, thus protecting the joint from secondary degeneration

We wished to assess the usefulness of Inspace balloon arthroplasty (IBA), in our Upper limb unit by regular patient reviews prospectively. This prospective study was started adhering to local approval process. Patients were identified in routine clinical practice by three upper limb consultants presenting with pain and disability and diagnosis of cuff tear was established clinically and on MRI. The patients were explained of ‘available’ treatment options and an information leaflet about balloon arthroplasty provided. Patients were seen in 4 weeks, in a dedicated clinic to find out their willingness to participate. Consultant shoulder surgeons carried out all Balloon arthroplasties and where the cuff was reparable or contraindications identified were excluded from study. All the patients were reviewed by an independent clinician pre-operatively and post operatively using the assessment tools of Oxford Shoulder Scores (OSS), SF12 and VAS at 6 weeks, followed by 3, 6, 12 months and annually after. We performed a total of 32 IBA procedures. At the latest follow-up we identified that 24 patients have completed 2 years post procedure. Of these patients 1 deceased after 6 months, 3 were lost to follow up one each at 6, 12 and 24 months. Three were revised to reverse TSA. The OSS reflects that the positive difference of 10 in the average scores (24 pre-operative versus 34 at 2 years) noted at one year follow up were maintained at 2 years. Similar observations made analysing at 12 months and 2 years scores for the VAS pain scores of 3 at 2 years compared to pre-operative score of 6 and so were improvements in both physical & mental components of SF12. Our study observes that the IBA provides a sustainable pain relief and functional improvements over 2 years and may be a suitable alternative in physiologically compromised patients with irreparable RCT

We present a retrospective analysis of 50 cases of cuff tear arthropathy, treated over a seven year period by use of reverse geometry shoulder prosthesis. 98% follow-up was achieved with average follow up of 3 years. Mean (SD) age was 81.3 (9.2) years and female to male ratio was 5:1. Six patients had bilateral reverse geometry shoulder replacements. Patients were assessed with pre-operative American Shoulder and Elbow Score (pre-op ASES) and post-operative American Shoulder and Elbow Scores (post-op ASES), Oxford, Constant and SF36 scores. Mean pre-op ASES was 22.29 (95%CI: 9.1 – 37.9) and post-op ASES score was 65.2 (95%CI: 48.5 – 81.9), (P< 0.001, Paired t-test). Mean post operative Oxford score was 27.25 (95% CI: 18.4 – 27.6). Mean post operative Constant score was 63.2 (95% CI: 52.6 – 79.6). X-ray review was performed to assess scapular notching and Sirveaux score was used to grade extent of notching. 11 patients had Sirveaux grade 0, 5 had grade 1, 6 had grade 2, 12 had grade 3 and 8 had grade 4 notching. Intra-operative complications included 2 glenoid fractures. Post-operative complications included 2 acromion fractures and 2 episodes of subsidence with dislocation. None of the patients developed post operative haematoma. There was one episode of infection in one patient that required further surgery. Iteration of approach with increasing experience over the years will be discussed. Ours is the biggest series of reverse geometry prosthesis used for irreparable rotator cuff tear arthropathy published so far in the literature and our results have shown superior results in terms of improvement in function and complications. We recommend reverse geometry shoulder replacement is the way forward to treat irreparable cuff tear arthropathy of shoulder

The goal of this retrospective study was to evaluate the result of this technique proposed as initial treatment (group 1: 17 cases) or after a failure of repairing cuff (group 2: 7 cases). Materials and Methods: Eleven females and thirteen males with an average age of fifty six years were available for this study. Initial rupture was always massive (2 tendons, retracted to the glenoid level), superior and posterior(20 cases) with superior lesion of the subscapularis in 4 cases. An ascension of the humeral head was found in 18 cases. Degree of fatty degeneration evaluated with CT arthrogram was 3.45 for the supra spinatus and 3.25 for the infra spinatus. The latissimus dorsi was harvested with axillary approach and released from the angle of the scapula to be able to cover the humeral head. Coraco acromial arch was preserved. Abduction splint was maintained 6 weeks. Results: The average follow up was 21 months(12/48). For the 24 patients Constant score was improved from 34,6 to 55,6(+21): a significant improvement of forward active elevation from 98° to 153 (+55°) but a little improvement of external rotation from 23 to 33 (+10°). The best results were obtained in group 1: constant score progressed from 34 to 58 (+24) with an increasing of 66° (98 to 164°) of forward active elevation and 13°(22 to 35°) of external rotation. Results of group 2 are less: Constant score progressed from 36 to 51(+15), forward elvevation 33°(96 to 129°) and 3° (27 to 30°) of active external rotation. 2 failures caused by a rupture of the transfer. Painrelief was obtained in 90% but any improvement of strength. Discussion and Conclusion: Ours results indicate that latissimus dorsi transfer improves range of motion, pain, function and patient satisfaction with irreparable rotator cuff tear. We recommend to use it for pseudoparalytic and painfull shoulder, with a persistent acriomo humeral space, after failure of rehabilatation, for young patient. A stable humeral head with a good subscapularis without previous operation are good pronostic factors

Various arthroscopic techniques using differing graft materials have been described and present a potential alternative to arthroplasty for rotator cuff arthropathy. We describe the short-term outcomes of allograft reconstruction, having evolved of our surgical technique from graft interposition to superior capsule reconstruction (SCR). All patients with an irreparable tear, in the absence of clinical and radiograph evidence of osteoarthritis, who underwent an allograft (Graft Jacket. TM. ) reconstruction with either an arthroscopic interposition or SCR technique within our institution were included. A retrospective case note analysis was performed to ascertain perioperative details including total operating and consumable implant costs. 15 patients were in the interposition group, mean age 66 years (48–77). Mean postoperative follow-up time was 17 months (1.9 −27.8). The mean OSS improved from 30.6 to 35.7 (p<0.05). Additionally, mean pain scores out of 10 improved from 7.7 to 1.5 (p<0.01). Mean satisfaction for the surgery was 7.8 out of 10. Complications included 2 re-ruptures (13.3%), 1 infection (6.7%) and 1 case of no improvement (6.7%). In the SCR group, there were 10 patients, mean age 64.5 (56– 68 years). Half of these patients had previous rotator cuff surgery. Mean postoperative follow-up time was 8.7 months (1.9 – 16.3). The mean OSS improved from 24 to 32.9 (p<0.01). Similarly, pain scores decreased from 7.9 to 3.5 (p<0.01). Mean satisfaction was 7.2. Complications included 1 case of no improvement (10%) resulting in a reverse TSR and 1 re-rupture (10%). A formal, prospective comparison trial is advocated to determine if SCR is superior

Massive irreparable rotator cuff tears (MIRCTs) represent a difficult situation especially in painful and pseudoparalytic patients. A new technique, consisting of an arthroscopic implantation of an inflatable biodegradable “balloon”, serving as a temporary subacromial spacer, has been introduced recently for MIRCTs. The purpose of this paper is: 1) to present the efficacy and safety results of patients treated with the balloon; 2) to show that these results are maintained over time, after balloon degradation; 3) to compare these results to published results of other procedures available for MIRCTs. This paper presents the first group of 22 patients (females/males 13/8, one bilateral), treated in a single-surgeon, prospective and on-going series of 97 shoulders operated with the balloon, since September 2010. The mean age is 69.3 (52–86) and the average follow-up 52.5 months. The balloon is inserted arthroscopically and inflated with saline. The procedure is simple with a short operative time (10–20 min). It can also supplement partial repairs, especially of the subscapularis, as well as repairable massive tears with bad tissue quality. The balloon is not used in severe cuff tear arthropathy or complete insufficiency of the external rotators. Final outcome scores, Constant (CS) and UCLA scores are obtained at least three years after complete balloon degradation (which occurs within 12 months), and are also compared to those of other treatments available for MIRCTs. No device related safety issues were observed in this group. Good results, including rapid pain relief and restoration of active motion, which maintained over time, are obtained in 85% of the patients. The CS has improved significantly (average preop/postop: pain 2.9/12.7; ADL 6.8/17.4; ROM 22.8/36.6; strength 3.1/5.6; TOTAL 35.8/72.3; NORMATIVE 42.7/86.4). The UCLA score has also improved significantly (preop/postop: pain 1.9/8.6; function 3.9/8.6; active flexion 3.5/4.5; strength in flexion 2.4/3.4; satisfaction 0/4.5; TOTAL 11.2/29.8). Pseudoparalysis is reversed (average preop/postop flexion 86°/156.8°). The CS and UCLA score for the balloon are superior compared to published results of debridement, biceps tenotomy/tenodesis, partial repair, tuberoplasty and latissimus dorsi transfer. CS (86.4/63.8), CS pain (12.7/11.9) and flexion (156.8/128.0) are also better for the balloon compared to the reverse prosthesis. The balloon is indicated for MIRCTs, as well as reparable massive tears with a high risk of retear. The implantation is a straightforward and short procedure, which has excellent safety profile and positive effect on painful MIRCTs including pseudoparalysis. The balloon provides significant improvement in the CS and UCLA score that persists way beyond its degradation. The balloon patients' shoulder function is superior to the other available treatment options. Additional studies are needed to further confirm the effectiveness of the balloon as a first line treatment for MIRCTs
