PURPOSE

We performed an anatomical study to clarify humeral insertions of coracohumeral ligament (CHL) and superior glenohumeral ligament (SGHL) and their relationship with subscapularis tendon. The purpose of our study was to explain the « Comma Sign » observed in retracted subscapularis tears treated by arthroscopy.

MATERIAL AND METHODS

20 fresh cadaveric shoulders were dissected by wide delto-pectoral approach. After removal the deltoid and posterior rotator cuff, we removed humeral head on anatomical neck. So we obtained an articular view comparable to arthroscopical posterior portal view. We looked for a structure inserted on subscapularis tendon behind SGHL. By intra-articular view we removed SGHL and CHL from the medial edge of the bicipital groove, then subscapularis tendon from lesser tuberosity. We splitted the rotators interval above the superior edge of subscapularis tendon and observed the connections between subscapularis tendon, CHL and SGHL.

Purpose of the study: Many rotator cuff tears occur in the context of a work accident or an occupational disease (schedule 57-A in the French occupational disease nomenclature). This context is a negative factor for outcome although diverse opinions are expressed in the literature. We wanted to study the occupational outcome of operated patients after rotator cuff repairs and to determine what factors affect this outcome.

Material and method: From 2000 to 2005, 1155 patients underwent rotator cuff repair performed by the same operator. The context was an occupational context (schedule 57-A) in one quarter of these patients (n=290, 25.1%). Among these, 87.6% (n=254) responded to a mail questionnaire. In all 262 shoulders were included in this series (8 bilateral cases). Male gender predominated (72%) and 69% of the tears were in the right shoulder. Mean patient age was 50.53±6.4 years. In this series, 67% of the tears were related to a work accident and 33% to an occupational disease. The patients were salaried workers (75.2%), independent craftsmen (12.6%), and civil servants (11.8%). The occupational category was heavy manual labour (68.3%), light manual labour (25.5%), non manual occupation (6.1%). The injury involved one tendon in 64.1%, two tendons in 28.2% and three tendons in 7.6%. Classical open repair was performed for 70.6%), mini-open repair for 9.2%, and arthroscopic repair for 20.2%.

Results: Patients resumed their occupational activity in 59.64% of the cases (mean age 48±0.8 years); 40.45% did not resume their occupational activity (mean age 54±5.3 years). Excepting cases of retirement or interruption related to another medical condition, the shoulder was the reason for not resuming work in 16% of patients. Young age (p=0.0005) and type of surgery (open procedure p=0.0004) were factors favouring resumption of occupational activity while gender, occupational category and type of injury had no effect. The duration of sick leave (full time) depended on the occupational category (p=0.004) and somewhat on gender, age, occupational situation, work accident or occupational disease, and type of surgery/

Conclusion: Work accidents or occupational disease were not synonymous with failure of rotator cuff repair. Age was the leading prognostic factor.

Purpose of the study: Four elements differentiate myotendinous tears of the infraspinatus from other rotator cuff tears: the tendon insertion on the trochiter and the joint capsule are spared; the onset in characterized by intense muscle oedema followed at 6 to 12 months by severe and definitive fatty degeneration.

Material and method: Fifty-nine myotendinous tears of the infraspinatus were collected prospectively from 1993 to 2007. Female gender predominated (58%); trauma was noted at onset in 22% of the shoulders and the mean age of discovery was 48.9 years. Twenty-nine shoulders were seen at the acute phase with significant muscle oedema recognized on the MRI T2 Fat Sat sequence. A second group of 30 patients had grade 4 fatty infiltration of the infraspinatus without full thickness cuff tears. The EMG was available for 23 shoulders and was normal in all, ruling out a neurological cause. Associated lesions of the supraspinatus and infraspinatus tendons were: tendon calcification (61%) and partial tears at the acute phase (21%) and chronic phase (70%) suggesting a degenerative cause.

Results: Twenty-four patients underwent surgery and 35 had a medical treatment. At mean 46 months follow-up (range 12–125) the Constant score improved from 51.7 to 69.4 points (p< 0.0001). There was no different statistically between the operated and non-operated patients (p=0.325). All patients seen at the acute phase of the oedema progressed to complete grade 4 fatty degeneration of the muscle, irrespective of the treatment delivered.

Discussion: Early diagnosis of this lesion can be achieved with T2 Fat Sat MRI sequences. Arthroscopic repair to tighten the infraspinatus muscle could avoid the irremediable degeneration with total loss of muscle function.

Purpose: Reverse shoulder arthroplasty (RSA) is becoming increasingly common for a variety of indications. The most common postoperative complication is instability. The objectives of this study are to describe causes of RSA instability and preventive and treatment recommendations.

Method: All members of the American Shoulder and Elbow Society were asked for cases of RSA instability. We retrospectively reviewed 52 cases in 52 patients, performed by 13 surgeons. The mean age was 67.5 years (range, 36–83). The mean follow-up was 32.7 months (range, 3–43).

Results: The etiology included: cuff tear arthropathy (14 patients); revision arthroplasty (13 patients); fracture sequelae (6 patients); and other (6 patients). Twenty-four patients had previous shoulder surgery. All patients had a deltopectoral approach. Anterior deltoid deficiency was noted in 3 cases. Subscapularis insufficiency was noted in 27 cases. Humeral component dissociation occurred in 2 patients. The instability was: anterior (27 patients); posterior (5 patients); or inferior (3 patients). Instability occurred: in the first 48 hours (10 cases); between 2 to 30 days (13 cases); or after one month (12 cases). Causes of instability included: inadequate soft-tissue tension (23 patients); a large antero-inferior release (22 patients); subscapularis insufficiency (7 patients); hematoma (2 patients); trauma (2 patients), deltoid insufficiency (2 patients); glenosphere malposition (2 patients); acromion fracture (2 patients); and other (4 patients). Initial treatment included: non-operative (6 patients); closed reduction (23 patients); open reduction (3 patients); and revision arthroplasty (11 patients). Final outcomes included: persistent instability (7 patients); humeral revision (19 patients); glenoid revision (one patient); hemiarthroplasty (3 patients); and resection arthroplasty (2 patients).

Conclusion: Main causes of RSA instability include inadequate soft tissue tension, large anteroinferior release and subscapularis insufficiency. Preventive measures include careful patient selection, restoration of humeral length, minimizing anteroinferior releases, maximizing soft-tissue tension, maintaining or restoring subscapularis integrity, immobilization in the case of subscapularis insufficiency and use of a postoperative drain. Treatment recommendations include restoration of humeral length, soft-tissue retensioning and prolonged immobilization.

Purpose of the study: Latissimus dorsi transfer is proposed for irreparable superior and posterior rotator cuff tears, particularly in the effect of deficient active external rotation. The purpose of this study was to analyzed outcome at minimum two years follow-up.

Material and methods: Between 2001 and 2002, eleven patients underwent latissimus dorsi transfer for an irreparable tear of the supraspinatus and infraspinatus. Surgery was proposed because of the patient’s young age and occupational activity level, or because of a disabling deficit of active external rotation. There were six men and five women, mean age 52.5 years (range 36–66 years). There were seven right shoulders and nine dominant shoulders. Symptom onset was progressive in seven with a mean duration of 33 months (range 2–144 months). Active external rotation was measured at −14° to 29° in five patients with a positive dropping test. Three patients presented pseudoparalysis. The preoperative Constant score was 52±12 points. Preoperative the subacromial space measured less than 6 mm in all patients. Muscle degeneration of the infraspinatus was noted grade 2 or greater (Goutallier).

Results: Mean follow-up was 26 months (range 24–36). Subjective outcome was very satisfactory for eight patients, satisfactory for one and disappointing for two. Seven of nine patients resumed their occupational activity. The postoperative Constant score was 73±10 points. None of the patients presented pseudoparalysis at review. Pain was improved in all. Active external rotation was significantly improved in six. Postoperative, the dropping test persisted in two patients. The subacromial space was still 6 mm. Better results were obtained when active deficit was predominant than when anterior elevation (pseudoparalytic shoulder) or external rotation (positive dropping test) were predominant.

Discussion and conclusion: Latissimus dorsi transfer provides a solution for irreparable superior and posterior rotator cuff tears. The pain relief is significant. Active external rotation is improved. This is an interesting alternative in young patients or when the motor deficit is a severe handicap.

Purpose of the study: Revision shoulder arthroplasty is generally considered to be a difficult procedure yielding modest improvement.

Material and methods: We report a prospective study of 45 patients, aged 69.8 years (range 49–85 years). Thirty-two patients had a simple humeral prosthesis and thirteen a total prosthesis. A reversed prosthesis was used for all revisions. The reasons for the revisions were classified into five groups: failure of prosthesis implanted for fracture (36%), glenoid problems of a total shoulder arthroplasty (24%), prosthetic instability (18%), failure of a hemiarthroplasty implanted for rotator cuff tear (11%), failure of a hemiarhtroplasty implanted for post-traumatic osteoarthritis (11%). The revision consisted in replacement with a reversed prosthesis. Patients were assessed pre and postoperatively using the Constant score for the clinical assessment and plain x-rays for the radiological assessment.

Results: Forty-one patients were reviewed at mean follow-up of 42.1 months (range 24–92). The four other patients died during the first two postoperative years. Subjectively, 73% of patients were satisfied. The Constant score improved from 187.7 to 55.6 on average. The best gain was obtained for the pain and daily activities scores.

Discussion: Revision shoulder arthroplasty provides only moderate improvement. Neer called a limited goal surgery. Results published on revision shoulder arthroplasty using a non-constrained prosthesis show that the functional gain is moderate. Revisio with a reversed total prosthesis gives better results because of the lesser impact of the cuff deficiency. The rate of complications after revision is greater than with first intention implantations.

Conclusion: Use of a reversed total shoulder prosthesis for revision shoulder arthroplasty provides encouraging results in terms of the mid-term functional outcome.

Purpose of the study: When repairing rotator cuff tears, injury to the infraspinatus is generally a posterior extension of a supraspinatus tear. The description of isolated tears of the infraspinatus has not been to our knowledge reported in the literature. We report a series of 13 cases with more than one year follow-up.

Material and methods: Thirteen patients underwent surgery for an isolated tear of the infraspinatus between 1995 and 2004. There were ten men and three women. Mean age at surgery was 47 years (range 34–62). The right shoulder was involved in seven of the thirteen cases, and the dominant shoulder in eight. A progressive onset was observed in eleven patients and nine had a history of treated calcified tendinopathy. Clinically, pain was the predominant symptom. The Jobe test was deficient in all patients as was external rotation (except one patient). The preoperative Constant score was 70 (range 62–87). X-rays revealed type C posterior calcification in nine patients. A full-thickness tear was observed in seven cases, a partial deep tear in three, and a partial superficial tear in three. Isolated fatty degeneration of the infraspinatus noted Goutallier grade 2 or greater was observed in seven patients. Open surgical repair was preformed in all patients.

Results: Mean time to revision was 29 months (range 12–82). Subjectively, six patients were very satisfied, six were satisfied, and one was disappointed (failure by secondary tear). Two shoulder-hand syndromes were noted in the postoperative period. At last follow-up, the Constant score was 83.5 (range 64–97). All patients except one were satisfied with pain relief but the lack of force was significant.

Discussion and conclusion: Isolated tears of the infra-spinatus are rare, but there is a notable relationship with calcifying tendinopathy of the same tendon. Repair should be undertaken before the development of fatty degeneration in order to improve the chances of force recovery.

Purpose: Appropriate treatment of full-thickness tears of the rotator cuff with subacromial impingement remains a subject of debate. Considering that in most patients, spontaneous tears of the long biceps tendon reduces the pain and that subacromial osteoarthritis is well tolerated by many patients, we proposed arthroscopic tenotomy of the long biceps in this indication with the aim of relieving pain. We report here the long-term outcome.

Material and methods: Between 1988 and 1999, 307 arthroscopic tenotomies of the long biceps tendon were performed in patients with unrepairable tears of the rotator cuff tendons (massive full thickness tears, old patients, non-motivated patients). The procedure was isolated in 64% and associated with acromioplasty in 36%. All patients were given prior medical treatment. Mean age at surgery was 64.3 years. The preoperative subacromial height was 6.6 mm. The tendon lesion was an isolated tear of the supraspinatus in 31%, tears of two tendons in 44.6% and tears of three tendons in 21.8%, and isolated tears of the subscapularis in 2.6%. Mean follow-up was 57 months (24–168).

Results: The Constant score improved from 48.4 to 67.6 points (p< 0.001). Glenohumeral osteoarthritis (Samilson) increased from 38% to 67% of the shoulders postoperatively. Association with acromioplasty improved the objective and subjective result solely in the group of isolated tears of the supraspinatus. The size of the tear and the degree of fatty degeneration of the rotator cuff muscles had a statistically significant influence on functional and radiographic outcome (p< 0.001) while time since surgery had no effect on radiographic outcome (p< 0.001).

Discussion: This simple easy-to-perform procedure yielded pain relief at rest and also nighttime pain. It can be recommended for massive rotator cuff tears with sub-acromial impingement in elderly or poorly-motivated patients whose pain fails to respond to medical treatment. This procedure does not allow recovery of shoulder motion or force.

Purpose: The purpose of this study was to analyse outcome of shoulder prostheses after radiotherapy, to define a specific clinicoradiological entity, and evaluate incidence of complications.

Material and methods: Fourteen shoulder prostheses were implanted in 13 women who had been treated for breast cancer with complementary radiotherapy and one man treated for Hodgkin’s lymphoma. The time from radiothearpy to implantation was 16 years, seven months. Two forms were identified on the preoperative x-rays: seven cases with typical avascular osteonecrosis according to the Arlet and Ficat classification, and seven cases with a radiographic presentation of arthritis or degenerative disease. Humeral prostheses were used in five cases and a total shoulder arthroplasty in nine.

Results: Four implants had to be removed, three for sepsis, and five patients required revision surgery. The mean postoperative Constant score for the ten prostheses still in place was 53.1 points with a mean elevation of 111° at three years seven months follow-up. The gain in pain score was 8.5 points with a mean result of 10.9 points. The results were different depending on the initial radiological form, with less favourable outcome observed in typical osteonecrosis.

Discussion: This study demonstrated a particular radio-clinical entity independent of classical osteonecrosis of the humeral head. The surgical procedure was more difficult and the outcome was less satisfactory than in the classical forms with a high rate of complications.

Purpose: The purpose of this study was to analyse the factors affecting outcome after prosthesis implantation for osteonecrosis of the humerus in order to ascertain details concerning the indications for humerus or total prostheses in this condition.

Material and methods: Forty-seven women and 27 men, mean age 57 years with osteonecrosis of the humerus underwent surgery for implantation of 80 shoulder prostheses. According to the Arlet and Ficat classification as modified by Cruess there were five grade II, fifteen grade III, 41 grade IV and fourteen grade V shoulders, with five unclassifiable shoulders. there were 14 supraspinatus tears and five infraspinatus tears. The 26 total shoulder prostheses and 54 humeral prostheses were reviewed at a mean 47 months follow-up. Pre-operative x-rays were available for 65 shoulders and postoperative x-rays for 58.

Results: The subjective outcome was considered good irrespective of the grade (very satisfied 60%, satisfied 30%, dissatisfied 4%). The mean postoperative Constant score was 70 ± 15. The preoperative score was lower for more advanced disease but the difference was not significant at postoperative assessment. The total prosthesis provided better results in grade V shoulders and the hemiprosthesis in grade II and III shoulders.

The result of the humeral prostheses depended on the grade of necrosis. The postoperative Constant score was lower for advanced necrosis with lower scores for motion, force and pain (which was not influenced by age). At last follow-up, 31% of the x-rays revealed a significant narrowing of the glenoid-head space. The clinical outcome was significantly less satisfactory for all Constant scores. Rotator cuff tears, preoperative stiffness favoured glenoid wear. Tears of both cuff tendons led to poor outcome. Bone collapse with impaction of the head into the glenoid and medialisation of the humerus was a significant factor predictive of less satisfactory outcome.

Discussion: The grade of necrosis is a determining factor for indications for humerus or total shoulder arthroplasty for the treatment of osteonecrosis. Our objective results lead us to recommend a humeral prosthesis for grade II and III patients and a total shoulder arthroplasty for grade V patients. For grade IV patients, the choice depends on patient age, shoulder stiffness, the status of the cuff, and most importantly, collapsus of the head of the humerus with impaction-medialisation of the humerus.
