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 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.
