Return-to-activity after anatomical reconstruction of acute high-grade acromioclavicular separation.

BACKGROUND: To evaluate return-to-activity (RtA) after anatomical reconstruction of acute high-grade acromioclavicular joint (ACJ) separation. METHODS: A total of 42 patients with anatomical reconstruction of acute high-grade ACJ-separation (Rockwood Type V) were surveyed to determine RtA at a mean 31 months follow-up (f-u). Sports disciplines, intensity, level of competition, participation in overhead and/or contact sports, as well as activity scales (DASH-Sport-Module, Tegner Activity Scale) were evaluated. Functional outcome evaluation included Constant score and QuickDASH. RESULTS: All patients (42/42) participated in sporting activities at f-u. Neither participation in overhead/contact sports, nor level of activity declined significantly (n.s.). 62 % (n = 26) of patients reported subjective sports specific ACJ integrity to be at least the same as prior to the trauma. Sporting intensity (hours/week: 7.3 h to 5.4 h, p = .004) and level of competition (p = .02) were reduced. If activity changed, in 50 % other reasons but clinical symptoms/impairment were named for modified behavior. QuickDASH (mean 6, range 0-54, SD 11) and DASH-Sport-Module (mean 6, range 0-56, SD 13) revealed only minor disabilities at f-u. Over time Constant score improved significant to an excellent score (mean 94, range 86-100, SD 4; p < .001). Functional outcome was not correlated with RtA (n.s.). CONCLUSION: All patients participated in sporting activities after anatomical reconstruction of high-grade (Rockwood Type V) ACJ-separation. With a high functional outcome there was no significant change in activity level (Tegner) and participation in overhead and/or contact sports observed. There was no correlation between functional outcome and RtA. Limiting, there were alterations in time spent for sporting activities and level of competition observed. But in 50 % those were not related to ACJ symptoms/impairment. Unrelated to successful re-established integrity and function of the ACJ it should be considered that patients decided not return-to-activity but are very content with the procedure.

[Latissimus dorsi transfer for the treatment of irreparable rotator tears: indication, surgical technique, and modifications]. / Latissimus-dorsi-Transfer bei nichtrekonstruierbarem Rotatorenmanschettendefekt : Indikation, Operationstechnik und Technikmodifikationen.

OBJECTIVE: Improvement of glenohumeral dynamic centering and active external rotation by a transfer of the latissimus dorsi tendon to the greater tuberosity or the lateral proximal humerus. INDICATIONS: Irreparable posterosuperior rotator cuff tears. CONTRAINDICATIONS: Cuff tear arthropathy, subscapularis tendon tear, deltoid insufficiency, palsy of the axillary nerve. SURGICAL TECHNIQUE: Diagnostic arthroscopy in lateral decubitus position. Placement of suture through the biceps tendon and supragleonidal tenotomy. Posterior approach. Preparation and mobilization of a pedicled latissimus dorsi flap. Second anterior incision with delta split. Debridement of the torn rotator cuff. Insertion of suture anchors in the greater tuberosity. Passing of the muscle flap inferior to the posterior deltoid and fixation with suture anchors to the greater tuberosity (where applicable suturing with remaining rotator cuff tissue). POSTOPERATIVE MANAGEMENT: Immobilization in a thorax abduction cast for 6 weeks. Passive exercises out of the cast (IR/ER 0-0-free and ABD/ADD free-45-0°). Active assistive exercises from week 4 postoperatively. Stepwise increase of passive range of motion from week 7. Unlimited active range of motion from week 10. RESULTS: After an average follow-up of 57.6 (SD 27.5) months 17 patients were examined clinically. The average age at time of surgery was 55.6 (SD 7.7) years. At follow-up the patients showed an average Constant score of 64.4 points (SD 17.4). The active external rotation in 0° abduction was 16° (SD 17). The 4 patients (23%) with a sonographically-detected retear of the latissimus flap presented worse clinical results.
