Anatomical Dermal Allograft and Autologous Biceps Long Head Superior Capsule Reconstruction for Irreparable Posterosuperior Rotator Cuff Tears.

ABSTRACT: Superior capsule reconstruction (SCR) can be performed using fascia lata, dermal allograft, and long head of the biceps tendon (LHBT). We present a Technical Note combining dermal allograft and autologous LHBT, reconstructing the superior capsule's actual anatomical thickness and augmenting with single-stranded LHBT. The glenoid side consists of intact LHBT insertion and is covered with dermal allograft. The lateral side comprises posteriorly transpositioned LHBT, dermal allograft, and repairable remnant cuff. First, 1 suture-based anchor is used to fix the biceps 5 to 8 mm posterior to the bicipital groove, and tenotomy is done distal to it, while the glenoid side of the biceps is preserved. Second, 2 suture-based anchors are used to fix the dermal allograft at the glenoid side by 1 double-pulley and 2 mattress sutures. Third, 2 SwiveLock anchors are used to fix allograft's lateral side by 2 reverse mattress sutures. The tension and coverage of the graft can be determined by the position of the SwiveLock anchors. In this way, fewer anchors are needed than the conventional dermal allograft SCR and larger footprint coverage can be achieved than LHBT SCR. A better spacer effect may be achieved by combining both biological grafts' thickness, mimicking the intact shoulder's true anatomy.

Project description:BackgroundTendon transfers of the latissimus dorsi transfer (LDT) or the lower trapezius transfer (LTT) are treatment options for irreparable posterosuperior irreparable rotator cuff tears (PSIRCT). There is still no consensus on which type of tendon transfer is superior in the treatment of PSIRCT. Due to the differences in the anatomy and biomechanics, we hypothesize that there are different clinical situations in which either LDT or LTT should be preferred. The aim of this study was to evaluate the clinical and radiological outcomes of LDT and LTT in patients with PSIRCT to establish a clinical algorithm for the treatment decision.Materials and methodsThis is a retrospective, single-center observational study. Included were patients who underwent arthroscopically assisted LDT (aaLDT) or arthroscopically assisted LTT (aaLTT) for PSIRCT. In all patients, range of motion (ROM), external rotation strength, visual analog scale of pain and subjective shoulder value were determined pre- and postoperatively. Constant-Murley score was evaluated at the final follow-up. The complication rate, failure of the tendon transfer, and revision rate were analyzed.ResultsIn total, 29 aaLDT (age 64 years, median follow-up time 45 months) and 8 aaLTT (age 54 years, median follow-up time 34 months) were included. Active ROM, visual analog scale and subjective shoulder value was significantly improved in both cohorts. At follow-up, the median Constant-Murley score was 73 (aaLDT) and 77 (aaLTT), respectively. The failure rate, including revision surgery, was 14% (aaLDT) and 13% (aaLTT), respectively. Low functional findings preoperatively were correlated to a lower functional outcome at follow-up in both groups. Painful loss of anterior elevation and loss of external rotation had no significant impact on functional outcomes in aaLDT.ConclusionFollowing the treatment algorithm based on the clinical examination, clinical outcome parameters, active ROM and pain could be significantly improved. A good preoperative function was associated with a good clinical outcome in both transfers. A low failure and revision rate supports the good decision-making of the algorithm presented.

Project description:PurposeTo evaluate functional outcomes, return to work, and reoperations associated with lower trapezius tendon transfer (LTT) for irreparable rotator cuff tears.MethodsThis is a retrospective study performed by a single surgeon with minimum 1-year follow-up. LTT was performed using an open (n = 9; 60%) or arthroscopically assisted (n = 6, 40%) technique. Outcomes included failure rate, range of motion, satisfaction, return to work, and pre- and postoperative functional scores, as well as American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation, and the Simple Shoulder Test.ResultsFifteen patients were included. LTT was performed using an open or arthroscopically assisted technique. Mean age was 52 (range 31-62 years), 13 (92.9%) were manual laborers, and 9 (60%) had a worker's compensation claim. Three patients (20%) underwent conversion to reverse shoulder arthroplasty. Of the remaining 12 patients, there were significant improvements in American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, and Simple Shoulder Test at 24.1 ± 9.6 (range 12-38.5) months. Active forward elevation, abduction, and external rotation were all significantly improved. Postoperative satisfaction ratings indicated 67% of the revision-free cohort was "very satisfied" and 33% was "somewhat satisfied" with their outcome. Seven (50%) returned to full duty, 4 (28.6%) returned to modified duty, and 3 (21.4%) were unable to return to work. Two patients (open techniques) underwent a superficial wound debridement for seroma and wound breakdown.ConclusionsLTT results in successful clinical outcomes with a high rate of return to work in a challenging patient population. However, only 67% of patients rated themselves as "very satisfied," and 20% of patients were revised to reverse shoulder arthroplasty before 1 year. Limited preoperative active forward elevation (<90°) appears to predict poor functional results and risk for reoperation.Level of evidenceLevel IV, therapeutic case series.
