Purpose: To evaluate the clinical and radiographic outcome of a biodegradable subacromial spacer in the treatment of massive irreparable rotator cuff tear.
Methods: Between January 2011 and December 2014, all shoulders with symptomatic massive irreparable rotator cuff tears treated at our institution with arthroscopic implantation of a biodegradable subacromial spacer followed for at least 1 year were included in our series. Patients with osteoarthritis ≥ grade 3 in the Hamada classification were excluded. Outcome measures included pre- and postoperative, range of motion, Constant score, acromiohumeral distance, and Hamada classification on anteroposterior and lateral radiographs.
Results: Thirty-nine consecutive shoulders (37 patients) met the inclusion criteria. The mean age of patients was 69.8 (53-84) years. At the last follow-up (mean 32.8 ± 12.4 months), range of motion was significantly increased for all patients in anterior elevation (from 130° to 160°, P = .02), abduction (from 100° to 160°, P = .01), and external rotation (from 30° to 45°, P = .0001). The mean Constant score was also significantly (P < .001) improved from 44.8 (±15.2) preoperatively to 76.0 (±17.1) at the last follow-up. The mean acromiohumeral distance significantly (P = .002) decreased from 8.2 mm (±3.4) to 6.2 mm (±3.1) at the last follow-up. The Hamada score progressed of 1 radiographic stage in 4 shoulders (15%) and progressed of 3 stages in 2 (4%), whereas the other 32 shoulders remained stable. No intra- or postoperative complications were found except for 1 patient who required a revision for spacer migration.
Conclusions: Arthroscopic implantation of a subacromial spacer for irreparable rotator cuff tear leads to significant improvement in shoulder function at a minimum of 1 year postoperatively.
Level Of Evidence: Level IV, therapeutic case series; treatment study.

Purpose: To explore if recentering the humeral head could improve shoulder abduction in shoulders with irreparable massive rotator cuff tears (IMRCTs).
Methods: Nine fresh-frozen cadaveric shoulders were used to simulate the intact condition and IMRCTs as controls. Four 'recenter' interventions were then sequentially applied: subacromial interposition (SI) using 4- and 8-mm spacers and superior capsule reconstruction (SCR) using two- and four-layer fascia lata grafts.
Massive rotator cuff tears are a challenge for patients and surgeons. We explored the outcomes of patients with massive rotator cuff tears primarily treated with primary cuff repair augmented with a subacromial balloon spacer. The mean age of the patients was 64.

Background: Subacromial balloon spacer implantation (SBSI) attempts to decrease glenohumeral joint (GHJ) pain and improve function in patients with an irreparable rotator cuff tear (RCT) and minimal osteoarthritis. Between 12 and 26 weeks post-SBSI, gradual implant resorption may create a "balloon dip" that decreases GHJ function and increases pain. This retrospective cohort study attempted to delineate shoulder function, active mobility, strength, pain, and functional task impairment during the "balloon dip" period.

Recent attention has turned toward the prevention of acromiohumeral abutment in the treatment of irreparable rotator cuff tears (IRCTs). This can be achieved through tendon transfer with a bridging allograft, superior capsular reconstruction, dermal allograft application to the greater tuberosity (biologic tuberoplasty), bursal acromial reconstruction, or subacromial balloon spacer placement. Recent literature has demonstrated increased graft thickness is associated with improved clinical outcomes after superior capsular reconstruction, suggesting a potential role of a direct bone-to-bone contact between the greater tuberosity and acromion in symptom generation in patients with IRCTs.
