The use of a subacromial spacer-inspace balloon in managing patients with irreparable rotator cuff tears.

ABSTRACT:

Aim

The objective of this prospective non-randomized study was to establish the role of biodegradable sub-acromial spacer (InSpace™) insertion in the management of patients with massive irreparable rotator cuff tear by reporting beneficial effects on the pain relief and functional outcomes in these patients.

Methods

This is a prospective non-randomized study of patients treated for irreparable cuff tears during a period between January 2014 and November 2016.14 patients with symptomatic massive irreparable rotator cuff tears were managed with arthroscopic debridement and implantation of a biodegradable subacromial spacer and were followed up for at least one year (8-16?m). Inclusion criteria were patients with irreparable rotator cuff tears that failed the conservative management, with muscle retraction (Patte?>?stage 2), muscle atrophy, and fatty infiltration (Goutalier type 3). Patients with osteoarthritis grade 3 in the Hamada classification and/or without preserved passive motion were excluded from our study. Outcome measures included pre and postoperative, the range of motion, Constant and Oxford shoulder scores. The decision to perform surgery was made after failure of nonoperative treatment and rehabilitation (massive rotator cuff tear protocol, reading shoulder unit)for at least six months.

Results

Fourteen shoulders (14 patients, ten male four female) met the inclusion criteria. The mean age of patients was 76.2 (70-85) years. During the last follow-up (8-16 months mean 12.6 months), the range of motion was significantly increased in all patients with anterior elevation (from 80 to 105°), abduction (from 70 to 110°), and external rotation (from 25 to 35°). The mean Constant score was also significantly (P?ConclusionsArthroscopic implantation of a subacromial spacer for irreparable rotator cuff tear resulted in a noticeable improvement in pain relief and shoulder function at a mean 12.6 months follow up. It is a quick, safe and a minimally invasive procedure that is suitable for elderly patients with irreparable cuff tears and medical co-morbidities.

Project description:PurposeTo determine the clinical, biomechanical, and financial impact of the use of subacromial balloon spacers in the surgical management of massive, irreparable rotator cuff tears (RCTs).MethodsAll studies assessing the use of implantable subacromial balloon spacers for management of massive, irreparable RCTs were systematically searched. Risk of bias was assessed using Methodological Index for Non-Randomized Studies criteria. Data extraction and analysis was performed for pain and function scores, shoulder range of motion (ROM), glenohumeral contact pressure and vertical migration of humeral head, and cost. Subjective synthesis was performed with forest plots when outcomes were reported in 3 or more studies.ResultsIn total, 19 studies met inclusion criteria for analysis; 337 patients (mean age 68 years) had 343 subacromial balloon spacer implantations. Throughout a mean follow-up of 33 months, there was significant improvement in the Total Constant Score (preoperative: 22.5-41.8; postoperative: 51.4-72.3), Oxford Shoulder Score (preoperative: 21.3-26; postoperative: 34.39-48.2), American Shoulder and Elbow Surgeons score (preoperative: 24.5-59.1; postoperative: 72.5-85.7), and shoulder ROM parameters. Subacromial balloon spacer placement resisted superior humeral head migration (range of preoperative to postoperative difference: 2.8-6.2 mm) and decreased peak subacromial pressure during shoulder ROM.ConclusionsExisting literature of subacromial balloon spacers has a high risk of bias, lack of appropriate control, and low levels of evidence. A qualitative synthesis indicates that subacromial balloon spacer implantation in patients with massive irreparable RCTs is cost-effective and leads to improved function (Total Constant Score and Oxford Shoulder Score) and ROM. In cadaveric studies, subacromial balloon spacers resist superior humeral head migration and reduce subacromial pressure. The theoretical risk of biodegradation of the balloon spacer has not been substantiated in study of up to 5-years follow-up, and the risk of complications from this procedure appears to be minimal.Level of evidenceIV; Systematic review of level III-IV studies.

Project description:BackgroundSynovitis of the glenohumeral (GH) joint and the subacromial (SA) space is commonly observed during arthroscopic rotator cuff surgery.PurposeTo investigate the distribution, severity, and clinical implications of synovitis in the GH joint and SA space in patients with a full-thickness rotator cuff tear (RCT).Study designCase series; Level of evidence, 4.MethodsData were retrospectively collected from 207 patients with a full-thickness RCT who underwent arthroscopic repair. Preoperative parameters used in the clinical assessment included pain, range of motion (ROM), muscle strength, and functional scores. Macroscopic assessment of synovitis was performed intraoperatively in the 3 regions of interest (ROIs) of the GH joint and 4 ROIS of the SA space using an evaluation system. The distribution and severity of synovitis and the association between synovitis and clinical assessment were evaluated.ResultsSynovitis was more severe in the GH joint than in the SA space (P < .001). Synovitis in the posterior GH joint and the lateral SA space, where most of the rotator cuff was located, was the most severe area among the ROIs of the GH joint and the SA space, respectively (P < .05). All types of pain, except for pain at rest, were associated with synovitis in the posterior GH joint (P < .05). All ROM measures were associated with synovitis in the posterior and inferior GH joint (|r| > 0.20; P < .05 for both). The strength of the supraspinatus and the infraspinatus was associated with synovitis in the posterior GH joint (P < .05). Shoulder function was associated with synovitis in the posterior and inferior GH joint and more in the posterior GH joint (P < .05 for both). Synovitis in the SA space was not associated with any of the clinical parameters.ConclusionSynovitis in the posterior GH joint was the most severe form of synovitis in the GH joint in patients with a full-thickness RCT. Synovitis in the posterior GH joint was closely associated with increased pain and decreased ROM, muscle strength, and functional score. Synovitis in the SA space was milder and not associated with any clinical parameters.
