Abstract

Background: Irreparable massive rotator cuff tears (IMRCTs) present substantial treatment challenges, highlighting the necessity of making effective treatments available.

Objective: To evaluate the biomechanical characteristics of a modified procedure of superior capsule reconstruction (mSCR) employing the autologous peroneus longus tendon for the treatment of irreparable massive rotator-cuff tears (IMRCTs), encompassing the entire supraspinatus tendon and 50% of the infraspinatus tendon.

Methods: Seven cadaveric specimens were tested at 0°, 30°, and 60° glenohumeral abduction under the following three conditions: (1) intact, (2) IMRCT, and (3) mSCR using the autologous peroneus longus tendon. Humeral rotational range of motion (ROM), superior translation of the humeral head, and subacromial contact pressure were measured. Repeated-measures ANOVA was followed by Tukey's post hoc test to perform statistical analyses.

Results: At all the abduction angles, superior translation of the humeral head and subacromial contact pressure were higher in the IMRCT group than in the intact group but were significantly lower in the mSCR group than in the IMRCT group. All these differences were statistically significant (P < 0.05).

Conclusion: The mSCR procedure can reduce the superior translation of the humeral head and subacromial contact pressure without limiting humeral ROM in IMRCTs. Utilizing mSCR with the peroneus longus tendon may serve as a therapeutic approach for IMRCTs.

期刊介绍： The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty. In each issue clinicians can find information which they can use in their patient setting the very next day.
