Background: Redundancy of the anteromedial capsule of the shoulder may persist despite proper tensioning of the capsule and repair of a Bankart lesion during an anteroinferior capsular shift procedure.
Hypothesis: A barrel-stitch suture technique incorporated into a capsular shift procedure is effective in achieving satisfactory shoulder stability.
Study Design: Uncontrolled retrospective review.
Methods: A barrel-stitch technique was used for patients identified as having anteromedial capsular redundancy during a capsular shift procedure for anteroinferior instability.
Results: The incidence of anteromedial capsular redundancy and labral deficiency was 49% (38 of 78). Patients with anteromedial capsular redundancy had a significantly greater number of dislocations before surgery (16.1 +/- 21.3 versus 7.4 +/- 7.4) and a greater duration of symptoms (79.8 +/- 84.2 versus 31.6 +/- 32.2 months). The mean postoperative Rowe score of patients with anteromedial capsular redundancy was 88.7 +/- 14.8, with 92% having excellent or good results, compared with 88.9 +/- 14.8 in the remaining patients and 93% excellent or good results.
Conclusions: Anteromedial capsular redundancy is associated with longer preoperative duration of symptoms and more dislocations, but effective treatment can be achieved with a capsular shift procedure augmented with medial capsular imbrication with a barrel stitch.

Highly extensile approach for comminuted ulna coronoid process fractures with mini-plate fixation: a case series of 31 patients.
BMC Musculoskelet Disord
July 2024
Orthopaedic Medical Center, The Second Hospital of Jilin University, No. 218, Ziqiang Street, Nanguan District, Jilin, Changchun, People's Republic of China.
Background: For the treatment of coronoid process fractures, medial, lateral, anterior, anteromedial, and posterior approaches have been increasingly reported; however, there is no general consensus on the method of fixation of coronal fractures. Here, we present a highly-extensile minimally invasive approach to treat coronoid process fractures using a mini-plate that can achieve anatomic reduction, stable fixation, and anterior capsular repair. Further, the study aimed to determine the complication rate of the anterior minimally invasive approach and to evaluate functional and clinical patient-reported outcomes during follow-up.

Introduction: Elbow dislocations, particularly those associated with varus posteromedial rotary instability, are relatively uncommon. We present the case of a 25-year-old male initially managed nonoperatively for a posterior elbow dislocation, who subsequently experienced irreducible re-dislocation with characteristic fractures of the anteromedial facet and tip of the coronoid, indicative of varus posteromedial rotary instability.
Case Report: Following an unsuccessful attempt at closed reduction under general anesthesia, open reduction was performed, revealing the interposition of the posterior capsule of the humero-ulnar joint as the cause of irreducibility.
Puncture Capsulotomy Technique During Hip Arthroscopy.

Department of Orthopaedics, Sports Medicine Center, Massachusetts General Hospital, Mass General Brigham, Boston, Massachusetts.
Article Synopsis
- The interportal and T-capsulotomy techniques used in hip arthroscopy can weaken the hip's stability by disrupting the iliofemoral ligament, potentially leading to complications like dislocation and pain.
- * A new minimally invasive puncture capsulotomy technique has been developed to avoid damaging the hip capsule, preserving its biomechanics while still allowing for effective joint visualization.
- * The procedure involves careful positioning and fluid distention to minimize risks, with specific portal placements guided by fluoroscopy and arthroscopic techniques.
The Anterior Fibers of the Superficial MCL and the ACL Restrain Anteromedial Rotatory Instability.

Background: There is limited knowledge about how the anterior cruciate ligament (ACL) and capsuloligamentous structures on the medial side of the knee act to control anteromedial rotatory knee instability.
Purpose: To investigate the contribution of the medial retinaculum, capsular structures (anteromedial capsule, deep medial collateral ligament [MCL], and posterior oblique ligament), and different fiber regions of the superficial MCL to restraining knee laxity, including anteromedial rotatory instability.
Study Design: Controlled laboratory study.

Existing studies lack a clear understanding of the interaction of the joint capsule with surrounding tissues and the local mechanical environment. Particularly, a finite element model of human elbow joint incorporating active behavior of muscle was constructed. The simulation was performed during the elbow joint flexion movement under different injury conditions of capsule (anterior capsule, posterior capsule, medial anterior capsule, lateral anterior capsule, medial posterior capsule, and lateral posterior capsule).
