Unlabelled: Subcoracoid impingement syndrome is a rare and underrecognized cause of anterior shoulder pain. Currently, subcoracoid impingement syndrome is understood to involve impingement of anatomic structures such as the subcoracoid bursa and subscapularis tendon within the coracohumeral space, and there are no reports of sonographic findings in subcoracoid impingement syndrome other than the impingement of thickened subscapularis bursa. Here we report a case of subcoracoid impingement syndrome, including a novel sonographic finding, arthroscopic findings, and a proposed pathophysiology.

Level Of Evidence: V.

Analysis of the therapeutic efficacy of arthroscopic repair of the subscapularis tendon combined with coracoplasty.

Sci Rep

January 2025

Department of Orthopedics, The Third Affiliated Hospital of Anhui Medical University, The First People's Hospital of Hefei), 390 Huaihe Road, Hefei, 230061, Anhui, China.

The aim of this study was to analyze the outcomes of arthroscopic subscapularis tendon repair combined with coracoplasty in the treatment. The study involved 80 patients (46 males, 34 females; aged 33 to 73 years), who underwent arthroscopic repair for subscapularis tears (type I, II, and III) presenting symptoms of anterior shoulder pain and tenderness. Subcoracoid impingement was defined as a coracohumeral distance of less than 6 mm on preoperative magnetic resonance imaging, with a follow-up of was at least two years.

Hypothesis And Background: Reverse shoulder arthroplasty (RSA) exhibits favorable outcomes in managing rotator cuff arthropathy, primary glenohumeral arthritis, and complex proximal humeral fractures. Despite its success and reliability, certain patients experience persistent pain and stiffness. The clinical utility of therapeutic arthroscopy in RSA patients remains an area for investigation.

Subcoracoid impingement occurs due to mechanical encroachment of the subscapularis tendon in the subcoracoid space between the coracoid process and lesser tuberosity of the humerus. Although physical therapy is known to have a crucial role in managing this condition, to the best of our knowledge, there is no established physical therapy program in the literature. This case report aims to provide a detailed presentation and diagnosis of a subcoracoid impingement case and to investigate the effects of physical therapy on pain, disability, performance, muscle strength, and ultrasound measurements over a one-year follow-up period.

Article Synopsis
  • The study investigates the relationship between subcoracoid bursa (SCB) effusion and factors like rotator cuff tears (RCT) using MRI in patients with shoulder pain.
  • Out of 80 analyzed shoulders, 41.3% exhibited SCB effusion, with RCT being significantly associated with SCB effusion presence.
  • The size of the SCB effusion was larger in shoulders with RCT compared to those without, indicating possible pathological links in shoulder conditions.

Article Synopsis
  • The Trillat procedure, developed by Albert Trillat, is one of the earliest techniques for treating recurrent anterior shoulder instability, utilizing unique biomechanical strategies that enhance the shoulder's stability.
  • This procedure involves modifying the coracoid process and changing the subscapularis muscle's function, reinforcing its role in stabilizing the humeral head and preventing dislocation.
  • Though modern techniques like arthroscopic Bankart repair are more commonly used, the Trillat procedure is still relevant, especially for older patients with large cuff tears or younger ones with hyperlaxity, albeit with potential complications such as pain, reduced motion, and impingement.
