Eaton-Littler ligamentoplasty has proven its efficacy in the treatment of trapeziometacarpal (TMC) instability.  In this article, we describe the arthroscopically assisted Eaton-Littler ligamentoplasty through two clinical cases.  Arthroscopy is used to accurately place the metacarpal bone tunnel and pass the slip of flexor carpi radialis tendon in the latter. This procedure avoids soft-tissue dissection and could improve the outcome of this well-known surgery.  The two clinical cases showed good short-term outcome with a decrease of pain and good function.  Arthroscopy to assist Eaton-Littler TMC ligamentoplasty is technically feasible, allowing a less invasive surgery. A larger prospective controlled study with a longer term outcome is mandatory to assess the real advantages of this modified procedure.

Scapular morphological attributes show promise as prognostic indicators of retear following rotator cuff repair. Current evaluation techniques using single-slice magnetic-resonance imaging (MRI) are, however, prone to error, while more accurate computed tomography (CT)-based three-dimensional techniques, are limited by cost and radiation exposure. In this study we propose deep learning-based methods that enable automatic scapular morphological analysis from diagnostic MRI despite the anisotropic resolution and reduced field of view, compared to CT.

Lower trapezius tendon transfer is a surgical procedure that has become increasingly popular in recent years. The biggest advantage of this method is that the pulling direction of the lower trapezius is the same as that of the infraspinatus. Thus, the transferred lower trapezius tendon can biomechanically mimic the functions of the posterior-superior rotator cuff.

Background: Developmental dysplasia of the hip (DDH) encompasses a spectrum of pathological conditions, including dislocation, subluxation, and deformities of the femoral head and acetabulum. The optimal surgical approach for DDH remains a subject of debate. Successful treatment aims to achieve a stable concentric reduction and prevent future subluxation or dislocation.

Background: Bennett's fracture, a fracture-dislocation of the base of the first metacarpal, poses significant challenges due to the unique biomechanics of the thumb's carpometacarpal (CMC) joint. Effective management is critical to restoring thumb function and preventing long-term complications such as arthritis and instability.

Objective: This article provides a comprehensive overview of Bennett's fracture, including its mechanism of injury, diagnostic considerations, and management strategies, with a focus on conservative and surgical options.

The lateral collateral ligament complex of the elbow is pivotal for maintaining the stability of the elbow joint. The open technique for reconstructing the lateral ulnar collateral ligament (LUCL) is a standard procedure to treat elbow instability caused by LUCL deficiency. Nevertheless, as arthroscopy procedures in the elbow have advanced, we describe an arthroscopic technique to reconstruct the LUCL with suture anchors and bone tunnel techniques.
