Article Abstract
Posterolateral rotatory instability (PLRI) of the elbow occurs from chronic lateral ulnar collateral ligament (LUCL) injury leading to subluxation of the ulnohumeral joint and radial head. Patients with failed or untreated LUCL injury can go on to have chronic elbow instability and difficulty with activities that require an axial load on the elbow. Free grafts such as semitendinosus, Achilles, or palmaris longus require fixation on both the humerus and ulna, or may not represent the native LUCL kinematics as a native tendon such as anconeus. Split anconeus fascia transfer is a surgical treatment option for PLRI that does not require ulnar drilling or graft site morbidity. This surgical technique paper describes evaluation, management, and treatment of PLRI with accompanying video and description of the split anconeus fascia transfer technique.

Background: The split anconeus fascia transfer (SAFT) is an option for reconstruction of the lateral ulnar collateral ligament (LUCL) in chronic posterolateral rotatory instability (PLRI) of the elbow with potential advantages of using only local tissue within the surgical exposure and not requiring ulnar fixation. This study aimed to assess SAFT strength compared to a traditional free graft reconstruction in a PLRI biomechanical model.
Methods: To measure biomechanical strength, eight cadaveric upper extremity pairs were utilized.

Article Synopsis
- Osteochondritis dissecans (OCD) in the humeral capitellum is a common issue for young athletes, often requiring surgical intervention through various approaches to treat unstable lesions.* -
- The study compared three surgical methods—Kocher, posterior anconeus-splitting, and Wrightington approaches—on cadaveric elbows to evaluate how much of the humeral capitellum's articular surface could be properly accessed for treatment.* -
- Results showed that the anconeus-splitting approach provides superior exposure (74%) compared to Kocher (49%), while the Wrightington approach allowed for full access (93%) to the articular surface, indicating that a combination of methods may be optimal for
Transdeltoid Approach to Axillary Nerve Repair: Anatomical Study and Case Series.

Article Synopsis
- The study explores a new surgical method to access the anterior division of the axillary nerve (ADAN) in patients with isolated axillary nerve injuries, focusing on a deltoid-splitting approach for dissection.
- Involving nine patients, the clinical investigation included nerve grafting and muscle transfer techniques to repair the nerve damage, successfully demonstrating the anatomy and trajectory of the ADAN.
- Results showed effective reinnervation with varying muscle strength post-surgery, indicating that this new approach is a practical option for treating such nerve injuries.
Osteochondral Autograft Transplantation for Capitellar Osteochondritis Dissecans.

Shriners Hospitals for Children, Philadelphia, Pennsylvania.
Background: The goal of the osteochondral autograft transplantation (OAT) procedure is to replace both the bone and cartilage that have been compromised by osteonecrosis of the capitellum, a condition known as osteochondritis dissecans (OCD). In children, the vascularity of the capitellum is limited compared with that in adults because the physis acts as a physical barrier to vascular ingrowth from the metaphysis to the epiphysis. The necrotic subchondral bone cannot keep up with the weight-bearing demands of certain high-level athletes such as gymnasts, accumulating microfractures and eventually crumbling.
