Article Abstract

Background: The unique anatomy and biomechanics of the distal humerus make distal humeral shaft fractures a significant challenge in orthopedic surgery. Conventional posterior surgical approaches are associated with risks such as iatrogenic radial nerve injury and increased soft tissue trauma.

Objective: This study aimed to assess the clinical efficacy of an inverted PHILOS plate using an anterior minimally invasive percutaneous approach for treating distal humeral shaft fractures.

Methods: We enrolled 32 patients with distal humeral shaft fractures. The surgical technique involved an anterior minimally invasive percutaneous application of an inverted PHILOS plate. Outcome measures included operative time, intraoperative blood loss, incision length, fracture healing time, and functional scores (Constant-Murley and Mayo Elbow Performance Scores). Postoperative complications, including nerve injury and nonunion, were documented.

Results: The mean operative time was 1.69 ± 0.66 h, with a median blood loss of 50 ml (IQR: 50-100 ml). The mean incision length was 10.9 ± 1.78 cm, and the mean time to fracture healing was 11.2 ± 3.68 weeks. Functional outcomes were satisfactory, with a mean Constant shoulder score of 92.69 ± 6.6 and a mean Mayo Elbow Performance Score of 91.4 ± 8.04. No instances of iatrogenic nerve injury or nonunion were observed.

Conclusion: The anterior minimally invasive percutaneous approach using an inverted PHILOS plate is an effective method for treating distal humeral shaft fractures. This technique minimizes soft tissue damage, reduces the risk of iatrogenic radial nerve injury, and ensures reliable fracture stabilization, thus offering a promising alternative to conventional posterior approaches.

Introduction/background: Complex articular fractures around the knee in the elderly patient present an ongoing challenge regarding optimal treatment. While extensive research has evaluated immediate arthroplasty following fracture of the proximal femur, distal femur, proximal humerus, and elbow, relatively little focus has been given to immediate arthroplasty following complex tibia plateau fractures.

Methods: As seen with many other fractures, arthroplasty can shorten recovery and hospital stay and allow early weight-bearing with improved mobility while minimizing complications and possible future conversion arthroplasty cost.

Recurrent anterior instability with glenoid bone loss is a difficult problem with several surgical options. The Latarjet technique remains the gold standard for glenoid bone reconstruction in the setting of critical glenoid bone loss with excellent long-term outcomes. However, this technique has well known downsides including high rates of complications.

From the Harvard Medical School Orthopaedic Trauma Initiative, Boston, MA (Mr. Musick, Wagner, Gregg, Muhammad, Policicchio, Wang, Bhashyam, Stenquist, Harris, Ly, and Aneja), the Department of Orthopaedic Surgery, Massachusetts General Hospital, Boston, MA (Mr. Musick, Wagner, Booth, Gregg, Muhamma

Introduction: The purpose of this study was to determine the rate of conversion to total elbow arthroplasty (TEA) following open reduction and internal fixation (ORIF) with olecranon osteotomy for intraarticular distal humerus fractures.

Methods: This retrospective case series included adult patients who underwent ORIF with olecranon osteotomy for AO/OTA 13C distal humerus fractures between January 2010 and April 2024 at two academic level 1 trauma centers. The primary outcome was the rate of conversion to TEA.

Background: Joint denervation procedures continue to demonstrate promise in the management of chronic pain and functional improvement in joint pathology of the hand and wrist. As our understanding of these techniques evolves, a detailed comprehension of neuroanatomy, including the precise relationships and contributions of sensory innervation to targeted joints, is critical for optimizing outcomes.

Methods: Freshly thawed frozen upper extremity cadaveric specimens were analyzed under the direction of two fellowship-trained hand surgeons.

Context: Lifestyle habits, such as exercise, alcohol consumption, and smoking, are known to be closely associated with the risk of osteoporotic fracture. However, little is known regarding the association between osteoporotic fracture and dietary habits such as skipping breakfast and having a late dinner.

Objective: This study aimed to examine the association between lifestyle habits, including diet, and the risk of osteoporotic fracture.
