AI Article Synopsis
- Of 823 pediatric hand fractures studied, only 11 (1.3%) were classified as Salter-Harris type III fractures of the proximal phalanx, highlighting their rarity.
- The average age of patients with these fractures was 14.9 years, and most cases involved displaced fractures that required open reduction and internal fixation for treatment.
- At a follow-up of 21 months, most patients achieved full joint motion and normal function, demonstrating that proper reduction and fixation are crucial for successful outcomes in these types of injuries.
Article Abstract
Of 823 pediatric hand fractures treated between 1981 through 1996, only 11 (1.3%) were Salter-Harris type III fractures of the proximal phalanx. We review the anatomic basis, etiology, age prevalence, treatment, and results of these epiphyseal injuries. The average age at injury was 14.9 years, with a narrow range from 14 years 2 months to 15 years 11 months. Nine of 11 fractures were displaced and treated with open reduction and internal fixation. At an average follow-up of 21 months, 9 of 11 had full joint motion. The other two had minimal loss of motion, and all had normal function and collateral ligament stability. The displacement and size of the epiphyseal fragment, avulsed and rotated by the collateral ligament, are often underestimated by radiographs. We found that anatomic reduction and fixation yielded good results in all displaced fractures. This restores both the stability of the collateral ligament and a smooth articular surface.

Introduction: Extraarticular deformity (EAD) with knee arthritis is a complex condition involving tri-planar bone deformity with pathological malalignment and chronic soft tissue contracture or laxity in the knee joint. Intraarticular correction by TKA, which was previously performed with conventional manual jig by mechanical alignment technique, had its limits and difficulties especially extensive soft tissue release and risk of jeopardizing the collateral ligaments. Robotic technology allows for reproducible and precise execution of surgical plan and allows adjustment to various new personalised alignment philosophy including functional alignment (FA).

Introduction: Olecranon fractures account for 5-7% of elbow fractures, making them a common injury. The majority of these fractures are treated surgically because they are intra-articular and can disrupt the elbow extensor mechanism. Mayo Type II fractures are displaced with a stable ulnohumeral joint, indicating intact ligamentous structures, particularly the anterior portion of the medial collateral ligament.

Background: To compare the clinical outcomes of inferior extensor retinaculum (IER) augmentation following repair of the anterior talofibular ligament (ATFL) with isolated ATFL repair in patients with an arthroscopically confirmed grade 3 lesion of the ATFL.
Methods: We conducted a retrospective study of consecutive chronic lateral ankle instability (CLAI) patients who underwent arthroscopic ATFL repair between March 2018 and August 2022. The average age of the patients was 31.

Department of Orthopaedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea.
Background: The aim of surgical treatment for posterolateral rotatory instability (PLRI) of the elbow is to restore the integrity of the lateral ulnar collateral ligament (LUCL), with ligamentous reconstruction being the preferred option for recurrent symptomatic PLRI. However, there is no clinical evidence demonstrating the superiority of reconstruction versus repair. Treatment options currently depend on the cause of the LUCL injury and surgeon preference.
