AI Article Synopsis
- - The study aimed to compare the effectiveness of two fixation methods—lag screw fixation (LSF) and Kirschner wire fixation (KWF)—for treating triplane distal tibia epiphyseal fractures in children.
- - A retrospective analysis of 25 cases showed that both methods resulted in improved AOFAS scores over time; however, LSF had a lower rate of premature epiphyseal closure (PPC) compared to KWF, which reported 4 cases of PPC.
- - The conclusion indicated that while both techniques yield good clinical results, LSF offers better outcomes regarding PPC, whereas KWF has the advantage of requiring less anesthesia and surgery time.
Article Abstract
Objective: To compare the mid-term clinical results of lag screw and Kirschner wire fixation(KWF) for close reduction in triplane distal tibia epiphyseal fracture.
Methods: A retrospective analysis of 25 cases of triplane fractures of the distal tibia treated in our department from Jan 2017 to Dec 2019 was performed, Lag screw fixation(LSF) was used in 14 cases and Kirschner wire fixation in 11 cases, the clinical results were evaluated by premature epiphyseal closure(PPC) rate, the American Orthopaedic Foot and Ankle Score (AOFAS) Ankle-hindfoot foot scoring system, the lateral distal tibial angle (LDTA) from X-ray.
Results: All the 25 children were followed up for a mean of 34(ranging 26-52) months. AOFAS scores improved from a mean of 33(ranging 29-43) pre-op, to 82(ranging 77-88) at three month follow up, to 92 (ranging 88-98) at last follow-up in all 25 cases. Till last follow up there was no cases premature physeal closure in LSF group but 4 cases in KWF group, LDTA in both groups at last follow up shows no ankle varus or valgus deformity, and the ankle joint function was not limited in all cases.
Conclusion: Lag screw and Kirschner wire fixation methods can both achieve good clinical effects for triplane distal tibia epiphyseal fracture. Lag screw fixation provide lower PPC rate but Kirschner wire fixation save one anesthesia and surgery.

Subtrochanteric fractures in older patients are typically due to low-energy falls. The standard of care is intramedullary nailing. The Smith & Nephew Trigen Intertan (Memphis, TN, US) is an intramedullary nail with a novel design that incorporates two integrated compression screws.

Objective: Despite several surgical options, there has yet to be a consensus on the best treatment for femoral neck fracture (FNF) due to higher complication rates compared to other bone fractures. This study aims to examine the possible consequences and solution suggestions of changing screws during surgery for various reasons in FNF surgical treatment from a biomechanical perspective.
Method: FNF and treatment materials were analyzed biomechanically using a package program based on the finite element method (FEM).

Background: This study aimed to analyze the files of patients treated using PFN-A or INTERTAN intramedullary nails to reveal additional superiorities or disadvantageous factors for selecting the better intramedullary fixation method in patients presenting with intertrochanteric femur fractures.
Methods: In this retrospective study, the files of the patients who were operated on for intertrochanteric femur fractures using intramedullary fixation methods between September 2010 and June 2015 in the Orthopedics and Traumatology Clinic, Çukurova University Faculty of Medicine, were reviewed. The data including age, gender, chronic diseases, causes of fractures, fracture classification based on Arbeitsgemeinschaft für Osteosynthesefragen (AO), the nail type (long or short), the interval between trauma and surgery, duration of anesthesia and surgery, hospitalization duration, amount of blood transfusion, the Tip-Apex Distance (TAD) in postoperative radiographs, functional outcomes according to Harris Hip Score (HHS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), postoperative complications, need for revision, and mortality was noted.

Background: Extra-articular but severely comminuted distal basal fractures of the proximal phalanx (PP) are rarely reported. Therefore, the aim of this study was to achieve proper union and desirable outcomes using low-profile locking plates/screws. We introduced our own surgical approach and reported the clinical/radiographic outcomes via retrospective case series.
