A new plate is presented for internal fixation of valgus intertrochanteric osteotomy. This plate enables a controlled translation, permits dynamic compression of the osteotomy line and eludes some of the complications involved in the use of other double-angle plates. The morphological characteristics of the plate as well as its technical and surgical aspects are described. A follow-up study of 63 patients operated on between January 1978 and June 1980 has been carried out, underlining some of the mistakes that can affect the healing time.

Five states of reduction in OTA/AO A1.3 intertrochanteric fractures of the femur a biomechanical study.
BMC Musculoskelet Disord

Department of Pathology, Jining No. 1 People's Hospital, Jining City, Shandong Province, 272011, China.
Article Synopsis
- - This study investigates how different reduction conditions affect the mechanical stability of OTA/AO 31A1.3 intertrochanteric fractures using artificial femur models.
- - Twenty models were tested under five reduction states (positive support, neutral support, negative support, varus fixation, and valgus fixation), revealing significant differences in subsidence displacement and axial stiffness among these groups.
- - The findings indicate that positive support offers the best mechanical stability for these fractures, suggesting it should be the preferred surgical approach, while varus fixation should be avoided for better stability outcomes.
Pilot study of three novel implants-GSK triangular system, locking hip screw and controlled sliding dynamic hip screw, for fixation of fracture of the neck of femur.

Department of Orthopaedics, P.G.I Swasthiyog Pratishthan, Miraj, Maharashtra, India.
Article Synopsis
- The study explored the treatment of intra capsular fractures of the neck of femur (FNF) using three novel fixation systems aimed at reducing complications and reoperation rates associated with traditional methods.
- Researchers hypothesized that achieving absolute stability through different implant systems is essential based on the patient's age and bone condition, with specific devices designed for young, healthy individuals versus elderly patients with osteoporosis.
- Results showed a high union rate of 95.2% among the 42 patients studied, with some complications noted, including avascular necrosis in three patients and one instance of deep infection, but overall, the new systems were effective in promoting healing.
Background Intracapsular femoral neck fractures account for a majority of hip fractures. This study aimed to investigate the efficacy of valgus osteotomy as a primary treatment for intracapsular femoral neck fractures in adult patients aged 15-60 years, assessing its impact on functional outcomes and fracture union. Methodology A retrospective clinical analysis was conducted at the Department of Orthopedics and Traumatology, Osmania Government General Hospital, Hyderabad, India, focusing on patients treated with primary intertrochanteric valgus osteotomy for intracapsular femoral neck fractures.

Article Synopsis
- - The study investigates the outcomes of using the femoral neck system (FNS) for fixing displaced femoral neck fractures (FNFs), as previous research has limited data on this method's effectiveness.
- - A total of 43 patients were analyzed, mostly young males, with a few experiencing complications like deep infections and nonunion, resulting in some requiring additional surgeries.
- - The findings indicate an 18% reoperation rate with the FNS, which is lower than the rates associated with other internal fixation methods, suggesting that the FNS may be a safer and more effective treatment option for FNFs.
Proximal femoral valgus osteotomy for the treatment of developmental coxa vara: a systematic review of the literature.

Background: Developmental Coxa Vara (DCV) consists on a pathological reduction in head-shaft angle (HSA) and increased femoral retroversion. Several case series reported outcomes on proximal femoral valgus osteotomy (PFVO), but no evidence synthesis had been conducted. This systematic review aimed to (1) analyze success rate and complications, (2) report the degree of correction according to the HSA and the Hilgenreiner Epiphyseal Angle (HEA), compare success rate and degree of correction of subtrochanteric (SVO) vs intertrochanteric (IVO) osteotomy, and (4) difference in success rate and correction between patients in which an internal (IF) or external fixation (EF) technique was used.
