Subtrochanteric fractures are fraught with certain anatomic, biologic and biomechanical challenges. One unique case of implant failure with varus nonunion was encountered following repeat trauma. NLM 29 men and 14 women aged 25 to 65 (mean, 44) years with comminuted subtrochanteric femoral fractures underwent indirect reduction and mini-incision DCS fixation. We studied the dynamic condylar screw DCS as an implant on a series of 30 consecutive patients with subtrochanteric fractures. 3. Although this device was designed for use in the distal femur, it has features which make it attractive for use in subtrochanteric fractures.

To study the results of 48 patients with subtrochanteric fractures of the femur, treated surgically with fixation by dynamic hip screw [DHS] in 25 patients [52%], and by dynamic condylar screw [DCS] in 23 patients [48%], at Al-Razi Orthopaedic Hospital in the period between January 1990 and June 1995. In osteoporotic bone, five screws (10 cortices) are advised. Thirty-two consecutive subtrochanteric femur fractures were treated using the 95° dynamic condylar screw between 1982 and 1985. Arch Orthop Trauma Surg. Methods. Screw available holes: 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140 and 145. All cases were treated using the principles of strict indirect reduction to achieve anatomic alignment rather than anatomic reduction, with no bone grafting, and delayed weight bearing. Five patients died before fracture healing. A consecutive series of 58 patients, treated with the dynamic condylar screw (DCS) for subtrochanteric fractures were retrospectively reviewed. Purpose. [5,6] DCS act as static and rigid implant in pure subtrochanteric fractures whereas biomechanical changes Subtrochanteric fractures are fraught with certain anatomic, biologic and biomechanical challenges.

Ten out of 11 young patients, (nine with high-energy injuries), united primarily. The advantages of the implant and technique are a simplified procedure, shorter operative time, and rapid union. Injury. Using the DCS with the indirect reduction method and delayed weight bearing is an acceptable choice in subtrochanteric femur fractures with greater trochanteric involvement when other adequate implants are not available for stable fixation. Arch Orthop Trauma Surg. The use of a dynamic condylar screw and biological reduction techniques for subtrochanteric femur fracture. A study was designed to examine the outcomes of patients with closed comminuted subtrochanteric femoral fractures fixed with a dynamic condylar screw (DCS) and using biological (indirect) reduction techniques at a tertiary referral centre.Thirty-one consecutive patients with a mean age of 32.6 years, who sustained subtrochanteric femoral fractures, were treated with this method. In 2003- Vaidya SV., Dholakia DB., Chatterjee A.32 demonstrated the use of a dynamic condylar screw and biological reduction techniques for subtrochanteric femur fracture. Various implants used to address these fractures are 95 degree blade plate, 95 degree dynamic condylar screw, reconstruction nails and proximal femoral locking plate. 2.

NLM Using the DCS with the indirect reduction method and delayed weight bearing is an acceptable choice in subtrochanteric femur fractures with greater trochanteric involvement when other adequate implants are not available for stable fixation. The inclusion criteria was closed subtrochanteric fractures in adults of both gender aged 20 years or above; pathological fractures and open fractures were excluded from the study. Unfallchirurg. One should aim to have at least five screw holes distal to the fracture since one needs eight cortices of screw purchase to ensure adequate fixation. 2003 Feb. 34 (2):123-8. . The overall union rate was 93.7% (15 of 16). Methods. A consecutive series of 58 patients, treated with the dynamic condylar screw (DCS) for subtrochanteric fractures were retrospectively reviewed. doi: 10.1016/S0020-1383(17)30498-9. All cases were treated using the principles of strict indirect reduction to achieve anatomic alignment rather than anatomic reduction, with no bone grafting, and delayed weight bearing. [Trochanteric femoral fractures: anatomy, biomechanics and choice of implants]. The length of the plate is determined by the extent of the fracture. Five patients died before fracture healing. To determine operative risk in subtrochanteric fracture treated with proximal femoral nail, dynamic hip screw and dynamic condylar screw. Dynamic Condylar Screw (DCS Screw) is designed to provide strong and stable internal fixation of certain distal femoral and subtrochanteric fractures, with minimal soft tissue irritation. All cases were treated using the principles of strict indirect reduction to achieve anatomic alignment rather than anatomic reduction, with no bone grafting, and delayed weight bearing.
