dynamic condylar trochanteric

Trochanteric hip fractures have become very common with 35-40% of these fractures being unstable. Trochanteric fractures, especially unstable ones are associated with high rates of mortality and morbidity and thus remain an inordinate challenge for surgeon to treat these fractures with proper choice of implant. Aim of the study was to compare the proximal femoral nail and dynamic condylar screw in the management of unstable trochanteric fractures. Our study was a prospective comparative study which included 26 patients with fresh (≤3 weeks old) unstable trochanteric fractures AO 31A2 and AO 31A3, with age ≥18 years of both sexes...

INTRODUCTION: Nonunions of trochanteric femoral fractures are uncommon due to a good blood supply of the cancellous bone of the trochanteric region. Nevertheless, if a nonunion occurs, complex revision procedures usually become necessary. The purpose of this study was to evaluate a series of aseptic trochanteric nonunions in patients aged 60 years or older, looking at outcomes regarding healing rate, implant-related complications and secondary surgeries. MATERIAL AND METHODS: We conducted a retrospective chart review of patients with aseptic femoral trochanteric nonunions aged over 60 years...

A 40-year-male treated with hip screw for unstable inter trochanteric fracture femur, had an implant failure after an aggressive therapy session .The Dynamic Condylar Screw was removed and fracture was fixed with Proximal Femoral Nail. The nail also failed to achieve its goal of fracture union, as a result of a unique type of reverse Z effect, in contradiction to expected Z effect resulting in intrapelvic migration of proximal hip lag screw of the proximal femoral nail.

BACKGROUND: Unstable intertrochanteric fractures of the hip, especially reverse oblique fractures are a serious problem in traumatology, as there is no standard method of treatment and inadequate treatment carries a significant complication rate. To assess the surgical treatment results of reverse oblique trochanteric fractures. MATERIAL/METHODS: Between 1997-2010, 389 patients with intertrochanteric fractures were treated. 28 (7.1%) of these fractures classified as reverse oblique...

A 14-year-old boy presented with a 2-month history of left groin pain and a limp on the left side. Radiographs confirmed slipped capital femoral epiphysis (SCFE) of the left hip. The surgical procedure he received used a single, 8-mm, partially threaded, cannulated screw. Postoperatively he was advised to remain strictly non-weight bearing on the affected lower limb until physeal closure was achieved. Unfortunately, he fell down 4 weeks postoperatively and sustained a subtrochanteric fracture on the same hip, with the cannulated screw still in place...

BACKGROUND: Reverse oblique trochanteric fracture of femur is a distinct fracture pattern. 95° Dynamic condylar screw (DCS) and proximal femoral nail (PFN) are currently the most commonly used implants for its fixation. This study aims to biomechanically compare the cutout resistance as well as modes of failure of DCS and PFN in reverse oblique trochanteric fractures. MATERIALS AND METHODS: Sixteen freshly harvested cadaveric proximal femoral specimens were randomly assigned to three mean bone mineral density matched groups, eight of which were implanted with 95° DCS and the other eight with PFN...

The aim of this study was the biomechanical evaluation of the reversed less invasive stabilization system (LISS) internal fixation as a joint-preserving salvage procedure for trochanteric fractures. Five LISS plates and five dynamic condylar screws (DCS) were tested using synthetic femora (Sawbones) with an osteotomy model similar to a type-A2.3 pertrochanteric fracture. The constructs were subjected to axial loading up to 1000 N for five cycles. Then, the force was continuously increased until fixation failure...

The goal of this research was to find the implant which would provide a better possibility of the fractured osteoporotic bone weight bearing after trochanteric fracture fixation. The authors constructed a new implant based on the conventional condylar plate, as part of a stabile triangular system. Because of the special oblique form of the screw which absolutely stabilizes vertical and horizontal arm of the plate, this plate was named the transfixed condylar plate (TCP). Analysis showed 6 kN of tolerant loading elastic in TCP with a longer horizontal arm, while this value in the conventional condylar plate was 2...

BACKGROUND: Two types of implants used for the surgical fixation of extracapsular hip fractures are cephalocondylic intramedullary nails, which are inserted into the femoral canal proximally to distally across the fracture, and extramedullary implants (e.g. the sliding hip screw). OBJECTIVES: To compare cephalocondylic intramedullary nails with extramedullary implants for extracapsular hip fractures in adults. SEARCH STRATEGY: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (June 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2007, Issue 2), MEDLINE (1966 to June week 3 2007), EMBASE (1988 to 2007 Week 27), the UK National Research Register, orthopaedic journals, conference proceedings and reference lists of articles...

Subtrochanteric fractures are fraught with certain anatomic, biologic and biomechanical challenges. Evolution of implants like the Gamma nail, fixed-angle nail plates, compression hip screws and dynamic hip screws with trochanteric stabilization plates underlines a persistent quest for a better implant. We studied the dynamic condylar screw DCS as an implant on a series of 30 consecutive patients with subtrochanteric fractures. Our purpose was to assess this implant as a panacea for subtrochanteric fractures...

BACKGROUND: Cephalocondylic intramedullary nails, which are inserted proximally to distally (cephalocondylic), have been used for the surgical treatment of extracapsular hip fractures. OBJECTIVES: To compare all cephalocondylic intramedullary nails with extramedullary implants for the surgical treatment of extracapsular hip fractures in adults. This is the fourth substantive update of our original review which compared the Gamma nail with the sliding hip screw (SHS)...

The aim of the study was to evaluate the results of internal fixation with Dynamic Condylar Screw (DCS) in reverse oblique trochanteric fractures. In a two years period 238 patients with trochanteric fractures were treated in our department. In 31 cases (13%) the fracture has reverse obliquity (type II Evans). Internal fixation was performed with Ender nails (4 cases), AO condylar blade plate (11 cases), Dynamic Hip Screw (3 cases), Gamma nail (3 cases) and DCS (10 cases). Results 4 month after the surgery reveal that Gamma nail and DCS used in reverse oblique fractures were superior to other types of implants...

We compared the efficacy of the Medoff sliding plate (MSP) with 3 other screw-plate systems for fixation of unstable intertrochanteric fractures in a randomized multicenter trial of 569 elderly patients. The MSP has biaxial dynamic capacity along both the neck and the shaft of the femur unlike the other systems, which lack dynamic capacity along the shaft. 268 fractures were operated on with the MSP, and 301 with the dynamic hip screw (DHS), with or without a trochanteric stabilizing plate (DHS/TSP) or with the dynamic condylar screw (DCS)...

We tried to find the trauma mechanism and treatment rationale of ipsilateral concomitant hip and distal femoral fractures involving the articular surface. Between 1988 and 1995, 15 cases of ipsilateral hip (confined to neck or trochanteric areas of the femur) and distal (confined to supra- and intercondylar area of the femur) femoral articular fractures were collected. The hip fractures consisted of 10 trochanteric fractures and five neck fractures, which were managed with reduction and fixation in 14 (Knowles' pin in eight, DHS in four and standard Gamma nail in two), and primary bipolar hemiarthroplastry in one...

We compared the efficacy of a load-sharing device, the Medoff sliding plate (MSP), with that of 3 other load-bearing screw-plate devices for the fixation of subtrochanteric fractures in a randomized multicenter trial of 107 elderly patients. 55 fractures were operated on with the MSP, and 52 with the dynamic hip screw (DHS) with or without a trochanteric stabilizing plate (TSP) or with the dynamic condylar screw (DCS). The patient material in the groups was similar regarding age, domestic situation, preinjury walking ability and fracture types...

Sixteen cases of subtrochanteric femur fractures with greater trochanteric extension were treated using the AO dynamic condylar screw (DCS). 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. The overall union rate was 93.7% (15 of 16). One unique case of implant failure with varus nonunion was encountered following repeat trauma. The advantages of the implant and technique are a simplified procedure, shorter operative time, and rapid union...

The increasing incidence of trochanteric fractures renders their treatment a challenging task concerning both medical and increasingly socio-economical questions as well. The majority of these fractures occurs in elderly patients compromised by various preexisting medical problems. The primary goal of treatment therefore has to be early mobilisation to avoid secondary complications. This can only be achieved by operative treatment. Regarding the perioperative management an antibiotic as well as an antithrombotic prophylaxis is advisable...
