A consecutive series of 58 patients, treated with the dynamic condylar screw (DCS) for subtrochanteric fractures were retrospectively reviewed. A closed reduction should always be attempted. We routinely use the sliding-screw plating systems for intertrochanteric fractures. One might also use the articulated tension device if indicated. Which of the following factors has been shown to be the strongest predictor of screw cutout of a dynamic compression hip screw used for an intertrochanteric femur fracture? A patient with an intertrochanteric hip fracture undergoes reduction and dynamic hip screw application. The guide wire is advanced into the subchondral bone and its tip should lie 10 mm off the joint. Dynamic Hip Screw Compared to Condylar Blade Plate in the Treatment of Unstable Fragility Intertrochanteric Fractures May 2009 Malaysian Orthopaedic Journal 3(1):13-18 When treating a stable 2-part intertrochanteric hip fracture with a sliding hip screw construct, what is the minimum number of screw holes that are needed in the side plate for successful fixation?
Before 1999, 15 fractures were treated with a dynamic condylar screw (DCS) and after 1999, 11 fractures were treated with a gamma nail (GN). Related Links Articles in PubMed by Chung-Ho Pai; Articles in Google Scholar by Chung-Ho Pai; Other articles in this journal by Chung-Ho Pai; Related Videos. If the fracture pattern allows, additional cortical screws should be inserted into the proximal fragment to augment the fixation. Malunion was detected in 2 EPFN patients … Plate can break during use (when subjected to excessive forces). 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. The fixed angle between plate and barrel is 95° and the plate is contoured to fit the lateral surface of the distal end of the femur. All fractures united.

She was admitted to a local hospital for treatment. Technique guide are not considered high yield topics for orthopaedic standardized exams including the ABOS, EBOT and RC.
Patients with compound fractures. If unsuccessful, a limited open reduction is necessary. Compression of the fracture might be achieved if the cortical screws are inserted in a load position starting with the most distal screw. If at six weeks healing is progressing uneventfully, more loading might be allowed. Overall, seven patients (8.5%) went on to experience lag screw cut-out. Tested Concept QID: 3035 Type & Select Correct Answer. The mean age of all patients was 70 (31–92) years, and the mean follow up was 16 (9–30) months for the DCS group and 14 (6–26) months for the GN group. male gender (25-30% mortality) vs female (20% mortality), higher in intertrochanteric fracture (vs femoral neck fracture), 2 or more pre-existing medical conditions, co-management with medical hospitalists or geriatricians, useful if radiographs are negative but physical exam consistent with fracture, MRI useful to evaluate intertrochanteric extension with isolated greater trochanteric fracture patterns, preexisting symptomatic degenerative arthritis, osteoporotic bone that is unlikely to hold internal fixation, must obtain correct neck-shaft relationship, 4 hole plates show no benefit clinically or biomechanically over 2 hole plates, allows dynamic interfragmentary compression, can cause anterior spike malreduction in left-sided, unstable fractures due to screw torque, mismatch of the radius of curvature of the femur (shorter) and implant (longer), posterior starting point on the greater trochanter, Adult Knee Trauma Radiographic Evaluation, Proximal Humerus Fracture Malunion and Nonunion, Distal Radial Ulnar Joint (DRUJ) Injuries, roughly the same as femoral neck fractures, typically older age than patients with femoral neck fractures, proximal humerus fractures increase risk of hip fracture for 1 year, low energy falls in osteoporotic patients, intertrochanteric area exists between greater and lesser trochanters, vertical wall of dense bone that extends from posteromedial aspect of femoral shaft to posterior portion of femoral neck, helps determine stable versus unstable fracture patterns, Stability of fracture pattern is arguably the most reliable method of classification, will resist medial compressive loads once reduced, measured from 3 cm distal from innominate tubercle at 135 degrees to the fracture site, <20.5 mm suggests risk of postoperative lateral wall fracture, should be treated with intramedullary implant rather than sliding hip screw, fracture will collapse into varus and retroversion when loaded, fractures with a large posteromedial fragment, oblique fracture line extending from medial cortex both laterally and distally, patients at high risk for perioperative mortality, high rates of pneumonia, urinary tract infections, decubiti, and DVT, equal outcomes when compared to intramedullary hip screws for stable fracture patterns, 56% failure when treated with sliding hip screw, associated with increased displacement and collapse when treated with sliding hip screw, increased risk of lateral wall fracture with decreasing lateral wall thickness, use has significantly increased in last decade, short implants with optional distal locking, requires violation of hip abductors for insertion, must attempt fixation of greater trochanter to shaft, possible earlier return for full weight bearing, may require prosthesis that some surgeons are unfamiliar with, tip-apex distance >45 mm associated with 60% failure rate, can occur following intramedullary screw fixation, varus and rotational deformities are common. All of the following implants offer adequate fracture fixation of the injury shown in Figure A EXCEPT:
An 82-year-old female sustains an intertrochanteric hip fracture and is treated with a sliding hip screw.
Methods. Lateral approach between the vastus lateralis muscle and intermuscular septum. The dynamic condylar screw (DCS) is like the DHS in its design and concept. The decision is made to treat her with a trochanteric entry nail. Adjust the cannulated triple reamer to the chosen length of the screw.
Many implants have been used for operative treatment of these fractures, and most series report technical failures; we report the use of the AO dynamic condylar screw (DCS). A 67-year-old female falls and sustains the injuries shown in figures A and B. The follow-up period was from 6 to 15 months. Only if necessary, and then not before 18 months. The post-operative radiographs demonstrate that the lag screw is superior in the femoral head with a tip-apex distance of 40 millimeters. The selected screw is mounted on a handle and inserted over the guide wire.When the screw has reached its final position, the T-handle has to be in line with the longitudinal axis of the femur to guarantee that the plate will come to lie on the femoral shaft.Remove handle and leave guide wire in place. It Is The Blade Plate, You Just Don’t Know How To Do It!
internal fixation of an intertrochanteric fracture. To avoid bleeding, tie off the perforating vessels. ABSTRACT Background: Management of AO31A3 intertrochanteric fractures has unique problems because of pecu-liar anatomy, leading to high instability. The DCS plate does not allow for controlled collapse and compression.

It is done on a fracture table and subsequently, an appropriate fixation device is chosen. To overcome this problem, the 95° dynamic condylar screw (DCS) was introduced to stabilize this fracture pattern. There is no standard treatment protocol described in literature.
Take x-rays at six-week intervals. 95° Dynamic condylar screw (DCS) and proximal femoral nail (PFN) are currently the most commonly used implants for its fixation. 3,5,6 Though its use involves a relatively simple operative procedure, various modes of failure of DCS were observed in reverse oblique trochanteric fractures like cutting out of screw, breakage of the plate, and screw or plate pull off from the bone.
The post-operative radiographs demonstrate that the lag screw is superior in the femoral head with a tip-apex distance of 40 millimeters. This patient is at increased risk of what complication? Tested Concept, The use of intramedullary nail has increased in the last ten years, The use of sliding hip screws has increased in the last ten years, Medicare reimbursement is more for a sliding hip screw, Intramedullary nails have demonstrated superior outcomes in randomized-controlled studies, Sliding hip screw is superior for treatment of reverse obliquity intertrochanteric fractures, (OBQ09.222)
A 75-year-old male treated by a dynamic condylar screw-plate for a relatively long shaft extension of a reverse oblique fracture (31A3.3). DHS allows controlled collapse of the fracture followed by progressive stabilization. Setting: The study was conducted in Orthopaedic ward of Ghurki Trust Teaching Hospital/Lahore Medical & Dental College, Lahore. The guide wire is inserted through the aiming device. So, this prospective study was done to evaluate clinical outcomes of management of these fractures by Dynamic … Before 1999, 15 fractures were treated with a dynamic condylar screw (DCS) and after 1999, 11 fractures were treated with a gamma nail (GN). The plate is fixed to the femoral shaft with an appropriate number and size of plate holding cortical screws.If possible insert lag screw(s) through the plate to compress the fracture. 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. Which of the following deformities is most likely to occur with dynamic hip screw fixation of unstable left sided standard obliquity hip fractures? The study was conducted in order to find which method of surgical fixation has better functional outcome. Select a screw which is the same length as measured. Anterior perforation of the distal femur from antegrade femoral nailing has been attributed to what factor? The aim of the study was to examine the clinical outcome of fixing unstable intertrochanteric fractures using a newly designed 102° dynamic condylar screw (DCS). Two days later, a 135° dynamic hip screw and side plate were used to internally fix the fracture. 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. The aiming device for the DCS is chosen. Tested Concept, (OBQ07.246)
