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. 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. Management Of Subtrochanteric Femoral Fractures By Dynamic Condylar Screw (DCS) 2 of 6 Patients with pathological fractures. Considering the technical aspects of the osteosynthesis of these fractures, in our department, we staged the procedure one week apart. Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct. To avoid bleeding, tie off the perforating vessels. Ten out of 11 young patients, (nine with high-energy injuries), united primarily. Reverse oblique trochanteric fracture of femur is a distinct fracture pattern. The fascia lata is incised in line with the skin incision and in line with its fibers. This should be controlled under image intensification.The second step is internal rotation of the leg. 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 … It is placed against the lateral cortex. Which of the following is not an appropriate implant for treatment of the fracture seen in Figure A? Compression of the fracture might be achieved if the cortical screws are inserted in a load position starting with the most distal screw. The Lost Art With Better Success - Michael J. Gardner, MD (OSET 2018), Question Session | Intertrochanteric Fractures & Legg-Calve-Perthes Disease, Unstable Intertrochanteric Hip Fracture in a 72M. Tested Concept, Intraoperative fracture of the lateral femoral wall, (OBQ06.157) A 55-year-old male is involved in a motor vehicle accident and sustains the injury seen in Figure A. To overcome this problem, the 95° dynamic condylar screw (DCS) was introduced to stabilize this fracture pattern. In the AP view it should be in the lower or caudal half of the femoral head. The post-operative radiographs demonstrate that the lag screw is superior in the femoral head with a tip-apex distance of 40 millimeters. 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 To evaluate the success of dynamic condylar screw (DCS) fixation for comminuted proximal fractures of femur in adults. (OBQ16.168) 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. Drill the hole for the screw and the plate sleeve. April 2020; DOI: 10.18410/jebmh/2020/152. Overall, seven patients (8.5%) went on to experience lag screw cut-out. DHS allows controlled collapse of the fracture followed by progressive stabilization. A consecutive series of 58 patients, treated with the dynamic condylar screw (DCS) for subtrochanteric fractures were retrospectively reviewed. There were 46 intertrochanteric (IT) hip fractures and 36 subtrochanteric (ST) fractures. The follow-up period was from 6 to 15 months. All of the following implants offer adequate fracture fixation of the injury shown in Figure A EXCEPT: 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 dynamic condylar screw (DCS) is like the DHS in its design and concept. Again it has to be checked under image intensification in 2 planes as the reduction determines the degree of internal rotation. Twelve unstable low-energy intertrochanteric fractures were fixed using 102° DCS. He has Type 2 diabetes mellitus, atrial fibrillation, coronary artery disease, end-stage renal disease on dialysis and chronic obstructive lung disease. She was admitted to a local hospital for treatment. 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). Methods. 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) The decision is made to treat her with a trochanteric entry nail. In fresh cases, a traction table might not be necessary and the procedure can be done with the patient positioned on a translucent table designed for use with image intensification. What is the most appropriate definitive step in treating the failure seen in figure A? We routinely use the sliding-screw plating systems for intertrochanteric fractures. Tested Concept QID: 3035 Type & Select Correct Answer. The aiming device for the DCS is chosen. Setting: The study was conducted in Orthopaedic ward of Ghurki Trust Teaching Hospital/Lahore Medical & Dental College, Lahore. Tested Concept, (OBQ05.210) In most instances it will be an intramedullary device. The mechanism of injury was low-energy in 47 cases and high-energy in 11 cases. Only stable proximal femoral fractures can be treated with the DCS (dynamic condylar screw) plate. The study was conducted in order to find which method of surgical fixation has better functional outcome. The mean time to union was 16 (range, 13-22) weeks. Tested Concept, American Society of Anesthesiologist (ASA) classification, (OBQ05.262) A 74-year-old female falls from a standing height and sustains the fracture shown in Figure A. The patient was permitted full weight bearing 2 months after operation. A 67-year-old female falls and sustains the injuries shown in figures A and B. If necessary use a small Hohmann in order to visualize the bone.A pointed reduction clamp is used to reduce the fracture and maintain reduction. (OBQ09.222) A patient with an intertrochanteric hip fracture undergoes reduction and dynamic hip screw application. Tested Concept, Trochanteric entry point cephalomedullary nail, Piriformis fossa entry point cephalomedullary nail, (OBQ05.161) MortalityMortality generally occurs within the first six months after fracture; studies have shown that these rates range from 12-37%.Predictors of higher mortality rates are patients who are: For more information see the additional material on perioperative care in elderly hip fracture patients. Twelve unstable low-energy intertrochanteric fractures were fixed using 102° DCS. All fractures united. On the axial view it should be parallel to the axis of the neck and in the middle of the neck. However, there are divergent opinions about the fixation of unstable intertrochanteric fractures in the elderly. In osteoporotic bone, five screws (10 cortices) are advised.The DCS plate is now inserted and seated with the impactor. Exclusion Criteria were: Skeletally immature patients. Patients with compound fractures. 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.
