dynamic condylar screw uses

Year: 2007. Mitkovic M, Bumbasirevic M, Golubovic Z, et al. Only stable proximal femoral fractures can be treated with the DCS (dynamic condylar screw) plate. This device has been studied and compared with cannulated screws and fixation with DHS showing inconclusive results. Fixation with compression should be applied when possible in fracture patterns where there is contact between the proximal and distal main fragments. Average follow-up was 3 years (range 14–65 months). Anatomical reduction of intermediate fragments is neither sought nor necessary.

Shortening is due to the pull of the quadriceps and hamstring muscles, while the varus and extension deformity is caused by the unopposed pull of the adductors and gastrocnemius, respectively. Access options Buy single article. The surgeon must take care not to use excessive stripping at this point to ensure adequate fracture healing. If a shaft fracture is multifragmentary, the image intensifier cannot be used to compare cortical diameters on each side of the fracture. This site uses cookies to improve your experience and to help show ads that are more relevant to your interests. To avoid this, the knee is brought into full extension, and the distal femoral fragment is stabilized in this position to the tibia. The TIBER™Dynamic Condylar Screw is designed to provide strong and stable fixation ofa variety certain distal femoral subtrochanteric fractures,with minimal soft tissue . OTHER INFORMATION The DHS plates and DCS plates are made of two materials – 1. Implant removal is not essential but should be discussed with the patient if there are implant-related symptoms after consolidated fracture healing. This axis can be checked intraoperatively by using a piece of cable, such as the diathermy cord. A radiographic ruler can be used to measure the length of both femora. Loosely secure the plate to the proximal femur with a Verbrugge clamp. Take care to restore the mechanical axis of the femur in all planes using the previously discussed techniques. An image intensifier or intraoperative radiography was used for the procedure. If the plate does not fit nicely against the side of the distal femur, then a chisel can be used to prepare a small channel for the DCS to recess into. US$ 39.95. Alternative: Some surgeons reconnect T-handle to the screw to help to adjust the position the plate. The muscle attachments to the distal femur are responsible for the typical displacement of the distal articular block following a supracondylar fracture, namely shortening with varus and extension deformity. Insertion of a Schanz pin from anterior to posterior in the distal femoral articular block, which can be used to correct hyperextension. Screw available holes: 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140 and 145. 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. [citation needed] It is the most commonly used implant for extracapsular fractures of the hip, which are common in older osteoporotic patients. Static cycling without load, as well as firm passive range of motion exercises of the knee, allow the patient to regain optimal range of motion. The early appearance of callus avoids the need for primary cancellous bone grafting, emphasising the importance of preserving biology of the fracture fragments. catastrophic in regards to a satisfactory fracture union and culminates in various complications.15 The distal femur has a unique anatomical shape. The ideal position of the DCS is shown by the yellow wire. The mechanism of injury was low-energy in 47 cases and high-energy in 11 cases. Pass a second guide wire over the anterior surface of the knee to indicate the plane of the patello-femoral condyles (green). Check the position of the guide wire carefully to ensure it has been correctly positioned, with the parallelism already described. Detach the T-handle and pass the plate barrel over the screw shank. Fractures of the distal femur and intercondylar fractures are the main indications. Few tricks in the technique make use of dynamic condylar screw in biological fixation of comminuted subtrochanteric fractures easier. This study was conducted to evaluate the results of fixation of this device in our Scenario . Attempts at a reduction of the intercondylar split with the pointed reduction forceps alone are often unsuccessful, as rotational control of the femoral condyle is also needed. 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. These screws must be countersunk and recessed beneath the articular surface. This will allow the plate to sit against distal femur. To ensure that femoral length has been restored, many options exist: Determine the correct position for the DCS with the help of guide wires around the joint. The guide wire for the DCS is positioned at 2 cm proximal to the distal end of femur. This … Thrombo-prophylaxis should be given according to local treatment guidelines. These screws may be fully threaded 2.7 or 3.5 mm lag screws (shown with gliding hole), 6.5mm partially threaded lag screws, or 4.0/4.5 mm cannulated, partially threaded lag screws. Next, slide the direct measuring device over the guide wire and determine guide-wire insertion depth and, thereby, the length of the DCS required. Direct manipulation of intermediate fragments would risk disturbing their blood supply. A 5.0 mm or 6.0 mm Schanz pin in the medial and/or lateral femoral condyle to act as a joystick. Five patients died before fracture healing. To review the results of indirect reduction and mini-incision dynamic condylar screw (DCS) fixation for comminuted subtrochanteric femoral fractures. The ideal entry point for the DCS is shown on the diagram. Cite . Fixation of a C1 fracture with the dynamic condylar screw system. Although this device was designed for use in the distal femur, it has features which make it attractive for use in subtrochanteric fractures. This illustration shows the longitudinal axes of the lower limb. Serial x-rays allow the surgeon to assess the healing of the fracture. Pitfall: It is important to remember that the distal femur tapers from the posterior to the anterior. In oblique, single-plane fractures, an interfragmentary lag screw should be inserted through the plate. Early range of motion helps restore movement in the early postoperative phase. Screws are inserted along the periphery of the articular surface of the lateral femoral condyle going from lateral to medial or from medial to lateral to compress the intercondylar split. Abstract We report our initial experience in Nottingham of use of the AO Dynamic Condylar Screw (DCS) implant system for internal fixation of fractures of the proximal and distal femur. Union was achieved in all cases (100%), with full-weight bearing after an average of 4.9 months. Use the impactor to bring the plate down to the bone, with the barrel sliding over the screw shank. Occasionally, a larger wedge fragment might be approximated to the main fragments with a lag screw. A bolster in the supracondylar region to reduce the hyperextension deformity of the distal femoral articular block. After assembling the DCS triple reamer and setting the reamer to the correct depth, ream the hole for the DCS over the guide wire. Even in multifragmentary fractures, there are usually a few main fracture segments that can assist the surgeon in ensuring that the appropriate length has been obtained. A line is drawn from the anterior aspect of the lateral femoral condyle to the anterior aspect of the medial femoral condyle (patellofemoral inclination) that slopes approximately 10°. This latter orientation ensures that the plate comes to lie flush with the lateral cortex. Florian Gebhard, Phil Kregor, Chris Oliver, Markku T Nousiainen. The dynamic condylar screw (DCS) is a new implant engineered by the AO/ASIF Group for use in management of proximal and distal femoral fractures. Tighten the articulated tension device with the spanner so that the indicator on the tension device is in the green zone, checking the fracture site carefully to ensure that no unwanted displacement occurs. Any fractures of the articular block are first addressed under direct vision using standard techniques of interfragmentary compression. In this illustration, internal rotation by 30° reveals that the guide wire length was chosen inappropriately. Pearl: Do not use the compression screw in osteoporotic patients – it can cause the DCS thread to strip out from the soft cancellous bone of the medial femoral condyle. A Schanz screw is inserted in the distal femoral articular block and used to counter the pull of the gastrocnemius. Reduction using axial traction on a fracture table was used in 24 cases , . If a fracture pattern can be reduced to a "simple" metaphyseal fracture pattern (such as an intact wedge fracture where the wedge is fixed to the main fragment), then compression can be used for the metaphyseal "simple" fracture. Impediments to the restoration of full knee function after distal femoral fracture are fibrosis and adhesion of injured soft tissues around the metaphyseal fracture zone, joint capsular scarring, intra-articular adhesions, and muscle weakness. Patients were assessed clinically and radiographically with regards to fracture classification, operating time, blood loss, time of union, malunion and other complications. Few tricks in the technique make use of dynamic condylar screw in biological fixation of comminuted subtrochanteric fractures easier. We use cookies to help provide and enhance our service and tailor content and ads. Emphasis should be placed on progressive quadriceps strengthening and straight leg raises. When reduced, a temporary cerclage wire is used to lock the position of the Schanz screw relative to the distractor. Insert a screw through the plate close to the compression device to secure the fixation. If a large fragment has separated from the fracture zone and impaled the adjacent muscle, direct reduction may be required. Another option involves taking radiographic images of the contralateral distal femur for comparison. 11. There was only one case of superficial infection, which settled with local debridement and antibiotics. Insert the proximal and distal fixator (distractor) pins carefully in order not to conflict with the later plating procedure. In conclusion, use of biological (indirect) reduction techniques instead of anatomic, open reduction has proven to be successful, especially in comminuted subtrochanteric fractures. The use of a dynamic condylar screw and biological reduction techniques for subtrochanteric femur fracture. If it appears to be outside the bone, it is most likely too long and the DCS will cause pain and possibly heterotopic ossification. Reduction aids that are helpful include: Before definitive fixation is undertaken, more than one foreceps is applied. Kulkarni SS, Moran CG. The Dynamic Condylar Screw is designed to provide strong and stable internal fixation of certain distal femoral and subtrochanteric fractures, with minimal soft tissue irritation. Reduction techniques. With stable fracture fixation, the surgeon and the physical therapy staff will design an individual program of progressive rehabilitation for each patient. When used in bridging mode, the plate is an internal fixator used as an extramedullary splint, fixed to the two main fragments, leaving the intermediate fracture zone untouched. However, this maneuver is not absolutely necessary, and some surgeons do not perform it. The radiological landmarks of the center of the femoral head, the center of the knee and the center of the ankle joint should all be in line if the mechanical axis of the femur is correct. A Schanz screw is inserted in the distal femoral articular block and used to counter the pull of the gastrocnemius. 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. Pearl: In osteoporotic bone, tapping should be omitted. Material and Methods. Insert the guide wire at the chosen entry site of the DCS. The preferred method depends on the fracture and soft-tissue injury pattern, the chosen stabilization device, and the experience and skills of the surgeon. The Dynamic Condylar Screw (DCS; Synthes, Bettlach, Switzerland) has been designed for the internal fixation of fractures of the distal and subtrochan- teric regions of the femur and has superior biomechanical properties compared to the blade plate [23–25]. There may be bleeding from the lateral genicular arteries, which will need to be controlled using diathermy. BibTex; Full citation; Publisher: Springer Science and Business Media LLC. 2.1. Alignment of the main shaft fragments can then be achieved indirectly, using various aids before application of the plate. Instant access to the full article PDF. New biological method of internal fixation of the femur. Due to the pull of the gastrocnemius muscle, the distal fragment tends to be displaced into extension at the metaphyseal fracture area, when distraction is applied. The cord is stretched from the iliac spine across the patella to the cleft between the first and second toes. Abstract Objective: To determine, by means of comparative biomechanical tests, whether greater compressive load resistance and flexion is presented by 95° angled blade plates or by dynamic condylar screws (DCS), and to correlate the failure type presented during the tests with each type of plate. When reduced, a temporary cerclage wire is used to lock the position of the Schanz screw relative to the distractor. Seen from an end-on view, the lateral surface has a 10° inclination from the vertical, while the medial surface has a 20–25° slope. MATERIAL AND METHODS This study was conducted in the Post- Graduate Department of Orthopaedics, Govt. The average operating time was 2 h and blood loss averaged 430 ml. This is a preview of subscription content, log in to check access. The patients were operated under spinal anaesthesia. The normal biomechanical axis follows a line from the center of the femoral head, through the center of the proximal tibia and then through the center of the ankle joint. Dynamic condylar screw has been found to be less technically demanding and provided good to excellent results as compared to other implants in treating patients with supracondylar and simple intracondylar fractures of the femur.3 Traditionally the DCS has been used by the open technique by exposing the fracture site. The dynamic condylar screw (DCS) was originally designed for use in fractures of the distal femur and intercondylar fractures, but has found increasing application in proximal femoral fractures, particularly subtrochanteric ones. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. 2. Strong. The dynamic condylar screw (DCS) is a new implant engineered by the AO/ASIF Group for use in management of proximal and distal femoral fractures. Ideally, patients are fully weight-bearing, without devices (e.g., cane) by 12 weeks. Malunion was seen in 2 cases out of 31 (6.4%) without the need for further surgery. Both active and passive motion of the knee and hip can be initiated immediately postoperatively. Once adequate alignment is achieved, insert a screw through the plate to secure the fixation. The DCS Plates are made of 316L stainless steel and are cold-worked for strength. Alignment of the main shaft fragments can be achieved indirectly with the use of: Mechanical stability, provided by the bridging plate, is adequate for gentle functional rehabilitation and results in satisfactory indirect healing (callus formation). The dynamic condylar screw in the management of subtrochanteric fractures: does judicious use of biological fixation enhance overall results? Touch-down weight-bearing progresses to full weight-bearing gradually, over a period of 2 to 3 weeks (beginning at 6–10 weeks postoperatively). Additionally, the compression screw will provide additional compression across any intraarticular split. This is mostly to protect the articular component of the injury, rather than the shaft injury. Fractures were classified according to the AO classification (10 type … If the mechanical axis is restored this should be adequate in most situations (fragmented patterns). This implant is particularly useful for obtaining metaphyseal compression. Touch-down weight-bearing (10-15 kg) may be performed immediately with crutches, or a walker. screws.15 Dynamic condylar screws (DCS) simplify fixation and require less-exacting technique than CBPs.16 We aimed to review the results of indirect reduction and mini-incision DCS fixation for comminuted subtrochanteric femoral fractures. It may not be used in situations of severe metaphyseal comminution and/or osteoporosis. The depth of guide-wire insertion is crucial. Some surgeons find it useful to use an external fixator (or femoral distractor) from the proximal femur to the proximal tibia. dynamic condylar screw-plates (DCS-Plates) on the distal femur. On the lateral view, the distal femur is divided into thirds and the DCS entry site is located at the junction of the anterior and middle thirds. Use of Schanz pins inserted into the medial, or lateral, femoral articular block to correct varus or valgus angulation of the femoral block. These anatomical details are important when inserting screws. Twenty-seven cases (87.2%) sustained these fractures either from traffic crashes or falls from height and the remaining four had a simple fall. Dynamic Condylar Screw used for fixation of: a, a subtrochanteric fracture, and b, a supracondylar fracture of the femur. For the plate barrel to slide over the screw, the T-handle should be parallel, on the lateral view, to the long axis of the distal fragment. It is very important to restore the biomechanical axis of the lower limb. Dynamic Condylar Screw is cost-effective and procedure relatively easy to perform and affords a rigid internal fixation. The aim of this study was to determine the amount of cortex loss in the distal femur when inserting a DCS-Plate. The DCS is a versatile plate which can be applied in a bridging mode (fragmentary supracondylar fracture component) and with compression (simple supracondylar fracture component). The regimens suggested here are for guidance only and not to be regarded as prescriptive. Wound healing should be assessed at two to three weeks postoperatively. Thirty-one consecutive patients with a mean age of 32.6 years, who sustained subtrochanteric femoral fractures, were treated with this method. slot cut for the blade determines the alignment of the plate with the shaft, no further adjustment being possible. In this technique, it is important that the x-ray beams are perpendicular to the OR table and that the ruler is parallel to the OR table. One option involves reducing the fracture fragments anatomically, either directly or indirectly with fluoroscopic control. Prior to plate fixation to the proximal fragment, final reduction of the metaphysis may be performed. Stable. This procedure may be performed with the patient in one of the following positions: For this procedure, the lateral/anterolateral approach is used. Secure the articulated tension device to the proximal femur with a bicortical screw. Tax calculation will be finalised during checkout. 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. This will be continued for 6-10 weeks postoperatively. It must be borne in mind that these structures can be damaged by the injury or can be damaged by the surgeon during the reconstruction. Dynamic Condylar Screw is cost-effective and procedure relatively easy to perform and affords a rigid internal fixation. A sand bag was used under the ipsilateral hemi pelvis. If rotation is correct, this cord will pass over the midline of the patella, and slightly medial to the tibial eminence. The two holes closest to the barrel accept 6.5 mm Cancellous Bone Screws. Courses, webinars, and online events, in your region or worldwide, Pediatric distal femur module is now online. The approach must adequately expose the articular surface of the distal femoral condyle. We have used dynamic condylar screw fixation to stabilize subtrochanteric fractures in our set –up. The use of a dynamic condylar screw and biological reduction techniques for subtrochanteric femur fracture. A consecutive series of 58 patients, treated with the dynamic condylar screw (DCS) for subtrochanteric fractures were retrospectively reviewed. https://doi.org/10.1016/S0020-1383(02)00319-4. Insert the guide wire under image intensifier control all the way across the femur. When the DCS is correctly inserted in the distal femur, the plate can be used to assist in the final reduction. The tip of the guide wire should just engage the medial cortex, and so will appear short of the medial condylar cortex on the AP intensifier image. Pointed reduction forceps, or large pelvic reduction clamps, to clamp from medial to lateral across the intercondylar split. Because of this, vascular injuries occur in about 3% and nerve injuries in about 1% of fractures of the distal femur. The use of the Schanz pin in conjunction with the pointed reduction forceps is therefore preferred. The dynamic condylar screw (DCS) is like the DHS in its design and concept. Copyright © 2021 Elsevier B.V. or its licensors or contributors. In order to assess the exact length of the guidewire obtain an AP view with 30° internal rotation of the lower extremity. The Dynamic Condylar Screw is designed to provide strong and stable internal fixation of certain distal femoral and subtrochanteric fractures, with minimal soft tissue irritation. Methods. Copyright © 2003 Elsevier Science Ltd. All rights reserved. The plate of the dynamic condylar screw was contoured in harmony with the flare of the trochanter as per the pre-operative planning. A cancellous screw can then be inserted into the most distal screw hole of the plate to prevent rotation of the distal femoral articular block around the axis of the DCS. Dynamic Condylar Screw Fixation for Comminuted Proximal Femur Fractures Fig II: Same fracture two months postoperative after fixation with dynamic condylar screw construct.
