Variable Angle LCP Dorsal Distal Radius Plate 2.4. For fragment-specific fracture fixation with variable angle locking technology. The low profile dorsal distal radius plates are intended for the double-­ plate technique. All implants are available in stainless steel and titanium. Variable angle locking Holes allow up to 15° off-axis screw a ­ ngulation in all directions in order to a ­ ddress the individual fracture patterns. Undercuts and bending notches Undercuts and bending notches a ­ llow easy contouring of the plates while preserving the VA locking holes. Low profile construct Rounded...

Intended Use The plate and screw implants included in the Radius Plate product family are intended for temporary fixation, correction or stabilization in the radius anatomical region. Indications 2.4 mm Variable Angle LCP Dorsal Distal Radius Plates are ­indicated for: –– Dorsally displaced fractures –– Extra-articular and intra-articular fractures with ­metaphyseal defect –– Open joint reconstruction –– Combination of distal radius with carpal and metacarpal fractures –– Corrective osteotomies after distal radius malunion Variable Angle LCP Dorsal Distal Radius Plate 2.4  Surgical Techniqu

Three-Column Theory The treatment of distal radius fractures requires a meticulous reconstruction of the joint surface, as well as stable internal fixation and early functional postoperative treatment. Extra-articular fractures require both the restoration of the volar tilt and radial length to reduce the possibility of displacement. Any malalignment may result in limitations of movement, changes of load distribution, mid-carpal instability as well as the increased risk of osteoarthritis in the radiocarpal joint. Intra-articular fractures with articular displacement of more than 2 mm in the radiocarpal...

Recommendations on Screw and Plate Insertion Screw Insertion Techniques Variable angle locking screws can be inserted using two different techniques: – Variable angle technique – Pre-defined nominal angle technique Funnel-shaped end for offaxis drilling Fixed-angle end for nominal angle drilling VA-LCP Drill Sleeve (03.110.000) VA-LCP Drill Sleeve, freehand (03.111.004), for off-axis drilling a) Variable angle technique To drill variable angle holes up to 15° deviation from the nominal trajectory of the locking hole, insert the tip of the VA-LCP drill sleeve and key into the cloverleaf design...

Recommendations on Screw and Plate Insertion Screw Type Determination Determine whether standard cortex screws or variable angle locking screws will be used for fixation. The final screw placement and the use of VA locking and cortex screws are determined by the fracture pattern. If a VA locking screw is inserted first, ensure that the plate is held securely against the bone to prevent the plate from spinning as the screw locks into the plate. When using the pre-defined nominal angle technique s ­ tandard locking screws can also be used instead of VA ­locking screws. VA locking hole: 2.4 mm VA...

Recommendations on Screw and Plate Insertion Plate Insertion Technique 1. Apply dorso-ulnar plate It is recommended to apply the dorso-ulnar plate first and fix it by inserting a 2.4 mm standard cortex screw in the o ­ blong VA combi-hole in the proximal shaft. (See pages 16 –17 for insertion of cortex screws.) The plate supports the intermediate column and fixes the dorso-ulnar fragment. 2. Apply dorso-radial plate Apply the dorso-radial plate after provisional positioning of the dorso-ulnar plate by inserting a 2.4 mm standard cortex screw in the oblong VA combi-hole in the proximal shaft....
