CAUTION: Federal Law (USA) restricts this device to sale by or on the order of a board certified physician. WARNING: If there is no sufficient bone healing, wrong or incomplete postoperative care, plate might break. All ITS plates are preformed anatomically as a matter of principle. If adjustment of the plate to the shape of the bone is required, this is possible by carefully bending gently in one direction once. Particular care is required when bending in the region of a plate hole, as deformation of the plate may lead to a failure of the locking mechanism. The plate must not be buckled or...

Preface The development of the PROlock Radius Locking Plate 2.0 is based on the excellent results of the previous ITS. Radius Plates. Minimization of flexor tendon irritation due to the anatomical plate design and rounded edges. Precise and rapid screw placement of the distal plate holes with predefined angles using the radiolucent drill guide. The special feature of this implant is the free choice of screw placement. The user is able to set any desired screw in any hole (except oblong hole).

Indications, Contraindications & Time of operation Indications: • Complex intra- & extra-articular fractures of the distal radius with comminuted zone • Corrective osteotomy of the distal radius Contraindications: • Very advanced osteoporosis with soft bones • Disintegration of the radius-joint surfaces to the extent that there is no support for screws • Obesity • Lack of patient compliance Time of operation: • Acute, on the day of the accident • After swelling has subsided (5-10 days) • In the case of additional questions concerning the wrist surface, a CT scan can be performed.

Access The skin incision is performed on the distal forearm volar, above the tendon of the flexor carpi radialis and reaching to the crease of the wrist (FCR-approach). Split the deep fascia of the forearm. Release the pronator quadratus muscle from the distal radius beginning at the radial edge. Implantation Suspending the thumb with a counterpoise, the fracture is loosened and the length restored. The individual fragments are reduced with the appropriate instrumentation, and, if necessary, the comminuted zones are filled with bone substitute to achieve a provisional reduction in position...

Possible temporary fixation of individual fragments using a guide wire, steel, D=1.6mm, L=150mm, TR w. Thrd. (35164-150) - check reduction under fluoroscopy. After anatomical reduction is achieved, the implant is chosen and, if required, its contour can be modified. First, fill the oblong hole with a D=2.7mm cortical screw (32271-XX) (suitable drills see page 6). Check the reduction and position of the plate under fluoroscopy.

 Open the catalog to page 14

Due to the oblong hole it is possible to adjust the plate position either distal or proximal.

 Open the catalog to page 15

For temporary fixation of the fragments there are 3 distal K-wire holes.

 Open the catalog to page 16

Next fill the shaft holes with either D=3.0mm cortical stabilization screws (37304-XX) or with D=2.7mm cortical screws (32271-XX) (suitable drills see page 6).

 Open the catalog to page 17

After re-checking the reduction 4 or more D=2.4mm stabilization screws (37241-XX) or D=3.0mm cancellous stabilization screws (37303-XX) should be used for the relevant fragments (suitable drills see page 6). Pay attention that the distal locking screws are placed as closely to the wrist surface as possible in order to take advantage of the hard subchondral bone. Two rows of screws are recommended to provide optimal support to the articular surface especially if only the D=2.4mm stabilization screw is used. Final check under fluoroscopy.
