 Open the catalog to page 1

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 newly developed Proximal Humeral Locking Plate enables the medical treatment of fractures in the joint area with an optional less invasive method. 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). Especially with complex fractures the free choice of screw angle (+/- 15°, see page 21) has advantages in the fracture treatment.

Assembling of the percutaneous guide 1 Pre-operative patient preparation • Positioning on a radiolucent surgical table • Semi-sitting angle of about 30° - 40°, shoulder should be freely moveable (optional shoulder table) • The arm should be freely moveable to allow fracture reduction • General anaesthesia, regional anaesthesia or combination can be u

Exposure Anterolateral access: • Skin incision parallel to the anterior acromion and extension 5cm distally in fiber direction of the M. deltoideus. • Detachment of the pars acromialis of the M. deltoideus. Reduction Anatomical reduction of the fracture under fluoroscopy.

Plate insertion • • • • Insert the plate, assembled on the percutaneous guide (recommended in Z position) Plate remains in constant contact with the bone and slide distally Align the proximal end of the plate on the Tuberculum majus Verify the correct plate position. Optional temporary fixation with guide wires, steel, D=1.6mm, L=260mm, TR, w. thread (35164-260) into proximal guide wire h

Intraoperative identification of screw length 1. Insert the depth gauge for humeral systems (59222) after drilling screw holes. Then, hook into the far medial cortices and read off the required screw length. 2. Drill screw holes under fluoroscopy guidance through the far medial cortices. Then, read off the required screw length at the calibrated spiral drill D=2.7mm, L=220mm (61273-220). Note: In the proximal area, the screw length is determined using the depth gauge, solid small fragment screws (59022).

Placement of the screws Fix the plate temporarily to the bone and drill with the spiral drill, D=2.7mm, L=220mm, AO Connector (61273-220) in the oblong hole. Drilling is performed through the D=2.8mm drill sleeve (118005-10) that was placed in the tissue protection sleeve (118005-8). Then, the drill sleeve is removed and a D=3.5mm cortical screw (32351-XX) (appropriate length measured before) is inserted through the tissue protection sleeve. Advice: For optimal positioning and adjustment of the humeral length, we recommend to first fill the oblong hole. Therefore there is a centric and...

Unscrew the clamping nut (118005-4) up to the black mark (see picture below), rotate the handle 180° and tighten the clamping nut by hand. Then using the spiral drill, D=2.5/2.7mm, L=220mm, AO Connector (61253-220/61273-220) to drill through the drill guide, D=2.7/2.0mm (62202) into a proximal hole. Use the screwdriver, WS 2.5 (56252-150) to insert a D=3.5mm locking cortical screw (37351XX-N) or a D=4.2mm locking cancellous screw (37422-XX-N) of appropriate length determined previously with the depth gauge, solid small fragment screws (59022).
