0x6.001.024_AA 13.10.09 10:05 Seite 3 Aiming arm can be used as elongation for insertion handle when turned 180° away from the plate Submuscular insertion and percutaneous fixation The LCP Percutaneous Aiming System 3.5 for PHILOS facilitates submuscular insertion and percutaneous fixation of PHILOS via the transdeltoid approach. The design of the LCP Percutaneous Aiming System 3.5 for PHILOS is opti- mized to reduce the risk of interfering with the axillary nerve during screw insertion. To protect the axillary nerve, screw levels C to F are blocked. Screw holes in these sections cannot be...

0x6.001.024_AA 13.10.09 10:05 Seite 4 AO Principles In 1958, the AO formulated four basic principles, which have become the guidelines for internal fixation.1, 2 Those principles as applied to the LCP Percutaneous Aiming System 3.5 for PHILOS are: Anatomic reduction The precontoured plate facilitates restoration of the humeral head and the reduction of the metaphyseal segments to the diaphysis. Stable fixation Locking screws with optimized angles create a fixed-angle construct, providing angular stability. Preservation of blood supply The LCP Percutaneous Aiming System for PHILOS simplifies...

0x6.001.024_AA 13.10.09 10:05 Seite 5 Patient Positioning and Approach 1 Position the patient Place the patient in the beach chair position on a radiolucent table. A lateral side table is recommended to place the abducted arm and to relax the deltoideus muscle. Ensure the fluoroscope is positioned in a way that allows visualization of the proximal humerus in two axes (AP and lateral/axial). Prepare the patient’s arm so that it can be mobilized intraoperatively. 2 Approach Perform a transdeltoid approach. Begin the incision at the anterolateral tip of the acromion and extend it approximately...

0x6.001.024_AA 13.10.09 10:05 Seite 6 Implantation 1 Reduce fracture and fix temporarily Proper reduction of the fracture is crucial for good bone healing and function. In some cases, closed reduction before prepping the patient is beneficial. Reduce the head fragments and check the reduction using image intensifier control. Kirschner wires can be used for reduction as joysticks in the fragments and for temporary fixation. Ensure that the Kirschner wires do not interfere with correct plate placement. Note: The locking screws are not suitable for reduction since they cannot exert...

0x6.001.024_AA 13.10.09 10:05 Seite 7 2 Prepare plate position Note: The LCP Percutaneous Aiming System 3.5 for PHILOS is used with the PHILOS plate. Please consult the surgical technique guide “Philos and Philos long” (036.000.166) for detailed information on the implant and its indications. For optimal plate positioning, insert two positioning Kirschner wires 2 mm – 4 mm lateral to the bicipital groove and 5 mm – 7 mm below the tip of the greater tubercule. Note: Placing the plate too high increases the risk of subacromial impingement. 2a Alternative technique Instrument 03.122.006 or...

0x6.001.024_AA 13.10.09 10:05 Seite 9 4 Insert plate Slide the plate into the subdeltoid space and along the bone. Always keep the plate in contact with bone. Warning: Do not injure the axillary nerve. The axillary nerve can be palpated at the lower margin of the incision. Note: Do not use the insertion handle and the plate for soft tissue retraction or for release or dissection of the deltoid insertion. Synthes 9
