Indications ' The T2 Humeral Nail is intended to provide temporary stabilization of various types of fractures, malunions and nonunions of the humerus. ' The nails are inserted using an opened or closed technique and can be static, dynamic and compression locked. ' The subject and predicate devices are indicated for use in the humerus. ' Types of fractures include, but not limited to fractures of the humeral shaft, non-unions, malalignments, pathological humeral fractures, and impending pathological fractures. Precautions Stryker Osteosynthesis systems have not been evaluated for safety and...

An X-Ray Template (1806-0003) is available for pre-operative planning. Thorough evaluation of pre-operative radiographs of the affected extremity is critical. Careful radiographic examination can help prevent intra-operative complications. If X-Rays show a very narrow intramedullary canal in the distal part of the humerus, retrograde humeral nailing is not possible. The proper nail length when inserted antegrade should extend from subchondral bone proximally, to 1cm above the olecranon fossa distally. The retrograde nail length is determined by measuring the distance from 1cm above the...

Operative Technique – Antegrade Technique Patient Positioning and Fracture Reduction The patient is placed in a semireclined “beach chair position” or supine on a radiolucent table. Patient positioning should be checked to ensure that imag­ ing and access to the entry site are possible without excessive manipulation of the affected extremity (Fig.  ). The 1 image intensifier is placed at the legside of the patient  the surgeon is positioned ; at the headside. Incision A small incision is made in line with the fibers of the deltoid muscle anterolateral to the acromion. The deltoid is split...

Operative Technique – Antegrade Technique Entry Point The entry point is made with the Curved, cannulated Awl (1806-0040) (Fig. 3). The 2.5 × 800mm Ball Tip Guide Wire (1806-0083S) is then introduced through the awl under image intensification into the metaphysis, central to the long axis of the humerus. Alternatively, the optional Crown Drill (1806-2020) may be used over the K-Wire with Washer (1806-0051S) for entry point preparation. The K-Wire will help to guide the Crown Drill centrally (Fig. 3a). Then, the 3 × 285mm K-Wire (18060050S) is introduced under image intensification into the...

Operative Technique – Antegrade Technique Unreamed Technique If an unreamed technique is preferred, the nail may be inserted over the 2.2 × 800mm Smooth Tip Guide Wire (1806-0093S) (Fig. 4). Reamed Technique For reamed techniques, the 2.5 × 800mm Ball Tip Guide Wire (1806-0083S) is inserted across the fracture site. The Reduction Rod (1806-0363) may be used as a fracture reduction tool to facilitate Guide Wire insertion across the fracture site (Fig. 5). Reaming is commenced in 0.5mm increments until cortical contact is appreciated. Final reaming should be 1mm−1.5mm larger than the diameter...

Note: • Humeral Nails cannot be inserted over the 2.5mm Ball Tip Guide Wire. The Ball Tip Guide Wire must be exchanged for the 2.2mm Smooth Tip Guide Wire prior to nail insertion. • Use the Teflon Tube (1806-0073S) for the Guide Wire exchange. When reaming is completed, the Teflon Tube (1806-0073S) should be used to exchange the Ball Tip Guide Wire (1806-0083S) with the Smooth Tip Guide Wire (1806-0093S) for nail insertion (Fig. 8 and 9). An unreamed technique can be considered in cases, where the medullary canal has the appropriate diameter. In these cases, the nail can be introduced over...

Operative Technique – Antegrade Technique Nail Selection Transverse Compression Slot (Oblique or Dynamic) Hole Positions The X-Ray Template should be used pre-operatively to determine the canal size radiographically. This information may be utilized in conjunction with the clinical assessment of canal size as determined by the size of the last reamer used. The diameter of the selected nail should be 1mm−1.5mm smaller than the last reamer used. Length End of Guide Wire Ruler is the measurement reference Fig. 11 Nail length may be determined with the X-Ray Ruler (Fig. 10). The Guide Wire...
