HAMMERTOE IMPLANT S WANS O N hammertoe IMPLANT general PRECAUTIONS as described by Lowell Scott Weil, DPM The potential for complications or adverse reactions with any implant can be minimized by following the instructions for use provided in product literature. It is the responsibility of each surgeon using implants to consider the clinical and medical status of each patient and to be knowledgeable about all aspects of implant procedure and the potential complications that may occur. The benefits derived from implant surgery may not meet the patient’s expectations or may deteriorate with...

HAMMERTOE IMPLANT Some preventive measures to consider to minimize the potential for complications: • Follow guidelines for indications and contraindications provided below: • Identify prior pathology • Stabilize collapse deformities • Bone graft pre-existing cysts • Use a properly sized implant • Avoid K-wires and sutures through the implant If complications develop, possible corrective procedures include: Implant removal • Implant removal • Synovectomy • Bone grafting of cysts • Limited intertarsal fusion • Replacement of the implant • Removal of the implant with fusion of the joint...

HAMMERTOE IMPLANT Some degree of particle formation is inevitable with all implants including those made of silicone elastomer. The amount will vary with factors such as patient activity, metatarsal stability or instability postimplantation, implant position and the amount of soft tissue support. The patient’s biological response to these particles is variable, but can include local synovitis and bone lysis in contiguous bones. Another potential concern with silicone implants arises from case reports in the literature suggesting an association between silicone implants and immunological...

HAMMERTOE IMPLANT deformities, or recurrence of the original deformity. In addition, the possible complications of arthrodesis (e.g., poor positioning, incomplete fusion, etc.) as well as the postoperative fixation required for arthrodesis are minimized. A sizing set, supplied nonsterile and not suitable for implantation, is available for proper size determination during surgery. An instrument set which includes a hand reamer and a hand compactor is also available in two sizes. The reamer is used to drill the medullary canal, while the compactor is used to shape the canal to match the stem...

HAMMERTOE IMPLANT BONE PREPARATION Proper preparation of bone is very important. Bone size is small and care should be taken if power equipment is to be used. To prepare intramedullary canals for implant, the head of the proximal phalanx is resected approximately 7 to 8mm from its distal aspect. Using a wire, drill or preferably a small size Swanson Intramedullary Broach (Cat. #6480-0100) a centered, pilot hole is made by rotating the instrument into the proximal phalanx, followed by use of the Size 1 Compactor (Cat.#5431-0110) is used to compact the medullary canal and allow for an exact...
