The present study reports a case of a 38-year-old man with a malignant lymphoma of the right clavicle who underwent reconstruction after a segmental resection of the clavicle. A hydroxyapatite prosthesis in the shape of the clavicle was placed across the defect in conjunction with Marlex mesh which entirely enveloped the prosthesis and iliac crest autogenous bone. The mesh also acted as a stabilizer to the segments. The postoperative management was not a burden to the patient. Postoperative radiographs indicated bony union to have been completed within six months of the operation. The patient returned to work as a driver eight months after surgery. The range of motion of the shoulder joint was not limited. The patient had no trouble in carrying out his daily life without pain. The appearance of the area operated was excellent. At the postoperative 39 months follow-up visit, a radiograph reconfirmed the stable reconstruction with a composite graft and bone bridging at the gap left in the prosthesis to have been maintained with little bone absorption. The results indicate a reconstruction using a Marlex mesh-enveloped composite graft consisting of a hydroxyapatite prosthesis and autogenous bone to be a useful alternative to other types of reconstruction for segmental clavicular defects.
