Limb Saving Surgery Without Endoprosthesis on Malignant Bone Tumors

Four cases of vascularized fibular graft and three cases of rotationplasty for reconstruction after wide resection in malignant bone tumors are presented. Since endoprosthetic reconstruction does not offer life-long durability and can cause limb discrepancy in growing patients dual vascularized fibular grafts should be considered for reconstruction of the diaphysis in the lower extremity. For reconstruction of the proximal humerus, the vascularized proximal fibula can be utilized, occasionally with the epiphyseal plate to minimize limb discrepancy in growing patients. Rotationplasty can be recommended because of good function even in lesions at the femoral diaphysis, neck, or proximal tibia.

Familial flexion-supination deformity at the PIP joint of the finger

The case of a 36-year-old female typist with familial bilateral flexion-supination deformity at the PIP joint of the long fingers is presented. This deformity was ascribed to hypoplasia of the radial lateral band and retaining structures of the long extensor tendon. The deformity was corrected by bridging the second dorsal interosseous muscle and the radial extensor lateral band with a free tendon graft and the reconstruction of retaining ligaments.
