title: Reconstruction by Grosse-Kempf nailing in resections for bone tumor.
abstract: The authors report 38 reconstruction by Grosse-Kempf nailing for resection of bone tumor; there were: intercalar resections: 16; arthrodeses of the knee: 13; arthrodesis of the ankle joint: 5; gyroplasty: 4. Massive homoplastic bone graft was used in 26 cases, in 3 of which autoplastic grafting was associated; autoplastic grafts were used exclusively in 7 cases, and a cement spacer was used in 1. Twenty-nine patients (76%) obtained satisfactory final results, but in 10 cases secondary surgery was performed for a total of 14 operations, of which 7 major (1 nail substitution and 6 vascularized fibula operations). There were 7 failures: mechanical complications: 6; infection: 1. The highest number of non-unions were observed where massive homoplastic grafting was used: intercalar reconstruction: 11; arthrodesis of the knee: 7. The results were evidently better and the incidence of complications low in cases in which autoplastic grafting was used or where gyroplasty was performed. Absolute stiffness and best possible contact are difficult to obtain with blocked intramedullary nailing. On the contrary, when autoplastic grafts are used or when gyroplasty is performed micromovements allowed the instrumentation are compatible with good consolidation.
