Reconstruction of the iliac bone using the homolateral femur after resection for pelvic tumor

AbstractThe authors have treated three patients with extensive involvement of the acetabular and peri-acetabular bone by a malignant tumour. One had a metastasis from a carcinoma of the thyroid, one from a carcinoma of the breast and one a plasmacytoma. In all three cases, the upper part of the femur was unaffected. It was used to replace the resected pelvic bone and fixed to the remaining bone by screws and plates. An acetabular cup was cemented into the transplanted bone, which itself was replaced by a massive femoral prosthesis. This technique allowed the patients to resume weight bearing rapidly. Two patients were alive and walked satisfactorily after two and four years respectively. The third died five months after the surgical procedure

Locked nailing for the treatment of displaced articular fractures of the calcaneus: description of a new procedure with calcanail®

Although open reduction and internal fixation is considered the best method for treating displaced articular fractures of the calcaneus, lateral approach is at high risk for wound healing complications. For this reason, the authors developed a posterior approach and a new implant to perform both intrafocal reduction and internal fixation. The aim of this technical note is to describe this method of treatment for displaced articular fractures of the calcaneus, which offered the following advantages: (a) the creation of a working channel that provides also a significant bone autograft, (b) the intrafocal reduction of the displaced articular surface, (c) the insertion of a locking nail that maintains the reduced articular surface at the right height, (d) the possibility to switch from an ORIF to a reconstruction arthrodesis with the same approach and instrumentation in case of severely damaged posterior facet
