Donor site reconstruction in iliac crest tricortical bone graft: surgical technique.

Background And Purpose: Autogenous bone grafts from the iliac crest are frequently harvested for autologous bone transplantation, because this is still the gold standard in the treatment of many bone defects. However, significant donor site morbidity must be considered. We have developed a simple method to treat the bone defect in the donor site in order to reduce some of the morbidity.

Avascular necrosis of distal tibial epiphysis: report of two cases.

Unlabelled: The authors present two cases of necrosis of the distal tibial epiphysis without evidence of trauma in either of the patients. One patient after a long follow-up showed a Charcot arthropathy. In contrast, the second patient recovered distal epiphysis ad integrum.

Fibular rotational osteotomy for the treatment of distal tibial osteochondroma: a technical modification for deformity correction and improved outcomes.

The technique of choice for excision of osteochondromas located in the lateral aspect of the tibia is a transfibular approach to expose the lesion for resection. A drawback of this approach is that removal of the lesion leaves a void that may cause a visible deformity and adversely affect long-term function. Fibular rotational osteotomy followed by fibular graft may minimize the resultant deformity, producing a more satisfactory functional and cosmetic result.

The in vivo performance of a sol-gel glass and a glass-ceramic in the treatment of limited bone defects.

The in vivo evaluation, in New Zealand rabbits, of a SiO(2)-P(2)O(5)-CaO sol-gel glass and a SiO(2)-P(2)O(5)-CaO-MgO glass-ceramic, both bioactive in Kokubo's simulated body fluid (SBF), is presented. Bone defects, performed in the lateral aspect of distal right femoral epiphysis, 5mm in diameter and 4mm in depth, were filled with (i) sol-gel glass disks, (ii) glass-ceramic disks, or (iii) no material (control group). Each group included 8 mature and 8 immature rabbits.
