Allografts with autogenous platelet-rich plasma for tibial defect reconstruction: a rabbit study. (1/24)

PURPOSE: To evaluate the effect of autogenous platelet-rich plasma (PRP) for fresh-frozen allografts in tibial defect reconstruction in rabbits. METHODS: 40 adult New Zealand white rabbits underwent tibial defect reconstruction with autografts (n=12), allografts without PRP (n=12), or allografts with PRP (n=12) and were observed for 12, 16, and 24 weeks (4 for each period). Tibias of the remaining 4 rabbits were used as donor allografts, and the remaining allografts were procured from recipient rabbits. A 1.5- cm cortical segment of the tibia was osteotomised, and then fixed with a 9-hole mini-compression plate and 2 cerclage wires. Allografts were stripped off the periosteum and soft tissues and medullary contents, and then stored in a freezer at -80 masculineC. All allografts were deep frozen for at least 4 weeks before transplantation. 7 ml of whole blood was drawn to prepare 1 ml of PRP. The PRP was then mixed with 1.0 ml of human thrombin to form a platelet gel. The PRP gel was then packed into the medullary canal of the allograft and applied on the cortical surface before tibial defect reconstruction. Rabbits were sacrificed at 12, 16, and 24 weeks. The specimens were assessed for bone union at host-graft junctions and for bone resorption, new bone formation, callus encasement, and viable osteocyte counts. RESULTS: There were 4 specimens in each group at each observation period. Osteoid bridging the gap at host-graft junctions was noted in all specimens in the autograft and allograft-with-PRP groups at week 12 and in the allograft-without-PRP group at week 24. Bone union in allografts without PRP was delayed. All indices for biological incorporation (resorption index, new bone formation index, callus encasement index, and viable osteocyte count) were significantly greater in the autograft than allograft-without-PRP groups, except for the resorption index at week 24, whereas the differences were not significant between the autograft and allograft-with-PRP groups. The differences between the 2 allograft groups were usually not significant, except for the resorption index. CONCLUSION: PRP-augmented allografts behaved similarly to autografts for tibial defect reconstruction in rabbits. PRP increased bone union and bone resorption. (+info)

Distal fibular lengthening after premature growth arrest: a case report. (2/24)

Post-traumatic premature closure of the distal fibular growth plate is a rare entity leading to shortening of the lateral malleolus. We report on a 14-year old boy who presented with a 4-year history of worsening, diffuse discomfort and swelling of his left ankle, as well as fibular shortening and talar malreduction. He had sustained a distal tibial fracture 4 years earlier and had been treated with closed reduction. He reported instability of the ankle and difficulty with running. There was 1-cm shortening of the left fibula, 1-cm shortening of the proximal fibula, and slight widening of the medial clear space. Both tibial and fibular growth plates were already closed and the left ankle joint space was slightly narrowed. He was treated with late fibular lengthening and autogenous iliac crest tricortical bone grafting and achieved anatomic restoration of the distal tibiofibular relationship. At one-year follow-up, the ankle-hindfoot score had improved from 69 to 100. (+info)
