Synthetic Hydroxyapatite

Autogenous bone grafting has been the standard approach to reconstruction of trauma-induced metatarsal defects. However, this treatment has well-known disadvantages related to the harvesting, size, shape, and availability of autografts. The authors used a synthetic hydroxyapatite bone-graft substitute manufactured from a marine coral with a morphology similar to that of cancellous bone in the reconstruction of a large, post-traumatic first metatarsal defect. The authors found grafting with coralline hydroxyapatite to be a safe and effective substitute for autogenous bone grafting in the post-traumatic setting.

Autogenous Bone Grafting

Autogenous bone grafting is an important part of many foot and ankle surgical procedures. Although alternative bone graft materials such as allogeneic bone are available, autogenous bone continues to be the material of choice for many procedures. The calcaneus provides a source of small amounts of autogenous corticocancellous or cancellous bone. The author describes the surgical technique for procurement of calcaneal bone grafts. Twenty-five cases are reviewed. The morbidity associated with procuring calcaneal bone grafts is favorably compared with that associated with procuring bone from other donor sites.

Background and Aims: Ceramic bone graft substitutes have a potential to be used as replacement of allogeneic bone grafting and, under optimal distribution of particle size, they may even provide mechanical support. The current study examined the efficacy of bioactive glass granules as an extender of autogenous bone grafting in a segmental bone replacement model of the canine femur. Material and Method: A 16 mm long segment of the femur shaft was bilaterally replaced with an intercalary titanium implant in eight animals. The implant had cementless grooved proximal and distal stems. In one leg, the peri-implant space was packed with composite graft consisting of a mixture of bioactive glass granules and autogenous bone graft in proportion of 50:50. In the opposite leg, the peri-implant space was treated with autogenous bone graft alone. After surgery, unlimited functional loading was allowed. The outcome was evaluated at three months. Results: Eight out of sixteen autografted implants and seven out of sixteen composite-grafted implants were radiographically incorporated and clinically stable at three months. In the paired comparison, the proximal components of composite-grafted implants showed lower maximum load under torsional testing (p=0.068), less new bone in the longitudinal grooves of the stems (p=0.036) and lower affinity of new bone to implant surface (p=0.046). The distal components of the two sides showed a similar trend for less new bone in the grooves and lower bone affinity of new bone in the distal composite-grafted components. Conclusions: The current study suggests that supplementation of periprosthetic bone graft with bioactive ceramic particles may not help to promote healing of cementless implants under high dynamic loading conditions.

Second Toe

The author presents a case report with a 1-year follow-up period demonstrating successful bone graft stabilization of an iatrogenic flail second toe. The author discusses the techniques for calcaneal autogenous bone grafting for reconstruction of the iatrogenic shortened toe combined with ancillary procedures to improve the digital length pattern. After 18 months, this staged approach to stabilization of the digit and realignment of the digital length pattern appears to be successful.

Delayed Implant Placement

In the case of multiple hopeless teeth and severe bone loss, a conventional healing protocol of 3–4 months has been recommended to prevent the possibility of infection or unpredictable resorption of grafted bone during consolidation of the extraction socket. The use of a provisional denture is inevitable in the case of delayed implant placement, which is a common risk factor for wound dehiscence after a bone graft. Although autogenous bone is still the gold standard for bone grafting because of its excellent biocompatibility and osteogenic potential, there has been controversy in the unpredictable resorption of autogenous bone grafting. We present a case of successful maxillary rehabilitation without the use of provisional dentures by immediate implant placement, with early loading accompanying an extensive autogenous bone graft.

SummaryCancellous bone grafting is a widely accepted technique in human and veterinary orthopaedic surgery. However, the use of autogenous bone graft is limited by the additional surgical time required to harvest the graft, the morbidity associated with the donor site, and the limited availability of cancellous bone, especially in feline patients. Various allografts and bone graft substitutes are available commercially but have not been fully evaluated for efficacy in the cat. The purpose of this study was to compare the incorporation of autogenous and allogenous cancellous bone graft and Bioglass®, a synthetic bone graft substitute, in femoral defects in cats. Four (4.0 mm diameter) defects were created in the lateral diaphyseal cortex of the left femur with an orthopaedic drill. In each femur, one of the cortical defects was filled with autogenous cancellous graft (harvested from the tibia), one was filled with allogenic cancellous graft, and one was filled with Bioglass. The fourth defect remained unfilled. Graft incorporation within the femoral defects was evaluated by radiographic evaluation every two weeks. Six weeks after the grafting procedure, the cats were euthanatized and high detailed radiography, dual energy X-ray absorptiometry (DEXA), histopathology and histomorphometry of the defects were performed. Satisfactory bone healing was observed within all of the defects.

Autogenous Bone Grafting

Background Isolated capitate nonunion is rare. No consensus on the appropriate treatment for this condition exists. Case Description We reported two cases of capitate fracture nonunion presenting several months after untreated high-impact wrist trauma. Treatment was delayed as both patients' nonunions were missed on conventional radiographs. Both were ultimately diagnosed with advanced imaging and successfully treated with internal fixation and autogenous bone grafting. The relevant literature pertaining to capitate nonunion was reviewed. Literature Review Immobilization and internal fixation with bone grafting for capitate nonunion have been described in the literature. Loss of vascular supply and progression to avascular necrosis is a concern after capitate nonunion. Clinical Relevance We present two cases and review the literature on the diagnosis and treatment of this rare injury to guide management. Internal fixation with autogenous bone grafting could play a role in management for this rare condition.
