Clinical Considerations

INTRODUCTION: Secondary bone grafting consists in a routine procedure on the treatment of patients with alveolar cleft. Usually, it is performed by the end of the mixed dentition, when the permanent canine is erupting, with autogenous cancellous bone from the iliac crest. OBJECTIVE: The present article discusses the alternative of autogenous bone grafting with allogeneic bone, obtained from human bone bank, illustrating the result with the presentation of a clinical case of left unilateral alveolar cleft.

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.

<p class="Abstract">The alveolar cleft is known as the developmental defect of bone in alveolar process of maxillae which occurs in 75% of the cleft lip and palate patients with different types of clinical presentation like unilateral or bilateral and complete or incomplete. Secondary alveolar cleft reconstruction with autogenic spongy bone grafting (osteoplasty) at the stage of mixed dentition is commonly accepted treatment to help in the maintenance of maxillary arch continuity, repairing of oronasal fistula, eruption of the permanent dentition, enhancement of nasal symmetry through providing alar base support and improving speech. As of late, conflicting argument of alveolar cleft management is continuing regarding treatment planning with timing, graft materials, surgical techniques as well as methods of evaluation of the progress of alveolar osteoplasty. Now-a-days, experiments have made for the application of allogeneic bone, artificial bone, and recombinant human bone morphogenetic protein (rhBMP), along with growth factors to diminish the donor-site morbidity associated autogenic bone grafting. The purpose of this review is to discuss about pathogenesis and aetiology of cleft defects, surgical techniques, assessment of progress of alveolar bone graft and proposed future materials for bone graft.</p>

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.

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.

Secondary autogenous bone grafting is the gold standard for the closure of an alveolar cleft. A preoperative surgical planning helps to determine the optimal shape and volume of the graft, that ideally guide canine eruption to the cleft area and ensure adequate nasal support. The authors describe their experience with design and use of an individually shaped 3D template for an autologous bone graft with fibrin glue for correct volume design. The conforming template is designed using freeware and open source software, it is manufactured by means of additive technology using autoclavable resin.
