Placement of solid screws with cannulated precision.

Cannulated screws can be inserted in a precise manner with minimal damage to surrounding structures but lack the mechanical strength of solid screws. Our method allows the insertion of a solid screw with the precision of the cannulated technique. With the use of equipment from a variety of operative sets from one manufacturer, a "custom" equipment set can be developed. This "custom" equipment set allows the surgeon to benefit from the strength of solid screws while preserving the precision of a cannulated system.

Evaluation of fibula free flap donor site morbidity.

OBJECTIVE: To evaluate foot and ankle function in a series of patients undergoing fibula microvascular free tissue transfer. STUDY DESIGN: A nonrandomized, nonblinded analysis was performed using the ankle-hindfoot scale as well as radiographic analysis to determine donor site morbidity. RESULTS: Overall, foot ankle function was deemed to be good in this series of patients. Average ankle-hindfoot score was 84.82 of a possible 100 (range, 55-100). Radiographic analysis of donor and contralateral ankles showed no difference in the syndesmotic space or medial clear space. Only 1 patient had increased talar tilt compared with the contralateral side, although this patient had preservation of stability. CONCLUSION: Fibula free flap harvest appears to be associated with acceptable donor site morbidity and preservation of good foot and ankle function in most individuals.

Adding stability to the crescentic basilar first metatarsal osteotomy.

Crescentic basilar osteotomies for metatarsus primus varus and hallux valgus allow for substantial correction of the first intermetatarsal angle and the hallux valgus angle. Crescentic osteotomies have two well-documented pitfalls: sagittal plane instability and difficulty in fixation. We describe the addition of a plantar shelf to crescentic basilar osteotomy that allows for easier fixation and less risk of elevation of the first metatarsal postoperatively. This plantar shelf is made in the metaphyseal portion of the first metatarsal, which provides the benefit of better bone healing. In 20 patients, we found an average reduction in the intermetatarsal angle of 9.3 degrees and an average reduction in the hallux valgus angle of 21.8 degrees. Eight weeks postoperatively, only one patient showed elevation of the first metatarsal.

Bone matrix therapy for aneurysmal bone cysts.

Aneurysmal bone cysts are unique pathologic entities that cause pain and local osseous destruction. Many surgical treatment modalities have been described. This article reports on the case of a 16-year-old high school athlete with left heel pain due to an aneurysmal bone cyst in the calcaneus. Curettage of the bone cyst was performed, and the void was filled with a commercially available mixture of cancellous bone and demineralized bone matrix. Early return to athletic activity was achieved, with no recurrence noted at 3-year follow-up.
