Distal tibia bone graft for arthrodesis of the foot and ankle.

Forty patients since 1988 have had distal tibial bone grafting for 41 arthrodeses of the foot and ankle. Bone graft is obtained through a cortical window made just above the medial metaphyseal distal tibial flare. Average follow-up was 23.3 months. Forty of 41 arthrodesis sites fused; there was only one nonunion. There were no delayed unions. There were no complications at the donor site based on patient examination and radiographs. Ipsilateral ankle motion was not affected by the bone graft procedure. Cited complications from iliac crest bone graft include donor site pain, blood loss, heterotopic bone formation, pelvic instability, iliac hernia, infection, fracture, and deformity. Complications with allografts include disease transmission and immune response. These are avoided by using locally obtained distal tibia autograft for arthrodeses in the foot and ankle.

Arthrodesis of the first metatarsophalangeal joint with Vitallium plate fixation.

Forty-seven patients (58 feet) underwent first metatarsophalangeal joint fusion with a small Vitallium plate (Howmedica, Inc., Rutherford, NJ). Congruous joint surfaces were prepared with either cone-shaped or cup-shaped reamers. At an average follow-up of 19.2 months, 98% (57 feet) were successfully fused. Ninety-three percent (54 feet) noted good or excellent results. Plate removal was necessary in only 7% (4 feet) of cases. Complications included nonunion with plate breakage in 2% (1 foot) and delayed union in 2% (1 foot) of cases. This technique was useful and predictable in achieving successful fusion of the first metatarsophalangeal joint.

Ankle arthrodesis: a long-term study.

Few studies of ankle arthrodesis have assessed tarsal mobility. This study was performed to evaluate radiographically the effect of ankle arthrodesis on tarsal motion. Thirty patients (31 ankles) returned for clinical and radiographic examination, review of charts, and completion of questionnaire forms. Radiographs were evaluated for success of fusion, position of fusion, tarsal motion, hindfoot position, and subtalar and midtarsal arthritis. The median follow-up time was 7.0 years (range 2-20 years). Results showed that fusion was achieved in 22 patients (71%). The evaluation score based on the grading system of Mazur et al. correlated with success of fusion and patient satisfaction. However, no correlation existed between evaluation score and tarsal motion or position of fusion in the sagittal or coronal planes. Radiographic evaluation showed no significant difference between tarsal motion of the fused side and the unfused side. Tarsal mobility was not affected by ankle arthrodesis or by the techniques performed to achieve fusion.
