Allan L. Bernstein, DPM, FACFAS

A 16-month preliminary study was performed on 58 patients for corrective surgery of hallux abducto valgus, with AO' screw fixation. The procedure is a modification of the bi-plane Austin procedure, called a tricorrectional bunionectomy. The authors present the procedure with objective and subjective findings. The principles of bone healing and internal fixation using AO screw fixation are discussed.

Tricorrectional Bunionectomy for Surgical Repair of Juvenile Hallux Valgus
Allen J. Selner, DPM
Mark D. Selner, DPM
Rick A. Tucker, DPM
Greg Eirech, DPM

The authors propose the use of the tricorrectional bunionectomy as an alternate correction of severe deformity in juvenile hallux valgus. In the past, hallux valgus surgery in juveniles has been avoided. A follow-up study of the tricorrectional bunionectomy as the surgical treatment for juvenile bunion deformity in seven patients is presented.

The authors propose the use of the tricorrectional osteotomy for treatment of severe hallux limitus/rigidus as an alternative to joint-destructive procedures. A study of 19 patients with follow-up treatment ranges of 10 months to 6 years postoperatively was performed. Data were collected on preoperative and long-term postoperative x-rays, range of motion assessment, F-scan studies, and subjective patient questionnaires. High patient satisfaction along with increased range of motion, minimal complications, and an early return to activities make this an ideal procedure for grades II, III, and IV hallux limitus/rigidus.

Tricorrectional Bunionectomy for Correction of High Intermetatarsal Angles
Allen J. Selner, DPM
Steven L. Ginex, DPM
Marc D. Selner, DPM

The authors propose the use of the tricorrectional bunionectomy as a viable procedure for correction of high intermetatarsal angles. The tricorrectional bunionectomy was performed on 39 patients (51 feet). All patients had intermetatarsal angles of 16° or greater. The average follow-up period was 12.8 months. The authors believe this procedure is an excellent alternative to more disabling base osteotomies.

A longitudinal outcome study of the tricorrectional bunionectomy with AO screw fixation for the correction of hallux abducto valgus was undertaken involving 84 consecutive patients (121 feet) with a mean age of 48.4 years who underwent the procedure over a 6-month period. Preoperative and postoperative measurements of forefoot angles were calculated, with the following mean results obtained: intermetatarsal angle of 14.46° corrected to 5.72°, hallux abductus angle of 26.38° corrected to 11.65°, proximal articular set angle of 19.85° corrected to 6.06°, and tibial sesamoid position of 4.75 corrected to 1.87. The average time to return to athletic shoes was 12.63 days. Postoperative complications were minor, with no delayed unions, malunions, hematomas, bone infections, or hallux varus. Long-term follow-up (mean, 21.33 months) using the American Orthopaedic Foot and Ankle Society's objective Hallux Metatarsophalangeal-Interphalangeal Scale revealed an overall mean score of 88.94 points out of a possible 100. An excellent mean result of 95 points out of a possible 100 on the subjective patient rating scale was also reported. (J Am Podiatr Med Assoc 89(4): 174-182, 1999)

We present a radiographic analysis of 91 failed hallux abducto valgus surgeries. Patients were categorized by type of postoperative complication: hallux varus, hallux limitus, or recurrent hallux abducto valgus deformities. All deformities were radiographically evalutated preoperatively and after correction using tricorrectional bunionectomy. Analysis of the surgical revisions showed improvement in radiographic parameters, including the intermetatarsal angle, hallux abductus angle, proximal atricular set angle, and tibial sesamoid position. We conclude that tricorrectional bunionectomy is a versatile procedure that can be used when addressing a residual deformity after failed hallux abducto valgus surgery.
