Introduction and purpose: Numerous surgical procedures have been developed for the treatment of chronic ankle instability, which can be broken down into two: tenodesis of the peroneus brevis and ligament capsuloplasty. We assess the indications for these procedures, discuss their advantages and disadvantages based on a comparative review, and describe an algorithm in the treatment of this pathology.

Materials and methods: We reviewed 21 patients who underwent surgery from 1997 to 2001. In 10 of the patients the operation consisted of a Castaing II procedure with tenodesis of the peroneus brevis, and in 11 a Larsson procedure was performed as a ligament capsuloplasty. The ankle was evaluated using the AOFAS scale.

Results: The age difference between the two groups, which was 40 for those undergoing the Castaing II procedure and 28 for the Larsson technique. The mean AOFAS score was 80% (min. 70%, max. 95%) for the Castaing II procedure and 86% (min. 71%, max. 97%) for the Larsson technique.

Conclusions: The use of tenodesis with the peroneus brevis is indicated for severe ankle instability, failed anatomical repairs and in patients with connective tissue pathology. A capsuloplasty that attempts to reconstruct the lateral ligaments of the ankle as anatomically as possible is indicated for mild-to-moderate chronic instability in young patients.

Objective: The objective of this retrospective study is to evaluate our results with proximal closing-wedge osteotomy of first metatarsal for the treatment of hallux valgus with severe intermetatarsal (IM) angle and normal proximal articular set angle (PASA).

Material and methods: We reviewed 110 patients (141 feet) who had been treated by proximal closing-wedge osteotomy of first metatarsal between March-97 and February-04. 87% were women and the mean age was 47.8 years. A single cannulated screw was used for osteotomy fixation in 82% of patients. Additional procedures as phalangeal osteotomy or Keller resection were done when necessary.

Results: With a mean follow-up of 42.3 months, correction of the deformity was good or excellent in 80.5% of cases and fair in 15.4%. Pain due to bunion disappeared in 94.3% of feet. Mean preop IM (angle) was 17.3 and postop was 7.9. Metatarsal-phalangeal angle improved from 42.4 to 15.9. Fusion was achieved in 6.8 weeks (average). Complications were: hypercorrection in 13 feet (2 required reoperation); recurrence of deformity in 10 feet (1 reoperation); central metatarsalgia in 8 feet. Neither infection nor nonunions were observed. Patient satisfaction was excellent or good in 92.7% of patients.

Conclusion: Proximal closing-wedge osteotomy of first metatarsal is a good technique for the treatment of hallux valgus with severe IM angle and normal PASA. It is an easy and reproducible technique with good results, low number of complications and a high rate of patient satisfaction
