Purpose of the study: Hallux valgus is often associated with metatarsalgia due to insufficiency of the first ray. The purpose of this prospective study was to learn whether osteotomy of the first metatarsal can correct both conditions.

Material and methods: This series included 35 women and 2 men, mean age 55 years. Metatarsalgia predominated in M2 in these patients with a round forefoot. Pain was a constant sign. Thirty-six patients wore special shoes for comfort with or without an orthesis. The mean preoperative metatarsal varus, measured radiographically was 16°. Scarf osteotomy used a horizontal cut at of the first metatarsal forming a 45° angle with the plantar aspect. Patients were reviewed at three years with a computed tomography of the forefoot. The Kita-oka score was determined.

Results: Thirty-four feet were pain-free at last follow-up. The frontal scan of the forefoot showed the shaft of the first metatarsal had been lowered 2 mm on average. According to the Kitaoka score, outcome was good or very good for 31 feet, fair for 5 and poor for 5. There was a significant correlation between lowering of the first metatarsal and persistent metatarsalgia.

Discussion: Barouk suggested the Scarf technique does not enable sufficient lowering of the first row to correct for around forefoot. The CT scan however showed the metatarsal was lowered 2 mm, which would appear to be sufficient to correct for the insufficient weight-bearing. The result of this series would appear to show that outcome is better then hallux valgus cure plus Weil oseotomy if there is no hallomegaly.

Conclusion: This series shows the usefulness of lowering the first metatarsal for the treatment of hallux valgus with metatarsalgia without hallomegaly.

Purpose: We report a series of 46 cases of subtal instability associated or not with tibiotarsal lesions treated by Castaing ligamentoplasty between 1988 and 1999.

Material and methods: Preoperatively, symptoms were: instability, twisted ankle, recurrent ankle sprains, pain. A tarsal sinus syndrome was found in 39%. MRI was performed in all 46 patients and revealed ligamentary lesions in all case. Outcome was assessed with the Kitoaka score.

Results: At mean 5.7 years follow-up instability had resolved in 80% of the ankles. Total pain relief was noted in 63%. Physical examination demonstrated reduced motion of the subtalar joint with inversion in 43% ranging from 50% to 70% compared with healthy side, but without significant functional impact. Radiographic signs of early-stage degeneration were found in three patients. Overall outcome was very good in 82%, fair in 11%, and poor in 7%. The index of patient satisfaction was 87%.

Discussion: This series showed a correlation between body mass index greater than 26 or constitutional laxity and fair or poor results. Furthermore, longer time between the first sprain and surgical management of the residual instability led to less satisfactory final outcome. Comparison with other ligamentoplasty techniques showed similar results.

Conclusion: The Castaign procedure provides results similar to other ligamentoplasty techniques. Direct repair of the subtalar ligaments should however be preferred as the first-intention procedure, reserving Castaign ligamentoplasty for cases of failed repair.

Purpose: We report a series of 32 cases of recurrent hallux valgus treated by metatarsophalangeal arthrodesis and followed for at least five years.

Material and methods: Mean follow-up after the initial surgery was 11 years. All patients complained for pain of the forefoot. The mean phalangeal valgus was 39° with metatarsalgia in 16 cases. According to the Regnauld classification, the metatarsophalangeal space of the great toe was grade 1 in two, grade 2a in eight, grade 2b in six, and grade 3 in sixteen. Arthrodesis was achieved with an axial screw and adductor hallux plasty. Results were assessed at least five years after surgery according to the Kitaoka criteria.

Results: At last follow-up 78% of the patients were pain free. The valgus deviation was corrected with a mean angle of 19°. The arthrodesis fused in 90.6% of the cases. Statistical analysis revealed the influence of pre- and postoperative great toe valgus on the final result. The final results were less satisfactory with older age. Outcome was very good in 84%, fair in 6%, and poor in 10%.

Discussion: These results demonstrate that arthrodesis of the great toe is not an invalidating solution. Interpha-langeal joint degeneration can develop after excessive solicitation of the articulation.

Purpose: The advent of lapaoscopic disectomy has made it possible to cure discal herniation with minimal trauma and no limitations on indications. We have adopted the technique described by J. Destandau since June 1998. The purpose of this work was to report our early results.

Material and methods: Forty patients were included in a period from June 1998 to August 2000. There were 24 men and 16 women, mean age 43 years (24–78). Eleven patients had an associated stenosis of the spinal canal. Accelerated rehabilitation was employed. Sitting and driving were allowed early.

Results: Mean follow-up was 13 months (2–27 months). Mean operative time was 63 minutes (30–150 min). Mean hospital stay was 3.92 days (2–10). There were 29 patients without stenosis of the lumbar canal. In this subgroup, outcome was excellent in 69%, good in 21% (six patients), fair in 3% (one patient), and poor in 7% (two patients). For the PROLO score, three patients were who were retreated were not included in the analysis. Outcome was excellent in 73% (19 patients), good in 12% (three patients), fair in 12% (three patients, and poor in 4% (one patient). In patients with lumbar canal stenosis, (eleven patients), three were reoperated for wider decompression; there was no haematoma. One patient was reoperated for deep infection. For the other patients the WADDELL score was excellent in five and good; in two the PROLO score was excellent in six and poor in one.

Discussion: The technique favoured a narrow approach. Shorter exposure preserved the anatomy, but for the three patients with an associated stenosis, reoperation was necessary for decompression. For the cases without complications, we noticed that recovery was very rapid, a finding which is exceptional with the conventional technique.

Conclusion: Our early experience with this technique has demonstrated that laparoscopic discectomy is feasible and safe. An associated stenosis is a limitation; we recommend systematic decompression in association with the discectomy.
