[Analysis of pressure distribution for the evaluation of gait in patients with hallux valgus surgery].

Peak pressures and regional impulses were determined under the feet of 58 patients treated by a Keller/Brandes surgery. The values were taken in walking by means of a capacitance pressure distribution platform and compared to the pressure values of a normal collective (n = 111). 95% of the patients were satisfied with the surgery. A shift of the pressure and the regional impulse from the hallux to the metatarsal heads, especially to the III. metatarsus could be found.

Chevron osteotomy in hallux valgus. Ten-year results of 112 cases.

The Chevron osteotomy was described in 1976. There have, however, been only short- to mid-term follow-up reviews, often with small numbers of patients. We looked at 112 feet (73 patients) with a minimum follow-up of ten years following Chevron osteotomy with a distal soft-tissue procedure. Clinical evaluation was calculated using the hallux score of the American Orthopedic Foot and Ankle Society (AOFAS). For 47 feet (30 patients), the results were compared with those from an interim follow-up of 5.6 years. The AOFAS-score improved from a pre-operative mean of 46.5 points to a mean of 88.8 points after a mean of 12.7 years. The first metatarsophalangeal (MTP) angle showed a mean pre-operative value of 27.6 degrees and was improved to 14.0 degrees. The first intermetatarsal (IM) angle improved from a pre-operative mean value of 13.8 degrees to 8.7 degrees. The mean pre-operative grade of sesamoid subluxation was 1.7 on a scale from 0 to 3 and improved to 1.2. Measured on a scale from 0 to 3, arthritis of the first MTP joint progressed from a mean of 0.8 to 1.7. Comparing the results in patients younger and older than 50 years, the Chevron osteotomy performed equally in both age groups. Analysing the subgroup of 47 feet with a post-operative follow-up of both 5.6 and 12.7 years, the AOFAS pain and the overall score showed a further improvement between both follow-up evaluations. The MTP angle, first IM angle and sesamoid position remained unchanged. The progression of arthritis of the first MTP joint between 5.6 and 12.7 years post-operatively was statistically significant. Only one patient required a revision procedure due to painful recurrence of the deformity. Excellent clinical results following Chevron osteotomy not only proved to be consistent, but showed further improvement over a longer follow-up period. The mean radiographic angles were constant without recurrence of the deformity. So far, the statistically significant progression of first MTP joint arthritis has not affected the clinical result, but this needs further observation.

[Considerations on the surgical treatment of hallux valgus].

The authors, after showing a critical analysis of the most interesting operations for correction of valgus big toe in the history of orthopaedics, show the technique they followed, as well as the results obtained, in a specimen chosen among the patients treated with such method.

The Akin procedure in hallux valgus.

A retrospective study of 28 Akin procedures was undertaken to assess their results. Patient satisfaction, clinical findings and roentgenographic measurements were evaluated after follow-up periods of 12 to 42 months. The outcome was excellent in nearly 60% of the patients, especially those whose discomfort was related to the laterally deviated great toe and to the prominence of the first metatarsal head.

Chevron osteotomy of the first metatarsal for hallux valgus.

A retrospective study of 50 chevron osteotomies evaluated subjective and objective functional and cosmetic results, which were in keeping with other reported studies--i.e. satisfactory subjective cosmesis in 98%; excellent or good pain relief in 84%; and satisfactory objective cosmesis in 84%. The correction of the 1st intermetatarsal angle averaged 3.3 degrees, and that of the metatarsophalangeal valgus averaged 15 degrees. Average active range of motion of the 1st metatarsophalangeal joint was 60 degrees. Complications were generally mild and asymptomatic, and were usually iatrogenic. The findings of this study, together with information gained from a concomitant stress analysis, led to recommendations regarding operative technique.

Surgery for hallux valgus with proximal crescentic osteotomy causes variable postoperative pressure patterns.

We prospectively evaluated the results of plantar pressure measurement in 32 patients (43 feet) who had a proximal crescentic osteotomy of the first metatarsal with a modified McBride procedure. The procedure's effectiveness in increasing weightbearing under the first ray, decreasing pressure under the second metatarsal head, and the relationship of radiographic measurements of first metatarsal length and position to postoperative pressure measurements were evaluated. Mean followup was 29 months. Average peak pressure increased postoperatively under the second metatarsal head. Almost identical numbers of feet had first metatarsal elevation (12) or depression (11) greater than 2 mm. Radiographic evidence of first metatarsal elevation, but not shortening, was associated with diminishing peak pressure and pressure-time integral under the first metatarsal head and hallux. Five feet that had first metatarsal elevation greater than 2 mm had new second metatarsal transfer lesions develop. Eleven feet preoperatively and nine feet postoperatively had symptomatic second metatarsal pressure lesions. One lesion persisted, 10 resolved, and eight new lesions developed. Control of the crescentic osteotomy in the sagittal plane was unpredictable despite modification of the surgical technique to plantarly displace the distal segment of the first meta-tarsal. Although average second metatarsal pressure increased postoperatively, there was variability in the correlation of radiographic change and pedobarographic measurements.

Preoperative planning for hallux valgus bunion surgery: photonics versus templates.

Photonic techniques such as CAD can now be applied to foot and ankle surgery for preoperative planning. Perhaps "CAS" (computer-aided surgery) or "surgitecture" would be more appropriate terms for our field and application. Achievements in this new frontier depend on present and future generations of podiatrists who are willing to challenge themselves to explore the potential of photonics and to refine its capabilities.

[Treatment of hallux valgus. Limitations and indications for exostosectomy].

The authors have treated 63 halluces valgi by simple excision of the exostosis and bunion. In 18 the results were unsatisfactory. It was concluded that this procedure was worthwhile in the following conditions: --absence of arthrosis,--halux valgus of less than 30 degrees,--and an angle between the first and second metatarsal of less than 10 degrees. The age of the patient and the morphology of the feet (Egyptian or Greek) did not influence the results. Fixation of the capsule to the metatarsal at the end of the operation is recommended.

The surgical treatment of hallux valgus using the modified Z-osteotomy.

Numerous therapeutic options are available in treating the painful bunion. The procedure that accomplishes the desired results and correction must be carefully matched with the underlying pathologic deformity. For the majority of patients, in the author's hands, the Silver Triad (eminence resection, lateral release, and medial plication) combined with the Z-1st metatarsal osteotomy is the ideal procedure.

[Surgical therapy of hallux valgus: technics, cases, results (communication of the 8th Congress of the Italian Society for Medicine and Surgery of the Foot, Rome 1978)].

After a careful description of the surgical method according to Regnauld for the bloody treatment of valgus big toe, followed by them since 1974, the Authors show their casuistry. The results are considered from the aesthetic and functional standpoint; the single patients' opinion is also reported. The Authors, as a conclusion, declare themselves satisfied pith this method, which not only gives excellent aesthetic and functional results, but also caused no relapses.

[Treatment of hallux valgus (review of cases operated on from 1976 to 1978 )].

The AA. reporton the long-term check-up (from 4 to 6 years) about 50 cases of big toe valgls treated with regularization of esostosus, correction of 1 metatarsus and plastic-capsule. The valuation of the results, executed on the ground parameters: pain, mobility, functionality, residual deformation, allows the Authors to confirm the validity of that therapeutical procedure.
