Basal closing wedge osteotomy for correction of hallux valgus and metatarsus primus varus: 10- to 22-year follow-up.

Between 1974 and 1985, 59 patients (83 feet) underwent basal closing wedge osteotomy in combination with a bunionectomy and a lateral soft tissue release for correction of hallux valgus and metatarsus primus varus at this institution. Of the original 59 patients, 42 patients (60 feet) with at least 10 years of follow-up (average, 194 months; range, 144-266 months) were available for this study. Results were analyzed by review of the medical records and plain radiographs, a standardized clinical questionnaire, and physical examination. Of the 60 feet, patients rated outcomes as excellent or good in 51 feet (85%) and rated cosmesis as excellent or good in 44 feet (73%). Radiographically at final follow-up, hallux valgus and intermetatarsal angles averaged 19.9 degrees (range, 0-40 degrees) and 6.7 degrees (range, 0-18 degrees), respectively. The sesamoid position was corrected from an average preoperative grade of 2.6 to a grade of 0.9 at final follow-up. The average shortening of the first metatarsal was 5 mm. The disadvantages of the closing wedge osteotomy are that it is technically demanding and it entails the risk of shortening, dorsal malalignment, and metatarsalgia. In the current study, long-term complications included hallux varus deformity (16 feet), dorsal malalignment (15 feet), and metatarsalgia (14 feet). Despite good correction of the intermetatarsal angle and sesamoid position, the clinical results and the incidence of complications after basal closing wedge osteotomy were not as favorable as those reported for other procedures in the literature. Therefore, alternative procedures, such as the basal crescentic osteotomy or the basal chevron osteotomy, should be used.

A method of predicting the degree of functional correction of the metatarsus primus varus with a distal lateral displacement osteotomy in hallux valgus.

Metatarsus primus varus may be an important pathologic component in hallux valgus deformity. The correction of the pathologic intermetatarsal angle M1 M2 is essential for providing an acceptable alignment of the hallux. The distal lateral displacement osteotomy of the first metatarsal (Chevron or Mitchell) provides correction of the intermetatarsal angle M1 M2. The present paper describes a simple method of calculating preoperatively the maximum possible correction through such osteotomies. This method, based on the measurement of the length of the first metatarsal and the width at the osteotomy site, projects the amount of correction and, furthermore, provides the limits of angular correction through such osteotomies performed distally.

Considerations for the Lapidus operation.

The Lapidus operation for correction of severe hallux valgus with metatarsus primus varus has never been well accepted by foot surgeons. The main reason for this has been the poor results obtained from its misuse. Lapidus strongly advocated the operation as a virtual panacea for correction of all degrees of severity of these deformities in both young and old patients. The technique, however, is appropriate for severe metatarsus primus varus with hallux valgus, in the foot with marked first ray hypermobility and collapsed distal-medial arch. The purpose and proper indications for the Lapidus operation are discussed, and the technique is illustrated.

[Intermediate results following subcapital metatarsal osteotomy in the therapy of hallux valgus with metatarsus primus varus].

71 feet were investigated after subcapital modified osteotomy of the metatarsus according to Kramer for an average follow-up period of 19 months. Mean improvement of the Hallux valgus angle was 10 degrees whereas the intermetatarsal angle was improved by 4 degrees on average. The high degree of satisfaction of patients (83%) with the outcome of this surgical method suggest its application in cases of medium metatarsus primus varus within hallux valgus deformations when the metatarso-phalangeal joint is not affected. In patients aged 50 years and older as well as in cases of MT I varus exceeding 18-20 degrees this operation should strictly be limited to the cases indicated above.

Hallux valgus and metatarsus primus varus treated by bunionectomy and proximal metatarsal osteotomy.

Sixteen feet with hallux valgus and metatarsus primus varus have been treated by excision of the exostosis of the first metatarsal head, advancement of the medial capsule and the abductor hallucis, release of the lateral capsule and adductor tendon, and open-wedge osteotomy at the base of the first metatarsal inserting a bone graft. During a three-year period ther have been no nonunions of the osteotomy, and satisfactory maintenance of the corrections has occurred. This method is preferred over distal metatarsal osteotomy.

Geometric data of hallux valgus feet.

The aim of this study is to find basic quantitative geometric data that may contribute to the understanding of the etiology of hallux valgus. Embalmed specimens with existing hallux valgus (N = 39) were dissected; 28 variables were measured with a Vernier caliper gauge and toe goniometer. Correlations between pairs of independent variables were calculated. Linear dependency of the hallux angle, varus angle, and the width of the forefoot on a number of independent variables was analyzed by multiple linear regression. A least squares method and a stepwise procedure were used. The distance from the tendon of the flexor hallucis longus muscle to the head of the first metatarsal bone explains more than other variables the variation in hallux angle and width of the forefoot. A widened forefoot is significantly correlated with both hallux and varus angles. The interrelation of the predictor parameters illustrates the complicated hallux valgus phenomenon.

Single absorbable polydioxanone pin fixation for distal chevron bunion osteotomies.

The distal chevron osteotomy is a well-established technique for correction of symptomatic mild to moderate metatarsus primus varus with hallux valgus deformity. Fixation of the osteotomy ranges from none to bone pegs, Kirschner wires, screws, or absorbable pins. We evaluated one surgeon's (J.K.D.) results of distal chevron osteotomy fixation with a single, nonpredrilled, 1.3-mm poly-p-dioxanone pin and analyzed any differences in patients with unilateral or bilateral symptomatic metatarsus primus varus with hallux valgus deformities. All osteotomies healed without evidence of infection, osteolysis, nonunion, or necrosis. Equal correction was achieved in unilateral and bilateral procedures. The technique is quick and easy, and adequate fixation is achieved.

Correction of hallux valgus and metatarsus primus varus. Using the Cedell technique.

The Cedell procedure consists of: a proximal valgus osteotomy of the first metatarsal bone to correct the metatarsus primus varus, a soft tissue plasty at the first metatarsophalangeal joint with lateral release, and tightening of the medial capsule to correct the hallux valgus. A total of 45 operations in 31 patients (2 men and 29 women) were performed. Forty-one of these operations were followed. The average age at surgery was 24 years (range 16 to 43 years), and the average follow-up time was 23 months (range 8 to 56 months). The postoperative decrease in the intermetatarsal angle averaged 10 degrees, and the average decrease in the metatarsophalangeal angle was 26 degrees. Only a few postoperative complications were observed. At the time of follow up, 75% of the patients had no pain, 23% had only slight pain, and 2% had severe pain. Ninety-five percent were cosmetically satisfied with the operation. The Cedell operative technique has proved to be an effective procedure to correct the combined hallux valgus and metatarsus primus varus in younger patients.

The management of malalignment in hip revision surgery.

When facing revision surgery, the deformation of the femur must be considered for the important implications in the strategy of the operation and the choice of the implant. Deformation can occur in varus and retroversion, or both, in different degrees. For severe varus deformations a straightening osteotomy is generally indispensable and different types of distal fixations of the implant are necessary; in milder deformations other solutions are possible. Retroversion can be generally managed with proximally modular stems, stems without metaphyseal component, or, rarely, with a derotation osteotomy.
