The magnitude of the hallux valgus deformity was not associated with Achilles or gastrocnemius tendon tightness, increased first ray mobility, bilaterality or pes planus. Neither the magnitude of the preoperative angular deformity nor increasing age had any association with the magnitude of the first metatarsophalangeal joint range of motion. Constricting shoes and occupation were implicated by 35 (34%) patients as a cause of the bunions. A familial history of bunions, bilateral involvement, female gender, a long first metatarsal, and an oval or curved metatarsophalangeal joint articular surface were common findings. Increased first ray mobility and plantar gapping of the first metatarsocuneiform joint were more common in patients with hallux valgus than in the general population (when compared with historical controls).

By 24 months, ankles treated with STAR ankle replacement (in both the Pivotal and Continued Access Groups) had better function and equivalent pain relief as ankles treated with fusion.

Hallux rigidus was not associated with elevatus, first ray hypermobility, a long first metatarsal, Achilles or gastrocnemius tendon tightness, abnormal foot posture, symptomatic hallux valgus, adolescent onset, shoewear, or occupation. Hallux rigidus was associated with hallux valgus interphalangeus, bilateral involvement in those with a familial history, unilateral involvement in those with a history of trauma, and female gender. Metatarsus adductus was more common in patients with hallux rigidus than in the general population but a clear correlation was not found. Additionally, a flat or chevron-shaped metatarsophalangeal joint was more common in hallux rigidus patients.

This ad hoc committee was appointed to evaluate the methods of measurement in quantitating pre-and postoperative hallux valgus angles and make recommendations. The previous AOFAS research committee report had also done this in 1984. 37The most commonly used angular measurements to assess the severity of a pre-operative hallux valgus deformity and the magnitude of the postoperative correction are the hallux valgus angle and the 1-2 intermetatarsal angle. The use of these quantitative angular measurements in assessing hallux valgus deformities is based upon the belief that they are reliable, repeatable, and provide a constant value for comparison of different studies." While it has been demonstrated that both of these angles can be reliably measured from both an intra-observer and inter-observer standpolnt,"" there is considerable evidence that these angular measurements are obtained and reported in an inconsistent fashion.In evaluating published reports on hallux valgus correction, the information on angular measurements presented is variable. In few instances, a precise description as well as a consistent diagram and/or representative radiograph is presented,"> but generally there are either no recorded measure-

In the present study, lateral ankle reconstruction with a direct anterior talofibular ligament repair and free gracilis tendon graft augmentation resulted in a high percentage of successful results, excellent ankle stability with a minimal loss of ankle or hindfoot motion, and marked reduction of pain at an average follow-up of almost 2 years.

In an 11-year retrospective study of 45 patients (60 feet) with juvenile hallux valgus, a multiprocedural approach was used to surgically correct the deformity. A Chevron osteotomy or McBride procedure was used for mild deformities, a distal soft tissue procedure with proximal first metatarsal osteotomy was used for moderate and severe deformities with MTP subluxation, and a double osteotomy (extra-articular correction) was used for moderate and severe deformities with an increased distal metatarsal articular angle (DMAA). The average hallux valgus correction was 17.2 degrees and the average correction of the 1-2 intermetatarsal angle was 5.3 degrees. Good and excellent results were obtained in 92% of cases using a multiprocedural approach. Eighty-eight percent of patients were female and 40% of deformities occurred at age 10 or younger. Early onset was characterized by increased deformity and an increased DMAA. Maternal transmission was noted in 72% of patients. An increased distal metatarsal articular angle was noted in 48% of cases. With subluxation of the first MTP joint, the average DMAA was 7.9 degrees. With a congruent joint, the average DMAA was 15.3 degrees. In patients where hallux valgus occurred at age 10 or younger, the DMAA was increased. First metatarsal length was compared with second metatarsal length. While the incidence of a long first metatarsal was similar to that in the normal population (30%), the DMAA was 15.8 degrees for a long first metatarsal and 6.0 degrees for a short first metatarsal. An increased DMAA may be the defining characteristic of juvenile hallux valgus. The success of surgical correction of a juvenile hallux valgus deformity is intimately associated with the magnitude of the DMAA. Moderate and severe pes planus occurred in 17% of cases, which was no different than the incidence in the normal population. No recurrences occurred in the presence of pes planus. Pes planus was not thought to have an affect on occurrence or recurrence of deformity. Moderate and severe metatarsus adductus was noted in 22% of cases, a rate much higher than that in the normal population. The presence of metatarsus adductus did not affect the preoperative hallux valgus angle or the average surgical correction of the hallux valgus angle. Constricting footwear was noted by only 24% of patients as playing a role in the development of juvenile hallux valgus. There were six recurrences of the deformities and eight complications (six cases of postoperative hallux varus, one case of wire breakage, and one case of undercorrection).
