BACKGROUND: Hallux abducto valgus (HAV) is one of the most common forefoot deformities in adulthood with a variable prevalence but has been reported as high as 48%. The study proposed that HAV development involves a skeletal parameter of the first metatarsal bone and proximal phalanx hallux (PPH) to determine if the length measurements of the metatarsal and PPH can be used to infer adult HAV. METHODS: All consecutive patients over 21 years of age with HAV by roentgenographic evaluation were included in a cross-sectional study...

: First metatarsophalangeal joint arthritis can stem from a biomechanical imbalance as in hallux abducto valgus, metabolic arthritidies such as rheumatoid or gout, and even in posttraumatic cases. Advanced arthritis in the foot and ankle can often become debilitating. Surgical intervention is often necessary. Revision of failed first metatarsophalangeal joint arthroplasty is often in the setting of bony erosion and lysis, cystic changes, and loss of bone stock. In this article, we describe first metatarsophalangeal distraction arthrodesis technique using tricortical calcaneus autograft with the aim of simplifying donor site graft harvesting and decreasing donor site morbidity while attaining successful osseous union...

We reviewed 33 consecutive Mau-Reverdin osteotomies in 23 patients performed for correction of hallux abducto valgus from November 2010 to May 2013. All patients were followed up and evaluated for a mean of 401 days and median of 360 days after surgery. In each foot, the preoperative first intermetatarsal angle, hallux abductus angle, and proximal articular set angle were obtained. The mean correction of these angles was as follows: intermetatarsal angle 10.5° ± 3.31°, hallux abductus angle 24.4° ± 8...

BACKGROUND: The foot is the main element of artistic creation in flamenco dancing. At the professional level, the foot undergoes high musculoskeletal demands, predisposing the development of podiatric pathologic disorders in this group. The principal objective of this study was to determine the most common foot lesions in professional female flamenco dancers. METHODS: In a cross-sectional observational study of 44 female professional flamenco dancers, the participants completed a short questionnaire about their demographic features, number of hours danced per week, and years of professional activity...

The present report describes a new method of hallux abducto valgus deformity correction planning using the mechanical axis of the medial column (mechanical axis planning). This method of radiographic evaluation identifies an ideal position for the first metatarsal after correction and is useful regardless of the surgical procedure chosen. We retrospectively reviewed 200 radiographs to identify a "normal" value for the mechanical axis angle. We reviewed 100 radiographs of patients with hallux abducto valgus deformity (deformity group) and 100 radiographs of patients without hallux abducto valgus deformity (control group)...

The chevron osteotomy is a popular procedure used for the correction of moderate hallux abducto valgus deformity. Fixation is typically accomplished with Kirschner wires or bone screws; however, in cystic or osteoporotic bone, these could be inadequate, resulting in displacement of the capital fragment. We propose using a locking plate and interfragmental screw for fixation of the chevron osteotomy that could reduce the healing time and decrease the incidence of displacement. We performed a retrospective cohort study for chevron osteotomies on 75 feet (73 patients)...

Hallux abducto valgus (HAV), one of the most common forefoot deformities, occurs primarily in elderly women. HAV is a complex disease without a clearly identifiable cause for its higher prevalence in women compared with men. Several studies have reported various skeletal parameters related to HAV. This study examined the geometry of the proximal phalanx of the hallux (PPH) as a potential etiologic factor in this deformity. A total of 43 cadaver feet (22 males and 21 females) were examined by means of cadaveric dissection...

REVIEW

Of the >100 procedures that have been proposed to treat hallux valgus or the "bunion" deformity, most have focused on correction through metatarsal osteotomies at various levels combined with soft tissue balancing procedures at the first metatarsophalangeal joint. This paradigm of metatarsal osteotomy and soft tissue balancing has been so commonplace, any argument for a fundamental change to the approach becomes uncomfortable and seems unwarranted to most foot and ankle surgeons. However, the simple fact that so many procedures exist, with so many modifications of these procedures, can be interpreted as a failure of our basic paradigm of metatarsal osteotomy and soft tissue balancing...

First ray function and hallux misalignment after isolated tibial sesamoidectomy have been topics of debate. Although sesamoidectomy has been proved to be effective in the relief of sesamoid pain, many foot and ankle surgeons remain hesitant to perform the procedure fearing a possible joint perturbation. To our knowledge, the present study is the first to evaluate both laboratory and clinical evidence of the association between isolated tibial sesamoidectomy and hallux abducto valgus deformity. The bench study consisted of 10 cadaveric limbs that were dissected and prepared for testing...

STATEMENT OF PURPOSE: Excessive pronation of the rearfoot has been implicated as a destabilizing force in the progression of hallux abducto valgus. Although the scarf bunionectomy has been shown to effectively correct the intermetatarsal angle associated with hallux valgus deformity, its effect on the rearfoot has yet to be established. The purpose of this case series is to demonstrate the effect of the scarf bunionectomy on rearfoot alignment. METHODOLOGY: Medical records were reviewed to isolate patients who underwent unilateral or bilateral scarf bunionectomies (with or without akin osteotomy) who had complete medical records, follow-up of at least 12 months, and met the inclusion/exclusion criteria...

Suzanne T Hawson
This article discusses physical therapy considerations after hallux valgus correction. Hallux valgus is a fairly common occurrence, and corrective surgery is an option when conservative measures fail. Symptoms such as pain, swelling, and difficulty walking may persist after surgical correction of bunion deformity that addresses soft tissue and bone structure. Physical therapy is helpful after corrective hallux valgus surgery to address impairments and continued dysfunction and to improve overall patient outcome expectations...

Jason Morris, Michael Ryan
Proximal first metatarsal osteotomies have historically been associated with and limited to treatment of severe hallux valgus deformities. These procedures are powerful in deformity correction and overall realignment of first ray function because of their ability to correct closer to the deformity's origin. When considering all factors in bunion correction, they are good options for correction of a wide range of hallux abducto valgus deformities. This article discusses the use of proximal metatarsal osteotomies for correction of hallux valgus deformity, techniques to facilitate optimal outcome, and common complications of these osteotomies...

The scarf osteotomy has been used and researched extensively for many years for the correction of hallux valgus deformity in both the adolescent and adult populations. It is an inherently stable construct, which allows for early weight bearing and early return to activities of daily living. The scarf procedure has a wide array of surgical indications with great reproducibility and a low complication rate, and it can be performed bilaterally simultaneously, with long-term predictability. Once the scarf procedure is mastered, it is a rewarding and predictable operation for both the surgeon and patient...

REVIEW
L Mae Chandler
An array of distal first metatarsal osteotomies has been described over the decades for the correction of hallux valgus. No one procedure is proficient in correcting all forms and severities of hallux valgus deformities. To optimize results, it is imperative for the surgeon to match a procedure and its modifications to the patient's deformity. The dorsal long arm chevron osteotomy stands at the forefront for correction of mild to moderate hallux abductovalgus. The results with this specific osteotomy are predictable; it allows for early ambulation, and it is easily modified to compensate for the deformity at hand...

It is well known that the pathologic positions of the hallux and the first metatarsal in a bunion deformity are multiplanar. It is not universally understood whether the pathologic changes in the hallux or first metatarsal drive the deformity. We have observed that frontal plane rotation of the hallux can result in concurrent positional changes proximally in the first metatarsal in hallux abducto valgus. In the present study, we observed the changes in common radiographic measurements used to evaluate a bunion deformity in 5 fresh frozen cadaveric limbs...

We observed the changes in the angular measurements commonly used in the evaluation of the first metatarsal and first metatarsophalangeal joint in cadaveric specimens before and after frontal plane rotation of the first metatarsal. Measurements of the first and second intermetatarsal angle (IMA), hallux abductus angle, proximal articular set angle, and tibial sesamoid position (TSP) were taken after varying degrees of varus and valgus rotation of the first metatarsal. Standard dorsoplantar radiographs were taken at 0°, 10°, 20°, and 30° of valgus rotation of the first metatarsal and repeated at 10°, 20°, and 30° varus rotation of the first metatarsal...

Evolution of the terminology applied to the bunion deformity has progressed in parallel with our changing understanding of the deformity itself. Along this path of progression have been multiple terms, sometimes with multiple meanings. Hallux valgus and metatarsus primus varus are 2 of the most common terms for the deformity. Although commonly used, these descriptors can have multiple meanings, and inconsistencies in interpretation can lead to confusion. We propose a more detailed terminology to provide a more accurate description of the entire bunion deformity in 3 planes and for both the hallux and the metatarsal component of the deformity...

We present a radiographic review of 94 patients who underwent first metatarsophalangeal joint arthrodesis. The main focus of our review was to assess the change in the intermetatarsal angle (IMA). The change in the IMA was measured for the entire group and for 2 subgroups (IMA 11° to 15° and IMA >15°). The results of the angular measurements for the total data set were as follows: mean preoperative first IMA, 15.32° (range 11° to 24°), mean postoperative IMA, 9.88° (range 3° to 18°), and mean change in IMA of 5...
