The pathomechanics for the development of the hallux valgus deformity takes place at the first metatarsophalangeal joint-the sesamoid complex. The sesamoid complex consists of seven muscles, eight ligaments, and two sesamoid bones. When the first metatarsal escapes the complex and drifts medially, the sesamoids remain twisted in situ, several of the ligaments “fail,” and others contract. The authors propose reduction of the metatarsus primus varus by first metatarsal osteotomy and appropriate ligament releases and plications to restore alignment. A detailed understanding of the pathomechanics is essential for proper interpretation of the problems and anticipated lasting surgeries.

Today, bunion surgery is still controversial. Considering that a bunion deformity in fact may be a result of multiple causes, the rationale of the currently applied techniques of surgical treatment has not been conclusively demonstrated. In view of the known hypermobility syndrome of the first ray that results in insufficient weightbearing beneath the first metatarsal head, the relationship between this syndrome and hallux valgus deformity has been investigated. The results suggest a direct relationship between painful hallux valgus deformity and hypermobility in extension of the first tarsometatarsal joint. A pathological mechanism of symptomatic hallux valgus is proposed that relates this pathology with primary weightbearing disturbances in the forefoot where angulation of the first metatarsophalangeal joint is one of the consequences. The alignment of the metatarsal heads within the sagittal plane seems to be a main concern in many hallux valgus deformities. As a consequence, treatment includes reestablishing stable sagittal alignment in addition to the horizontal reposition of the metatarsal over the sesamoid complex. As an example, first tarsometatarsal reorientation arthrodesis regulates the elasticity of the multiarticular first ray within the sagittal plane and may be the treatment of choice in many hallux valgus deformities.

One hundred seventy-two patients who underwent surgical correction of hallux valgus deformity were evaluated. The procedures chosen were: first metatarsal osteotomy in 96, Keller procedure in 42, metatarsophalangeal arthrodesis in 25, and simple bunionectomy in 9. This study allowed the establishment of the following guidelines for surgery. 1) Osteotomy alone yields a satisfactory result in patients under the age of 50 years who have minimal osteoarthritis of the metatarsophalangeal joint. 2) The Keller procedure is suggested in patients over the age of 50 who have significant osteoarthritis. 3) Metatarsophalangeal fusion is suggested in patients under the age of 50 with significant osteoarthritis. 4) Simple bunionectomy revealed poor results in the majority of patients. It should be reserved for the elderly patient with an infected bunion.

This paper describes a simple technique of oblique osteotomy of the first metatarsal for treatment of symptomatic hallux valgus deformity. The osteotomy is performed at a 30° angle from the long axis of the metatarsal shaft. The head of the metatarsal is then displaced laterally to provide correction of the hallux valgus. This is an uncomplicated procedure for the treatment of hallux valgus. From 1984 through 1989, 53 feet in 31 patients were treated with an oblique osteotomy of the first metatarsal. A total of 49 feet in 27 patients were followed up more than 2 years. The follow-up x-rays and clinical examinations revealed a good result in 43 feet. In six feet of three patients, all of whom had simultaneous oblique osteotomies of both the first and second metatarsals, a fair or poor result was obtained. It was learned that oblique osteotomy for hallux valgus greater than 40° provided insufficient correction of the valgus angle or limitation of motion at the metatarsophalangeal joint of the great toe.

Background The purpose of the study was to preoperatively evaluate the demographics, etiology, and radiographic findings associated with moderate and severe hallux valgus deformities in adult patients (over 20 years of age) treated operatively over a 33-month period in a single surgeon's practice. Methods Patients treated for a hallux valgus deformity between September, 1999, and May, 2002, were identified. Patients who had mild deformities (hallux valgus angle < 20 degrees), concurrent degenerative arthritis of the first metatarsophalangeal joint, inflammatory arthritis, recurrent deformities, or congruent deformities were excluded. When enrolled, all patients filled out a standardized questionnaire and had a routine examination that included standard radiographs, range of motion testing, and first ray mobility measurement. A chart review and evaluation of preoperative radiographs were completed on all eligible patients. Results One-hundred and three of 108 (96%) patients (122 feet) with a diagnosis of moderate or severe hallux valgus (hallux valgus angle of 20 degrees or more) 70 qualified for the study. The onset of the hallux valgus deformity peaked during the third decade although the distribution of occurrence was almost equal from the second through fifth decades. Twenty-eight of 122 feet (23%) developed a deformity at an age of 20 years or younger. Eighty-six (83%) of patients had a positive family history for hallux valgus deformities and 87 (84%) patients had bilateral bunions. 15% of patients in the present series had moderate or severe pes planus based on a positive Harris mat study. Only 11% (14 feet) had evidence of an Achilles or gastrocnemius tendon contracture. Radiographic analysis found that 86 of 122 feet (71%) had an oval or curved metatarsophalangeal joint. Thirty-nine feet (32%) had moderate or severe metatarsus adductus. A long first metatarsal was common in patients with hallux valgus (110 of 122 feet; 71%); the mean increased length of the first metatarsal when compared to the second was 2.4 mm. While uncommon, the incidence of an os intermetatarsum was 7% and a proximal first metatarsal facet was 7%. The mean preoperative first ray mobility as measured with Klaue's device was 7.2 mm. 16 of 22 (13%) feet were observed to have increased first ray mobility before surgery. Conclusions 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).

Hallux valgus is characterized by the appearance and growth of a painful “lump” in the region of the first metatarsophalangeal joint, the development of forefoot corns, and inability to choose the right shoes, which leads to a significant decrease in the quality of life of these patients. Corrective osteotomies that preserve the metatarsophalangeal joint, for example Austin (Chevron) osteotomy, are usually used for hallux valgus deformity of the I, II degrees. Radiography with the study of the hallux valgus angle (HVA), the intermetatarsal angle (IMA), the distal metatarsal articular angle (DMAA) is a research method that shows the true correlation between bone structures. The correlation between the radiological and functional indicators of osteotomy allows us to determine possible recommendations for indications for surgical treatment of Hallux valgus. Correlation shows that the largest correction of hallux valgus in older patients occurs due to a small adjustment of the angle of DMMA and HVA. IMA had the best correction after Austin osteotomy among patients of a younger age, then the HVA, and the DMMA had minimum correction according to the AOFAS rating scale (Kitaoka). The revealed correlations allow us to determine the correct tactics for the treatment of hallux valgus by identifying the benefits of Austin osteotomy.

We present the short-term follow-up of 55 symptomatic hallux valgus deformities in 38 patients, treated operatively with a modification of the spike distal first metatarsal osteotomy, as described by Gibson and Piggott in 1962. The age range of the patients was 17 to 72 years at the time of surgery. The postoperative follow-up period was 12 to 55 months. Excellent and good clinical and radiographic results were recorded in 96.2% of our patients. Two of the patients (3.8%) were dissatisfied; one of them complained of metatarsalgia after the procedure, and the other had stiffness of the metatarsophalangeal joint and metatarsalgia that had been present before surgery. Three others (5.45%) required revision after early postoperative displacement but were asymptomatic subsequently. We concluded that our technique is an effective method of treating mild hallux valgus deformities with the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal tilting of the distal fragment. Hallux valgus (lateral deviation of the great toe) is not a single disorder, as the name implies, but a complex deformity of the first ray that sometimes may involve the lesser toes. More than 130 procedures exist for the surgical correction of hallux valgus, which means that no treatment is unique. No single operation is effective for all bunions. 5 , 22 , 29 The objectives of surgical treatment are to reduce pain, to restore articular congruency, and to narrow the forefoot without impairing function, by transferring weight to the lesser metatarsals either by shortening or by dorsal tilting of the first metatarsal. 5 , 19 , 24 , 27 Patient selection is important for a satisfactory outcome after surgery of any kind, and our criteria were age, degree of deformity, presence of arthrosis, and subluxation of the first metatarsophalangeal joint. 1 , 5 , 13 , 19 – 21 , 24 , 29 In this study, we present a new method of treating hallux valgus that has been used at Mayday University Hospital since 1990. The technique was first described at the British Orthopaedic Foot Surgery Society, Liverpool, November 1990, 7 and we now present the short-term follow-up results. The procedure is essentially a modification of the spike osteotomy of the neck of the first metatarsal, as described by Gibson and Piggott. 9 It has the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal displacement of the distal fragment.

Background: We aimed to compare the postoperative height of the second metatarsal head relative to the first metatarsal head using axial radiographs among 3 different commonly used osteotomy techniques: proximal chevron metatarsal osteotomy (PCMO), scarf osteotomy, and distal chevron metatarsal osteotomy (DCMO). Methods: We retrospectively reviewed the radiographs and clinical findings of the patients with painful callosities under the second metatarsal head, complicated by hallux valgus, who underwent isolated PCMO, scarf osteotomy, or DCMO from February 2005 to January 2015. Each osteotomy was performed with 20 degrees of plantar ward obliquity. Along with lateral translation and rotation of the distal fragment to correct the deformity, lowering of the first metatarsal head was made by virtue of the oblique metatarsal osteotomy. Results: Significant postoperative change in the second metatarsal height was observed on axial radiographs in all groups; this value was greatest in the PCMO group (vs scarf: P = .013; vs DCMO: P = .008) but did not significantly differ between the scarf and DCMO groups ( P = .785). The power for second metatarsal height correction was significantly greater in the PCMO group (vs scarf: P = .0005; vs DCMO: P = .0005) but did not significantly differ between the scarf and DCMO groups ( P = .832). Conclusions: Among the 3 osteotomy techniques commonly used to correct hallux valgus deformity, we observed that PCMO yielded the most effective height change of the second metatarsal head. Level of Evidence: Level III, retrospective comparative series.

Sesamoidectomy of the first metatarsophalangeal joint in athletically active patients may be indicated in cases of chronic sesamoiditis resistant to nonsurgical care or symptomatic displaced fractures or nonunion. Painful scar, hallux deviation, and delayed return to activity are all potential complications. These need to be considered especially when performing surgery in the athletically active individual. Twenty-six sesamoidectomies in 24 patients (21 females and 3 males) were reviewed for type of sesamoidectomy, incision location, time to return to activity, and complications. Mean age was 35.4 years (range, 16–68 years) with mean follow-up 86.4 months. Eleven athletes (defined as professional or varsity level sports) operated on had a mean return to activity of 7.5 weeks (range, 4–10 weeks), while 13 “active” patients had a mean return to activity of 12.0 weeks. This difference was statistically significant using the t-test, ( p <.02). There were 10 fibular and 16 tibial sesamoids excised. Complications included one hallux varus and two cases of postoperative scarring with neuroma-like symptoms, all associated with fibular sesamoidectomy; there was one case of hallux valgus deformity with tibial sesamoidectomy. Despite the functional importance of tibial and fibular sesamoids, athletically active individuals can return to sports after a sesamoidectomy as early as 7.5 weeks.

The modified McBride technique is widely used in bunion surgery. The aim of this report is to analyze the influence that transferring the adductor hallucis tendon had on the first intermetatarsal angle (IMA), hallux abductus angle (HAA), and tibial sesamoid position (TSP) when used to correct the hallux valgus deformity. A prospective study was conducted of 31 hallux abducto valgus patients. A modified McBride procedure was performed to repair the deformity. In 16 patients (group 1), the adductor tendon was transferred, and in 15 (group 2), it was not. The tendon transfer was at random. The preoperative and postoperative variables IMA, HAA, and TSP were measured and analyzed by means of univariate and multivariate statistics. In group 1, the preoperative values of the first IMA and the HAA averaged 13.5° and 30°, respectively, decreasing postoperatively to 10.3° and 10.7°. In group 2, the corresponding preoperative angles were 12.9° and 25.6°, and the postoperative angles were 9.7° and 10°. There were no statistically significant differences between the 2 groups in the correction of the IMA, HAA, and TSP. As measured by the aforementioned radiographic measurements, there is no advantage in transferring the adductor hallucis tendon to the first metatarsophalangeal joint capsule in the correction of hallux valgus
