Chevron osteotomy for hallux valgus--SGH experience.

Thirty-one chevron osteotomies for hallux valgus performed over a period of four years were reviewed. Their follow-up period ranged from one to five years. All the patients had pain over the bunion prior to operation. After operation, there was marked decrease of pain over the first matatarsophalangeal joint. The preoperative hallux valgus angle average 27 degrees and the postoperative angle averaged 12 degrees. The preoperative intermetatarsal angle averaged 13 degrees and the postoperative angle, 8 degrees. Ninety-one per cent of the patients were satisfied with the result of the procedure.

Silastic implant arthroplasty with proximal metatarsal osteotomy for painful hallux valgus.

First metatarsophalangeal joint arthrosis may be associated with hallux valgus deformity. In an attempt to address the pain and deformities of this disorder, silastic implant arthroplasty combined with soft tissue balancing and proximal first metatarsal osteotomy has been performed on 17 feet in 11 patients. A retrospective review of the results at an average followup of 29.5 months is presented. Subjective pain relief has been satisfactory, and loss of correction of deformity has been minimal. Infection remains as a significant postoperative complication. This technique may be a treatment option in the low demand patient with a hallux valgus deformity, painful arthritis of the first metatarsophalangeal joint, and a wide first intermetatarsal angle.

Influence of metatarsal head displacement on metatarsal pressure distribution after hallux valgus surgery.

We reviewed 63 feet after plain subcapital osteotomy for simultaneous correction of hallux valgus and metatarsus primus varus. Results were evaluated clinically and by radiographs and force plate measurements. Eighty-three percent of the patients were satisfied with their surgery. The hallux valgus angle was improved by 9.3 degrees and the intermetatarsal angle by 6 degrees. The osteotomy resulted in a displacement of the metatarsal head in the lateral direction (10 mm) and in the plantar direction (11.3 mm). Normalization of the load distribution on the metatarsal head was achieved in the group with 11 to 15 mm of plantar displacement. Based on our results, we recommend plain subcapital osteotomy for hallux valgus deformities with moderate metatarsus primus varus. After correction of the intermetatarsal angle and sufficient plantar displacement a physiological distribution of load on the metatarsal head can be expected.

Percutaneous distal metatarsal osteotomy for correction of hallux valgus. Surgical technique.

BACKGROUND: Distal osteotomy of the first metatarsal is indicated for the surgical treatment of mild-to-moderate hallux valgus deformity. The aim of this study was to evaluate the results of a subcapital distal osteotomy of the first metatarsal with use of a percutaneous technique. METHODS: From 1996 to 2001, 118 consecutive percutaneous distal osteotomies of the first metatarsal were performed for the treatment of painful mild-to-moderate hallux valgus in eighty-two patients. The patients were assessed with a clinical and radiographic protocol at a mean of 35.9 months postoperatively. The American Orthopaedic Foot and Ankle Society (AOFAS) hallux-metatarsophalangeal-interphalangeal scale was used for the clinical assessment. RESULTS: The patients were satisfied following 107 (91%) of the 118 procedures. The mean score on the AOFAS scale was 88.2 +/- 12.9 points. The postoperative radiographic assessments showed a significant change (p < 0.05), compared with the preoperative values, in the mean hallux valgus angle, first intermetatarsal angle, distal metatarsal articular angle, and sesamoid position. The valgus deformity recurred after three procedures (2.5%), the first metatarsophalangeal joint was stiff but not painful after eight (6.8%), and a deep infection developed after one (0.8%). The infection resolved with antibiotic therapy. CONCLUSIONS: The percutaneous technique proved to be reliable for the correct execution of a distal linear osteotomy of the first metatarsal for the correction of a painful mild-to-moderate hallux valgus deformity. The clinical results appear to be comparable with those obtainable with traditional open techniques, with the additional advantages of a minimally invasive procedure, a substantially shorter operating time, and a reduced risk of complications related to surgical exposure.

Treatment of hallux valgus by oblique osteotomy of the first metatarsal.

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 degree 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 degrees provided insufficient correction of the valgus angle or limitation of motion at the metatarsophalangeal joint of the great toe.

Clinical, quantitative assessment of first tarsometatarsal mobility in the sagittal plane and its relation to hallux valgus deformity.

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.

The SCARF osteotomy for the correction of hallux valgus deformities.

The authors report their experience with a modified SCARF osteotomy with three years follow-up. Correction of moderate to severe hallux valgus deformities was achieved using a Z step osteotomy cut to realign the first metatarsal bone. A retrospective analysis was undertaken in 89 consecutive patients (111 feet). Results were analyzed by clinical examination, a questionnaire including the AOFAS forefoot score, and plain roentgenograms. Hallux valgus and intermetatarsal angle improved at mean 19.1 degrees and 6.6 degrees, respectively. Mean forefoot score improved from 50.1 to 91 points out of 100 possible points. Satisfactory healing time was expressed by an average return back to work of 5.8 weeks and back to sport of 8.3 weeks. Persistence or recurrence of hallux valgus was seen in seven patients (6%). The complication rate was 5.4% including superficial wound infection, traumatic dislocation of the distal fragment, and hallux limitus. The presented technique provides predictable correction of moderate to severe hallux valgus deformities.

The spike osteotomy for hallux valgus: a clinical and radiological evaluation.

A distal metatarsal osteotomy with soft tissue correction is a frequently performed operation to correct mild to moderate hallux valgus deformity. This is a prospective study of 28 feet in 25 patients who underwent spike osteotomy of the first metatarsal with medial capsulorraphy for symptomatic hallux valgus. The osteotomy is a distal metatarsal osteotomy with a spike fashioned in the plantar and lateral quarter of the proximal fragment and impacted into the trough created in the center of the distal fragment, providing lateral and plantar shift of the distal fragment. The American Orthopaedic Foot and Ankle Society's rating scale was used for functional assessment, and a visual analog scale gauged pain. The average follow-up was 27 months. The rating scale score improved from a mean preoperative value of 39/100 to 84/100. Twenty-six feet had complete pain relief, whereas 2 feet had a lesser degree of persistent metatarsalgia. A review of preoperative and postoperative radiographs showed that the hallux valgus angle improved from a mean 36 degrees preoperatively to 18 degrees postoperatively. Likewise, the mean 1 to 2 intermetatarsal angle improved from 13 degrees to 7.3 degrees. There was no incidence of avascular necrosis. Fourteen patients (16 feet) rated the outcome as excellent, 10 (11 feet) as good, and 1 patient with asymptomatic mild hallux varus deformity rated the result as fair. These results demonstrate that the spike osteotomy is a suitable operation for treatment of mild to moderate hallux valgus.

Hypermobility in hallux valgus.

Hypermobility has been implicated as one of the etiological components in common foot problems such as hallux valgus but has not been substantiated by experimental data. Twenty patients with symptomatic untreated hallux valgus and 20 controls were evaluated with a simple hypermobility scoring system. A statistically significant correlation was found to reveal that female patients aged 20 to 40 yr with symptomatic hallux valgus have a mild generalized hypermobility when compared to a similar group of control patients. The presence of such ligamentous laxity would seem to support the need for bony correction in such patients as soft tissue procedures would have a greater propensity for malalignment due to the underlying hypermobility in combination with everyday environmental stresses of trauma and overuse.

Moderate to severe hallux valgus deformity: correction with proximal crescentic osteotomy and distal soft-tissue release.

Between 1991 and 1995, 96 patients (114 feet) were treated with a proximal crescentic metatarsal osteotomy and distal soft-tissue procedure for moderate to severe hallux valgus deformity [intermetatarsal (IM) angle > 15 degrees, or hallux valgus (HV) angle > 30 degrees]. At an average follow-up of 26 months, 8 men and 62 women (86 feet) with a mean age of 53.2 years were retrospectively reviewed. The HV angle averaged 41.1 degrees preoperatively and 14.6 degrees postoperatively. The respective values for the IM angle were 17.8 degrees and 7.8 degrees. Neither the average metatarsal shortening of 3 mm nor the dorsal angulation at the osteotomy site seen in 9% of cases evidenced any clinical significance at follow-up. Patient satisfaction was excellent or good in 91%, and the mean Mayo Clinic Forefoot Score (total 75 points) improved from 37.2 to 61.1 points. Complications included 8 cases of hallux varus and 5 cases of hardware failure. Based on this first study exclusively focusing on moderate to severe hallux valgus deformity, we conclude that proximal first metatarsal osteotomy in combination with a lateral soft-tissue procedure is effective in correcting moderate to severe symptomatic hallux valgus deformity with metatarsus primus varus (IM angle > 15 degrees or HV angle > 30 degrees).

Surgical treatment of severe hallux valgus: the state of practice among academic foot and ankle surgeons.

BACKGROUND: The purpose of this study was to evaluate the operative procedures used for treatment of severe hallux valgus by academic foot and ankle surgeons practicing in the United States. METHODS: A patient with severe hallux valgus deformity was developed as a hypothetical case: a 50-year-old woman with a severe deformity (intermetatarsal angle = 20 degrees; hallux valgus angle = 42 degrees). The patient was symptomatic with pain, did not improve with conservative measures, and wanted the deformity corrected. This case was sent to academic foot and ankle surgeons in a survey to determine their preferred operative treatment for this case. The overall response rate was 84% (128 of 153). To be included in the study group each surgeon had to have 1) foot and ankle patients comprising 50% or more of his clinical practice and 2) direct responsibility for teaching orthopaedic residents. One hundred and five respondents met the inclusion criteria and formed the study group; however, three surveys with invalid responses were deleted. RESULTS: Fifty-two percent (54 of 102) of the respondents chose a metatarsal osteotomy, 26% (26 of 102) a first metatarsophalangeal (MTP) joint arthrodesis, and 24% (24 of 102) a Lapidus procedure. Two respondents chose both an arthrodesis and a metatarsal osteotomy. Among the 54 respondents who chose metatarsal osteotomies, 24 used a Ludloff, 16 a proximal crescentic, eight a proximal chevron, two a scarf, two a distal chevron, and two other. In addition, secondary procedures to enhance the correction included a Weil osteotomy in 46% (47 of 102) and an Akin osteotomy in 30% (31 of 102). CONCLUSIONS: There was a wide variation in the type of procedure used to correct this severe hallux valgus deformity; approximately 50% of the respondents chose a metatarsal osteotomy, 25% chose a first MTP joint arthrodesis, and 25% a Lapidus procedure.

Clinical and biomechanical risk factors of patients diagnosed with hallux valgus.

The purpose of this study was to identify the clinical and plantar loading variables related to hallux valgus. Fifty-one healthy control subjects and 40 subjects with a diagnosis of moderate hallux valgus deformity of similar age and body weight were recruited for this study. Clinical measurements of pain, first metatarsophalangeal joint range of motion, and single-leg resting calcaneal stance position were obtained. Biomechanical measurements were obtained using a capacitive pressure platform. Plantar loading variables were calculated for seven regions of the plantar surface. A univariate analysis followed by a stepwise logistic regression was used to analyze the data. The results indicated that high values for pain, single-leg resting calcaneal stance position, hallux region peak pressure and force-time integral, and central forefoot region force-time integral increased the likelihood of hallux valgus.

Wilson shaft osteotomy for hallux valgus.

The results of a modified Wilson shaft osteotomy for hallux valgus in 77 feet of 51 patients were excellent or good in 62 feet after 2 to 4 years. The correction of the hallux valgus angle and intermetatarsal angle was excellent or good in 69 feet. The operation is technically simple provided dorsal angulation of the distal fragment is avoided in the early postoperative period.

Insertion of the abductor hallucis muscle in feet with and without hallux valgus.

Textbooks of human anatomy present different opinions on the insertion of the abductor hallucis muscle which is concerned in etiology as well as in therapy of hallux valgus. In plastic and reconstructive surgery the muscle is taken as a graft for flap-surgery. In this study 109 feet (58 right, 51 left) were examined, 18 of these with clinical hallux valgus. The tendon of the muscle may attach to the tendon of the medial head of the short flexor hallucis muscle where a subtendineous bursa can be found. At the head of the first metatarsal bone the joint capsule is reinforced by fibres arising from the medial sesamoid bone which may be called "medial sesamoidal ligament." The tendon passes the first metatarsophalangeal joint plantarily to its transverse axis. Three types of insertion could be distinguished: type A, insertion at the proximal phalanx (N = 42); type B, insertion at the medial sesamoid ligament and at the medial sesamoid bone (N = 65); type C, insertion at the medial sesamoid bone (N = 2). In all types superficial fibres of the tendon extended to the medial and plantar sides of the base of the proximal phalanx, running in a plantar to dorsal direction. Statistical analysis exposed neither significant differences between both sides nor significant difference between normal feet and feet with hallux valgus. Therefore, a specific pattern of insertion of the abductor hallucis muscle in hallux valgus cannot be stated.

[Surgical treatment of recurrent hallux valgus].

PURPOSE OF THE STUDY: Little work has been reported on the treatment of recurrent hallux valgus. We reviewed 64 cases after surgical treatment in order to ascertain the cause of recurrence, results of the treatment given, and deduce therapeutic options and indications. MATERIAL AND METHODS: Fifty-nine patients had 64 recurrent hallux valgus bunions. Mean age of the patients was 58 years, 54 women and 5 men. The clinical and radiographic preoperative work-up led to two categories of treatments. In 35 cases, conservative treatment was used to re-align the axis by procedures on the soft tissues either alone or in combination with MacBride tendon transfers, metatarsal osteotomies, or osteotomies to shorten the first phalange. In 29 cases, metatarsophalangeal arthrodesis was used. Patient satisfaction, pain, deformation, shoe wearing and activity were recorded at follow-up. The same radiological parameters were used postoperatively to assess anatomic results. RESULTS: Mean follow-up was more than 6 years (range 2-18 years). The subjective result was good in 52 cases. The objective result was good in 50 cases and poor in 14 (including 7 cases with insufficient correction). The results were analyzed by type of treatment. DISCUSSION: The preoperative analysis demonstrated that recurrence is due to insufficient initial treatment which must take into account all the components leading to the deformation. Arthrodesis gave a good result in 83% of the cases and conservative treatment gave a good result in 71%. Thus, in our opinion, no one type of treatment of recurrent hallux valgus can be applied for all patients. Nevertheless, conservative treatment should associate complementary procedures that can be deduced from the clinical and radiological analysis.

[Restorative surgery of the ligament apparatus of the metatarsal-phalangeal joint and metatarsus in hallux valgus].

The new operation method of 'hallux valgus' after Boriss Tserliuk is described. The innovation consists in creation of an artificial medial metatarsal ligament and bringing tarsal bones closely together. Thus the first finger is fixed in right position and tarsal sesamoid complex is recovered. The methods of metatarsal and intertarsal angles' measurements are described. The results of 40 operations in 30 cases (27 females and 3 males) are presented. The functional and cosmetic results are positive.

[Metatarsal osteotomies for hallux valgus].

In the surgical treatment of hallux valgus, proximal, diaphyseal, and distal osteotomies of the first metatarsal bone are commonly used. In an overview article different procedures are described as well as our own stage-adapted concept. Deformities with congruent articulation of the metatarsophalangeal joint are successfully treated with a distal chevron osteotomy. In an incongruent joint a distal soft tissue procedure is required for reduction of the joint. The metatarsus varus displacement is corrected with a proximal osteotomy of the first metatarsal bone. The indications and details of the surgical techniques are described as well as postoperative treatment, results, and possible complications.

Comparison of two proximal osteotomies for the treatment of hallux valgus.

Moderate to severe deformities of hallux valgus can be corrected with combination procedures, such as a proximal crescentic metatarsal osteotomy and a distal soft tissue procedure. Because crescentic osteotomy allows for motion in all planes, inadvertent metatarsal elevation can result in metatarsalgia. The crescentic shelf osteotomy (CSO) provides a plantar shelf, decreasing the complication of dorsiflexion fixation. Eighteen polyurethane foam specimens in three groups were prepared and tested to failure on a servohydraulic Instron testing machine. The mechanical characteristics of stiffness, deformation, ultimate failure load, and stored energy were compared between single-screw fixation crescentic osteotomies and single- and dual-screw CSOs in molded polyurethane foam metatarsal sawbones. In addition, 12 cadaver specimens were randomly divided, and a CSO or crescentic osteotomy was performed. Preosteotomy and postosteotomy intermetatarsal, dorsiflexion, and pronation angles were compared from radiograph measurements. The results showed comparable mechanical characteristics among the groups, as measured by the area under the curve (P=0.95), ultimate failure load (P=0.35), deformation (P=0.63), and stiffness (P=0.21). Greater improvements were seen in the CSO group compared with the crescentic osteotomy group in correction of the intermetatarsal angle (4.8 degrees compared with 3.2 degrees) and of the first metatarsal plantarflexion (2.3 degrees compared with 3.2 degrees of dorsiflexion). However, these differences were insignificant (P=0.10 and P=0.41) with the numbers available. Compared with the crescentic osteotomy, a CSO may possibly provide easier initial fixation but similar mechanical properties.
