Chevron osteotomy of the first metatarsal for hallux valgus

A retrospective study of 50 chevron osteotomies evaluated subjective and objective functional and cosmetic results, which were in keeping with other reported studies--i.e. satisfactory subjective cosmesis in 98%; excellent or good pain relief in 84%; and satisfactory objective cosmesis in 84%. The correction of the 1st intermetatarsal angle averaged 3.3 degrees, and that of the metatarsophalangeal valgus averaged 15 degrees. Average active range of motion of the 1st metatarsophalangeal joint was 60 degrees. Complications were generally mild and asymptomatic, and were usually iatrogenic. The findings of this study, together with information gained from a concomitant stress analysis, led to recommendations regarding operative technique.     

The distal metatarsal osteotomy for the treatment of hallux valgus

This article discusses various forms of distal metatarsal osteotomy for the treatment of hallux valgus. The techniques for the various osteotomies have evolved over the years to allow the surgeon to match a procedure and its modifications to the individual patient's deformity, thus optimizing outcomes. Fixation techniques continue to evolve, and meticulous surgical technique to prevent complications remains a must. Regardless of the osteotomy used, the authors believe that adherence to the techniques laid out in current literature will provide gratifying results for the surgeon and the patient.

The Scarf first metatarsal osteotomy in the correction of hallux valgus deformity

The correction of hallux valgus has been dramatically improved by the scarf 1^st metatarsal osteotomy, which brings great versatility for covering all the indications. Its strong fixation allows an early functional recovery; the long-term follow-up confirms the reliability of this procedure, which can be combined with other osteotomies and soft tissue procedures. However, the surgeon has to determine pre and intraoperatively the correction that has to be applied; this technique is not difficult but has to be performed accurately. This is the interest of this article, which emphasizes the technical features that have to be applied.     

Distal metatarsal osteotomy for hallux valgus

Distal osteotomy of the first metatarsal with a step lateral displacement has been used in the treatment of 34 feet with hallux valgus.Stability of the osteotomy is achieved by a dorsomedial capsulorrhaphy. Suturing through drilled holes or internal fixation were not necessary. One case was complicated by dorsal tilt of the head of the metatarsal bone and required revision.

The assessment of adolescent hallux valgus before and after first metatarsal osteotomy

Summary A comprehensive method of evaluating the feet of patients with adolescent hallux valgus both before and after surgical correction is described. Serial clinical, photographic and radiological studies were made and a dynamic assessment of gait was carried out using a load-sensitive walkway. Observations were made on 36 feet in which hallux valgus was treated by a modification of the Wilson oblique metatarsal osteotomy, with removal of a wedge of bone and screw fixation. In the first six months after operation, there was a lateral shift of the weight-bearing pattern in the forefoot and less weight was taken on the toes, but there was a tendency to return to the pre-operative distribution of weight during the next four years. Persistence of the lateral shift of weight-bearing appeared to result from elevation of the first metatarsal head secondary to shortening of the first metatarsal during the osteotomy. This can be avoided by deliberate depression of the first metatarsal head at the time of operation and fixation of the fragments in the required position with a screw.

Résumé Les auteurs décrivent une méthode d'évaluation globale du pied, tant avant qu'après correction chirurgicale, chez des adolescents porteurs d'hallux valgus. Elle nécessite une série d'études des caractéristiques cliniques, photographiques et radiologiques, ainsi qu'une évaluation dynamique de la marche à l'aide d'un plateau de force. Cette méthode a été utilisée pour estimer avec exactitude les modifications survenues sur 36 pieds après que l'hallux valgus ait été traité par une variante de l'ostéotomie oblique du premier métatarsien décrite par Wilson, qui consiste en une résection d'un coin osseux suivie de fixation par une vis. Durant les six premiers mois post-opératoires, on note un déplacement de l'appui de l'avant-pied vers le dehors et une diminution de la charge au niveau des orteils, mais il y a une tendance à revenir à la répartition pré-opératoire de l'appui au cours des quatre années suivantes. La persistance du déplacement externe de l'appui semble résulter de la surélevation de la tête du premier métatarsien, conséquence du raccourcissement de cet os créé par l'ostéotomie. Ceci peut être évité en abaissant délibérément la première tête métatarsienne lors de l'opération et en fixant les fragments par une vis dans la position désirée.

     

Long-term results of the retrocapital metatarsal percutaneous osteotomy for hallux valgus

Purpose

The current trend in hallux valgus surgery is directed toward percutaneous procedures. However, no evidence that any of these methods of treatment are superior to the others has been described, excepting studies in the long term. The aim of this study was to analyse a series of patients who had undergone a percutaneous distal retrocapital osteotomy of the first metatarsal, and had been followed up for ten years.

Methods

We carried out a clinical and radiological evaluation of 115 feet ten years after surgery.

Results

The AOFAS scale results in the tenth postoperative year remained significantly favourable compared to their corresponding values in the preoperative period, yielding an improvement of 42.2 points overall on average. In relation to radiological findings, the mean hallux angle was maintained below 20 °, with a mean intermetatarsal angle of 8.1 °.

Conclusion

Percutaneous retrocapital metatarsal osteotomy for treatment of mild to moderate hallux valgus is effective in the long term, with the advantages of a minimally invasive procedure.     

The modified Mayo procedure combined with basal valgus osteotomy of the first metatarsal for severe hallux valgus

Summary The modified Mayo procedure corrects valgus deformity of the great toe secondary to osteoarthritis in the first metatarsophalangeal joint. Basal osteotomy of the first metatarsal to correct metatarsus primus varus and to maintain correction of the valgus deformity may be performed simultaneously. We retrospectively reviewed the results in 55 of 70 feet treated by this combined procedure. The average duration of follow-up was 4.2 years (range 0.5–6 years) and the average age at operation was 63 years (range 45–80 years). The results were either very good or good in 82%, moderate in 14%, and poor in 4%. Our technique of basal osteotomy of the first metatarsal is a simple and effective procedure to correct metatarsus primus varus and may restore the distal transverse arch. It should be considered as a possible method of treatment when the intermetatarsal angle is greater than 10°.     

Osteotomy of the base of the first metatarsal bone in the treatment of hallux valgus]

Authors performed in 1979 through 1991 in the Orthopaedic Department of the Semmelweis University of Medicine 47 osteotomies on the base of the first metatarsal bone in 37 patients. After the operation the intermetatarsal angle was in average under 10 and the metatarsophalangeal angle under 20 degrees. In chosen cases and with careful surgical technique good result can be obtained from the osteotomy of the base of the first metatarsal bone. The technique is not complicated, the osteotomy is healed quickly and well and the internal fixation makes early mobilization possible. It can and should be carried out in cases in which the intermetatarsal angle exceeds 10 degrees. After its performance, if necessary, operation beside the metatarsophalangeal joint may also be carried out.     

The surgical treatment of hallux valgus using distal metatarsal osteotomy and stabilization with a hallux splint. Preliminary results

The preliminary results of the surgical treatment of hallux valgus using subcapitate chevron-type osteotomy of the 1st metatarsal modified using a dynamic interfragmentary device are reported. The method satisfies the need to restore angular metatarsophalangeal and intermetatarsal values and improves metatarsal pain caused by hallux valgus correction, which influences the cosmetic results.

Distal metatarsal osteotomy for adolescent hallux valgus

This is a review of 55 metatarsal osteotomies for hallux valgus and metatarsus primus varus in patients under 15 years of age. The results were analysed after the patients were reviewed clinically and radiologically. Complications of the osteotomies and the factors that caused them are discussed. Poor results, irrespective of the type of osteotomy, were due to excessive shortening of the first metatarsal and/or dorsal tilting of the metatarsal head. In both instances there was persistent metatarsalgia.

Short- and long-term results for severe hallux valgus correction using a first metatarsal distal osteotomy

PurposeThe purpose of this study is to analyze the short- and long-term results of severe hallux valgus (HV) treated with a L-Reverse osteotomy.MethodsPatients treated with L-Reverse osteotomy for severe HV between the years 2006–2015 were included. Patients were evaluated preoperatively, at 3 months and 4 or more years postoperatively. Changes in the HV angle (HVA) and intermetatarsal angle (IMA) were measured. Clinical outcomes were assessed using the AOFAS score.Results28 patients were included. Pre-operative IMA changed from 18.1° (18–18.9°) to 7° (6.3–8.5°), and HVA from 38.5° (34.5–41.3°) to 10.0° (8.4–11.8°) at 3 month follow up (p < 0.005). Long term follow up was of 5.6 (4.9–6.4) years. IMA value was 7.5° (6.1°?8.1°) and HVA was 10.1° (6.7°?16.3°), with no statistical difference with initial correction (p = 0.14). Median AOFAS score was 92.7 (89–4–96.1).ConclusionL-Reverse osteotomy can achieve correction of HV severe deformities with good outcomes in long term follow up.Level of evidenceIII     

Clinical results of modified Mitchell's osteotomy for hallux valgus augmented with oblique lesser metatarsal osteotomy

PURPOSE: To evaluate postoperative results of modified Mitchell's osteotomy and its combination with oblique metatarsal osteotomy for the treatment of hallux valgus. METHODS: A total of 93 feet of 53 patients (2 men and 51 women) with hallux valgus underwent modified Mitchell's osteotomy and were followed up for at least 5 years. Patients' age ranged from 17 to 83 years, and the duration of follow-up ranged from 5 years one month to 18 years 4 months. Modified Mitchell's osteotomy was performed on 53 feet in 31 patients (group A), whereas modified Mitchell's osteotomy augmented with oblique lesser metatarsal osteotomy was performed to the remaining 40 feet in 22 patients (group B). Postoperative results were assessed using a clinical assessment system developed by the Tokyo Medical University based on 5 categories: pain in the first metatarsophalangeal, deformity of the metatarsophalangeal, plantar callosity and/or metatarsalgia of lesser metatarsals, the use of commercially available shoes, and local inflammatory symptoms. RESULTS: Mean total score improved from 3.8 to 7.9 on a 10-point scale. Scores for 2 categories--plantar callosity and/or metatarsalgia and the use commercially available shoes--were significantly higher in group B at postoperative 5 years. Before surgery, at postoperative 3 weeks, and at postoperative 5 years, respectively, the mean hallux valgus angles were 34.2, 12.0, and 17.1 degrees; mean M1-M2 angles were 16.7, 7.4, and 8.7 degrees; mean M1-M5 angles were 34.9, 25.8, and 26.6 degrees; and mean sesamoid bone shifts were 8.7 mm, 4.3 mm, and 5.9 mm. CONCLUSION: Modified Mitchell's osteotomy shortens the length of the first metatarsal bone and thus relieves tension in soft tissues such as the adductor hallucis. Nonetheless, the procedure can induce metatarsophalangeal joint malalignment and metatarsalgia, and plantar callosity may develop or persist after surgery. Combining oblique metatarsal osteotomy of the lesser metatarsal bones is useful in patients with uneven metatarsal bone lengths and metatarsophalangeal joint malalignment.
