Abstract:
Metatarsalgia is a recognised complication following iatrogenic shortening of the first metatarsal in the management of hallux valgus. The traditional surgical treatment is by shortening osteotomies of the lesser metatarsals. We describe the results of lengthening of iatrogenic first brachymetatarsia in 16 females. A Scarf-type osteotomy was used in the first four cases and a step-cut of equal thicknesses along the axis of the first metatarsal was performed in the others. The mean follow-up was 21 months (19 to 26). Relief of metatarsalgia was obtained in the six patients in whom 10 mm of lengthening had been achieved, compared to only 50% relief in those where less than 8 mm of lengthening had been gained. One-stage step-cut lengthening osteotomy of the first metatarsal may be preferable to shortening osteotomies of the lesser metatarsals in the treatment of metatarsalgia following surgical shortening of the first metatarsal.Keywords:

The treatment of metatarsalgia secondary to the plantar prominence of the metatarsal heads has lead to the development of numerous orthotic devices designed to decrease pressures in these areas. In spite of the considerable cost of some of these devices, there has yet to be much objective evidence of their efficacy. This study assessed the effect of a simple metatarsal pad on pressures transmitted to the metatarsal heads. Quantitative measurements of dynamic peak pressures for 10 asymptomatic subjects with and without metatarsal pads were made using the pedobarograph. Female volunteers had a reduction in peak metatarsal pressures from 12% to 60% when a small metatarsal pad was appropriately applied to the foot. In two of five males there was a decrease in metatarsal pressure of 14% to 44%. One male had no change in pressure, while two others had an increase in pressure from 8% to 28%. When properly positioned and appropriately monitored, metatarsal pads can be an inexpensive and effective means of reducing metatarsal pressures.

The first metatarsal bone can shorten after a distal chevron metatarsal osteotomy (DCMO). This shortening can result in a postoperative second metatarsal transfer lesion. The aim of the present study was to investigate the occurrence of second metatarsal transfer lesions after DCMO.This study involved 185 feet (138 patients), with hallux valgus (HV) deformity, treated with DCMO with Akin osteotomy. The mean patient age was 51.7 years (range, 21 to 74). Patients were followed for an average of 28 months, between June 2004 and June 2010. We measured the length of first metatarsal relative to second metatarsal preoperatively and postoperatively, using Morton's and Hardy-Clapham's methods. A second metatarsal transfer lesion was defined as a newly developed lesion, including metatarsalgia, a painful callosity, or a painless callosity, which was not present prior to the DCMO. The relation of the shortened first metatarsal after DCMO with the occurrence of second metatarsal transfer lesion was evaluated.Second metatarsal transfer lesions (painless callosity) developed in 5 feet (2.7%) of 185 feet. Twenty-four preoperative second metatarsal lesions were improved postoperatively. The median shortening of the first metatarsal bone after DCMO was 0.6 mm according to Morton's method (range, -6.4 to 6.4), and 1.9 according to Hardy-Clapham's method (range, -5.8 to 5.8). According to the extent of first metatarsal shortening after DCMO by Hardy-Clapham's method and Morton's method, there was no significant difference of the occurrence of second transfer metatarsal lesions (P = .259 and P = .176, respectively).In our study, second metatarsal transfer lesions developed in 2.7% of feet after DCMO. The occurrence of second metatarsal transfer lesions did not appear to be correlated with the degree of first metatarsal shortening in cases with less than 5.8 mm shortening.Level IV, retrospective case series.

Introduction: One of the complications of first metatatarsal osteotomies is metatarsalgia secondary to shortening of the first metatarsal. Conservative treatment with insoles is not acceptable to all patients and the traditional treatment of this condition is by shortening osteotomies of the lesser metatarsals (eg Weil, Helal)- the latter osteotomies themselves have complications of causing pain or stiffness in the lesser toes. Purpose: The aim of this work is to report our results of step cut metatarsal lengthening of iatrogenic first brachymetatarsia. Patients and Methods: 16 female patients had metatarsal lengthening of iatrogenic first brachymetatarsia. A typical Scarf type osteotomy was used in the first 4 cases and a simple step cut of equal thicknesses along the axis of the first metatarsal was performed in the next 12 procedures. Results : When 10mm lengthening was done, the metatarsalgia was relieved in all of the 6 patients, in contrary to only 50% relief of symptoms in the patients when less then 8mm lengthening was achieved. Conclusions: One stage step cut lengthening osteotomy of the iatrogenic short first metatarsal, when over 8mm length is achieved, is safe with good results and is a preferable alternative to shortening osteotomies of the lesser metarsals in the treatment of metarsalgia due to inappropriate shortening of the first metatarsal.

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.

Abstract Background: Metatarsalgia is a common foot condition. The metatarsophalangeal stabilizing taping technique described by Yu et al. has shown good clinical results as a provisional treatment in propulsive metatarsalgia. 35 The Fixtoe Device®, a novel orthopedic device, intends to simulate stabilizing tape. However, to date, there is no evidence of its effectiveness. Methods: The aim of this study was to a ssess plantar pressure changes using the Fixtoe Device®, in comparison with the traditional method (stabilizing tape) in a young, healthy sample thorough a cross-sectional study. Maximal pressure (Kpa) and pressure-time integral (Kpa/s) in the second metatarsal head were measured in twenty-four healthy volunteers. Registers were taken in four different conditions: barefoot, traditional stabilizing tape, Fixtoe Device® without metatarsal pad, and Fixtoe Device® with metatarsal pad. Results: Mean second metatarsal head maximal pressure and mean pressure-time integral showed statistical difference among the four analyzed conditions (p < 0.0001 in both cases). The improvement in maximal pressure and pressure-time integral obtained in each intervention also showed significance (p < 0.0001 in both cases). Comparing the improvement of the Fixtoe Device® with and without metatarsal pad with that of tape condition showed a moderate to high and moderate effect size for both peak pressure and pressure-time integral reduction. Conclusions: The Fixtoe Device® reduces median maximal pressure and median pressure-time integral under the second metatarsal head in healthy young individuals. The Fixtoe Device® shows higher effectiveness than the traditional second metatarsophalangeal joint stabilizing taping technique. To our knowledge, this is the first investigation proving the effectiveness of the recently developed Fixtoe Device® in terms of plantar pressure modification, which leads the way to its use in clinics.

Symptom relief of recalcitrant metatarsalgia can be achieved through surgical shortening of the affected metatarsal, thus decreasing plantar pressure. Theoretically an oblique metatarsal osteotomy can be oriented distal to proximal (DP) or proximal to distal (PD). We characterized the relationship between the amount of second metatarsal shortening, osteotomy plane, and plantar pressure. We hypothesized that the PD osteotomy is more effective in reducing metatarsal peak pressure and pressure time integral. We performed eight DP and eight PD second metatarsal osteotomies on eight pairs of cadaveric feet. A custom designed robotic gait simulator (RGS) generated dynamic in vitro simulations of gait. Second metatarsals were incrementally shortened, with three trials for each length. We calculated regression lines for peak pressure and pressure time integral vs. metatarsal shortening. Shortening the second metatarsal using either osteotomy significantly affected the metatarsal peak pressure and pressure time integral (first and third metatarsal increased, p < 0.01 and <0.05; second metatarsal decreased, p < 0.01). Changes in peak pressure (p = 0.0019) and pressure time integral (p = 0.0046) were more sensitive to second metatarsal shortening with the PD osteotomy than the DP osteotomy. The PD osteotomy plane reduces plantar pressure more effectively than the DP osteotomy plane.
