Abstract
BACKGROUND Symptomatic patients with severe brachymetatarsia are commonly treated with callus distraction using external mini-fixator (EF) or internal device (ID). This study points out advantages and limitations of both methods comparing clinical and radiographical parameters. METHODS Retrospective analysis of 21 metatarsal bones in twelve patients. Twelve metatarsals were treated with ID (Genos Mini), nine with EF (MiniRail). RESULTS Mean lengthening distance was 17.3 mm using EF and 11.7 mm using ID (p = 0.016). Adverse results were observed in 89% of metatarsals treated with EF and in 33% treated with ID (p = 0.011). Postoperative surgical intervention was required in 33% using EF compared to 0% using ID (p = 0.031). Mean total German Foot Function Index (FFI-T) improved from 49 to 33 using EF and from 47 to 22 using ID (p < 0.001). CONCLUSION CD is a reliable surgical treatment for BMT. Surgeons should be aware of implant-related advantages and complications when counseling patients about treatment options.

Abstract
Brachymetatarsia is a malformation characterized by an abnormal reduction in the length of 1 or more metatarsal bones. It occurs because of early closure of the growth plate of the affected metatarsal. Generally, it is caused by a congenital disorder and it usually occurs bilaterally. With a greater prevalence in females, it most often affects the fourth metatarsal, followed by the first metatarsal. Surgical treatments proposed include using external mini-fixators or bone grafts in a single step to lengthen the metatarsal. In this review, 62 scientific articles about brachymetatarsia were analyzed with key demographic and epidemiological aspects of this pathology. The prevalence of bilateral brachymetatarsia was 47%, and the female to male ratio was 10.53:1. Both these findings appear to contradict the usual data reported for brachymetatarsia. A better understanding of this disorder will enable an appropriate therapeutic approach according to the psychological and social profile of affected individuals.

Abstract
BACKGROUND Brachymetatarsia is a rare congenital or developmental condition that results in a short metatarsal. The condition most commonly affects the fourth metatarsal of young and adolescent females. It does not usually produce a functional problem. However, it may produce a significant cosmetic problem especially in young women. The authors present their experience in gradual distraction of the fourth metatarsal to tackle this problem in adults. METHODS That was done using a monolateral frame in 11 feet of female patients with an average age of 23 years. Evaluation depended upon the achievement of the target length, angulation, pain, and satisfaction of the patient. RESULTS There were eight excellent and three good results after an average follow up of 2.6 years. Aside from nine cases of mild pin-tract infection, complications were few and minor. CONCLUSIONS We recommend distraction osteogenesis as the treatment of choice for brachymetatarsia of the fourth toe.

Abstract
A 33 years old female patient presented with posttraumatic pain in the right foot for which radiographs of the right foot was advised. No fracture was detected on radiographs and patient was managed conservatively on medications and posterior splint immobilization. We found coincidentally a short fourth metatarsal and an accessory navicular bone in the right foot radiographs. After 3 weeks of immobilization, she underwent mobilization of the right foot, weight bearing and intensive physio- therapy for 6 weeks. After two months of injury she was still complaining of pain on the plantar aspect of right foot which was diagnosed as metatarsalgia and operated on by excision of the neuroma present in the 3rd web space of the right foot. After surgery she was completely relieved of pain and could do activities well related to the right foot.

Abstract
Brachymetatarsia deformity is a cosmetically displeasing anomaly that can become physically symptomatic. The surgical techniques most commonly used to repair the anomaly include single-stage lengthening with a bone graft, callus distraction, or a combination of bone grafting and callus distraction. A systematic review of the published data was performed to compare the outcomes of these 3 surgical procedures. A total of 61 studies reporting the use of callus distraction or single-stage lengthening, or both, for the treatment of brachymetatarsia were included in the present review. The incidence of major postoperative complications after callus distraction, single-stage lengthening, and the combination procedure was 49 (12.62%), 13 (3.72%), and 3 (33.33%), respectively. The number of minor complications with callus distraction, single-stage lengthening, and the combination procedure was 152 (39.18%), 55 (15.76%), and 1 (11.11%); the mean percentage of the original length achieved was 37.36%, 25.98% and 36.00%; and the mean length achieved was 17.5, 13.2, and 14.0 mm, respectively. The healing index (mo/cm) and healing time was 2.31 and 16.04 weeks, 1.90 and 9.35 weeks, and 3.93 and 14.62 weeks for callus distraction, single-stage lengthening, and the combination procedure, respectively. Our findings indicate that the callus distraction technique is associated with greater length gained but results in greater complication rates and requires almost twice the time to heal. Single-stage lengthening with a bone graft was associated with fewer complications and faster healing times than callus distraction but with lesser gains in length. From the information reported in the studies we reviewed, the prevalence of bilateral brachymetatarsia was 44.52%, and the female/male ratio was 13.7:1. Both of these findings seem to contradict the usual data given (72% for bilateral brachymetatarsia and a female/male ratio of 25:1).

Abstract
Brachymetatarsia is a congenital or developmental condition that results in a short metatarsal. Problems that arise from this condition can include pain, difficulty with shoe wear, and cosmetic concerns. Multiple techniques have been described that successfully correct the deformity, including both acute and gradual distraction. We describe a modification of the technique of gradual lengthening by way of distraction osteogenesis in which an axial transarticular K-wire is incorporated into a monolateral frame, thereby increasing the stability of the construct and potentially minimizing complications.

Abstract
BACKGROUND Congenital brachymetatarsia, a shortened metatarsal bone, can be corrected surgically by callus distraction or one-stage lengthening using bone graft. QUESTIONS/PURPOSES We asked whether one-stage metatarsal lengthening using metatarsal homologous bone graft could improve forefoot function, lead to metatarsal healing, restore metatarsal parabola, and improve cosmetic appearance. PATIENTS AND METHODS We retrospectively reviewed 29 patients (41 feet) in whom we lengthened 50 metatarsals. Surgery consisted of a transverse proximal osteotomy of the metatarsal shaft and interposition of a metatarsal homologous bone graft (average, 13 mm long) fixed with an intramedullary Kirschner wire. Minimum followup was 3 years (mean, 5 years; range, 3-11 years). RESULTS Bone union was achieved in all cases. The mean preoperative American Orthopaedic Foot and Ankle Society score was 37 points (range, 28-53 points) and the mean postoperative score was 88 points (range, 74-96 points), with an average improvement of 51 points. Radiographically, the mean gain in length was 13 mm (range, 10-15 mm), and the mean percentage increase was 23%. CONCLUSIONS One-stage metatarsal lengthening using interposition of metatarsal homologous bone graft to correct congenital brachymetatarsia has low morbidity for the patient, limited complications, short recovery times, and restores forefoot anatomy. LEVEL OF EVIDENCE Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND Congenital brachymetatarsia is often treated with callus distraction. This technique is associated with a variety of complications. We investigated complications encountered in treatment of brachymetatarsia in four female patients and reviewed adjunctive procedures performed to treat these complications. METHODS We reviewed five distraction osteogenesis procedures performed in four female patients with congenital shortening of the fourth metatarsal over a 3-year period. Serial radiographs were obtained weekly until bone consolidation was achieved, at which time the external fixator was removed. Follow-up ranged from 5 to 10 months. RESULTS Three patients (four metatarsals) were satisfied with the cosmetic and functional outcomes of their procedure. One patient was dissatisfied with the cosmetic result owing to a short digit from a short proximal phalanx but was completely functional and resumed all of her normal activities. Complications associated with callus distraction were decreased range of motion and stiffness at the metatarsophalangeal joint, flexion deformity of the digit, angulation of the metatarsal, prolonged distraction time due to pain, fracture of the bone callus, pin-site infection, and an undesirable cosmetic appearance due to a short proximal phalanx. Adjunctive procedures were needed in some of these cases and yielded good results. CONCLUSIONS Callus distraction is an effective treatment for congenital shortening of the fourth metatarsal, but the procedure is associated with a number of complications. Because most patients proceed with surgery for cosmetic reasons, it is important to present the possible complications and the adjunctive surgical procedures that may be necessary for a desirable outcome.

Abstract
Brachymetatarsia is a rare clinical entity that presents a complicated case to the treating surgeon. One-stage lengthening procedures with a variety of biologic and synthetic implants are preferred for metatarsals that only need to be lengthened up to 15 mm, whereas gradual lengthening allows for greater length gain and concomitant lengthening of the soft tissues. Adjacent metatarsal shortening may be used in conjunction with lengthening procedures to restore the parabolic arc of the metatarsal heads. Management should be tailored to the patient's individual deformity and expectations. Individualization of surgical techniques and patient selection criteria can result in a cosmetic, functional result that is satisfactory to the clinician and the patient.

Abstract
BACKGROUND This study investigated metatarsal lengthening by distraction osteogenesis for fourth brachymetatarsia in 22 metatarsals (16 patients). METHODS From May 1997 to May 2000, lengthening was performed with a monoexternal fixator, and distraction was started at a rate of 0.5 mm per day after a latency period of approximately 7-10 days. RESULTS The average gain in length was 16.5 mm (range, 13-21 mm), equivalent to an increase of 39% (range, 28-51%), and the average healing index was 72.9 days/cm (range, 51.7-95.7 days/cm). The American Orthopaedic Foot and Ankle Society (AOFAS) average score for lesser toe was 86.3 (range, 47-100). The most common residual complication was subluxation of metatarsophalangeal (MTP) joint in five cases, with partial or total stiffness of the MTP joint. These complications happened in the group of metatarsals excessively lengthened more than 40% and made the AOFAS score poorer. The other complications were three cases of angular deformity in the lengthened bone, and two cases of pin-tract infection. CONCLUSION Although distraction osteogenesis is an effective method to address fourth brachymetatarsia, stiffness or subluxation of the MTP joint was not uncommon. To avoid complications that can happen as a result of excessive lengthening, careful preoperative radiographic measurement to calculate the optimal amount of lengthening may help us to avoid overlengthening and the complications that accompany it.

Abstract
The use of external fixation in foot and ankle surgery has steadily increased with the advent of devices geared toward the foot and ankle that have evolved over the past decade, as well as a greater understanding of the indications and advantages of external fixation. The application of external fixators in the forefoot may at first glance seem both limited and possibly overkill, but once the basics of external fixation and the types of devices available are understood the options for use become numerous.

Abstract
Brachymetatarsia is an uncommon condition, and when present, it is usually asymptomatic. A case report demonstrating the use of distraction lengthening for symptomatic multiple congenital short metatarsals is presented. A 15-year-old female with congenital short third and fourth metatarsals was treated for painful transfer lesions under the second and fifth metatarsal heads and a secondary hallux valgus deformity. Surgical correction with a chevron osteotomy, soft tissue reconstruction of the second toe, and distraction lengthening of the third and fourth metatarsals was performed. Three years after treatment, the patient has an excellent clinical correction, with no evidence of recurrent transfer lesions. To our knowledge, this is the first report demonstrating the use of distraction lengthening without supplemental bone graft for multiple short metatarsals in a single extremity.

Abstract
Chronic metatarsalgia is a condition found through the years to present many treatment difficulties. These difficulties began with a lack of understanding, not only concerning the etiologic nature of this condition, but failure to appreciate the surgical treatment ramifications inherent to alterations in the metatarsal parabola. These failures have subsequently led to lesions under the adjacent metatarsal heads, stress fractures, flail toes, and other postoperative pathology. This often leads to further surgical intervention or accommodative modifications. The authors offer an analysis of surgical approaches to this problem and present a more predictable surgical technique to enhance the metatarsal parabola, while decreasing either excessive plantarflexion of a particular metatarsal or set of metatarsals. To date the senior author (E.L.) has performed the asymmetric "V" osteotomy on 30 patients for a total of 40 metatarsals. After a 12- to 18-month postoperative period, there have been no significant complications, including recurrences, transfer lesions, excessive secondary bone callous, malunions, or adjacent metatarsalgia. Delayed union with secondary bone callous has developed in two instances. The authors introduce an innovative surgical approach to structural metatarsal abnormalities as a distinct advantage to other previously described osteotomies with greater predictability, better anatomic reduction, primary bone healing, and faster return to normal activities.

Abstract
Though by no means a new concept, the science of callus distraction has stimulated significant interest among surgeons over the past several years. As our knowledge and understanding of the principles of this technique have evolved, the clinical indications have been expanded. In this manuscript, we will illustrate several examples of these broadened indications. An innovative alternative to the Evans opening wedge calcaneal osteotomy, which usually requires bone graft or bone graft substitutes, is presented.
