ABSTRACT
Braquimetatarsia es el acortamiento anormal de uno o más metatarsianos. Tiene una incidencia de 0.02%-0.05% predominando en mujeres de 25 a 1. En un 72% puede ser bilateral. La etiología no es clara pero se plantea el cierre prematuro de la fisis dando un retardo en el crecimiento. La mayoría de las veces presenta síntomas causados por alteración en la mecánica de la parábola metatarsal como dolor e hiperqueratosis. Puede existir metatarsalgia y agregar en la evolución desviaciones digitales adicionales. El principal motivo de consulta es estético. El objetivo del reporte es mostrar dos técnicas quirúrgicas y los resultados clínicos correspondientes usando el score AOFAS, además de los resultados imágenológicos con hasta 5 años de seguimiento. Se describen dos pacientes y se analizan dos técnicas quirúrgicas diferentes para alargar los metatarsianos. Se trata de alargamientos agudos con interposición de injerto intercalar, en un caso mediante el procedimiento de Sandro Gianini con injerto de cresta ilíaca y en el otro con injerto de metatarsiano adyacente con modificación de la longitud del segundo y tercer metatarsiano restituyendo en ambos casos la parábola metatarsal. Obtuvimos buenos resultados al igual que series numerosas pudiendo recomendarse en casos similares.
Brachymetarsal is the abnormal shortening of one or more metatarsals. It has an incidence of 0.02%-0.05%, predominantly in women from 25 to 1. In 72% it can be bilateral. The etiology is not clear, but premature closure of the physis is suggested, giving growth retardation. Most of the time it presents symptoms caused by an alteration in the mechanics of the metatarsal parabola, such as pain and hyperkeratosis. There may be metatarsalgia and add additional digital deviations in the evolution. The main reason for consultation is aesthetic. The objective of the work is to show the surgical technique and the clinical results using the AOFAS score, in addition to the imaging results with up to 5 years of follow-up. Two patients are described and two different surgical techniques to lengthen the metatarsals are analyzed. These are acute lengthenings with intercalary graft interposition, in one case using the S.Gianini procedure with an iliac crest graft and in the other with an adjacent metatarsal graft with modification of the length of the second and third metatarsals, restoring in both cases the metatarsal parabola. We obtained good results. results as well as numerous series and can be recommended in similar cases.

Resumen: La braquimetatarsia (acortamiento metatarsal) afecta directamente el arco transverso del pie condicionando graves deformidades como hallux valgus, divergencia digital, dedo supraaducto, metatarsalgia, todas estas alteran la biomecánica del pie y la marcha. El tratamiento se realiza mediante dos técnicas principales, elongación en un solo tiempo quirúrgico con interposición de injerto óseo o elongación por callotaxis con minifijador externo. Existen variantes de ambas técnicas con la finalidad de disminuir las desventajas de cada una de ellas. El objetivo del tratamiento debe ser devolver la armonía estructural del antepié, con lo que mejora la biomecánica, traduciéndose en una evolución satisfactoria para los pacientes. En este artículo se presenta una técnica quirúrgica para pies con fisis cerradas que busca la reestructuración de la fórmula metatarsal y el restablecimiento de la estética y función. En el caso reportado se efectuó alargamiento en un solo tiempo del metatarsiano afectado con interposición de injerto óseo, acortamiento a los metatarsianos adyacentes, corrección del hallux valgus realizando las osteotomías necesarias y el tratamiento de las deformidades de los dedos menores con los métodos requeridos para cada caso. Esta técnica quirúrgica tiene como ventaja la corrección de todo el antepié en un solo tiempo quirúrgico sin necesidad de fijador externo ni de sus cuidados postoperatorios. Sus principales desventajas son la dependencia del injerto óseo estructural y la necesidad de vendaje funcional postquirúrgico hasta la consolidación ósea. En la paciente tratada se obtuvieron resultados clínicos y radiográficos satisfactorios.
Abstract: Brachymetatarsia (shortening of the metatarsal) directly affects the transversal arch of the foot causing severe deformities, such as hallux valgus, divergent toes, overlapping toes, metatarsalgia, all of these alter the biomechanics of the foot and gait. Treatment consists of two main techniques, one-stage lengthening with bone graft or elongation through callotaxis with external fixator; there are variants of both techniques used to minimize the disadvantages of each. The objective of treatment must be to return the structural harmony to the forefoot, improving the biomechanics, resulting in a satisfactory outcome for the patients. This article presents a surgical treatment for feet with closed physis to obtain the appropriate metatarsal formula and to reestablish aesthetics and function. This case was treated by means of one-stage lengthening with bone graft to the affected metatarsal; shortening of the adjacent metatarsals; hallux valgus alignment through the necessary osteotomies and the treatment of deformities of the lesser toes as needed. This surgical technique has as one of its advantages the correction of the entire forefoot at one time, without the need of an external fixator and its required postoperative care. Its main disadvantages are its dependence on structural bone graft and the need of postoperative dressing until healing of the bone has taken place. Satisfactory clinical and radiographical outcomes were obtained in treated patient.

La braquimetatarsia consiste en el acortamiento de 5 mm o más del arco parabólico metatarsal del pie, de uno o más de los metatarsianos; se relaciona directamente con el cierre prematuro del cartílago epifisario, o una prematura fusión de la línea epifisaria del extremo distal del metatarsiano, habitualmente el cuarto metatarsiano es el más afectado, predominio en el sexo femenino en relación de 25:1, afección bilateral 72%. Las causas pueden ser congénitas, post traumáticas o como parte de enfermedades específicas. Se realiza estudio prospectivo, comparativo de pacientes con diagnóstico de braquimetatarsia congénita, en el período comprendido de 2007-2008 y 2008-2012; el primer grupo consistió en siete pacientes de los cuales fueron seis niñas, un niño y en el segundo grupo: ocho pacientes, cinco niñas y tres niños. En el primer grupo se obtuvo un alargamiento de 21.1 mm en promedio, en el segundo grupo se obtuvo un alargamiento de 18 mm en promedio sin regresión, distrayendo 0.5 mm por día en ambos grupos. La elongación de los metatarsianos por callotaxis con minifijadores externos es un procedimiento satisfactorio para pacientes adolescentes próximos al cierre epifisario, teniendo mejores resultados con la distracción gradual a 0.5 mm por día.
Brachymetatarsia is the > 5 mm shortening of the metatarsal parabolic arc of the foot, in one or more metatarsals. It is directly related with the early closure of the epiphyseal cartilage or with early fusion of the epiphyseal line of the distal end of the metatarsal. The fourth metatarsal is usually the most affected one. Females are more commonly affected, with a female to male ratio of 25:1; 72% of cases have bilateral involvement. The causes may be congenital, posttraumatic or result from specific conditions. A prospective, comparative study was conducted of patients with a diagnosis of congenital brachymetatarsia seen in 2007-2008 and 2008-2012. Seven patients were included in the former period: six girls and one boy. Eight patients were included in the latter period: five girls and three boys. The mean shortening achieved in the first group was 21.1 mm; in the second one, 18 mm, without regression. The daily distraction in both groups was 0.5 mm. Metatarsal elongation by means of callotaxis with external fixators is an appropriate procedure for adolescent patients about to achieve epiphyseal closure. The best results are obtained with gradual distraction at a rate of 0.5 mm per day.

We present a rare case of bilateral idiopathic 4th metacarpal and metatarsal shortening. Patient was thoroughly investigated to rule out syndromic association. No intervention was done as the patient was asymptomatic.
ABSTRACT
Brachymetatarsia is a rare congenital deformity which occurs most commonly in the fourth metatarsal. Most common purpose of surgery is to make a normal metatarsal parabola for better external appearance as well as physiological load bearing under the metatarsal heads. Common surgical treatment for brachymetatarsia is lengthening of short metatarsal either by one-stage lengthening with intercalary bone graft or gradual lengthening by distraction osteogenesis. Sometimes shortening of long metatarsal is combined with lengthening of the short metatarsal. The function of the foot is diminished due to diverse complication accompanying lengthening of the metatarsal, therefore preoperative consultation about the functional result is essential.

Callotasis has been widely used to treat brachymetatarsia. But various complications have been reported. Avascular necrosis of the 4th brachymetatarsia treated by callotasis has not been frequently addressed in the literature. We report 1 cases of avascular necrosis of the 4th brachymetatarsia treated by callotasis with a review of the literature.

19 years old girl presented with bilateral 1, 4th brachymetatarsia. We have used an autograft interposition technique to lengthen the brachymetatarsia involving first and fourth metatarsal. The technique was to graft the bone fragment from the relatively long second and third metatarsal bone to be used as an autograft to the short first and fourth metatarsal bone. The method is superior in not having the necessity of a long term external fixator which is needed using callotasis method and in also avoiding the inconvenience of performing an allograft. Absence of donor site complication during autograft from iliac bone is also an advantage to be mentioned. Our technique can therefore be ascertained as a successful method in both cosmetic results and improvement of symptoms including reduction in length of recovery.

Among congenital brachymetatarsias fourth metatarsal bone shortening is most common form and unusually involves multiple metatarsal bones. We report a case of the patient with bilateral 1st and 4th multiple rays brachymetatarsia treated with callostasis. Twenty eight months after procedure, right side showed 1st metatarsal lengthening about 11.5 mm (29.23%) and 4th metatarsal 17.86 mm (35.87%). Twenty one months later, left side showed 1st metatarsal lengthening about 14.58 mm (36.8%) and 4th metatarsal 20.52 mm (43.01%). In healing index right side showed 1st metatarsal 3.4 month/cm, 4th metatarsal 2.5 month/cm and left side showed 1st metatarsal 4.2 month/cm, 4th metatarsal 2.3 month/cm. Final follow-up results presented excellent outcome in cosmetic problem, easy wear of shoes, and measurement of patient's self satisfaction.

In general, the operative treatment of the brachymetatarsia is the lengthening of the affected metatarsal bone due to the cosmetic problem rather than the functional one. We experienced 22 year-old female bilateral congenital foot deformities such as hallux varus and 1,4th brachymetatarsia treated with reverse Scarf osteotomy on the hallux varus and massive axial metatarsal shortening Weil osteotomy on the 2,3,5th metatarsals which could reconstruct the normal metatarsal parabola.

PURPOSE: To evaluate the clinical results of lengthening in first brachymetatarsia using a distraction osteogensis with an external fixator. MATERIALS AND METHODS: Fifteen cases in nine patients, who had received firstmetatarsal distraction osteogenesis from January 1996 to December 2002, were enrolled in this study. At the final follow-up, the application time of the external fixator was measured and the percentage of lengthening, healing index, complication rate, and the patients satisfaction was analyzed. The patients satisfaction was evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) scores, which were scored according to the level of stiffness, pain, function, and alignment. RESULTS: The score according to the AOFAS-Hallux Metatarsophalangeal joint and Inter-Phalangeal joint scale was excellent in 13 patients and good in 2. All patients were satisfied with the procedure. The average percentage of lengthening was 48.7%. The average healing index was 72.8 days/cm. The major complication was a cavus foot, which was noticed in four feet. All the first toes showed some decrease in motion at the metatarsophalangeal joint. The other complications were hallux valgus, angulation of the metatarsals, and a pin tract infection each in two feet. CONCLUSION: Distraction osteogenesis is an effective method for first brachymetatarsia. However, excessive lengthening can cause potential complications.

PURPOSE: To present our treatment protocol and surgical outcome for patients with congenital brachymetatarsia in which treatment was decided according to the number of affected rays. MATERIALS AND METHODS: Sixty-nine metatarsals in 44 patients with single or multiple congenital brachymetatarsia were included in the study. When a single ray was affected in a foot, we performed a one-stage lengthening using an intercalary autogenous iliac bone graft. We overcame excessively short rays by the double level lengthening at the metatarsal and proximal phalanx as one stage. When multiple rays were affected in one foot, we performed a one-stage combined shortening and lengthening procedure without an iliac bone graft. RESULTS: All patients were satisfied with the cosmetic and functional results. The average length gain by one-stage lengthening in 56 metatarsals of 38 patients was 14 (6-21) mm. Six patients with a combined shortening and lengthening procedure regained a nearly normal parabola of the involved foot. Neurovascular complication was not identified. CONCLUSION: Satisfactory results were achieved for the treatment of patients with congenital brachymetatarsia, by individualizing the surgical options according to the number of affected rays and general foot appearance.

PURPOSE: To analyze the outcome of metatarsal lengthening of first brachymetatarsia by callotasis using an external fixator. MATERIALS AND METHODS: Between January 1998 and February 2004, 10 patients (17 cases) were reviewed. The mean age at operation was 17.3 years. Seven patients had bilateral first brachymetatarsia and eight patients had combined 4th brachymetatarsia. The operations were performed with a monoexternal fixator, and distraction was started at a rate of 0.75 mm/day after 7 days. The radiographic results were evaluated by lengthening amount and percentage, fixation time, and healing index. Complications and AOFAS score were evaluated. RESULTS: The average lengthening amount was 17.7 mm and the average lengthening percentage was 43.4%. The external fixation time was 107 days and average healing index was 69.8 days/cm. The evaluation according to AOFAS score was excellent in 12 cases and good in 5 cases. Complications were 4 cases of hallux valgus, 4 of metatarsophalangeal joint stiffness, 3 of medial angular deformity, 3 of pes cavus, 2 of pin breakage, 2 of pin site infection, and 1 of skin hyperpigmentation. CONCLUSION: Callotasis for 1st brachymetatarsia is a very useful treatment method with high patient satisfaction, excellent healing rate and early ambulation without bone graft. Nevertheless, great care must be taken to minimize the various possible complications.

PURPOSE: To report on a new operative technique of distraction osteogenesis and it's results in brachymetatarsia. MATERIALS AND METHODS: 17 patients (39 metatarsal bones) formed the basis of this study (male: female-2: 15). To prevent varus deformity of the hindfoot after lengthening, all screws were inserted at the same level from the medial aspect of the first metatarsal bone for horizontal distraction in the anterior direction, rather than distraction in the direction of the anatomical axis. Also, care was taken to ensure that the screw for the fourth metatarsal bone did not interpose with the fifth extensor tendon. RESULTS: All cases achieved satisfactory lengthening and bony union, except 1 case. The healing index increased with patient's age. Plantar capsular release was performed in seven cases, six of which had been previously operated on bilaterally. There was no hindfoot varus deformity or entrapment of the fifth extensor tendon on final follow up. CONCLUSION: Varus deformity of the hindfoot can be prevented by horizontal distraction of the first metatarsal bone. Also, entrapment of the fifth extensor tendon can be prevented by careful handling of the fifth extensor tendon during operation on the 4th metatarsal bone. Complications of stiffness or of an increase in treatment period were mainly found in bilaterally operated or relatively old (over 20 year-old) patients.

PURPOSE: We retrospectively reviewed outcomes, complications and their influencing factors after distraction osteogenesis for fourth brachymetatarsia. MATERIALS AND METHODS: We performed twenty-two cases of metatarsal lengthening with external fixator in sixteen patients for fourth brachymetatarsia from May 1998 to May 2000. At the final follow-up, AOFAS scores were awarded according to stiffness, pain, function, alignment and the satisfaction of patients. RESULTS: On average, the gain in length was 16.5 mm, the percentage of lengthening 38.9%, and the healing index 72.9 days/cm. There were some complications including subluxation of the metatarsophalangeal joint in 7 cases, stiffness in 5 cases, pin tract infection in 2 cases, and angular deformity in 3 cases. Those having a percentage of lengthening of less than 40% and those involving only the metatarsus had better results. Most patients were satisfied with the corrected result, though one unsatisfied patient underwent revision surgery. CONCLUSION: Even though distraction osteogenesis for fourth brachymetatarsia is effective, excessive lengthening in patients involving both metatarsus and phalange can produce minor complications.

PURPOSE: To evaluate the importance of various surgical techniques in the treatment of brachymetatarsia. MATERIALS AND METHODS: The study involved 33 cases, categorized as follows: group A: treated by one-stage lengthening (4) or callotasis (9) without bone shortening; group B: treated either by one-stage lengthening (3) or callotasis (15) with bone shortening or bone shortening only (2). Fifteen patients were reviewed in terms of the length gain (LG), healing index (HI), percentage increase (PI), and complications. RESULTS: The results in both group A [one-stage lengthening (mean: LG 1.4 cm, HI 1.2 months/cm, PI 0.3) and callotasis distraction (LG 1.8 cm, HI 2.2 months/cm, PI 0.4)] and group B [one-stage lengthening (LG 1.3 cm, HI 1.3 months/cm, PI 0.3) and callotasis (LG 1.8 cm, HI 2.1 months/cm, PI 0.5)] were satisfactory. The averaged amount of bone shortening at 23 levels was 0.8 cm. It magnified the cosmetic effect and consequently reduced on average 1.8 months after treatment period in the callotasis group. CONCLUSION: In managing brachymetatarsia, bone shortening of the neighboring metatarsal and phalanx, a form of epiphysiodesis, and surrounding soft tissue release reduce the treatment period and the associated complications.

We performed 34 metatarsal distraction lengthenings in 17 patients for the treatment of brachymetatarsia from May 1994 to December 2001. The average amount of lengthening was 15.6 mm(35.9%), range: 10.1 - 22.9 mm(18.8 - 64.1%). The average healing index was 75 days/cm(range, 49 - 119 days/cm). Complications included five cases of pin site infection, 3 cases of under-correction and 1 case of plantar angulation. All the pin site infections were well responded to oral antibiotics, but reduced the lengthening speed. In two cases, the early removal of fixator resulted in under-correction. The early removal was occurred by either patient's impatience to wear fixator or physician's hasty. In one case, it was not possible to distract because of the osteoporotic change of osteotomized segment during distraction. Plantar angulation of first metatarsal resisted to bone remodeling was corrected by wedge osteotomy. The expected joint stiffness was not paid any attention in all cases. Non-union, fracture and any neuovascular complications were not observed. We have found that the metatarsal lengthening by callotasis under the close physician's supervision of those problems, especially plantar angulation of first metatarsal, is safe and reliable procedure.

The purpose of this study was to analyze the fate of intercalated bone graft and the satisfaction of patients with brachymetatarsia of the 4th toe on the clinical results after one-stage lengthening with autogenous iliac bone graft. In last 6 years, 30 feet in 17 patients with brachymetatarsia were corrected with one-stage operation that was composed of Z-plasty of skin, extensor tendon and intercalated iliac bone graft, which appeared as ball-and- socket figure at the metatarsophalangeal joint. The length of harvested iliac bone graft was 18 mm in average(14 -23 mm) and there was bone resorption about 1.1 mm(0.1- 3.0), (7.1%) postoperatively. Postoperative digital fluoroscopy showed 83%(25/30) new joint(pseudojoint) formation of intercalated iliac bone grafts between proximal phalangeal bone and metatarsal bone. The objective functional evaluation with AOFAS scale was 89.4 in average(80 - 100) and subjective satisfaction on the aesthetic aspect was also high. There was no neurovascular impairment nor recurrence of brachymetatarsia even after one-stage lengthening with intercalated iliac bone graft.
