RESUMO
PURPOSE: Based on the tripod concept of load distribution, our study aimed to evaluate whether a slight extension of first metatarsal (M1) that may occur after the Lapidus procedure (LP) could alter the radiographic measurements of the hindfoot and influence clinical and functional outcomes. METHODS: Twenty-five patients (27 feet) were reviewed. Hindfoot radiographic analysis was based on seven measurements. Clinical and functional outcomes were evaluated with self-reported questionnaires. Transfer metatarsalgia was also assessed. Correlation analysis was performed according to variations of the studied variables. RESULTS: The average extension of the M1 was 4.26 degrees (p < 0.001). None of the hindfoot radiographic measurements changed significantly (p = 0.13, p = 0.50, p = 0.19, p = 0.70, p = 0.11, p = 0.36, p = 0.83). Patients improved on most questionnaires (p < 0.001). None presented transfer metatarsalgia. No correlation between M1 extension and clinical and functional outcomes was found. CONCLUSION: Possibly there is a tolerance of M1 extension in which it does not alter the radiographic measurements of the hindfoot, overload the lesser metatarsals, or compromise clinical and functional outcomes.

Metatarsalgia is a common problem that refers to the tenderness and pain beneath the forefoot. Many metatarsal shortening osteotomies have been described to alleviate metatarsal overload; however, these osteotomies have been associated with a high complication rate of floating toe deformity. We present a case study that describes an innovative technique for the treatment of lesser metatarsalgia that allows for the repositioning of the metatarsal head, using a stable screw fixation designed to minimize the common complication of the floating toe.

OBJECTIVE: To analyze the clinical results of metatarsalgia treated with percutaneous distal metatarsal metaphyseal osteotomies (DMMO). MATERIAL AND METHODS: Prospective and continuous study of 29 patients with isolated unilateral mechanical metatarsalgia, operated on with DMMO, with a mean follow-up of 38 months. The mean age of the patients was 58 (range: 50-67) years and only two men. We use the AOFAS score, we obtained the digital and metatarsal formulas on the X-rays. We record the subjective assessment of the surgeon and the patient at the end of the treatment. RESULTS: The improvement in the final score exceeded 80 points in all cases (p = 0.000), with a significant improvement in pain (p = 0.000) and calluses (p = 0.000), improving metatarsal-phalangeal joint stability and interphalangeal and metatarsal alignment. The type of footwear did not change after surgery, we found no variation in mobility, neither in the metatarsophalangeal joints (p = 0.382), nor in the interphalangeal joints (p = 0.672). After surgery increased the square foot morphology (p = 0.027) but the metatarsal formula underwent few modifications. Patients and surgeons were in 96% of the cases "very satisfied" or "satisfied". CONCLUSION: DMMO achieves a high degree of satisfaction in patients and in the surgeon, pain and hyperkeratosis under the head of the painful metatarsals disappear and that significantly improves the functional capacity of patients.
OBJETIVO: Analizar los resultados clínicos de las metatarsalgias tratadas con osteotomías metafisarias metatarsales distales (DMMO) por vía percutánea. MATERIAL Y MÉTODOS: Estudio prospectivo y continuo de 29 pacientes afectados de metatarsalgia mecánica aislada unilateral, intervenidas con una DMMO, con un seguimiento medio de 38 meses. La edad media de los pacientes fue 58 (rango: 50-67) años y sólo dos hombres. Utilizamos la escala AOFAS, anotamos la fórmula digital y metatarsiana sobre la radiografía. Registramos la valoración subjetiva del cirujano y del paciente al final del tratamiento. RESULTADOS: La mejoría de la puntuación final superó los 80 puntos en todos los metatarsianos (p = 0.000), con una mejoría significativa del dolor (p = 0.000) y de las callosidades (p = 0.000), mejorando la estabilidad articular metatarso-falángica e interfalángica y la alineación de los metatarsianos. El tipo del calzado no cambió después de la cirugía, no encontramos variación de la movilidad, ni en las articulaciones metatarso-falángicas (p = 0.382), ni en las interfalángicas (p = 0.672). Después de la cirugía aumentaron los pies cuadrados (p = 0.027). La fórmula metatarsiana sufrió pocas modificaciones, 96% de los pacientes y de los cirujanos se mostraron "muy satisfechos" o "satisfechos". CONCLUSIÓN: La DMMO consigue un alto grado de satisfacción en pacientes y también en el cirujano, elimina el dolor y la hiperqueratosis bajo la cabeza de los metatarsianos dolorosos que mejora significativamente la capacidad funcional de los pacientes.

INTRODUCTION: Metatarsalgia is the most common reason for consultation in orthopedic pathology of the foot. The key to its treatment lies in the correct determination of the symptoms, which are biological, morphological and mechanical alterations responsible for pain. Weil´s osteotomy is commonly used for multiple forefoot pathologies, including metatarsalgias. MATERIAL AND METHODS: We included patients with first-line failure syndrome and associated mechanical metatarsalgia-producing deformities. The minimum follow-up was six months. All individuals were interviewed with a standardized questionnaire based on the AOFAS, a survey to know their degree of satisfaction about the surgery. RESULTS: Twelve female subjects with a mean age of 51 years were recruited between March and September of 2013. Seven right feet, five left. The AOFAS values improved only in six, in which an excellent result was obtained; five rated them as good and six as unsatisfactory. CONCLUSIONS: In a very small series, postoperative complications were observed when the shortening of the metatarsal was greater than four millimeters, with the appearance of stiffness (floating finger).

OBJECTIVE: The objective of our study was to assess the diagnostic performance and associations of the direct and indirect MRI features of the metatarsophalangeal (MTP) joint that are thought to be related to tears of the plantar plate (PP) using surgical findings as the reference standard. MATERIALS AND METHODS: We retrospectively included 23 patients with symptomatic instability of lesser MTP joints who had undergone preoperative 1.5-T MRI and surgical assessment. The MRI examinations were independently assessed by two musculoskeletal radiologists. Using the surgical data as the reference standard, we calculated the sensitivity, specificity, and accuracy of each MRI feature in the detection of PP tears. Multivariate logistic regression analysis was performed to identify which MRI features were independently associated with PP tears. Interobserver reliability was assessed using kappa statistics. RESULTS: Forty-five lesser MTP joints were included. The presence of pericapsular fibrosis was highly sensitive (91.2%), specific (90.9%), and accurate (91.1%) for the diagnosis of PP tears. With a cutoff value of 0.275 cm, the PP-proximal phalanx distance had a sensitivity of 64.7%, specificity of 90.9%, and accuracy of 71.1% in diagnosing PP tears. CONCLUSION: In patients with clinical features indicating lesser MTP joint instability, some direct and indirect MRI features exhibited good to excellent diagnostic performance in detecting the presence of PP tears.

Introduction: mechanical metatarsalgias difficult to orthopedic treatment require surgical treatment. We report our experience with percutaneous surgery. Objectivs: show the effectiveness of percutaneous distal osteotomy in the treatment of mechanical metatarsalgias. Methods: a retrospective study of 100 patients undergoing mechanical metatarsalgias from January to December 2013, with an average age of 57 years. Minimum follow-up was 1 year of evolution. Mechanical metatarsalgias were classified according to the stage of walking, second and third rocker. It was clinically assessed the disappearance of plantar keratosis, plantar pain when walking, as well as abandoning previous templates. Radiographically the metatarsal formula and consolidation of the osteotomy were evaluated. Results: in second rocker metatarsalgias, 90 percent had good or excellent results with 10 percent complications, mainly transfer metatarsalgia. In third rocker metatarsalgias 85 percent had good or very good results and 15 percent complications, mainly the transfer metatarsalgia. Conclusions: percutaneous distal osteotomies appear to be an acceptable technique for mechanical metatarsalgias treatment to provide good clinical and radiological results. Learning curve is important since it is not free of complications(AU)
Introduction: les métatarsalgies mécaniques de nature réfractaire exigent un traitement chirurgical. Nous présentons ici notre expérience avec la chirurgie percutanée. Objectif: le but de ce travail est de montrer l'efficacité des ostéotomies distales percutanées dans le traitement des métatarsalgies de type mécanique. Méthode: une étude rétrospective de 100 patients (âge moyen de 57 ans) atteints de métatarsalgies d'origine mécanique a été réalisée entre janvier et décembre 2013. Le suivi minimal a eu un an de durée. Les métatarsalgies mécaniques ont été classées selon phase de la marche (phase 2, second-rocker et phase 3, third-rocker). On a évalué du point de vue clinique la disparition des kératoses plantaires, la disparition de la douleur plantaire au cours de la marche et l'abandon des semelles, et du point de vue radiographique la formule métatarsienne et la consolidation des ostéotomies. Résultats: dans les métatarsalgies de second-rocker (métatarsalgies statiques), on a obtenu de bons et très bons résultats (90 pourcent) et très peu de complications (10 pourcent) telles que les métatarsalgies de transfert. Dans les métatarsalgies de third-rocker (métatarsalgies propulsives), on a obtenu de bons et très bons résultats (85 pourcent) et très peu de complications (15 pourcent), telles que les métatarsalgies de transfert. Conclusions: l'ostéotomie distale percutanée semble être la technique appropriée pour le traitement des métatarsalgies mécaniques, car elle prodigue de très bons résultats cliniques et radiologiques. L'apprentissage est très important, parce que cette technique n'est pas exceptée de complications(AU)

For metatarsalgia and lesser toe deformities, a commonly performed procedure is the Weil osteotomy, which inevitably depresses the metatarsal head, changing the intrinsic muscle axis and generating phalanx extension. The objective of this study is to present a new metatarsal osteotomy that shortens or lengthens and elevates the metatarsal head, the elevating metatarsal osteotomy (EMO), with its geometrical analysis and possible applications. A geometrical model was designed, planning an oblique subcapital osteotomy with slice resection and distal displacement. A trigonometric analysis was done to calculate how to shorten, elevate, or lengthen the metatarsal head. The EMO elevates the head in one-third of the width of the resected slice. Distal and dorsal displacement of the metatarsal head results in an elevation and lengthening of the metatarsal bone (60% elevation and 65% lengthening). Performing an elevating metatarsal osteotomy will lengthen and elevate the metatarsal head, which sometimes is necessary when treating toe deformities and instability.

BACKGROUND: Anatomical dissection of the second metatarsophalangeal (MTP) joint suggests that the plantar plate is the major stabilizing structure of the joint due to its central location and multiple important attachments. Many surgical procedures have been recommended when conservative treatment has failed, but some have had limited clinical success. The aim of our prospective study was to show the results obtained in the treatment of a group of patients with plantar plate tears by direct repair through a dorsal approach combined with a Weil metatarsal osteotomy with a minimum followup of 12 months. METHODS: We prospectively treated 28 patients (55 MTP joints) with lesser MTP joint instability, but only 22 patients (40 MTP joints) were treated by the direct repair of the plantar plate and were included in the study. All of them had initial complaints of acute forefoot pain with the subsequent development of deformity and instability of the MTP joints. All patients were evaluated clinically, radiographically, (plain radiographs and MRI exam), and by MTP joint arthroscopy. With this data, a direct correlation between the clinical staging and the anatomical grading for plantar plate dysfunction of each patient was determined RESULTS: The plantar plate of the second MTP joint was the most commonly affected joint (63%), and Grade III type tear (transverse and/or longitudinal extension tear) was the most frequent type. With the surgical treatment, we were able to markedly improve the parameters studied (pain, medial or dorsomedial deviation of the toe, joint stability, muscle balance, and joint congruence) to acceptable levels, The AOFAS score improved substantially from an average of 52 points preoperatively to 92 points postoperatively. CONCLUSION: The direct plantar plate repair combined with a Weil osteotomy and lateral soft tissue reefing can restore the normal alignment of the MTP joint. We have demonstrated that the anatomic repair of the plantar plate can correct the deviation of the affected toe (medial, dorsal, dorsomedial or dorsolateral), which lead to diminished pain with improved functional scores.
