Resumen:This paper presents a comprehensive review on the current concept of the diagnosis and treatment of central metatarsalgia on the basis of medical literature analyses. Metatarsalgia is the term for pain in the forefoot. This is a set of symptoms corresponding to a wide range of diseases. Central metatarsalgia is a kind of metatarsalgia which arises from structural-functional changes that lead to excessive pressure in the area of metatarsal heads. The data analysis demonstrated that presently various types of osteotomies of metatarsal bones are the main surgical treatment options with the chance of complication ranging from 6 to 50%. Weil-osteotomy is known to be the most popular type of osteotomy for treatment of central metatarsalgia. The most common complication of Weil-osteotomy is floating toe, the one that doesn't contact with the supporting surface. In case Weil-osteotomy and intraphalangeal arthrodesis with trans acticular fixation are both performed, the complication of floating toe increases up to 50%. When Weil osteotomy, plantar plate repair, extensor digitorum longum tendon lengthening and triple Weil-osteotomy are performed simultaneously, the complication rate is 15% approximately which is much lower. Using combined osteotomy techniques as well as taking into account structural-functional pathologic changes of the forefoot and ligaments repair of metatarsalphalangeal joint will ensure the most successful development of surgical treatment techniques for central metatarsalgia.

Resumen: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.

Resumen:BACKGROUND: Failed hallux valgus surgery may result in residual or recurrent hallux valgus, and as well transfer metatarsalgia. The present technical tip concerns the combination of fusion of the first metatarsophalangeal (MTP) joint and lengthening of the first metatarsal (MT) through a scarf osteotomy. MATERIALS AND METHODS: Six patients underwent the presented technique, all for the indication of failed hallux valgus surgery with shortening of the first MT and degenerative changes in the 1st MTP joint. RESULTS: Follow-up at six months revealed all patients had complete healing of the osteotomy and arthrodesis sites. They were all asymptomatic and fully active, completely satisfied with the outcome. CONCLUSIONS: Combined fusion of the first MTP joint and lengthening of the first MT through a scarf osteotomy results in an excellent outcome in patients with failed hallux valgus surgery with shortening of the first MT and degenerative changes in the 1st MTP joint.

Resumen:The causes of metatarsalgia are classified as primary, secondary, and iatrogenic. Anatomical and biomechanical considerations separate "static" from "propulsive" forms of metatarsalgia. The physical examination should be combined with an assessment of weight-bearing radiographs and, if needed, of ultrasound or magnetic resonance imaging scans. The first-line treatment is conservative (stretching exercises, footwear modification, insoles, and lesion debridement). Soft-tissue surgical procedures (gastrocnemius muscle recession, tendon transfer, and plantar plate repair) should also be considered. Among the various types of metatarsal osteotomy, the Weil procedure is reliable. Percutaneous methods are being developed but require evaluation. A treatment algorithm can be developed based on whether the hallux is normal or abnormal. Metatarsalgia due to inflammatory disease requires a specific treatment strategy.

Resumen:BACKGROUND: For patients with hallux rigidus seeking a motion-sparing procedure, interposition arthroplasty is an alternative to fusion. The purpose of this study was to report patient outcomes after interpositional arthroplasty for hallux rigidus. METHODS: All patients undergoing interpositional arthroplasty at our institution from 2001 to 2014 were identified and a retrospective chart review was performed. Follow-up was conducted through a telephone survey to obtain survivorship, satisfaction, and functional scores. Survivorship of the interpositional arthroplasty procedure was defined as no subsequent surgery on the hallux after the index procedure. Patients were excluded for incomplete records. Complications were recorded. From 2001 to 2014, 183 patients were identified. Of these, 14 were excluded for incomplete data, leaving 169 patients. Of these, 133 had an average follow-up of 62.2 months (range, 24.3 months to 151.2 months). RESULTS: The overall failure rate was 3.8% (5/133). Patient-reported outcome was rated as excellent in 65.4% (87/133) or good in 24.1% (32/133) of patients and fair or poor in 10.5% (14/133) of patients. Of 133 patients, 101 (76%) were able to return to fashionable or regular footwear. The infection rate was 1.5% (2/133). Patient-reported cock-up deformity of the first metatarsophalangeal joint (MTPJ) occurred in 4.5% (6/133) of patients. In addition, 17.3% (23/133) of patients reported metatarsalgia of the second or third MTPJ at the time of final follow-up, and there was no significant difference between interposition types ( P = .441). CONCLUSION: Interpositional arthroplasty for hallux rigidus was found to have excellent or good results in most patients at a mean follow-up of 62.2 months. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Título:Biomechanical consequences of adding plantar fascia release to metatarsal osteotomies: Changes in forefoot plantar pressures.

Resumen:Destruction of the normal metatarsal arch by a long metatarsal is often a cause for metatarsalgia. When surgery is warranted, distal oblique, or proximal dorsiflexion osteotomies of the long metatarsal bones are commonly used. The plantar fascia has anatomical connection to all metatarsal heads. There is controversial scientific evidence on the effect of plantar fascia release on forefoot biomechanics. In this cadaveric biomechanical study, we hypothesized that plantar fascia release would augment the plantar metatarsal pressure decreasing effects of two common second metatarsal osteotomy techniques. Six matched pairs of foot and ankle specimens were mounted on a pressure mat loading platform. Two randomly assigned surgery groups, which had received either distal oblique, or proximal dorsiflexion osteotomy of the second metatarsal, were evaluated before and after plantar fasciectomy. Specimens were loaded up to a ground reaction force of 400 N at varying Achilles tendon forces. Average pressures, peak pressures, and contact areas were analyzed. Supporting our hypothesis, average pressures under the second metatarsal during 600 N Achilles load were decreased by plantar fascia release following proximal osteotomy (p < 0.05). However contrary to our hypothesis, peak pressures under the second metatarsal were significantly increased by plantar fascia release following modified distal osteotomy, under multiple Achilles loading conditions (p < 0.05). Plantar fasciotomy should not be added to distal metatarsal osteotomy in the treatment of metatarsalgia. If proximal dorsiflexion osteotomy would be preferred, plantar fasciotomy should be approached cautiously not to disturb the forefoot biomechanics. © 2016 Orthopaedic Research Society.

Resumen:BACKGROUND: The aim of the present study is to establish the relationship between foot-ankle patient-reported outcome measures (PROM) and three measures of foot-ankle alignment (MoFAA) in patients with metatarsal head pain. METHODS: A cross-sectional study where 206 patients completed three PROMs and a clinician recorded three MoFAA bilaterally (three times each). A reliability analysis of the MoFAA, a correlation analysis (between MoFAA and PROM) and regression analysis (dependent variable: PROM; independent variables: MoFAA) were performed. RESULTS: Pearson's coefficient changed in each PROM used, ranging from 0.243 (AAOS-FAM -FVA ) to 0.807 (FFI -first MTPJE ). Regression indices (R -corrected) ranged between 0.117 (AAOS-FAM ) and 0.701 (FFI ). CONCLUSIONS: The MoFAA correlated between moderately to strongly with the foot-ankle PROM selected. The level of correlation between MoFAA and PROM was higher when patients with metatarsal head pain were asked about foot health status, pain and function; however, the correlation was poor when the patient was asked about shoe aspects. In addition, the MoFAA variable that achieved the highest correlation value was the first metatarsophalangeal joint extension. The results obtained in this study could be used in future studies to develop tools for assessing and monitoring patients with metatarsal head pain.

Resumen:The traditional open surgical options for the treatment of metatarsalgia and lesser toe deformities are limited and often result in unintentional stiffness. The use of percutaneous techniques for the treatment of metatarsalgia and lesser toe deformities allows a more versatile and tailor-made approach to the individual deformities. As with all percutaneous techniques, it is vital the surgeon engage in cadaveric training from surgeons experienced in these techniques before introducing them into his/her clinical practice.
