The patients were treated with proximal end metatarsal osteotomies fixed with metallic wires, staples or compression plates with and without grading. Treated comorbidities included hallux valgus deformity, splayfoot, hallux rigidus, pes cavus, hammertoe, crossover toe and plantar plate repair. The patients were evaluated using the AOFAS lesser toes.  Results: The AOFAS score improved from 34.5 points (±12.5) preoperatively to 88.9 points (±7.9) postoperatively (p<0.0001). One patient developed a late infection in the foot that was controlled with antibiotics; although the correction of the second toe was partially lost, an acceptable transversal arch was maintained. In all cases except for the infection, no metatarsalgia recurrence or change in the deformity of the corresponding toes occurred.  Discussion: Surgical treatment aimed to improve the mechanical distribution of weight and to stabilize the transversal arch, thereby reducing metatarsalgia. The forefoot was stabilized by sufficient shortening and/or lifting to treat metatarsalgia, especially in the 2nd and 3rd rays. We also aimed to achieve complete flexibility of the metatarsophalangeal joints with good alignment. The favorable outcome of this method is comparable to that of the study by Aiello, who achieved good outcomes in 84.9% of 45 feet, whereas our study showed good outcomes in 96% of 29 feet.  Conclusion: Proximal metatarsal osteotomies with fixation with metal implants for metatarsalgia treatment showed satisfactory outcomes in 96% of operated cases. We believe that this procedure is effective and safe and has a high rate of patient satisfaction.","PeriodicalId":21602,"journal":{"name":"Scientific Journal of the Foot & Ankle","volume":"92 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91260020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The search was performed in the electronic databases Cochrane Database of Systematic Reviews (CDSR), Medline and Lilacs and in the PROSPERO international prospective register of systematic reviews, with no language or publication date restriction. The most recent search was performed on June 1, 2018. The term “ankle fracture” was used in those databases. Pubmed was also searched, using the [Mesh] term. The inclusion criteria were systematic reviews on the treatment of malleolar ankle fractures in adults. Results: Twenty-two systematic reviews were identified in the searched databases. Systematic reviews on the multiprofessional treatment of patients with malleolar fractures addressed the selection of metallic syndesmotic screw rather than absorbable screw without indicating its removal in the absence of symptoms. Furthermore, the Adelaide Fracture in the Diabetic Ankle (AFDA) algorithm was established for the diagnosis and treatment of diabetic patients. There is still no evidence that arthroscopically assisted open reduction and internal fixation (ORIF) is the best therapeutic method, nor is there biomechanical evidence that the locking plate is better than the conventional plate for treating lateral malleolar fracture in elderly people. There is strong evidence that mobility and early weight-bearing directly affect the functional prognosis of patients. Conclusion: This study was extremely important for identifying and selecting the most recent systematic reviews on the topic, thereby guiding practices regarding the best therapeutic regimen for patients with malleolar fractures.","PeriodicalId":21602,"journal":{"name":"Scientific Journal of the Foot & Ankle","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85847292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this paper is to evaluate the functional outcome of professional soccer players undergoing surgical treatment of Dameron’s zones II and III fifth metatarsal fractures with an intramedullary screw with or without bone graft. Methods: Thirty-four professional soccer players underwent operations from July 2001 to June 2016. All of them underwent an evaluation based on AOFAS and VAS scores before and after surgery, with a mean follow-up of 24 months. The need for grafting was evaluated in relation to the time for surgery. Additionally, the influence of time to surgery, fracture union, Torg’s classification and grafting were related to the time to return to sports. In addition, the player's position, age, complications and side of the lesion were also described. Results: There were 10 forwards, 07 center forwards, 06 full-backs, 05 midfielders, 03 defenders, 02 goalkeepers and 01 central defender, with an average of 19 years; the right side was affected in 44% of cases. The AOFAS average pre and postoperatively was 42 and 99, respectively, while the EVA was 6 and 0. The longer delay to operate, the greater was the need for grafting (p = 1.11%), each day increasing by 1,015 times the need for grafting. The return to activities was not influenced by the time to operate, time to union, Torg’s classification or graft use.

In contrast to fatigue or stress fractures, which affect normal bones and have been extensively studied in the literature, foot and ankle insufficiency fractures have been poorly researched to date. The objective of this study was to identify behavioral, biomechanical and metabolic factors associated with the development of foot and ankle insufficiency fractures. Methods: In total, 53 sedentary postmenopausal female patients who had foot and ankle insufficiency fractures and who were treated at the São Paulo State Civil Servant Hospital (Hospital do Servidor Público do Estado de São Paulo) were included in the treatment group, and 53 individuals were included in the control group. Data were collected on fracture site, body mass index (BMI), corticoid use, femoral and lumbar T-score measured by bone densitometry, and serum 25-hydroxyvitamin D level. The calcaneal angle, the angle between the first metatarsal and the talus and the metatarsus adductus angle were measured in radiographs. Results: The fractures affected the metatarsal bones in 47 patients. Other fracture sites included the lateral malleolus, lateral cuneiform bone, cuboid bone, tibia and calcaneus. All metatarsal bones were affected, most frequently the 5th. The most common fracture was a 5th metatarsal base fracture in zone II. There was no significant difference in mean BMI, serum 25-hydroxyvitamin D levels, alcohol consumption or smoking between the groups. The development of fractures was significantly associated with corticoid use (p<0.0001), low femur (p=0.028) and lumbar spine (p=0.002) bone mineral density and metatarsus adductus angle (p=0.02). When analyzed separately, 4th and 5th metatarsal fractures were associated with smaller angles between the talus and the first metatarsal (p=0.01). Conclusion: Foot and ankle insufficiency fractures among sedentary postmenopausal women are associated with corticoid use, low bone mineral density and biomechanical characteristics, such as pes cavus and metatarsus adductus. The presence of such fractures may be the first sign of bone fragility and should be used as criteria for initiating adequate treatment to prevent other fractures.","PeriodicalId":21602,"journal":{"name":"Scientific Journal of the Foot & Ankle","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85219932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonunion remains an important complication, with an incidence and role of risk factors varying in the literature. Recent reports have highlighted a decrease in overall union rates between 96% and 100% to 84%, further strengthening the need for an understanding of risk factors that may be implicated in nonunion rates. Some possible factors have been identified, including smoking, revision surgery, the presence and extent of devascularized bone, and previous ankle joint fusion. Current practice suggests that using bone grafts or bone graft substitutes decreases the risk of its occurrence. Objective: To compare union rates of isolated subtalar arthrodesis with and without the use of bone grafts or bone graft substitutes. Methods: We retrospectively reviewed 135 subtalar fusions with a mean follow-up of 18 ± 14 months. The standard approach was used for all operations. Graft materials included β-tricalcium phosphate, demineralized bone matrix, iliac crest autograft and allograft and allograft cancellous chips. Successful subtalar fusion was determined clinically and radiographically. Results: There was an 88% (37/42) union rate without graft and an 83% (78/93) union rate with bone graft use. The odds ratio of union for graft versus no graft was 0.703 (95% CI, 0.237-2.08). The average time to union in the graft group was 3 ± 0.73 months and 3 ± 0.86 in the nongraft group, with no statistically significant difference detected (p = 0.56).

This study aimed to assess the early complications, reoperations, and radiographic and clinical outcomes of this novel implant. Methods: A retrospective analysis of 64 consecutive ankles that underwent a primary Infinity® TAA was performed. Patients had an average follow-up of 24.5 (range, 18-39) months. Medical records were reviewed to determine the incidence of complications, reoperations, and revisions. Additionally, patient-reported outcomes were analyzed with the Foot and Ankle Outcome Score (FAOS). Results: Survivorship of the implant was 95.3%. Fourteen ankles (21.8%) presented a total of 17 complications. A total of 12 reoperations were necessary in 11 ankles (17.1%). Revision surgery was indicated for 3 ankles (4.7%) as a result of subsidence of the implant. Tibiotalar coronal deformity was significantly improved after surgery (P < .0001) and maintained at the latest follow-up (P = .81). Periprosthetic radiolucent lines were observed around the tibial component in 20 ankles (31%) and around the talar component in 2 ankles (3.1%). A tibial cyst was observed in 1 ankle (1.5%). Outcome scores were significantly improved for all FAOS components analyzed (P < .0001). Conclusion: Most complications observed in the study were minor and successfully treated with a single reoperation procedure or nonoperatively.

The persistence of this condition can lead to progressive loosening of the medial containment structures, generating multidirectional rotational instability. Treatment of the deltoid complex through ligamentoplasty of its components has been proposed as a solution for these patients, and the arthroscopic technique is a currently described alternative. Methods: This is a retrospective study of 10 patients (11 ankles) diagnosed with multidirectional instability who underwent ankle arthroscopy with medial and lateral ligament reconstruction (arthroscopic Brostrom technique) from January 2017 to January 2019. All patients filled out an epidemiological questionnaire and were assessed for ankle pain and function using the Pain Visual Analog Scale (VAS) and the American Orthopedic Foot and Ankle Society (AOFAS) scale at the last follow-up evaluation, at a mean of 12 months (6-24 months). Results: All patients showed signs of associated medial instability during the arthroscopy. Four ankles had associated osteochondral injuries. One ankle also had associated syndesmotic instability. The mean AOFAS score was 82.6 at the last follow-up evaluation, and the mean VAS score was 2.1. No patient had complications related to surgery or loss of ankle mobility greater than 5 degrees (ankle or subtalar joint). Eight patients described the outcome as excellent, and 2 described it as good. All patients returned to sports after 6 months of follow-up. No complaints of instability or positive ligament tests were observed. Conclusion: Combined medial and lateral arthroscopic ankle ligamentoplasty is an effective and safe alternative for the treatment of multidirectional instability refractory to conservative treatment. The inclusion of the deltoid complex and the reduced invasiveness of this technique may improve the clinical outcomes of these patients.","PeriodicalId":21602,"journal":{"name":"Scientific Journal of the Foot & Ankle","volume":"155 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77122636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
