OBJECTIVE: This is a retrospective study showing the incidence, type and extent of injuries occurring in the foot and/or ankle as a result of recreational sports practice. METHODS: We treated 131 patients, of which 123 were male and 8 female, with a history of trauma and pain in the foot and/or ankle after the practicing recreational sports. The average age of the male patients was 24.53 years. The evaluation was done through a research protocol, which contained the variables age, sex, diagnosis, and type of recreational sport. RESULTS: The sports were classified according to the American Medical Association, which divides them into contact and non-contact sports. 82.4% of the sample practiced contact sports, while 17.6% practiced sports classified as non-contact. CONCLUSIONS: The sprained ankle was the most frequent type of injury, especially those of grade I and II. Soccer was the sport responsible for the highest incidence of injuries and among its various forms the indoor soccer presented the highest frequency of injuries (35%). In the non-contact sports, the highest incidence was found in running. Level of Evidence IV, Case Series.

Objective To evaluate outcomes of 229 idiopathic clubfeet (ICF) treated using the Ponseti method, from 2001 to 2011, comparing two groups with different follow-ups. Method 155 patients (229 ICF) were treated separated in two groups: Group I: 72 patients (109 ICF – 47.6%) with a follow up of 62 to 128 months (mean of 85). Group II: 83 patients (120 ICF – 52.4%) with a follow up of 4 to 57 months (mean of 33.5). We have considered satisfactory outcomes for cases which correction of all deformed components, without surgery. Results Mean age for the initial assessment was 5.4 months in Group I and 3.2 in Group II. Satisfactory outcomes were obtained in 85.4% in Group I and 97.5% in Group II. Mean cast placements were 9.5 in Group I and 7 in Group II. 67% were submitted to percutaneous Achilles tenotomy in Group I and 65% in Group II. Deformity relapses, when using abducted braces, occurred in 41 (37.6%) feet from Group I; 11 were treated surgically. In Group II, 17 feet relapsed (14.1%); three of them were submitted to surgery. Conclusion The method was successful in both groups, in low number of complications. The results were statistically superior in Group II when deformity correction, cast placements, relapses and surgery indication.

Objective: To evaluate the postoperative results of patients who underwent surgical treatment of hallux valgus with a modified Reverdin-Isham (RI) technique and to compare the achieved correction with that reported by studies using the original technique. Methods: This is a retrospective study with patients with mild to moderate hallux valgus who underwent surgery from June 2010 to July 2019. All patients were operated using the modified RI technique. Data were collected through the American Orthopaedic Foot and Ankle Society (AOFAS) questionnaire, in addition to pre and postoperative radiographic studies of the intermetatarsal angle (IMA), the hallux valgus angle (HVA), and the distal metatarsal articular angle (DMAA). Results: The mean postoperative follow-up was 30.1 months, and the mean age of patients was 56.4 years. The median AOFAS score in the postoperative period was increased by 56 points. The mean HVA was reduced in 16.5°, the mean IMA was reduced in 4.3°, and the mean DMAA was reduced in 10°. There were no cases of displacement or deviation of the first metatarsal head during the postoperative follow-up. Conclusion: The modified RI technique provided considerable stability to the osteotomy, in addition to a significant correction of the measured angles and an improvement in AOFAS scores, demonstrating itself as an effective technique for correcting mild to moderate hallux valgus.

Objective: To analyze the effectiveness of peripheral nerve blocks in the ankle in percutaneous forefoot surgery and their potential complications. Methods: Retrospective study with a survey of the medical records of patients who underwent percutaneous orthopedic surgery onthe forefoot between 2009 and 2015, performed by the orthopedic foot  and ankle surgery group of our hospital, in which 4-in-1 and 5-in-1 anesthetic nerve blocks were used. We evaluated 239 cases, consisting of 222 female and 17 male subjects with a mean age of 61.2 years, seeking to observe the effectiveness and potential complications of the anesthetic technique. Results: Complications were observed in 3.34% of the 239 patients, with seven cases of neuritis and one case of tachycardia. Regarding the anesthetic technique, there were nine cases of block failure (3.76%), with four cases requiring supplementary local anesthetic, one case spinal anesthesia, and four cases general anesthesia. Conclusion: Having observed the low rate of complications and the almost complete success of 5-in-1 blocks in percutaneous forefoot surgery, we concluded that it is a safe and effective anesthetic technique. Level of Evidence IV, Therapeutic Study; Case Series.

Objective: The objective of this study was to analyze and compare the effectiveness of two types of abduction orthotics used for the feet, the Denis-Browne type (traditional) and the Dobbs type (dynamic), with regard to maintenance of deformity correction and prevention of recurrence . Method: In this comparative retrospective case study, information was collected from the medical records of children with idiopathic congenital clubfoot (CCF). We evaluated a total of 43 feet in 28 patients, which were divided into two groups. Group 1 was comprised of 16 patients with a total of 24 CCFs treated with the traditional orthotic device. Group 2 consisted of 12 patients with a total of 19 CCFs treated with the dynamic orthotic device. The statistical analysis used the ANOVA test to compare the categorical variables between the groups. A significance level of 5% was adopted (p-value≤0.05) . Results: In Group 1, recurrence was observed in 2 feet (8.33%), and in 1 foot in Group 2 (5.26%). No significant difference in effectiveness was seen between the two types of orthotic devices . Conclusion: Both abduction devices were seen to be effective in maintaining correction of congenital clubfoot deformities. There was no statistical significance between type of orthotic device and recurrence. Level of Evidence III, Retrospective Comparative Study.

OBJECTIVE: To clinically and radiographically compare the results of treatment of hallux valgus, by two addition osteotomy techniques: one using resected exostosis, and the other using a plate fixation for addition wedge. METHODS: We evaluated 24 feet of 19 patients, mean age 51.3 years, affected by hallux valgus, with a mean follow-up of 50.1 months. 13 feet underwent addition osteotomy with resected exostosis (AORE) and 11 patients (11 feet) underwent addition osteotomy with plate (AOP). The AOFAS score, intermetatarsal 1 and 2 angles, and hallux valgus angle were evaluated before and after surgery. RESULTS: In the AORE technique, the mean preoperative AOFAS was 46.6, with IMA 14o and HVA 32o, while in the postoperative AOFAS it was 81.3, with IMA 9o and HVA 25o, and 92.3% satisfactory results. In the AOP technique, the mean preoperative AOFAS was 42.1, with IMA 15o and HVA 29o while in the postoperative AOFAS it was 77.4, with IMA 11o and HVA 23o and 81.8% of satisfactory results. CONCLUSIONS: Both techniques proved to be effective in the treatment of hallux valgus, both clinically and radiografically, with no statistical difference between them.
