Preoperative antibiotic prophylaxis and the incidence of surgical site infections in elective clean soft tissue surgery of the hand and upper limb: a systematic review and meta-analysis.

BACKGROUND: Surgical site infections (SSI) are the most frequent early complications of hand surgeries. However, the indications still remain uncertain for antibiotic prophylaxis in elective clean soft tissue surgeries of the hand and upper limb. Therefore, a systematic review of the literature and a meta-analysis was conducted to investigate the impact of antibiotic prophylaxis on the prevention of SSI in these types of surgeries. METHODS: An electronic search was performed in the following databases: MEDLINE/Pubmed, PMC/Pubmed, Web of Science/Clarivate Analytics, Embase/Elsevier, Scopus/Elsevier, BVS/Lilacs, and the Cochrane Library, with no restrictions regarding publication language or date. The primary outcome of interest was the occurrence of SSI following elective clean soft tissue surgeries of the hand and upper limb according to the administration of preoperative antibiotic prophylaxis and no antibiotic prophylaxis. Surgeries involving simultaneous bone procedures or orthopedic implants were excluded. Study selection and data extraction were conducted independently by two reviewers. RoB 2.0 and ROBINS-I are Cochrane risk-of-bias tool for randomized trials and non-randomized studies of interventions. The magnitude of the intervention effect was estimated using the relative risk (RR). The meta-analysis was performed with the Review Manager and R software tools, using the Mantel-Haenszel random-effects model and a 95% confidence interval (CI). Results with p ≤ 0.05 were considered statistically significant. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. RESULTS: The initial search yielded 1175 titles, from which 12 articles met the inclusion criteria for the systematic review, and 10 were included in the subsequent meta-analysis. The majority of these studies were nonrandomized intervention trials, exhibiting a moderate risk of bias. According to our review, preoperative antibiotic prophylaxis did not have a statistically significant impact on the incidence of SSI (RR = 1.13, 95% CI 0.91-1.40, p = 0.28). The overall quality of evidence for this outcome was rated as low. Moderate statistical heterogeneity was observed (I2 = 44%), and the prespecified sensitivity analysis highlighted the consistency of the results. CONCLUSIONS: While these results were consistent with the findings from individual studies included in this review, it is important to note that, given the threshold of p ≤ 0.05 for statistical significance, no definitive conclusions can be drawn from the quantitative analysis of the data obtained. LEVEL OF EVIDENCE: Level 2. TRIAL REGISTRATION: CRD42023417786.

IMPLEMENTATION OF OTTAWA ANKLE RULES IN UNIVERSITY HOSPITAL EMERGENCY ROOM: PILOT STUDY.

Ankle injuries are the most common musculoskeletal injuries in emergency rooms and are associated with a great social and economic impact. The need to request additional tests for ankle sprains is based on suspicion of fracture. The Ottawa Ankle Rules (OAR) establish criteria for ordering radiographs to avoid performing unnecessary examinations. OBJECTIVE: To evaluate the implementation of the Ottawa Rules as a protocol for treating ankle sprains in the emergency department of a university hospital. METHODS: This is a retrospective observational study, conducted over a period of three months before and three months after implementation of the protocol. RESULTS: In the first phase, all patients complaining of ankle sprain underwent radiographs. In the second phase, after the application of the OAR, out of 85 patients evaluated, only 58 underwent complementary exams, showing a reduction of 31.8% in the request for imaging exams. There was no significant difference in fracture detection between the two groups (p=0.476). CONCLUSION: The OAR can be used as a tool in diagnosing ankle sprains, and their implementation reduced the request for imaging exams. Level of Evidence III, Retrospective Comparative Study.

Plantar Vein Thrombosis in a Patient with COVID-19: Case Report.

Plantar thrombophlebitis is a rare abnormality with few cases reported in the literature. Coexistence with severe acute respiratory syndrome coronavirus 2 infection increases its relevance. The disease is generally classified as idiopathic, and it is suggested that it is attributed to conditions that lead to hypercoagulability. We present the case of a 68-year-old female patient with thrombosis of the lateral plantar veins and a diagnosis of coronavirus disease of 2019. The plantar vein thrombosis diagnosis was made by means of Doppler ultrasonography and magnetic resonance imaging. Severe acute respiratory syndrome coronavirus 2 infection was suspected per clinical information and confirmed with reverse-transcriptase polymerase chain reaction technique. Treatment was successful using rivaroxaban and nonsteroidal antiinflammatory drugs.

ARTHROSCOPIC FOOT AND ANKLE SURGERY: BRAZILIAN SURGEON PROFILE.

Objective: To study the profile of the practice of arthroscopy among ankle and foot surgeons in Brazil and its evolution in recent years. Methods: Observational, cross-sectional study, using a survey sent to all members of the Associação Brasileira de Medicina e Cirurgia do Tornozelo e Pé (ABTPé) in 2017 and 2019. Results: In total, 75 surgeons participated in 2017 and 82 in 2019 and most had over 10 years of experience. Of these, 56 participants in 2017 (75%) and 68 in 2019 (82%) used arthroscopy. The number of specialists with no to five years of experience (p = 0.027) and who learned the technique during fellowship (p = 0.007) increased. The use of the 4.0 mm optics and 30° optics (p = 0.040) increased whereas the routine use of traction (p = 0.049) and radiofrequency (p = 0.002) decreased. The main pathology treated with anterior ankle arthroscopy was bone injury. The most frequent complication was neuropraxia. Conclusion: Most of the foot and ankle surgeons who use arthroscopy have more than 10 years of experience, performed anterior access, and are concentrated in the Southeast region of the country. The number of younger surgeons who learned the technique during fellowship increased. Level of Evidence III, Cross-Sectional Comparative Study.

RELIABILITY OF WIRELESS INSOLE BAROPODOMETRY OF NORMAL INDIVIDUAL'S GAIT.

OBJECTIVE: The plantar pressure distribution can be assessed quantitatively by computerized baropodometry such as carpet or insole. An insole-type system with wireless transmission was developed and plantar pressure results were previously validated by force platform. However, the reproducibility of the system had not been determined. Our objective was to evaluate the reliability of the results in different gait cycles, clinical characteristics and in different plantar anatomical sites. METHODS: 41 healthy adults (age, 34 ± 13 years; body mass index, 25 ± 5 kg/m2; 26 [63%], male, 26 [63%] practicing physical activity) were evaluated. Baropodometer evaluations were performed in 3 walking cycles with 100 m each, and the reliability between the cycles was examined. Pressure points on the heel, first metatarsal, fifth metatarsal and total plantar pressure were analyzed and compared. RESULTS: Moderate agreement was identified between the second and third cycles (ICC, 0.66; 95% CI, 0.14-0.83). Physical activity practitioners showed higher total plantar pressure (70.8 vs 68.2 Kpa; p = 0.04) and higher pressure in the heel (70.7 vs 68.1 Kpa; p = 0.036) in relation to sedentary ones. CONCLUSION: The insole was able to assess plant pressure with moderate reliability from the adaptation period. Level of Evidence III, Case control study - Investigating a diagnostic test.

OBJETIVO: A distribuição da pressão plantar pode ser avaliada quantitativamente por baropodometria computadorizada tipo tapete ou palmilha. Um sistema tipo palmilha com transmissão sem fio foi desenvolvido, cujos resultados de pressão plantar foram previamente validados por plataforma de força. No entanto, a reprodutibilidade do sistema não havia sido determinada. Nosso objetivo foi avaliar a confiabilidade dos resultados em relação a diferentes ciclos de marcha, características clínicas e em diferentes sítios anatômicos plantares. MÉTODOS: Foram avaliados 41 adultos saudáveis (idade, 34 ± 13 anos; índice de massa corpórea, 25 ± 5 kg/m2; 26 [63%], sexo masculino, 26 [63%] praticantes de atividade física). Avaliações com o baropodômetro foram realizadas em 3 ciclos de marcha com distância de 100 m, e avaliada a concordância entre os ciclos. Pontos de pressão no calcanhar, primeiro metatarsal, quinto metatarsal e a pressão plantar total foram analisados e comparados. RESULTADOS: Houve moderada concordância entre o segundo e terceiro ciclos (CCI, 0,66; IC95%, 0,14-0,83). Praticantes de atividades físicas apresentaram pressão plantar total (70,8 vs 68,2 Kpa; p = 0,04) e no calcanhar (70,7 vs 68,1 Kpa; p = 0,036) aumentada em relação aos sedentários. CONCLUSÃO: A palmilha foi capaz de avaliar a pressão plantar com confiabilidade moderada a partir do período de adaptação.

Reliability of Two Smartphone Applications for Radiographic Measurements of Hallux Valgus Angles.

The objective of the present study was to assess the reliability of 2 smartphone applications compared with the traditional goniometer technique for measurement of radiographic angles in hallux valgus and the time required for analysis with the different methods. The radiographs of 31 patients (52 feet) with a diagnosis of hallux valgus were analyzed. Four observers, 2 with >10 years' experience in foot and ankle surgery and 2 in-training surgeons, measured the hallux valgus angle and intermetatarsal angle using a manual goniometer technique and 2 smartphone applications (Hallux Angles and iPinPoint). The interobserver and intermethod reliability were estimated using intraclass correlation coefficients (ICCs), and the time required for measurement of the angles among the 3 methods was compared using the Friedman test. A very good or good interobserver reliability was found among the 4 observers measuring the hallux valgus angle and intermetatarsal angle using the goniometer (ICC 0.913 and 0.821, respectively) and iPinPoint (ICC 0.866 and 0.638, respectively). Using the Hallux Angles application, a very good interobserver reliability was found for measurements of the hallux valgus angle (ICC 0.962) and intermetatarsal angle (ICC 0.935) only among the more experienced observers. The time required for the measurements was significantly shorter for the measurements using both smartphone applications compared with the goniometer method. One smartphone application (iPinPoint) was reliable for measurements of the hallux valgus angles by either experienced or nonexperienced observers. The use of these tools might save time in the evaluation of radiographic angles in the hallux valgus.

Avaliação da reprodutibilidade da classificação de Sanders para fraturas do calcâneo / Assessment of reproducibility of sanders classification for calcaneal fractures

Objetivo: Avaliar a reprodutibilidade intra e inter observadores da Classificação Tomográfica de Sanders das fraturas do calcâneo entre observadores mais e menos experientes em cirurgia do pé e tornozelo.Métodos: Foram avaliadas imagens tomográficas de 46 pacientes com diagnóstico de fratura do calcâneo. Quatro observadores, dois com dez anos de experiência em cirurgia do pé e tornozelo e dois residentes do terceiro ano em Ortopedia e Traumatologia classificaram as fraturas independentemente. Após três semanas, os mesmos observadores classificaram as fraturas apresentadas em ordem alterada aleatoriamente.A concordância intra e inter observadores foi analisada através do índice Kappa. Resultados: Houve boa concordância intra observador para os dois observadores mais experientes e um observador menos experiente (valores de Kappa 0,640; 0,632 e 0,629, respectivamente). Quando analisada a concordância inter observador, houve concordância fraca entre os mais experientes (Kappa = 0,289) e moderada entreos menos experientes (Kappa = 0,527). Conclusões: A Classificação Tomográfica de Sanders apresentou boa concordância intra observador,porém reprodutibilidade inter observadores abaixo da ideal, tanto entre observadores mais experientes quanto aqueles menos experientes.Nível de Evidência III, Estudos Diagnósticos.

Objective: To assess intra- and interobserver reproducibilityof Sanders Classification System of calcaneal fracturesamong experienced and less experienced observers. Methods:Forty-six CT scans of intra-articular calcaneal fractureswere reviewed. Four observers, two with ten years ofexperience in foot and ankle surgery and two third-year residentsin Orthopedics and Traumatology classified the fractureson two separate occasions three weeks apart from eachother. The intra and inter-observer reliability was analyzedusing the Kappa index. Results: There was good intraobserverreliability for the two experienced observers and oneless experienced observer (Kappa values 0.640, 0.632 and0.629, respectively). The interobserver reliability was fairbetween the experienced observers (Kappa = 0.289) andmoderate among the less experienced observers (Kappa= 0.527). Conclusions: The Sanders Classification Systemshowed good intraobserver reliability, but interobserver reproducibilitybelow the ideal level, both among experiencedand less experienced observers.

Endoscopic treatment of the posterior ankle impingement syndrome on amateur and professional athletes.

PURPOSE: To determine whether professional and amateur athletes showed differences in ankle function when treated with endoscopic technique for posterior ankle impingement syndrome, to verify the impact of the presence of associated lesions in clinical evolution and to assess time to return to sport (we hypothesize that time will be the only difference between groups). METHODS: Thirty-two athletes with a diagnosis of posterior impingement syndrome underwent surgery endoscopically. The American Orthopaedics Foot and Ankle Society (AOFAS) scale was used to compare functional results between amateur (15) and professional athletes (17). The satisfaction, time to return to sport, operative time, intraoperative findings and complications were evaluated, and the presence of associated injuries interfering in these results was verified. RESULTS: The preoperative AOFAS score range for the professional group was 62.9 ± 14 preoperatively and 92.3 ± 7.7 postoperatively, and for the amateur group was 67.9 ± 19.7 and 94 ± 9.3. The satisfaction was excellent or good in 94 % of all cases and fair in 6%. The average time of surgery was 48.3 + 25 min. Bone involvement was present in 100% of cases and complications in three cases. Time to return to sports was similar (n.s.) in both groups, and the mean time was 15.6 ± 13.7 and 16.3 ± 9 weeks, respectively. CONCLUSION: No significant difference regarding functional results and time to return to sports between professionals and amateur athletes operated was found. Athletes showed mainly good and excellent results and low complication rate. The presence of associated injuries did not significantly influence the results. With these results, the high-level athlete can better programme their surgeries so they can fully recover and perform better in the most important competitions. LEVEL OF EVIDENCE: Level III.

Tension band wiring for proximal femoral varus osteotomy fixation in children.

For proximal varus osteotomy of the femur in children, a stable fixation, is a concern regarding the safety and the protection of the surgery. The methods of fixation are mostly represented by plating systems; however, the tension band wiring is a simple and eligible option for fixation of proximal femur osteotomy. The purpose of this retrospective case series study is to evaluate outcomes and bone remodelation after using the tension band wiring technique to fixate proximal femoral varus osteotomies in children.The study enrolled 20 patients who underwent femoral varus osteotomy to treat Legg-Calvé-Perthes disease and other causes of necrosis of the femoral head. The mean patient age at the time of surgery was 7.4 ± 2.3 years (range, 4.3-13.8 y), and the follow-up period averaged 10 ± 4.3 years (range, 4.7-20.8 y). To assess the effects of the osteotomy at the neck-shaft angle and its evolution over time, radiographs obtained preoperatively and during the follow-up were analyzed. The neck-shaft angle was measured independently by 2 observers, and intraclass correlation coefficients (ICCs) were assessed for reliability.The ICC analysis showed good reliability. There was a significant reduction in the neck-shaft angle (P < 0.001) between the preoperative and the immediate postoperative periods, with an estimated difference of 14.3°. Between the immediate and the early postoperative periods, the estimated difference was 2.1°, which indicated a significant increase in the neck-shaft angle (P = 0.003). Between the early postoperative period and the final evaluation, there was a significant increase (P < 0.001), with an estimated difference of 7.0°. No implant failures or other complications were observed, but 1 case of peri-implant femoral fracture occurred >17 years postsurgery.The tension band wiring technique proved to be a simple and effective method for fixating proximal femoral varus osteotomy in children.The level IV is appropriated for our study (case series, retrospective).
