RESUMO
BACKGROUND: In response to the all-time high of female sports participation, there has been increasing scientific discourse and media interest in women's sporting injuries in recent years. In gender comparable sports the rate of foot and ankle injury for women is higher than for men. There are intrinsic and extrinsic factors which may explain this difference. METHODS: A systematic literature search was performed according to the PRISMA guidelines of PubMed, Ovid EMBASE and OVID MEDLINE. Relevant key terms were used to narrow the scope of the search prior to screening. Case reports, review articles, paediatric patients, non foot and ankle injuries and combat sports were excluded. We used dual author, two pass screening to arrive at final included studies. RESULTS: 2510 articles were screened after duplicate exclusion. 104 were included in this literature review. We identified lack of reporting gender difference in the literature.We identified that females have higher frequency and severity of injury. We provide an overview of our current understanding of ankle ligament complex injuries, stress fractures, ostochondral lesions of the talus and Achilles tendon rupture. We expand on the evidence of two codes of football, soccer and Australian rules, as a "case study" of how injury patterns differ between genders in the same sport. We identify gender specific characteristics including severity, types of injury, predisposing risk factors, anatomy, endocrinology and biomechanics associated with injuries. Finally, we examine the effect of level of competition on female injury patterns. CONCLUSIONS: There is a lack of scientific reporting of gender differences of foot and ankle injuries. Female athletes suffer foot and ankle injuries at higher rates and with greater severity compared to males. This is an under-reported, yet important area of orthopaedics and sports medicine to understand, and hence reduce the injury burden for female athletes.
RESUMO
Background: Tibiocalcaneal arthrodesis (TCA) can be achieved by internal fixation (intramedullary nail or plate), external fixation, or a combination. Evidence for the optimal approach is limited. This systematic review examines the outcomes of these different approaches to guide surgical management. Methods: A MEDLINE and Oxford SOLO search was performed using "tibiocalcaneal," "ankle," "fusion OR arthrodesis." The primary outcome was union. Secondary outcomes included rates of postoperative complications, weightbearing status, rates of revision surgery, and PROMs. We included any studies with follow-up greater than 6 months that contained our primary outcome and at least 1 secondary outcome. Results: The initial search yielded 164 articles, of which 9 studies totaling 53 cases met the criteria. The majority of articles were excluded because they were nonsurgical studies, or were not about isolated TCA but were for tibiotalocalcaneal arthrodesis, more complex reconstructions (eg, Charcot), case reports, and/or did not include the predetermined outcome measures.TCA union rate was 86.2% following external fixation, 82.4% for intramedullary nail fixation, and 83.3% for plate fixation. One patient underwent a hybrid of external and internal fixation, and the outcome was nonunion. The rate of complications following TCA was 69.8%. Conclusion: There is limited evidence on the best operative approach for isolated tibiocalcaneal arthrodesis. Both external and internal fixation methods had comparable union rates. External fixation had frequent complications and a more challenging postoperative protocol. Novel techniques such as 3D-printed cages and talus replacement may become a promising alternative but require further investigation.
