A Case Report of Tarsal Navicular Body Fracture with Lateral Ankle Ligament Complex Tear – a New Injury Combination

Introduction: Fractures of tarsal navicular bone are a rare injury. A navicular fracture can occur either in isolation or associated with other bony or ligamentous injuries, depending on the severity and mechanism of trauma at the time of impact. We report a previously undescribed injury combination of navicular fracture with tear of the lateral ankle ligament complex. Case Report: An 18-year-old professional long jump athlete presented with a history of twisting injury immediately before taking off, while attempting a jump. A detailed clinical examination and radiological assessment with computed tomography (CT) and magnetic resonance imaging (MRI) scan were performed. She was diagnosed to have a navicular body fracture with complete rupture of anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL). Acute fixation of navicular body fracture along with primary repair of ATFL and CFL was done. The final outcome of the patient was good with return to unrestricted physical activities after 4 months. Conclusion: A new injury combination of navicular fracture along with lateral ankle ligament complex tear is reported in a professional athlete. A high index of clinical suspicion and early detection using CT and MRI scan can identify this rare injury combination. Surgical treatment can result in favorable outcomes.

Epidemiology of Injuries in National Collegiate Athletic Association Women's Volleyball: 2014–2015 Through 2018–2019

Context Women's volleyball is a globally popular sport with widespread participation at the National Collegiate Athletic Association (NCAA) level. Background Routine examinations of NCAA women's volleyball injuries are important for recognizing emerging injury-related patterns in this population. Methods Exposure and injury data collected in the NCAA Injury Surveillance Program during the 2014–2015 through 2018–2019 athletic years were analyzed. Injury counts, rates, and proportions were used to describe injury characteristics, and injury rate ratios were used to examine differences in injury rates. Results The overall injury rate was 6.73 per 1000 athlete-exposures. Knee (14.6%) and ankle (13.8%) injuries accounted for the largest proportion of all reported injuries, and most injuries were attributed to overuse (26.1%) or noncontact (22.7%) mechanisms. Lateral ankle ligament complex tears (11.1%) and concussions (7.3%) were the most commonly reported specific injury. Summary Results indicate an increasing burden of practice-related injuries and the need to further examine overuse injuries. Lower-extremity injury prevention strategies and mechanisms of concussion also warrant further attention.
