Avulsion fracture of legamentum teres without dislocation: A case report and literature analysis

Abstract

Background: Femoral head avulsion fracture is a rare diagnosis in general and even rarer when it is identified without a dislocation.Case presentation: This is a case of 16 year old Female, not known to have any past medical nor surgical history, presented to our hospital as a case of motor vehicle accident, frontal collision at a speed of around 90km/h, she was a back seat passenger and she denied any history of head trauma, loss of consciousness nor amnesia, upon arrival in hospital assessment revealed an isolated lower back pain with bilateral hips pain, upon further examination the range of motion was restricted bilaterally in both hips due to pain, pan CT scan showed an avulsion fracture of the left femoral head.Conclusion: We usually relate femoral head fracture with hip dislocation, nevertheless a finding of legamentum teres avulsion fracture of the femoral head is by far extremely rare without a dislocation. The outcome of conservative management was successful with weight bearing precautions and early physiotherapy (PT) and range of motion (ROM).
