Abstract
Introduction Apophyseal avulsion fractures of the ischial tuberosity are rare injuries and therefore often not diagnosed in a timely manner. Healing may then result in massive hypertrophic ischial tuberosity. This can cause ischiofemoral impingement symptoms. Due to the low incidence and scarce literature, the optimal treatment and surgery is unclear.
Materials and Methods A literature search was carried out using the online medical database “PubMed”. The findings of the literature were then applied to a clinical case of delayed diagnosis of the apophyseal avulsion fracture of the ischial tuberosity.
Results There is no gold standard in the literature for the treatment of avulsion fractures on the ischial tuberosity. Nearly 90% are treated conservatively and a fragment dislocation of more than 2 cm is often the indication for surgical care. However, the surgical procedures described are very diverse. An ischiofemoral impingement symptom may result from excessive ossification of the ischial tuberosity, bringing the ischiofemoral distance to the critical limit of 2 cm.
Conclusions The timely correct diagnosis and initiation of a therapy is crucial for the later outcome of the patient. Ischiofemoral impingement symptoms may be the indication of bony displacement of the ischial tuberosity as a result of injury. Therapy is then surgical with partial resection of the ischial tuberosity and plate osteosynthesis.
