Kurzbeschreibung/Zielsetzung

Among all the bones in the foot the calcaneus is the most commonly fractured one, counting for 1 – 2% of all fractures. Calcaneus fractures are very complex injuries with regard to the damage of the bone, the cartilage of the subtalar joint and the soft tissues. The aim of this study is to review the mid- to longterm outcome (at least 2 years follow-up) of these operatively treated complex intra-articular calcaneus fractures in our institution. The clinical outcome, quality of life, rate of complications, rate of revision surgery, time to secondary subtalar fusion, time of inability to work after ORIF and primary subtalar fusion will be examined. Profound (statistical) analysis is expected to reveal risk factors for secondary subtalar osteoarthritis. If such risk factors can be determined they can be considered in the future. This might improve the outcome of (operatively) treated calcaneus fractures.
Study design: monocentric, retrospective study. After agreement to participate in the study the patients will receive the SF-36-Score questionnaire. At the time of follow-up examination, the AOFAS-Score will be completed by the investigator or subinvestigator, radiographic examination will be performed and the patient will be asked to complete the VAS. The clinical and radiographic data at the time of injury will be extracted from the patient's medical record.
Primary endpoint: Failure of initial treatment leading to arthrodesis.
