Abstract
PURPOSE: Ballistic fractures of the femoral condyles are rare injuries with limited literature to help guide treatment. The purpose of this study is to report on the presentation, management, and outcomes for patients with isolated ballistic condylar fractures. METHODS: Eighteen patients between ages 16 and 65 with low-energy ballistic injuries isolated to the femoral condyles (OTA 33B) were included, 15 with CT imaging. Clinical records and imaging were reviewed, as well as treatment strategy. Fractures were classified by AO/OTA classification. Outcome and follow-up data were gathered at outpatient appointments and telephone calls. RESULTS: Of the 18 patients, 78% were treated operatively (61% with open reduction and internal fixation, 17% with removal of foreign body alone). There were two instances of traumatic vascular injury and no neurologic injuries. Furthermore, there were no identified infections. Only 58% of the patients had follow-up for more than 6 weeks with average KOOS Jr. Score of 50, and average VAS pain score of 5.2. CONCLUSIONS: Ballistic femoral condyle fractures are rare Orthopaedic injuries seen in relatively high frequency at our institution. Most (78%) were treated operatively and with few complications. These fractures are not easily classified according to common classification schemes and may benefit from more rigorous study to guide treatment and anticipate outcomes.
