Patellar Subluxation with Osteochondral Fracture: A Case Report and Literature Review

髕骨脫位不全併髕骨骨折病例報告曁文獻回顧

摘要


肇因於急性創傷所致髕骨脫位不全併髕骨軟骨骨折之案例在急診室並不常見,病患在創傷後若主訴膝蓋髕骨周圍附近腫痛常需考慮是否為膝蓋骨髕骨骨折排序錯亂之疾病,然而由於傳統X光檢查常無法顯示正確的膝蓋病變導致早期診斷困難重重,只能仰賴於早期臨床症狀之警示,在病患經歷創傷之後呈現膝蓋血腫並主訴其膝蓋有異物滑動之特殊感覺,急診醫師就應高度懷疑是否為髕骨脫位不全合併髕骨軟骨骨折之可能性。我們提供這樣的病例經由臨床症狀分析討論確立診斷並做文獻回顧探討。

並列摘要


Patellar subluxation with osteochondral fracture due to acute trauma is uncommon in emergency medicine. Patients with peripatellar pain frequently have underlying patellofemoral malalignment. However, early diagnosis may be difficult because of the lack of association between the pathological changes that produce the consequence of the tracking abnormalities and traditional radiographic views. The diagnosis of patellofemoral malalignment and chondral damage is usually established through clinical findings. The condition should be suspected when there is hemarthrosis following trauma, and particularly where the patient describes any sort of disorientation or malalignment in the knee.Herein, we elucidate the clinical aspects of patellar subluxation with osteochondral fracture and review the relevant literature.
