The patellar fractures are common in adults, but rare in children. As a particular type of patellar fracture, however, sleeve fractures are almost always limited to children in the under 16's group.
Herein, we report a rare case of a 19-year-old healthy adult female who presented sleeve fracture at the superior pole of the left patella. The clinical and radiological features are found including joint effusion, anterior tilt of the patella and a shell of bone lying proximally to the patella.
Computed tomography and magnetic resonance imaging examination have been performed to further confirm the diagnosis of sleeve fracture, rupture of the quadriceps tendon and the cartilaginous injury.
Under general anaesthesia, she underwent open surgical procedures for reconstituting anatomically the fracture and repairing the rupture of the quadriceps tendon.
Six months after the operation, she could fully use her left knee without any pain and disability.
Sleeve fractures of the patellar in adults are extremely rare, and our case is of interest for the first time occurring in healthy female adults. Our case report and literature review was aim to describe the clinic and imaging characteristics of superior pole sleeve fractures in adults, and highlight that physicians must be aware of this entity in adults so as to reduce misdiagnosis due to unfamiliarity.
髌骨骨折在成年人中较为常见，但在儿童中罕见。然而，作为一种特殊类型的髌骨骨折，袖套状骨折几乎仅见于16岁以下儿童。
在此，我们报告一例罕见病例，一名19岁健康成年女性，左髌骨上极出现袖套状骨折。发现其临床和影像学特征包括关节积液、髌骨前倾以及位于髌骨近端的骨壳。
已进行计算机断层扫描和磁共振成像检查，以进一步确诊袖套状骨折、股四头肌肌腱断裂和软骨损伤。
在全身麻醉下，她接受了开放手术，以解剖复位骨折并修复股四头肌肌腱断裂。
术后六个月，她能够完全使用左膝，无任何疼痛和功能障碍。
成人髌骨袖套状骨折极为罕见，我们的病例首次发生在健康成年女性中，具有一定意义。我们的病例报告和文献综述旨在描述成人髌骨上极袖套状骨折的临床和影像学特征，并强调医生必须了解成人中的这种情况，以减少因不熟悉而导致的误诊。
