Patellar sleeve fracture is a rare fracture common in children between the age of 8 and 16 years but rare in adults. We report a case of 22 year old male with inferior patellar sleeve fracture following motorbike accident.
The case study presents a twenty-two year old boy who sustained inferior patellar Sleeve fractures following motor bike accident. The patient presented to ER with pain and swelling along with abrasion. Diagnostic workup, including blood test and imaging, confirmed the diagnosis, revealing elevated inflammatory markers and evidence of inferior patellar sleeve fracture on X-ray. The fracture was managed by Open reduction and internal fixation with ortho cord suture.
Sleeve fractures of the patella in children usually occur in the inferior pole of the patella, very rarely in the superior pole. However, sleeve fractures of the patella mainly affect the superior pole in adults. The mechanism of sleeve fracture is a rapid contraction of the quadriceps on a flexed knee. Sleeve fractures usually occur in individuals involved in explosive acceleration activities such as jumping, although high-energy sports such as skateboarding are now also considered common causes Clinically, treatment options including conservative and surgical treatment depends on the severity of bone displacement and the extensor mechanism of the knee.
Inferior patellar sleeve fracture is rare in adults in comparison to the children. The fracture is confirmed through X-rays AP and Lateral view. Thus, diagnosed fracture is treated surgically via open reduction and internal fixation.
髌骨套状骨折是一种罕见的骨折，常见于8至16岁的儿童，但在成人中罕见。我们报告一例22岁男性在摩托车事故后发生髌骨下极套状骨折的病例。
该病例研究的是一名22岁男孩，他在摩托车事故后发生了髌骨下极套状骨折。患者因疼痛、肿胀及擦伤就诊于急诊科。包括血液检查和影像学检查在内的诊断性检查确诊了病情，显示炎症标志物升高，X线片显示有髌骨下极套状骨折的迹象。该骨折通过切开复位并用矫形缝线内固定进行治疗。
儿童髌骨套状骨折通常发生在髌骨下极，极少发生在上极。然而，成人髌骨套状骨折主要影响上极。套状骨折的机制是膝关节屈曲时股四头肌的快速收缩。套状骨折通常发生在参与爆发性加速活动（如跳跃）的个体中，尽管现在像滑板运动这样的高能运动也被认为是常见原因。临床上，治疗选择包括保守治疗和手术治疗，这取决于骨移位的严重程度和膝关节的伸肌机制。
与儿童相比，成人髌骨下极套状骨折罕见。通过X线前后位和侧位片确诊骨折。因此，确诊的骨折通过切开复位和内固定进行手术治疗。
