Sciatica is a common problem, usually caused by disc herniation or spinal stenosis. Low back pain is also present in most cases. When sciatica is the unique clinical finding, especially in young patients, extraspinal pathology should be investigated.
We describe a rare case of sciatica in a 32-year-old man, which was developed as a complication of post-traumatic pelvic heterotopic ossification. During the operation, the sciatic nerve was found to be bluish, distorted and compressed in an hourglass fashion around a heterotopic bone mass. The heterotopic bone tissue, 4 cm in diameter, was removed and the patient had fully recovered 3 months after the operation.
In cases of sciatica without back pain, the possibility of direct pressure of the sciatic nerve from cysts, tumours or bone, as in the present case, should be considered.
坐骨神经痛是一种常见问题，通常由椎间盘突出或椎管狭窄引起。大多数情况下也会出现腰痛。当坐骨神经痛是唯一的临床发现时，尤其是在年轻患者中，应调查脊柱外病变。
我们描述了一名32岁男性的罕见坐骨神经痛病例，该病例是创伤后骨盆异位骨化的并发症。手术中发现坐骨神经呈蓝色，扭曲并在异位骨块周围呈沙漏状受压。切除了直径4厘米的异位骨组织，患者术后3个月完全康复。
在无腰痛的坐骨神经痛病例中，应考虑如本病例中坐骨神经受到囊肿、肿瘤或骨骼直接压迫的可能性。
