Thirty-seven dissections have shown that the skin of the low back is innervated by the lateral branches of the dorsal rami of T12 and LI in 22 cases (60%) or T12 L1 and L2, in 10 cases (27%) or T12 L1 and L2 receiving an anastomosis from L3 in 5 cases (13%). The most medial nerve crossed the iliac crest through a rigid osseo-aponeurotic orifice located 7-8 cm from the midline which was seen compressing the nerve in 2 instances. This pattern of distribution may sometimes explain unilateral low back pain.
37例解剖显示，22例（60%）下背部皮肤由T12和L1背侧支的外侧分支支配，10例（27%）由T12、L1和L2支配，5例（13%）由T12、L1和L2支配且L3有吻合支。最内侧的神经通过一个距中线7 - 8厘米的坚硬骨 - 腱膜孔穿过髂嵴，在2例中可见该孔压迫神经。这种分布模式有时可能解释单侧下背痛。
