Clinical Anatomy of the Sacral Nerve Roots and Its Relevance to Their Reconstruction After Sacrectomy
Original language description
BACKGROUND AND OBJECTIVES: En bloc sacrectomy is associated with sacral root transection causing loss of urinary bladder, rectum, and sexual function. The aim of the study was to determine the position of the pudendal branches (sensorimotor) and pelvic splanchnic nerves (parasympathetic) on the sacral roots relative to the sacrum, and the minimal and maximal defects in the sacral roots that can be reconstructed by grafting after various types of sacrectomy. METHODS: Five cadaveric pelves were dissected bilaterally. The lengths and widths of the S1-S4 roots and their branches were measured. Then, the minimal and maximal defects between the proximal and distal stumps of the sacrificed roots were measured following 3 models of sacrectomy (below S2, below S1, and total sacrectomy). RESULTS: The mean distance of the splanchnic nerves from the S2 and S3 anterior sacral foramina was 17.7 +- 7.3 and 23.6 +- 11.1 mm, respectively, and the mean distance of the pudendal S2 and S3 branches was 36.8 +- 13.7 and 30.2 +- 10.8 mm, respectively. The mean widths of the S2 and S3 roots were 9.3 +- 1.9 and 5.4 +- 1.2 mm, respectively. The mean maximal defects in S2 and S3 roots after various types of sacrectomies were between 61.8 +- 16.3 and 100.7 +- 14.3 mm and between 62.7 +- 20.2 and 84.7 +- 25.1 mm, respectively. There were no statistically significant differences between sides or sexes for all obtained measurements. CONCLUSION: The reconstruction of the S2-S3 roots is anatomically feasible after partial or total sacrectomies in which the resection of the soft tissue does not extend further than approximately 1.5 to 2 cm ventrally from the sacrum.
