OBJECTIVE: Sacroiliac joint ache might be disabling and recalcitrant to medical remedy. The innervation of this joint is poorly understood, particularly its anterior facet. Due to this fact, the current cadaveric examine was carried out to raised elucidate this anatomy.
METHODS: Twenty-four cadaveric sides underwent dissection of the anterior sacroiliac joint, with particular consideration given to any branches from regional nerves to this joint.
RESULTS: No femoral, obturator, or lumbosacral trunk branches destined to the anterior sacroiliac joint had been recognized within the 24 sides. In 20 sides, one or two small branches (lower than zero.5 mm in diameter) had been discovered to come up from the L4 ventral ramus (10%), the L5 ventral ramus (80%), or concurrently from each the L4 and L5 ventral rami (10%). The size of the branches ranged from 5 to 31 mm (imply, 14 mm). All these branches arose from the posterior a part of the nerves and traveled to the anterior floor of the sacroiliac joint. No statistical significance was discovered between sides or sexes.
CONCLUSIONS: An improved information of the innervation of the anterior sacroiliac joint would possibly lower struggling in sufferers with continual sacroiliac joint ache.
