S rod fixation to the sacrum in patients with neuromuscular spinal deformities.
A new form of pelvic fixation has been designed for use in patients with neuromuscular spinal deformities to overcome the problems imposed by the Galveston technique. One end of a Luque rod is prebent into an S shaped configuration and placed over the sacral ala supplying firm fixation across the lumbosacral junction without crossing the sacroiliac joint. It fixes firmly against the sacral ala by distracting against a hook or screw in the lumbar spine. A 12 year retrospective review of 67 patients with severe neuromuscular spinal deformities was accomplished. All surgeries were performed by one surgeon. All patients had good deformity correction with an average followup of 6 years and 2 months. Complications included: recurrence of pelvic obliquity (one patient), skin break-down over hardware (one patient), migration of hardware at sacrum (two patients), and rod breakage (five patients). The S rod is recommended for all patients with neuromuscular spinal deformities who require instrument fixation to the pelvis. Its ease of insertion and decreased operative time allow for a safe and dependable alternative fixation to the sacrum without crossing the sacroiliac joint.
