Abstract
Background: The management goal of spinal disorders with deformity is to safely realign the spine and decompress the neurological elements. However, many limitations are associated with standard osteotomy techniques used for managing these deformities.
Purpose: We reported posterior vertebral column resection technique, including resection of at least one whole vertebra with the cephalic and caudal disc, accompanied by posterior instrumentation with pedicle screws, with the aim to decrease surgical related complications.
Methodology: from April 2014 till April 2016, 35 patients (17 males/18 females) with rigid spinal deformities at our institution underwent PVCR of those 19 were kyphosis cases and 16 were kyphoscoliosis. The diagnoses included 22 congenital, 5 post traumatic, 4 post infectious and 4 neuromuscular cases. Preoperative and postoperative radiographic evaluation was performed. Intraoperative and postoperative complications were noted.
Results: For kyphosis cases an average of 1.57 vertebrae was resected (range, 1–3 vertebrae). The mean preoperative kyphosis was 68.9° (range, 20°-130°), and the mean kyphosis postoperatively was 24.5° (range, 5°-55°) with an average postoperative correction of 45°. For kyphoscoliosis cases an average of 1.5 vertebrae was resected, the correction rate was 75% in the coronal plane from a mean of 38° preoperatively to a mean of 11°. Sagittaly, the average preoperative curve of 70° was corrected to 22.5°. All patients had solid fusion at latest follow-up. Complications were encountered in seven patients, including dural tear (n = 2), pleural tear (n = 2), Wound infection (n = 2), PJK + Implant failure (n = 3), Implant failure and wound infection (n = 1).
Conclusion: The results of this study show that single stage posterior VCR is a highly effective option in management of complex spinal disorders.
