Abstract:

BACKGROUND: Fabric pod is a novel device for preventing cement leakage, which applied in kyphoplasty can obtain satisfactory outcomes and effectively avoid cement leakage. However, the clinical efficacy of orthosis worn after fabric pod kyphoplasty remains controversial.

OBJECTIVE: To assess the effect of thoracolumbar orthosis on osteoporotic compression fracture patients after fabric pod kyphoplasty.
METHODS: Thirty patients (42 vertebrae) with osteoporotic vertebral compression fracture without neurologic injury undergoing fabric pod kyphoplasty were enrolled. The patients were randomized into wearing orthosis group (n=15, 22 vertebrae)) and control group (n=15, 20 vertebrae, without orthosis) after surgery. During the follow-up, the moving ability returned to preinjury level, Visual Analogue Scale scores, radiographic results and Activities of Daily Living scores were evaluated and compared. All patients were followed up for 3-18 months.
RESULTS AND CONCLUSION: (1) All patients in both groups got significant pain relief after surgery. (2) The postoperative Visual Analogue Scale and Activities of Daily Living scores at postoperative 24 hours were significantly improved in both groups compared with the baseline (P < 0.05). In the control group, there was significant difference in the Visual Analogue Scale scores at the last follow-up compared with the 24 hours (P < 0.05). In the wearing orthosis group, the Visual Analogue Scale scores at the last follow-up showed no significant difference from the 24 hours (P > 0.05), indicating the good efficacy in the wearing orthosis group. (3) The height of injured vertebrae and Cobb angle in both groups at postoperative 24 hours and last follow-up showed significant difference compared with the baseline (P < 0.05), but there was no significant difference between postoperative 24 hours and last follow-up (P > 0.05). (4) The moving ability returned to preinjury level showed significant difference between wearing orthosis group (7.0±2.8) days, and control group (14.0±4.8) days (P < 0.05). (5) During the follow- up, no adjacent vertebral compression fracture or pain recurrence occurred in the wearing orthosis group. In the control group, four patients had pain recurrence and adjacent vertebral compression fracture. (6) These results suggest that fabric pod kyphoplasty is an effective treatment to relieve pain, improve the vertebral height and ensure satisfactory short-term results. Wearing orthosis after surgery can promote the recovery, shorten the hospitalization time and obtain satisfactory clinical outcome.
