To investigate the effect of rapid rehabilitation of percutaneous kyphoplasty/percutaneous vertebroplasty (PKP/PVP) in the treatment of senile thoracic and lumbar and sacral fractures with MRI combined with DR.

From January 2016 to December 2018 in department of orthopedics, Sihong County People's Hospital in Jiangsu Province, 69 patients with T5-S1 elderly thoracic and lumbar and sacral fractures were treated with MRI combined with DR imaging and digital PKP/PVP. Pain scores were performed by visual analogue score method. X-ray films were used to measure the ratio of anterior and posterior vertebral heights and cobb angles before and after surgery. Statistical analysis was performed to evaluate the efficacy.

69 patients were followed up for 3 to 24 months with an average of 18±11 months. The intraoperative blood loss was 2-15 ml, with an average of 5.0±2.1 ml. The operation time was 30-120 min with an average of 55±7 min. There was no spinal nerve injury during operation, 1 case of old fractures had asymptomatic intervertebral space artificial bone leakage, 2 cases of PMMA paraspinal leakage. The pain VAS score returned from preoperative 7.5±0.7 points to 0.7±0.7 points one month after operation. The anterior-posterior height ratio of the vertebral body recovered from 62±32 before surgery to 94±38 one month after operation. Cobb’s angle recovered from preoperative 16±5° to 2.6±1.4° one month after operation. The differences were statistically significant (P<0.01).

MRI combined with DR film positioning digital PKP/PVP rapid rehabilitation treatment of elderly thoracic and lumbar and sacral fractures, can reduce the risk of bone cement leakage, correct kyphosis deformity, obtain early rapid rehabilitation, good fracture healing.
