Abstract: BACKGROUND: Stage III Kümmell’s disease is characterized by a high degree of vertebral compression and posterior wall defects. Most of the patients are elderly people with severe osteoporosis and various medical diseases. Clinically, some surgical methods are often at high risk and are controversial.  
OBJECTIVE: To investigate the clinical efficacy of screw placement combined with transpedicular impaction bone grafting in the treatment of stage III Kümmell’s disease. 
METHODS: The clinical data of injured vertebral screw placement combined with transpedicular impaction bone grafting in treatment of stage III Kummell’s disease from May 2016 to August 2021 were retrospectively analyzed. Visual analog scale score, Oswestry disability index, anterior vertebral heights, kyphotic Cobb angle and American Spinal Injury Association (ASIA) impairment scale were used to evaluate the effects of surgery. The operation time, intraoperative blood loss and complications were recorded. CT scans were used to evaluate the healing of injured vertebrae at the final follow-up visit. 
RESULTS AND CONCLUSION: (1) A total of 26 patients were included, with 7 males and 19 females, at the age range of 62-81 years [mean (69.7±4.8) years]. The follow-up time was 18-60 months [mean (35.1±8.9) months]. The average operative duration was 133.5 minutes (100-165 minutes), and the average intraoperative blood loss was 285.3 mL (210-350 mL). (2) Visual analog scale and Oswestry disability index scores 1 week after surgery were significantly lower than those before surgery. (3) At 1 week after surgery, the anterior vertebral height corrections and the Cobb angle were (9.0±0.7) mm and (16.2±1.0)°, respectively. During the follow-up period, the loss of vertebral height and kyphosis correction were (5.1±0.3) mm and (8.0±0.4)°, respectively. (4) 14 patients (54%) had ASIA grade D before operation, which recovered to grade E at the last follow-up. CT scan showed that all patients achieved good osseous union. (5) Complications occurred in seven patients (27%), including hypostatic pneumonia in two cases, postoperative superficial wound tissue liquefaction in two cases, and adjacent vertebral compression fractures in three cases. (6) It is concluded that screw placement of the injured vertebra combined with transpedicular impaction bone grafting can rapidly rebuild spinal stability, effectively relieve pain and improve neurological function in the treatment of stage III Kümmell’s disease. This technique is an effective and relatively minimally invasive surgical option.
