See the published version at [https://doi.org/10.1186/s13018-023-04189-3](https://doi.org/10.1186/s13018-023-04189-3) .  \nPage 1/14  \nThe risk of Osteoporotic Vertebral Collapse(OVC) associated with delayed neurological dysfunction(DND) is high, and surgery for it in the elderly is challenging. How to simplify surgical procedures while preserving surgical e¨cacy has become a hot topic in treatment. This study aims to provide clinical data to support the advancement of modi¦ed posterior osteotomy for the treatment of thoracolumbar OVC with DND by comparing perioperative clinical parameters, imaging data characteristics and changes in e¨cacy outcome indicators.  \n 12 patients were diagnosed for Osteoporotic Vertebral Collapse in combination with neurological dysfunction. Modi¦ed Posterior osteotomy in all patients were designed. The perioperative, and radiological parameters and complications, including surgery duration, blood loss, ASIA grade,VAS, ODI, Regional Kyphosis Angle(RKA), Anterior Vertebral Height ratio(AVHr), Spinal Canal Invasion ratio(SCIr) , were collected retrospectively and analyzed to evaluate the clinical e¨cacy and safety of this technique.  \n Of the12 patients, Mean age: 65. 50 ± 9 .70 years, mean follow-up: 29.42 ± 4 .98 months, mean operative blood loss: 483.33 ± 141.96 ml, mean operative time: 3.71 ± 0 .66 hours, VAS score decreased from preoperative 5.83 ± 0 .72 to ¦nal follow-up 1.25 ± 0 .75 (P\u003C0.05) . Postoperative ODI reduced to 31.46%, and postoperative neurological function was signi¦cantly improved. The RKA was corrected from  \n35.8±10 .83° to 20.03±3 .54° after surgery and to 22.47±3 .08° at ¦nal follow-up; AVHr% was corrected from 39.32±18 .02 to 63.03±14 .29 after surgery and to 53.89±8 .94 at ¦nal follow-up; SCIr% was corrected from 54.88±5 .41 to 68. 13±5 .30 after surgery and to 68.68±6 .76 at ¦nal follow-up; Spinal canal volume immediately following surgery was increased by 24. 14% .  \n Posterior modi¦ed osteotomy is an effective treatment for thoracolumbar osteoporotic fractures with OVC combined with DND. It can signi¦cantly preserve vertebral height, increase vertebral canal volume, correct kyphotic angle, and improve postoperative neurological function. The simpli¦ed osteotomy also has certain advantages in terms of operating time, blood loss, postoperative VAS score and improvement in lumbar function.  \nAs the world's population ages, the incidence of osteoporotic fractures continues to increase. Currently, the literature reports that the number of 50-year-old Americans with osteoporosis is nearly 54 million, of which 2 million have osteoporotic vertebral compression fracture (OVCF),most of which occur in the thoracolumbar region (T11, T12, L1 and L2) [1].  \nFor osteoporotic vertebral compression fracture, traditional conservative treatment can result in bone healing, reduced pain and mild kyphosis. However, if conservative treatment fails, progressive Osteoporotic Vertebral Collapse (OVC) may occur) [2]. Taneichi et al[3] reported that 13. 5% of patients with OVCF experience pseudarthrosis, and about 3% of OVC patients may experience secondary nerve damage due to bone block displacement and spinal stenosis. Osteoporosis itself can impede the healing of vertebral fractures, while the progressive loss of vertebral height and increasing kyphosis accelerate","cbCaieMsdh7nammx","https://ap.wps.com/l/cbCaieMsdh7nammx","pdf",4260626,14,"English","# Background\n# Study Design and Methods\n## Patients and Surgical Technique\n## Outcomes and Data Collection\n# Results\n# Conclusion","[{\"question\":\"What clinical problem does the study address in elderly patients?\",\"answer\":\"The study targets osteoporotic vertebral collapse (OVC) associated with delayed neurological dysfunction (DND), where surgical treatment is considered challenging.\"},{\"question\":\"What method did the researchers evaluate for thoracolumbar OVC with DND?\",\"answer\":\"All 12 patients underwent a modified posterior osteotomy, and perioperative plus radiological parameters were retrospectively analyzed.\"},{\"question\":\"Which outcomes were used to judge efficacy and safety?\",\"answer\":\"Outcomes included surgery duration, blood loss, ASIA grade, VAS pain score, ODI, regional kyphosis angle (RKA), anterior vertebral height ratio (AVHr), spinal canal invasion ratio (SCIr), and changes in spinal canal volume.\"}]","Osteoporotic Vertebral Collapse with Delayed Neurological Dysfunction - Modified Posterior Osteotomy | PDF",1791265686,35]
