Treating Osteoporotic Spinal Fractures in Elderly Patients via a Modified Clinical Bone Cement Injection Technique

Summary

Presented here is a modified procedure for minimally invasive injections of bone cement to treat osteoporotic spinal fractures in elderly patients.

Abstract

The minimally invasive injection of bone cement (MIIBC) is an effective way to treat senile osteoporotic spinal fractures (OSF) in clinical practice. However, the intraspinal dura and nerves may be damaged when the puncture needle passes through the pedicle. Therefore, in this protocol, the puncture site was optimized during the surgery, selecting the same 1-2 cm away from the surface projection of the diseased vertebra. The needle was punctured along the lateral cortex of the pedicle from the junction of the pedicle and the vertebral body into the vertebral body. Meanwhile, bone cement was used as a filling material, and the MIIBC was performed by a percutaneous puncture at the external edge of the pedicle under C-arm fluoroscopy. This modified puncture site is far away from the spinal canal as possible, thereby reducing the risk of the puncture needles penetrating the spinal canal and damaging the nerves and dura mater. In conclusion, a modified MIIBC by percutaneous lateral pedicle puncture can effectively relieve pain in elderly patients with OSF.

Introduction

Osteoporosis is a common disease among middle-aged and elderly women. Statistics show that about 54% of postmenopausal women have abnormal bone density, and the chance of vertebral fracture over the age of 50 is about 32%¹. Osteoporotic spinal fractures (OSF) occur most commonly in women and are mainly compression fractures caused by direct or indirect external forces^1,2. After the fracture, the sagittal balance of the spine is broken, resulting in vertebral deformation, diffuse lumbar and back pain, and kyphosis². In addition, some patients also experience abdom....

Protocol

The surgical operation using MIIBC for the treatment of an osteoporotic fracture of the seventh thoracic vertebra in a 68-year-old woman was approved by the Ethics Committee of Linfen People's Hospital of Shanxi Medical University (T20220829006). The patient provided written informed consent.

Discussion

Traditional open internal fixation is used with patients who have the neurological symptoms of a vertebral compression fracture and a fractured mass entering the spinal canal and pressing on the spinal cord and nerve roots¹⁵. This technique is especially suitable for individuals with severe violent vertebral trauma, such as from a car accident or falling from height. This kind of emergency surgery usually requires spinal canal decompression, which has a long operation time and a large area of trau.......
