AI Article Synopsis
- Vertebral compression fractures (VCF) often occur at the thoracolumbar junction (TLJ), and balloon kyphoplasty (BKP) is an effective treatment for bone remodeling in these cases.* -
- A study involving 31 patients evaluated how factors like timing of surgery, age, sex, and body mass index (BMI) affect outcomes such as vertebral height and spinal angles after BKP.* -
- Results show that early surgery leads to better recovery in vertebral heights, older patients experience more significant angle reduction, and those with a higher BMI have lower local kyphotic angles post-surgery.*
Article Abstract
Aim: Vertebral compression fractures (VCF) occur most commonly at the thoracolumbar junction (TLJ). Balloon kyphoplasty (BKP) is an effective method of bone remodeling in these cases. In this study, we evaluate the parameters that affect bone retropulsion and restoration in TLJ VCF without neurological deficits.
Material And Methods: Thirty-one of Frankel E and AO A3-4 type VCFs fractures at the TLJ, with bone retropulsion into the spinal canal, from 2017 to 2020, were evaluated retrospectively. Data was gathered on patient demographics and medical histories. Measurements of anterior vertebral heights, posterior vertebral heights, local kyphotic angles, spinal cord area, and bone retropulsion into the spinal canal (BRC) were evaluated preoperatively, early postoperatively, and late postoperatively.
Results: In those patients who underwent early surgery ( 4 weeks postfracture), a significantly greater increase in anterior vertebral heights was seen between early postoperative and preoperative measurements than in patients who underwent late surgery ( 4 weeks postfracture) (p = 0.016). At the six-month follow-up, a significantly greater decrease in local kyphotic angle measurements was seen in patients over 65 years of age than those under 65 (p = 0.023). Comparison of local kyphotic angles between sexes revealed a significant decrease in measurements at follow-up in female patients (p = 0.029). Both early postoperative and late postoperative local kyphotic angle measurements of patients with a body mass index (BMI) ≥25 were significantly lower than those of patients with a BMI 25 (p = 0.012).
Conclusion: The restoration of vertebral angles and heights with the maximum level of BKP can effectively reduce BRC.

Validity and reliability of the osteoporotic fracture treatment score (OF score) and outcomes across various treatments in osteoporosis vertebral compression fracture patients.
J Orthop Surg Res

Department of Orthopaedic Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
Background: Osteoporotic vertebral compression fractures (OVF) are prevalent and substantially impact healthcare systems and patients' quality of life. The osteoporotic fracture treatment score (OF score), developed by the German Society of Orthopedics and Trauma (DGOU), guides surgical decisions, but its reliability and validity are underexplored. This study assessed the OF score's inter- and intraobserver reliability, validated its treatment recommendations, and investigated intermediate outcomes of different DGOU-recommended surgical strategies for OVF.

Article Synopsis
- The study explores the effectiveness of two surgical methods for treating Andersson lesions (AL) in patients, comparing minimally invasive spinal surgery (MIS) to open spinal fusion (OSF) to assess clinical outcomes and recovery.
- A total of 30 patients were analyzed, with no significant differences in pain or disability scores after surgery between the MIS and OSF groups, although both methods showed improvement in these areas.
- Key findings indicate that both surgical techniques were successful with no complications, highlighting the potential for MIS to be a viable alternative to the more traditional OSF approach.
Clinical Outcome of Posterior Instrumented Stabilization and Transpedicular Decompression in Patients Presenting with Thoracic or Lumbar Spinal Tuberculosis in a Tertiary Care Center: A Descriptive Cross-sectional Study.

Introduction: Posterior instrumented stabilization is a commonly done surgery in spinal tuberculosis. This study aims to evaluate the clinical, radiological, and neurological outcomes of posterior instrumented stabilization and transpedicular decompression in thoracic and lumbar spinal tuberculosis.
Methods: A descriptive cross-sectional study was conducted for one and a half years with at least six months of follow-up in a tertiary care center.
Lateral Sacral Artery Perforator Flap as a New Option in Myelomeningocele Reconstruction.

Department of Neurosurgery, University of Medical Science, Sisli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey.
Article Synopsis
- The study investigates the use of lateral sacral artery perforator (LSAP) flaps for reconstructing myelomeningocele, highlighting their potential as a new surgical option.
- Eleven patients underwent the procedure, with a total of 22 LSAP flaps used; results showed an average operation time of 57 minutes and minimal complications.
- The authors suggest LSAP flaps could be beneficial for lumbar region defects and recommend them as a viable alternative for reconstructing pressure sores in the kyphotic region.
Early Balloon Kyphoplasty Treatment for Osteoporotic Vertebral Fracture Reduces Adjacent Vertebral Fractures.

: This study retrospectively examined whether the incidence rates of adjacent vertebral fractures (AVFs) can be reduced through balloon kyphoplasty (BKP) for osteoporotic vertebral fractures (OVFs) in the early stages, when there is little vertebral height variation. : A total of 95 patients (22 males, 73 females, mean age: 80.7 years) who had undergone BKP were divided into two groups: the Early group (underwent BKP within 2 weeks after injury, = 62), and the Non-early group (underwent BKP > 2 weeks after injury, = 33).
