Hollow Screw Placement Combined with Percutaneous Vertebroplasty Serves as a Valuable Three-Column Intensive Treatment for Patients with Kummell's Disease and Pedicle Rupture.

Purpose: To introduce the surgical methods and clinical results of percutaneous vertebroplasty (PVP) combined with hollow screw placement as a treatment for patients with Kummell's disease and pedicle rupture.

Methods: From January 2020 to January 2023, a total of 10 patients with Kummell's disease and pedicle rupture confirmed via imaging underwent three-column intensive therapy using hollow screws combined with PVP. There were two males and eight females with an average age 75.

Treatment of thoracolumbar fractures by temporary posterior instrumentation with selective fusion schemes.

Objective: This retrospective study investigated the clinical and radiographic outcomes following temporary transpedicular posterior instrumentation between two cohorts of patients with thoracolumbar fractures (TLF) who underwent selective or bi-segments intervertebral articular process fusion.

Methods: Patients with TLF who underwent the temporary posterior fixation with selective fusion (Group SF), or bi-segments fusion (Group BF) were studied. Superior intervertebral articular process and interlaminar fusion were performed in Group SF, whereas in Group BF, the patients underwent bi-segments fusion in both superior and inferior articular processes, as well as interlaminar fusion.

Infection Risk of Lumbar Epidural Injection in the Operating Theatre Prior to Lumbar Fusion Surgery.

Purpose: To determine the association between preoperative lumbar epidural injections (LEIs) in the operating theater (OR) and the occurrence of surgical site infection (SSI) after posterior lumbar instrumented fusion surgery.

Methods: This study was performed from January 2015 to September 2019. We enrolled 2312 patients who underwent lumbar surgery without LEIs (control group) and 469 patients who underwent lumbar surgery after LEIs in the OR.
