Analysis of cervical sagittal alignment variations after lumbar pedicle subtraction osteotomy for severe imbalance: study of 59 cases.

Objective: To evaluate postoperative changes within the cervical alignment following surgical lumbar correction by pedicle subtraction osteotomy (PSO) in patients affected with sagittal global malalignment disease.

Methods: This was a monocentric, radiographic, and prospective study. 79 patients, who underwent sagittal correction by PSO, performed an EOS imaging pre- and postoperatively between January 2008 and December 2013 at the University Hospital of Bordeaux.

Comparison between percutaneous and traditional fixation of lumbar spine fracture: intraoperative radiation exposure levels and outcomes.

Objective: To compare radiation exposure doses and clinical and radiological outcomes between percutaneous pedicular screwing (closed reduction internal fixation [CRIF]) and classical open reduction internal fixation (ORIF) in lumbar spine fracture without neurologic deficit.

Materials And Methods: Sixty patients (mean age, 42.5 years) were divided into two treatment groups: (Percutaneous) CRIF versus (traditional) ORIF.
