Does intrawound vancomycin powder reduce surgical site infection after posterior instrumented spinal surgery? A propensity score-matched analysis.

Background Context: Recent reports suggested that placing vancomycin powder into surgical wounds before closure can prevent surgical site infections (SSIs) in spinal surgery.

Purpose: The present study aimed to evaluate if intrawound vancomycin powder could prevent SSIs after spinal surgery with posterior instrumentation.

Study Design: This is a multicenter retrospective cohort study using propensity score matching.

Psychometric Assessment of the Japanese Version of the Zurich Claudication Questionnaire (ZCQ): Reliability and Validity.

Purpose: The Zurich Claudication Questionnaire (ZCQ) is a self-administered measure to evaluate symptom severity, physical function, and surgery satisfaction in lumbar spinal stenosis (LSS). The purpose of this study is to assess the psychometric properties of the Japanese ZCQ in LSS patients.

Methods: LSS patients who are scheduled to undergo surgery were recruited from 12 facilities.

Prospective multicenter surveillance and risk factor analysis of deep surgical site infection after posterior thoracic and/or lumbar spinal surgery in adults.

Background: Surgical site infection is a serious and significant complication after spinal surgery and is associated with high morbidity rates, high healthcare costs and poor patient outcomes. Accurate identification of risk factors is essential for developing strategies to prevent devastating infections. The purpose of this study was to identify independent risk factors for surgical site infection among posterior thoracic and/or lumbar spinal surgery in adult patients using a prospective multicenter surveillance research method.

Long-term follow-up of the progression of ossification of the posterior longitudinal ligament.

The authors report the case of a man with cervical ossification of the posterior longitudinal ligament (OPLL) who was observed for more than 26 years. Initial symptoms consisted of subtle numbness of the hands, and initial radiography showed small, segmental-type OPLL in the cervical spine. Lateral radiography of the cervical spine was performed every few years.

Predictors of residual symptoms in lower extremities after decompression surgery on lumbar spinal stenosis.

Leg pain/numbness and gait disturbance, two major symptoms in the lower extremities of lumbar spinal stenosis (LSS), are generally expected to be alleviated by decompression surgery. However, the paucity of information available to patients before surgery about specific predictors has resulted in some of them being dissatisfied with the surgical outcome when the major symptoms remain after the procedure. This prospective, observational study sought to identify the predictors of the outcome of a decompression surgery: modified fenestration with restorative spinoplasty.

Correction of scoliosis using segmental pedicle screw instrumentation versus hybrid constructs with hooks and screws.

Eighteen consecutive patients with scoliosis surgically treated by posterior correction and fusion were recruited. The major coronal curve averaged 65.8 degrees (range 51 degrees -87 degrees ).

Validity and reliability of SRSI and SF-36 in Japanese patients with scoliosis.

We have examined the validity and reliability of Japanese SRS-24 and SF-36 in patients with scoliosis. 278 patients with scoliosis were recruited. Their average age was 24.
