[A retrospective study on risk factors associated with postoperative delirium in elderly patients with spinal operation].

Objective: To investigate the incidence and risk factors of delirium after spinal surgery in elderly patients.

Methods: A retrospective analysis was performed on 436 patients with spinal surgery from January 2016 to November 2018. According to delirium occurrancy after the operation, 436 cases were divided into two groups:delirium group and non-delirium group.

[Application of sacral rod fixation for the treatment of lumbosacral segment tuberculosis].

Objective: To evaluate the clinical outcomes of primary anterior radical debridement, bone autograft, and sacral rod fixation for the treatment of tuberculosis of the lumbosacral segment.

Methods: From March 2004 to November 2008,11 patients with tuberculosis of the lumbosacral segments received antituberculosis medications for 2 to 3 weeks before anterior radical debridement, autologous iliac bone grafting, and internal sacral rod fixation. Among the patients, 5 patients were male and 6 patients were female, with an average age of (44.

One-stage anterolateral surgical treatment for lumbosacral segment tuberculosis.

Purpose: The purpose of this study was to evaluate clinical outcomes following one-stage anterior radical debridement, interbody fusion, and sacral rod fixation for the treatment of lumbosacral segment tuberculosis.

Methods: From March 2004 to November 2008, 11 patients diagnosed with spinal tuberculosis received antituberculosis medications for two to three weeks before anterior radical debridement, autologous iliac bone grafting, and internal sacral rod fixation. Surgery was performed when the toxic symptoms of tuberculosis were controlled and erythrocyte sedimentation rates (ESR) decreased to 37.

Hemiarthroplasty vs primary total hip arthroplasty for displaced fractures of the femoral neck in the elderly: a meta-analysis.

Current updated meta-analysis was designed to compare clinical effects of hemiarthroplasty (HA) vs primary total hip arthroplasty (THA) for displaced femoral neck fractures in elderly patients. Five randomized and 4 quasi-randomized controlled trials with a total 1208 patients were included for final analysis. It showed that mortality and postoperative infection between HA and THA had no statistical differences, that long-term reoperation rate of HA was higher than that of THA, that medium-term dislocation rate of HA was lower than that of THA, and that pain rates of HA in short-term and long-term were both higher than THA.

Venous drainage in retrograde island flap: an experimental study using fluorescence tracing technique.

The pathway of venous drainage in retrograde island flaps was investigated by fluorescence tracing technique using the saphenous fasciocutaneous flap in New Zealand White rabbits. Forty animals were allocated into four groups according to the different times at 30 minutes (I), 24 hours (II), 72 hours (III), and 7 days (IV) after the operation. According to the different routes to give tracer, each group was further allocated into two subgroups of the artery injection and vein injection.
