Efficacy of Antibiotics Sprayed into Surgical Site for Prevention of the Contamination in the Spinal Surgery.

STUDY DESIGN: Retrospective study. PURPOSE: To evaluate the effect of intraoperative wound application of vancomycin on preventing surgical wound contamination during instrumented lumbar spinal surgery. OVERVIEW OF LITERATURE: Postoperative infection is the one of the most devastating complications of lumbar surgery. There are a few reports showing the benefits of intraoperative wound application of vancomycin during spinal surgery. However, there is no report about the effectiveness of local vancomycin instillation in prevention of surgical wound contamination. METHODS: Eighty-six patients underwent instrumented lumbar spinal surgery. Mean patient age was 65.19 years (range, 23-83 years). There were 67 females and 19 males. During surgery, vancomycin powder was applied into the surgical site before closure in 43 patients (antibiotic group) and vancomycin powder was not applied into the surgical site before closure in 43 patients (control group). The tip of the surgical drain was cultured to evaluate surgical wound contamination. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured on the first, third, seventh, and fourteenth day after the operation. RESULTS: We found two patients with a positive culture from the tip of surgical drains in the antibiotic group, and one patient with a positive culture from the tip of the surgical drain in the control group. Postoperative ESR and CRP levels did not show significant differences between the two groups. On the third postoperative day, ESR in patients of the antibiotic group was more significantly decreased than that in patients of the control group, while CRP level did not show a significant difference between the two groups. CONCLUSIONS: There was no evidence to suggest that intraoperative vancomycin application is effective in decreasing the risk of postoperative wound infection after instrumented posterior lumbar fusion surgery.

Factors influencing functional outcomes in united intertrochanteric hip fractures: a negative effect of lag screw sliding.

The purpose of this study was to investigate the factors influencing functional outcomes in elderly patients with united intertrochanteric fractures treated with hip nails and to ascertain whether decreased femoral offset due to lag screw sliding has a negative effect on functional outcomes in these patients. This retrospective study included 65 patients older than 65 years with united intertrochanteric fractures treated with hip nails. Functional outcomes were assessed using the Short Form-36 (SF-36) and a visual analog scale (VAS) 6 months postoperatively. Mean patient age was 77.8 years (range, 65-90 years); mean follow-up was 20.7 months (range, 12-38 months). More lag screw sliding occurred as bone mineral density (BMD) decreased. It was also greater in unstable fractures and acceptable reduction status. Less accurate reduction and greater lag screw sliding showed significant negative effects on most subscales of the SF-36, especially Physical Functioning and Role Physical. A significant positive correlation was observed between the extent of lag screw sliding and VAS. Lag screw sliding affected by fracture type, reduction quality, and BMD has a negative effect on functional outcomes in elderly patients with united intertrochanteric fractures. Therefore, the preservation of anatomical femoral offset as much as possible is needed to obtain better functional outcome through the minimization of lag screw sliding by more accurate reduction, which is a controllable factor, especially in osteoporotic unstable intertrochanteric fractures.

The Fascial Elevation and Tendon Origin Resection Technique for the Treatment of Chronic Recalcitrant Medial Epicondylitis.

BACKGROUND: Medial epicondylitis is a tendinopathy of the common flexor-pronator origin, and surgical treatment is required when this condition fails to respond to nonoperative methods. This study details the development of a new technique, termed fascial elevation and tendon origin resection (FETOR), which facilitates the complete visualization and resection of the CFPO with limited soft tissue dissection. PURPOSE: To evaluate the outcomes of FETOR for the treatment of chronic recalcitrant medial epicondylitis. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The electronic medical records of patients who underwent FETOR from January 2008 to July 2011 were retrospectively reviewed. Outcome assessments included the visual analog scale (VAS) for average pain, pain at rest, and pain experienced during hard work or heavy lifting; the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; and pain-free grip strength. Preoperative and postoperative data were compared. RESULTS: A total of 22 elbows in 20 patients with a mean age of 48.8 years (range, 29-58 years) were included. At a mean follow-up of 35.6 months (range, 16-77 months), the VAS score decreased by 93% for average pain, 94% for pain at rest, and 83% for pain during hard work or heavy lifting (P < .001). The patients' perception of arm function as assessed using the DASH recovered to the level of the healthy population (from a mean of 51.6 ± 18.0 to 8.0 ± 11.1; P < .001). The mean pain-free grip strength improved significantly from 53.7% ± 30.3% to 97.3% ± 19.8% of the uninvolved arm (P < .001). Eighteen (90%) patients were satisfied with the surgical outcomes, while 2 patients changed their jobs because of decreased elbow function. No major complications occurred. CONCLUSION: The FETOR technique is an effective and safe method for the treatment of chronic recalcitrant medial epicondylitis.
