Effects of local vibration and pulsed electromagnetic field on bone fracture: A comparative study.

The effectiveness of various therapeutic methods on bone fracture has been demonstrated in several studies. In the present study, we tried to evaluate the effect of local low-magnitude, high-frequency vibration (LMHFV) on rat tibia fracture in comparison with pulsed electromagnetic fields (PEMF) during the healing process. Mid-diaphysis tibiae fractures were induced in 30 Sprague-Dawley rats. The rats were assigned into groups such as control (CONT), LMHFV (15 min/day, 7 days/week), and PEMF (3.5 h/day, 7 days/week) for a three-week treatment. Nothing was applied to control group. Radiographs, serum osteocalcin levels, and stereological bone analyses of the three groups were compared. The X-rays of tibiae were taken 21 days after the end of the healing process. PEMF and LMHFV groups had more callus formation when compared to CONT group; however, the difference was not statistically significant (P = 0.375). Serum osteocalcin levels were elevated in the experimental groups compared to CONT (P ≤ 0.001). Stereological tests also showed higher osteogenic results in experimental groups, especially in LMHFV group. The results of the present study suggest that application of direct local LMHFV on fracture has promoted bone formation, showing great potential in improving fracture outcome.

Enhanced postoperative recovery pathways in emergency surgery: a randomised controlled clinical trial.

BACKGROUND: Enhanced recovery pathways are now widely used in elective surgical procedures. The feasibility of enhanced postoperative recovery pathways in emergency surgery for perforated peptic ulcer disease was investigated in this randomized controlled clinical trial. METHODS: Patients with perforated peptic ulcer disease who underwent laparoscopic repair were randomized into 2 groups. Group 1 patients were managed with standard postoperative care and group 2 patients with enhanced postoperative recovery pathways. The primary endpoints were the length of hospital stay and morbidity and mortality. RESULTS: Forty-seven patients were included in the study. There were 26 patients in group 1 and 21 in group 2. There were no significant differences in the morbidity and mortality rates, whereas the length of hospital stay was significantly shorter in group 2. CONCLUSIONS: The application of enhanced postoperative recovery pathways in selected patients with perforated peptic ulcer disease who undergo laparoscopic Graham patch repair seems feasible.
