Clinical efficacy analysis of transverse tibial bone transport combined with vacuum drainage for the treatment of diabetic foot ulcer / 中国骨伤

<p><b>OBJECTIVE</b>To investigate clinical effect of transverse tibial bone transport micro vessels regeneration technology combined with vacuum drainage in treating diabetic foot ulcer.</p><p><b>METHODS</b>From November 2015 and December 2016, clinical data of 19 diabetic foot ulcer patients treated with transverse tibial bone transport micro vessels regeneration technology combined with vacuum drainage were retrospective analyzed, including 15 males and 4 females aged from 42 to 82 years old with an average of (64.57±7.14) years old;the courses of diabetic ranged was (14.62±6.19) years;12 cases on the left side and 7 cases on the right side;the area of ulcer ranged from 2 cm×3 cm to 8 cm×6 cm. All patients were stage D according to Texas classification, 3 cases were grade 2, 10 cases were grade 3 and 6 cases were grade 4. Ankle-brachial index and Michigan Neuropathy Screening Instrument (MNSI) were used to evaluate recovery of peripheral vessel and nerve before and after operation, the result of angiography and vascular ultrasound were also compared after operation.</p><p><b>RESULTS</b>Seventeen of 19 patients were followed up from 3 to 13 months with an average of 6.9 months. Seventeen patients' surface wound were healed. Ankle-brachial index was increased from (0.51±0.20) before operation to (0.93±0.18) at 3 months after operation, and had significant difference(=13.63, =0.000);MNSI was increased from (4.06±1.36) before operation to(5.76±1.44) at 3 months after operation, and differences were statistically significant (=7.31, =0.000). Postoperative angiography and vascular ultrasound showed satisfied regeneration of micro-vessel and affected foot achieved normal movement and daily life.</p><p><b>CONCLUSIONS</b>Transverse tibial bone transport micro vessels regeneration technology could reconstruct micro-vessel under lower affected limb, promote recovery of peripheral vessel and nerve, while with vacuum drainage could promote wound healing, has advantages of simple operation, obvious clinical effect, and high success rate of limb-salvage, and is one of ideal treatment for diabetic foot ulcer.</p>

Ilioinguinal approach versus Stoppa approach for open reduction and internal fixation in the treatment of displaced acetabular fractures: A systematic review and meta-analysis / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>To compare the efficacy and safety of open reduction and internal fixation through ilioinguinal approach and Stoppa approach for the treatment of displaced acetabular fractures.</p><p><b>METHODS</b>Case-controlled trials (CCTs) published from January 2010 to August 2015 that compared the ilioinguinal approach and Stoppa approach in the management of displaced acetabular fractures were retrieved from the databases of Cochrane Library, Pubmed, CNKI, and so on. Methodological quality of the trials was critically assessed. Statistical software RevMan 5.0 was used for data analysis.</p><p><b>RESULTS</b>Eight articles were included in the meta-analysis. Through comparing the efficacy and safety of ilioinguinal approach and Stoppa approach in the treatment of displaced acetabular fracture, statistical significance was found in the average operation time [WMD = 68.29, 95% CI (10.52, 126.05), p < 0.05] and the median intraoperative blood loss [WMD = 142.26, 95% CI (9.30, 275.23), p < 0.05]. However, there existed no statistical significance in the fracture end reset satisfaction rate [RR = 0.63, 95% CI (0.17, 2.37), p > 0.05], the early complications rate [RR = 0.89, 95% CI (0.33, 2.40), p > 0.05], the late complications rate [RR = 0.91, 95% CI (0.27, 3.01), p > 0.05], and Harris hip score good function rate [RR = 0.52, 95% CI (0.25, 1.10), p > 0.05].</p><p><b>CONCLUSION</b>Though both techniques can obtain satisfactory clinical functions in the treatment of displaced acetabular fractures, Stoppa approach is superior to the ilioinguinal approach in terms of operation time and intraoperative blood loss.</p>
