Objective To analyze the injury types and radiologic findings of the wounded in the major Wenchuan earthquake of May 12, 2008. Methods Radiologic results of 1013 victims admitted to MianYang Central Hospital from May 13, 2008 to May 19, 2008 were studied retrospectively, including X-ray of 854 cases (about 2900 local exam positions) and CT scan of 259 cases (about 300 local exam positions). Results 733 cases showed radiologic abnormalities, including 527 cases of single region injury (accounting for 52. 0%) and 206 cases of multi-region injury (accounting for 20. 3%), the overall positive rate was 72. 4%. The results were in the following order on the basis of the incidence, 288 cases of lower extremity injuries (28.4%), 151 cases of thoracic injuries(14. 9%), 136 cases of upper extremity injuries(13.4%), 133 cases of spine fracture(13.1%), 114 cases of pelvic fracture and dislocation(11.3%),88 cases of craniocerebral injuries (8. 7%), 25 cases of maxillofacial fracture (2. 5%) and 8 cases of abdominal tranma(0. 1%). Thoracic injuries included: rib fracture in 136 cases, pulmonary injury in 59 cases, and sternal fracture in 3 cases. Spinal fracture included: cervical vertebrae involved in 12 cases,thoracic vertebrae involved in 43 cases, lumbar vertebrae involved in 93 cases, and Sacrococcygeal vertebraeinvolved in 12 cases. Craniocerebral injuries included: skull fracture in 41 cases, endocranial abnormalities in 72 cases. Abdominal trauma included: intestinal obstruction in 4 cases, renal contusion in 3 cases and abdominal wall hematoma in 1 case. Conclusion Most parts of the body can be injured by earthquake.Bone fracture and dislocation of lower extremity are the most common manifestations.

BACKGROUND:Diabetic foot patients with wound infections constitute a large patient population,and there is currently no satisfactory treatment approach. OBJECTIVE:To investigate the clinical efficacy of a modified tibial cortex transverse transport combined with antibiotic-loaded bone cement for treating refractory diabetic foot ulcers. METHODS:A total of 46 diabetic foot ulcers patients,27 males and 19 females,with an average age of 64.37 years,were selected from Beijing Chaoyang Hospital,Capital Medical University and Beijing Chaoyang Integrative Medicine Rescue and First Aid Hospital from January 2020 to January 2023.All of them underwent the modified tibial cortex transverse transport combined with antibiotic-loaded bone cement treatment.Ankle-brachial index,WIFi(Wound/Ischemia/Foot infection)classification,pain visual analog scale score,and ulcer area were recorded before and 3 months after surgery. RESULTS AND CONCLUSION:(1)The mean ulcer healing time for the 46 patients was(58.07±24.82)days.At 3 months postoperatively,there were significant improvements in ankle-brachial index,pain visual analog scale score,ulcer area,and WIFi classification in 46 patients,as compared to the preoperative values,with statistically significant differences(P<0.05).Two patients experienced pin-tract infections,without infection or ulcer recurrence during the follow-up period.(2)These findings indicate that the modified tibial cortex transverse transport combined with antibiotic-loaded bone cement effectively alleviates patients'pain,improves lower limb circulation,controls infections,and promotes ulcer healing.

Objective To assess the effectiveness of enhanced tibial transverse transport(TTT)in con-junction with vacuum-assisted closure(VAC)therapy for managing recalcitrant diabetic foot ulcers.Methods A retrospective analysis was conducted on data from diabetic foot patients with Wagner grade≥2 who were treated at Beijing Chaoyang Hospital and Beijing Chaoyang Hospital of Integrated Traditional Chinese and Western Medicine between July 2020 and December 2022.The patients were categorized into three groups based on their treatment regimen:VSD treatment(VSD group),modified TTT treatment(TTT group),and combined application of TTT and VSD(combined group).A one-year follow-up was performed to assess general data,ulcer area before and three months after surgery,ankle brachial index,visual analog pain score,as well as adverse events within one year post-surgery among the three groups.Results The VSD group consisted of 43 patients,while the TTT group consisted of 43 patients,and the combined group consisted of 42 patients.There were no statistically significant differences in baseline characteristics among the three groups(P＞0.05).Patients in the VSD group had longer ulcer healing time,higher pain scores,lower ankle brachial index(P＜0.05),larger ulcer area(P=0.029),and higher one-year ulcer recurrence rate compared to those in the TTT group.On the other hand,patients in the combined group had shorter ulcer healing time compared to those in the TTT group(P=0.046).However,there were no significant differences observed between these two groups regarding ulcer area(P=0.362),pain scores(P=0.932),ankle brachial index(P=0.671),and one-year ulcer recurrence rate(P=0.710).Conclusions The efficacy of modified TTT surpasses that of VSD in promoting ulcer healing,alleviating pain,and enhancing lower limb circulation.Furthermore,the combination of VSD with modified TTT demonstrates a potential to further expedite wound healing time.
