BACKGROUND:Crainocerebral missile wound (CMW) is the common severe trauma of war. Environmental factor is the important factor that aggravates the development of sickness and threatens the life of the sick and wounded at early stage. The study on basic theory and treatment of CMW under hyperthermia and high-humidity is the major task in military medicine.OBJECTIVE: To observe the characters of bacterial growth in wound cavity and peripheral tissue after CMW in cats under hyperthermia and high-humidity so as to provide the reference data to the tissue repair and its functional recovery in CMW.DESIGN: Randomized controlled experiment.SETTING: Surgery Department of Neurology in Zhujiang Hospital affiliated to Southern Medical University(First Military Medical University).MATERIALS: The experiment was performed in Department of Tropical Medicine and Hygiene in Southern Medical University from April to May 2003. In the experiment, 24 hybrid cats were employed, of clean grade, of either sex, body-weighted (2.5±0.2) kg, provided from Experimental Animal Center of Southern Medical University. The animals were randomized into 4 groups, named the control at common temperature (5 cats), common temperature group (8 cats), hyperthermia and high-humidity group (8 cats) and blank control (3 cats).METHODS: After weighted, the cat was injected abdominally with 30 g/L pentobarbitol sodium solution at 30 mg/kg. After successful establishment of craniocerebral blindgut wound model, in common temperature group, the cats were placed in simulated climatic cabin at 25 ℃ and 50% relevant humidity for 6 hours and in hyperthermia and high-humidity group, the cats were placed in the hyperthermia and high-humidity environment for 6 hours. With biopsy, the fragmented brain tissue in wound tract and the brain tissue on the wall of wound tract far from 0-5 mm and 5-10 mm were collected and preparedinto successively natural solution and homogenate, and counting was done in 24 hours of bacterial culture to calculate bacterial content in wound cavity and peripheral tissue. In blank control, the cats were sacrificed with anesthesia and the material was collected directly, the rest steps were same as the control at common temperature.MAIN OUTCOME MEASURES: Bacterial content in wound cavity and peripheral tissue in each group.RESULTS: Totally 23 animals were employed in outcome analysis. Bacterial contents in same regions were different remarkably in different groups (F=171.423, P=0.000). It was indicated in paired comparison that significant difference happens between the control at common temperature, common temperature group and hyperthermia and high-humidity group and blank control successively (P ＜ 0.01). The difference was not significant in the comparison among the control at common temperature, common temperature group and hyperthermia and high-humidity group (P ＞ 0.05). Bacterial contents at different distances from the wound cavity were different remarkably in each group (F=14.865, P = 0.000).CONCLUSION: Hyperthermia and high-humidity does not impact significantly the bacterial growth of CMW in 6 hours and bacterial reproduction has not entered high-rate increasing stage yet, due to which, it is still safe for debridement repair.

Objective To evaluate the significance of weight-bearing lateral radiographs in evaluation of malunited frac-tures of the ankle. Methods 17 patients with malunited fractures of the ankle were treated by different reconstructive operations be-tween March 2010 and October 2012, including 9 females and 8 males, aged from 17 to 64 years. According to the Takakura classifi-cation of ankle arthritis, there were 7 patients in grade 1, 4 in grade 2 and 6 in grade 3. Simple open reduction and internal fixation were performed in 5 patients, supramalleolar tibial osteotomy in 5, lengthening osteotomy of the fibula in 2, supramalleolar tibial and fibular osteotomy in 5. Tibiofibular clear space on the anteroposterior radiograph. Medial clear space, tibiofibular clear space and tib-iofibular overlap on ankle mortise radiographs were compared preoperatively and at last follow-up. Tibial lateral surface angle (TLS), the offset of the center of talar rotation from the tibial axis, and the displacement of tibiotalar articular surface center on weight-bear-ing lateral X-ray were also compared preoperatively and at last follow-up. AOFAS score was used to evaluate the function of the ankle. Results The duration of follow-up was 9 to 32 months. Bone healing was observed in all patients, and the average healing time was 11 to 14 weeks. Ankle joint degeneration grade had no exacerbation. The medial clear space, tibiofibular clear space and tibiofibular overlap had no significant difference between the pre and postoperative. Statistically significant change was seen postoperatively in the values of TLS (76.9°±4.1° vs 80.9°±5.2°). The offset of the center of rotation from the tibial axis and the displacement of tibiotalar articular surface center were changed from 10.8 ± 2.1 mm to 2.0 ± 0.5 mm and 4.5 ± 1.5 mm to 2.2 ± 1.0 mm, respectively. The average AOFAS score was improved from 45.7 ± 15.9 points preoperatively to 82.0 ± 9.9 points postoperatively. Conclusion Weight-bearing lateral radiographs can be used to judge the ankle restoration. Even if the mortise radiograph had relative good realignment, it may ap-pear obvious deformity on lateral radiographs. Good reduction of lateral radiographs requires that the mid axis of the tibia should pass through the center of talar rotation and tibiotalar articular surface be parallel on the lateral radiograph.
