  • 手术治疗两例陈旧性肘关节恐怖三联征

    目的总结2例陈旧性肘关节恐怖三联征的手术方法及疗效。 方法2012年8月及2013年10月共收治2例陈旧性肘关节恐怖三联征,男女各1例,年龄分别为46岁及47岁,病程2个月及8个月。其中1例采用肘后侧入路,复位肘关节,同时复位桡骨头和冠突骨折并内固定,修复损伤侧副韧带;1例采用外侧切口复位肘关节,同时复位固定肱骨小头骨折,并作内侧切口复位固定尺骨冠突骨折。术后均行肘关节功能锻炼。 结果2例均于术后4个月骨折愈合,分别获随访15个月及10个月。肘关节功能均恢复良好,Mayo肘关节功能评分分别为78分和85分,评定为良。 结论对于陈旧性肘关节恐怖三联征,通过手术复位肘关节,尽量解剖复位内固定骨折,修复损伤侧副韧带,术后积极功能锻炼,肘关节功能均可改善。

  • Advances in clinical diagnosis and treatment of chronic osteomyelitis in adults

    ObjectiveTo review the progress of clinical diagnosis and treatment of chronic osteomyelitis in adults.MethodsThe literature related to chronic osteomyelitis in recent years was extensively reviewed, and the clinical diagnosis and treatment methods were summarized.ResultsClinical characteristics and laboratory examination can help to diagnose chronic osteomyelitis in adults. Pathogenic identification is the basis for choosing antibiotics. Diagnostic imaging is specific. The treatment includes systemic treatment and local treatment, and the local treatment is the key to radical cure.ConclusionThe diagnosis of chronic osteomyelitis in adults should be made as early as possible. According to the anatomical and physiological classification of the patients, the appropriate treatment plan should be made.

  • 小腿后内侧筋膜皮瓣移位修复后跟离断一例

    正文:足跟部离断损伤临床少见,离断跟部可通过再植修复,若缺乏再植条件,也可采用组织瓣移位重建跟部外观和功能。2010 年7 月,我科收治1 例后跟部分离断患者,缺乏再植条件,经剔除皮肤软组织后将跟骨原位回植,缝接跟腱后,设计小腿后内侧筋膜皮瓣移位修复获得成功。报告如下。

  • PRELIMINARY STUDY ON APPROPRIATE CONCENTRATION GRADIENT OF NERVE GROWTH FACTOR IN PROMOTING FRACTURE HEALING

    Objective To study the effect of local appl ication of different concentrations of nerve growth factor (NGF) on fracture heal ing, and to further search for the appropriate concentration gradient of NGF to promote fracture heal ing. Methods Seventy-five adult male Sprague Dawley rats, weighing (220.0 ± 2.5) g, were made the right tibia fracture model at 1 cm distal from the tibial tubercle and randomly divided into 5 groups (groups A, B, C, D, and E, n=15). Fractures were treated with 0.3 mL normal sal ine containing different concentration of NGF (0.006 48 × 10-2, 0.032 40 × 10-2, 0.162 00 ×10-2, and 0.810 00 × 10-2 μg/g) in groups A, B, C, and D, respectively, and the same amount of normal sal ine in group E. After2, 4, and 6 weeks, the specimens were harvested from 5 rats of each group to perform the biochemical test and histological observation. Before the rats were sacrificed, the arteriovenous blood was taken from the eye-ball to test the alkal ine phosphatase (ALP) activity. Results After 2, 4, and 6 weeks, the gross observation showed that the size and hardness of bone tissue and callus tissue growth gradually increased in groups A, B, C, and D, and group D was higher than groups A, B, C, and E. The X-ray films showed that the calcified area gradually increased in groups A, B, C, and D, and group D was higher than groups A, B, C, and E. The histological observation showed that the trabecular qual ity and maturity in group D were better than those in groups A, B, C, and E. Group D was significantly higher than groups A, B, C, and E (P lt; 0.05) in the gray values of callus tissue and the calcium content of callus tissue at 4 and 6 weeks, in the wet weight of callus tissue at 2 and 4 weeks, and in the ALP content of serum at 2 weeks. The trabecula surface index of osteoblast, the trabecular volume, and the trabecular width decreased as time in the order of groups A, B, C, and D, which were higher than those of group E; group D was the highest, showing significant differences when compared with the other groups (P lt; 0.05). Conclusion The local appl ication of NGF can promote fracture heal ing in rats. The high concentration gradient of NGF (0.810 00 × 10-2 μg/g) has an obvious promotion role on fracture heal ing.
