烧伤后手指瘢痕挛缩畸形综合治疗的临床研究

目的通过比较手术结合康复综合治疗方案与常规治疗方案对烧伤后手指瘢痕挛缩畸形的治疗效果,探讨综合治疗的优越性及经验。方法1999年6月~2004年6月,共56例烧伤后手指瘢痕挛缩畸形患者纳入试验。综合治疗组(A组)28例,男20例,女8例;年龄14~47岁,平均31岁;患手共47只129指,以手术结合系统康复治疗。常规治疗组(B组)28例,男17例,女11例;年龄18~51岁,平均30岁;患手共42只107指,采用常规手术,术后仅作简单的康复性锻炼指导,由患者在院外自己完成功能锻炼。采用Swanson法对患指运动功能进行评定,九孔柱试验法对患手整体运动功能进行评定,比较两组患者治疗前后手指和手整体运动功能的差异。结果A组患者术后均获随访12~19个月,B组患者均获随访13~20个月。治疗前A组患指的强直失能指数(indexofankylosis,IA)值为82%±20%,B组为78%±17%;治疗后A组为45%±13%,B组为52%±14%;治疗前后A组IA差值为37%±15%,B组为26%±15%,两组比较差异有统计学意义(P<0.05)。治疗前A组九孔柱测量值28.34±5.62s,B组为27.47±5.78s;治疗后A组为20.73±4.25s,B组为21.86±4.12s;治疗前后A组九孔柱测量差值为7.61±2.27s,B组为5.61±2.94s,两组比较差异有统计学意义(P<0.05)。结论烧伤后手指瘢痕挛缩畸形采用手术结合康复综合治疗的效果明显优于常规治疗,值得推广。

Characteristics of patients with congenital clasped thumb: a prospective study of 40 patients with the results of treatment

Purpose  Congenital clasped thumb is a deformity that is associated with heterogeneous congenital anomalies and it has been addressed in many congenital syndromes. The aim of this study was to diagnose and evaluate cases of clasped thumb as regards the associated congenital anomalies and syndromes, and evaluation of the results of treatment of such cases. Methods  A prospective study on 40 patients with 73 clasped thumbs was done. All the patients’ data regarding their personal, family, pregnancy and developmental histories were recorded. All the patients were exposed to thorough clinical and radiological examination and genetic assessment. The cases were classified using the Tsuyuguchi et al. (J Hand Surg [Am] 10:613–618, 1985) classification into three types. Conservative treatment was adopted in ten hands, and surgical treatment was performed for 28 hands in 17 patients, with an average follow-up of 26 months. Results  Positive consanguinity was recorded in 57.5% of cases. Associated anomalies were recorded in 77.5% of cases. Type I was the most common one, followed by type III and then type II. Conservative treatment is effective in type I cases when presented early, and all patients were satisfied with the results of surgical treatment. Conclusions  We reported associated anomalies which are to our knowledge have not mentioned before in the literature which include; congenital blindness, radial deviation of the index finger and ventricular septal defect. We found that 68% of the patients had associated syndromes, and this has not been mentioned before. In this study, we found that there were no difference between type II and type III clasped thumb as regards the pathological findings, severity, the operative procedures, the treatment protocol and the operative results. Properly planned treatment gives satisfactory results.

经尿道前列腺电切术后膀胱颈挛缩多因素分析

目的 :对经尿道前列腺电切术 (TURP)后膀胱颈挛缩 (BNC)发生的各种可能因素进行分析 ,探讨减少该并发症的途径。　方法 :对 10 17例行TURP患者中发生BNC的 2 4例进行统计学分析 ,在手术方法、前列腺电切重量、单位时间前列腺组织电切重量、置管时间、高频发生器类型及有无糖尿病、尿潴留及前列腺炎等方面进行比较 ,了解其可能发生的因素。　结果 :TURP术后BNC发生率明显高于开放手术病例 ,小前列腺、单位电切时间长、高频发生器功率大及术前前列腺炎患者易发生BNC(P <0 .0 5 ) ,而术前尿潴留、糖尿病及术后置管时间对BNC发生无明显影响 (P >0 .0 5 )。　结论 :小前列腺、前列腺炎及电流损伤是发生BNC的重要因素 ,患者的选择及熟练精确的电切技术可减少BNC的发生。     

Joint capsule matrix turnover in a rabbit model of chronic joint contractures: Correlation with human contractures.

To evaluate changes in matrix molecules of the joint capsule, the right knees of 24 skeletally mature female NZW rabbits were immobilized while the contralateral limb served as an unoperated control. The immobilization was discontinued at 8 weeks and the rabbits were divided among four groups (n = 6) based on the number of weeks the right knees were remobilized: 0, 8, 16, or 32. Three rabbits (six knees) that did not have operations provided normal control joint capsules. The mRNA levels for collagen types I, II, and III, and MMP-1 and -13 were significantly increased in the joint capsules of the contracture knees in all groups when compared to normal and contralateral limb joint capsules. In contrast, the mRNA levels for TIMP-1, -2, and -3 were decreased in the joint capsules of the contracture knees in all groups when compared to normal and contralateral limb joint capsules. The mRNA levels for lumican and decorin were increased in the joint capsules of the contracture knees in all groups when compared to normal capsules. Many of the changes observed in this animal model are similar to those observed in human joint capsules from posttraumatic elbow contractures, supporting the value of this rabbit model.     

联合肩胛/肩胛旁分叶皮瓣修复严重颌颈部瘢痕挛缩

目的探讨临床应用联合肩胛/肩胛旁分叶皮瓣显微修复严重颌颈部瘢痕挛缩畸形,并重建颈部三维活动功能及轮廓外观的方法和疗效。方法2003年1月~2004年11月,收治9例严重颌颈部瘢痕挛缩畸形患者,年龄9~32岁。病程2~18年。瘢痕挛缩程度为3~4度。行瘢痕切除,对颈部挛缩组织松解复位所致软组织缺损创面采用联合肩胛/肩胛旁分叶皮瓣进行解剖分区的显微修复。分叶皮瓣范围最大分叶皮瓣为20cm×8cm~20cm×11cm,最小分叶皮瓣为15cm×4cm~15cm×6cm。结果9例患者有8例分叶皮瓣成活,1例肩胛皮瓣远端发紫,经换药加压包扎后成活。其中8例术后获3~9个月随访,畸形无复发,颌颈角恢复至90~105°;3例行二期皮瓣臃肿修整手术。患者对术后颌颈部外观和功能均满意。结论对于严重颌颈部瘢痕挛缩畸形,联合肩胛/肩胛旁分叶皮瓣可提供足够的组织覆盖,有可靠的血管蒂,对于重建颌颈部功能和外形,是一种较好的手术选择。
