第1跖列稳定术联合第2-5跖骨头切除术治疗晚期类风湿关节炎前足畸形

目的:介绍第1跖列稳定联合第2-5跖骨头切除术治疗晚期类风湿关节炎(rheumatoid arthritis,RA)前足畸形的手术方式并对中短期临床疗效进行评价。方法:2006年10月至2010年8月收治的晚期RA前足畸形97例患者进行回顾性分析。其中,男9例,女88例;单足65例,双足32例;年龄36～67岁,平均54岁;病程6～32年,平均17年。所有病例存在严重的拇外翻同时合并第1跖跗关节不稳,第2-5跖趾关节脱位及僵硬。采用第1跖列稳定联合第2-5跖趾关节成形术对其进行治疗。通过影像学资料测量拇外翻角(Hallux valgus angle,HVA),跖骨间角(intermetatarsal angle,IMA),并采用JSSF(Japanese Society for Surgery of the Foot)评分对临床疗效进行评估。结果:97例患者中失访5例(7足),平均随访37个月(6～52个月),其中1例术后1年因急性心肌梗死死亡。术前JSSF评分(33.2±8.2)分,末次随访时改善至(67.3±3.1)分(P<0.01);HVA由术前(50.0±11.8)°纠正至术后(21.2±3.2)°(P<0.01);IMA由术前(15.5±3.6)°纠正至术后(9.7±6.6)°(P<0.01)。发生跖趾关节骨不连4足;术后8～11月摄片发现第1楔骨内高密度改变3足;出现拇内侧切口延迟愈合9足;跖趾关节内固定感染2足;跖跗关节内固定感染1足;第2-5跖趾关节术后16足畸形复发。结论:晚期RA患者的前足病变涉及范围广,畸形严重。采用第1跖趾关节融合联合Lapidus术式重建第1跖列的外形及稳定性,跖骨头切除术纠正第2-5跖趾关节畸形的方式重建前足疗效可靠。该术式适用于重度拇外翻合并IMA增大及第1跖跗关节不稳,同时存在第2-5跖趾关节僵硬性半脱位的患者。

Keller手术治疗外翻疗效分析

目的 观察Keller手术治疗(足母)外翻疗效。方法 对我院1978年1月-1995年12月间因(足母)外翻住院并行了Keller矫形术的病人进行随访,共随访到70例(118足)有效病人。术后时间为5～24年,平均9年,对(足母)趾及前足部症状改善,畸形矫正程度,足趾功能及术后各种并发症进行统计和分析,同时通过负重足印观察比较Keller矫形术对前足负重点的影响。结果Keller手术后病人(足母)趾及前足症状改善,(足母)外翻及叠趾畸形、矫正满意者98足,手术优良率为83％。并发症主要为(足母)趾麻木,(足母)外翻复发或未矫正,(足母)内翻,(足母)抓地力量弱,第二趾屈曲挛缩等,部分病人需要再次手术。结论 Keller手术通过(足母)跖近节趾骨截骨及(足母)跖趾关节成形,以达到(足母)外翻矫正的目的。对年龄较大、(足母)外翻严重,或同时合并(足母)跖趾关节骨关节炎的患者是一个较好的治疗方法。近节趾骨截骨是手术成功的关键。     

膝关节外翻畸形的人工全膝关节置换术

目的探讨膝关节外翻畸形患者行人工全膝关节置换术(TKA)的手术方法和临床效果。方法对1996年1月至2004年8月74例87个膝关节外翻畸形TKA手术进行回顾分析。患者男11例,女63例,平均年龄63岁(26~80岁);股胫角(股骨和胫骨解剖轴线的夹角)平均为21·59°(12°~40°);应用后稳定型假体,采用髌旁内侧入路、常规截骨加单纯外侧软组织松解方法。随访检查膝关节活动度、X线外翻角度及KSS评分以评价手术效果。结果术后评价随访时间33·8个月(5个月~9年),根据膝关节活动度数及KSS评分评估关节功能情况。膝关节平均活动度为112·4°(80°~130°),KSS评分平均为81·7分(71~93分),比术前提高了59分;功能评分平均为86·3分,比术前提高了59·8分。所有膝关节在行TKA后外翻畸形基本得到矫正,随访时外翻度数(股胫角)平均为8·7°(0°~11°),较术前有明显改善。随访时1例患者有膝关节轻度不稳症状,1例术前严重髌脱位患者术后髌骨存在半脱位,其余正常。结论对于膝关节外翻畸形患者,采用髌旁内侧入路、常规截骨加单纯外侧软组织松解以及安装后稳定型假体的方法,可取得比较满意的临床效果。     

Fusion or gemination? An unusual mandibular second molar

Fusion and gemination is not an uncommon finding and affected most primary dentition and the permanent maxillary incisors. These changes can develop a series of complication. A 11-year-old male presented radiography finding: an unusual mandibular second molar. A well-documented case brings a challenge for radiologists classify between fusion and gemination. In conclusion, this alteration although common in other regions, there are no case in the literature involving “second and third” molar.     

特重度烧伤后伴多处严重畸形的功能重建

To explore new measures for functional reconstruction of multiple severe deformities as a result of extensive deep burn( total burn surface area ≥90% TBSA, including deep burn ≥ 70% TBSA)in late stage. Twelve severe bum patients with above-mentioned deformities were hospitalized in our ward during 1960 ～ 2005,the sears resulted from bums were distributed from head to foot with 173 deformities, including 27 scar ulcers. All patients lacked of self-care ability, among them some could not stand. Due to inadequate skin source, deformities were corrected by skin from matured scars expanded with subcutaneous balloon at late postburn stage. Following our former clinical experience, anatomic investigation and experimental re search, we chose the following methods to correct deformities and restore functions: application of split-thickness scar skin after expansion(88 wounds) ; use of sear skin flap/scar-Achilles tendon flaps (59 wounds) ; combination of thin split-thickness skin grafts from scar and allogeneic acellular dermal matrix (composite skin,40 wounds).All grafts survived, the appear ance and function were improved obviously without complica tions. Follow-up 1～ 40 years, all patients could take care them selves with satisfactory function and appearance, and among them 8 patients returned to work ( one had worked for 40 years),2 pa tients married and had children. The above-mentioned measures are safe, reliable and effective for functional reconstruction of deformities.

Recommendations for starting a grown up congenital heart disease (GUCH) unit

During the last decades, advances in diagnosis and treatment of congenital heart disease have allowed many individuals to reach adulthood. Due mainly to the great diagnostic diversity and to the co-morbidities usually present in this age group, these patients demand assistance in a multidisciplinary facility if an adequate attention is aimed. In this paper we reviewed, based in the international literature and also on the authors’ experience, the structural conditions that should be available for these patients. We highlighted aspects like the facility characteristics, the criteria usually adopted for patient transfer from the paediatric setting, the composition of the medical and para- medical staff taking into account the specific problems, and also the model of outpatient and in-hospital assistance. We also emphasized the importance of patient data storage, the fundamental necessity of institutional support and also the compromise to offer professional training. The crucial relevance of clinical research is also approached, particularly the development of multicenter studies as an appropriate methodology for this heterogeneous patient population.
