Socio-economic burden of permanent incisor replantation on children and parents

Abstract – This study describes the socio‐economic burden and attitudes of children and their parents following replantation of avulsed incisors. Records of 80 patients with 99 avulsion injuries treated in a teaching hospital clinic from 1988 to 1999 were reviewed. Mean age at time of injury was 10.6 years (range = 6.6–17.7 years). Complete records for a minimum of 1 year were obtained for 43 patients with 60 replanted incisors. Mean treatment procedures provided during the first year included 5.5 diagnostic periapical radiographs, 1.9 occlusal radiographs, 1.3 pulpectomies, and 2.7 pulp medicament applications. The mean estimated treatment cost and direct time (dentist) for first‐year post‐trauma management was $1465 CAD and 7.2 h, respectively. Treatment costs were significantly higher during the first year post‐trauma for patients who had their incisors extracted (P = 0.04), but there was no significant difference in direct treatment time between the two groups (P = 0.19). Twenty‐one patient–parent pairs were surveyed for a number of qualitative factors. Ninety per cent of patients and 86% of parents reported that school and work time was lost. Even after having gone through the painful experience of replantation, the demands of recall, and in some cases, extraction, the majority of patients (67%) and parents (81%) stated that they would have still made the same (replantation) decision. Patient and parent responses were not statistically different (P = 0.453). Almost half the parents stated they would be willing to pay over $2000 CAD to save an incisor. Patients rated retention of an incisor as significantly more important than infraocclusion. This is the first study to quantify the treatment burden of replantation of avulsion injuries exclusively in the pediatric population. This study describes the socio‐economic burden and responsibilities of patient/parent and dentist and their role in informed consent.     

动脉灌注灭活再植治疗骨肉瘤的体会

本组１２例骨肉瘤均采用动脉区域灌注灭活再植及术后化疗方法，术后２年存活率平均为７５％，１例因经验不足致局部复发，仅占８．３％，表明在化疗保障下，采用此种方法即能保肢，又能获得与截肢治疗相同的手术效果，优于单纯行灭活再植术后中方法。     

Histometric study of root resorption on human premolars following experimental replantation

Abstract – A histometric method was applied for evaluation of root resorption in 57 experimentally replanted teeth and 22 controls. Representative axiobuccolingual sections were selected for measurement of resorptions at a magnification of × 40. The frequency of root resorption in the control teeth was low. In replanted teeth marked resorptive activity elicited by the trauma appeared after 2 wk. The extent of active resorptions increased until the third postoperative week. On an average 14% of the root periphery was affected at this stage. After the sixth postoperative week progressive cement deposition took place in the resorption lacunae. Incidental ankylosis of the periodontal membrane also occurred from this observation time but there was no increase among the long-term groups.     

逆行隐神经岛状皮瓣的临床应用

目的 报告逆行隐神经岛状皮瓣的临床应用结果。方法 应用这种技术修复6例足跟部软组织缺损,切取的皮瓣面积为4cm×6 cm至7cm×10 cm。结果 所有的皮瓣完全成活,取得了满意的效果。1例术后4d发生表浅感染,经换药愈合。结论 大隐静脉、隐神经和伴行的动脉网是该皮瓣的轴,该皮瓣具有血管解剖恒定、血管蒂长和操作简单等优点,而且较薄,适宜修复足部软组织缺损。     

瘤体骨切除灭活再植治疗四肢长骨巨细胞瘤

体内刮除及灭活植骨治疗骨巨细胞瘤（ＧＣＴ）的复发率高。我科从１９８６年６月～１９９６年２月治疗四肢长骨ＧＣＴ２４例。随访１１个月～８年４个月。其中７例采用局部切刮体内灭活植骨和（或）骨水泥充填治疗。结果１例感染，６例复发，１例恶变后死于肺转移。作者自１９９１年１月采用瘤体骨切除，离体灭活再植，与骨残端体内灭活相结合，骨缺损采用自家腓、髂骨移植，Ｌ－梯形加压钢板（Ｌ－ＴＣＰ）或梯形加压钢板（ＴＣＰ）固定治疗１７例，其中１２例保留关节，５例做膝关节融合。本组无菌创口感染１例，１例复发。在保留关节的１２例中９例关节功能恢复优良，１例尚可，２例差。充分说明瘤段骨切除体外灭活再植术疗效确实，复发率低。保留关节术式适于关节破坏较轻（＜＝１／２）者，结合关节残端体内灭活和有效的骨结构重建，有利于恢复关节功能。如关节面累及＞１／２，宜做骨关节端切除，灭活再植，下肢宜做关节融合或人工关节置换术。

血管缺损断指的回植

某些断指的伤情复杂，常合并血管缺损，回植难度大。我们在微血管移植动物实验和尸体手指显微解剖的基础上，据情分别采用了１２种方法，修复断指中血管缺损共２０７例（２６１指），成活２４０指，成活率９２％。我们认为精湛的显微外科技术和正确选择处理方法，是手术成功的关键。     

第二足趾跖侧菱形皮瓣转移改形法再造拇指
