经外踝入路关节内环锯法行踝关节融合术

[目的]介绍经外踝入路关节内环锯法行踝关节融合术的方法与临床效果。[方法]利用环锯(14mm、16 mm、18 mm)对20例踝关节严重病损病人行关节融合术,均采用踝关节外侧入路,腓骨下段截骨并下翻显露关节,利用环锯关节内融合即原锯心骨旋转90°原位回植,外踝骨块螺钉固定旁靠植骨。术后关节予以石膏固定。[结果]经随访6个月~4 a,平均26个月。术后2周刀口Ⅰ期愈合,4周可见骨痂形成,12周病人疼痛明显缓解或消失,足部外形改善。X线片示胫距关节牢固融合。[结论]采用经外踝入路关节内环锯法行踝关节融合术,方法简单,融合率高。其优点为:切口显露良好;对胫距关节干扰小,保证了关节的正常高度和下肢长度;锯心骨原位回植无需再次植骨,外踝旁靠植骨提高了植骨强度。     

Roy-Camille腰椎、腰骶椎融合术治疗腰椎滑脱症(附14例报告)

使用Roy-Camille 腰椎、腰骶椎融合术治疗腰椎滑脱14例。采用特制的钢板,一般固定3～4个脊椎。若合并神经根刺激症状可同时作椎板切除、椎间盘摘除、侧隐窝松解术,同时进行丰富的侧后方植骨。经随访平均19个月,均获得骨性融合,无脊髓或神经根损伤等手术并发症。作者认为此手术是治疗腰椎滑脱的比较理想的方法。     

FUSION OF THE FIRST METACARPOPHALANGEAL JOINT FOR POST-TRAUMATIC CONDITIONS

Fusion of the metarcarpophalangeal joint of the thumb is an accepted treatment in the management of instability or osteoarthritis following trauma to this joint. A review was made of the literature and 30 of the senior author's (RH) patients who had had this operation, in order to determine what effect the operation had on the pain in their thumb, any symptoms of instability, interference with work and daily activities, and strength in the hand. All of the patients achieved bony union and the average angle of fusion was 7.6 degrees of flexion. All of the patients were either satisfied or very satisfied with the results of the operation, and had an average increase of 6.3 points on a 12 point rating scale. However, 48% of patients had some mild intermittent pain and 43% complained of some difficulty with fine motor tasks. Twelve patients were able to attend for formal evaluation including the Jebson and Crawford Hand Function Tests which revealed some decrease in hand function in all of those tested. It was concluded that this method of arthrodesis of the metacarpophalangeal joint of the thumb gives reliable results, with high patient acceptance, but does not result in an entirely normal thumb or hand function.     

螺旋CT多平面重建对寰枢椎改良后路经关节螺钉内固定的意义

目的通过对正常人螺旋CT多平面重建检查，并对其行后路经关节螺钉内固定技术相关形态学参数的测量，为临床提供患者个体化手术相关信息。方法对60例正常人进行寰椎的螺旋CT检查，获取相关参数并进行分析。采用枢椎下关节突正中为进钉点模拟寰枢椎后路经关节螺钉内固定术，在螺旋CT重建上获得轴面和矢状面的正确倾斜角度。C2峡部高度和宽度，理想的螺钉长度，理想的螺钉矢状面和轴面倾斜度，以及理想的螺钉路径与椎动脉沟之问距离。结果C2峡部高度为（8．02±1．92）mm，峡部宽度（6．05±1．32）mm，理想的螺钉长度为（41．22±4．48）mm，螺钉矢状面倾斜度为53．87°±5．61°，与内向成角（14．81°±2．81°）。10侧（8％）峡部狭窄（宽度或高度小于5mm），测量其椎动脉沟与理想螺钉途径之间距离，有12例（10％）小于2．5mm，因此总共有22侧（18％）存在潜在椎动脉损伤风险。结论术前对每个患者行CT检查十分必要，能充分地了解个体的解剖结构，提高手术的安全性。     

Tibiotalocalcaneal arthrodesis with retrograde intramedullary nailing

Nineteen patients (20 feet) with severe hindfoot and ankle deformity underwent tibiotalocalcaneal fusion with a retrograde locked intramedullary nail as a limb-salvage procedure. The purpose of this study was to compare the complication rates of this procedure in diabetic versus nondiabetic patients. There were 8 men and 11 women with preoperative diagnoses including Charcot neuroarthropathy, primary osteoarthritis, rheumatoid arthritis, equinocavovarus, posttraumatic osteoarthritis, gouty arthritis, and ankle malunion. Ten of 20 procedures were performed in patients with diabetes. The average patient age was 56 years, and the average postoperative follow-up was 19.8 months. Nineteen of 20 ankles (95%) achieved successful fusion with an average time of 4.1 months. Four patients (21%) required either a fracture brace or an ankle foot orthosis at final follow-up. Five patients (25%) had major complications and 11 patients had minor complications. Major complications included osteomyelitis (n = 2), Charcot arthropathy (n = 2), failure of fixation (n =1), soft-tissue necrosis (n = 1), cardiac arrest (n = 1), cerebral vascular accident (n = 1), and fatal pulmonary embolus (n = 1). All patients with major complications were diabetic, and 14 of 20 combined major and minor complications occurred in patients with diabetes. The complication rate was found to be high in diabetic patients with end-stage deformity undergoing a limb salvage     

侧块钢板螺钉系统在颈椎后路手术中的应用

目的 探讨侧块钢板螺钉系统在颈椎后路手术中应用的临床经验。方法 对1999年2月－2000年3月间共36例行侧块钢板内固定的患者进行回顾分析。29例（80．6％）获得随访,平均随访时间8个月（4－15个月）。29例患者中颈椎病（3节及3节段以上椎间盘突出）20例,黄韧带骨化症（OYL）1例,后纵韧带骨化症（OPLL）2例,颈椎骨折脱位6例。手术时采取坐位,病变节段行全椎板切除减压,保留关节突。钢板螺钉固定于侧块（即关节突）,同时关节突间植骨融合。结果 29例患者共植入124枚螺钉,平均每位患者4．3枚。颈痛明显改善者为18例（20例术前存在颈痛）占90％。术后3－6月X线随访,27例患者关节突间见骨小梁生成,融合率93％。4例患者路侧块钢板螺钉系统能提供较稳定的固定,有效改善颈痛。钢板螺钉松动与神经根损伤是较严重的并发症。只要严格掌握手术适应证与安装技术,颈椎后路钢板固定是治疗颈椎不稳的一种十分有效的方法。     

Medial approach for subtalar distraction bone block arthrodesis

Subtalar distraction bone block arthrodesis is a useful technique commonly employed in the management of calcaneal and talar fracture malunion. Traditionally it is performed via a posterolateral or extensile lateral approach, however such approaches have been associated with wound complications, particularly secondary to the added stress caused by the subtalar distraction crucial to this technique. Medial approaches to the subtalar joint have been used in other procedures but have not been reported in subtalar distraction bone block arthrodesis. A novel case and technique illustrating the medial approach for subtalar distraction bone block arthrodesis is discussed.Level of clinical evidenceLevel 4.
