目的介绍采用内侧髌股韧带(medial patellofemoral ligament,MPFL)重建治疗复发性髌骨脱位的手术技术和效果。方法 2005年6月-2007年9月,采用MPFL重建治疗复发性髌骨脱位29例。男6例,女23例;年龄13～45岁,平均20.3岁。髌骨脱位2～10次。末次髌骨脱位至手术时间为1～144个月,平均43.9个月。术前CT检查测量胫骨结节-股骨滑车间距(tibial tuberosity-trochlear groove distance,TT-TG);并行Kujala、Lysholm和Tegner评分,分别为(72.03±17.38)、(72.65±14.70)、(5.25±1.83)分。手术采用同种异体肌腱作为移植物,在股骨侧使用骨隧道技术,可吸收挤压螺钉固定;在髌骨内侧缘制作双L形隧道,调节移植物张力后,缝合固定移植物的游离端。同时行关节镜检查、游离体取出和髌外侧支持带松解。对于TT-TG>20 mm的16例患者,同时行胫骨结节内移截骨。结果 27例获随访,随访时间40～67个月,平均45.5个月。患者术后均无髌骨再脱位,也无髌骨错动或半脱位。0°位和屈膝30°位髌骨外推试验和外推恐惧试验均为阴性。术后1年患者膝关节屈伸活动度均恢复正常,能够完全下蹲。末次随访时Kujala评分、Lysholm评分分别为(94.10±7.59)、(95.44±6.25)分,与术前比较差异均有统计学意义(P<0.05);Tegner评分为(4.33±1.00)分,与术前比较差异无统计学意义(t=1.302,P=0.213)。术前TT-TG>20 mm的患者末次随访时TT-TG为(16.88±5.92)mm,与术前(23.38±3.70)mm比较差异有统计学意义(t=2.822,P=0.026)。结论 MPFL重建治疗复发性髌骨脱位能够明显改善髌骨稳定性,且术后膝关节功能评分和运动等级评分均较术前明显改善。     

Multilevel Schwab grade II osteotomies for sagittal plane correction in the management of adult spinal deformity

Background Context

Prior reports have compared posterior column osteotomies with pedicle subtraction osteotomies in terms of utility for correcting fixed sagittal imbalance in adolescent patients with deformity. No prior reports have described the use of multilevel Smith-Petersen Osteotomies (SPOs) alone for surgical correction in the adult spinal deformity (ASD) population.

A novel anterior decompression technique (vertebral body sliding osteotomy) for ossification of posterior longitudinal ligament of the cervical spine

Background Context

Conventional anterior decompression surgery for cervical myelopathy, including anterior corpectomy and fusion, is technically demanding and is known to be associated with a higher incidence of surgery-related complications, including cerebrospinal fluid (CSF) leakage, neurologic deterioration, and graft failure compared with posterior surgery.

High tibial osteotomy combined with anterior displacement of the tibial tubercle for osteoarthritis of the knee

Summary Eighty-nine knees with medial tibiofemoral and patellofemoral osteoarthritis were treated by high tibial osteotomy between 1972 and 1978, and 71 were followed up for at least 5 years, the average being 6 years and 9 months. There was no significant loss of motion as recorded before and after operation. In most patients pain decreased or disappeared, and walking ability was regained. Evaluation using the Japanese rating system showed that there were Good and Fair results in 86% of the cases. The average tibio-femoral angle in the Good group was 169±5°. The angles in the Poor group varied over a wide range. There were serious complications such as nonunion, malunion and infection in a few cases. In Group 1 (30 knees) high tibial osteotomy alone was performed. In Group 2 (41 knees) there were associated osteoarthritic changes in the patellofemoral joint and a high tibial osteotomy was combined with anterior displacement of the tibial tubercle (ventralisation). In comparison, Group 2 had better results with regard to both clinical and radiological evaluation.Read at the 16th Congress of the Societe Internationale de Chirurgie Orthopedique et de Traumatologie, London, England, 5th October, 1984     

后路全脊椎截骨术治疗先天性脊柱侧后凸畸形

目的评价后路全脊椎截骨术治疗先天性脊柱侧后凸畸形的临床效果。方法 2007年8月至2009年12月,采用后路全脊椎截骨术治疗先天性脊柱侧后凸畸形病例21例,男7例,女14例;年龄7～32岁,平均16.3岁;胸段19例,腰段2例;伴发脊髓纵裂7例,脊髓空洞1例,不全瘫3例。所有病例均行后路一期全脊椎截骨、矫形植骨融合固定术。测量术前、术后及随访时站立位全脊柱正侧位X线片,记录冠状面和矢状面Cobb角、顶椎偏移;记录术中出血量、手术时间及围手术期并发症。结果所有患者切口均一期愈合,随访时间16～38个月,平均22.4个月。本组病例手术时间平均为694.5min,术中出血量平均2429ml,冠状面Cobb角由82.9°矫正到36.0°,平均矫形率56.6%,矢状Cobb角由82.5°矫正到39.8°,平均矫形率51.8%,顶椎偏移由27.1mm矫正到11.1mm,矫正率59.0%。1例术后神经诱发电位示右胫后神经SEP降低,2周后恢复,无其他神经系统并发症,椎体间植骨病例随访时均获得融合,无内固定松动、断裂等并发症。结论后路全脊椎截骨椎体切除可直接去除致畸原因,在冠状面和矢状面上均可获得良好的矫形,并可获360°减压,是目前治疗先天性脊柱侧后凸畸形较为有效的方法。
