【摘要】 目的 比较胫骨平台骨折术后辅助与不辅助持续被动运动（continuous passive motion，CPM）的临床疗效。 方法 对2008年6月-2009年6月86例行手术治疗的闭合性、无合并损伤的胫骨平台骨折患者进行回顾性分析。根据是否辅助CPM分为CPM组27例和非CPM组（对照组）59例。对两组患者的伤口愈合情况，膝关节屈曲、伸直角度，以及膝关节功能恢复情况进行比较。 结果 两组伤口甲级愈合率差异无统计学意义（P=0.566）。在术后2周和6周，CPM组患者的膝关节屈曲角度明显大于对照组（Plt;0.001），但在术后3个月和12个月，两组的差异无统计学意义（P=0.219，P=0.512）。在术后2、6周，3、12个月，CPM组和对照组患者的膝关节伸直角度差异无统计学意义。在术后12个月的Rasmussen膝关节功能评分方面，CPM组和对照组的差异无统计学意义。 结论 胫骨平台骨折术后辅助CPM能早期提升膝关节屈曲角度，但并不能提高远期的膝关节活动度和最终的膝关节功能。【Abstract】 Objective To compare the therapeutic effect of continuous passive motion (CPM) treatment after tibial plateau fractures operation. Methods From June 2008 to June 2009, 86 patients were treated due to closed tibial plateau fractures without combined injuries. The patients were treated with (27 patients, CPM group) and without (59 patients, control group) CPM. The wound healing rates, range of motion and the knee function were compared between the two groups. Results There was no significant difference between the two groups in wound healing rates (P=0.566). Two and six weeks after the operation, there were significant differences between the two groups in flexion degree (Plt;0.001); three and 12 months after the operation, there were no significant differences between the two groups (P=0.219, P=0.512). At the 2nd and 6th week, 3rd and 12th month postoperatively, there were no significant differences between the groups in extension degree. Twelve months after the operation, there were no significant differences between the groups in functional recovery of the knee. Conclusion CPM in the post-operative treatment of tibial plateau fractures is effective increasing knee flexion in the early stage, but is not effective increasing range of motion or knee function in a long term.
Objective To compare differences in the cl inical outcomes between percutaneous pinning with plaster spl int and open reduction and pull ing out wire in the treatment of mallet fingers. Methods From December 2002 to September 2007, 72 patients with mallet fingers were treated. They were divided into two groups: group A and group B. In group A, 38 patients were treated by open reduction and pull ing out wire, 34 males and 4 females, aged (26.0 ± 8.5) years. Among them, 2 patients were injured in the index finger, 11 in the middle finger, 18 in the ring finger and 7 in the l ittle finger. Thirtythreepatients suffered from sports injuries, 5 from fall ing wounds. The average time between the injury and the surgery was(6.1 ± 3.1) days. In group B, 34 patients were treated by percutaneous pinning with plaster spl int, 26 males and 8 females, aged (28.1 ± 10.7) years. Among them, 1 patient was injured in the index finger, 9 in the middle finger, 15 in the ring finger and 9 in the l ittle finger. Thirty-one patients suffered from sports injuries, 3 from fall ing wounds. The average time between the injury and the surgery was (6.3 ± 3.6) days. All the fingers had typical mallet malformation, and X-ray films showed avulsed fractures of distal-segment phalanxes at the dorsal basilar part. Results The operation time was (61.8 ± 12.8) minutes in group A and (7.0 ± 2.6) minutes in group B. All patients in both groups were followed up for 6-24 months (11.9 months on average in group A and 13.2 months in group B). In group A, apart from 3 patients who had flap necrosis and infection, all the other patients obtained heal ing by first intention. One patient had palmar skin ulcer at 6 days after the operation and healed after proper treatment. Thirty-six patients gained bone union at (47.6 ± 8.7) days postoperatively and 2 patients had pseudarthrosis, which improved after reconstruction of the extensor tendon attachment point. According to the total active movement (TAM) functional assessment system, 10 cases were e cellent, 18 good, 8 fair and 2 poor, with the choiceness rate of 73.7%. In group B, all incisions obtained heal ing by first intention without pin-track infection, flap necrosis and migration of the pins and gained bone union at (27.7 ± 3.9) days after the operation. According to the TAM functional assessment system, 19 cases were excellent, 13 good and 2 fair, with the choiceness rate of 94.1%. There were significant differences between the two groups in operation time, compl ications, heal ing time and choiceness rate (P lt; 0.05). Conclusion Percutaneous pinning with plaster spl int is simple in operation and has smaller incisions and fewer compl ications compared with open reduction and pull ing out wire, andproves to be a useful way in the treatment of mallet fingers.
Objective To study the effect of internal fixation with absorbable intramedullary nail on the treatment of phalange fractures in replantation of severed finger. Methods From September 2001 to October 2003, 28 cases with industrial severed finger (21 males and 7 females, with the age of 18-35 years) were replanted within 1-6 hours. The severed locations were index fingers in 11 cases, middle fingers in 8 cases, ring fingers in 6 cases, little fingers in 3 cases. All cases of phalange fractures were fixed by absorbable intramedullary nails of poly-DL-lactic acid(PDLLA) that combined with chitosan. Out of the 28 cases, 15 cases were with proximal phalange, 11 cases were with middle phalange, 2 cases were with distal phalange. The bone marrow cavity of the phalanges were dilated, then the intramedullary nail was inserted with suitable diameter and length to fix the fracture. Postoperatively resin bandage was applied for 3-4 weeks.Results All the 28 patients survived the performance and postoperative follow-up ranged from 3 to 10 months(4 months in average). Rejection was observed in one case 3 weeks after operation, bone unions were obtained in other cases. According to the Chinese Medical Association’s evaluation standard for replantation of amputated finger, 18 fingers resulted in excellence, 9 fingers in good function and 1 with unsatisfactory function. The excellent and good rate was 96.4%. Conclusion Internal fixation with absorbable intramedullary nail of PDLLA combined with chitosan proves to be effective in the replantation of severed finger.
Objective To determine the efficacy and complication rate of intramedullary nailing versus compression plate in the treatment of adult humeral shaft fracture. Methods We searched the specialized trials register of The Cochrane Collaboration’s Bone, Joint and Muscle Trauma Group, The Cochrane Library (including CENTRAL), MEDLINE (1966 to 2006), EMbase (1980 to 2006), PubMed (1966 to 2006), NRR (http://www.update-software.com/National/), CCT (http://www.controlled-trials.com) and CBMdisc (1979 to July 2006). We also handsearched some Chinese orthopedic journals. Data were extracted and evaluated by two reviewers independently. Randomize controlled trials comparing intramedullary nailing versus compression plate for humeral shaft fracture in adults were included and the quality of these trials was critically assessed. Data analyses were done using The Cochrane Collaboration’s RevMan 4.2.8. Results Three randomize controlled trials involving 215 patients were included. The meta-analysis showed that intramedullary nailing may increase the re-operation rate (OR=2.68, 95%CI 1.19 to 6.04, P=0.02), pain in the shoulder (OR=13.02, 95%CI 2.23 to 75.95, P=0.004), and the rate of decreased range of motion of the shoulder (OR=18.60, 95%CI 1.01 to 341.83, P=0.05). The rates of no union, infection and iatrogenic radial nerve injury were comparable between intramedullary nailing and compression plate. Meta-analysis was not conducted for the time of union, because the relevant data were not available for the included trials. Conclusions Further well-designed and large-scale randomize controlled trials are required to determine the effects of intramedullary nailing and compression plate on these outcomes, because the trials available for this systematic review are too few and too small.
Objective To determine the effect of non-reamed versus reamed intramedullary nailing for tibial fractures in adults on the rates of nonunion, the rates of implant failure, the rates of infection, the incidence of compartment syndrome, the rates of malunion, and the time of union. Methods We searched MEDLINE （1966 -July, 2005）, EMBASE （1974 -July, 2005 ）, The Cochrane Library （Issue 2, 2005 ）and CBMdisc （1979 -July, 2005 ）, and handsearched the relevant Chinese and English orthopedic journals. Randomized controlled trials and Clinical controlled trials of nonreamed versus reamed intramedullary nailing for tibial fractures in adults were included. The quality of trials was critically assessed. RevMan 4.2.7 software was used for data analysis. Results Four RCTs and one CCT of non-reamed versus reamed intramedullary nailing for tibial fractures in adults were included. The results of meta-analysis showed that nonreamed intramedullary nailing for tibial fractures in adult increased the rates of nonunion （RR 1.87, 95% CI 1.20 to 2. 91, P =0. 006）, implant failure （RR 2.23, 95% CI 1.49 to 3.34, P〈0. 000 1 ） and the time to union （WMD 9.00, 95% CI 3.19 to 14.81, P =0. 002）. Conclusions Compared with reamed intramedullary nailing for tibial fractures in adults, non-reamed intramedullary nailing increases the rates of nonunion and implant failure is common. There is no statistical difference in the rates of post operative infection, the rates of malunited fracture and the incidence of compartment syndrome between the two groups. However, further studies are needed to determine the effects of reamed and non-reamed intramedullary nailing on these outcomes, expecially when patient has severe open fractures （Gustilo Grade Ⅲ C）and multiple injuries.
Objective To evaluate the effectiveness of reamed versus nonreamed intramedullary nailing for femoral fractures. Methods Randomized controlled trials (RCTs) and clinical controlled trials (CCTs) were identified from MEDLINE (1966-2004.5), EMBASE (1966-2004.5), Cochrane Library (Issue 2, 2004), Cochrane Musculoskeletal Injuries Group Database (2004.5), and CBM disc (1979-2004.5). We handsearched Chinese Journal of Orthopaedy (from establishment to May 2004) and Orthopaedic Journal of China (from establishment to May 2004) . RCTs and CCTs were included. Data were extracted by two reviewers with designed extraction form. RevMan 4.2.3 software was used for data analysis. Results Five RCTs and two CCTs were included. The combined results of meta-analysis showed that reamed intramedullary nailing for femoral fractures can reduce the rate of nonunion (RR=0.38, 95%CI 0.17 to 0.83, P=0.01) and the rate of implant failure (RR=0.42, 95%CI 0.20 to 0.89, P=0.02). Conclusions Compared with nonreamed intramedullary nailing for femoral fractures, reamed intramedullary nailing can reduce the rates of nonunion and implant failure. However, the relation between reaming or pulmonary complications, the time of union, infection, malunion, operative time, and blood loss needs further study.

Objective To summarize the general concept of lateral wall, the causes of lateral wall injury, and surgical strategies in order to improve the understanding of lateral wall and reduce the complications of operation. Methods The related literature on lateral wall was extensively reviewed, summarized, and analyzed. Results The superior extent of the lateral wall is vastus lateralis ridge and the inferior extent is the intersection between the lateral femoral cortex and a line drawn at a tangent to the inferior femoral neck. The integrity of the lateral wall is important to prevent the failure of fixation and reoperation of intertrochanteric fractures. The main causes of injury are that there is no suitable typing criteria as a guide, the fracture pattern shown by X-ray does not match with the actual situation of the fracture, the type of fracture is special, and the operation is improper. The main treatment is to reconstruct the lateral wall and choose different reconstruction methods according to different fracture patterns. Conclusion The lateral wall is very important for the treatment of intertrochanteric fracture. Lateral wall fracture should be internal fixation in order to minimize the risk of reoperation.
