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 , CCT 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 analyze the causes and managing methods of long bone fracture nonunion after allogeneic bone transplantation. Methods From December 1995 to December 2000, 43 cases of postoperative nonunion of long bone fracture were treated. These cases included 31 males and 12 females at the age of 19-57 years (40 years on average). The locations were femur in 11 cases, tibia in 21 cases, humerus in 8 cases and forearm in 3 cases. Bone nonunionafter allogeneic bone transplantation was caused by extensive soft tissue contusion and poor cover around bone fractue site in 6 cases, by incomplete debridement in 8 cases of osteomyel itis (including 6 without continual lavage and 4 only skin flap transfer), by secondary infection of wounds in 3 cases, by severe primary injury or secondary scar covering bone in 12 cases, instable internal fixation in 7 cases, and by earl ier weight bearing in 7 cases. Accroding to Weber classification, there were 4 cases of hypertrophic type and 39 cases of atrophic type. Basing on the type of nonunion, the methods such as refixation, bone retransplantation and transferring tissue flap were chosen to manage the cases. Results Incision healed by first intention in 37 cases, superficial infection occurred and cured after 2 weeks of dressing change in 5 cases, and sinus formed and cured after 2 months of dressing change and drainage in 1 case. All transferring tissue flap survived, and partial necrosis occurred at flap edge in 4 cases and cured after dressing change. All patients were followed up for 38-91 months with an average of 54.6 months. All the nonunion cases achieved bone union 5-11 months with an average of 7.6 months. But low extreme shorten monstrosity occured in 4 cases, malunion in 2 cases, functional l imitation near joints in 7 cases, and rotational l imitation of forearm in 1 case. Conclusion Fracture nonunion after allogeneic bone transplantation mainly shows atrophic type with overall or partial absorption of the allograft bone. The preconditions to guarantee fracture nonunion heal ing include stabil ity of fracture fixation, using transferring tissue flaps, controll ing infection, and adequate bone transplantion.

【摘要】 目的 比較脛骨平臺骨折術后輔助與不輔助持續被動運動（continuous passive motion，CPM）的臨床療效。 方法 對2008年6月-2009年6月86例行手術治療的閉合性、無合并損傷的脛骨平臺骨折患者進行回顧性分析。根據是否輔助CPM分為CPM組27例和非CPM組（對照組）59例。對兩組患者的傷口愈合情況，膝關節屈曲、伸直角度，以及膝關節功能恢復情況進行比較。 結果 兩組傷口甲級愈合率差異無統計學意義（P=0.566）。在術后2周和6周，CPM組患者的膝關節屈曲角度明顯大于對照組（Plt;0.001），但在術后3個月和12個月，兩組的差異無統計學意義（P=0.219，P=0.512）。在術后2、6周，3、12個月，CPM組和對照組患者的膝關節伸直角度差異無統計學意義。在術后12個月的Rasmussen膝關節功能評分方面，CPM組和對照組的差異無統計學意義。 結論 脛骨平臺骨折術后輔助CPM能早期提升膝關節屈曲角度，但并不能提高遠期的膝關節活動度和最終的膝關節功能。【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 review the clinical characteristics of patients with traumatic spinopelvic dissociation (SPD) and explore the diagnostic and therapeutic methods. Methods A clinical data of 22 patients with SPD who underwent surgical treatment between March 2019 and August 2024 was retrospectively analyzed. There were 13 males and 9 females, with an average age of 35.5 years (range, 14-61 years). The causes of injury included falling from height in 16 cases, traffic accidents in 5 cases, and compression injury in 1 case. Sacral fractures were classified based on morphology into “U” type (9 cases), “H” type (7 cases), “T” type (4 cases), and “λ” type (2 cases). According to the Roy-Camille classification, there were 4 cases of type Ⅰ, 12 cases of type Ⅱ, 2 cases of type Ⅲ, and 4 cases of type Ⅳ. The Cobb angle was (35.7± 22.0)°. Sixteen patients were accompanied by lumbosacral trunk and cauda equina nerve injury, which was classified as grade Ⅱ in 5 cases, grade Ⅲ in 5 cases, and grade Ⅳ in 6 cases according to the Gibbons grading. The time from injury to operation was 2-17 days (mean, 5.7 days). Based on the type of sacral fracture and sacral nerve injury, 6 cases were treated with closed reduction and minimally invasive percutaneous sacroiliac screw fixation, 16 cases were treated with open reduction and lumbar iliac fixation (8 cases)/triangular fixation (8 cases). Among them, 11 patients with severe fracture displacement and kyphotic deformity leading to sacral canal stenosis or bony impingement within the sacral foramen underwent laminectomy and sacral nerve decompression. X-ray films and CT were reviewed during followed-up. The Matta score was used to evaluate the quality of fracture reduction. At last follow-up, the Majeed score was used to assess the functional recovery, and the Gibbons grading was used to evaluate the nerve function. Results All operations were successfully completed. All patients were followed up 8-64 months (mean, 20.4 months). Two patients developed deep vein thrombosis of the lower limbs, 2 had incision infections, and 1 developed a sacral pressure ulcer; no other complications occurred. Radiological examination showed that the Cobb angle was (12.0±6.8)°, which was significantly different from the preoperative one (t=6.000, P<0.001). The Cobb angle in 16 patients who underwent open reduction was (14.9±5.5)°, which was significantly different from the preoperative one [(46.8±13.9)° ] (t=8.684, P<0.001). According to the Matta scoring criteria, the quality of fracture reduction was rated as excellent in 8 cases, good in 7 cases, fair in 5 cases, and poor in 2 cases, with an excellent and good rate of 68.2%. Bone callus formation was observed at the fracture site in all patients at 12 weeks after operation, and bony union achieved in all cases at last follow-up, with a healing time ranging from 12 to 36 weeks (mean, 17.6 weeks). At last follow-up, the Majeed score was rated as excellent in 7 cases, good in 10 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 77.3%. One patient experienced a unilateral iliac screw breakage at 12 months after operation, but the fracture had already healed, and there was no loss of reduction. Among the 16 patients with preoperative sacral nerve injury, 11 cases showed improvement in nerve function (6 cases) or recovery (5 cases). Conclusion SPD with low incidence, multiple associated injuries, and high incidence of sacral nerve injury, requires timely decompression of the sacral canal for symptomatic sacral nerve compression, fractures reduction, deformities correction, and stable fixation.
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 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 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 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.
