BACKGROUND: Posterior hip dislocation combined with femoral head fractures easily induced femoral head necrosis, ectopic ossification, osteoarthritis and deep vein thrombosis. Different therapeutic methods should be utilized according to the type of fracture. OBJECTIVE: To investigate the factors affecting the therapeutic effects and complications following surgery of posterior hip dislocation combined with femoral head fractures. METHODS: Twenty-eight patients, who had been diagnosed as posterior hip dislocation combined with femoral head fractures in the 101 Hospital of Chinese PLA from September 2004 to May 2010, were enrolled in this study.According to Pipkin typing, operative approach and the time from injury to surgery, therapeutic effects were evaluated using radiographs and the recovery conditions of hip function(Epstein method), and the occurrence of complications was recorded. RESULTS AND CONCLUSION: A total of 28 patients were followed up from 1 to 5 years, averagely 2.8 years. Using the Epstein method, there were excellent in 6 cases, good in 12 cases, average in 7 cases, and poor in 3 cases, with an excellent and good rate of 64%. The therapeutic effects in patients with Pipkin I and II were good,with excellent and good rates of 100% and 78%, respectively. Moreover, the complications were less, with a rate of 17% and 22%, respectively. The therapeutic effects of patients with Pipkin III and IV were poor, especially, Pipkin IV patients, whose excellent and good rate was only 20% and the incidence of complications was 80%. No significant difference in the incidence of complications was detected in patients undergoing Smith-Peterson anterior approach and K-L posterior approach(P > 0.05). No significant difference in the incidence of complications was detectable among patients from three groups(the time from fracture to operation < 12 hours, 12-48 hours, and > 48 hours)(P > 0.05). Results indicated that the choice of treatment method should bedetermined by the type of fracture. The prognosis depends on the patient’s age, time of treatment, types of fracture and dislocation, methods of treatment and related measures of prevention of complications. © 2014, Journal of Clinical Rehabilitative Tissue Engineering Research.

BACKGROUND: Allogeneic tissue transplantation has become a choice of ligament graft and reconstruction, and allogenic bone-patellar tendon-bone graft is a method for lateral collateral ligament reconstruction. OBJECTIVE: To investigate the clinical effect of allogenic bone-patellar tendon-bone graft for chronic lateral collateral ligament injury. METHODS: From April 2008 to December 2009, 11 cases of III degree chronic lateral collateral ligament injury were selected and treated with lateral collateral ligament reconstruction by allogenic bone-patellar tendon-bone graft. RESULTS AND CONCLUSION: All patients were followed-up for 12-15 months. The wound healed by first intention. The movement ranges of the knee were significantly increased preoperatively (P < 0.05). The Lysholm scroe at the last follow-up was significantly increased as compared with preoperatively. Preoperative varus stress radiographs demonstrated the knee lateral joint space increase of 8 to 20 (12.9±3.5) mm in average compared with the contralateral, the knee lateral joint space was 2-3 (1.0±1.9) mm at 6 months postoperatively, and there was a significant difference (P < 0.05), and there was no significant difference when compared with the healthy side (P > 0.05). Reconstruction of the lateral collateral ligament with allogenic bone-patellar tendon-bone graft is a viable option to treat chronic lateral collateral ligament tears, and can restore normal varus stability, and plays a protect effect on other soft fissue repair.

BACKGROUND: Traditional dynamic hip screw (DHS), proximal femur nail anti-rotation (PFNA) and anatomic proximal femoral locking plate (APFLP) are used in internal fixation of intertrochanteric fractures, but now which one is best method for the treatment of intertrochanteric fractures is still controversial. OBJECTIVE: To investigate the clinical efficacy of the DHS, PFNA and APFLP for the treatment of the intertrochanteric fractures in old people. METHODS: Totally 159 elderly patients with intertrochanteric fractures were retrospectively analyzed. Difference of the DHS, PFNA and APFLP for the treatment of the intertrochanteric fractures was compared. RESULTS AND CONCLUSION: 1Harris hip function score in the PFNA group was better than that in the APFLP group (P < 0.05) which was superior to DHS group (P < 0.05) at 1 week, 6 months and 1 year after surgery. X-ray of fracture healing in the PFNA group was better than that in the APFLP group (P < 0.05) which was superior to the DHS group (P < 0.05) at 3, 6, 12 months after surgery. It is indicated that the PFNA for the treatment of intertrochanteric fractures has many advantages in less damage, stronger fixation, simpler operation, higher fracture healing, shorter healing time, better functional recovery and so on. It is the ideal fixation for intertrochanteric fractures in old people.

BACKGROUND: Now the studies on hook plate are mainly the curative effect and complications after internal fixation, but studies about symptoms and corresponding imaging changes after removing internal fixation are rarely. OBJECTIVE: To discuss the symptoms and imaging changes after removing hook plate and the necessity of removing hook plate. METHODS: Totally of 87 patients with the hook plate for the treatment of Neer II type of distal clavicle fractures and Tossy III type acromioclavicular joint dislocation were selected from Department of Orthopedics, the 101 Hospital of Chinese PLA between January 2009 and January 2011. There were 54 males and 33 females, aged 20-61years old with the average age of 39.8 years. All the patients were taken conventional X-ray after the hook plate removal. Shoulder joint function was tested by using Constant-Murley score system before and after the hook plate removal. RESULTS AND CONCLUSION: All the 87 patients were followed-up for 8 to 18 months. The hook plate was removed at about 12 weeks. Wound healing was well and without infection, fixation fracture and hook loosening. Constant-Murley score after the hook plate removal was significantly increased as compared with that before removing the plate (P < 0.001), except 8 cases were opposite which corresponding X-ray films were mainly represented bone absorption, acromioclavicular arthritis and acromion degeneration. The X-ray films explained why the score in the eight cases was opposite and this could be regarded as the diagnostic criteria to guide clinical treatment after removing fixation. It is recommended that the fixation should be timely removed after the shoulder ligaments (acromioclavicular ligament coracoclavicular ligament) healing.

Background: Currently thoracolumbar fixation techniques have its advantages and disadvantages, it is necessary to explore a new internal fixation to fix the spine effectively and conveniently. Objective: To establish thoracolumbar (T12-L2) three-dimensional finite element model and observe the effect of anteroposterior integration fixation by posterolateral nail-stick system on thoracolumbar stability. Methods: Based on the CT scan data of normal human T12-L2 segments, we used Geomagic 11.0, Ug 7.0, Hypermesh 10.0, Abaqus 6.9.1 software to establish a three-dimensional finite element model of T12-L2 segments. Subsequently we established nail-stick system posterior fixation, anterior fixation, posterolateral anteroposterior integration fixation model. T12 segment was given 500 N preload and 7.5 N·m torque, to simulate thoracolumbar flexion, extension, lateral bending and rotation. The average rigidity of fixed segments under different conditions were observed. Results and Conclusion: Three fixation models showed a higher average rigidity than normal model under different conditions. The average rigidity in anteroposterior integration fixation by posterolateral nail-stick system was increased by 13%, 28%, 11%, 17% and 9%, compared with simple posterior fixation under the conditions such as anterior flexion, lateral bending and lateral rotation, respectively. Under the posterior extension, the average rigidity was reduced by 6% than the posterior fixation. Compared with the anterior fixation, the average rigidity in anteroposterior integration fixation by posterolateral nail-stick system was reduced by 15%, 10%, and 14% under the conditions of anterior flexion and lateral bending. While the average rigidity was higher than anterior flexion under the posterior extension and lateral rotation, increasing 5%, 12% and 2%. The anteroposterior integration fixation by posterolateral nail-stick system can improve the stability of fixed segments, and the stability is higher than anterior fixation at posterior extension and lateral rotation, while higher than posterior fixation in anterior flexion, lateral bending and lateral rotation. So it is a potential fixation method. © 2014, Journal of Clinical Rehabilitative Tissue Engineering Research. All rights reserved.

BACKGROUND: Low concentration of nicotine promotes the angiogenesis and facilitates the healing of skin wounds. However, the role of low concentration of nicotine on the repair of maxillofacial soft tissue trauma especially oral mucosa still remains unclear OBJECTIVE: To evaluate the effect of low concentration of nicotine on mucosa defect repair of rat hard palate. METHODS: A circular soft tissue defect at 3 mm diameter was produced in the centre of hard palate of 65 Wistar rats. After the operation, animals were randomly divided into low concentration of nicotine with gel group, gel group and control group. Rats were sacrificed at 3, 7, 10 and 14 days post-surgery. The wound healing was detected with hematoxylin-eosin staining and the difference of wound healing in different groups was compared with gross observation and image measurement. RESULTS AND CONCLUSION: There was no significant difference in the wound healing in different groups on day 3 post-surgery. On days 7 and 10, the group of low concentrations of nicotine with gel was faster than gel group and control group (P < 0. 05); the wounds were completely healed on day 14, with no significant difference among the groups. Low concentrations of nicotine may promote the mucosa defects repair of rat hard palate.

Background: A lot of reports focus on the treatment of acromioclavicular joint dislocations with many differences on the methods and implants. The methods for treatment of the acromioclavicular joint dislocations which used more often in clinic are acromioclavicular fixation and coracoclavicular fixation. There exists great controversy on which method is better. Objective: To compare the curative effects between acromioclavicular fixation and coracoclavicular fixation for acromioclavicular joint dislocations through Meta-analysis. Methods: Related randomized controlled trials on acromioclavicular fixation and coracoclavicular fixation for acromioclavicular joint dislocations were searched in PubMed database (1950-01/2011-10), EMBASE database (1966-01/2011-10), CNKI database (1979-01/2011-10), Wanfang database (1982-01/2011-10) and VIP database (1989-01/2011-10). The articles were collected according to the inclusion criteria and then compared. Heterogeneity analysis and Meta-analysis were performed using RevMan5.0 software, and then the forest graph was made. Results and Conclusion: Nine articles involving 473 patients and 473 acromioclavicular joints were accepted in our Meta-analysis. There were no significant differences in curative effect score, strength of upper limbs, shoulder movement, re-dislocations rate between acromioclavicular fixation and coracoclavicular fixation. Therefore, the clinical treatment of acromioclavicular joint dislocation can not only use the acromioclavicular fixed or coracoclavicular fixation, doctors should choose the best method according to the patients' condition, hospital conditions and the surgery proficiency of the doctor.

BACKGROUND: Doctors often use autoallergic hamstring double-bundle and single-bundle for the reconstruction of anterior cruciate ligament, but there is a controversy on which method is better. OBJECTIVE: To evaluate the clinical outcome of double-bundle versus single-bundle autoallergic hamstring for the reconstruction of anterior cruciate ligament. METHODS: Randomized controlled trials about comparing double-bundle with single-bundle autoallergic hamstring for the reconstruction of anterior cruciate ligament were collected from PubMed database, Cochrane library, Springerlink database, CNKI database and CBM database. The Jadad's scale was used to assess the methodological quality of the randomized controlled trials and Cochrane collaboration's RevMan 5.0 software was used to perform the Meta analysis. RESULTS AND CONCLUSION: Fifteen randomized controlled trials totally 1 008 patients met the inclusion criteria and included. Meta-analysis results showed that there was statistical difference of postoperative KT-1000 or KT-2000 arthrometer mesurement between double-bundle and single-bundle reconstruction [weighted mean difference (WMD)=-0.51, 95% confidence interval (CI) (-0.74, -0.28), P < 0.000 1], there was significant difference of the negative pivot-shift testing [relative risk (RR)=1.27, 95%CI(1.11, 1.45), P=0.000 3], as well as the postoperative Lysholm scores [WMD=-2.10, 95%CI(-3.65, -0.55), P=0.008]. But there was no statistical differences of IKDC final score [RR=1.04, 95%CI(0.99, 1.06), P=0.10]. The double-bundle autoallergic hamstring is superior to single-bundle for anterior cruciate ligament reconstruction on recovering stability of knee joint, but they are similar in recovering the functions of knee joint.

BACKGROUND: At present, there is not a unified standard about when to start ambulation after lumbar diskectomy. In the present experiment, we guided functional exercises of patients after lumbar diskectomy based on early biomechanical changes. OBJECTIVE: To explore the effects of fatigue load on lumbar stability after lumbar diskectomy. METHODS: Twelve functional spinal units were taken from 3 fresh porcine spines and divided into A group, B group and C group randomly. Fatigue load test was performed in all cases with different cycle load pressures (500-1 000 N, 500-2 000 N, 500-3 000 N) after unilateral lumbar diskectomy. RESULTS AND CONCLUSION: There was no significant difference between A group and B group in disc height and stiffness (P > 0. 05), but the increased strain showed significant difference (P < 0. 05); Disc height and stiffness in B group and C group was reduced, strain was increased, and all these differences were significant (P < 0. 01). Change ranges of disc height, strain and stiffness in the three groups were increased with the increase of the load pressure after cyclic tensile test (P < 0. 05). The results showed that a bigger fatigue load can damage lumbar stability after lumbar diskectomy.

BACKGROUND: It is an issue of concern to increase the stability of micro-implants, reduce the failure rate, and correctly use micro-implant anchorage. OBJECTIVE: To observe the influence on the success rate of orthodontic micro-implant using two kinds of positioning methods. METHODS: Thirty-eight patients who required implant anchorage were evaluated. All the implants were imbedded in the alveolar bone between the maxillary second premolar and first molar. One side of each patient was randomly selected to imbed micro-implant by using X-ray film, as the A group; the other side using three-dimensional plate, as the B group. RESULTS AND CONCLUSION: After 5-7 months of clinical use of implant anchorage, 29 micro-implants of the A group were stable, 9 loosened, AND the success rate was 76.3%; 36 micro-implants of the B group were stable, 2 loosened, and the success rate was 94.7%. The success rates of two groups were significantly different (P < 0.05). Compared with the traditional positioning method, the three-dimensional guide of orthodontic micro-implant may achieve the best implant site, thus effectively reducing implant anchorage failure rate.
