Objective To investigate the improved reduction technique for depression fractures of the lateral tibial plateau and its effectiveness. Methods Between January 2008 and December 2010, 48 patients (48 knees) with depression fractures of the lateral tibial plateau (Schatzker II or III fractures) were treated. There were 32 males and 16 females with an average age of 45.8 years (range, 16-79 years). All fractures were fresh closed fractures, which were caused by traffic accident in 27 cases, by falling from height in 5 cases, by crushing in 8 cases, and by sustained falls in 8 cases. According to Schatzker classification, 29 cases were classified as type II and 19 cases as type III. The lateral cortex was cut off to expose the depression and compacted cancellous bone was elevated to reset the articular surface. After reduction, autologous iliac bone graft and locking plate internal fixation were used. Results Healing of incision by first intention was achieved in all patients, and no complication occurred. All patients were followed up 1.7 years on average (range, 1-3 years). At last follow-up, the knee extension was ( — 0.5 ± 0.3)°, and the knee flexion was (136.9 ± 8.8)°. X-ray films showed that the fracture healing time was 52 weeks and no breakage of internal fixation occurred. According to Rasmussen clinical score, the results were excellent in 35 cases, good in 10 cases, and fair in 3 cases. According to Rasmussen radiographical score, the results were excellent in 41 cases, good in 7 cases; there were 41 excellent scores and 7 good scores of articular reduction; all gained good recovery of coronal and sagittal alignment and condylar width. The articular surface collapse was (1.0 ± 0.7) mm at immediate postoperatively and (1.2 ± 0.7) mm at last follow-up, showing no significant difference (t= — 1.42, P=0.20), but significant differences were found when compared with that at preoperation [(12.2 ± 8.0) mm, P lt; 0.05]. Conclusion This improved technique can provide a satisfactory effectiveness of fracture reduction and can avoid loss of reduction. The short-term effectiveness is good, but futher follow-up is necessary to determine the long-term results.
To discuss the effect of dexamethasone in preventing fat embol ism syndrome (FES) in cemented hi p arthroplasty patients. Methods Forty patients scheduled for unilateral cemented hi p arthroplasty between January 2008 and December 2009 were randomly divided into trial group (n=20) and control group (n=20). In trial group, there were 6 males and 14 females with an average age of 73.2 years (range, 54-95 years), including 4 cases of osteoarthritis, 3 cases ofavascular necrosis of femoral head, and 13 cases of femoral neck fracture; the disease duration was 4 days to 6 years (median, 0.8 year). In control group, there were 10 males and 10 females with an average age of 71.9 years (range, 59-91 years), including 2 cases of osteoarthritis, 3 cases of avascular necrosis of femoral head, and 15 cases of femoral neck fracture; the disease duration was 3 days to 5 years (median, 0.6 year). There was no significant difference in gender, age, or disease duration (P gt; 0.05) between 2 groups. Cemented total or bipolar hip arthroplasty (with the same brand of cement and prosthesis) in 2 groups were performed by a group of surgeons. The patients were given intravenously injected with dexamethasone (20 mg) in trial group before 1 hour of cement injection and intravenously injected with normal sal ine (2 mL) in control group. Amount of 5 mL vein blood were withdrawn before surgery, after 4, 8, and 24 hours of cement injection to test the number and average diameter of fat droplets. According to Gurd diagnosis standard, related FES symptoms and signs were inspected. Results Primary heal ing of incision was achieved in all cases of 2 groups. According to Gurd standard of diagnosis, no FES occurred in each group at 2 weeks postoperatively; deep venous thrombosis occurred in 2 cases (10%) of trial group and in 5 cases (25%) of control group, showing significant difference (P lt; 0.05). The number and diameter of fat droplets in trial group were significantly lower than those in control group at 4, 8, and 24 hours of cement injection (P lt; 0.01). All cases were followed up 7.4 months on average (range, 3-13 months). The postoperative Harris score was 89.5 ± 6.1 in trial group and 87.9 ± 8.3 in control group, showing no significant difference (P gt; 0.05). No loosening occurred during follow-up period. Conclusion Intravenous injection withdexamethasone can effectively reduce the number and diameter of venous fat droplets in cemented hip arthroplasty, which can decrease the risk of postoperative FES.
【Abstract】 Objective To discuss the techniques and advantages of closed reduction and intramedullary nail ing intreating femoral shaft fracture without cannulated femoral reamer. Methods From January 2006 to June 2007, 24 cases offemoral shaft fracture were treated with closed reduction and intramedullary nail ing. Among them, there were 14 males and 10 females, with the average age of 38.3 years (ranging from 18 years to 63 years), with 7 left legs and 17 right legs. The average course of the disease was 7.6 days (ranging from 3 days to 20 days). According to the AO typing, there were 5 cases of type A, 6 of type B, 7 of type C1, 2 of type C2 and 4 of type C3. Closed reduction was achieved with manipulation and reaming of femoral canal was instructed by fluoroscopy. Results The operation time lasted from 100 minutes to 170 minutes, with the average time of 128.3 minutes. One patient was given a transfusion of 400 mL, and others were not. Twenty cases were followed up with the average time of 13.1 months (ranging from 6 months to 24 months). A mild to large amount of bony callus was showed on X-ray films 6 to 12 weeks postoperatively. Walking without crutches began at the average week of 22.2 (ranging from 15 to 30) postoperatively. Range of motion of the knee was 0° to 145.5°. No infection or break of the internal fixator occurred. Myositis ossificans with pain and insufficient flexion of hip (120°) happened in 1 case and the pain disappeared after non-steroid anti-inflammatory drugs were taken. Nonsymptomatic myositis ossificans occurred in 2 cases and no treatment was needed. Conclusion Closed reductionand intramedullary nail ing can help to protect the blood supply of fracture fragments and provide central fixation. The operation process will be more compl icated if cannulated femoral reamer is not available.
Objective To investigate the treatment of extensive bone defect of distal femur caused by various diseases in adults. Methods From February 1998 to December 2002, 6 cases(aged from 19 to 37) of extensive bone defects of distal femur were treated with two free vascularized fibulae, whose defects were caused by resection ofbone tumor, osteomyelitis and trauma. After the resection of distal femur and articular surface of tibia, the fibulae were transplanted and fixed with screws. And the periosteum of the two fibulae was dissected and sutured with each other.Results The average follow-up time was 3.3 years. Twofree vascularized fibulae could give more support to the body and the bone union of the fibulae was possible when the periosteum was incised and sutured with each other. As time went on, both of the medullary canal reunioned to form a new canal as a whole, which would make the grafts ber. Conclusion Autograft with two free vascularized fibulae can increase the stability in treating extensive bone defect of distal femur, but the union of knee joint will make flexion and extension impossible.

ObjectiveTo systematically review the postoperative infection-related complications between cemented and cementless hemiarthroplasty in elderly patients with femoral neck fracture.MethodsCochrane Library, PubMed, Embase, China Biology Medicine Database, Chongqing VIP China Science and Technology Journal Database, China National Knowledge Infrastructure, and Wanfang Database were searched to collect randomized controlled trials of postoperative infection-related complications between cemented and cementless hemiarthroplasty in elderly patients with femoral neck fracture from inception to January 2018. A systematic review was performed to compare the postoperative deep infection, superficial wound infection, pneumonia infection, and urinary tract infection between cemented and cementless hemiarthroplasty. Analyses were conducted using Review Manager version 5.2.0 software.ResultsA total of 11 studies were included in the Meta-analysis, including 1 533 patients. There was no significant difference in the incidence of deep infection [odds ratio (OR)=1.62, 95% confidence interval (CI) (0.66, 3.94), P=0.29], superficial wound infection [OR=1.17, 95%CI (0.56, 2.47), P=0.68], pneumonia infection [OR=0.73, 95%CI (0.47, 1.13), P=0.16], or urinary tract infection [OR=1.10, 95%CI (0.65, 1.86), P=0.73] between the two groups.ConclusionWhen selecting a fixation method for hemiarthroplasty to treat eldly patients with femoral neck fracture, infection-related postoperative complications are not the determinant factor to consider.
Objective To evaluate the effectiveness and safety of intraoperative tranexamic acid use in total shoulder arthroplasty. Methods By searching Cochrane Library, PubMed, Embase, Chongqing VIP, Chinese National Knowledge Infrastructure, Wanfang Database from the establishment of the database to September 2021, randomized controlled trials of intraoperative tranexamic acid use in total shoulder arthroplasty were collected. Outcome indicators were total blood loss, postoperative drainage, hemoglobin reduction, length of operation, length of hospital stay, and formation of hematoma. RevMan 5.3 software was used for meta-analysis. Results Meta analysis results showed that the use of tranexamic acid can reduce total blood loss [weighted mean difference = −246.55 mL, 95% confidence interval (−335.36, −157.75) mL, P<0.000 01], reduce postoperative drainage [weighted mean difference = −134.05 mL, 95% confidence interval (−161.72, −106.38) mL, P<0.000 01], reduce hemoglobin reduction [weighted mean difference = −0.64 g/dL, 95% confidence interval (−0.91, −0.36) g/dL, P< 0.000 01], reduce hematoma formation [risk ratio=0.41, 95% confidence interval (0.22, 0.77), P=0.005]. There was no statistically significant difference in the length of operation and length of hospitalization between patients who used tranexamic acid and those who did not use tranexamic acid (P>0.05). Conclusions Tranexamic acid is effective and safe for patients undergoing total shoulder arthroplasty. It can reduce perioperative bleeding and hematoma formation without increasing the length of surgery and hospitalization.
Objective To evaluate the efficacy and safety of tranexamic acid in arthroscopic anterior cruciate ligament reconstruction by meta-analysis. Methods The databases searched included Embase, PubMed, Cochrane Library, Wanfang, China National Knowledge Infrastructure and Chongqing VIP. The search time range was from the establishment of the databases to September 2022. All randomized controlled trials using tranexamic acid in arthroscopic anterior cruciate ligament reconstruction were collected. The outcome indicators were postoperative blood loss, postoperative joint cavity puncture rate, postoperative hematoma rate, postoperative Visual Analogue Scale score, and postoperative knee joint range of motion. RevMan 5.3 analysis software was selected for meta-analysis. Results A total of 6 articles were included, including 660 patients. Meta-analysis showed that the postoperative blood loss in the tranexamic acid group was lower than that in the control group [weighted mean difference (WMD)=−24.32 mL, 95% confidence interval (CI) (−33.73 mL, −14.91 mL), P<0.000 01]. The postoperative Visual Analogue Scale score in the tranexamic acid group was lower than that in the control group [WMD=−0.69, 95%CI (−1.21, −0.18), P=0.009]. The postoperative knee joint range of motion in the tranexamic acid group was higher than that in the control group [WMD=2.88°, 95%CI (0.55°, 5.21°), P=0.02]. The postoperative joint cavity puncture rate in the tranexamic acid group was lower than that in the control group [risk ratio (RR)=0.25, 95%CI (0.12, 0.53), P=0.0003]. The postoperative hematoma rate in the tranexamic acid group was lower than that in the control group [RR=0.40, 95%CI (0.21, 0.78), P=0.007]. Conclusion The patients who used tranexamic acid in in arthroscopic anterior cruciate ligament reconstruction have less postoperative bleeding, lower knee joint puncture rate and hematoma formation rate, which are conducive to pain relief and functional rehabilitation.
ObjectiveTo evaluate the clinical effectiveness and safety of platelet-rich plasma (PRP) in the arthroscopic repair of full-thickness rotator cuff injury.MethodsRelevant randomized controlled trials were identified from Cochrane Library, PubMed, Embase, China Biology Medicine Database, Chongqing VIP Database, China National Knowledge Infrastructure, and Wanfang Database (from the dates of establishment to September 2020). A systematic review was performed to compare the short-term and mid-term retear rates, the scores of the University of California at Los Angeles (UCLA) Shoulder Rating Scale, and the scores of Visual Analogue Scale (VAS) between the two groups. Analyses were conducted using RevMan 5.2.0 software.ResultsNine studies with low heterogeneity were included in the meta-analysis involving 610 cases (305 in the PRP group and 305 in the control group). There were significant differences in the short-term retear rate [relative risk (RR)=0.29, 95% confidence interval (CI) (0.13, 0.65), P=0.003], the short-term and the mid-term UCLA scores [standardized mean difference (SMD)=0.35, 95%CI (0.14, 0.56), P=0.000 9; SMD=0.87, 95%CI (0.53, 1.21), P<0.000 01], the short-term and the mid-term VAS scores [SMD=−0.29, 95%CI (−0.51, −0.07), P=0.009; SMD=−0.35, 95%CI (−0.66, −0.03), P=0.03] between the two groups. There was no significant difference in the mid-term retear rate [RR=0.88, 95%CI (0.48, 1.63), P=0.69] or complication rate [RR=1.40, 95%CI (0.78, 2.54), P=0.26] between the two groups.ConclusionsPRP injection can effectively improve the clinical outcomes following arthroscopic repair of full-thickness rotator cuff tears, thus reducing the short-term retear rate, alleviating pain, and improving patients’ shoulder function.
Objective To compare the clinical outcomes following arthroscopic repair for articular-sided partial rotator cuff tear using transtendon repair versus repair after completion of the tear by meta-analysis. Methods Randomized controlled trials on arthroscopic repair for articular-sided partial rotator cuff tear using transtendon repair versus repair after completion of the tear were identified from Cochrane Library, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang database, and Chongqing VIP database, with a timespan from the inception of database to November 2024. Pain score, American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, postoperative adhesive capsulitis and postoperative retear were obtained as the outcomes to compare the clinical effect of the two methods. Meta-analyses were conducted using RevMan 5.3 software, with mean difference (MD) and relative risk (RR) as the effect scales. Results A total of 6 randomized controlled trial studies were included in the meta-analysis. The studies enrolled 370 patients, including 188 cases in the transtendon repair group and 182 cases in the repair after completion of the tear group. Pooled analyses demonstrated that the pain score [MD=0.26, 95% confidence interval (CI) (0.09, 0.42), P=0.003] and ASES score [MD=2.02, 95%CI (0.95, 3.10), P=0.0002] were higher in the transtendon repair group than those in the repair after completion of the tear group, the Constant-Murley score was lower in the transtendon repair group than that in the repair after completion of the tear group [MD=−3.32, 95%CI (−6.17, −0.46), P=0.02], and there was no significant difference in the incidence of postoperative adhesive capsulitis [RR=1.12, 95%CI (0.36, 3.42), P=0.85] or the incidence of retear [RR=0.32, 95%CI (0.10, 1.03), P=0.06] between two groups. Conclusions Transtendon technique is less effective in reducing pain for articular-sided partial rotator cuff tear. There is no significant difference in the incidence of postoperative adhesive capsulitis or retear between the two gorups.
