OBJECTIVE There are various methods used to treat the Kienbock’s disease with various outcomes. This study investigated the effect of combining acrylic lunate prosthesis replacement with resection of articular branches to wrist from anterior and dorsal interosseous nerve. METHODS From January 1992 to January 1997, six cases were included. All of the patients were in stage III according to Lichtman’s classification. Besides replacement of the acrylic lunate prosthesis, segment of the pure sensory branches from anterior and posterior interosseous nerves were resected. RESULTS Follow-up for 10 to 54 months (an average of 32 months) the pain was relieved in all patients except one. The range of movement of wrists were as followings: The extension of the wrist was 20 to 35 degrees (an average of 26 degrees) and flexion was 20 to 35 degrees (an average of 32 degrees). There was no improvement in radial and ulnar deviation. CONCLUSION Lunate prosthesis replacement combined with resection of articular branches to wrist resulted in a painless wrist and was a satisfactory method.
Objective To investigate the clinical effect of orthopedic robot-assisted sacroiliac joint screws in the treatment of posterior pelvic ring fractures. Methods Patients who underwent sacroiliac joint screw fixation in People’s Hospital of Deyang City between January 2018 and August 2021 were included, and the patients were divided intoa robotic group and a manual group by randomization. The robot group used robot-assisted insertion of sacroiliac joint screws, and the manual group used manual insertion of sacroiliac joint screws. The general condition, time of sacroiliac joint screw placement, intraoperative fluoroscopy times, guide needle drilling times, surgical blood loss, and Majeed pelvic function score were compared between the two groups. Results A total of 42 patients were included, and there was no significant difference in gender, age, body mass index , injury type or injury cause between the two groups (P>0.05). Finally, 21 screws were placed in 19 patients in the robotic group and 23 screws in 23 patients in the manual group. The wounds of the two groups were completely healed after operation, and there was no wound infection, iatrogenic vascular and nerve injury, and no loosening of internal fixation. There was no significant difference in screw placement time, blood loss or Majeed score between the two groups (P>0.05). The number of fluoroscopy (14.53±4.54 vs. 19.87±5.48) and drilling times (1.00±0.00 vs. 7.24±3.77) in the robotic group were less than those in the manual group, and the differences were statistically significant (P<0.05). Conclusion Orthopedic surgical robots have the advantages of minimally invasive, less fluoroscopy, and accurate screw placement in sacroiliac joint screw placement, and have good clinical results in the treatment of pelvic fractures.
Objective To observe the effect of Chinese Herbal Preparation -Mingjing Granule on the recruitment and adhesion of bonemarrow derived cells (BMCs) to choroidal neovascu1arization (CNV) in mice induced by laser photocoagulation. Methods A total of 75 C57BL/6 mice were divided into treatment group (30 mice), control group (30 mice) and normal control group (15 mice). CNV was induced by krypton laser in the mice of treatment group and control group. BMCs from GFPtransgenic mice were injected through tail vein to those mice 0.5 -1.0 hours after laser surgery. On day one after laser surgery, the mice of treatment group were gavaged with 0.3 ml Mingjing Granule solution every day［30 g/(kg?d)］, while the control group mice were gavaged with distilled water. The mice of normal group fed with normal cereals. 7, 14, 28 days after treatment, choroidal flatmount were prepared to measure the CNV severity and BMCs recruitment. The choroidal histopathological change was observed by optical microscope. CXCR4 level in peripheral blood was measured by enzymelinked immuno sorbent assay (ELISA). Stromal cell derived factor1alpha; (SDF-1alpha;), vascular cell adhesion molecule-1 (VCAM-1), inter-cellular adhesion molecule 1 (ICAM-1) were detected by immunofluorescent staining. Results Choroidal flatmount showed that CNV developed in treatment group and control group, but not in normal group. On day seven and 14, CNV lesions in the treatment group showed less incorporation of BMCs and smaller CNV in size compared with the control group (t=10, 9; P=0.007, 0.024), histologic sections also showed less severe lesions in the treatment group. CXCR4 level in peripheral blood in the treatment group was less than that in the control group and normal control group on day seven and day 14（t=8.107, 2.747;P＜0.05). The expression of SDF-1alpha;, ICAM-1 and VCAM-1 in the treatment group was lower compared with the control group. Conclusions Mingjing Granule could inhibit the recruitment and adhesion of BMCs in peripheral blood to CNV at the early stage. The mechanism may be related with the action of Mingjing Granule in lowing chemokines levels in peripheral blood and expression of adhesion molecules around CNV.
Objective To explore the clinical effect of multidisciplinary team (MDT) in elderly patients with hip fracture under the model of close-type medical alliance. Methods The elderly patients with hip fracture treated in the Department of Orthopedics of Deyang People’s Hospital between January 2015 and December 2020 were included retrospectively. According to different treatment modes, the patients were divided into traditional mode treatment group (traditional group) and MDT mode treatment group (MDT group). The waiting time for operation, hospitalization time after operation, total hospitalization time, total hospitalization cost, and death and loss of follow-up were analyzed. Results A total of 661 patients were enrolled, including 275 in the traditional group and 386 in the MDT group. There was no significant difference between the two groups in terms of gender, age, Charlson comorbidity index, types of fracture or surgical methods (P>0.05). The waiting time for operation [5.50 (3.50, 7.50) vs. 6.00 (4.00, 6.00) d; Z=−3.473, P=0.001], hospitalization time after operation [7.44 (6.27, 8.67) vs. 8.34 (6.72, 13.70) d; Z=−4.996, P<0.001] and total hospitalization time [12.95 (10.46, 16.30) vs. 15.49 (11.77, 19.91) d; Z=−5.718, P<0.001] in the MDT group were shorter than those in the traditional group. The total hospitalization cost of the MDT group was higher than that of the traditional group, but the difference was not statistically significant [39 300 (33 400, 46 400) vs. 38 000 (31 800, 44 000) Yuan; Z=1.524, P=0.128]. There was no significant difference in the lost follow-up rate between the traditional group and the MDT group (9.82% vs. 6.48%; χ2=2.474, P=0.116). Except in-hospital mortality and 30-day postoperative mortality (P>0.05), there was significant difference between the traditional group and the MDT group in 6-month (6.45% vs. 2.77%; χ2=4.875, P=0.027) and 1-year (11.29% vs. 6.37%; χ2=4.636, P=0.031) postoperative mortality. Conclusion Under the model of close-type medical alliance, MDT can reduce the waiting time for operation, hospitalization time after operation, total hospitalization time, as well as 6-month and 1-year postoperative mortality.
Objective To summarize the cl inical characteristics of 596 patients with fracture in Wenchuan earthquake and to investigate the therapeutic methods and effects of early treatment. Methods From May 12th 2008 to May 21st 2008, 596 patients with fracture caused by Wenchuan earthquake were treated, including 283 males and 313 females aged1.9-102 years (median 43 years). The time from injury to hospital ization varied from 12 minutes to 4 days. There were 132 cases of upper extremity fracture, 496 cases lower extremity fracture, 10 cases clavicular fracture, 16 cases scapular fracture, 23 cases pelvis fracture, and 59 cases spinal fracture. Among them, 183 cases were open fracture and 413 cases were closed fracture. And 214 cases had multiple fracture (35.9%) and 68 cases had crush injury in l imbs which scored (6.84 ± 2.48) points according to the mangled extremity severity score (MESS). Thirty-six cases were combined with neurovascular injury. The wound of the open fracture was contaminated at different degrees, but no gas gangrene was observed. Open fracture was treated with suturing or no suturing after debridement, open reduction and internal or external fixation. Closed fracture was fixed with spl ints, cast and traction. Forty-nine patients whom were highly suspected as osseous fascia compartment syndrome received incision decompression timely, and 34 patients whose MESS were above 7.0 points or suffering from crush injury of l ifethreatening systemic symptoms received amputation. Results Apart from 34 patients receiving amputation, 460 patients achieved functional reduction of fracture after manipulative reduction and 102 cases got satisfactory reduction after surgery. Postoperatively, 289 patients were transferred to other hospitals. Among the rest 307 patients, 34 with severe wound infection were healed after multiple debridement, anti-infection, and skin flap transplantation (16 cases healed by first intention and 18 cases healed by second intention), 42 cases with crush syndrome were treated with open decompression and amputation, and nodeep venous thrombosis of lower l imb, stress ulcer and death were observed after operation (29 cases healed by first intention and 13 cases healed by second intention). Conclusion By aiming at the features of fracture caused by earthquake, the prompt and professional treatment can achieve good therapeutic effects.
Objective To retrospectively analyze the 420 fractured inpatients in the People’s Hospital of Deyang city seven days after the Wenchuan earthquake, so as to provide reference for the improvement of emergency plans earthquakes and the subsequent treatment of fracture patients. Methods The analysis was based on the data provided by the Department of Orthopedics of the Hospital up until July 18,2008. The software Microsoft EXCEL was used for data input, and SPSS 13.0 was used for statistical analysis. Results Up to July 18 420 cases from the disaster area have been treated in the department of orthopedics, including 176 men (41.9%) and 244 women (58.1%), the age was from 1 to 102 years and a median age of 43 years (2 761) among the inpatients. Most patients(328 cases) were sent to the hospital within the first three days after the quake (78.1%), and the number of inpatients were 92 4-7 days after the quake. The wounded were mainly from Mianzhu,Shifang , and Guanghan. The admission fracture diagnoses were tibial fractures (18.8%), fibular fractures (16.6%), and femoral fractures (14.9%). The major treatments were splinting, plaster fixation, or traction for closed fractures (301 cases), internal fixation or external fixation for malreduction (85 cases), and debridement suture and plaster fixation for open fractures (78 cases). Conclusion It is a vital to develop an emergent plan for fracture patients after an earthquake disaster and to strengthen the reserve of medical supplies, personnel training, and individual therapy.
ObjectiveTo compare the biomechanical properties between the proximal femoral locking plate and Gamma3 for fixing stable intertrochanteric fracture so as to provide a theoretical basis for selecting internal fixation in the clinical application. MethodsFive pairs of antiseptic femur specimens were selected. Specimens of each pair of matching were randomly divided into groups A and B (n=5). All specimens were made the intertrochanteric fracture of 31A1.1 type according to AO/Association for the Study of Internal Fixation (AO/ASIF) classification. Fracture was fixed with Gamma3 in group A and with proximal femoral locking plate in group B. The axial compression, destruction, and torsion tests were carried out on the mechanical testing machine. ResultsAxial compression test:The load-displacement curve of groups A and B was basically a straight line; axial stiffness of groups A and B was (621.00±36.48) N/mm and (542.55±46.94) N/mm respectively, showing significant difference (t=3.648, P=0.036). Destruction test:The maximum yield load of groups A and B was (4 394.82±450.37) N and (2 987.54±112.14) N respectively, showing significant difference (t=5.433, P=0.032). After loading maximum yield load, femoral fracture occurred again, and internal fixation and bone interface loosening were observed in group A; bending and breaking of proximal locking screw for internal fixation were found in group B, but loosening of internal fixation and bone interface was more obvious in group A than in group B. Torsion test:The torque of specimens in 2 groups increased with the increase of torsion angle (P < 0.05), the torque corresponding to the torsion angle in group B was larger than that in group A, but the difference was not significant (P > 0.05). The torsional stiffness of groups A and B was (1.78±0.16) N·mm/deg and (2.01±0.08) N·mm/deg respectively, showing no significant difference (t=-3.833, P=0.162). ConclusionProximal femoral locking plate and Gamma3 in the treatment of stable intertrochanteric fracture have good biomechanical properties, which can meet the requirements of minimal invasion, strong internal fixation, and early activity.
Objective To compare the clinical effects of traditional manual and robot-assisted implantation of cannulated screws in the treatment of femoral neck fracture. Methods The medical records of patients with femoral neck fracture in Department of Orthopaedics, People’s Hospital of Deyang City were analyzed retrospectively. The patients were divided into two groups, including the traditional manual implantation group from January to December 2018 and the robot-assisted implantation group from May 2019 to May 2020. The clinical therapeutic efficacy of the two groups were compared. Harris hip function score was used to evaluate hip function. Results A total of 85 patients were included. All patients had closed fractures. There were 45 cases in the traditional manual implantation group and 40 cases in the robot-assisted implantation group. There was no significant difference between the two groups in preoperative waiting time, operation time, hospitalization time, fracture healing time, complications within one year after operation, or Harris hip function score one year after operation (P>0.05). The placement nail time [(11.1±2.0) vs. (23.8±2.3) min; t=27.142, P<0.001], frequency of guide pin insertion [(4.7±1.2) vs. (11.4±1.7) times; t=20.640, P<0.001], frequency of intraoperative fluoroscopy [(10.8±1.7) vs. (21.0±1.8) times; t=26.990, P<0.001] and intraoperative blood loss [(8.1±2.0) vs. (12.0±1.7) mL; t=9.711, P<0.001] in the robot-assisted implantation group were less than those in the traditional manual implantation group. No wound infection or neurovascular injury was found in the two groups. Conclusion Robot-assisted implantation of cannulated screws in the treatment of femoral neck fracture has the advantages of less fluoroscopy, fewer guide pin insertion, less blood loss, more accurate screw placement than the traditional manual implantation of cannulated screws.
