ABSTRACT

BACKGROUND:At present, dexamethasone has been widely used in the perioperative period of major surgery in the orthopedics for reducing postoperative pain and nausea and vomiting, but the study on the application of methylprednisolone to reducing postoperative nausea and vomiting and pain after unilateral total knee arthroplasty is rarely reported.OBJECTIVE:To evaluate the effects and safety assessment of the application of methylprednisolone on postoperative nausea and vomiting and pain after unilateral total knee arthroplasty. METHODS:A total of 86 patients undergoing unilateral total knee arthroplasty were randomly assigned to two groups. Patients in the methylprednisolone group were given methylprednisolone 40 mg in intravenous drip within 24 hours during and after replacement. Patients in the control group were given an equal volume of saline in intravenous drip at the same time. The incidence of postoperative nausea and vomiting was observed and recorded at 0-6 hours, 6-24 hours, 24-48 hours, and 48-72 hours after surgery, as wel as the total incidence was recorded in both groups. Pain visual analogue scale (VAS) score at 6, 24, 48 and 72 hours after replacement, and knee joint scoring system (KSS) score at 3 days after replacement were recorded. C-reactive protein and fasting blood glucose were determined. The occurrence of adverse reactions postoperatively was recorded in 6-month fol ow-up in both groups. RESULTS AND CONCLUSION:(1) The total incidence rate of postoperative nausea and vomiting during 0-72 hours after surgery, and incidence rates of nausea and vomiting at 6 and 24 hours were significantly lower in the methylprednisolone group than in the control group (P0.05). (5) The surgical incision was found to heal in 3-month fol ow-up and no postoperative infection occurred in both groups. (6) Results show that methylprednisolone can obviously reduce postoperative nausea and vomiting and pain in unilateral total knee arthroplasty, and did not increase the incidence of postoperative infection.

ABSTRACT

Objective To evaluate the clinical results of arthroscopic arthrolysis for the treatment of elbow stiffness.Methods Totally 34 cases with elbow stiffness caused by trauma who needed to undergo arthroscopic arthrolysis were selected from General Hospital of Shenyang Military Area Command from October 2014 to February 2016.Among them,3 cases were lost to follow-up,and the other 31 cases were included in the study.All the patients were performed arthroscopic arthrolysis.Removed the hyperplasia of osteophyte and girdle,cleaned the articular cavity,restored the smooth of articular surface,and released the joint capsular and ligament around the elbow joint during the operation.Manipulation release was used coordinate with analgesia and rehabilitation therapy after operation.Mayo scores of elbow were used for function evaluation and range of motion(ROM) was collected.Results Patients were followed-up from 9 months to 12 months,(10.4±1.5) months on average.Before the operation,the mean maximal flexion angle of the elbow was (87.6±5.9)°,the extension angle was (35.5±6.4)°,the pronation angle was (75.9±9.6)°,the rotational angle was (67.2±7.4)°,and it was (125.9±6.5)°,(5.0±1.9)°,(82.0±9.1)°,(81.0±7.0)°respectively after operation,and the differences before and after opreation were statistically significant (P<0.05).The Mayo scores was (61.9±7.6) preoperatively and (88.8±4.7) postoperatively,and the difference was statistically significant(P<0.05).Conclusion Arthroscopic arthrolysis has the advantages of clear operative field,minimal invasion and rapid recovery.It can effectively improve the elbow joint activity and arthroscopic arthrolysis is an effective surgical treatment for elbow stiffness.

ABSTRACT

Objective To analyze the short-term clinical efficacy of the treatment of ipsilateral femoral intertrochanteric fractures with femoral head necrosis through total hip arthroplasty combined with internal fixation.Methods From January 2011 to June 2014 a total of 28 cases of ipsilateral femoral intertrochanteric fractures with femoral head necrosis were selected,and they were all treated with open reduction and greater trochanter plate fixation combined with total hip arthroplasty.The time of operation, amount of bleeding,time of bone healing of the greater trochanteric fracture,postoperative complications, rate of internal fixation device loosening,incidence of infection,and the Harris score of the hip joint before and after operation were recorded and statistically analyzed.Results The mean operative time was (174.0±27.1)min and the mean blood loss was (530.0±132.0)mL.There were 2 cases of deep venous thrombosis in the lower extremities,and there was no serious complications occured among the remaining cases.All patients were followed up for 12 to 24 months,averagely (16.3±7.0) months.All the 28 patients get bony union of the large trochanter,with the average healing time of (5.0±1.5) months.The preoperative Harris score was (28.0±7.1) points, while it was (86.5±5.3) points after the surgery, and the difference was statistically significant(t=-21.699,P=0.000).At the end of the follow-up,there was no internal fixation device loosening, no cable breakage,and no infection cases.Conclusion Total hip arthroplasty combined with internal fixation for the treatment of ipsilateral femoral intertrochanteric fractures with femoral head necrosis, especially the large trochanteric fractures, were of reliable fracture fixation, good initial stability and good joint function recovery.And it can maintain fracture stability and early recovery of joint function,so that intertrochanteric fractures and femoral head necrosis were treated simultaneously,and its recent clinical results were satisfactory.

ABSTRACT

Objective To investigate the clinical significance of serum interleukin-6(IL-6),C-reactive protein(CRP) and procalcitonin(PCT) in early diagnosis of postoperative infection after artificial femoral head replacement in rabbits.Methods Selected 64 healthy New Zealand white rabbits,and randomly divided them into the experimental group and the control group,with 32 cases in each group.All of the 64 rabbits underwent left femoral hip replacement.Rabbits in the experimental group were injected with staphylococcus aureus into the left hip joint immediately after artificial femoral head replacement,while rabbits in control group were injected with the same amount of saline.The changes of IL-6,CRP and PCT in synovial fluid of all rabbits were measured.Took synovial fluid and 3 pieces of synovial membrane to make bacterial culture 9 days after surgery.Results The bacterial culture of the experimental group was positive for staphylococcus aureus while it was negative in the control group.One day after surgery,the levels of IL-6,CRP and PCT in synovial fluid of two groups were significantly higher than those before operation(P0.05).The levels of IL-6,CRP and PCT in the synovial fluid of the experimental group were significantly higher than those of the control group at the 3rd,6th and 9th day after operation(P0.05),and IL-6 and CRP gradually restored preoperative level at 9th days after operation(P>0.05).The sensitivity and specificity of IL-6,CRP and PCT combined test were 96.9% and 90.6% respectively,which were significantly higher than those of individual indexes.Conclusion Combined detection of serum IL-6,CRP and PCT levels in the infection model of artificial femoral head replacement can provide some help for the early diagnosis of infection after clinical hip arthroplasty.
