Objective To explore the intraoperative imaging to monitor the prosthetic fixation for the total hip arthroplasty (THA) and to increasethe accuracy of the primary THA prosthetic fixation. Methods From April 2000 to August 2005, 69 patients (75 hips) underwent THA monitored by the imaging (the imaged THA group, Group I), and 72 patients (78 hips) underwent THA with the standard method (the standard THA group, Group S). There were 32 males and 37 females in Group S. The mean ages of the patients in Group I and Group S were 62.3 years and 60.5 years respectively, ranging 46-75 years in Group I and 43-75 years in Group S. Preoperative diagnoses were femoral neck fracture (Garden Ⅲ,Ⅳ) in 23 patients (23 hips) in Group I and 25 patients (25 hips) in Group S, acetabular dysplasia (Campbell Ⅰ, Ⅱ) in 9 patients (10 hips) in Group I and 11 patients (13 hips) in Grouop S, osteoarthritis in 16 patients (17 hips)in Group I and 15 patients (15 hips) in Group S, femoral head osteonecrosis (Ficat Ⅲ,Ⅳ) 15 patients (16 hips) in Group I and 17 patients (17 hips) in Group S, and rheumatoid arthritis in 6 patients (9 hips) in Group I and 4 patients (8 hips) in Group S. There were 21 hips of cement prostheses in Group I and 22 hips in Group S, 12 hips of cementless prostheses in Group I and 11 hips in Group S, 42 hips of cement and cementless prostheses in Group I and 45 hips in Group S. Group I used the standard THA and the intraoperative X-ray monitoring the prosthetic fixation in the numerical measure of abduction angle, anteversion angle, femoralneck length, and femoral offset distance. The items compared betweem Group I and Group S included incisional length, intraoperative bleeding, transfusion, operative time, frequency of X-ray imaging, infection, postoperative functional recovery, and prostheric position of postoperative X-ray imaging. Results The follow-up on 62 patients in Group I and 64 patients in Group S for 6-64 months averaged 42 months revealed that there were statistically significant differences in incisional length, intraoperative bleeding, transfusion, operative time, frequency of X-ray imaging, postoperative functional recovery, prosthetic position of postoperative X-ray imaging, and the Harris score between Group I and Group S one year after operation. The results of Group I were significatly better than those of Group S. Conclusion The intraoperative X-ray imaging can increase the accuracy of the THA prosthetic fixation and reduce the incidence of THA maloperation by The X-ray imaging can also be used in county hospitals if Carm fluoroscopy can be provided.
Objective To estimate the clinical curative effect of replacement of inverttype artificial total scapula and shoulder joint prosthesis and reserving arm with rehabilitation of function in the treatment of malignant tumor in shoulder. Methods From February 2001 and November 2004, five youth patients with primary malignant shoulder tumors were treated operatively by resection of neoplasmsthoroughly, replacement of inverttype artificial total shoulder blade and joint prosthesis, the functional reconstruction. Of them, there were 4 males and 1 female, aging from 19 to 26 years with an average of 23.6 years. Two cases were diagnosed as having osteosarcoma, one as having chondrosarcoma, and 2 as having Ewing sarcoma. After operation, the upper limbs was immobilized for 3 weeks. The rehabilitation training including passive exercise and initiative exercise. Results The average operative time was 425 min (380 to 530 min), and the blood loss ranged from 1 250 ml to1 900 ml(1 540 ml on average). The follow-up ranged from 7 to52 onths,with an average of 24.6 months. Postoperative complication included 1 case of pneumothorax, one case of shoulder incision skin part necrosis and 1 case of clavicle stump raising and pierce skin with shallow infection. No complication of postoperative incision deeply infection, nerve damage and prosthesis exposure or dislocation occurred. According to the scoring system of JOA(Japan orthopaedics association), the average score was 65 (60 to 72). The flexion and extension function of elbow joint recovered to normal. Conclusion The replacement of inverttype artificial total scapula and shoulder joint prosthesis is an efficacious method for the treatment of malignant tumor in shoulder. There are advantages of numerous adaption, wide range of motion and goodstability. It can not only reserve arm but also rehabilitate function.
Objective To study the effect of all-coated long stem prosthesis associated with allograft in revision total hip replacement (THR). Methods From January 1997 to January 2004, 20 patients with non-infectious loosened implant after primary THR were treated. There were 12 males and 8 females with a mean age of 65 years (58-77 years). The average period between primary THR and revision THR was 12 years (3-18 years). According to classification of Paprosky, there were10 cases of type II, 6 cases of type IIIA, 3 cases of type IIIB and 1 case of type IV. All-coated long stem prosthesis was used in all cases. Impacting bone grafting was done in 12 cases and impacting bone grafting associated with cortical strut grafting in 8 cases. The mean amount of morsel ized bone was 20 g (5-35 g), the length of cortical bone was 10-22 cm. Results All the incisions got heal ing by first intension. All patients were followed up for an average period of 36 months (16-48 months). Dislocation occurred at 5 days after operation and was cured with closed reduction and traction in 1 case. There was significant difference (P lt; 0.05) in the mean Harris score between preoperation (50.0 ± 2.3) and postoperation (90.0 ± 2.5). The X-ray checking showed that continuous radiolucent l ine of 3 mm occurred in 1 case, prosthesis subsidence of 5 mm and 7 mm in 2 cases and that no bone absorption was observed. Seven cases of cortical bone grafting union was achieved within 3 years except 1 case of cortical bone un-union. Conclusion It can obtained the initial stabil ization of prosthesis to use all-coated long stem prosthesis associated with allograft in revision THR to treat femur bone defect after THR. The short-term effects of the cl inical and X-ray checking are satisfactory, but future effect is to be observed.
Objective To explore the clinical application of the postanesthetic autologus donation and the post-operative transfusion during the knee and hipreplacement surgeries. Methods Thirty-three patients (17 males,16 females) admitted for the elective joint replacement surgeries from September 2004 to January 2005 were included in this study. Of the 33 patients, 5 were diagnosed with rheumatoid arthritis, 23 with femoral head necrosis, and 5 with knee osteoarthritis. Immediately after anesthesia, 400 ml of the blood was drawn and transfused after the surgery. The blood pressure was monitored during the blood drawing, postoperative blood parameters were recorded, surgical site drainage and signs of infections were observed, and the other clinical data were collected.Results Of the 33 patients, 27 only received autologoustransfusion, including 21 patients who underwent the unilateral hip replacement and 6 patients who underwent the unilateral knee replacement. All these 6 patients with the unilateral knee replacement received the blood drained from the surgical sites in addition to the blood obtained from the postanesthetic autologous donation. Another 6 cases with the bilateral hip and knee replacement received the blood drained from the surgical sites, the blood obtained from the post-anesthetic autologous donation and 400 ml of the allogeneic blood transfusion. The blood received postoperatively averaged 650 ml (range, 200-1 150 ml), haemoglobin(Hb) was averaged 88 g/L (68-102 g/L), and Hct was averaged 24.6% (20.5% 31.5%). Hb and Hct were lower after operation than before operation(Plt;0.01). Conclusion Postoperative blood transfusion following the postanesthetic and preoperative autologous donation can be successfully applied to most of the patients undergoing theknee or hip replacement so as to reduce complications of the allogeneic blood transfusion.
ObjectiveTo investigate and analyze comorbidities of elderly patients with total hip/knee arthroplasty, so as to provide a basis for the management of comorbidities.MethodsConvenience sampling was used to select elderly patients who underwent total hip/knee arthroplasty in the Department of Orthopedics in West China Hospital of Sichuan University from June to December 2019 as the research objects. We collected general data and comorbidity data of patients, and statistically analyzed the comorbidities of elderly patients undergoing total hip/knee arthroplasty, and the characteristics of perioperative psychology, sleep, postoperative complications, and length of hospital stay in elderly patients undergoing total hip/knee arthroplasty with comorbidities.ResultsA total of 263 patients were included, of whom 64.6% had comorbidities. The number of comorbidities in elderly patients undergoing total hip/knee arthroplasty ranged from 2 to 12. The most common comorbidity was hypertension. Between patients with comorbidities and non-comorbidities, there were statistically significant differences in age (Z=−2.225, P=0.026), preoperative Huaxi Emotion Index scores (9.6±4.6 vs. 6.4±5.0; t=5.126, P<0.001), preoperative Pittsburgh Sleep Quality Index scores (13.3±3.1 vs. 12.3±2.5; t=−2.972, P=0.003), hospital stay [(5.2±0.8) vs. (4.8±0.4) d; t=4.243, P<0.001], and incidence of postoperative complications (13.5% vs. 5.4%; χ2=4.201, P=0.040).ConclusionsComorbidities are common in elderly patients with total hip/knee arthroplasty, which may aggravate negative emotions, reduce sleep quality, increase postoperative complications and prolong length of stay. Medical staff should strengthen the management of comorbidity in elderly patients with total hip/knee arthroplasty, so as to reduce its influence on perioperative period and promote the rehabilitation of patients.
OBJECTIVE To review the history and current status of total wrist arthroplasty. METHODS The original articles about wrist arthroplasty in recent years were reviewed. RESULTS The properties of wrist prosthesis of different generations were reviewed, with the emphasis on the prosthesis design and biomechanical behaviours. The surgical techniques, complications and salvage procedures were also discussed. CONCLUSION Although wrist arthrodesis is highly successful in treating the end-stage wrist arthritis, total wrist arthroplasty using well-designed prosthesis remains an alternative for the patients with special demands of hand functions.
ObjectivesTo explore the status quo of the readiness for hospital discharge and the quality of discharge guidance in patients after total hip/knee arthroplasty, and analyze their correlations.MethodsA cross-sectional survey was conducted to investigate patients who underwent total hip/knee arthroplasty in a tertiary hospital in Chengdu between January and November 2017. The survey included basic patient information questionnaire, Readiness for Hospital Discharge Scale, and the Quality of Discharge Teaching Scale.ResultsThe average age of 352 patients undergoing total hip/knee arthroplasty was (59.56±12.69) years. The total score of readiness for hospital discharge was 177.08±19.41, the average score was 7.82±0.88, and the average quality of discharge teaching was 145.87±14.87. There was a statistically significant difference between the patients’ access and the required discharge teaching (t=28.742, P<0.001). The score of readiness for hospital discharge was positively correlated with the score of the quality of discharge guidance (r=0.645, P<0.001), the obtained content dimension (r=0.542, P<0.001), and the teaching skill dimension (r=0.522, P<0.001).ConclusionsThe readiness for hospital discharge in patients after total hip/knee arthroplasty is in a medium level, and the quality of discharge teaching is higher overall and it is positively correlated with the readiness for hospital discharge. Medical staff should pay attention to the discharge guidance for patients. In the course of health education, not only the content and quantity of guidance should be emphasized, but also the guiding skills should be paid attention to, so as to improve the quality of discharge teaching, thereby improving the patient’s discharge readiness and promoting the patient’s later rehabilitation.
ObjectivesTo systematically review the efficacy and safety of controlled hypotension for total hip or knee replacement.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) on controlled hypotension for total hip or knee replacement from inception to September 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 15 RCTs involving 854 patients were included. The results of meta-analysis showed that compared with no controlled hypotension during surgery, controlled hypotension could reduce intraoperative blood loss (MD=−267.35, 95%CI −314.54 to −220.16, P<0.000 01), allogeneic blood transfusion (MD=−292.84, 95%CI −384.95 to −200.73, P<0.000 01), and 24 h postoperative mini-mental state examination (MMSE) score (MD=−1.08, 95%CI −1.82 to −0.34, P=0.004). However, there were no significant differences in 96 h postoperative MMSE score (MD=−0.11, 95%CI −0.50 to 0.28, P= 0.57) and intraoperative urine volume (MD=57.93, 95%CI −152.57 to 268.44, P=0.59).ConclusionsThe current evidence shows that controlled hypotension during total hip or knee replacement can reduce intraoperative blood loss and allogeneic blood transfusion. Furthermore, there is no obvious effect on the maintenance of blood perfusion in important organs, despite certain effects on the postoperative cognitive function, which can be recovered in short term. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To analyze the influence of the body mass index (BMI) and age on deep vein thrombosis (DVT) after the total hip arthroplasty(THA) or total knee arthroplasty(TKA) in Chinese patients who received prophylactic treatment for DVT. Methods We used a randomized clinical case-control study. From April 2004 to August 2004, weperformed THA and TKA for 95 patients (128 hips and knees). There were 27 men and 68 women with an average age of 60 years (range, 23-78) at surgery, and withan average BMI of 25.88 kg/m2 (range, 14.34-40.39) before surgery. All the patients were given low-molecular-weight heparin for 7-10 days pre-and postoperatively to prevent DVT. Color Doppler ultrasonography was used to detect DVT of bilateral lower extremities in all the patients before operation and 7-10 days after operation.The patients were divided into 4 groups according to their BMI:the non-obese group (BMI≤25.00 kg/m2), the overweight group (BMI, 25.01-27.00 kg/m2), the obese group (BMI, 27.01-30.00 kg/m2), and the morbidly obese group (BMIgt;30.00 kg/m2); and they were also divided into 4 groups according to their ages (≤40, 4160, 61.70, gt;70 yr) so as to analyze the influence of the BMI and age on DVT. Results The total incidence ofDVT in all the patients was 47.4% (45/95) and the incidence of proximal DVT was 3.2%. Forty-five patients had DVT and 50 patients had no DVT. The average BMI of the patients with DVT was significantly higher than that of the patients with no DVT (Plt;005). The overweight, obese, and morbidly obese patients had an odds ratio of 7.04, 4.8,and 9.6 for DVT compared with the nonobese patients (P＜0.05); but the obese group had a less risk than the other 2 groups.The 41-60, 61-70, and gt;70-year-old patients had an odds ratio of 24.0, 38.2, and 24.4 for DVT compared with the ≤40year-old patients (P＜0.05). Conclusion Obesity (BMIgt;25 kg/m2) and an increasing age (gt;40 yr) are identified as statistically significant risk factors for DVT after THA or TKA, and patients aged 61-70 years are more likely tohave DVT than the other patients. We should pay more attention to those obesity and aged patients when they are undergoing the total joint replacement, and we should give them enough prophylaxis and closely observe the symptoms in their bilateral lower extremities after operation, taking ultrasonography or venography to check DVT if necessary, so that we can give them prompt treatment and prevent fatal pulmonary thromboembolism.
Objective To evaluate differences of clinical effects between cervical total disc replacement (TDR) and anterior cervical discectomy and fusion (ACDF) for single symptomatic single-level cervical degenerative disc disease. Methods Randomized controlled trials (RCTs) from the Cochrane Library Central Register of Controlled Trials (Issue 1, 2009), MEDLINE (2000 to May 2009), EMbase (2000 to May 2009), Ovid (2000 to May 2009), CBM (2000 to May 2009) and CNKI (2000 to May 2009) were electronically searched. Additionally, six relevant journals were handsearched to identify RCTs about comparison of TDR and ACDF in the treatment of single-level cervical degenerative disc disease. All RCTs demonstrating these issues were included. RevMan 5.0 software was used for meta-analyses. Results Six RCTs involving 1 340 patients were included. The results of meta-analyses indicated that there were significant differences between the two groups in neurological success (RR=1.06, 95%CI 1.02 to 1.11, P=0.003), secondary surgical procedures (RR=0.30, 95%CI 0.17 to 0.53, Plt;0.0001) and overall success (RR=1.13, 95%CI 1.06 to 1.22, P=0.0006). However, there were no significant differences in Neck Disability Index (NDI) scores (WMD=1.53, 95%CI –0.55 to 3.61, P=0.15), neck pain scores (WMD= –2.87, 95%CI 7.75 to 1.81, P=0.23), arm pain scores (WMD= –0.7, 95%CI –0.86 to –0.54, P=0.48), radiography success (RR=0.96, 95%CI 0.92 to 1.01, P=0.11), and postoperative complications (RR=0.79, 95%CI 0.49 to 1.28, P=0.34) between the two groups. Conclusion The evidence indicates that compared with ACDF, TDR could improve neurological status, reduce secondary surgical procedures and promote overall success for single-level cervical degenerative disc disease, but there are no significant differences in postoperative NDI, neck and arm pain scores, radiography success, and complications.
