Objective To review and summarize the multimodal analgesia regimen in total hip arthroplasty (THA), and to provide basis for individual analgesia in clinic. Methods The literature of multimodal analgesia regimen in THA in recent years was systematically searched and summarized. The perioperative pain management regimens of THA in authors’ center were introduced at the same time. Results Postoperative pain of THA is an important factor affecting patient satisfaction, so pain management is one of the key points in perioperative management of THA. At present, multimodal analgesia regimen is used in THA, which works by blocking pain conduction pathway at different levels, including wound ice compress, non-steroidal anti-inflammatory drugs, local infiltration anesthesia, peripheral nerve block, intraspinal anesthesia, central analgesics, and so on. Conclusion Multimodal analgesia regimen is the perioperative pain management of THA, which includes many analgesic methods. The safe and effective analgesic methods should be chosen according to the specific conditions of patients in order to achieve individualized analgesia.
ObjectiveTo summarize the research progress of total hip arthroplasty (THA) in treatment of sequelae of suppurative hip arthritis.MethodsThe relevant literature was systematically searched and the operation timing, treatments of acetabular and femoral sides, and prosthesis selection in THA for sequelae of suppurative hip arthritis were summarized.ResultsTHA is an effective way to treat the sequelae of suppurative hip arthritis. In order to avoid the recurrence of infection, THA is recommended to be performed after 10 years of resting period of hip septic infection. These patients may have acetabulum dysplasia and poor coverage of acetabulum. When performing THA, high position acetabulum, osteotomy of the medial acetabular wall, structural bone graft, Cage, tantalum augment, or three-dimensional printing prosthesis can be chosen. The femoral side may has small medullary cavity, increased femoral neck anteversion, increased femoral neck-stem angle, extend trochanter, and poor bone mass. When performing THA, the femoral osteotomy and appropriate prosthesis can be selected for treatment. The patients with sequelae of suppurative hip arthritis are mostly young, cementless THA is preferred for a better long-term survivorship.ConclusionTHA is an effective method for the sequelae of suppurative hip arthritis, but the operation is difficult and has relative high complication rate. Surgeons should have full understanding.
ObjectiveTo provide references for postoperative analgesia treatment for cirrhotic patients with bone fracture. MethodsOne elderly patient with liver cirrhosis and fracture was admitted to our hospital on July 9, 2013. We obtained medical evidences by searching databases and regulated the best treatment after evaluating the patient's comprehensive conditions. And then, the whole treatment strategy was fully implemented. Finally, the consequent results were evaluated. ResultsWe identified 22 relevant articles including one clinical guideline, three cochrane reviews, five systematic reviews, seven small sample randomized controlled trials, one high quality observational study, and five quantitative reviews. We found that opioid analgesics utilization combined with non-opioid analgesics could not only reduce the occurrence of opioid drug adverse reactions, but increase analgesia safety. Cox-2 inhibitors could be used as the first choice of non-opioid drugs due to the less adverse reaction and better analgesic effectiveness. ConclusionFor femur fracture patients with liver cirrhosis, treatment decision based on evidence-based medicine is more scientific, which can ensure maximum benefit for the patients.
ObjectiveTo review the perioperative blood management (PBM) of total knee arthroplasty (TKA) and total hip arthroplasty (THA).MethodsRecent researches on PBM for TKA and THA were comprehensively read and summarized. Then the advantages and disadvantages of various measures together with the clinical experience of West China Hospital of Sichuan University were evaluated from three aspects, including optimizing hematopoiesis, reducing blood loss and blood transfusion, which could provide a basis for clinical selection.ResultsThere are many PBM methods in TKA and THA, among which the optimization of hematopoiesis mainly includes the application of perioperative iron and erythropoietin. Measures to reduce bleeding include the use of tourniquet, intraoperative controlled hypotension, and perioperative antifibrinolytic agents. Autologous blood transfusion includes preoperative autologous blood donation, hemodilution and cell salvage. Allogeneic blood transfusion is the ultimate treatment for anemia. The application of erythropoietin combined with iron therapy for blood mobilization before surgery together with intraoperative controlled hypotension for bleeding control and the multiple use of tranexamic acid can achieve satisfactory clinical results.ConclusionIn the perioperative period of TKA and THA, single or multiple use of different blood management measures should be considered carefully according to the physical and economic conditions of patients individually, so as to reduce the blood loss and allogeneic blood transfusion optimally, and finally accelerate the recovery of patients.
Objective To assess the effectiveness and safety of collagenase for intervertebral disk hernia, to facilitate the rational selection of the most appropriate therapy. Methods We searched the following electronic databases: Medline (1966 to May 2006), EMbase (1966 to May 2006), The Cochrane Library (Issue 2, 2006), CRD (Center for Reviews and Dissemination, York University), CBM (1978 to May 2006), CNKI (1994 to 2006), and VIP (1989 to 2006). RCTs or quasi-RCTs were included. RevMan 4.2 was used for statistical analysis. Results Six RCTs and one quasi-RCT involving 829 participants were included. One study showed that the short-term effective rate was similar between chemonucleolysis (CNL) and percutaneous laser dise decompression (PLDD), but the long-term effective rate of PLDD was superior to that of CNL (RR 0.35, 95%CI 0.13 to 0.96). One study revealed that the short- and long-term effective rate of CNL were higher than those of placebo (Plt;0.05). Two studies comparing collagenase vs chymopaain were heterogeneous: one indicated that chymopapain was superior to collagenase according to ITT analysis (Plt;0.05); but the other revealed no significant difference among the high- and low-dose collagenase groups and chymopapain group (Pgt;0.05). One trial showed that the effective rate between collagenase and automated percutaneous lumbar discectomy (APLD) was not significantly different (Pgt;0.05). The overall results of CNL vs Triamcinolone Acetonide showed no significant difference, but significant difference was found among patients with different types of intervertebral disk hernia. One study showed that CNL was superior to Prednisolone. Three studies reported adverse effects, mainly involving pain, neurologic deficit, cauda equina syndrome and allergic reaction amongst others. Conclusions No adequate evidence shows which therapy is more effective for intervertebral disk hernia. More high-quality trials are required.
ObjectiveTo investigate the safety and efficacy of sequential use of tranexamic acid (TXA) in the perioperative period of half hip replacement for femoral neck fracture in the elderly.MethodsPatients who underwent hemiarthroplasty due to femoral neck fracture in Meishan Traditional Chinese Medicine Hospital from January 2016 to October 2018 were retrospectively included. According to the use of TXA during the perioperative period, the patients were divided into group A (no use of TXA), group B (TXA use on the day of surgery), and group C (sequential therapy). The perioperative blood loss, blood transfusion rate and incidence of deep vein thrombosis (DVT) in the 3 groups were recorded and counted.ResultsA total of 113 patients were included, and 99 patients were finally included (31 in group A, 36 in group B, and 32 in group C). There were no statistically significant difference in age, sex, body mass index, hemoglobin (Hb) at admission, hematocrit at admission, blood volume, or blood transfusion among the three groups. The differences in total blood loss (F=43.613, P<0.001), preoperative blood loss (F=4.746, P=0.011), preoperative Hb (F=6.220, P=0.003), maximum Hb change (F=18.913, P<0.001), and postoperative length of hospital stay (F=43.511, P<0.001) among the three groups were statistically significant. There was no DVT of the lower extremities or pulmonary embolism found in the three groups. The differences in preoperative blood loss and preoperative Hb were not statistically significant between group A and group B. The difference in postoperative length of hospital stay was not statistically significant between group B and group C. The differences in other indexes between all the pairs of the three groups were statistically significant (P<0.05).ConclusionUsing TXA early after femoral neck fracture and sequentially to the day of surgery can reduce perioperative blood loss, including hidden blood loss before surgery and blood loss during and after the operation, which is beneficial to patients’ postoperative recovery without increasing the risk of DVT.
ObjectiveTo evaluate the safety and effectiveness of total hip arthroplasty (THA) in patients with hypothyroidism.MethodsSixty-three patients with hypothyroidism (hypothyroidism group) and 63 euthyroid patients without history of thyroid disease (control group) who underwent primary unilateral THA between November 2009 and November 2018 were enrolled in this retrospective case control study. There was no significant difference between the two groups in gender, age, body mass index, hip side, reason for THA, American Society of Anesthesiology (ASA) classification, preoperative hemoglobin (Hb) level, and preoperative Harris score (P>0.05). The perioperative thyroid stimulating hormone (TSH) and thyroxine (T4) levels, the hypothyroidism-related and other complications during hospitalization, the decrease in Hb, perioperative total blood loss, blood transfusion rate, length of hospital stays, and 90 days readmissions rate in the two groups were recorded and evaluated. The periprosthetic joint infection, aseptic loosening of the prosthesis, and hip Harris score during follow-up were recorded.ResultsThe differences in the TSH and T4 of hypothyroidism group between pre- and 3 days post-operation were significant (P>0.05) and no hypothyroidism-related complications occurred after THA. The decrease in Hb and perioperative total blood loss in the hypothyroidism group were significantly higher than those in the control group (P<0.05), but there was no significant difference between the two groups in terms of transfusion rate, length of hospital stays, and 90 days readmission rates (P>0.05). No significant difference in the rate of complications (liver dysfunction, heart failure, pulmonary infection, urinary infection, and wound complication) between the two groups was found (P>0.05) except for the rate of intramuscular vein thrombosis which was significantly lower in the hypothyroidism group, and the rate of postoperative anemia which was significantly higher in the hypothyroidism group (P<0.05). The two groups were followed up 1.0-9.9 years (mean, 6.5 years). At last follow-up, Harris score in both groups were significantly higher than those before operation (P<0.05). An increase of 39.5±12.3 in hypothyroidism group and 41.3±9.3 in control group were recorded, but no significant difference was found between the two groups (t=0.958, P=0.340). During the follow-up, 1 case of periprosthetic joint infection occurred in the hypothyroidism group, no loosening or revision was found in the control group.ConclusionWith the serum TSH controlled within 0.5-3.0 mU/L and T4 at normal level preoperatively, as well as the application of multiple blood management, hypothyroid patients can safely go through THA perioperative period and effectively improve joint function, quality of life, and obtain good mid-term effectiveness.
ObjectiveTo explore the short-term effectiveness of domestic robot-assisted total knee arthroplasty (RATKA) conducted by a prospective randomized controlled trial.MethodsPatients who were scheduled for primary unilateral TKA between October 2020 and December 2020 were eligible in this randomized controlled trial. According to the random number table method, they were allocated to the traditional TKA group and the RATKA group [application of the Yuanhua robotic-assisted TKA (YUANHUA-TKA) system during operation]. A total of 63 patients met the selection criteria were enrolled in the study, of which 3 cases voluntarily withdrew from the trial. And finally 60 cases were enrolled for analysis; of which 28 cases were in the RATKA group and 32 cases were in the traditional TKA group. There was no significant difference in gender, age, body mass index, American Society of Anesthesiologists (ASA) classification, duration of osteoarthritis, surgical side, and preoperative knee visual analogue scale (VAS) resting and motion scores, joint range of motion (ROM), Knee Society Score (KSS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) pain, stiffness, and function scores, hip-knee-ankle angle (HKA) deviation (P>0.05). The operation time and intraoperative blood loss of the two groups were recorded. Knee joint VAS resting and motion scores, ROM, KSS scores, and WOMAC pain, stiffness, and function scores were used to evaluate the knee joint function and pain. Gait analysis (flexion and extension angle) was conducted at 3 months after operation. The full length X-ray films of lower limbs and anteroposterior and lateral X-ray films of knee joint were taken. The HKA deviation, lateral tibia component (LTC), frontal femoral component (FFC), frontal tibia component (FTC), and lateral femoral component (LFC) measured on the X-ray films were used to evaluat the lower limb alignment and prosthesis position.ResultsThe operations of the two groups completed successfully; the incisions healed by first intention after operation, and no complications related to the operation occurred. The operation time of the RATKA group was significantly longer than that of the traditional TKA group (t=12.253, P=0.001), and there was no significant difference in intraoperative blood loss between the two groups (t=3.382, P=0.071). All patients were followed up 3 months. At 3 months after operation, the knee joint VAS resting and motion scores, ROM, KSS scores, and WOMAC pain, stiffness, and function scores improved significantly when compared with preoperatively in the two groups (P<0.05); there was no significant difference of pre- and post-operative indicators between the two groups (P>0.05). The gait analysis showed that the flexion and extension angle in the RATKA group was significantly bigger than that in the traditional TKA group (t=9.469, P=0.003). X-ray films reexamination at 3 months after operation showed that the prostheses in the two groups were in good positions, and there was no adverse events such as prosthesis loosening or sinking. There were significant differences in the HKA deviation between pre- and post-operation in the two groups (P<0.05), but the difference of pre- and post-operative HKA deviation between the two groups was not significant (t=1.254, P=0.267). There was no significant difference in FFC, FTC, and LFC between the two groups (P>0.05); the LTC was significantly smaller in the RATKA group than in the traditional TKA group (t=17.819, P=0.000), which was closer to the ideal value.ConclusionYUANHUA-TKA system can improve the accuracy of osteotomy and the prosthesis placement as well as the lower limb alignment. Its short-term effectiveness can be promised, but long-term effectiveness needs to be further studied.
Objective To study the analgesic effect of a new “cocktail” of local infiltration analgesia (LIA) with Deprosone after total hip arthroplasty (THA). Methods In a prospective randomized controlled study, 100 patients with hip joint disease requiring unilateral primary THA in West China Hospital of Sichuan University between January 2018 and December 2018 were enrolled and randomly divided into observation group and control group, with 50 cases in each group. There was no significant difference in age, gender, operative side, disease type, body mass index, American Society of Anesthesiologists (ASA) classification, preoperative rest and activity visual analogue scale (VAS) score, hip Harris score (HHS), quality of life scale (SF-12) score, and other general data between the two groups (P>0.05). The patients in the observation group were treated with a new “cocktail” LIA around the hip joint before suturing the incision, and the drug formula was ropivacaine 200 mg, Diprospan 1 mL, morphine 10 mg, and added normal saline to 80 mL; the patients in the control group were not treated with LIA. The operation time, postoperative hospital stay, the amount of morphine used during hospitalization, and the range of motion of hip joint at discharge were recorded, and the complications were counted. The VAS score at rest and activity, HHS score, and SF-12 score [physiological score (PCS) and psychological score (MCS)] of the hip joint were recorded before and after operation, and the postoperative analgesic effect and the recovery of hip joint function were evaluated. Results There was no significant difference in the operation time between the two groups (P>0.05), and the postoperative hospital stay in the observation group was significantly shorter than that in the control group (P<0.05). The postoperative morphine consumption in the observation group was significantly less than that in the control group (P<0.05), and the total morphine consumption in the observation group was less than that in the control group during hospitalization, but the difference was not significant (P>0.05). Patients in both groups were followed up to 6 months after operation. The resting VAS scores of the observation group were significantly lower than those of the control group at 2, 6, 12 hours after operation and in the morning and afternoon of the first day after operation, and the active VAS scores of the observation group were significantly lower than those of the control group at 6, 12 hours after operation and in the morning of the first day after operation, and the differences were significant (P<0.05). There was no significant difference in the resting and active VAS scores between the two groups on the day of discharge and at 3 and 6 months after operation (P>0.05). At discharge, the flexion range of motion of hip joint in the observation group was significantly greater than that in the control group (P<0.05), but there was no significant difference in the abduction range of motion of hip joint between the two groups (P>0.05). There was no significant difference in HHS score and SF-12 score between the two groups at 3 and 6 months after operation (P>0.05). There was no significant difference in analgesic satisfaction and functional satisfaction between the two groups at last follow-up (P>0.05). There was no complication such as skin pruritus, superficial and deep infection of incision, skin necrosis, deep venous thrombosis of lower extremity, and pulmonary embolism in both groups. There was no significant difference in the incidence of complications such as nausea and vomiting, urine retention, fat liquefaction of incision, local hematoma, and large fluctuation of blood sugar between the two groups (P>0.05). ConclusionThe new “cocktail” LIA with Diprospan can effectively reduce the early postoperative pain of THA, reduce the dosage of opioids, shorten the length of hospital stay, and is conducive to the early functional rehabilitation of patients.
Objective To systematically review the effectiveness and safety of total hip arthroplasty (THA) vs. total hip resurfacing arthroplasty (THRA) in patients with osteoarthritis of the hip joint. Methods We electronically searched databases including PubMed, The Cochrane Library (Issue 3, 2012), EMbase, PloS, national institutes of clinical test library of the United States, national joint replacement registration network of Australia, British national joint registration network, British orthopaedic association network (BOA), Canada orthopaedic association (COA), American Academy of Orthopedic Surgeons network (AAOS), German Institute of Medical Documentation and Information network (DIMDI) for randomized controlled trials (RCTs) on the comparison between THA and THRA for osteoarthritis of the hip joint from inception to November, 2012. References of the included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the quality of the included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results Six RCTs (10 articles) involving 518 cases of surgery (THA: n=259; THRA: n=259) were identified. The risk of bias of 8 articles was moderate and that of the other 2 articles was low. The results of meta-analysis showed that, compared to THRA, THA brings greater improvements of femoral offset within 2 years after surgery (MD=6.60, 95%CI 5.53 to 7.68, P=0.25). There were no significant differences between the two groups in Merle d’Aubigné Postel, WOMAC score, UCLA score, SF-36 Health Survey Questionnaire, walking speed, step length, walking cadence, postoperative leg length discrepancy, and complication rates. All these conclusions are based on early postoperative results. Conclusion Current evidence shows that, THA brings greater improvements of femoral offset than THRA, and no significant differences between the two groups were found in the other indicators.
