Project description:Treatment of severely destroyed rheumatoid wrists with total wrist arthroplasty or total wrist arthrodesis relies on patient and surgeon preferences rather than rigorous prospective outcomes data. The purpose of this study is to develop a decision analytic model of arthroplasty and arthrodesis in rheumatoid arthritis (RA) using utility values obtained from a random sample of hand surgeons.A utility survey using a time trade-off design was administered to 175 members of the American Society for Surgery of the Hand. Based on the results of the survey, the utility values that surgeons assign to health states associated with arthroplasty and arthrodesis and their complications were calculated. By combining utility values with complication rates in the published literature, we developed a decision tree to calculate the expected quality-adjusted life years (QALYs) for each procedure compared to living with a painful RA wrist.Based on surgeon preferences, living for 30 years with a painful, poorly functioning RA wrist (utility = 0.54) is associated with 16.2 QALYs. Treatment with arthroplasty (utility = 0.85) is associated with 25.5 QALYs, a gain of 9.3 QALYs over nonsurgical management. Arthrodesis (utility = 0.82) is associated with 24.6 QALYs, a gain of 8.4 QALYs over nonsurgical management. Arthroplasty is associated with a small incremental increase in QALYs (0.9) compared to arthrodesis.Based on utility scores, hand surgeons feel that living with a painful, poorly functioning RA wrist for 30 years is worth approximately half as many years with a painless, well-functioning wrist. The outcomes for arthroplasty and arthrodesis are valued more than nonsurgical management. On the basis of its higher expected gain in QALYs, arthroplasty should be the preferred treatment. The minimal increase in utility for arthroplasty over arthrodesis suggests however, that surgeons do not view arthroplasty as superior to arthrodesis.Economic and decision analysis IV.

Project description:Hip fusion takedown to total hip replacement is a challenging operation. Neck osteotomy and acetabular component placement are technically demanding and often require fluoroscopic guidance. Robotic arm-assisted total hip arthroplasty enhances accuracy of preoperative planning and provides navigated guidance for neck osteotomy and haptic guidance on acetabular reaming and cup implantation. Fluoroscopic guidance is replaced by real-time navigation and on-screen data. This article describes how robotic arm assistance can simplify this complex operation.

Project description:BackgroundIt is controversial whether or not the carpometacarpal joint (CMCJ) should be included in total wrist arthrodesis (TWA). Complications commonly occur at this site and studies examining its inclusion and exclusion are conflicting. A randomised clinical trial comparing wrist arthrodesis with CMCJ arthrodesis and spanning plate to wrist arthrodesis with CMCJ preservation and non-CMCJ spanning plate has not been performed.MethodA single centre randomised clinical trial including 120 adults with end-stage isolated wrist arthritis will be performed to compare TWA with and without the CMCJ included in the arthrodesis. The primary outcome is complications in the first post-operative year. Secondary outcomes are Disabilities of the Arm, Shoulder and Hand (DASH) score, Patient Rated Wrist Evaluation (PRWE) and grip strength measured at 1, 2 and 5 years. Late complications, return to work and satisfaction will also be recorded.DiscussionIt is unknown whether the CMCJ should be included in TWA. This trial will contribute to an improved understanding of optimal management of the CMCJ in total wrist arthrodesis.Trial registrationThis trial was prospectively registered with the Australia New Zealand Clinical Trials Registry with identifying number ACTRN12621000169842 on the 16th February 2021.

Project description:Surgical management of end-stage rheumatoid wrists is a contentious topic. The standard surgical treatment has traditionally been wrist arthrodesis. Wrist arthroplasty, however, offers an alternative that preserves some wrist motion. A systematic review of MEDLINE, EMBASE and CENTRAL databases was conducted. Data from 23 studies representing 343 cases of wrist arthrodesis and 618 cases of wrist arthroplasty were included. Complication rates were 17% for arthrodesis and 19% for arthroplasty, and both procedures were effective at alleviating pain and improving grip strength. Functional assessment by Disabilities of the Arm, Shoulder, and Hand and Patient-Related Wrist Evaluation of arthroplasty patients revealed clinically meaningful functional improvement compared with preoperative measurements. In contrast to previously published findings both procedures demonstrated comparable complication rates. While this can be speculated to be from advancements in prosthetics, robust long-term follow-up data on wrist arthroplasty are not available yet.

Project description:Total knee arthroplasty (TKA) in the setting of previous hip fusion is rare with a paucity of evidence in the orthopaedic literature. Traditionally, TKA is performed supine, with the aid of knee-positioning devices allowing for hip flexion and range of motion of the knee to facilitate ease of surgical intervention. However, TKA using traditional positioning would not be possible in the presence of ipsilateral hip arthrodesis preventing hip motion. This case report describes a TKA performed for a 72-year-old woman with end-stage osteoarthritis of the right knee, ipsilateral hip arthrodesis, and leg-length discrepancy as the sequelae of slipped capital femoral epiphysis. We describe novel surgical positioning to be used to facilitate TKA in the absence of ipsilateral hip motion with bed modifications and the use of an extremity positioning device.

Project description:BackgroundAlthough the results of hip arthrodesis compare favorably with those of total hip arthroplasty (THA) in younger patients, long-term consequences such as osteoarthritis of the neighboring joints may necessitate conversion of the arthrodesis to THA.Questions/purposesThe purpose of the present study is to assess mid-term clinical outcome and self-perceived improvement in patients who underwent conversion at our department. Secondary aims were incidence of complications and association between patient characteristics and characteristics of the fusions with the outcome of the procedure.Patients and methodsThe study sample comprised 21 cases in 20 patients. Minimum follow-up was 3 years (mean, 8?±?6.5 years) in 20 cases. Thirteen patients had surgical hip fusions and 7 (8 hips) had nonsurgical fusions. Mean age at the time of conversion was 58.5 years.ResultsNineteen out of 21 cases had functioning implants at the latest follow-up visit. According to the Merle d'Aubigné scale, outcome was considered excellent, very good, or good in 15 cases. Lower back pain was reduced in all patients. All but two patients were satisfied after the conversion. The main complications observed included incomplete removal of bone block, intra-operative fractures, dislocation and damage to the femoral artery. Time to conversion and type of fusion had no significant correlation with the clinical outcome.ConclusionsConversion THA is a challenging but successful procedure according to the mid-term clinical outcome observed. Our study suggests that, prognostic factors should be used with caution when establishing indications and post-surgical expectations.

Project description:Background and Literature Review Periprosthetic osteolysis (PPO) after second- or third-generation total wrist arthroplasty (TWA), with or without evident loosening of the implant components, has previously been reported in the literature, but rarely in a systematic way. Purpose The purpose of this study was to analyze the prevalence, location, and natural history of PPO following a TWA and to determine whether this was associated with prosthetic loosening. Patients and Methods We analyzed 44 consecutive cases in which a RE-MOTION TWA (Small Bone Innovations Inc., Morrisville, PA, USA) had been done. Results We found significant periprosthetic radiolucency (more than 2 mm in width) at the radial component side in 16 of the cases and at the carpal component side in 7. It developed gradually juxta-articularly around the prosthetic components regardless of the primary diagnosis, and seemed to stabilize in most patients after 1-3 years. In a small percentage of the patients, the periprosthetic area of bone resorption was markedly larger. In general, radiolucency was not related to evident loosening of the implant components, and only five carpal components and one radial had subsided or tilted. Conclusion Periprosthetic loosening is frequent following a TWA. In our series it was not necessarily associated with implant loosening and seemed to stabilize within 3 years. Close and continued observation is, however, recommended. Level of Evidence Therapeutic IV.

Project description:The application of tranexamic acid (TXA) in total joint arthroplasty has dramatically improved peri-operative blood management. In light of these benefits, a study by Huang et al., "Intravenous and Topical Tranexamic Acid Alone Are Superior to Tourniquet Use for Primary Total Knee Arthroplasty," evaluates the need for continued use of the intra-operative tourniquet, which remains a routine practice with documented benefits and adverse effects. This review evaluates the study's design and critically interprets its findings for clinical practice. Through a prospective, randomized trial, Huang et al. demonstrated that among selected patients undergoing primary total knee arthroplasty, the use of a tourniquet results in no reduction in blood loss beyond that provided by TXA alone. Moreover, the use of TXA without a tourniquet led to improved early clinical outcomes such as reduced post-operative swelling, improved knee range of motion at discharge, and enhanced patient satisfaction. As medicine is practiced in an increasingly value-driven environment, this study provides a useful method for evaluating the utility of commonly used interventions. Its findings highlight the need for future investigations into the optimal administration of TXA in total knee arthroplasty.

Project description:Background Severely destroyed posttraumatic wrists are usually treated by partial or total wrist fusion or proximal row carpectomy. The indications for and longevity of total wrist arthroplasty (TWA) are still unclear. Case Description The aim of this study was to analyze a series in which one last-generation total wrist arthroplasty was used as a salvage procedure for wrists with severe arthritis due to traumatic causes. The data were prospectively recorded in a web-based registry. Seven centers participated. Thirty-five cases had a minimum follow-up time of 2 years. Average follow-up was 39 (24-96) months. Pain had improved significantly at follow-up, mobility remained unchanged. The total revision rate was 3.7%, and the implant survival was 92% at 4-8 years. Literature Review Very few studies have described specific results after TWA in posttraumatic cases and almost none using classical "third-generation" implants. The number of cases and the follow-up in the published series are small. Clinical Relevance Although painful posttraumatic wrists with severe joint destruction can be salvaged by partial or total fusion, we found that, evaluated at short- to midterm, total wrist arthroplasty can be an alternative procedure and gives results that are comparable to those obtained in rheumatoid cases. Level IV Case series.
