RESUMEN

The epidemiological data on osteogenesis imperfecta (OI) in Asia is limited. This study, representing the first comprehensive epidemiological investigation on OI in Taiwan, reveals high medical resource utilization and underscores the importance of early diagnosis to enhance care quality. INTRODUCTION: This study examines osteogenesis imperfecta, a hereditary connective tissue disorder causing pediatric fractures and limb deformities, using a nationwide database from Taiwan to analyze clinical features and medical burden. METHODS: The study identified validated OI patients from the Catastrophic Illness Registry in the National Health Insurance Research Database from 2008 to 2019. Demographic data and medical resource utilization were analyzed. A multivariate Cox model assessed the influence of sex, validation age, and comorbidities. RESULTS: 319 OI patients (M/F = 153/166) were identified, with 58% validated before age 20. Prevalence and incidence were 0.8-1.3/100,000 and 0.02-0.09/100,000, respectively, with higher rates in the pediatric demographic. In the study period, 69.6% of the patients had admission history, primarily to pediatric and orthopedic wards. The median admission number was 3, with a median length of stay of 12 days and a median inpatient cost of approximately 3,163 USD during the period. Lower limb fractures were the main reason for hospitalization. 57% of OI patients received bisphosphonate treatment. The leading causes of mortality were OI-related deaths, neurovascular disease, and cardiovascular disease. The median age of validation in the non-survival group was significantly higher compared to the survival group (33 vs. 14 years), and patients validated during childhood required more inpatient fracture surgeries than those validated during adulthood. CONCLUSION: This study provides comprehensive real-world evidence on the clinical characteristics and high medical resource utilization of OI patients in a low prevalence region like Taiwan. Early diagnosis is crucial for improving care quality and enhancing health outcomes.

RESUMEN

BACKGROUND: The incidence of unplanned emergency department (ED) visits following revision total joint arthroplasty is an indicator of the quality of postoperative care. The aim of this study was to investigate the incidences, timings, and characteristics of ED visits within 90 days after revision total joint arthroplasty. METHODS: A retrospective review of 457 consecutive cases, including 254 revision total hip arthroplasty (rTHA) and 203 revision total knee arthroplasty (rTKA) cases, was conducted. Data regarding patient demographics, timings of the ED encounter, chief complaints, readmissions, and diagnoses indicating reoperation were analyzed. RESULTS: The results showed that 41 patients who had rTHA (16.1%) and 14 patients who had rTKA (6.9%) returned to the ED within 90 days postoperatively. The incidence of ED visits was significantly higher in the rTHA group than in the rTKA group (P = .003). The most common surgery-related complications were dislocation among rTHA patients and wound conditions among rTKA patients. Apart from elevated calculated comorbidity scores, peptic ulcer in rTHA patients and cerebral vascular events and chronic obstructive pulmonary disease in rTKA patients might increase chances of unplanned ED visits. Patients who had ED visits showed significantly higher mortality rates than the others in both rTHA and rTKA cohorts (P = .050 and P = .008, respectively). CONCLUSIONS: The ED visits within 90 days are more common after rTHA than after rTKA. Patients in both ED visit groups after rTHA and rTKA demonstrated worse survival. Efforts should be made to improve quality of care to prevent ED visits.

RESUMEN

This study aimed to assess the impact of drug adherence and treatment duration for denosumab on mortality risk after hip fracture surgery. Lower all-cause mortality risk was associated with drug intervals of 7 months or less and longer treatment duration. The study highlights the importance of proper denosumab administration. PURPOSE: Prescription of anti-osteoporotic medications (AOMs) after osteoporotic hip fracture may increase bone mineral density (BMD) and decrease mortality risk. However, few studies have been conducted on drug adherence and treatment duration for denosumab, a popular choice among AOMs. This study aimed to assess the impact of denosumab adherence and treatment duration on the mortality risk of hip fracture patients after surgery. METHODS: We conducted a cohort study using nationwide population data from National Health Insurance Research Database (NHIRD) in Taiwan. Patients newly diagnosed with osteoporosis and hip fracture between 2008 and 2019 who used denosumab after surgery were included. We assessed drug adherence, treatment duration, and other parameters associated with patient outcomes. RESULTS: A total of 21,316 patients diagnosed with osteoporotic hip fractures were included. Compared with a > 7-month drug interval for denosumab, an interval of ≤ 7 months led to lower all-cause mortality risk (hazard ratio (HR): 0.60, 95% confidence interval (CI): 0.57 ~ 0.64). Patients with denosumab treatment for over 1, 2, and 3 years had lower all-cause mortality risk (HR&CI: 0.68 (0.64 ~ 0.73), 0.48 (0.43 ~ 0.53), 0.29 (0.26 ~ 0.33)) than those with treatment duration < 1 year. Analysis after excluding short-term death yielded similar results. Analysis of causes of death also showed that good adherence and longer duration were associated with reduced mortality due to cancer and cardiovascular disease. CONCLUSION: Better drug adherence and longer duration of denosumab treatment are associated with lower all-cause mortality risk among hip fracture patients after surgery. Our study highlights the benefits of a proper time interval of denosumab administration. These findings provide important insight into management of osteoporotic hip fractures and may inform clinical practice and development of guidelines.

RESUMEN

PURPOSE: To evaluate the short-term outcomes of genicular artery embolization (GAE) for knee osteoarthritis (OA) with and without bone marrow lesion (BML) and/or subchondral insufficiency fracture of the knee (SIFK). MATERIALS AND METHODS: This single-institution prospective observational pilot study analyzed 24 knees in 22 patients with mild to moderate knee OA, including 8 knees without BML, 13 knees with BML, and 3 knees with both BML and SIFK. The area and volume of BMLs on magnetic resonance images were measured before and after GAE. Baseline and postoperative pain and physical function were assessed using the visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). RESULTS: GAE significantly reduced the BML area and volume 3 months after embolization in the knees with BML (both P < .0005). GAE significantly decreased the VAS scores at 3 and 6 months after embolization in patients without BML (both P = .04) and those with BML (both P = .01). GAE also lowered the WOMAC scores 3 months after embolization in patients without and with BML (P = .02 and P = .0002, respectively). However, GAE did not significantly alter the BML area and volume (both P = .25), VAS scores (P = 1.00), and WOMAC scores (P = .08) in patients with BML and SIFK at 3 months after GAE. CONCLUSIONS: This observational pilot study suggested that GAE effectively reduces the BML area and volume and improves pain and physical function in patients with knee OA accompanied by BML but is inefficacious in those with both BML and SIFK.

RESUMEN

BACKGROUND: Real-world cost and effectiveness analyses of the anti-osteoporosis medications (AOM) using a nationwide database in Asia were limited. The aim of this study was to evaluate the cost and effectiveness of AOMs therapy under the reimbursement of National Health Insurance in Taiwan. METHODS: Using Taiwan's National Health Insurance Research Database, patients who had hospitalization due to incident hip fractures with related operation between 2008 and 2017 were identified as our study population. Patients who initiated AOMs within 1 year post incident hip fracture were matched with those did not according to the propensity score. The direct medical cost and subsequent fracture within three years were estimated. Statistically significant differences of risk for subsequent fracture between the AOM and non-AOM groups were estimated using the COX proportional hazards model. All costs were presented as New Taiwan Dollars (NTD). RESULTS: There were 27,357 new hip fracture patients who initiated AOMs, and 76% of them were women with a mean age of 77.7 years. Among patients ages ≥70 who encountered hip fractures, those who initiated AOMs experienced fewer non-vertebral fractures (HR = 1.07 (1.02-1.13), p = 0.0114 for those ages 70-79 years old; HR = 1.11 (1.06-1.17), p < 0.0001 for those ages ≥80 years) and mortality (HR = 1.18 (1.14-1.22), p < 0.0001 for those ages 70-79; HR = 1.20 (1.16-1.23), p < 0.0001) within 3 years post incident fracture; meanwhile, consuming fewer medical resources in the national insurance healthcare system. (Increment cost = -16011.2 NTD, p = 0.0248 for those ages 70-79; Increment cost = -17257.9 NTD, p = 0.0032 for those ages ≥80 years) CONCLUSION: Overall, under Taiwan's national health insurance, the use of AOMs is cost-saving, especially in the population aged ≥70 years. The finding of this research was valuable for policymakers in considering healthcare policy promotion and resource allocation in the future.

RESUMEN

BACKGROUND: Osteoporotic vertebral fractures may predict the future occurrence of fractures and increase mortality. Treating underlying osteoporosis may prevent second fractures. However, whether anti-osteoporotic treatment can reduce the mortality rate is not clear. The aim of this population study was to identify the degree of decreased mortality following the use of anti-osteoporotic medication after vertebral fractures. METHODS: We identified patients who had newly diagnosed osteoporosis and vertebral fractures from 2009 to 2019 using the Taiwan National Health Insurance Research Database (NHIRD). We used national death registration data to determine the overall mortality rate. RESULTS: There were 59,926 patients with osteoporotic vertebral fractures included in this study. After excluding patients with short-term mortality, patients who had previously received anti-osteoporotic medications had a lower refracture rate as well as a lower mortality risk (hazard ratio (HR): 0.84, 95% confidence interval (CI): 0.81-0.88). Patients receiving treatment for more than 3 years had a much lower mortality risk (HR: 0.53, 95% CI: 0.50-0.57). Patients who used oral bisphosphonates (alendronate and risedronate, HR: 0.95, 95% CI: 0.90-1.00), intravenous zoledronic acid (HR: 0.83, 95% CI: 0.74-0.93), and subcutaneous denosumab injections (HR: 0.71, 95% CI: 0.65-0.77) had lower mortality rates than patients without further treatment after vertebral fractures. CONCLUSION: In addition to fracture prevention, anti-osteoporotic treatments for patients with vertebral fractures were associated with a reduction in mortality. A longer duration of treatment and the use of long-acting drugs was also associated with lower mortality.

RESUMEN

Osteoporosis greatly increases the risk of fractures. Osteoporotic fractures negatively impact quality of life, increase the burden of care, and increase mortality. Taiwan is an area with a high prevalence of osteoporosis. This updated summary of guidelines has been developed by experts of the Taiwan Osteoporosis Association with the intention of reducing the risks of osteoporotic fractures and improving the quality of care for patients with osteoporosis. The updated guidelines compile the latest evidence to provide clinicians and other healthcare professionals with practical recommendations for the prevention, diagnosis, and management of osteoporosis under clinical settings in Taiwan.

RESUMEN

BACKGROUND: Previous epidemiological researchers have used various algorithms to identify a second hip fracture; however, there has been no validation of these algorithms to date. This study aimed to verify existing algorithms for identifying second hip fracture under the International Classification of Diseases diagnostic coding systems. Furthermore, we examined the validity of two newly proposed algorithms that integrated the concept of periprosthetic fractures and laterality of the ICD-10 coding system. METHODS: Claims data of patients hospitalized for hip fracture from National Taiwan University Hospitals between 2007 and 2020 were retrieved. Hip fracture was confirmed by 2 orthopaedic surgeons with medical records and imaging data as gold standards. The validity of 9 existing and 2 newly proposed algorithms for identifying second hip fracture was evaluated. RESULTS: The positive predictive value (PPV) range between 84% and 90% in existing algorithms for identifying second hip fractures. Noteworthy, the longer time interval for discrimination resulted in slightly increased PPV (from 87% to 90%), while decreased sensitivity noticeably (from 87% to 72%). When considering the information about periprosthetic fracture, the PPV increased to 91% without diminished sensitivity. The PPV of the newly proposed ICD-10-specific algorithm was 100%. CONCLUSION: Algorithms integrated clinical insights of periprosthetic fractures and laterality concept of ICD-10 coding system provided satisfactory validity and help precisely define second hip fracture in future database research.

RESUMEN

BACKGROUND: Postoperative delirium in patients who have hip fractures may lead to poor outcomes. This study aimed to determine perioperative risk factors and clinical outcomes of postoperative delirium in patients undergoing hip bipolar hemiarthroplasty for displaced femoral neck fractures. METHODS: Among 1,353 patients who underwent hemiarthroplasty at our institution during 2013-2021, we identified 78 patients with postoperative delirium diagnosed with the confusion assessment method. The mean delirium duration was 28 hours (range: 15-520). We also included 1:2 sex- and age-matched patients who did not have postoperative delirium after the same surgery as a matching cohort for comparison. Patient comorbidities, perioperative data, delirium occurrence, and outcomes were collected for analyses. RESULTS: A Charlson Comorbidity Index (CCI) score ≥6 (odds ratio (OR): 2.08, P = .017), nighttime surgery (OR: 3.47, p =<.001), surgical delays (OR: 1.01, P = .012), preoperative anemia (OR: 2.1, P = .012), and blood transfusions (OR: 2.47, P = .01) may increase the risk of postoperative delirium. The presentation of delirium was associated with sepsis (OR: 3.77, P = .04), longer hospital stays (P < .001), higher 1-year mortality (OR: 3.97, P = .002), and overall mortality (OR: 2.1, P = .02). CONCLUSION: Postoperative delirium predicted poor outcomes. Our results emphasized the importance of early identification of patients at risk and optimization of the medical conditions before and after surgery.

RESUMEN

BACKGROUND: Two-stage exchange arthroplasty is a feasible treatment for chronic PJI (periprosthetic joint infection) of total hip arthroplasty (THA). However, there are large numbers of patients who are unable to ultimately receive reimplantation after resection arthroplasty owing to uncontrolled infection and multiple comorbidities. The purpose of the current study was to identify patient-related risk factors and reasons for being unable to undergo revision THA. METHODS: Individuals undergoing resection arthroplasty for chronic PJI treatment from 2013 to 2020 at our institution were retrospectively reviewed. A variety of patient comorbidities, laboratory data, isolated pathogens, and follow-up status were collected for analysis. RESULTS: A total of 84 patients (46 men and 38 women) with a 2.7 ± 2.1-year follow-up were analyzed. Thirty-eight (45.2%) patients eventually underwent revision THA, while the other 46 (54.8%) did not receive reimplantation during follow-up. The patients without receiving reimplantation had higher Charlson comorbidity index (CCI) score (3.1 ± 2.9 versus 1.2 ± 1.5; p = 0.001). Lower cumulative incidence of receiving reimplantation was observed in patients with chronic kidney disease (log-rank test, p = 0.019), anemia (p = 0.011), presence of initial fever (p = 0.030), and oxacillin-resistant strain infection (p = 0.030). The most common reasons for not receiving reimplantation were uncontrolled infection, unstable medical conditions, and death. The patients without reimplantation had a relatively higher mortality rate (log-rank test, p = 0.002). CONCLUSION: Chronic hip PJI with poor medical conditions or oxacillin-resistant strain infection decreased the chance of undergoing revision surgery. These patients had unfavourable outcomes and a higher mortality rate after resection arthroplasty.

RESUMEN

PURPOSE: Extracorporeal shockwave therapy (ESWT) has become a common practice for treating knee osteoarthritis (OA). However, the effectiveness and safety of this treatment are still questionable. This meta-analysis is aimed at determining the degree of pain reduction and functional outcome after ESWT for knee OA. METHODS: We systematically searched MEDLINE, EMBASE, and other online databases. The articles comparing the outcomes between ESWT and controls were included in the analysis. RESULTS: Nine studies with 705 patients were included. The pooled data revealed significantly lower pain scores in the ESWT groups than in the control groups within two weeks of treatment and six months after treatment (visual analogue scale, - 1.59, p = 0.0003, 95% confidence interval (CI) - 2.45 to - 0.72 at 2 weeks; - 1.12, p = 0.005, 95% CI - 1.89 to - 0.34 at 6 months). The ESWT group also had better functional outcomes four to six weeks post treatment (Western Ontario and McMaster Universities Osteoarthritis Index, - 11.96, p = 0.003, 95% CI - 19.76 to - 4.15). No rebound pain was noted for up to 12 months. CONCLUSION: Using ESWT to treat knee OA may reduce pain and improve functional outcomes. The effect may last six months to one year. More prospective studies are needed to investigate the settings for ESWT to optimize treatment results.

RESUMEN

BACKGROUND: The reported incidence of shoulder redislocation varies among different reports. This was a nationwide study to investigate the recurrence rate of shoulder dislocation after closed reduction. METHODS: We performed a cohort study to analyze the incidence of first dislocation as well as second and third repeated dislocations in a nationwide dataset from the National Health Insurance Research Database of Taiwan. Patients who had any shoulder dislocation event and received closed reduction from 2000 to 2013 were included. RESULTS: From this dataset of 1 million persons, we identified 1074 patients who had a shoulder dislocation. Of these, 210 had a second shoulder dislocation and 93 had a third shoulder dislocation. The shoulder redislocation rates were 9.4%, 12.7%, and 17.0% at 1 year, 2 years, and 5 years, respectively, after the first shoulder dislocation and 19.6% at overall follow-up. Patients in the youngest age group and male patients had higher risks of redislocation (adjusted hazard ratios, 3.28 and 1.41, respectively). The mean time to recurrence was 13.1 months. However, the patients who had a second shoulder dislocation had a shorter time to recurrence and a higher risk of redislocation (44%), with no statistical differences in risk among any age or sex groups. CONCLUSIONS: After the first shoulder dislocation, male patients and younger patients had higher shoulder redislocation rates. However, after the second shoulder dislocation, all groups shared a similar high shoulder redislocation rate regardless of age or sex. Surgical treatment should be considered for patients with multiple episodes of shoulder dislocation.

RESUMEN

AIMS AND OBJECTIVES: To examine the effects of lower extremity muscle strength training on knee function recovery and quality of life in patients who underwent total knee replacement. BACKGROUND: Patients with knee osteoarthritis after surgery experience decreased knee function that impacts their quality of life. However, patients typically lack a long-term, home-based and continuous leg exercise training method and rarely have studies explored the effects of exercise training on knee function recovery and quality of life. DESIGN: A experimental and longitudinal study design. METHODS: The simple randomised sampling (based on patients' admission priority order) was used to collect participant data. Outcome measurements included the Knee Injury and Osteoarthritis Outcome Score. Participants were randomised to receive and starting lower extremity muscle strength training before surgery (training group, n = 100) or to receive usual care (nontraining group, n = 100). Data were collected and followed up with the patients before surgery (T1) and at 2 weeks (T2), 1 month (T3), 2 months (T4) and 3 months (T5) after discharge. RESULTS: The Knee Injury and Osteoarthritis Outcome Score subscale scores showed that both groups of patients experienced knee function and quality of life decreases 2 weeks after total knee replacement, but all subscale scores gradually increased from the first month to the third month after total knee replacement. Both groups and times were significantly different, but the training group's knee function and quality of life recovered earlier and better than the nontraining group does. CONCLUSIONS: This study confirmed that lower extremity muscle strength training helps to improve quality of life and knee function in patients who undergo total knee replacement. Healthcare staff should include this training in presurgical nursing care and in patients' discharge plans as a continuous, daily rehabilitation activity at home. RELEVANCE TO CLINICAL PRACTICE: When patients are diagnosed with knee osteoarthritis and undergo surgery, a presurgical exercise education and discussion of knee function rehabilitation should be part of standard care.

RESUMEN

This study investigated the contribution of flexor muscles to the forearm through fatigue; therefore, the differences in forearm mechanisms on the pitching motion in fastball were analysed. Fifteen baseball pitchers were included in this study. Ultrasonographical examination of participants' ulnar nerve in the cubital tunnel with the elbow extended and at 45°, 90° and 120° of flexion was carried. A three-dimensional motion analysis system with 14 reflective markers attached on participants was used for motion data collection. The electromyography system was applied over the flexor carpi ulnaris, flexor carpi radialis and extensor carpi radialis muscles of the dominant arm. Flexor carpi ulnaris muscle activity showed a significant difference during the acceleration phase, with a peak value during fastball post-fatigue (P = 0.02). Significant differences in the distance between ulnar nerve and medial condyle on throwing arm and non-throwing arm were observed as the distance increased with the elbow movement from 0° to 120° of flexion (P = 0.01). The significant increase of the flexor carpi ulnaris muscle activity might be responsible for maintaining the stability of the wrist joint. The increased diameter might compress the ulnar nerve and cause several pathological changes. Therefore, fatigue in baseball pitchers still poses a threat to the ulnar nerve because the flexor carpi ulnaris and flexor carpi radialis all originate from the medial side of the elbow, and the swelling tendons after fatigue might be a key point.

RESUMEN

Objectives: Bipolar hemiarthroplasty is commonly performed to treat displaced femoral neck fractures in osteoporotic patients. This study aimed to assess the occurrence and outcomes of unplanned return visits to the emergency department (ED) within 90 days following bipolar hemiarthroplasty for displaced femoral neck fractures. Methods: The clinical data of 1322 consecutive patients who underwent bipolar hemiarthroplasty for osteoporotic femoral neck fractures at a tertiary medical center were analyzed. Data from the patients' electronic medical records, including demographic information, comorbidities, and operative details, were collected. The risk factors and mortality rates were analyzed. Results: Within 90 days after surgery, 19.9% of patients returned to the ED. Surgery-related reasons accounted for 20.2% of the patient's returns. Older age, a high Charlson comorbidity index score, chronic kidney disease, and a history of cancer were identified as significant risk factors for unplanned ED visits. Patients with uncemented implants had a significantly greater risk of returning to the ED due to periprosthetic fractures than did those with cemented implants (P = 0.04). Patients who returned to the ED within 90 days had an almost fivefold greater 1-year mortality rate (15.2% vs 3.1%, P < 0.001) and a greater overall mortality rate (26.2% vs 10.5%, P < 0.001). Conclusions: This study highlights the importance of identifying risk factors for unplanned ED visits after bipolar hemiarthroplasty, which may contribute to a better prognosis. Consideration should be given to the use of cemented implants for hemiarthroplasty, as uncemented implants are associated with a greater risk of periprosthetic fractures.

RESUMEN

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition. The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and antiresorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to antiresorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for individuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions: This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

RESUMEN

OBJECTIVES: Dynamization is a method of removing the interlocking screw(s) farthest from the fracture site for improving healing in femoral and tibial fractures that show delayed healing after static interlocking nailing. We describe a simple sonographically assisted technique for percutaneous dynamization of deep-seated impalpable screws. METHODS: Between March 2001 and March 2005, 20 dynamization procedures were completed using the developed technique under the diagnosis of delayed healing or a nonunion at a mean of 4.8 months after index surgery. After adequately positioning the involved leg, the transducer was placed on the area of the inlet of the screw. Longitudinal and transverse sonographically scanned sections, used to show the head of the screw, were then marked on the skin where the two sections intersected. After this precise marking, a small incision on the mark allowed insertion of the screwdriver and easy percutaneous removal of the screw using only local anesthesia for pain control. RESULTS: We removed 31 screws: 9 proximal femoral screws, 20 distal femoral screws, and 2 proximal tibial screws. The mean depth of the screws was 3.4 cm. The mean operation times were 1.6 minutes for the sonographic examination and 3.5 minutes for removal of one screw. No infections or morbidities were caused by the procedure. CONCLUSIONS: Sonography is an effective tool for localizing a locked screw and facilitates percutaneous removal of screws under only local anesthesia for dynamization. This method needs no special instruments and reduces the time needed for dissecting the tissue and locating the screw.

RESUMEN

BACKGROUND: Total hip arthroplasty (THA) is the treatment of choice for posttraumatic arthritis with failed internal fixation for hip fractures. However, the postoperative prognosis is not clear. QUESTIONS/PURPOSES: The primary aim of the study is to report the postoperative outcome, prognosis, and complication rates of total hip arthroplasty in posttraumatic hip arthritis after failed internal fixation of fractures around the hip. The secondary aim of the study is to report results among different fracture types around the hip. PATIENTS AND METHODS: We enrolled salvage THA patients after failed internal fixation of fractures around the hip and matched control patients undergoing primary THA for hip osteoarthritis. Subgroup analysis was performed to compare the postoperative outcomes, prognosis, and complication rates of salvage THA in posttraumatic hip arthritis after failed internal fixation of different fracture types around the hip. RESULTS: A total of 315 THAs (105 salvage THAs and 210 primary THAs) were analyzed. Patients with salvage THA had a longer operative time, lower postoperative hemoglobin (Hb) level, more Hb drop (2.2 ± 1.4 vs. 1.7 ± 1.2 gm/dl, p = 0.002), and delayed ambulation. The salvage THA group also had a higher dislocation rate within 2 months after salvage THA (9.5% vs. 1.9%, p = 0.002), reoperation rate (10.5% vs. 3.8%, p = 0.019, including debridement, open and closed reduction under sedation, revision surgery, surgical fixation for periprosthetic fractures), and revision rate (5.7% vs. 0.5%, p = 0.003) than patients undergoing primary THA. Patients who had failed fixation for acetabular fractures were younger and tended to recover well. Patients with previous intertrochanteric fracture had the longest operative time, more hip pain (83.8%, p = 0.022) and more complications. CONCLUSION: Salvage THA in posttraumatic hip arthritis after failed internal fixation required a longer operative time and led to more blood loss and postoperative complications. The dislocation, reoperation, and revision rates after salvage THA were higher than those after primary THA. Patients with salvage THA after failed internal fixation for intertrochanteric fractures were the most susceptible to more complications compared to those with femoral neck fracture or acetabular fracture. Level of Evidence level III.
