However, there is a lack of consensus on which of these is more effective clinically. Whilst several biomechanical analyses of cadaveric hips show a higher construct stability of DHS fixation, there is a paucity of large clinical studies investigating patient outcomes.Materials and methods: Data from 2,705 patients at a single institution, including 322 internal fixations, were analysed retrospectively. Propensity scores were calculated to mitigate for the impact of covariates such as age, sex, Charlson comorbidity index and Nottingham Hip Fracture Score, producing an eligible group of 255 patients.Results: The CS group included 204 patients (mean age, 82.5±7.5 years; female, 90.7%), the DHS group included 51 patients (mean age, 82.4±8.0 years; female, 90.2%). There were no differences between groups after propensity matching. There were no significant differences in outcomes between CS and DHS groups for reoperation rate (CS 5.9% vs. DHS 5.9%, P>0.999), death <30 days (CS 5.9% vs. DHS 5.9%, P>0.999), length of stay (CS 11.5 days vs. DHS 14.0 days, P=0.294) and hours to surgery (CS 31:03 hours vs. DHS 29:23 hours, P=0.618). However, operation time was significantly shorter for CS (CS 39.0 minutes vs. DHS 44.0 minutes, P=0.013), an 11% reduction.Conclusion: There is no difference in clinical outcomes between CS and DHS fixation of intracapsular hip fractures. However, in this cohort the operating time was approximately 5 minutes shorter in CS fixation.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"38 1","pages":"101-109"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12976690/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147345921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, there are no reviews that directly compare the design features of these implants. We performed a manual review of the designs of commercially available diaphyseal engaging femoral stems. We compiled and compared the design features of these implants. Clinical outcomes of modular and monoblock stems were also compared. We identified five modular and four monoblock stems in the manual review of commercial companies manufacturing these stems. Distal stem taper varied from 2° to 3.5°, and the number of splines varied from 8 to 16. The stems varied in their stem lengths, offsets, and surface finish. Although there are no clinically significant differences in the restoration of leg length between monoblock compared to modular stems. The modular stems appear to perform slightly better with respect to subsidence and restoration of leg length. A source of concern for modular stems are mechanical implant failures that occur almost exclusively at modular junctions. Current evidence does not support any difference in dislocation rate, intraoperative or postoperative fracture, aseptic loosening, re-revision rates, or clinical outcomes between monoblock and modular stems. With the knowledge of the distinct features of implants, surgeons must make choices associated with specific design characteristics that could be pivotal to the success of the operation. Our understanding of design differences will help us minimize chances of failure and choose patient-specific implants that will lead to a high rate of success.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"38 1","pages":"14-26"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12976693/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147345589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed PASS score and MCID between iHOT12J and JHEQ preoperatively and at 2 years postoperatively in patients underwent hip arthroscopy.Materials and methods: PASS score and MCID were calculated using pre- and two years post hip arthroscopy iHOT12J and JHEQ data from 99 patients. Anchor-based method was used to calculate PASS, which involved dividing patients into two groups based on their JHEQ satisfaction visual analog scale as well as performing receiver operating characteristic (ROC) curve analyses. ROC curve and PASS score were computed using obtained values and Youden index, respectively. Value with the greatest sensitivity and specificity was target value. MCID was calculated with 0.5 standard deviation (SD) method by dividing the mean of iHOT12J and JHEQ values, obtained from pre- and at two years post-surgery, by 0.5.Results: PASS scores were 74.2 for iHOT12J and 62.0 for JHEQ. SD was 24.8% for iHOT12J and 19.4 for JHEQ. MCID was 12.4 for iHOT12J and 9.7 for JHEQ. Achievement rates of PASS and MCID were 73/99 (73.7%) for iHOT12J and 89/99 (89.9%) for JHEQ.Conclusion: PASS score and MCID could serve as measurable benchmarks to define significance in patient-reported outcome measure values for clinical outcomes or variables of postoperative hip arthroscopy.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"38 1","pages":"62-71"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12976702/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147345653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study aimed to evaluate and compare (1) surgery-associated parameters and (2) mortality rates following multiple screw fixation (MSF) or cementless bipolar hemiarthroplasty (BHA) in patients with displaced FNF using twenty years of data from a single tertiary referral center.Materials and methods: Between January 2000 and January 2018, we analyzed 1,153 cases of displaced FNFs treated at our institution with either MSF or cementless BHA. We evaluated (1) surgery-associated parameters, (2) hospitalization duration, and (3) postoperative complications and mortality rates at one and five years following the surgical procedure.Results: MSF showed a reduced waiting period preceding surgery, a shortened duration of the surgical procedure, but an extended period of hospitalization. There was an increase of estimated blood loss and postoperative transfusion with cementless BHA compared to that with MSF. Both the procedures did not differ in postoperative complications. The one-year and five-year mortality rates were also similar in both groups.Conclusion: Since cementless BHA and MSF surgeries did not distinctly differ in mortality rates at one year and at five years, it is crucial that surgeons make personalized surgical decisions based on the individual characteristics of the patient. Surgeons should carefully weigh the advantages of MSF, which include shortened surgery time and low blood loss against the benefits (e.g., reduced hospitalization period) of cementless BHA.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"38 1","pages":"93-100"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12976698/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147345888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the number of reported complications is low, emergency room visits in the early postoperative period do occur. This study aims to evaluate the impact of demographic, insurance, and clinical factors on the likelihood of postoperative emergency department (ED) visits following hip arthroscopy. Through the identification of key risk factors, including insurance status, comorbidities, and procedural specifics, the objective of this study is to inform clinical practices and enhance patient outcomes through targeted risk management.Materials and methods: A retrospective review of a multi-center institutional database identified patients who underwent hip arthroscopy between 2014 and 2022. Medical records were analyzed for ED visits within the first 30 postoperative days. Diagnoses leading to ED visits were classified by pathology such as pain, musculoskeletal, or infection. Factors associated with increased odds of ED visits were assessed utilizing a multivariate regression analysis.Results: Of the 879 hip arthroscopies, 3.1% of patients had ED visits within 30 postoperative days. Medicaid patients were 2.88 times more likely to visit the ED (P=0.025). The presence of hypertension (P=0.013) or autoimmune conditions (P=0.041) further increased the odds. The use of a capsular closure technique during surgery reduced ED visits by 69.1% (P=0.026).Conclusion: Following hip arthroscopy, patients with Medicaid insurance, hypertension, and auto-immune disorders are more likely to require ED visits within 30 days. In contrast, the use of a capsular closure technique significantly reduces the likelihood of such visits.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"38 1","pages":"54-61"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12976704/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147345902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spondylolysis of L5 is common in 4% to 8% of the population. L5 spondylolysis could potentially affect acetabular orientation since it is associated with alterations in the sacral and pelvic parameters. In our study, we aimed to assess the influence of L5 spondylolysis on acetabular orientation.Materials and methods: In 23 patients with L5 spondylolysis and 46 control patients, we assessed the correlation between the pelvic parameters-pelvic incidence (PI), sacral anatomic orientation (SAO), and acetabular sagittal angle (ASA) using computed tomography analysis. The ASA is measured by the angle subtended by the line joining the anterior and posterior horns of the acetabulum in the midsagittal slice of the joint and the line through the anterior pelvic plane (APP).Results: Twenty-three patients with L5 spondylolysis were matched by age and sex (16 males; mean age, 46.1 years) to 46 control patients (32 males; mean age, 46.3 years). The PI and the ASA were significantly higher in those with spondylolysis, which indicates greater acetabular coverage relative to the APP. Linear regression analysis suggested a greater influence on ASA by the SAO than PI.Conclusion: Clinicians should be aware of the impact of elevated PI on the changes to the sagittal acetabular inclination and its association with spondylolysis. It should also be noted that spondylolysis alone does not appear to influence acetabular inclination in the sagittal plane.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"38 1","pages":"27-34"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12976703/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147345892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
