This study aims to assess the impact of COVID-19 admission delays on clinical outcomes, specifically complications and mortality, in elderly patients following hip fracture surgery.Materials and methods: This study included 563 patients (aged ≥70 years) who underwent hip fracture surgery between February 2018 to January 2021 and were followed up for at least one year. The cohort was divided into two groups: a pre-COVID-19 pandemic group (control group) and a COVID-19 pandemic group (study group). The patients who tested positive for COVID-19 were excluded. The demographic data, the time from injury to surgery, admission to surgery, postoperative complications, and 1-year mortality were collected and compared between the two groups.Results: The time from injury to surgery was significantly longer in the study group compared to the control group, primarily due to delays in the time from injury to hospital visit and from hospital visit to admission (4.6 days vs. 3.7 days, P=0.026). However, there was no significant difference between the groups from admission to operation. The incidence of postoperative medical complications and one-year mortality rate were significantly higher in the study group (P=0.025 and P=0.034).Conclusion: Our findings suggest that delays in the time from injury to hospital visit and hospital visit to admission during the COVID-19 pandemic led to significant delays in hip fracture surgery for elderly patients. These delays were associated with increased postoperative medical complications and a higher one-year mortality rate.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"37 3","pages":"223-229"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12417860/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144980975","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}

However, regarding the particular need for reduction before fixation, the optimal surgical strategy for this type of injury remains controversial. A comprehensive literature search was performed using PubMed, Embase, and Cochrane Library databases. Studies comparing outcomes between in-situ fixation and reduction with fixation for VIFNF published between 2014 and 2024 were included. Utilizing the Modified Coleman Methodology Score, study quality was assessed by two independent reviewers. Eleven studies published during the selected timeframe met the inclusion criteria. Studies on in-situ fixation reported significant femoral neck (FN) shortening regardless of screw configuration. Two of three comparative studies between in-situ and reduction demonstrated significantly less FN shortening in the in-situ group at the postoperative one year follow-up. Furthermore, all three comparative studies reported significantly higher postoperative 1-year Harris hip scores in the reduction group. For VIFNF, anatomical reduction prior to fixation may improve functional outcomes and reduce FN shortening compared to in-situ fixation. However, reduction techniques may offer better long-term stability and lower complication rates although they require additional surgical steps. Nevertheless, patient selection remains crucial, particularly in elderly or osteoporotic patients where in-situ fixation may still be a viable option. Further prospective randomized controlled trials are needed to confirm these findings.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"37 3","pages":"178-186"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12417868/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144981072","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}

Treatment of such fractures using modified Stoppa approach (MSA) either alone or in combination with lateral window of the ilio-inguinal approach has been reported. Whether this line of management is appropriate or not is a matter of further investigation. This study presents the clinical and radiological outcomes of acetabular both-column fractures using this approach.Materials and methods: Forty-one patients treated with MSA for anterior column with posterior hemi transverse (AC with PHT), associated both columns, T-type, and transverse fractures were postoperatively assessed at a minimum of one year. Their immediate postoperative reduction quality, as well as the clinical, radiological, and functional outcomes at the most recent follow-up visit were reviewed.Results: Most patients were young males injured in motor vehicle accidents who underwent surgery after a mean delay of 4.8 days. The mean surgical time was 122.44 minutes, and mean blood loss was 413.41 mL. AC with PHT fracture was the most common. In 78.0% of cases, anatomical reduction was achieved. At one year, excellent radiologic, clinical, and functional outcomes were observed in 78.0%, 51.2%, and 73.2% patients, respectively. There were eight cases with major complications.Conclusion: Using the MSA with satisfactory short-term results, it was possible to address acetabular fractures involving both the anterior and posterior elements in a select group of patients. A pelvi-acetabular surgeon should have expertise in using multiple surgical approaches including the MSA.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"37 3","pages":"230-237"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12417866/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144981015","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}

However, this unidimensional index cannot fully reflect anatomic shape features and variations of iliac wing and bony acetabular roof (IW-AR) coronal outlines that may influence DDH. This study aimed to analyze the shapes of IW-AR outlines by revealing their mean shape, possible shape variations, and the impact of these variations on the α angle variability.Materials and methods: By segmenting US images of 510 infant hips, IW-AR outlines in Graf's standard plane were obtained from a mixed screening population. A statistical shape model (SSM) was then developed to analyze the outline shapes.Results: In the IW-AR outlines, shape variations were described by linear combinations of six global and local shape modes. A global mode, dominantly causing an entire outline to bend about the vicinity of its apex, could affect the α angle in a large range (38°-70°). Although a local mode produced bending patterns that had a lesser impact on the α angle (up to 6°), it may relate to DDH diagnosis and clinical outcome.Conclusion: Shape variations in IW-AR outlines can be effectively modeled by using a compact SSM representative of the variations as linear combinations of a few global and local modes. The shape variations and the angle variability by the local modes should not be underestimated even though the effect of global modes on the α angle is dominant.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"37 3","pages":"187-196"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12417863/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144981157","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}

Propensity score matching was performed at a 1:4 ratio to adjust for baseline characteristics. The primary outcome was periprosthetic complications; the secondary outcome was medical complications.Results: Compared with the BHA-matched group, the DMC-THA group showed a higher rate of early periprosthetic fracture (2.6% vs. 1.4%, P=0.02) and late dislocation (1.1% vs. 0.5%, P=0.03). No significant differences were observed in periprosthetic joint infection or revision. Regarding medical complications, DMC-THA was associated with more transfusions (63.1% vs. 57.6%, P<0.001) but fewer urinary tract infections (3.4% vs. 5.1%, P=0.01). Multivariable analysis identified DMC-THA as an independent risk factor for early periprosthetic fracture (odds ratio [OR] 3.01, 95% confidence interval [CI] 1.39-6.80, P=0.004) and late dislocation (OR 2.53, 95% CI 1.18-5.42, P=0.02).Conclusion: DMC-THA was not superior to BHA in preventing dislocation and was associated with a higher risk of periprosthetic fracture and late dislocation in neurologically impaired patients. Surgeons should recognize the risks of using DMC-THA implants as a sole strategy to prevent instability in this high-risk population.","PeriodicalId":73239,"journal":{"name":"Hip & pelvis","volume":"37 3","pages":"213-222"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12417867/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144980899","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}

However, these surface types may also facilitate bacterial adherence and risk of infection. This aim of this study is to characterize the bacterial growth and viability on the different titanium surfaces used in THA implants.Materials and methods: Smooth and rough titanium samples were cleaned, sterilized, and prepared for bacterial testing. Staphylococcus aureus cultures were applied to the samples, incubated to allow for bacterial adherence, and stained to visualize and quantify bacterial coverage using fluorescence imaging and ImageJ software. Student's t-test was used to compare the percentage of bacterial coverage at each timepoint between smooth and rough samples. Finally, scanning electron microscopy (SEM) was used to observe and compare the surface structure and bacterial adherence at a microtopographic level.Results: Microtopographic differences between surfaces showed extensive irregularities in the rough samples as compared to the uniform grooved surface of the smooth samples. Confocal imaging showed greater bacterial coverage on the rough surfaces compared to smooth ones at all timepoint including 6 hours (7.85% vs. 3.89%, P=0.049), 12 hours (17.68% vs. 9.54%, P=0.0038), and 24 hours (20.77% vs. 13.26%, P=0.0024).

The current literature on ACH is sparse, with few studies addressing its pathophysiology, clinical presentation, diagnosis, and treatment. This review aims to consolidate existing knowledge on ACH to provide a comprehensive overview, drawing parallels with adhesive capsulitis of the shoulder (ACS). We explore the similarities and differences in pathophysiology between ACH and ACS, review the clinical manifestations of ACH, and discuss the diagnostic challenges faced by clinicians. Furthermore, we evaluate current conservative and surgical treatment strategies and their outcomes, highlighting the noted limitations in the available evidence.

The objective was to determine if chronological age alone defined frailty and if a dedicated hip fracture unit would improve patient outcomes.Materials and methods: The retrospective study was conducted over 16 months (January 2017 to April 2018), and included patients undergoing hemiarthroplasty, categorized into Group 1 (aged <90 years) and Group 2 (aged 90 years and above). Detailed data were collected on demographics, mobility, co-morbidity, operative aspects, delays, and mortality. Statistical analysis employed IBM SPSS ver. 25.0, utilizing Mann-Whitney U, Fisher exact, and chi-squared tests with a significance level of <0.05.Results: Of the 203 patients in our study cohort, 151 were in Group 1, and 52 in Group 2.
