The optimal entry point is considered a critical step in avoiding malreduction. This study investigated the effects of various entry points on fracture displacement and force reduction.\u0000Methods: Twenty-four cadaveric femurs were randomly categorized into three groups: the greater trochanter (GT) tip, medial to the GT tip, and lateral to the GT tip. Each intact femur was provisionally stabilized using a ring external fixator. The entry point was identified and reamed to accommodate the nail insertion. After osteotomy was performed to simulate an A1-type fracture, the PFN was inserted. Digital calipers were used to measure horizontal fracture displacements. The force required to reduce displaced fractures to the anatomical position was measured using a digital force gauge. Fluoroscopic images were recorded to assess changes in the neck-shaft angle.\u0000Results: The lateral entry group showed significantly displaced fractures in the coronal plane, whereas the medial and tip entry groups were insignificant. Displacement in the sagittal plane was not significantly different between the groups. The lateral entry group showed significantly irreducible displaced fractures compared with the other groups. After nail insertion, the changes in the neck-shaft angle were 0.77° varus, 3.66° valgus, and 3.16° varus in the tip, medial, and lateral entry groups, respectively. The degree of neck-shaft angle change demonstrated significant differences between the groups.\u0000Conclusions: The lateral entry point of PFNA tends to displace reduced fractures, resulting in malalignment and irreducibility. Lateral entry points should be avoided to prevent surgery-related complications.","PeriodicalId":333749,"journal":{"name":"Journal of Southeast Asian Orthopaedics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126300831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However there is no consensus on bipolar hemiarthroplasty (BHA), which has a lower dislocation rate, less blood loss and shorter operative time, while total hip arthroplasty (THA) provides better functional and long term outcomes. This study aimed to evaluate patient function and complications following both BHA and THA in an elderly population who presented with DFNF.\u0000Methods: A prospective, randomized controlled trial comparing BHA and THA for DFNF treatment was performed. Patients over 60 years of age with DFNF (Garden’s classification types 3 and 4) participated in this study, while patients with preexisting hip conditions and impaired cognitive function were excluded from the study. All operations were performed by a single surgeon using the same techniques the posterior approach. Demographic data, intraoperative blood loss, operative time, and morbidity and mortality statistics were collected. Patients were followed up at 1, 3, 6 and 12 months and their functional scores were calculated according to the Harris hip score. Statistical analyses were performed to the intention-to-treat principle.\u0000Results: The cohort comprised 75 patients, with 38 patients in the BHA group (mean age 76.7 years) and 37 patients in the THA group (mean age75.7 years). The mean operative times for the BHA and THA groups were 40.76 and 51.08 minutes respectively. The average intraoperative blood loss was 200 cc and 279.7 cc, respectively. The mean hospital stay was 5.07 days for the BHA group and 4.92 days for the THA group. The mean Harris hip scores at 1, 3, 6 and 12 months in the BHA group were 71.5, 78, 85 and 86, respectively, while in those in the THA group were 71, 79, 85.5 and 88 respectively. Statistically, there were no significant difference between the two groups. Morbidities including fractures and dislocations, and mortality rates, also showed no statistically significant difference.\u0000Conclusions: Harris hip score, dislocation, length of hospital stay and mortality rate at one year is not statistically different between group.

Surgical treatment is generally required to achieve a good quality of life. It was reported that a delayed time from injury to treatment leads to poor outcomes. We aimed to determine the time interval from injury to hospital admission in patients with geriatric hip fractures and explore the reasons for delay.\u0000Methods: Information on geriatric hip fracture patients who received treatment at our hospital from November 2016 to October 2020 was extracted from medical records. The average delay time was analyzed and reported. The reasons for delay were collected from patients who were not referred from other hospitals and had a time interval from injury to admission of more than 24 h.\u0000Results: The median time interval was 0.38 days, and 127 (32%) visited the hospital more than 24 h later. In patients not referred from other hospitals, the most common cause of delay was that patients overlooked the possibility of bone fractures (58%). Other reasons included unavailable transportation (20%), missed diagnosis from other hospitals (11%), inability to afford the transportation cost (7%), and inability to talk and/or caregivers did not notice the injury (4%).\u0000Conclusions: Almost one-third of geriatric hip fracture patients had a time from injury to admission of more than 24 h. Knowing the reason for delay and determining a solution to minimize this time interval may improve treatment quality. This information demonstrates that public and healthcare providers should pay attention to elderly patients with a history of fall injury.","PeriodicalId":333749,"journal":{"name":"Journal of Southeast Asian Orthopaedics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134050821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Resident physicians were offered video podcasts to compensate for the loss of lecture hours but without proven efficacy. This study aimed to investigate the effectiveness of video podcasts related to osteoporotic and metabolic bone diseases during residency training.\u0000Methods: Orthopedic residents were voluntarily allocated to the video podcast or traditional group. Twenty-two video podcasts covering major topics in osteoporosis and metabolic bone diseases were developed by experts and offered to the podcast group. Each podcast was approximately 20-30 minutes long. Pre- and post-exposure examinations, comprising 60 multiple-choice questions, were conducted and compared. Confidence, perceived ability, and preferences were assessed using questionnaires.\u0000Results: A total of 37 residents were recruited, 18 in the video group and 19 in the traditional group. With numerically lower pre-test scores (47.59%±9.77% in the video group, 53.95%±9.77% in the traditional group, p = 0.056), students in the video group significantly outperformed the traditional group in the post-test (89.81%±3.83% and 76.93%±10.92%, p < 0.001). Junior residents watching videos scored higher than senior residents. Videos led to a greater gain in confidence and perceived ability. However, students still preferred live lectures to videos.\u0000Conclusions: This study showed greater performance scores and confidence when using video podcasts, with junior residents improving more with podcasts. We suggest providing supplemental video podcasts in non-surgical-based subspecialties during the early training years as a supplement during the pandemic and a new normal residency training method.","PeriodicalId":333749,"journal":{"name":"Journal of Southeast Asian Orthopaedics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117251389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
