Purpose: This study was undertaken in order to identify the characteristics of patients diagnosed with occult an hip fracture after hip trauma. Methods: We retrospectively reviewed the medical records and radiology reports of all patients who underwent hip skeletal computed tomography (CT) for suspected hip fractures but had normal initial X-rays after hip trauma between August 2006 and January 2012. The variables evaluated included age, gender, body mass index (BMI), accident mechanism, previous fracture, independence, late presentation, ability to bear weight, pain on passive rotation, tenderness of the groin area, diagnosis and treatment. Patients were divided into two groups, with hip fracture (occult hip fracture group) and without hip fracture (no fracture group) to evaluate the characteristics associated with an occult hip fracture. Results: The patients, a total of 139, had a mean age of 58.3 years and included 72 male patients(51.8%). The occult hip fracture group included 43 patients(30.9%). Of those 43, 21 patients(48.8%) had intertrochanteric or trochanteric fractures, 8 patients(18.6%) had femur neck fractures and 14 patients(32.6%) had acetabular fractures. Of the 43, 15 patients(34.9%) needed operative treatment. Age was higher in the occult hip fracture group than it was in the no fracture group(64.4±19.1 years vs. 55.5±23.6 years, p=0.021). A previous fracture was associated with the presence of a new fracture (p=0.014; OR=3.971, 95% CI=1.314-11.997). Conclusion: Further evaluation of patients who are older or have history of fractures is prudent, even though the initial X-rays are normal.

Boo-Seop Kim,Jae-Young Lim,하용찬 대한고관절학회 2020 Hip and Pelvis Vol.32 No.3

The aging of the Korean population is expected to result in an increase in the prevalence of hip fractures. The aim of this review is to evaluate potential hip-fracture trends in Korea during the last few decades. Data from a hip fracture-related epidemiology study informed by: (1) a cohort study; (2) hospital-based cohort study; and (3) claims database, were reviewed and summarized. The incidence of hip fractures rose from 159.1/100,000 in 2008 to 181.5/100,000 in 2012, and the total number of hip fractures is estimated to increase by 1.4 times over the next 10 years (35,729 in 2016 to 51,259 in 2025). The use of intramedullary nails has greatly surpassed the use of plates for the treatment of intertrochanteric fractures. The 1-year cumulative mortality rates in patients aged ≥50 years after hip fractures based on National Health Insurance Service data were 17.2% (3,575/20,849) in 2008 and 16.0% (4,547/28,426) in 2012; the decrease was mainly observed among women. In addition, the mean 1-year mortality rates were 21% for men and 15% for women, indicating that mortality was 1.4 times higher in men than in women. The number of hip fractures is rapidly increasing, and the incidence of hip fractures demonstrated a slightly increasing trend until 2012. Trends in the use of varying surgical options for treatments for femoral neck and intertrochanteric fractures follow global trends. Although the high mortality rate after hip fractures in Korea remains concerning, a decrease in these rates over the study period was observed.

( Yong Geun Park ),( Sun Mee Jang ),( Yong Chan Ha ) 대한고관절학회 2014 Hip and Pelvis Vol.26 No.4

Purpose: Although the incidence of a second hip fracture is relatively well described, mortality and morbidity after a second hip fracture are seldom evaluated. The purpose of this study was to determine the incidence, morbidity, and mid-term mortality of a second hip fracture and evaluate the cause of death after a second hip fracture. Materials and Methods: Information on patients older than 50 years, who sustained a subsequent hip fracture, were obtained from the records of eight Jeju Island hospitals between 2002 and 2011 to calculate the incidence, morbidity, and mortality of hip fractures in this age group. All patients were followed a minimum of 2 years. A systemic search for death certificates at the National Statistical Office was conducted for patients who were lost to follow-up. Results: Of 2,055 hip fractures (419 men and 1,636 women), 98 were second hip fractures (13 men and 85 women) during the study period. The mean ages of the patients at the time of the first and second fractures were 78.8 and 80.8 years, respectively. The incidence of a subsequent hip fracture among the first hip fracture was 4.8%. Mean mortality rates at 6 months, 1 year, 2 years, and 5 years were 10.5%, 15.2%, 23.5%, and 42.0% respectively. Cumulative mortality after the second hip fracture at the 5 years follow-up was 41.8%. Conclusion: Our results demonstrate that a secondary fracture prevention program is necessary to prevent second hip fractures in elderly patients.

홍상모,한경도 대한골다공증학회 2019 Osteoporosis and Sarcopenia Vol.5 No.2

Objectives: Osteoporotic hip fractures are associated with high mortality in the older population. Few population studies have reported the long-term trends of incidence and mortality rate of hip fracture among the older in Korea. This study assessed the incidence and mortality rate within 1 year after hip fracture from 2006 to 2015 in South Korea. Methods: The National Health Information Database was used to identify adults aged 60 years and older with a diagnosis of hip fracture and died within 1 year from hip fracture. Regression analyses were performed to estimate the change of the incidence of hip fracture and the related mortality rate. Results: The events causing hip fracture increased 1.85 times (1.91 times in women and 1.71 times in men), and the incidence of hip fracture increased 1.23 times (1.30 times in women and 1.11 times in men) from 2006 to 2015. The mortality rate after hip fracture decreased by 10% in women; however, it increased by 13% in men. These trends were more prominent in the older population. Conclusions: Although the mortality rate after hip fracture in women decreased, other parameters associated with hip fracture have worsened during the last decade. Nationwide programs were urgently needed to reduce the future socioeconomic burdens of hip fractures.

Recent Updates of the Diagnosis and Prevention of Venous Thromboembolism in Patients with a Hip Fracture

( Won Chul Shin ),( Sang Min Lee ),( Kuen Tak Suh ) 대한고관절학회 2017 Hip and Pelvis Vol.29 No.3

Venous thromboembolism (VTE) is a potentially fatal complication that is relatively common after hip surgery. Since patients with a hip fracture have a higher risk of preoperative VTE due to an inability to ambulate after injury and aggravation of underlying age-related conditions, it may be difficult to effectively prevent VTE using only conventional approaches. Very few studies have been published reporting on the prevalence and prevention of VTE in patients with a hip fracture compared to those with hip arthroplasty. For this reason, we aimed to share recent updates on the diagnosis and prevention of VTE in patients with a hip fracture. Preoperative screening tests to diagnose VTE need to be performed more actively following hip fracture and indirect multidetector computed tomography venography is considered the most effective test for this purpose. As the risk of VTE appears to increase with time following a hip fracture, preventive measures should be taken as soon as possible in patients with a hip fracture. A wide variety of mechanical and pharmacological options are available for prophylaxis. When considering patient compliance and preventive impact, intermittent pneumatic compression devices and foot pumps are recommended as mechanical modalities. Of the available preventive medications for patients with a hip fracture, low molecular weight heparin seems to be the most appropriate option because of its short half-life and fast onset of action. Surgery should be performed as soon as possible in patients with hip fractures, and we recommend mechanical and pharmacological methods as active interventions immediately after injury to prevent VTE.

Trend in the Age-Adjusted Incidence of Hip Fractures in South Korea: Systematic Review

이영균,김진우,이명호,문경호,구경회 대한정형외과학회 2017 Clinics in Orthopedic Surgery Vol.9 No.4

Background: The incidence of hip fractures has been reported to vary geographically, and its trend has also varied widely. However, the trend in the age-adjusted incidence of hip fractures has not been well studied in Korea. After we identified eligible studies presenting multiple age-adjusted incidences of hip fractures in the Korean population in PubMed, we evaluated changes in the absolute number of occurrence and calculated the annual percentage change (APC) of age-adjusted incidences of hip fractures. Methods: We have searched PubMed for the original and English-language literature on the incidence of hip fractures in the Korean population published since 2000. The studies presenting multiple age-adjusted incidences of hip fractures were selected. We evaluated the change in the absolute number of hip fractures and calculated the APC of age-adjusted incidences of hip fractures for each study. Results: Three eligible articles were identified. The absolute number of hip fractures for both genders increased over time in all three studies although the operational definition of hip fracture differed from one another. The APC of the age-adjusted incidence of hip fractures was positive for women and negative for men. However, the change was not statistically significant in both genders during each study period (2001–2004, 2005–2008, and 2006–2010, respectively). Conclusions: The age-adjusted incidence of hip fractures was stable among men and women, while the absolute number of hip fractures increased for both genders in Korea. Further studies with longer study periods on age-adjusted incidences are required to better determine the trend in the incidence of hip fractures in Korea.

Outcomes of Surgical Treatment of Periprosthetic Femoral Fractures in Cementless Hip Arthroplasty

( Min Wook Kim ),( Young Yool Chung ),( Jung Ho Lee ),( Ji Hoon Park ) 대한고관절학회 2015 Hip and Pelvis Vol.27 No.3

Purpose: We aimed to evaluate the results of surgical treatment of periprosthetic femoral fractures in cementless total hip arthroplasty (THA). Materials and Methods: From June 2002 to May 2012, 40 patients who could be followed-up for more than 1 year after surgery were enrolled in this study. The mean duration of follow-up was 28.5 months (range, 15-97 months) and the average age at the time of surgery was 71.5 years (range, 38-89 years). The fracture types were determined by using the Vancouver classification. Among intraoperative fractures, there were type A in 3 hips, type B2 in 2 hips and type B3 in one. Among postoperative fractures, type AG was present in 5 hips, type AL in 2 hips, type B1 in 15 hips, type B2 in 6 hips, type B3 in 3 hips, and type C in 3 hips. Evaluation of the results was based on bony union, stability of the prosthesis, postoperative complications, and Harris hip score at the final follow-up. Results: Bony union was achieved in all but one case and the average time for bony union was 21 weeks. The mean Harris hip score was 86 at the final follow-up. Clinical results were above good in 34 of 40 hips (85.0%). Stem loosening occurred in one patient with a type B1 fracture treated with open reduction and plate fixation. Nonunion was observed in 1 patient with an AG type fracture. Conclusion: Open reduction and fixation using a plate with a screw and cerclage wiring provided good results for periprosthetic fractures in patients who had a stable femoral stem without bone defects. Revision surgery with a cementless long stem should be considered in patients with an unstable stem or suspected stability in B1 type of THA using a proximal fixation type.

Effectiveness of Hip Arthroscopy Performed Simultaneously before Open Reduction and Internal Fixation for Acetabular Fracture and Fracture-dislocation of the Hip

( Hyeon Jun Kim ),( Sung Soo Kim ),( Young Hun Jung ),( Kyung Ho Lee ) 대한고관절학회 2018 Hip and Pelvis Vol.30 No.2

Purpose: This study is performed to evaluate the usefulness of arthroscopic surgery prior to open reduction and fixation surgery to treat acetabular fractures and hip fractures-dislocation. Materials and Methods: From January 2010 to March 2014, a total of 54 patients with acetabular fractures or hip fractures with dislocation were treated arthroscopically via fracture surface before open reduction and fixation (group 1, n=11), and without hip arthroscopy prior to open reduction and fixation (group 2; n=43). Clinical results were evaluated using Harris hip score (HHS) and visual analogue scale (VAS) pain scores. Results: The mean age of patients is 43.2 years and there are 10 males and 1 females in group 1. The mean follow-up period is 15 months. The acetabular status of each case was assessed arthroscopically. Bone fragment was performed in 6 cases, and ligamentum teres shrinkage in 1 case. At the final follow up, the mean HHS and VAS pain scores were 78.6 and 2.18, respectively. During follow up, one case of osteoarthritis and one case of heterotopic ossification were identified. At the final follow up, the mean HHS and VAS pain scores were 77.5 and 2.23, respectively. In group 2, oteoarthritis and ectopic ossification were observed in 4 and 1 cases, respectively. Conclusion: No differences were observed in the clinical outcomes of patients with acetabular fracture or hip fracture-dislocation when treated with or without arthroscopic surgery before open reduction and fixation. However, arthroscopy is thought to be useful for evaluating the joint cartilage surface and fracture fragments more accurately.

( Jaiben George ),( Vijay Sharma ),( Kamran Farooque ),( Samarth Mittal ),( Vivek Trikha ),( Rajesh Malhotra ) 대한고관절학회 2021 Hip and Pelvis Vol.33 No.2

Purpose: Hip fractures are a major cause of morbidity and mortality in the elderly; however, the current literature on the injury patterns of hip fractures in India is lacking. Understanding the injury profile of these patients is important to develop targeted interventions to prevent hip fractures. Materials and Methods: This was a prospective study of all hip fracture patients aged 50 years or older admitted from February 2019 to December 2019. Details about the injury were recorded by an in-person interview. Multivariate logistic regression analysis was used to identify the factors associated with any particular injury mechanism. Results: Two hundred and eighty-three hip fractures were included. The mechanism of injury for the majority of patients was a fall from a standing height (n=217, 76.7%) while 60 patients (21.2%) were injured as the result of a road traffic accident (RTA). Slipping on a wet floor (n=49, 22.6%) and change in posture (n=35, 16.1%) were the most commonly reported reasons for falling. Pedestrian injuries were the most common form of RTA (n=29, 48.3%). Increasing age (P<0.001) and female sex (P=0.001) were associated with fall as the mode of injury while sustaining another fracture in addition to hip fracture (P=0.032) was associated with RTA as the mode of injury. Conclusion: A fall from standing height is the predominant mode of injury among elderly hip fractures especially among women. Environmental hazards and postural changes are responsible for the majority of falls while pedestrian accidents contribute to a majority of the RTAs.
