ABSTRACT

Background@#Increasing longevity has caused the very old population to become the fastest-growing segment. The number of centenarians (over 100 years old) is increasing rapidly. Fractures in the elderly lead to excessive medical costs and decreased quality of life with socioeconomic burdens. However, little research has thoroughly examined the functional outcomes and mortality of hip fractures in centenarians. @*Methods@#This is a retrospective observational study. Sixty-eight centenarian hip fracture patients were admitted to the 10 institutions from February 2004 to December 2019. Fifty-six patients with 1-year follow-up were finally included. The following data were obtained: sex, age, body mass index, Charlson comorbidity index value on the operation day, Koval’s classification for ambulatory ability, type of fracture, the time interval from trauma to surgery, American Society of Anesthesiologists grade, surgery-related complications, and duration of hospital stay. Postoperative Koval’s classification (at 1 year after surgery) and information about death were also collected. Multivariate analysis was performed to analyze the risk factors affecting mortality 1 year after surgery. @*Results@#Mortality rates were 26.8% at 6 months and 39.3% at 1 year. The 90-day mortality was 19.6%, and one of them (2.1%) died in the hospital. The 1-year mortality rates for the community ambulatory and non-community ambulatory groups were 29% and 52%, respectively. Only 9 (16.1%) were able to walk outdoors 1 year after surgery. The remaining 47 patients (83.9%) had to stay indoors after surgery. Multivariate analysis demonstrated that the pre-injury ambulatory level (adjusted hazard ratio, 2.884; p = 0.034) was associated with the risk of mortality. @*Conclusions@#We report a 1-year mortality rate of 39.3% in centenarian patients with hip fractures. The risk factor for mortality was the pre-injury ambulatory status. This could be an important consideration in the planning of treatment for centenarian hip fracture patients.

ABSTRACT

Pediatric ankle fractures are defined as damage to the metaphysis, epiphyseal plate, and epiphysis of the distal tibia and fibula. Although the injury mechanism could be similar, the fracture patterns and treatment of pediatric ankle fractures are different from those of adults. In children, growth plate injuries are more common with a force that would cause sprains in adults because the ligaments are stronger than the growth plate cartilage in children. In the adolescent period, unique fractures, called “transitional fractures”, occur while the physis is closed. For a diagnosis, plain images of the anteroposterior, lateral, and mortise views are essential. Stress radiographs, ultrasound, and magnetic resonance imaging can be used for suspected ligament injuries. The treatment goal is to restore the articular congruity, normal bony alignment, and preserve the epiphyseal plate to ensure normal growth. Pediatric ankle fractures frequently lead to premature physeal arrest, angular deformities, malunion, and posttraumatic arthritis even after anatomic reduction. Treating surgeons should follow-up children for a sufficient time and explain to the caregiver the possible complications before treatment.

ABSTRACT

Background@#The advancement of computer information technology would maximize its potential in operating rooms with touchless input devices. A picture archiving and communication system (PACS) was compared with a touchless input device (LMC-GW), relaying to another person to control a mouse through verbal guidance, and directly controlling a mouse. @*Methods@#Participants (n = 34; mean age, 29.6 years) were prospectively enrolled and given nine scenarios to compare the three methods. Each scenario consisted of eight tasks, which required 6 essential functions of PACS. Time elapsed and measurement values were recorded for objective evaluation, while subjective evaluation was conducted with a questionnaire. @*Results@#In all 8 tasks, manipulation using the mouse took significantly less time than the other methods (all p < 0.05). Study selection, panning, zooming, scrolling, distance measuring, and leg length measurement took significantly less time when LMC-GW was used compared to relaying to another person (all p < 0.01), whereas there were no significant differences in time required for measuring the angles and windowing. Although the touchless input device provided higher accessibility and lower contamination risk, it was more difficult to handle than the other input methods (all p < 0.01). @*Conclusions@#The touchless input device provided superior or equal performance to the method of verbal instruction in the environment of operating room. Surgeons agreed that the device would be helpful for manipulating PACS in operating rooms with less contamination risk and disturbance of workflow. The touchless input device can be an alternative option for direct manipulation of a mouse in operation rooms in the future.

ABSTRACT

Osteoporosis and osteoporosis related fractures contribute a large part of the medical cost in developed countries. Considering the preventive effect of osteoporotic medications, high rate of mortality and complications, poor quality of life after osteoporosis related fractures, the growing trend of older populations in the future, osteoporosis and osteoporosis related fractures are important targets of preventive treatment and also targets of socioeconomic cost reduction. Treating osteoporosis and preventing osteoporosis related fractures have become an essential element in Korean medical system. Despite the various differences in the health care system, hospitals in many other countries are operating fracture liaison service and they have confirmed its cost-effectiveness. In Korea's health care system, further research on cost-effectiveness as well as its clinical effects is needed.

ABSTRACT

Background@#The purpose of this study is to search for reports on the clinical effectiveness of FLS being implemented worldwide through the systematic review, analyze the roles of coordinators in each study, and provide basic data for the development of future coordinator education programs. @*Methods@#A systematic search of the literature using the Medline, PubMed, and EMBASE databases and the Cochrane Library was conducted for using the following keywords: ‘osteoporosis’ AND ‘fractures’ AND ’secondary prevention’. Finally, 65 studies are included in this study. @*Results@#At the coordinator-based fracture liaison service (FLS) center, the coordinator (often a nurse) acts as a central player in the establishing of patient connections, orthopedic surgeons, radiologists, and attending physicians. Coordinators help bridge the nursing gap by supporting identification, investigation, initiation of treatment, and patient follow-up. Medics has opened the way to effectively manage patients at high risk of developing another fracture. In addition, nurses are in a unique and important role as nurses responsible for enhancing their daily lives by building relationships with patients and families. @*Conclusions@#The coordinator in the FLS program plays an important role in the multidisciplinary management of vulnerable fractures, as well as in the diagnosis and treatment of osteoporosis and in maintaining continuity of treatment. In the future, the broader role of coordinators should be systematically organized and developed into accredited educational programs.

ABSTRACT

Background@#In this study, we aimed to analyze kinematic and kinetic changes in gait and to assess radiographic and clinical improvement after calcaneal lengthening osteotomy (CLO) in children with idiopathic symptomatic flexible flatfoot deformities. @*Methods@#The study group consisted of 22 children (28 feet) with idiopathic symptomatic flexible flatfoot, which was treated by CLO as an index operation. We excluded patients with flatfoot that developed secondary to neuromuscular diseases. There were 18 boys (22 feet) and 4 girls (6 feet). The average age of the patients was 10.8 ± 1.51 years. Surgical results were assessed by radiologic imaging, clinical evaluation, and gait analysis, which were performed before surgery and 1 year after surgery. Medical records were reviewed to check postoperative complications. @*Results@#Talonavicular coverage was recovered to 16.7° from 32.7° (p < 0.01). Lateral talo-first metatarsal angle and calcaneal pitch angle increased by 20.1° and 9.9°, respectively (p < 0.01). Weight-bearing radiographs demonstrated a decrease in the anteroposterior angle and lateral talocalcaneal angle by 6.9° and 10°, respectively (p < 0.01). Hindfoot valgus was corrected to near neutral position after CLO. Kinematic results showed that the ankle valgus angle in the coronal plane was reduced from 35.48° preoperatively to 16.64° postoperatively during gait (p < 0.05). The preoperative out-toeing gait (preoperative foot progression angle, 20.31°) was also normalized to 14.21° postoperatively. The kinetics results showed that the push-off moment (maximum ankle plantar flexion) on the sagittal plane increased from 0.66 Nm/kg preoperatively to 0.83 Nm/kg postoperatively (p < 0.01). The mean Yoo score was 9.2 ± 1.05 postoperatively: satisfactory in 24 cases (86%) and unsatisfactory in 4 cases. Of the 4 unsatisfactory cases, 2 cases were overcorrection and 2 cases were undercorrection, and 3 of them were well managed by wedge foot insoles. @*Conclusions@#The 3-dimensional deformities of the flexible flatfoot were effectively corrected by CLO, based on the morphological assessment using radiologic imaging. The correction was well maintained during gait at 1 year after the operation.

ABSTRACT

Background@#Controversy exists about the optimal treatment of midshaft clavicle fractures in the presence of significant displacement, comminution, or shortening of the fracture in adolescents. The purpose of this study was to compare the clinical and radiological outcomes of 4 different treatments for midshaft clavicle fractures in adolescents: conservative treatment with a figure-of-8 (FO8) brace, open reduction and internal fixation with a plate (OPL), minimally invasive plate osteosynthesis (MIPO), and intramedullary nail fixation with a threaded Steinmann pin (TSP). @*Methods@#A total of 94 teenagers with midshaft clavicle fractures were divided into the FO8, OPL, MIPO, and TSP groups (n = 24, 33, 16, and 21, respectively). We analyzed clinical and radiological outcomes and complications in each group and compared the results among the groups. @*Results@#All groups showed satisfactory clinical and radiological outcomes, but each group showed different results for the assessment items. The Constant-Murley scores were higher in the operated groups than in the FO8 group. Recovery of joint motion was faster in the operated groups. The TSP group had the highest cosmetic satisfaction with respect to the satisfaction score and measured scar length. Fracture union was achieved in all patients. At the final follow-up, the bone length was closer to normal in the OPL and TSP groups than in the FO8 and MIPO groups, and angulation was less in the OPL and TSP groups than in the MIPO and FO8 groups. The TSP and MIPO groups obtained faster bone healing than the OPL and FO8 groups. In the operated groups, 9 patients had metal-induced irritating symptoms; 1, supraclavicular nerve injury symptoms; and 4, refractures after plate removal. @*Conclusions@#The nonoperatively treated group had no iatrogenic complications. The operated groups complained of various disadvantages induced by surgery; however, these groups achieved faster functional recovery and slightly better radiological and functional results than the nonoperative group.

ABSTRACT

Background@#This nationwide study aimed to investigate the blood transfusion status of elderly hip fracture patients and to examine the effect of packed red blood cell transfusion on all-cause mortality. @*Methods@#From the Korean National Health Insurance Service-Senior cohort consisting of 588,147 participants aged over 60 years in 2002, a total of 14,744 new-onset hip fracture patients aged 65–99 years were followed up for 11 years. The adjusted hazard ratios (aHRs), risk ratios, and their 95% confidence intervals were estimated by the Cox proportional hazard model and Poisson regression model. @*Results@#There were 10,973 patients (74.42%) in the transfusion group and 3,771 (25.58%) patients in the non-transfusion group. The mean volume of blood transfusion was 1,164.51 mL (± 865.25; median, 800 mL; interquartile range, 640–1,440). In the multivariable-adjusted Cox proportional hazard model, the transfusion group had 1.34-fold more risk of all-cause mortality than the non-transfusion group (aHR, 1.34; 95% confidence interval [CI], 1.26–1.42). In the multivariate-adjusted Poisson regression model, hip fracture patients in the transfusion group were 1.43 (adjusted risk ratio [aRR], 1.43; 95% CI, 1.09–1.87; p = 0.009) folds more likely to die within 30 days than those in the non-transfusion group. The mortality risk was highest at 90 days (aRR, 1.64; 95% CI, 1.40–1.93; p < 0.001) and slightly decreased at 180 days (aRR, 1.58;95% CI, 1.40–1.79; p < 0.001) and 1 year (aRR, 1.43; 95% CI, 1.31–1.58; p < 0.001). @*Conclusion@#In this nationwide representative cohort study, blood transfusion was performed in 75% of hip fracture patients. Even after adjusting for comorbidity and anticoagulant use, the postoperative results (hospitalization, mortality) of the transfusion group did not show significantly worse results than the non-transfusion group. Therefore, adequate patient blood management can only improve the patient's outcome after hip fracture surgery.

ABSTRACT

The elderly population growth rate is extremely high in Korean society, and life expectancy is close to 85 years old for women and 80 for men as of people born in 2015. The future hip fracture prediction model of Korea shows that the elderly hip fracture rate will increase by 1.4 times by 2025, which will impose a serious socioeconomic burden on Korean society and become a key issue of public health management. The fracture liaison service (FLS) is defined adequate treatment and services for patients over 50 years old with fragility fractures, enabling systematic identification and decreasing the risk of subsequent osteoporotic fractures. In Korean society, the introduction of FLS, which is verified not only in the socioeconomic aspects but also in the treatment of patients, is thought to be essential. However, the challenges that need to be addressed in order to implement FLS include the lack of awareness regarding the necessity of this system, the lack of healthcare systems, and inadequate policies. In the future, further studies on the FLS and its clinical and socioeconomic effects for the Korean medical system will be necessary.

ABSTRACT

BACKGROUND: Because acute cholecystitis in elderly hip fracture is not easily distinguishable from other gastrointestinal symptoms and involves atypical clinical behaviors, it may not be diagnosed in the early stage. However, the exact incidences could not be reported. We utilized data from a nationwide claims database and attempted to assess the incidence of acute cholecystitis in elderly hip fracture patients and how cholecystitis affects mortality rates after hip fracture. METHODS: Study subjects were from the Korean National Health Insurance Service-Senior cohort. From a population of approximately 5.5 million Korean enrollees > 60 years of age in 2002, a total of 588,147 participants were randomly selected using 10% simple random sampling. The subjects included in this study were those who were over 65 years old and underwent surgery for hip fractures. RESULTS: A total of 15,210 patients were enrolled in the cohort as hip fracture patients. There were 7,888 cases (51.9%) of femoral neck fracture and 7,443 (48.9%) cases of hemiarthroplasty. Thirty-six patients developed acute cholecystitis within 30 days after the index date (30-day cumulative incidence, 0.24%). Four of the 36 acute cholecystitis patients (11.1%) died within 30 days versus 2.92% of patients without acute cholecystitis. In the multivariate-adjusted Poisson regression model, hip fracture patients with incident acute cholecystitis were 4.35 (adjusted risk ratio 4.35; 95% confidence interval, 1.66–11.37; P = 0.003) times more likely to die within 30 days than those without acute cholecystitis. CONCLUSION: Incidence of acute cholecystitis in elderly patients after hip fracture within 30 days after the index date was 0.24%. Acute cholecystitis in elderly hip fracture patients dramatically increases the 30-day mortality rate by 4.35-fold. Therefore, early disease detection and management are crucial for patients.

ABSTRACT

PURPOSE: This study was performed to analyze the potential impact of cement use and favorable pre-injury activity on clinical outcomes of bipolar hemiarthroplasty (BHA) compared with total hip arthroplasty (THA) in elderly patients with femoral neck fractures. MATERIALS AND METHODS: Systematic review and meta-analysis of 12 clinical studies (5 randomized controlled trials and 7 comparative studies). Subgroup analysis was performed based on type of fixation method (cemented vs. cementless) and in the patient with independent ambulation, respectively. RESULTS: A significantly higher dislocation rate was observed in patients treated with THA compared with those treated with BHA in individuals capable of independent ambulation before injury (odds ratio [OR], 0.17; 95% confidence interval [CI], 0.05–0.62; P=0.05, Z=1.98). Also, the dislocation rate was significantly higher in patients treated with cemented THA compared with those treated with cemented BHA (OR, 0.18; 95% CI, 0.05–0.62; P=0.006, Z=2.73). EQ-5D was significantly higher in those treated with cemented THA compared with patients treated with cemented BHA. Lastly, HHS was significantly higher in patients treated with cementless THA compared with those treated with cementless BHA. CONCLUSION: An increase in the dislocation rate was observed when THA was performed in elderly patients with femoral neck fracture and who were pre-injury independent walkers. In addition, cemented THA was associated with a higher dislocation rate compared with cemented BHA. However, the dislocation rate in those treated with cementless THA were similar to patients treated with cementless BHA. With regards to functional score, THA was superior to BHA in both cementless and cemented fixation.

ABSTRACT

PURPOSE: This study was conducted to compare cemented and cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures via meta-analysis and systematic review of relevant studies. MATERIALS AND METHODS: Systematic review and meta-analysis were performed on 31 available clinical studies; 19 of these studies used cemented stems, 12 used cementless stems, one used both types of stems, and two studies involved a comparative analysis of both stem types. RESULTS: There were statistically significant differences in rates of leg length discrepancy (LLD) greater than 1 cm between the cemented (event rate, 0.089) and cementless groups (event rate, 0.015 and 0.047; P=0.03). CONCLUSION: Cemented bipolar hemiarthroplasty and cementless bipolar hemiarthroplasty performed on elderly patients with unstable intertrochanteric fracture revealed similar mortality and complication rates; however, the rate of LLD greater than 1 cm was significantly higher in the cemented group compared with the cementless group.

ABSTRACT

We report a patient who experienced no function problems during the 5-year follow-up after a conservative treatment for minimally displaced acetabular fracture that developed as a result of the formation of physeal bar. According to the computed tomography, triradiate cartilage was fractured and minimally displaced, which was identified as a Salter Harris type II physeal injury. A fracture of the anterior wall of the acetabulum was also observed. It was judged as a stable fracture, and conservative treatment was performed. On the follow-up x-ray, the physeal bar was formed in the damaged triradiate cartilage. At 5-year follow-up, physeal injury of the triradiate cartilage has influenced the acetabular growth, resulting in acetabular dysplasia, pelvic asymmetry, hypoplasia of pubis, and widening of the tear drop. However, anteversion and inclination of the injured acetabulum were similar with those of the contralateral side. Our patient also did not complain of any hip discomfort.

ABSTRACT

BACKGROUND: Flatfoot deformity is a lever arm disease that incurs kinetic inefficiency during gait. The purpose of this study was to measure the degree of kinetic inefficiency by comparing the gait analysis data of a flatfoot group with a normal control group. METHODS: The patient group consisted of 26 children (21 males and 5 females) with symptomatic flatfoot. They were examined with gait analysis between May 2005 and February 2014. Exclusion criteria were patients with secondary flatfoot caused by neuromuscular disorders, tarsal coalition, vertical talus, or others. Patients' mean age was 9.5 years (range, 7 to 13 years). The gait analysis data of the study group and the normal control group were compared. RESULTS: The mean vertical ground reaction force (GRF) in the push-off phase was 0.99 for the patient group and 1.15 for the control group (p < 0.05). The mean ankle moment in the sagittal plane during the push-off phase was 0.89 for the patient group and 1.27 for the control group (p < 0.05). The mean ankle power in the sagittal plane during the push-off phase was 1.38 for the patient group and 2.52 for the control group (p < 0.05). The aforementioned results show that patients with pes planovalgus had a reduction of moment, power, and GRF in the push-off phase during gait. CONCLUSIONS: Symptomatic flatfeet had a moment inefficiency of 30% and power inefficiency of 45% during gait compared to feet with preserved medial longitudinal arches.

ABSTRACT

Demand for surgical management of adult spine deformity has increased due to a recent increase in the elder population, development of surgical techniques, and increased desire for a better quality of life. More surgeries led to more and various complications. Complications of surgery for adult spine deformity have been reported from 37% to 53% depending on the types of disease, cause, and patient. This rate is higher than complications from general spine surgeries. Complications of surgery for adult spine deformity include; infection, excessive bleeding, nerve injury, pseudarthrosis, adjacent segment disease, and iliac screw complication. Factors influencing these complications include; old age, diabetes, steroid use, and osteoporosis. Proximal junctional kyphosis (PJK) is an abnormal kyphosis at the proximal level of the instrument after spine deformity surgery. Risk factors for PJK include; injury of paravertebral muscles and posterior ligament complex, over- and under-correction of coronal sagittal imbalance, age older than 55 years, and osteoporosis. There is a high risk of unexpected complications during surgery for adult spine deformity. Patients with degenerative spine sagittal imbalance are more prevalent in Korea than in Western countries. They tend to be old, have underlying diseases and osteoporosis, making them susceptible to complications related to instrumentation. Postoperative satisfaction tends to be low thus surgeons need to take care when selecting surgical methods and fusion level.

ABSTRACT

PURPOSE: The authors evaluated the clinical and radiological results of ceramic on ceramic articulation cementless total hip arthroplasty using a large diameter head. MATERIALS AND METHODS: Seventy-two hips were followed for more than 2 years after ceramic on ceramic articulation cementless total hip arthroplasty using a 36 mm diameter head. The mean patient age was 62 years (range: 50-85), and the mean follow-up period was 35.3 months (range: 25-53). The Harris hip score, the postoperative inguinal pain and the thigh pain were analyzed clinically. The radiological results were assessed using various radiological indices. RESULTS: The mean Harris hip score improved from preoperative 57.5 points to postoperative 94.8 points. The postoperative mean flexion of hip was 109degrees (range: 100degrees-125degrees), external rotation was 42degrees (range: 35degrees-49degrees) and abduction was 35degrees (range: 30degrees-45degrees). There was one case of inguinal pain. Radiologically, all the stems demonstrated stable fixation without progressive subsidence of the stem or significant change in the cup obliquity. A radiolucent line was observed around the stem in 4 cases (5.6%) and around the cup in 2 cases (2.8%). Endosteal new bone formation was observed around the stem in 28 cases (38.9%) and around the cup in 26 cases (36.1%). There was no osteolysis around the stem or the cup. CONCLUSION: The short-term results of ceramic on ceramic cementless total hip arthroplasty using a large diameter head demonstrated satisfactory results.
