INTRODUCTION: The aim of this study was to elucidate the epidemiology and distribution of hand fractures in Singapore. METHODS: A total of 701 hand fractures in 596 patients aged 21 years and above from a single centre were reviewed from 2010 to 2011. Details regarding the patient demographics, occupation, mechanism of injury, associated injuries and treatment were obtained. RESULTS: Hand fractures were particularly significant in patients between the ages of 21 and 40 years 58.9% of the total cases. The relative risk of hand fractures in males was 5.5 times greater than that in females. The majority of hand fractures occurred at the workplace (47.7%), with crush injury being the main mechanism of injury (33.6%). The most common locations of hand fracture were the little finger ray (31.2%) and distal phalanges (37.7%). There were 170 cases that underwent surgical fixation, which accounted for 24.3% of all fractures. Fixation rate was similar for both closed and open fractures but was significantly higher in the proximal and middle phalanges compared to the distal phalanx and metacarpal ( P < 0.001). With regards to surgical fixation methods, wires were commonly used in either tuft fractures (100.0%) or intra-articular fractures (69.9%), whereas plates and screws were commonly used in shaft fractures (65.5%). CONCLUSION The most significant population that sustained hand fractures in Singapore are young to middle-aged males who are skilled manual workers. The most commonly involved ray and location of hand fractures are the little finger ray and the distal phalanges, respectively, as they are in a relatively more exposed location.

OBJECTIVE: To investigate the feasibility and effectiveness of the novel bone hook combined with finger-guided technique in the treatment of irreducible intertrochanteric femoral fractures in elderly. METHODS: Between January 2021 and August 2023, 23 elderly patients with irreducible intertrochanteric femoral fractures were treated with the novel bone hook combined with finger-guided technique. There were 10 males and 13 females; the age ranged from 68 to 93 years (mean, 76.2 years). The time from injury to operation ranged from 36 to 76 hours (mean, 51.2 hours). According to the classification standard proposed by TONG Dake et alin 2021, there were 10 cases of typeⅠA, 1 case of typeⅠB, 6 cases of type ⅡA, 4 cases of type ⅡB, and 2 cases of type ⅡC. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequences, and quality of fracture reduction were recorded. The fracture healing time and occurrence of postoperative complications were observed during follow-up. At last follow-up, the Harris scoring system was used to evaluate the hip joint function. RESULTS: The operation time was 42-95 minutes (mean, 52.1 minutes). The intraoperative blood loss was 40-420 mL (mean, 126.5 mL). Intraoperative fluoroscopy was performed 14-34 times (mean, 20.7 times). According to the criteria proposed by Chang et al, the quality of fracture reduction was rated as good in 20 cases and acceptable in 3 cases. All patients were followed up 6-20 months (mean, 10.2 months). X-ray film showed that all fractures healed with the healing time of 3.0-5.5 months (mean, 4.0 months). At last follow-up, the Harris score of the hip joint ranged from 82 to 97 points (mean, 90.4 points). Among them, 14 cases were rated as excellent and 9 cases as good. No complication such as coxa vara, cutting of the cephalomedullary nail, nail withdrawal, or nail breakage occurred during follow-up. CONCLUSION The treatment of elderly patients with irreducible intertrochanteric femoral fractures by using the novel bone hook combined with finger-guided technique can achieve high-quality fracture reduction and fixation, and has a good effectiveness.

OBJECTIVE: To analyze the demographic and clinical characteristics of inpatients with osteoporotic vertebral compression fractures (OVCF) and provide a basis for clinical prevention and treatment. METHODS: A retrospective analysis was performed on the clinical data of 744 inpatients diagnosed with OVCF between January 2017 and December 2021 who met the inclusion criteria. Among them, 146 were male and 598 were female, with age ranging from 50 to 95 years (mean, 69.37 years). The demographic characteristics (gender, age, ethnicity, occupation, regional distribution, urban-rural distribution, and seasonal incidence) and clinical features [causes of injury, history of vertebral fractures, smoking and drinking history in males, comorbidities (hypertension, diabetes, coronary atherosclerotic heart disease, cerebral infarction), body mass index (BMI), blood lipid levels, menopausal age in females, vertebral bone mineral density T-value, number of vertebral fractures, and fracture segment distribution] of OVCF patients were analyzed. Multiple linear regression was used to analyze the independent risk factors of vertebral osteoporosis. RESULTS: The demographic analysis indicated that female patients with OVCF were significantly younger than male patients ( P<0.05). Significant differences were observed in the age distribution of OVCF between males and females ( P<0.05), with the highest proportion of male patients in the 70-79 years group (37.0%) and the highest proportion of female patients in the 60-69 years group (40.0%). From 2017 to 2021, the age of onset for OVCF gradually increased, with a similar trend observed for both genders. The distribution of occupations between genders also showed significant differences ( P<0.05); with the top three occupations for males being farmers (48.6%), retirees (24.7%), and workers (13.7%), while for females, the leading occupations were farmers (51.5%), retirees (19.4%), and service workers (10.0%). Female OVCF patients had higher BMI, vertebral bone mineral density T-value, history of vertebral fractures, hypertension prevalence, and blood lipid levels compared to male patients ( P<0.05). No significant difference between the males and the females was found in ethnicity, seasonal distribution, regional distribution, urban-rural distribution, causes of injury, number of vertebral fractures, or prevalence of comorbidities (except hypertension) ( P>0.05). Among the 744 OVCF patients, a total of 1 309 vertebrae were involved, with 628 thoracic vertebrae (48.0%) and 681 lumbar vertebrae (52.0%). The most common fracture segments were L ₁ (22.5%), T ₁₂ (21.2%), followed by L ₂ (12.2%) and T ₁₁ (10.2%). No significant gender difference was observed in the distribution of fracture segments ( P>0.05). Multiple linear regression analysis indicated that older age, female, and lower BMI were independent risk factors for vertebral osteoporosis ( P<0.05). CONCLUSION The age of onset of OVCF patients is increasing year by year. The number of fractured vertebral bodies, age distribution of morbidity, occupational distribution, BMI, history of vertebral fracture, hypertension, and blood lipid levels are related to gender. The occurrence of OVCF is mainly in the thoracolumbar segment. The female, older age, and lower BMI are independent risk factors of osteoporosis.

OBJECTIVE: To investigate the effectiveness of 5G remote robotic surgery in the treatment of pelvic fractures. METHODS: A retrospective analysis was conducted on the clinical data of 160 patients with pelvic fractures admitted between July 2023 and June 2024 who met the selection criteria. Among these patients, 80 underwent internal fixation surgery with the assistance of 5G remote robotic surgery (5G group), while 80 received local robotic surgical assistance (control group). Baseline characteristics, including gender, age, body mass index, disease duration, cause of injury, and fracture classification, were compared between the two groups, and no significant difference was found ( P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, maximum residual displacement postoperatively, quality of fracture reduction, incidence of complications, Majeed pelvic function score and classification at last follow-up were recorded and compared between the two groups. RESULTS: In the 5G group, 180 screws were implanted during surgery, while 213 screws were implanted in the control group. The 5G group demonstrated significantly reduced intraoperative blood loss and shorter incision length compared to the control group ( P<0.05). No significant difference was observed between the two groups in terms of operation time or hospital stay ( P>0.05). Radiographic evaluation revealed excellent and good reduction rates of 98.8% (79/80) in the 5G group and 97.5% (78/80) in the control group, while excellent and good screw placement accuracy rates were 98.3% (177/180) in the 5G group and 95.8% (204/213) in the control group. No significant difference was found between the two groups in maximum residual displacement, reduction quality, or screw placement accuracy ( P>0.05). All patients were followed up 7-16 months (mean, 11.3 months), with no significant difference in follow-up duration between the groups ( P>0.05). No perioperative or follow-up complication, such as wound infection, iatrogenic fractures, iatrogenic neurovascular injury, screw loosening or breakage, or nonunion, were observed in either group. The control group exhibited a worse degree of gait alteration compared to the 5G group ( P<0.05), while no significant difference was found in incidences of squatting limitation or persistent pain ( P>0.05). At last follow-up, no significant difference was observed between the groups in Majeed pelvic function scores or grading ( P>0.05). CONCLUSION Compared with the local surgery group, 5G remote robotic surgery supported by remote expert technical guidance demonstrated smaller incision lengths, less intraoperative blood loss, and fewer postoperative complications, and was shown to be a precise, minimally invasive, safe, and reliable surgical method.

OBJECTIVE: To compare the effectiveness and shoulder function of reverse total shoulder arthroplasty (RTSA) and open reduction and internal fixation (ORIF) in the treatment of Neer three/four-part proximal humeral fractures in the elderly. METHODS: Randomized controlled analysis was conducted on 68 patients over 70 years old with Neer three/four-part proximal humeral fractures treated with RTSA or ORIF between January 2020 and June 2022. The patients were randomly divided into RTSA group ( n=32) and ORIF group ( n=36). There was no significant difference ( P>0.05) in the baseline data such as age, gender, body mass index, injured side, Neer classification, and preoperative Charlson comorbidity index, visual analogue scale (VAS) score, Constant shoulder score, Oxford shoulder score (OSS), and hemoglobin (Hb). The operation time, intraoperative blood loss, reduction of Hb on the 3rd day after operation, hospital stay, total cost of hospitalization, complication incidence, range of motion of shoulder joint at 2 years after operation, VAS score before operation and at 5 days and 1 month after operation, Constant shoulder score and OSS score before operation and at 2 years after operation, and imaging results during follow-up were recorded and compared between the two groups. RESULTS: Compared with the ORIF group, the RTSA group had longer operation time, less intraoperative blood loss, and higher total cost of hospitalization ( P<0.05). There was no significant difference in Hb reduction on the 3rd day after operation between the two groups ( P>0.05). The VAS scores significantly improved in both groups at 5 days and 1 month after operation ( P<0.05), but there was no significant difference between the two groups ( P>0.05). All patients were followed up 26-35 months, with an average of 31.2 months. In the RTSA group, there were 2 cases of poor healing of superficial incision and 1 case of transient nerve injury. There was no complication such as bone resorption around the prosthesis, lucent band, prosthesis loosening, or periprosthetic fracture in all patients. In the ORIF group, there was 1 case of poor healing of superficial incision, 3 cases of nonunion of fracture, 1 case of arthritis secondary to humeral head necrosis, and 1 case of bone absorption of large tuberosity, and no displacement or fracture failure of internal fixation was found in all patients. There was no significant difference in the incidence of complications [9.4% (3/32) vs 16.7% (6/36)] between the two groups [ OR (95% CI): 0.828 (0.171, 4.014), P=0.814]. In the RTSA group, 28 cases were graded 0 and 4 cases were graded 1 at 2 years after operation. Constant and OSS scores of RTSA group were significantly better than those of ORIF group ( P<0.05). The Constant score was significantly better than ORIF group in activity and strength, range of motion, lifting, abduction, and external rotation ( P<0.05), and there was no significant difference in pain, daily function, and internal rotation between the two groups ( P>0.05). The RTSA group had a significantly greater range of motion in lifting, abduction, and external rotation than ORIF group ( P<0.05), but there was no significant difference in internal rotation between the two groups ( P>0.05). CONCLUSION Application of RTSA as the initial treatment of Neer three/four-part proximal humeral fractures in the elderly can achieve better rehabilitation of joint activity and lower risk of early reoperation, and improve the quality of life of elderly fracture patients. However, the difficulty of revision and the high cost of treatment require the surgeon to pay full attention and strictly grasp the indications.

OBJECTIVE: To compare the effectiveness of early versus delayed closed reduction and percutaneous Kirschner wire fixation in the treatment of pediatric supracondylar humerus fractures. METHODS: A retrospective analysis was conducted on 468 children with supracondylar humerus fractures, who were admitted between January 2020 and December 2023 and met the inclusion criteria. Among them, 187 children were treated during 12 hours after injury (early operation group) and 281 were treated after 12 hours (delayed operation group). There was no significant difference between the two groups ( P>0.05) in the gender, age, injury mechanism, fracture side and type, while there was significant difference in interval from injury to operation ( P<0.05). The operative outcomes, including the operation time, intraoperative blood loss, the length of hospital stay, fracture healing time, elbow function assessed by Flynn criteria at 3 months after operation, and complications, were compared. RESULTS: Compared to the delayed operation group, the early operation group demonstrated significantly shorter operation time and less intraoperative blood loss ( P<0.05). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). All children were followed up 3-12 months. The follow-up time was (6.7±2.9) months in the early operation group and (6.9±2.8) months in the delayed operation group, showing no significant difference between the two groups ( P>0.05). There was no significant difference in the fracture healing time between the two groups ( P>0.05). At 3 months after operation, the early operation group exhibited superior Flynn elbow functional outcomes to the delayed operation group ( P<0.05). In the early operation group, there was 1 case of fracture non-union and 3 cases of cubital varus deformity after operation. In the delayed operation group, there was 1 case of nerve injury, 7 cases of fracture non-union, and 12 cases of cubital varus deformity after operation. There was significant difference in the incidence of complications between the two groups ( P<0.05). One case of the early operation group and 10 cases of the delayed operation group underwent secondary operation, showing no significant difference in the incidence of secondary operation between the two groups ( P>0.05). CONCLUSION For pediatric supracondylar humerus fractures, early closed reduction and percutaneous Kirschner wire fixation can reduce operation time, minimize intraoperative blood loss and postoperative complications, and improve the functional recovery compared to delayed operation.

OBJECTIVE:  To estimate the population attributable disease burden (PAD) of low bone mineral density (LBMD) related fractures (fragility fractures) among Chinese people over 50 years old from 1990 to 2023, using data from the Global Burden of Disease Study 2023 (GBD 2023), and to provide evidence for prevention strategies and health resource allocation. METHODS:   Based on the GBD 2023, the LBMD summary exposure values (SEV), fracture incidence, years lived with disability (YLDs), and LBMD-related falls YLDs of Chinese people over 50 years old from 1990 to 2023 were extracted. PAD was calculated with population attributable fraction (PAF), and an entropy-weight method was applied to evaluate the contribution of individual fracture sites. Temporal trends and sex differences were examined with Joinpoint regression. RESULTS:  From 1990 to 2023, the age-standardized SEV of LBMD in people over 50 years old showed an overall decline [average annual percent change (AAPC)=-0.564%]. Age-standardized fracture incidence, fracture YLDs rate, and LBMD-related falls YLDs rate all exhibited W-shaped upward trends (AAPC=1.045%, 0.296%, and 0.724%, respectively). PAF-based estimates indicated that LBMD-attributable fracture incidence likewise increased in a "W-shaped" manner (AAPC=0.558%), whereas the corresponding YLDs rate showed an overall W-shaped decline (AAPC=-0.193%). In international comparison, China and the global average displayed broadly concordant directions of change, with greater volatility in China and a progressive narrowing of the gap after 2015. Regarding sex differences, fracture YLDs rates were consistently higher in the males, whereas the other burden indicators were higher in the females; the temporal patterns were similar in both sexes. Entropy weight method identified hip fractures as contributing most to incidence (weight 0.133), and pelvic fractures as the largest contributor to YLDs rate (weight 0.115). CONCLUSION Since 1990, the LBMD attributable fracture burden in China's older population has risen, with female and hip or pelvic fractures bearing the heaviest load. Strengthened osteoporosis screening, improved insurance coverage, and targeted health education are urgently needed to curb further increases in disease burden.

OBJECTIVE: To analyze the disease burden of pelvic fractures at the global, regional, and national levels from 1990 to 2023 using data from the 2023 Global Burden of Disease Study (GBD), and to predict the disease burden through 2050. METHODS: Leveraging data from the GBD 2023, this study investigated the disease burden of pelvic fractures across 204 countries and regions. Assessment indicators included incidence rate, prevalence rate, and years lived with disability (YLDs). The Joinpoint regression model was employed to analyze trends in pelvic fracture burden from 1990 to 2023, while the average annual percentage change (AAPC) was used to quantify this temporal trend. The relationship between the socio-demographic index and pelvic fracture burden was evaluated. Furthermore, the long short-term memory (LSTM) model was applied to predict trends in pelvic fracture burden through 2050. RESULTS: In 2023, the estimated number of new pelvic fracture cases globally was 7 479 884 [95% uncertainty interval ( UI): 5 293 401-10 611 876], representing a 42.74% increase from 1990. In the same year, the number of prevalent pelvic fracture cases and YLDs were 23 007 508 (95% UI: 21 021 518-25 327 165) and 3 909 228 person-years (95% UI: 2 725 498-5 194 385), respectively. Additionally, age-standardized rates exhibited an opposing downward trend. Significant disparities in the disease burden of pelvic fractures were identified across different age groups, genders, and social contexts. According to predictions from the LSTM model, the global age-standardized incidence rate (ASIR) of pelvic fractures will be approximately 88.44 per 100 000 persons by 2050, while the total number of incident cases will rise to 8 547 095. CONCLUSION Although the overall incidence rate, prevalence rate, and YLDs of pelvic fractures have exhibited an upward trend over the past three decades, the ASIR, age-standardized prevalence rate (ASPR), and age-standardized years of life lost rate (ASYR) have shown a downward trend. It is predicted that over the upcoming 26-year period, the age-standardized rate of disease burden due to pelvic fractures will further decrease, while the number of incident cases and prevalent cases will continue to exhibit an upward trend. Formulating more targeted disease prevention strategies is critical to addressing disparities across genders, regions, and other dimensions, and to mitigating the burden of pelvic fractures.

PURPOSE: To comprehensively analyze the geographic and temporal trends of foot fracture, understand its health burden by age, sex, and sociodemographic index (SDI), and explore its leading causes from 1990 to 2019. METHODS: The datasets in the present study were generated from the Global Burden of Diseases Study 2019, which included foot fracture data from 1990 to 2019. We extracted estimates along with the 95% uncertainty interval (UI) for the incidence and years lived with disability (YLDs) of foot fracture by location, age, gender, and cause. The epidemiology and burden of foot fracture at the global, regional, and national level was exhibited. Next, we presented the age and sex patterns of foot fracture. The leading cause of foot fracture was another focus of this study from the viewpoint of age, sex, and location. Then, Pearson's correlations between age-standardized rate (ASR), SDI, and estimated annual percentage change were calculated. RESULTS: The age-standardized incidence rate was 138.68 (95% UI: 104.88 - 182.53) per 100,000 persons for both sexes, 174.24 (95% UI: 134.35 - 222.49) per 100,000 persons for males, and 102.19 (95% UI: 73.28 - 138.00) per 100,000 persons for females in 2019. The age-standardized YLDs rate was 5.91 (95% UI: 3.58 - 9.25) per 100,000 persons for both genders, 7.35 (95% UI: 4.45 - 11.50) per 100,000 persons for males, and 4.51 (95% UI: 2.75 - 7.03) per 100,000 persons for females in 2019. The global incidence and YLDs of foot fracture increased in number and decreased in ASR from 1990 to 2019. The global geographical distribution of foot fracture is uneven. The incidence rate for males peaked at the age group of 20 - 24 years, while that for females increased with advancing age. The incidence rate of older people was rising, as younger age incidence rate declined from 1990 to 2019. Falls, exposure to mechanical forces, and road traffic injuries were the 3 leading causes of foot fracture. Correlations were observed between ASR, estimated annual percentage change, and SDI. CONCLUSIONS The burden of foot fracture remains high globally, and it poses an enormous public health challenge, with population aging. It is necessary to allocate more resources to the high-risk populations. Targeted realistic intervention policies and strategies are warranted.

PURPOSE: We carried out the study aiming to explore and analyze the risk factors, the distribution of pathogenic bacteria, and their antibiotic-resistance characteristics influencing the occurrence of surgical site infection (SSI), to provide valuable assistance for reducing the incidence of SSI after traumatic fracture surgery. METHODS: A retrospective case-control study enrolling 3978 participants from January 2015 to December 2019 receiving surgical treatment for traumatic fractures was conducted at Tangdu Hospital of Air Force Medical University. Baseline data, demographic characteristics, lifestyles, variables related to surgical treatment, and pathogen culture were harvested and analyzed. Univariate analyses and multivariate logistic regression analyses were used to reveal the independent risk factors of SSI. A bacterial distribution histogram and drug-sensitive heat map were drawn to describe the pathogenic characteristics. RESULTS: Included 3978 patients 138 of them developed SSI with an incidence rate of 3.47% postoperatively. By logistic regression analysis, we found that variables such as gender (males) (odds ratio (OR) = 2.012, 95% confidence interval (CI): 1.235 - 3.278, p = 0.005), diabetes mellitus (OR = 5.848, 95% CI: 3.513 - 9.736, p < 0.001), hypoproteinemia (OR = 3.400, 95% CI: 1.280 - 9.031, p = 0.014), underlying disease (OR = 5.398, 95% CI: 2.343 - 12.438, p < 0.001), hormonotherapy (OR = 11.718, 95% CI: 6.269 - 21.903, p < 0.001), open fracture (OR = 29.377, 95% CI: 9.944 - 86.784, p < 0.001), and intraoperative transfusion (OR = 2.664, 95% CI: 1.572 - 4.515, p < 0.001) were independent risk factors for SSI, while, aged over 59 years (OR = 0.132, 95% CI: 0.059 - 0.296, p < 0.001), prophylactic antibiotics use (OR = 0.082, 95% CI: 0.042 - 0.164, p < 0.001) and vacuum sealing drainage use (OR = 0.036, 95% CI: 0.010 - 0.129, p < 0.001) were protective factors. Pathogens results showed that 301 strains of 38 species of bacteria were harvested, among which 178 (59.1%) strains were Gram-positive bacteria, and 123 (40.9%) strains were Gram-negative bacteria. Staphylococcus aureus (108, 60.7%) and Enterobacter cloacae (38, 30.9%) accounted for the largest proportion. The susceptibility of Gram-positive bacteria to Vancomycin and Linezolid was almost 100%. The susceptibility of Gram-negative bacteria to Imipenem, Amikacin, and Meropenem exceeded 73%. CONCLUSION Orthopedic surgeons need to develop appropriate surgical plans based on the risk factors and protective factors associated with postoperative SSI to reduce its occurrence. Meanwhile, it is recommended to strengthen blood glucose control in the early stage of admission and for surgeons to be cautious and scientific when choosing antibiotic therapy in clinical practice.
