INTRODUCTION
Complex dorsal metacarpophalangeal joint (MCPJ) dislocations are uncommon injuries that mainly affect the index finger and are typically caused by a fall on an outstretched hand. It is exceptional for complex MCPJ dislocation to coexist with a distal fracture of the corresponding metacarpal bone.
PRESENTATION OF THE CASE
The authors report a case of a 23-year-old man presented to the emergency, with a complex dorsal metacarpophalangeal joint dislocation of the index associated with a distal metacarpal fracture confirmed by imaging. The patient had an open reduction and internal fixation of the proximal metacarpal fracture. The results were satisfying.
DISCUSSION
Dorsal MCP joint dislocations are rare, primarily affecting the index and little fingers, and are typically caused by a fall on an outstretched hand. Complex dislocations, characterized by irreducibility, involve structures forming a "noose" around the metacarpal head. Fractures associated with these dislocations are uncommon. Early diagnosis is crucial for better long-term functional outcomes. Radiographic imaging, including three different views, is necessary for accurate diagnosis. Surgery is usually required, with different approaches depending on the case. Arthroscopic techniques can be used when reduction is challenging. Timely surgical intervention yields the best results. Stiffness, osteoarthritis, osteonecrosis, and growth arrest in pediatric cases are the main complications.
CONCLUSION
Complex dorsal metacarpophalangeal joint (MCPJ) dislocations are rare. Open reduction is typically necessary for optimal outcomes. Complications such as stiffness, osteoarthritis can arise, emphasizing the importance of accurate diagnosis and appropriate management.

OBJECTIVE
Metacarpal fractures are one of the most common orthopedic injuries seen in emergency departments. Despite this, only a few data have been published about the epidemiology of metacarpal fractures. Simple radiographs are the standard imaging modality used to diagnose boxer fractures and determine the degree of angulation. Fractures and angulations should be identified by anteroposterior and lateral radiographs. The aim of this study was to follow the healing after closed reduction of fifth metacarpal neck fractures in a pediatric population using the QuickDASH score to determine whether it results in clinically significant improvement.
SUBJECTS AND METHODS
Between 2020 and 2022, our clinical record database for all metacarpal fractures treated at our institution was searched retrospectively every month. Children aged 18 years and younger with fifth metacarpal neck fractures treated with closed reduction and immobilization in our tertiary care emergency clinic were retrospectively reviewed.
RESULTS
52 pediatric patients were included in the study. The mean age at the time of injury was 14.04 years (SD=2.10, range=10-18 years). 92.30% (n=48) of the patients were male, and 7.70% (n=4) were female.
CONCLUSIONS
Accurate diagnosis and appropriate treatment are crucial in the management of childhood fifth metacarpal fractures to ensure proper healing, prevent long-term complications, and facilitate optimal functional recovery.

Fractures occurring in the distal radius and ulna of toy breed dogs pose distinctive challenges for veterinary practitioners, requiring specialized treatment approaches primarily based on anatomical features. Finite Element Analysis (FEA) was applied to conduct numerical experiments to determine stress distribution across the bone. This methodology offers an alternative substitute for directly investigating these phenomena in living dog experiments, which could present ethical obstacles. A three-dimensional bone model of the metacarpal, carpal, radius, ulna, and humerus was reconstructed from Computed Tomography (CT) images of the toy poodle and dachshund forelimb. The model was designed to simulate the jumping and landing conditions from a vertical distance of 40 cm to the ground within a limited timeframe. The investigation revealed considerable variations in stress distribution patterns between the radius and ulna of toy poodles and dachshunds, indicating notably elevated stress levels in toy poodles compared to dachshunds. In static and dynamic stress analysis, toy poodles exhibit peak stress levels at the distal radius and ulna. The Von Mises stresses for toy poodles reach 90.07 MPa (static) and 1,090.75 MPa (dynamic) at the radius and 1,677.97 MPa (static) and 1,047.98 MPa (dynamic) at the ulna. Conversely, dachshunds demonstrate lower stress levels for 5.39 MPa (static) and 231.79 MPa (dynamic) at the radius and 390.56 MPa (static) and 513.28 MPa (dynamic) at the ulna. The findings offer valuable insights for modified treatment approaches in managing fractures in toy breed dogs, optimizing care and outcomes.

STATEMENT OF THE PROBLEM
Bone age is a more accurate assessment for biologic development than chronological age. The most common method for bone age estimation is using Pyle and Greulich Atlas. Today, computer-based techniques are becoming more favorable among investigators. However, the morphological features in Greulich and Pyle method are difficult to be converted into quantitative measures. During recent years, metacarpal bones and metacarpophalangeal joints dimensions were shown to be highly correlated with skeletal age.
PURPOSE
In this study, we have evaluated the accuracy and reliability of a trained neural network for bone age estimation with quantitative and recently introduced related data, including chronological age, height, trunk height, weight, metacarpal bones, and metacarpophalangeal joints dimensions.
MATERIALS AND METHOD
In this cross sectional retrospective study, aneural network, using MATLAB, was utilized to determine bone age by employing quantitative features for 304 subjects. To evaluate the accuracy of age estimation software, paired t-test, and inter-class correlation was used.
RESULTS
The difference between the mean bone ages determined by the radiologists and the mean bone ages assessed by the age estimation software was not significant ( Value= 0.119 in male subjects and = 0.922 in female subjects). The results from the software and radiologists showed a strong correlation -ICC=0.990 in male subjects and ICC=0.986 in female subjects (< 0.001).
CONCLUSION
The results have shown an acceptable accuracy in bone age estimation with training neural network and using dimensions of bones and joints.

Introduction Understanding the incidence and epidemiology can inform clinicians and policymakers about the population's needs. Our study reports on upper limb fractures treated at a major trauma center over 7.5 years. Methods We collected data on fracture locations, age, gender, Charlson Comorbidity index (CCI), and treatment options of all upper limb fractures treated at a Level I Trauma Centre from January 1, 2015 to June 30, 2022. Humerus, radius, and ulna fractures were each classified as proximal, diaphyseal, and distal. Results About 9,915 patients sustained 12,790 fractures, given an overall incidence of 303.2 fractures per 100,000 patients per year. The most common fracture site was the distal radius (60.1 fractures per 100,000 patients per year, whereas carpal and metacarpal bones had the lowest incidence. The mean age and CCI were 46.4 years and 1.54, respectively. 58.1% of patients were male. All bone fractures distal to the elbow were associated with an age younger than the mean (all p<0.001), with humerus fracture patients having the oldest mean age (54.6 years). Compared to the mean gender ratio, except for ulna (no association), humerus (55% female), and radius (51% female), all other locations showed significantly higher incidences of males (all p<0.001). When plotting the incidence based on the age of injury, the entire cohort, along with radius and ulna fracture subgroups, demonstrated a bi-peak distribution. This pattern revealed that younger males and older postmenopausal females had the highest incidence rates. Conclusion To our knowledge, this represents the first study of this type in the UK since 2006. We sought to elucidate relative incidence and demographic associations with fractures to highlight changing population needs and allow policymakers and services at a regional and national level to operate with up-to-date information.

Repetitive microtrauma can lead to trapezoid and second metacarpal stress fractures in racket sport players. Nontraumatic trapezoid stress fractures are rare and difficult to diagnose. To our knowledge, only 3 cases had been reported as of May 2023. We report the fourth case of a nontraumatic sports-related trapezoid stress fracture and only the second case in a tennis player. A 29-year-old professional and right hand-dominant male tennis player presented with right hand and wrist pain for 3 weeks. He complained of dorsal wrist tenderness proximal to the base of the second metacarpal that was exacerbated by extension of the index finger. Initial radiographs were normal, but magnetic resonance imaging of the wrist showed a stress fracture of the trapezoid bone and base of the second metacarpal. The patient was treated conservatively with a wrist brace, cessation of sports activities, and modification of his training routine. The patient was asymptomatic at 1-year follow-up. This case highlights the relationship between trapezoid and second metacarpal stress fractures in athletes. A high index of suspicion for trapezoid stress fractures should be maintained and included in every differential diagnosis for athletes, especially racket sport players presenting with wrist pain. To avoid future injuries, clinicians should not only treat the fracture but also address the risk factors predisposing to this injury.

BACKGROUND
Synovial sarcoma is a rare soft tissue sarcoma, with incidences of 0.81/1,000,000 in children and 1.42/1,000,000 in adults. It is most commonly found in soft tissue and rarely in bone. It often has a slow growth pattern and a benign radiologic appearance.
CASE PRESENTATION
This study reports a case of metacarpal synovial sarcoma occurring in the hand-wrist of a 32-year-old Iranian man presented with the chief complaint of a lump on the dorsal ulnar side of his left hand and wrist. Initially, the first physician suspected the case to be a ganglion cyst. After two months of conservative treatment, the size of the lesion gradually increased. Magnetic resonance imaging (MRI) was performed and after an excisional biopsy and a postoperative histological analysis, the tumor was identified as a synovial sarcoma. The patient underwent a scheduled surgical procedure. Unfortunately, he had poor follow-ups and brought the pathologic results two months later when, the tumor had incredible growth, which makes this presentation rare.
CONCLUSIONS
Since early diagnosis can lead to higher survival rates, this report increases doctors' awareness of this extremely malignant tumor that is rarely seen.

Metacarpophalangeal joint region pain is a common cause of lameness in racehorses. Radiological abnormalities in the sagittal ridge (SR) of the third metacarpal bone have been associated with joint effusion, lameness and reduced sales prices. The aims were to describe computed tomographic (CT) appearance of the SR in racehorses, and to document the progression of these findings over three assessments. Forty yearlings were enrolled at the first examination (time 0). Re-examinations were performed twice, approximately six months apart on 31 (time 1) and 23 (time 2) horses, respectively. Computed tomographic examinations of both metacarpophalangeal regions were performed with the horses in a standing position. Computed tomographic reconstructions were analysed subjectively and objectively. The mean Hounsfield Unit values (Hus) of eight radial segments and location, size and shape of hypoattenuating lesions were recorded. Mean Hus at time 1 were higher than at time 0. There was no difference between mean HU at times 1 and 2. The mean HU values of the dorsal half were higher in the right forelimbs and in fillies. Hypoattenuation was identified in 33/80 (41.3%) limbs at time 0, in 22/62 (35.5%) limbs at time 1 and in 14/46 (30.4%) limbs at time 2. All hypoattenuations were located in the dorsodistal aspect of the SR. The most common shapes were hypoattenuating lesions elongated proximodistally and those extending towards trabecular bone. An increase in attenuation of the SR occurred in the first six months of training. Hypoattenuating lesions could decrease in size and could resolve during early training. In this population, these lesions were not associated with lameness.

'I just need to find out if I had broken something or not.' A qualitative descriptive study into patient decisions to present to an Emergency Department with a simple fracture.
Background To investigate what factors contribute to a working age adult with a simple fracture seeking care in an Australian metropolitan Emergency Department (ED) Methods In this Qualitative Descriptive study, we interviewed ED patients with simple fractures including 5th metacarpal, 5th metatarsal, toe, radial head and clavicle fractures. Results We interviewed 30 patients aged 18-65. Two thirds of participants were aware they might have a minor injury. Many were well informed health consumers and convenience was the most important decision-making factor. Participants focussed on organising imaging, diagnosis and immobilisation. This sequence of care was often perceived as more complex and inefficient in primary care. ED was trusted and preferred to urgent primary care with an unknown doctor. Some patients defaulted to attending ED without considering alternatives due to poor health system knowledge or from escalating anxiety. Conclusions ED is safe, free and equipped to manage simple and complex injuries. Patients would attend primary care if comprehensive fracture management was easily accessible from a trusted clinician. To effectively divert simple fracture presentations from ED, primary care requires collocated imaging, imaging interpretation, orthopaedic expertise, and fracture management resources. Services need to operate 7 days a week and must have accessible 'urgent' appointments.

Meta-Analysis
PURPOSE
This review was performed to systematically compare the effectiveness and safety of the first dorsal metacarpal artery flaps (FDMAF) and reverse homodigital dorsal flaps (RHDF) for thumb reconstruction.
METHODS
All literatures, which compared FDMAF versus RHDF for thumb reconstruction, were acquired through a comprehensive search in multiple databases from inception until 31st August 2022. A meta-analysis was performed using the Cochrane Collaboration's RevMan 5.4 software.
RESULTS
A total of 19 articles were retrieved, comprising 396 patients in the FDMAF group and 423 patients in the RHDF group. The pooled estimates suggested that there were no significant differences in venous congestion, complications about flap necrosis and reduced range of motion (ROM) of thumb, static 2-point discrimination (S-2PD) between the two groups. On the other hand, patients in the RHDF group had less vascular crisis (odds ratio [OR] = 3.15, 95%CI, 1.31-7.56), complications about poor cortical reorientation (OR = 440.02, 95%CI, 91.97-2105.27) and higher satisfaction rate (OR = 0.56, 95% CI, 0.33-0.96) than those in the FDMAF group.
CONCLUSIONS
The two surgical procedures were both safe and reliable since no significant differences were found in flap necrosis between the two groups. However, the patients in the RHDF group had less complications about vascular crisis, poor cortical reorientation and higher satisfaction rate. Accordingly, we thought RHDF may be more superior for thumb reconstruction than FDMAF.
