Abstract
Introduction: Skeletal involvements are less reported in tuberculosis and even less likely observed in fingers. Fingers are rarely involved in adults and it often has been reported in children under 5 years old. Most likely, a recent condition in adult patients is required to provoke reactivation of bacilli lodged in the bone during the original mycobacteremia of primary infection.

Abstract
Femoral neck stress fractures are rare and encompass 5% of all stress fractures among the young people. The bilateral cases are very rare. Coxa vara deformity and morbid obesity are some of the predisposing factors for bilateral stress fractures. The decline of neck-shaft angle will result in an increase and concentration of stress force in femoral neck giving rise to fracture. This report introduced a 35-year-old man with severe coxa vara deformity with an angle of 100 neck-shaft who had a bilateral femoral neck stress fracture and severe obesity [body mass index (BMI) >; 35 kg/m2]. The femoral neck stress fracture was a tension-type occurred due to stress in coxa vara. Based on laboratory findings, his vitamin D deficiency was severe (8.9 ng/mL) but his PTH and phosphorus levels were normal. Regarding vitamin D deficiency and previous femoral deformity, the possibility of osteomalacia in adolescence period was raised. Bilateral valgus sub-trochanteric osteotomy and fixation with a dynamic hip screw (DHS) were performed. After three months, the patient restored his walking ability and weight bearing. Valgus sub-trochanteric osteotomy and fixation with DHS are useful methods in coxa vara deformity concomitant with stress fractures and can modify the neck-shaft angle.

Abstract
Introduction: Pseudoaneurysm, accompanied by penetrating trauma in the forearm, is rarely reported. Considering that clinical examination is not standard in these cases, clinical suspicion and application of suitable diagnostic modalities would be promising and helpful. Most of these patients were referred to the emergency units but were not correctly diagnosed.
Case Presentation: In this report, we present a 22-year-old patient with increasing pain because of a stab wound to forearm 10 days after the first referral to the emergency unit. A pseudoaneurysm was suspected in posterior interosseous of the radial artery because of the persistent pain and palpation of mass.
Conclusions: The results of bedside ultrasound in the emergency unit and CT angiography revealed pseudoaneurysm in posterior interosseous of the radial artery. The surgical treatment was the resection of the lesion and posterior interosseous ligature. All symptoms of the patient were resolved in a 2-months follow-up. Post-traumatic upper extremity pseudoaneurysm can show its signs and symptoms after a long time.

Abstract
Introduction: Radial neck fracture is one of the rare traumas in the upper extremity among the children accounting for 5%-10% of the pediatric elbow injuries. The valgus strain-induced radial neck displacement often ranges from 10° to 90. Rotational displacement with 180° rotation is very rare.
Case Presentation: In this case report, we present a 6-year-old child who had radial neck fracture with 180 rotation and joint surface tilt toward the distal direction after falling on her outstretched hand. The close reduction was conducted under the fluoroscopic guide and the radial neck-shaft was restored with 15 angulation. The elbow was immobilized by a long forearm cast for 3 weeks. Based on conventional radiography taken after 3 weeks, a complete union was achieved. Six-month follow-up showed no radial growth disturbance and radial head avascular necrosis.
Conclusions: The radial head could be displaced in the form of 180° rotation during the radial neck fracture. In this regard, careful attention to the joint surface is important to minimize the lateral displacements or angulation and to avoid any misdiagnosis. The closed reduction was a successful treatment and caused no complications.

Abstract
Background: The anterior cruciate ligament surgery commonly uses a hamstring tendon. The hamstring grafts are usually prepared by wrapping in a wet gauze under tension.
Objectives: The placement of a hamstring tendon in a dry gauze affects the size of the graft, without any change in its collagen volume. The present study aimed to prove that the preparation method could affect the hamstring graft width.
Methods: A total number of 32 patients who had undergone the anterior cruciate ligament reconstruction were enrolled in this analytical descriptive study. Initially, the width of the 4-layered extracted graft was measured using the sizer system, after placement under traction. Then, 16 patients were operated on, based on the dry gauze preparation method, and the other 16, based on the wet gauze preparation method. The grafts were remeasured after traction. Six months after the surgery, all patients received a clinical evaluation, in which the integrity of the graft was evaluated based on clinical criteria.
Results: The Mean±SD width of the 4-layered extracted grafts was 7.44±0.54 mm and 7.41±0.33 mm in the dry gauze and wet gauze groups, respectively. However, these values did not significantly differ (P=0.96). After traction, the Mean±SD graft width of the dry gauze group was reduced to 6.97±0.62 mm. The traction led to no change in the graft width of the wet gauze group. The changes in the graft size significantly differed between the two groups (P=0.032). Moreover, 4 patients (25%) exhibited no certain endpoint in the Lachman test, also, the pivot shift-test was positive in 5 patients (31.2%).
Conclusion: The hamstring graft preparation technique affects the tunnel graft size. Besides, the use of dry gauzes procures the need for a narrower tunnel in the tibia and femur.

Abstract
Fractures of the talus bone in pediatric patients are exceptionally infrequent, primarily attributed to the greater flexibility of immature skeletal structures compared to fully developed bones in adults. Therefore, limited research exists regarding the long-term outcomes, clinical aspects, and appropriate treatment of these fractures in pediatrics. An eight-year-old male patient presented with swelling and pain in his right ankle after falling into a 10-meter well. Twelve days later, he sought medical attention and was examined by an orthopedic surgeon. X-ray examination showed a fracture in the head of the talus. Consequently, the fracture was reduced by open surgery and then stabilized with two Herbert screws. The patient’s progress was monitored regularly and subsequent imaging studies showed complete fracture healing. Within six months after the operation, the patient can resume his sporting activities before injury without any complications. Injuries to the head of the talus in childhood should be considered as fractures in the transitional phase. The open reduction coupled with internal fixation aims to decrease the occurrence of osteoarthritis and malalignment. In such cases, it is recommended to conduct a computed tomography (CT) scan for comprehensive evaluation and treatment planning.

Abstract
Background: Elbow fractures are among the most common injuries in children. While elbow fractures are rarely life-threatening, their significance lies in potential complications. Therefore, accurate and timely diagnosis and appropriate treatment are essential for elbow fractures. Identifying the frequency of pediatric visits with elbow injuries, categorized by fracture type and treatment method, is necessary for optimizing treatment planning.
Objectives: This study addresses the knowledge gap regarding pediatric elbow injuries by investigating the frequency, fracture types, and treatment methods among children seeking medical attention at Shafa Yahyaiyan Orthopedic Hospital, Tehran, Iran.
Methods: This cross-sectional, descriptive study comprised children under 18 presenting to the Emergency Department of Shafa Yahyaiyan Orthopedic Hospital due to elbow injuries from September 20, 2020, to March 20, 2021. Demographic, clinical, and radiologic variables were collected using medical records. The statistical analysis was performed using the SPSS software, version 22, with a significance level set at 0.05.
Results: A total of 507 pediatric cases with elbow injuries were analyzed, including 54% males. The average age of the cohort was 3.44±4.73 years. Pulled elbow emerged as the most common injury in 52% of cases. Among fractures, supracondylar humerus fractures had the highest prevalence. Closed reduction was the predominant intervention, followed by casting. There was no significant association between gender and injury type (P=0.211). However, a statistically significant relationship was identified between age and injury type (P=0.0001).
Conclusion: This study revealed that pulled elbow and supracondylar humerus fractures were the most common injuries, with the closed reduction being the predominant treatment method. While gender did not significantly correlate with injury type, age showed a noteworthy association, indicating an increased risk with advancing age.

Abstract
A thorough review of the available scientific works related to the use of gene therapy to address orthopedic disorders was performed. This review highlights the considerable promise of gene therapy in transforming clinical practice in this domain. Orthopedic conditions, including a range of problems, such as spinal fusion failure, disc degeneration, fractures, segmental bone defects, bone tumors, joint disorders, soft-tissue injuries, genetic disorders, and nerve and muscle disorders, often pose significant challenges for traditional surgical or medical treatments. Consequently, a concerted effort has been made to explore gene therapy as a viable alternative. This innovative approach has made significant progress, although several hurdles must be addressed before widespread clinical application in humans. However, gene therapy has considerable potential as a promising treatment option for orthopedic disorders in the 21st century. As gene transfer techniques continue to advance, the potential applications of gene therapy for orthopedic disorders are expected to expand significantly.

Abstract
The intricate orchestration of cell types and developmental processes in multicellular organisms hinges upon signaling pathways, such as Wnt, which play a pivotal role in embryonic development and adult tissue homeostasis. Over the past four decades, significant efforts have been made to elucidate the complexities of the Wnt signaling pathway and its diverse physiological functions. Wnt signaling has emerged as a crucial regulator in orthopedic contexts, particularly in fracture healing and osteoarthritis. This review delves into the intricate involvement of the Wnt pathway in these orthopedic conditions and explores its impact on bone formation, chondrogenesis, and joint pathologies. Moreover, it examines the therapeutic potential of targeting Wnt signaling in the treatment of osteoporosis, highlighting the promising avenues opened by advancements in understanding rare bone disorders, such as sclerosteosis and van Buchem disease. By elucidating the multifaceted roles of Wnt signaling in orthopedic health and disease, this review offers insights into potential therapeutic strategies to enhance fracture healing, mitigate osteoarthritis progression, and address bone-related disorders.

Abstract
Background: Previous studies have shown a moderate correlation between bone mineral density (BMD) measured by dual-energy x-ray absorptiometry (DEXA) and Hounsfield units (HU) assessed on diagnostic computed tomography (CT) scans in the lumbar spine.
Objectives: In this study, we aimed to evaluate the correlation between DEXA scores and HU values for different bones and several anatomical landmarks.
Methods: In this retrospective study, 214 patients underwent DEXA and diagnostic CT scans of different bones, including the proximal humerus (n=96), distal tibia (n=56), distal femur (n=34), and proximal tibia (n=28). HU values of five anatomic landmarks, including the medulla, anteromedial cortex, anterolateral cortex, posteromedial cortex, and posterolateral cortex, were measured, and their correlation with the lowest T-score of the patients was assessed.
Results: The HU of the center of the medulla was significantly correlated with the lowest T-score in the proximal (r=0.486, P=0.04) and distal tibia (r=0.458, P=0.01). In the proximal humerus, the HU of the anteromedial cortex was significantly correlated with the lowest T-score (r=0.0353, P=0.01). The mean HU of the posterolateral cortex in the proximal humerus was significantly smaller in the osteoporotic patients (P=0.003). The mean HU of the center of the medulla in the proximal tibia was significantly lower in patients with osteoporotic (P=0.036). The mean HU values of the posteromedial cortex and center of the medulla in the distal tibia were significantly larger in patients with normal BMD (P=0.04 both).
Conclusion: A moderately significant correlation is observed between the lowest T-score and specific anatomical landmarks of the different bones.

Abstract
Background: The acromioclavicular joint (ACJ) connects the clavicle and scapula, ensuring shoulder girdle coordination. In subacute injuries, acromioclavicular and coracoclavicular ligaments retain healing potential and often require surgical treatment to repair the tissue. The clavicular hook plate, fixed to the back of the ACJ after reduction, prevents redislocation.
Objectives: This study aims to investigate the suitability of hook plate surgery without ligament reconstruction in patients with subacute ACJ.
Methods: A retrospective cohort study was conducted on 38 patients with subacute ACJ injuries treated with a hook plate without reconstruction. Demographic data, injuries, timing of surgery, and infection history were collected. Eligible patients were contacted for final assessment.
Results: Most patients were men (86.84%), with a mean age of 41 years. Surgery was predominantly on the dominant hand (63.16%). The mean shoulder range of motion (ROM) was 157.89° for forward flexion, 153.95° for abduction, and 50.79° for external rotation. The highest pain was in the first six weeks (70%). Over 80% of the patients had no post-surgery infection, and 97% did not require re-surgery. No significant statistical relationship was found between pain intensity and other variables (P>0.05). Men reported clinically higher pain levels. Younger patients (<45 years) had significantly better ROM (P<0.05).
Conclusion: The present study showed that hook plate fixation was effective for subacute ACJ injuries, with better outcomes in patients ≤45 years old.
