Background Improving the quality of life of scoliosis patients with appropriate preventive measures is critical. This study aimed to investigate the relationships among bone mass, Cobb angle, and complete blood count (CBC) parameters in patients with scoliosis. Material/Methods This joint study was conducted by the pediatric department and orthopedics clinics, which used the medical records of patients aged 10–18 years between 2018 and 2022. Patients were divided into 3 groups according to the Cobb angle. Patient blood count levels from medical records and bone mineral density (BMD) Z scores (g/cm 2 ) were compared among groups. Notably, BMD Z scores were calculated using a (BMD) dataset from local Turkish children after adjusting for height and age. Results A total of 184 individuals (120 females, 64 males) were included in the study. There were statistically significant differences among the groups in platelet-to-lymphocyte ratio (PLR). Significant differences in DXA Z scores among groups were found. There was a significantly strong and positive correlation between DXA Z scores and all CBC parameters in patients with severe scoliosis. Conclusions This study found that CBC parameters can predict BMD in adolescents. Furthermore, the association between vitamin D deficiency and low BMD may contribute to the follow-up of body adaptation in patients with scoliosis receiving conservative treatment.

This study aims to biomechanically and histopathologically investigate the effects of methylene blue (MB) on preventing postoperative adhesion in chickens undergoing fullthickness flexor tendon incision. Materials and methods: This study was performed between June 2017 and June 2018 on Hubbard JA 57 type chickens (age, 6 months; weight, 2.2±0.3 kg). Sixty-four tendons were studied in 32 chickens, including 16 in the control group and 16 in the experimental group. The second and third finger flexor digitorum profundus tendons of the left foot of each chicken were repaired primarily after a full-thickness incision approximately 1 cm proximal to the distal adhesion area. In the control (n=32) and experimental groups (n=32), 0.25 mL of normal saline and 0.25 mL of 1% MB solutions were applied locally to the surgical site, respectively. The operated limb was immobilized using a circular cast. 16 chickens were randomly selected in each group and examined at the fourth week, and the remaining 16 chickens were examined at the sixth week. Thirty-two of these tendons were evaluated using the Tang histopathological adhesion classification system, and the other 32 were evaluated with a biomechanical pull system. Results: Adhesion was found to be less in the experimental group compared to the control group at the end of the fourth and sixth weeks both histopathologically and biomechanically. Furthermore, adhesion was significantly less in the experimental group at the end of the sixth week compared to the fourth week both histopathologically and biomechanically. Conclusion: Histopathological and biomechanical results show that MB, which has anti-inflammatory, antiseptic, antimicrobial and antioxidant effects, reduces adhesion during the healing process after tendon repair. We think that local MB application, particularly in surgeries performed after this type of injury, will be beneficial on early rehabilitation and functional results.

Background Identifying predictive factors for anthropometric changes during puberty in adolescent idiopathic scoliosis (AIS) is critical for prognosis and management. This study aimed to discern these factors in the Turkish AIS population, by analyzing variations against female breast development stages and male testicular volume, benchmarked against national standards. Material/Methods A cross-sectional study was conducted between 2018 and 2022, involving children aged 10 to 18 years from the Orthopedics and Pediatrics Clinics. AIS patients and controls were assessed concerning pubertal status (Tanner stage), chronological age, skeletal maturation (Tanner-Whitehouse), and anthropometric parameters (height, weight, and body mass index). Results AIS patients were compared to controls, stratified by pubertal stages. In girls across all stages, significant differences emerged in bone age, BMI, and weight between AIS and controls ( p <0.01). In boys, AIS patients significantly differed in bone age from controls across all stages ( p <0.001). At stage V, controls demonstrated higher BMI than AIS boys ( p <0.001), while at stage I, AIS boys had significantly higher height and weight compared to controls ( p <0.001). Conclusions AIS patients demonstrate distinctive pubertal growth abnormalities, with males and females presenting divergent patterns. Understanding these variations could inform better management of AIS during the critical pubertal growth period.
