Methods: In this experimental animal study, a total of 63 male Wistar albino rats (200-250 g) were randomly assigned to 3 groups: TBI with tibia fracture (TBI+Fx, n=21), tibia fracture only (Fx only, n=21), and a control group (n=21). Traumatic brain injury was induced in the motor cortex using a controlled impact device, followed by the tibia fracture. The severity of TBI was assessed using rotarod tests. Blood samples were collected on days 1, 7, and 21 post-fracture, while brain and tibia samples were taken on day 21 following decapitation. Levels of antidiuretic hormone (ADH) and angiotensin 1-7 (Ang 1-7) were quantified using Enzyme-linked immunosorbent assays (ELISA). Fracture healing was assessed through micro-CT and histopathological analysis. Aortic segments were evaluated for contractile response and relaxation in isolated organ baths. Results: Micro-CT analysis revealed significantly greater bone volume (BV) (P=.02) and trabecular number (P=.038) in the TBI+Fx group. Histopathological healing scores were also significantly higher in the TBI+Fx group compared to the Fx only group (P=.019). Potassium chloride (KCl) induced contractile responses were greater in the Fx only group than in the TBI+Fx group (P < .05). Acetylcholine (ACh) induced relaxation was diminished in both Fx and TBI+Fx groups compared to controls (P < .01), whereas sodium nitroprusside (SNP)-induced relaxation was significantly greater in the TBI+Fx group than in the Fx only and control groups (P < .05). On day 21, arginine vasopressin (AVP) levels were significantly higher in the Fx only group compared to the TBI+Fx group (P=.034), with no significant differences observed on days 1 and 7. Plasma Ang 1-7 levels were significantly elevated in the Fx only group on day 21 compared to the TBI+Fx group (P < .05). Conclusion: Traumatic brain injury was associated with accelerated fracture healing, as evidenced by increased BV, trabecular thickness, and histopathological healing scores. Additionally, TBI appeared to modulate vascular function, possibly via mechanisms involving nitric oxide and calcium signaling. These findings suggest that neuroendocrine changes following TBI may enhance fracture healing, offering potential clinical insights for managing polytrauma patients.

Traditional techniques have limitations in addressing multidirectional instability and minimizing implant-related complications. The aim of this study was to evaluate the clinical and radiological outcomes of a combined coracoclavicular (CC) ligament and transacromial capsule reconstruction technique in patients with chronic AC joint instability. Methods: A retrospective study was performed on 40 patients who underwent AC joint reconstruction at a single center from 2019 to 2023. Radiological outcomes (clavicle-coracoid distance) were evaluated preoperatively, immediately postoperatively, and at the last follow-up (6 months). Functional results were assessed using the Constant, American Shoulder and Elbow Surgeons score (ASES), and Disabilities of the Arm, Shoulder, and Hand (DASH) score. Data were analyzed using SPSS v28.0. T-tests and repeated measures of Analysis of Variance (ANOVA) were employed to compare outcomes, with significance set at P < .05. Results: The preoperative mean CC distance was 20.3 ± 3.4 mm. Early postoperative measurements showed a significant reduction in CC distance, with a mean of 9.5 ± 1.5 mm in the capsule reconstruction group compared to 10.5 ± 1.6 mm in the non-reconstruction group (P=.053). At the 6-month follow-up, the late postoperative CC distance was maintained at 10.1 ± 1.6 mm in the reconstruction group, while it increased to 14.4 ± 2.0 mm in the non-reconstruction group (P < .001). The mean ASES score was 87.1 ± 8.1. The mean Constant score was 86.2 ± 7.6. Pain levels, evaluated using the Visual Analog Scale (VAS), decreased from a mean of 5.8 ± 1.2 preoperatively to 2.1 ± 1.0 postoperatively, indicating significant pain relief and improved functionality. No hardware failure or infection was noted. About 12.5% of patients experienced short-term anterior knee pain. Conclusion: The results of this study demonstrate that combined CC ligament and transacromial capsule reconstruction improves radiographic outcomes by maintaining the clavicle-coracoid distance and enhances functional scores (ASES and Constant) in patients with chronic AC joint instability. Addressing both vertical and horizontal instability appears to contribute to better short-term clinical recovery. Further studies with larger sample sizes and longer follow-up are needed to confirm these findings.

Methods: A total of 74 patients who underwent TKA surgery by a single surgeon between 2018 and 2021 were included in the study. The patients were then divided into 2 groups according to their femoral component design: group SR (38 patients) and group MR (36 patients). Except for gender and follow-up duration (P < .05), no significant difference was observed in age, American Society of Anesthesiologists scores, and BMI (P > .05). Knee range of motion, visual analogue scale (VAS), and combined KSS (Knee Society Score) were evaluated at the preoperative and final controls of the patients. In addition, frequency of anterior knee pain (AKP), AKP scale, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Hospital for Special Surgery (HSS) score, and the Forgotten Joint Score-12 (FJS12) were evaluated at the final follow-up. Results: There was no difference between the 2 groups in terms of postoperative range of motion (ROM), VAS, combined KSS, and HSS (P > .05). The frequency of AKP in patients with SR was found to be statistically lower than those with MR (P=.021; P < .05).

This study aimed to compare the impact of a polyether ether ketone (PEEK) forked eyelet tenodesis screw with the traditional PEEK closed eyelet whipstitching technique. The focus was on evaluating the occurrence of Popeye deformity, which is an objective predictor of a successful arthroscopic suprapectoral long head of biceps tenodesis. Methods: A retrospective analysis was conducted on patients who underwent arthroscopic rotator cuff repair and biceps tenodesis performed by a single surgeon between January 2010 and 2020 at a single center. The follow-up period was at least 1 year. Exclusion criteria included previous shoulder surgery and osteoarthritis. Patients were divided into 2 groups based on the type of tenodesis anchor used: forked eyelet tenodesis screw versus closed eyelet tenodesis screw. The occurrence of Popeye deformity was compared between the 2 groups. Results: A total of 82 patients who underwent arthroscopic rotator cuff repair and biceps tenodesis were evaluated, with a mean follow-up of 24.5 ± 4 months. The patients operated on using forked eyelet tenodesis screw were labeled as Group I (n=72) and those with traditional PEEK closed eyelet screw as Group II (n=10).

Methods: This retrospective study analyzed 2516 patients (1548 females and 968 males) with a mean age of 51.83 ± 15.6 years with chronic low back pain who underwent lumbosacral magnetic resonance imaging and computed tomography scans at a single center between January 2018 and January 2021. Pfirrmann grading was used to assess L4-L5 intervertebral disc degeneration, and Castellvi classification determined the anatomical type of LSTV. Correlation analysis was performed to evaluate the association between LSTV presence and disc degeneration. Additionally, a proportional-odds ordinal logistic regression model was used to examine the relationship between Pfirrmann grade and patient-specific factors (age, gender, and LSTV presence). Results: According to Pfirrmann classification, 113 patients were grade I, 402 were grade II, 877 were grade III, 861 were grade IV, and 263 were grade V. A total of 771 patients (30.6%) did not have LSTV, while the remaining 1745 patients (69.4%) had LSTV. A statistically significant association was found between LSTV presence and Pfirrmann grade (P < .001, r=.200). Patients with LSTV had 0.75 times higher probability (95% CI: 0.58-0.90, P < .001) of exhibiting a higher Pfirrmann grade compared to those without LSTV. However, no significant correlation was observed between LSTV subtypes classified by Castellvi and Pfirrmann grade (P=.379). Additionally, age was significantly correlated with Pfirrmann classification, LSTV presence, and Castellvi classification (P < .001). Female patients had 1.34 times higher likelihood (95% CI: 1.19-1.49, P < .001) of exhibiting a higher Pfirrmann grade compared to male patients. Conclusions: This study highlights the significant association between LSTV and advanced disc degeneration, establishing LSTV as a potential risk factor for progressive spinal changes.

The rats were divided into 4 groups (n = 6 per group). Group A was the sham group, and the 3 treatment groups were as follows: group B (primary repair), group C (primary repair + ACS), and group D (primary repair + HA). A standardized procedure was used to create an acute tear-and-repair model of the RC in each treatment group. The rats in group B received no injections. Group C received ACS 24, 48, and 72 h after surgery. Patients in group D received a single dose of HA at the operative site. After a 4-week follow-up period, the rats were subjected to an exercise protocol using a computer-monitored motorized treadmill. For each treadmill run, shocks were recorded as one penalty point using a computer (one point per shock). Subsequently, the rats were sacrificed and bone-tendon healing in each group was assessed histopathologically. Results: Group A had the lowest penalty points in the final run and the highest penalty points. The best performance among the surgical groups was observed in group D. Groups C and D received fewer penalty points than group B.
