Purpose: Head constitutes 6% of our body weight and significantly influences human body motor system mechanics. From physiological point of view, it should be located at extension of body middle line. Its location being modified results in many consequences in motor system. Our research was aimed at assessing the influence of head position on human body balance stabilographic variables.
Methods: The research was made on a group of 62 patients: 45 women and 17 men, aged from 40 to 60 yrs, 46 yrs on average. Head position in sagittal and frontal plane was assessed with photogrammetric method. Chosen stability parameters were estimated with dynamometric platform PEL 38 and computer software TWIN 99.
Results: The results confirmed correlations between existing stabilographic values and head position in frontal plane only. Head position, when changed in this plane, increased the amplitude ( p = 0.001) and average speed of body gravity center trembilng ( p = 0.002). There were no significant relations found in sagittal plane ( p > 0.05).
Conclusions: Our results show that the head position influences stabilographic variables. Its change in frontal plane decreases body posture stability to the largest extent.

Purpose: The promotion of task-shifting and task-sharing to facilitate work style reform for physicians has enabled radiological technologists (RTs) to perform primary matching in image-guided radiotherapy. The purpose in this study is to evaluate the position matching accuracy of RTs and radiation oncologist (ROs).
Methods: Position matching was performed by four RTs and two ROs (RO-A and B).

Introduction And Importance: Monteggia lesions combine a fracture of the ulna with dislocation of the radial head. Monteggia-like variants add a radial head fracture. We report a unique Monteggia-like injury with a bifocal radial fracture and subcutaneous enucleation of the radial neck, which does not fit existing classifications.

This study evaluates the clinical presentation, surgical management, and outcomes of silent sinus syndrome (SSS), with emphasis on the efficacy of simultaneous sinus and orbital surgery. A retrospective review was performed of 35 patients diagnosed with SSS at a tertiary care center between January 2004 and April 2024. All patients had radiographic evidence of maxillary sinus atelectasis and orbital floor resorption.

Glenohumeral instability is a common injury affecting contact and collision athletes. Male sex, younger age at time of first dislocation, and contact sports participation are risk factors for recurrent instability. MRI is the gold standard to evaluate soft tissue structures, while CT is beneficial in quantifying glenoid bone loss and identifying on-track and off-track Hill-Sachs lesions.
