PURPOSE: The breakpoint for a 360° radiotherapy gantry is typically positioned at 180°. This arbitrary setting has not been systematically evaluated for efficiency and may cause redundant gantry rotation and extended setup times. Our study aimed to identify an optimal gantry breakpoint angle for a full-gantry proton therapy system, with the goal of minimizing gantry movement. MATERIALS AND METHODS: We analyzed 70 months of clinically delivered proton therapy plans (9152 plans, 131 883 fractions), categorizing them by treatment site and mapping the fields from a partial-gantry to full-gantry orientation...

We are reporting a case of gastric volvulus in a 52-year-old man in the setting of a paraesophageal hernia initially identified on computerized tomography (CT). CT of the abdomen showed a large paraesophageal hernia with intra-thoracic herniation of the distal stomach and gastroduodenal junction, resulting in mesenteroaxial rotation consistent with acute gastric volvulus. Esophagogastroduodenoscopy (EGD) confirmed the presence of the gastric volvulus, which was initially temporized with endoscopic detorsion...

OBJECTIVE: To investigate the effects of bracing on apical vertebral derotation and explore the factors that influence in-brace derotation effects in adolescent idiopathic scoliosis (AIS) patients. For patients with AIS, vertebral rotation causes cosmetic appearance abnormalities and acts as an indicator for curve progression. However, there have been few studies investigating the precise derotation effects of bracing for apical vertebra. The application of EOS imaging system enables quantitative evaluation of vertebral rotation in the axial plane in a standing position...

INTRODUCTION AND AIM: Scoliometry is not always included in the examination protocol of IS patients. The aim of this report is to examine the degree of correlation of Segmental Rib Index (SRI) to scoliometry, in order for SRI to be used as a surrogate of scoliometric angle of trunk rotation (ATR). MATERIAL AND METHOD: 66 Idiopathic Scoliosis (IS) subjects were studied, with a mean age 12.2 ± 2.9 years, 18 boys and 48 girls: 20 thoracic, 22 thoracolumbar and 24 lumbar curves...

OBJECTIVE: To investigate the effects of physiotherapeutic scoliosis-specific exercises (PSSE) on coronal, horizontal, and sagittal deformities of the spine in adolescent idiopathic scoliosis (AIS) as well as how curve severity, intervention duration, and intervention type could modify these effects. DATA SOURCES: Data sources included the PubMed, Web of Science, Embase, Cochrane Library, and Scopus databases, searched from their inception to September 5, 2023. STUDY SELECTION: Clinical controlled trials reporting the effects of PSSE on the Cobb angle, angle of trunk rotation (ATR), thoracic kyphosis (TK), or lumbar lordosis (LL) in AIS patients aged 10 to 18 years...

PURPOSE: We investigated spatial resolution loss away from isocenter for a prototype deep silicon photon-counting detector (PCD) CT scanner and compare with a clinical energy-integrating detector (EID) CT scanner. MATERIALS AND METHODS: We performed three scans on a wire phantom at four positions (isocenter, 6.7, 11.8, and 17.1 cm off isocenter). The acquisition modes were 120 kV EID CT, 120 kV high-definition (HD) EID CT, and 120 kV PCD CT. HD mode used double the projection view angles per rotation as the "regular" EID scan mode...

STUDY DESIGN: Retrospective case series. OBJECTIVE: To characterize the change in angle of trunk rotation (ATR), axial vertebral rotation (AVR), and body surface rotation (BSR) in patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal fusion (PSF) with en-bloc derotation across multiple postoperative visits. SUMMARY OF BACKGROUND DATA: Previous research has documented ATR, AVR, and BSR correction for AIS patients after surgery...

This scoping review aims (1) to map the literature dealing with neurophysiological and biomechanical aspects of back problems in athletes in order to identify valid risk-factors for their prevention, plus (2) to identify gaps in the existing research and propose suggestions for future studies. A literature search conducted with Scopus, Web of Science, MEDLINE and Cochrane Library was completed by Elsevier, SpringerLink and Google Scholar. The main neurophysiological risk factors identified leading to back problems in athletes are neuromuscular imbalance, increased muscle fatigability, muscle dysfunction and impaired motor control, whilst biomechanical risk factors include maladaptive spinal, spinopelvic and lower limb kinematics, side-to-side imbalances in axial strength and hip rotation range of motion, spinal overloading and deficits in movement pattern...

BACKGROUND: Thoracic rotation mobility is crucial for athletes in rotational sports such as baseball, golf, and swimming to maintain the proper biomechanics associated with the sport. Accurate differentiation between normal mobility and active and passive physiological deficits in the thoracic region is critical for identifying the need for intervention to the thorax. PURPOSE: To establish the reliability and discriminant validity of visual estimation of thorax rotation range of motion across clinicians of differing experience levels in determining normal mobility and active or passive physiological deficits when utilizing the quadruped lumbar-locked position...

BACKGROUND/PURPOSE: Interventions including posterior glenohumeral mobilizations (PGM), sleeper stretches, and thoracic manipulation are commonly used to address posterior shoulder tightness. The purpose of this study was to assess the effects of adding thoracic manipulation to PGM and sleeper stretches on passive range of motion (PROM), joint mobility, and infraspinatus electromyographic (EMG) activity in shoulders with decreased internal rotation (IR) PROM. DESIGN: Randomized Sequential Intervention Laboratory Study...

BACKGROUND: Sacropelvic fractures with multidirectional instability require complex reduction and stabilisation techniques. Triangular osteosynthesis reconstruction is an established technique but hardware failure rates remain high and screw trajectories unfamiliar to spine surgeons. Our technique allows de-rotation of the pelvis, fracture reduction in both vertical and transverse planes, immediate weight bearing and is more reproducible for complex spine surgeons. OBJECTIVE: To describe our case series of dual triangular osteosynthesis reduction and stabilisation for complex sacropelvic fractures...

BACKGROUND: Increased kyphosis is a common condition among older people that may, directly or indirectly, be a risk factor for poor balance and gait. Spinomed and Biofeedback Posture Trainer (BPT) orthoses is an effective treatment approach for hyperkyphosis. This study aimed to compare the immediate effects of the Spinomed and BPT orthoses on balance and gait in the older population. METHODS: A total of 52 volunteer older people with hyperkyphosis (kyphosis angle>40°) participated in this study and were randomly allocated into two groups, to either the Spinomed orthosis (n = 26, mean age = 65...

OBJECTIVE: S2 alar-iliac (S2AI) screw had been widely used in the pelvic fusion for degenerative lumbar scoliosis (DLS) patients. However, whether S2AI screw trajectory was influenced by sagittal profile in DLS patients had not been comprehensively investigated. The objective of this study was to evaluate the associations between the optimal S2 alar-iliac (S2AI) screw trajectory and sagittal spinopelvic parameters in DLS patients. METHODS: Computed tomography (CT) scans of pelvis were performed in 47 DLS patients for three-dimensional reconstruction of S2AI screw trajectory from September 2019 to November 2021...

BACKGROUND: In conventional practice, the left double lumen tube (DLT) is rotated 90° counterclockwise when the endobronchial cuff passes glottis. Success rate upon the first attempt is < 80%, likely owing to varying morphology of the bronchial bifurcation. METHODS: We conducted a randomized controlled trial to compare 90° counterclockwise rotation versus individualized degree of rotation in adult patients undergoing elective thoracic surgery using left DLT...

BACKGROUND: Pneumothorax following shoulder arthroscopy, although rare, is documented in over 30 PubMed case reports as occurring during or within 10 hours post-procedure. CASE PRESENTATION: A fit septuagenarian underwent a two-hour arthroscopic rotator cuff repair with IV anaesthesia and laryngeal mask airway, without a nerve block. With one hour remaining of the operation, the patient had desaturation and hypotension. Lung sliding was absent on ultrasound and x-ray confirmed left-sided tension pneumothorax...

Skeletal ciliopathies constitute a subgroup of ciliopathies characterized by various skeletal anomalies arising from mutations in genes impacting cilia, ciliogenesis, intraflagellar transport process, or various signaling pathways. Short-rib thoracic dysplasias, previously known as Jeune asphyxiating thoracic dysplasia (ATD), stand out as the most prevalent and prototypical form of skeletal ciliopathies, often associated with semilethality. Recently, pathogenic variants in GRK2, a subfamily of mammalian G protein-coupled receptor kinases, have been identified as one of the underlying causes of Jeune ATD...

OBJECTIVE: To investigate the associations of glenohumeral internal (IR) and external rotation (ER), horizontal adduction (HA), and thoracic spine rotation ranges of motion (ROM), isometric muscle strength of the shoulder rotators, and trunk muscle endurance with the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST), the Upper Quarter Y Balance Test (YBT-UQ), and the Upper Limb Rotation Test (ULRT) in overhead athletes. DESIGN: Cross-sectional study...

BACKGROUND: Double lumen endobronchial tubes (DLTs) are frequently used to employ single lung ventilation strategies during thoracic surgical procedures. Placement of these tubes can be challenging even for experienced clinicians. We hypothesized that airway anatomy, particularly of the glottis and proximal trachea, significantly impacts the ease or difficulty in placement of these tubes. METHODS: Images from 24 randomly selected Positron Emission Tomography - Computed Tomography (PET-CT) scans were evaluated for several anatomic aspects of the upper airway, including size and angulation of the glottis and proximal tracheal using calibrated CT measurements and an online digital protractor...
