PURPOSE: Muscular strength is suggested to be dependent upon muscle characteristics. Yet, sex-specific relationships of muscle characteristics to strength in the resistance-trained require investigation. Therefore, the purpose was to evaluate sex differences in muscle characteristics and isometric strength in the elbow extensors, as well as their respective associations. METHODS: Resistance-trained men (n = 15, mean ± SD 22 ± 4 years, 87.5 ± 12...

BACKGROUND: Muscle degeneration as a consequence of rotator cuff tears is mainly assessed by magnetic resonance imaging. Contrast-enhanced ultrasound (CEUS) is a new functional imaging method to assess microvascular perfusion as a fundamental parameter of muscle tissue vitality. In this cross-sectional study, the authors evaluated supraspinatus muscle perfusion after cuff repair and analyzed its association with functional shoulder outcome and the grade of echogenicity in B-mode ultrasound indicating fatty infiltration...

Elbow dislocations are frequent and present with a broad spectrum of subsequent ligamentous and soft tissue injuries. Beside clinical examination, fluoroscopy, ultrasound and magnetic resonance imaging (MRI) can specify the extent of the injuries and provide a foundation for decision-making between conservative and operative treatment. This article highlights the basic underlying biomechanics and anatomy, discusses the trauma mechanisms and presents clinical and imaging diagnostic procedures. Treatment algorithms for conservative and surgical treatment are presented in detail...

The risk of peripheral intravenous catheter failure varies according to the insertion site. This study examined catheter shape just after removal to evaluate the causes of catheter failure according to site. This study was a secondary analysis of previous study data. Our observational study was conducted during a 6-month period at The University of Tokyo Hospital. Participants were hospitalized adults who received infusion therapy via a short peripheral catheter. We acquired ultrasound images of blood vessels and surrounding tissues at the catheter insertion site before catheter removal and clinical images of the removed catheters...

Achilles tendon mechanics influence plantar flexion force steadiness (FS) and balance. In the upper limb, elbow flexor FS is greater in supinated and neutral forearm orientations compared to pronated, with contributions of tendon mechanics remaining unknown in position-dependent FS. This study investigated whether distal biceps brachii (BB) tendon mechanics across supinated, neutral and pronated forearm orientations influence position-dependent FS of the elbow flexors. Eleven males (23 ± 3 years) performed submaximal isometric elbow flexion tasks at low (5, 10% maximal voluntary contraction (MVC)) and high (25, 50, 75% MVC) force levels in supinated, neutral and pronated forearm orientations...

BACKGROUND: Although the pronator teres muscle, a major dynamic stabilizer of elbow valgus stress during throwing, frequently presents stiffness, its relationship with elbow injuries in youth baseball players is unknown. This study investigated the relationship between the elasticity of the pronator teres muscle and elbow injuries in youth baseball players. METHODS: The strain ratio (SR) of 15 individuals with osteochondritis dissecans of the humeral capitellum (OCD group), 67 individuals with medial epicondylar fragmentation (medial injury group), and 115 healthy individuals (control group) was measured as the index of the elasticity of the pronator teres muscle using ultrasound strain elastography...

This case describes a 16-year-old boy who suffered a severe traumatic brain injury. The patient gradually recovered but developed debilitating spasticity mainly in left triceps muscle, abnormal positioning of shoulder girdle complex, and shoulder pain. Phenol (6%) was injected to axillary and radial nerves under guidance of electrical stimulation and ultrasound imaging at 10 weeks after initial injury. After injection, triceps spasticity and shoulder pain was immediately reduced and abnormal positions of shoulder girdle complex and elbow joint gradually returned to functional limits over 2 weeks...

INTRODUCTION: Chronic lateral epicondylosis (CLE) of the elbow is a prevalent condition among middle-aged people with no consensus on optimal care management but for which surgery is generally accepted as a second intention treatment. Among conservative treatment options, ultrasound (US)-guided fenestration has shown encouraging results that should be explored before surgery is considered. The primary objective of this study is to compare the efficacy of US-guided fenestration with open-release surgery in patients with failure to improve following a minimum 6 months of conservative treatment...
