A kinematic study was performed to examine the influence of elbow position on the range of supination and pronation of the forearm. The ranges of supination and pronation were measured in 50 volunteers (25 men and 25 women) using a custom-designed jig which constrained unwanted and confounding movements of the limb. Measurements were taken with the elbow in full extension, 45 degrees flexion, 9...

Background For decades, tuberculosis (TB) has posed a great threat to people worldwide. Bone and joint TB is one of the most common types of extrapulmonary TB, with elbow TB comprising a small proportion of these cases. The treatment for elbow stiffness associated with TB has been rarely reported. Patients and methods We retrospectively analyzed six patients (four females and two males) with ...

PURPOSE We investigated the best position for shoulder retractor strengthening exercise to maximize middle trapezius activity and minimize rhomboid major activity. Although both trapezius and rhomboids are scapular retractors, rhomboids also act as downward rotators of the scapula, which can worsen subacromial impingement. METHODS Twelve healthy participants (age 30 [SD 6] y) with no history ...

BACKGROUND The purpose of our study was to evaluate the objective and subjective outcomes, as well as the radiographic results after elbow hemiarthroplasty (HA) for comminuted distal humerus fractures in elderly patients. METHODS Ten female patients with a mean age of 75.2 years were treated with elbow HA either for osteoporotic, comminuted distal humerus fractures (n = 8) or for early failed...

Hypothesis: Pain is the result of fraying of Sharpey's fibers (muscle attachment to periosteum). Treatment: Heavy progressive resistance exercises to wrist en tensors. 10 repetitive maximum (RM) with elbow at 90° and 10 RM with elbow at 180°. Do twice daily. Rationale: Exercise will create a dense collagenous scar (pain-free) at the attachment. One might conclude that similar consequences would...

we present a 23-year-old man with distal humerus osteoid osteoma referring to our hospital with pain and progressive stiffness. the patient has been suffering from the disease for two years without a certain diagnosis. the radiographies of elbow did not reveal the pathology but further ct scan and mri studies demonstrated the tumor. the en block resection of the tumor resolved the pain immediat...

force convection heat transfer of turbulent nano fluid flow in 90 and 60 degree elbow is simulated by using fluent. single phase model has been implemented to study such a flow field and standard

Eighteen co-ordination postures with shoulder flexion angles (0°, 45° and 90°) and elbow flexion angles (0°, 45° and 90°) in standing and sitting positions were evaluated to identify the effects of co-ordination postures on maximum grip strength and muscle activities of the upper limb in this study. Thirty-nine subjects were recruited and their maximum grip strengths were measured. According to...
