Prominent in the L-shaped three-dimensional structure of tRNAs is the "elbow" where their two orthogonal helical stacks meet. It has a conserved structure arising from the interaction of the terminal loops of the D- and T-stem-loops, and presents to solution a flat face of a tertiary base pair between the D- and T-loops. In addition to the ribosome, which interacts with the elbow in all three o...

BACKGROUND Tennis elbow (TE) is a common musculotendinous degenerative disorder of the extensor origin at the lateral humeral epicondyle. Different modes of treatment are used for management of tennis elbow. OBJECTIVES This study investigated the effect of the taping technique (TT) on pain, grip strength and wrist extension force in treatment of tennis elbow. PATIENTS AND METHODS Thirty pat...

Sudden and intermittent locking of the elbow joint is a com- mon complaint among patients who commonly demonstrate degenerative changes in the elbow. Common causes of elbow locking include acute trauma, osteochondritis dessicans, synovial chondromatosis, and osteoarthritis. Two cases involving patients with symptoms of elbow locking secondary to reasons other than loose bodies within the joint ...

BACKGROUND In patients who have an injury of the cervical spinal cord, the brachioradialis tendon may be transferred to the extensor carpi radialis brevis tendon to restore voluntary wrist extension. We hypothesized that the active range of motion of the wrist depends on the position of the elbow after this transfer because the brachioradialis changes length substantially during elbow flexion, ...

PURPOSE Previous in vivo and in vitro studies of forearm supination-pronation suggest that distal radioulnar joint kinematics may be affected by elbow flexion. The primary hypotheses tested by this study were that, in vivo, ulnar variance changes with elbow flexion and forearm rotation, and the arc of forearm rotation changes in relationship to elbow flexion. METHODS Changes in radioulnar kin...

Significant excursion of the ulnar nerve is required for unimpeded upper extremity motion. This study evaluated the excursion necessary to accommodate common motions of daily living and associated strain on the ulnar nerve. The 2 most common sites of nerve entrapment, the cubital tunnel and the entrance of Guyon's canal, were studied. Five fresh-frozen, thawed transthoracic cadaver specimens (1...

BACKGROUND This study was designed to assess the relationship between work-related combined physical and psychosocial factors and elbow disorders (lateral epicondylitis and non-specific disorders without lateral epicondylitis) in the working population. METHODS A total of 3,710 workers (58% men) in a French region in 2002-2005 participated in physical examinations by occupational health physi...

Pediatric post-traumatic elbow contracture can occur as result of the various injuries of area of the elbow joint. The aim of the study was to investigate the effect of the physical therapy and rehabilitation on the range of the motion of the elbow joint in the post-traumatic elbow contractures in the childhood. We analyzed in this research 54 children (average age 9,4+/-3,15 years) that were t...

BACKGROUND Elbow surgery is shared by several subspecialties. We were curious about the most common elbow surgeries and their corresponding diagnoses in the United States. METHODS We used the National Hospital Discharge Survey (NHDS) and the National Survey of Ambulatory Surgery (NSAS) data gathered in 2006-databases that together provide an estimate of all inpatient and ambulatory surgical c...

BACKGROUND There have been no reports on the long-term outcome of radial neck Mason type IIIb fractures in adults. METHODS 3 women and 2 men, aged 46 (22-69) years when they sustained a radial neck Mason type IIIb fracture, were evaluated after an average of 18 (16-21) years. All had been treated with radial head excision. RESULTS 3 individuals had no subjective elbow complaints while 2 rep...
