Rupture of the Long Head of Biceps tendon (LHB) results in varying elbow flexion strength deficit (mean deficit: 8%, S.D. 12% of mean) (Mariani et al. 1988). This variability in strength is interesting because it is previously unexplained. Observations of musculoskeletal parameters also exhibit variability (Murray et al. 2000). We hypothesize that the variation in elbow flexion strength in heal...

Elbow medial collateral ligament sprain occurs when the elbow is subjected to a valgus force exceeding the tensile properties of the medial collateral ligament (MCL). This is an injury seen more often in throwing athletes. Understanding the differential diagnosis of medial elbow pain is paramount to diagnose MCL injury as well as addressing other medial elbow pathology. A natural evolution rega...

The purpose of the present study was to review the long-term results of surgical arthrolysis of the elbow. We reviewed 16 patients, with a mean follow-up of 47 months. Elbow motion before, during and after operation was measured. DASH score, pain and patient satisfaction were assessed. We found a significant (p < 0.05) improvement in elbow motion postoperatively. The total arc of motion improve...

Background The location of the ulnar styloid process can be confusing because the radius and the hand rotate around the ulna. The purpose of this study was to identify the absolute location of the ulnar styloid process, which is independent of forearm pronation or supination, to use it as a reference for neutral forearm rotation on lateral radiographs of the wrist. Methods Computed tomography...

A patient with a 2-year history of pain in the left arm, and decreased strengths unrelieved by non-steroidal anti-inflammatory therapy, was being referred for repeating radiography. The radiologic examinations have demonstrated a unique pattern of non-contiguous osteolysis in the left elbow, proximal and distal radius, ulna, wrist, carpal bones, proximal and distal metacarpals and phalanges. Mu...

The theory that differential growth of opposed chondrogenic centres is important in early joint formation has been tested experimentally by removing structures in relation to the chick elbow joint. The humerus and its cap of differentiating joint cells were found to develop independently of structures distal to them. Removal of the presumptive joint region at early stages resulted in fusion of ...

BACKGROUND Radial neck fractures in children are rare, representing 5% of all elbow pediatric fractures. Most are minimally displaced or nondisplaced. Severely displaced or angulated radial neck fractures often have poor outcomes, even after open reduction, and case series reported in literature are limited. The aim of the study is to analyze the outcomes of patients with a completely displaced...

Davenport, Taylor, and Nelson (1924) have reported several instances of familial radio-ulnar synostoses with variable degrees of reduction in pronation and supination. Their cases fall into three general types: (1) radius without a head; (2) radial head displaced backwards; and (3) radial head more or less normal but radial shaft strongly curved. Cockshott and Omololu (1958) reported a father a...

Forearm rotation occurs around an axis connecting the center of the radial head and the fovea of the distal ulna. The purpose of the present study was to demonstrate the usefulness of the difference between forearm and proximal radial axis in the treatment of malunited forearm fractures. We reviewed the results of eight corrective osteotomies for malunited fractures of the forearm without dislo...

Retrospective cohort design. The minimal clinically important difference (MCID) for the quick Disabilities of the Arm, Shoulder and Hand (QDASH) has been established using a pool of multiple conditions, and only exclusively for the shoulder. Understanding diagnoses-specific threshold change values can enhance the clinical decision-making process. Before and after QDASH scores for 406 participan...
