BACKGROUND Physiologic dorsal apex angulation of the proximal ulna is present in 96% of the population. We hypothesize that a correlation exists between the physiologic dorsal ulnar angulation and elbow range of motion (ROM). METHODS Fifty healthy adults underwent bilateral lateral elbow radiographs in neutral forearm rotation in the following positions:(More)
Proximal ulna fractures can be difficult to manage because of the elbow's complex anatomy. Advances in understanding elbow anatomy and biomechanics, however, have led to new insights. Careful preoperative evaluation is critical because failure to restore normal anatomy of the proximal ulna could have a detrimental effect on postoperative elbow function.(More)
OBJECTIVE Locking plates have become ubiquitous in modern fracture surgery. Recently, manufacturers have developed locking plates with polyaxial screw capabilities in order to optimise screw placement. It has already been demonstrated that inserting uniaxial locking screws off axis results in weaker loads to failure. Our hypothesis was that even implants(More)
BACKGROUND To use elbow range of motion routinely as a diagnostic index, it is important to explain the normal variability among the population. Consequently, this study assessed the possible associations between age, sex, laterality, body mass index, joint laxity, level of physical activities, upper limb dimensions, and the elbow range of motion in(More)
HYPOTHESIS We hypothesized that the radiocapitellar ratio (RCR) is a valid and reproducible method to assess radial head translation in healthy individuals and that the normal RCR of healthy individuals is 0%. MATERIALS AND METHODS Lateral radiographs of the elbow were examined in 40 healthy patients. The measurement method of the RCR was the displacement(More)
BACKGROUND Recurrent glenohumeral anterior instability (RGAI) frequently induces combined glenoid and Hill-Sachs bone lesions and is a risk factor for soft tissue repair failure. This cohort study describes a simple preoperative quantification method for bone loss, the Clock method, the first that combines glenoid and humeral lesions. METHODS Computed(More)
OBJECTIVES Understanding the anatomy of proximal ulna is important when treating complex injuries, since nonanatomic reconstruction may lead to malunion, arthrosis, and instability. The proximal ulna has a sagittal bow, termed the proximal ulna dorsal angulation (PUDA). The purpose of this study was to evaluate the magnitude of angular malalignment at the(More)
BACKGROUND Radial head alignment is the key to determine elbow reduction after treatment of subluxations or Monteggia fractures. The radiocapitellar ratio (RCR) quantifies the degree of subluxation, by evaluating radial head alignment with the capitellum of the humerus; this ratio is reproducible when measured on true lateral radiographs of nonsubluxated(More)
