Shoulder kinesthesia after anterior glenohumeral joint dislocation.
The purpose of this study was to examine kinesthesia in normal (uninjured) shoulders and in shoulders with a history of glenohumeral joint dislocations. Both shoulders of 10 healthy subjects and 8 subjects with a history of unilateral anterior dislocation were tested for accuracy of angular reproduction, threshold to sensation of movement, and end-range reproduction using a motor-driven shoulde...
متن کاملJoint stability after total shoulder arthroplasty in a cadaver model.
A cadaver model was used to test the hypothesis that glenohumeral joint stability is independent of articular surface conformity after total shoulder arthroplasty. For the purposes of this study joint stability was defined as the minimum force required for joint dislocation. After arthroplasty components were implanted into fresh-frozen glenohumeral joints, specimens were mounted on a load fram...
متن کاملTechnique and Application for Quantifying Dynamic Shoulder Joint Kinematics and Glenohumeral Joint Contact Patterns
The shoulder (glenohumeral) joint has the greatest range of motion of all human joints; as a result, it is particularly vulnerable to dislocation and injury. The ability to accurately measure dynamic in-vivo joint kinematics in 6-Degrees-of-Freedom (6-DOF) (translations and rotations) and subsequently quantify articular cartilage contact patterns of that joint has been and remains a difficult b...
متن کاملTranexamic Acid in Total Joint Arthroplasty: Efficacy and Safety
Despite improvements in surgical and anesthetic techniques, total joint arthroplasty (TJA) is still associated with substantial blood loss and postoperative anemia (1). A considerable portion of patients with postoperative anemia require blood transfusion, which has been shown to negatively affect the outcome of TJA and predisposes patients to development of surgical site infection and peripr...
متن کاملHumeral-sided Radiographic Changes Following Reverse Total Shoulder Arthroplasty
Background: We sought to characterize humeral-sided radiographic changes at a minimum of 2 years after reverseshoulder arthroplasty (RSA) to determine their association with specific implantation techniques.Methods: The immediate and most recent postoperative anteroposterior radiographs of 120 shoulders with primary RSAand a minimum of 2-years of radiographic follow-up were an...
