Distal humerus fractures, which are challenging injuries seen in geriatric patients, are often repaired using open reduction and internal fixation or total elbow arthroplasty. This updated meta-analysis, which includes more recent open reduction and internal fixation techniques, examined outcomes following distal humerus fractures repaired using open reduction and internal fixation vs total elbow arthroplasty. Although distal humerus fractures treated with total elbow arthroplasty achieved statistically higher functional scores relative to those treated with open reduction and internal fixation, this difference was not clinically significant.

The two-segment model of the human arm is considered; the shoulder and elbow joint torques (JTs) are simulated, providing a slow, steady rotation of the force vector at any end-point of the horizontal working space. The sinusoidal waves describe the JTs, their periods coincide with that of the rotation, and phases are defined by the slopes of the correspondent lines from the joint axes to the end-point. Analysis of the JTs includes an application of the same discrete changes in one joint angle under fixation of the other one and vice versa; the JT pairs are compared for the "shoulder" and "elbow" end-point traces that pass under fixation of the elbow and shoulder angles, respectively.
