Adjunct fixation with a Kirschner wire or a plate for lateral unicondylar humeral fracture stabilization.

Objective: To compare the biomechanical properties of using an interfragmentary 1.6 mm Kirschner wire or a 2.7 mm reconstruction plate as adjunctive epicondylar stabilization in simulated comminuted lateral unicondylar humeral fractures stabilized with a transcondylar 4.

Mechanics of Supplemental Drop Wire and Half-Pin Fixation Elements in Single Ring Circular External Fixator Constructs.

Objective: Evaluate the effects of supplemental fixation elements on the mechanical properties of a single ring circular fixator construct.

Study Design: In vitro mechanical testing.

Sample Population: Five construct configurations (six replicates of each configuration) were used to stabilize a 1.

Fluoroscopic motion study confirming the stability of a medial pivot design total knee arthroplasty.

Background: The ideal total knee arthroplasty should provide maximum range of motion and functional stability for all desired daily activities. The SAIPH™ (MatOrtho; UK) knee has a medial pivot knee kinematic pattern designed to achieve medial stability and an asymmetric posterior translation of the lateral femoral condyle during knee flexion and in this way attempts to mimic the natural knee motion. This study aims to analyze knee kinematics of the SAIPH™ total knee arthroplasty (TKA) by videofluoroscopy during four different weightbearing activities.
