Hinged external fixation of the elbow: optimal axis alignment to minimize motion resistance.
OBJECTIVE To establish an optimal single hinge axis position for application of hinged external fixation to the elbow joint. DESIGN Cadaveric biomechanical investigation. SETTING A customized motion transducer applied passive elbow motion to six cadaveric upper extremities. The instant rotation axis of the humero-ulnar articulation was determined from three-dimensional kinematic data acquir...
متن کاملHinged external fixation of the knee: intrinsic factors influencing passive joint motion.
OBJECTIVE To measure changes in knee kinematics after the application of articulated external fixators along a previously described knee flexion/extension axis and 16 specific "off-axis" fixator hinge configurations. DESIGN Cadaver, biomechanical study. SETTING Biomechanics laboratory. PARTICIPANTS Nine fresh cadaver knee specimens. INTERVENTION Each specimen was mounted on a custom-bui...
متن کاملAdditional external hinged fixator after open repositioning and internal fixation of acute elbow instability in non-compliant patients
This is a retrospective analysis of the clinical and radiological outcome in 11 patients with complex acute posttraumatic elbow instability after dislocation. These patients had also been treated with a hinged external fixator after open reduction, capsular and ligamentous reconstruction and internal fixation, because of an expected diminished compliance, to avoid a secondary dislocation of the...
متن کاملThe use of hinged external fixation to provide additional stabilization for fractures of the distal humerus.
OBJECTIVE To assess improvements in fixation stability when a hinged unilateral external fixator is used to supplement compromised internal fixation for distal humerus fractures. METHODS Removing a 1-cm section of the distal humerus in cadaveric whole-arm specimens created a comminuted distal humerus fracture model (AO type 13-A3). Fixation was then performed using different constructs repres...
متن کاملCORR Insights ®: Good functional recovery of complex elbow dislocations treated with hinged external fixation: a multicenter prospective study.
BACKGROUND After a complex dislocation, some elbows remain unstable after closed reduction or fracture treatment. Function after treatment with a hinged external fixator theoretically allows collateral ligaments to heal without surgical reconstruction. However, there is a lack of prospective studies that assess functional outcome, pain, and ROM. QUESTIONS/PURPOSES We asked: (1) In complex elb...
