ABSTRACT
BACKGROUND@#Joint stiffness is a frequent concern in trauma or surgery of the elbow joint. Early resumption of elbow joint motion is said to limit the complication of stiffness. The Hinged Elbow Ilizarov Fixator has been reported to be useful in the management of elbow dislocations. However, early range of motion is not consistent in these cases since elbow movement were done only through patient-initiated exercises. The use of a continuous passive motion (CPM) device can potentially resolve this issue. However, presently available continuous passive motion devices for the elbow are not compatible with the Hinged Elbow Ilizarov Fixator.@*OBJECTIVE@#The objective of the study is to determine the feasibility of using a specially designed continuous passive motion device on a Hinged Elbow Ilizarov Fixator as applied in a cadaver simulation model.@*METHODS@#A Hinged Elbow Ilizarov Fixator was fixed in the elbow of a Thiel-preserved cadaver. The specially designed continuous passive motion device was applied.@*RESULTS@#Test run showed sufficient continuous flexion-extension motion not accompanied by dislocation, subluxation, or disruption of the elbow joint. A point of stress in the current prototype was noted at the motor-screw interface. Limitations in programming and control were also noted.@*CONCLUSION@#A continuous passive machine adopted to the Hinged Ilizarov Fixator is a viable device. Further improvement in the design of the motor-screw interface needs to be made. Further improvement in programming and control are needed. Likewise, study on the safety and service life of the CPM device needs to be done.
