Rahman, H.S.; Abu Osman, N.A.; Yahud, S.; Ahmad, T.S.; Ng, E.S (2007) A study of the external finger fixator to correct flexion deformity. Journal of Biomechanics, 40. S183. ISSN 0021-9290
Severe fixed flexion deformities at the fingers are common injuries that can lead to pain and stiffness when treated improperly. The damage varies from a sprain of the collateral ligaments to an all-round comminuted fracture-dislocation. The flexion deformities occur because of a variety of issues including fractures (broken bones), burns, tissue expansion, facial contracture and finger joint dislocation . With conventional splints it is difficult to apply an effective torque without causing pain and inflammation due to pressure on the skin. The objective of the study is to develop a new design for external finger fixator to correct severe fixed flexion deformity. Siow et al. (1999) conducted a clinical trial on three patients by using mini external fixator where each of them had severe fixed flexion of deformity. The device was applied up to 44 days and post-operative observation showed that the effected finger can extend up to 75% from the initial range of motion . The use of this external fixator for correction of rigid soft tissue deformities of the hand has proved that it is not only feasible, but works well.
