THE MECHANICS OF MUSCULAR CONTRACTURES IN WRIST AND FINGERS

¹ Professor of Orthopaedic Surgery, State University of Iowa

In conclusion it may be pointed out again that the stated theoretical facts have a wide practical application. They are fundamental in formulating the program of treatment, not so much in regard to the technical construction of external appliances, but rather because the pathomechanics of these upper-extremity contractures point out the causal relationship of the different components of the contracture complex. By recognizing a basic or key element upon which the whole complex is built, we can decide on the most efficient point of attack for the correction. The biophysical theory of contracture gives information also as to when and how long mechanical correction is to be applied, and what changes of position conform best to the mechanical situation. It is safe to state that only by understanding the biophysics of these conditions, can one become efficient in their management and treatment.
