Anatomical and clinical research has shown that the entire lateral epi
condylar region is innervated only by radial nerve branches. Based on
these investigations we have developed a surgical procedure for comple
te denervation which is indicated only in resistant cases of tennis el
bow. Only one nerve pathway calls for careful exposure, otherwise dene
rvation is accomplished blindly by disinsertion of certain muscles. Th
e result of this procedure also depends on simultaneous indirect decom
pression of the posterior interosseous nerve. Excellent or good result
s were obtained in 90% on average. Results of denervation did not impr
ove by additional direct radial nerve release.
