Fig. 1.715 Transverse sonogram of the plantaromedial Fig. 1.716 Transverse sonogram of the
aspect of the DFTS clearly showing a mature and large plantarolateral aspect of the DFTS. The lateral
adhesion from the medial edge of the SDFT to the edge of the SDFT is abnormal and the manica
plantar sheath wall. Note also the damaged medial edge flexoria is not visible. Instead, a coiled-up mass
of the SDFT, the absence of the origin of the manica of damaged tissue is visible laterally. This was
flexoria and the poor delineation of the medial DDFT. confirmed at tenoscopy as a severely damaged manica.

Tenoscopy
1.717
Tenoscopy is both a diagnostic and therapeutic
technique. It provides excellent visualisation of the
sheath cavity and synovial surfaces and is there-
fore the technique of choice to confirm adhesions
(Fig. 1.717) and tendon lesions (Fig. 1.718) that
communicate with the sheath. It also enables treat-
ment of many conditions. Disadvantages include
its invasiveness, the need for general anaesthesia
(although it may be possible in some cases to perform
it standing under regional analgesia) and the inabil-
ity to explore the tendon parenchyma or structures
outside the sheath. Tenoscopy is complementary to
ultrasonography and should be recommended when-
ever there is suspicion of a luminal lesion that may be
addressed surgically or in the absence of a definitive
