Factors that are all important to the outcome of the repair are, Provide wound care keep the wound dry and clean and monitor the wound for signs of infection, Commence scar management early to prevent adhesions. Collagenous structures such as tendons and ligaments are normally hypointense on MR imaging due to internuclear dipole interactions, which result in lower signal from protons bound to collagen. A limited field of view (usually 16 cm or less) is needed to achieve diagnostic spatial resolution. Available from.

Factors that should be considered when deciding the appropriate treatment include[10]: The physiotherapists task is to improve the functionality of the hand, with the intention of achieving the pre-injury condition. Axial T1-weighted (left) and fast spin echo T2-weighted (right) images through the medial cuneiform reveal thinning of the tendon, increased intrasubstance signal on the T2-weighted image, and splitting of the tendon (arrows). Patients with an extensor tendon injury can be treated in two ways, surgically or conservatively (namely splinting). ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Anterior tibial tendon rupture: results of operative treatment. The function of these tendons is to extend the wrist and the fingers. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). This can make it difficult to straighten your fingers, Patient unable to extend actively, but tenodesis remain normal, Radiographs are recommended because associated injuries of surrounding structures are common. Alongside the tibialis anterior and the extensor hallucis longus, the extensor digitorum longus is known as one of the leg extensors.
