Surgical Treatment

In patients with a Stener lesion, repair of the torn ligament, with reattachment to the bone, is recommended. A skin incision is made and the dorsal ulnar sensory branch of the superficial radial nerve is identified and protected (Fig. 51-8). The Stener lesion is then identified (Fig. 51-9). The adductor aponeurosis is cut at

90 degrees to its fibers. The MP joint is inspected for any soft tissue interposition. The proximal phalanx is curetted (Fig. 51—10) and prepared if the avulsion is off the proximal phalanx. The proximal phalanx is drilled. A minianchor is placed in the predrilled hole (Fig. 51-11A). The UCL is then repaired using the sutures

attached to the anchor (Fig. 11B-E). The adductor aponeurosis is repaired (Fig. 51—12). The skin is then closed. Postoperatively, the patient is placed in a wrist gauntlet cast (Fig. 51—13). At 6 weeks postoperative, the patient is given a functional hand splint, therapy is begun in the AP plane, and pronation/supination exercises are completed.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
