Pitfalls

• Patients with coexisting poly-neuropathy may benefit from ulnar tunnel release but should be warned that not all of their symptoms may resolve.

• Do not cross the wrist crease with a perpendicular incision or a hypertrophic scar may form.

Diagnostic Studies

Anteroposterior, lateral, and oblique radiographs and a carpal tunnel view of the right hand revealed no acute fractures, subluxations, or dislocations. A chest radiograph was normal. Computed tomography of the wrist revealed small bone fragments adjacent to the base of the fifth metacarpal predominantly along its palmar-radial aspect. The hook of the hamate appeared intact. In the presence of a normal Allen's test, Doppler studies were not performed. Nerve conduction study results are shown in Table 16-1.
