What is the next best step in management of this patient? Adhesions within the first and third dorsal wrist compartments. A radiograph is shown in Figure 21. (OBQ08.179) Chronic DISI deformities may be indicated for fusion procedures depending on degree of arthritis and patient symptoms. 3, Greenberg MI. Lunate fractures account for around 4% of all carpal fractures 1. The injury pattern may involve a crush injury, a FOOSH injury (Figure 18.21), or a direct blow to the dorsal aspect of the wrist. Hand therapy does not change the course of the disease; however, it can help to minimize loss of motion from the disease. A fracture to the lunate may also be associated with injury to the TFCC.
