The capsular incision is then continued in the radial direction splitting the dorsal intercarpal
ligament, aiming towards the base of the thumb, making a sideways "V" capsular incision, with the capsule ending up as a radially based flap.
PRC may be better for older patients because it has a quicker recovery period, gives equal grip strength to intercarpal
fusion and usually results in more wrist motion," Dr.
Watson HK et al did limited triscaphoid intercarpal
ortho disease for rotatory subluxation of scaphoid (5).
The vessels on the dorsal aspect of the wrist originate from the dorsal intercarpal
arch, and occasionally from the dorsal branch of the interosseous artery.
The diagnosis of intercarpal
ligamentous injury in the absence of a gross deformity is difficult with plain radiographs, ultrasound, arthrograms, and even magnetic resonance imaging (MRI).
One option, intercarpal
fusion, maintains motion at the radiocarpal joint.
There was evidence of synovitis in the intercarpal
joints and tenosynovitis of the extensor pollicis brevis (Figure 3) and the abductor pollicis longus.
6) The differential diagnostic list in patients with radial wrist pain should also include C6 cervical radiculopathy, intersection syndrome, intercarpal
instabilities, scaphoid fracture, and arthroses of the intercarpal
(IC) and radiocarpal (RC) joints.
Evaluating instability requires visualizing not only the radiocarpal joint but also the midcarpal joint, since any incongruity associated with intercarpal
instability is often more effectively assessed at the midcarpal joint.
5) The palmar portion of the LTL, dorsal radiocarpal ligament, and dorsal intercarpal
ligament play the most significant roles in LT stability.
Viable surgical options include: synovectomy, intercarpal
fusion, interposition arthroplasty, silicone spacers, joint arthroplasty, and arthrodesis.
7,8) The observation that congenital carpal fusions or coalitions are frequently without pain, weakness, or instability encouraged the concept of intercarpal
arthrodesis to eliminate not only the arthritic articulations but to also maintain mobility in the intact joint surfaces.
