“…This is similar to the results of previous studies investigating post-arthroscopic chondrolysis of the shoulder (24,25). SLAC tends to be seen in older patients (26). The mean time of disease onset (development interval of demonstrable joint space narrowing after arthroscopy) was 1.63 years in patients with PRCC.…”

Background Since the diagnosis of post-arthroscopic chondrolysis is very difficult, it can be underdiagnosed and confused with other diseases in clinical practice. Purpose To propose imaging features of post-arthroscopic radiocarpal chondrolysis (PRCC) and to compare these with osteoarthritis associated with scapholunate dissociation which are the most common misdiagnoses of PRCC. Material and Methods To identify missed diagnoses of PRCC, 994 magnetic resonance imaging scans performed in 910 patients were retrospectively reviewed. After the identification of 73 patients who exhibited significant radiocarpal cartilage loss, 11 were diagnosed with PRCC. Since scapholunate advanced collapse was the most common incorrect diagnosis of PRCC (4/11), the imaging findings were compared among the 11 patients with PRCC and 14 patients with osteoarthritis caused by scapholunate dissociation who were diagnosed in the same period. The following imaging features were evaluated: scapholunate dissociation; the center of disease and grade of radiocarpal joint destruction; characteristics of bone marrow edema; the presence of radial styloid and distal scaphoid osteophytes; and the extent of joint effusion and synovitis. Results The imaging diagnosis of PRCC was significantly differentiated from osteoarthritis associated with scapholunate dissociation based on occurrence at a younger age, bone marrow edema crossing the joint, center of disease in the proximal radioscaphoid joint, and absence of radial styloid and scaphoid osteophytes ( P < 0.05). PRCC occasionally presented with arch-shape bone marrow edema based on the proximal carpal row. Conclusion The diagnosis of PRCC can be aided if its characteristic imaging findings are differentiated from other disease entities in patients with a history of arthroscopy.

“…Those causes are more commonly observed in patients with bilateral wrist changes. 28,[34][35][36] analyzed radiographs from both wrists of 1,000 people with no recent trauma, and found 67 of those cases of bilateral and 51 of unilateral SL space widening. 34 There were signs of SLAC in 26 wrists, and, of those, 9 were bilateral.…”

Despite being the second most common osteoarthritis of the wrist, little is known about scaphotrapeziotrapezoid osteoarthritis. Not all patients with this type of osteoarthritis have symptoms, and, even in those symptomatic patients, the intensity of the complaint is not proportional to the severity of the degeneration. In symptomatic patients, when the conservative treatment fails, grading classifications to help define the surgical treatment are solely based on the joint characteristics, and fail to assess the rest of the carpus.In general, most carpal degenerative processes show the same evolution pattern, which varies according to the initial injury, along with the type of deformity and the inherent instabilities. Thus, we hypothesize that the degenerative evolution due to primary osteoarthritis of the scaphotrapeziotrapezoid joint also follows a logical evolutionary sequence, similar to the one that occurs in cases of scapholunate advanced collapse (SLAC), scaphoid nonunion advanced collapse (SNAC), scaphoid malunion advanced collapse (SMAC), and scaphoid chondrocalcinosis advanced collapse (SCAC), thus resulting in scaphotrapeziotrapezoid osteoarthritis advanced collapse (SOAC). We have divided the SOAC into three groups, and considered that their treatment shall be guided by the evolutionary stage of the disease, and not by the surgeon's preferred technique.

“…SLAC is the most common pattern of osteoarthritis in the wrist (Watson and Ryu, 1986). The most frequent aetiology is believed to be a traumatic injury of the scapholunate ligament (Kitay and Wolfe, 2012), but cases of nontraumatic SLAC wrists have been reported (Pollock et al., 2010). Masmejaen et al.…”

“…Masmejaen et al. (1997) reported that bilateral SLAC wrists were extremely rare, but Pollock et al., (2010) found 11 bilateral cases out of 17 patients with SLAC wrists. Bilateral cases of SLAC wrist have also been observed in patients with calcium pyrophosphate crystal deposition disease (Chen et al., 1990).…”

Bilateral scapholunate widening may have a nontraumatic aetiology and progress to carpal instability and osteoarthritis with advancing age

It was hypothesized that bilateral widening of the scapholunate gap is relatively common in the absence of trauma and that it progresses to radiological carpal instability and scapholunate advanced collapse. Electronic files of 1000 patients with bilateral X-rays were studied in retrospect. Wide scapholunate gaps were bilaterally present in 67 and unilaterally in 51 patients. Scapholunate advanced collapse was observed in 26 patients; in nine it was in both wrists. A trauma was recorded in less than half of the patients with a bilateral wide scapholunate gap. Patients with bilateral wide gaps were younger if signs of carpal instability or osteoarthritis were absent. Bilateral scapholunate widening may not be caused by an acute trauma, but may lead to carpal instability and degenerative changes with advancing age.
