“…Although the size difference was not statistically significant, it does seem that the radiolunate articulation is not entirely exempt from arthritic changes as is commonly believed. This finding is supported by a study on SL dissociation by Lane and colleagues (2010). They found a number of cases of radiolunate arthritis in SL disruption without involvement of the radioscaphoid joint.…”

Treatment of scaphoid fractures has been focused mainly on achieving union, with less attention to restoring normal scaphoid shape and orientation. Malalignment of one carpal bone will disrupt the kinetics of the entire wrist. The dorsal intercalated segment instability deformity associated with scaphoid waist nonunion is a nondissociative form of carpal instability. It has to be reduced in the treatment of scaphoid waist nonunions to avoid kinetic problems that will lead to arthritic changes. Computerized tomography scanning has become indispensable to visualize the humpback deformity clearly. Different techniques may be used to restore the normal anatomy of scaphoid, from non-vascularized graft to arthroscopic bone grafting, and also the option of vascularized bone grafting.

“…White et al [18] proposed a method of scoring scaphotrapeziotrapezoidal arthritis based on objective joint space narrowing, sclerosis, and irregularity of the joint space. Another recent study of patterns of radiocarpal arthritis uses only subjective joint space narrowing agreed upon by three surgeons as the defining feature of arthritis [9]. Trapeziometacarpal arthritis has been graded based on subjective joint space narrowing and size and presence of osteophytes as well as number of joints involved [4].…”

Background Osteoarthritis of the radiocarpal joints is commonly encountered by hand surgeons. To date, there is no well-defined method of radiographically grading osteoarthritis of the wrist. Methods Preoperative radiographs of 48 patients undergoing wrist arthroscopy were evaluated retrospectively. Images were graded subjectively by five surgeons based on overall severity of arthritis, osteophytes, subchondral cysts, and subchondral sclerosis. The joint space height (JSH) ratio was calculated by measuring the space of the mid-radioscaphoid and mid-radiolunate joints and dividing each by the height of the capitate. Arthroscopic grading of arthritis was obtained from operative records and compared to subjective and objective grades. ANOVA testing evaluated for statistical significance with p<0.05. Inter-rater and intra-rater reliability was determined using Pearson's correlation analysis and Cohen's kappa coefficient. Results Objective measurement using the JSH ratio demonstrated a significant decrease as arthroscopic arthritis grade increased for both radioscaphoid and radiolunate joints. Subjective grading of radioscaphoid and radiolunate joints was able to detect moderate/severe, but not mild arthritis. Subjective grading underestimated the degree of arthritis, particularly in the radiolunate joint. Inter-rater reliability was better for objective compared to subjective grading. Conclusions Subjective grading of wrist arthritis can detect moderate/severe radiocarpal arthritis but poorly evaluates early arthritis and underestimates severity. Objective grading using the JSH ratio accurately grades radioscaphoid arthritis and detects early radiolunate arthritis. The JSH ratio more accurately assesses radiocarpal arthritis compared with subjective grading. As there currently is no accepted method to radiographically grade wrist arthritis, the JSH ratio represents a promising option.

“…Lane et al described a pattern of degeneration that included scapholunate dissociation with radiolunate arthritis and sparing of the radioscaphoid joint space. 2 They found a total of 21 wrists in 17 patients with radiographic radiolunate arthritis without evidence of radial scaphoid narrowing despite some degree of scapholunate instability in most of these cases. 2 We observed a similar "alternative" pattern of OA that involves the lunocapitate joint but did not include the radioscaphoid joint.…”

Isolated Lunocapitate Osteoarthritis—An Alternative Pattern of Osteoarthritis

2014

Introduction?Osteoarthritis (OA) in the wrist usually develops in a pattern described as scapholunate advanced collapse (SLAC). We observed an alternative pattern of OA that involves the lunocapitate joint in isolation with minimal involvement of the radioscaphoid articulation. Case Series?The series was observed from a series of 100 wrist radiographs that were retrospectively reviewed. In order to characterize the alternative pattern of OA, we compared demographic data, presentation, and physical and radiographic examination characteristics between the patients with lunocapitate OA and SLAC wrists. Fifteen radiographs showed OA, nine had a SLAC pattern, and six had lunocapitate OA. The demographics were similar, but the clinical presentation was different. The patients with lunocapitate OA had less tenderness over the snuffbox (P?
