Bilateral scapholunate dissociation with degenerative arthritis

Incidence of Bilateral Scapholunate Dissociation in Symptomatic and Asymptomatic Wrists

“…Hergenröeder and Penix presented a case of an incidental finding of bilateral SLD with no preceding trauma. 6 They hypothesized that synovitis in conjunction with repetitive microtrauma or activities of daily living might be a predisposing factor to ligamentous disruption. In a small case series, Gharbaoui et al suggested congenital laxity, repetitive microtrauma, and synovitis as possible causes of the bilateral findings.…”

“…Adding to the dilemma in treating this condition are published reports showing bilateral radiographic findings in patients with unilateral symptoms. [3][4][5][6] These studies all cite small numbers of patients and imply that bilateral findings occur infrequently.…”

“…[3][4][5][6] If, however, SLD is more commonly present bilaterally than unilaterally, other factors such as congenital, developmental, or degenerative influences might play an important role in its etiology and evolution and, therefore, should be carefully considered in treatment decisions and in guiding future research.…”

Bilateral traumatic scapholunate dissociation: Case report

“…Vance et al reported a case of asymptomatic bilateral SLD, he mentioned that ligamentous laxity could be a causative factor [8] . Hergenroeder et al reported a case of bilateral atraumatic SLD for which they suggested a multifactorial causation combining congenital ligamentous synovitis, and minor or repetitive trauma [9] . In the case we presented, the patient had bilateral traumatic wrist injuries, intraoperatively, scapholunate ligaments were found to avulsed bilaterally.…”

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

“…Not every wide scapholunate gap or scapholunate dissociation may be caused by an acute traumatic ligament rupture because the contralateral wrist frequently shows the same anomaly (Picha et al., 2012). A bilateral wide scapholunate joint space may be the result of ligamentous laxity or other congenital or degenerative disorders, such as synovitis or repetitive microtrauma (Gharbaoui et al., 2005; Hergenröeder and Penix, 1981). Bilateral wide scapholunate gaps have been reported previously, mostly in small groups of patients (Gharbaoui et al., 2005; Hergenröeder and Penix, 1981; Jones, 1988; Lans et al., 2018; Linscheid et al., 1972; Picha et al., 2012; Vance et al., 1979).…”
