Scapholunate dissociation associated with distal radius fractures

Abstract

Severity of the distal radius fractures is not associated with SLD. Intra-articular fractures were associated with significant increase in the prevalence of SLD. In some cases, SLD may appear after reduction in distal radius. Most cases with SLD are symptomatic, and this may be the reason of poor cases following distal radius fracture.

Management of Intercarpal Ligament Injuries Associated with Distal Radius Fractures

“…42 None of these patients received treatment of their ligamentous injury. At final follow-up, 79 patients had tenderness to palpation over the scapholunate interval with fair to poor outcomes on the Green and O'Brien rating system.…”

Open Treatment of Acute Scapholunate Instability

“…Studies have shown that failing to treat SL dissociation in patients with distal radius fracture leads to worse outcomes both clinically and radiographically. 56,58,59,61,62 Appropriate treatment, however, can provide good results. Peicha and colleagues 71 in 1999 performed arthroscopicassisted K-wire fixation of Geissler grade 3 and 4 SL injuries with distal radius fracture with predominantly excellent or good results in patients at an average of 3 years of follow-up.…”

“…[50][51][52][53][54][55][56] Rates when diagnosed radiographically range from 13.3% to 29%. [57][58][59][60][61][62] Mudgal and Hastings suggest the mechanism of this combined injury can be attributed to a combination of tensile stress in ulnar deviation and axial (compression) stress in either radial or ulnar deviation. 63,64 Overall, intra-articular fractures are associated with higher rates of SL injury but SL injury can be found in extra-articular fractures as well.…”

“…63,64 Overall, intra-articular fractures are associated with higher rates of SL injury but SL injury can be found in extra-articular fractures as well. [50][51][52][53][54][57][58][59][60]62 Diagnosis of these concomitant injuries can be difficult. In 1997, Richards and colleagues 54 evaluated 118 distal radius fractures arthroscopically and found that 60% of patients with SL injury did not demonstrate an SL gap greater than 2 mm on radiographs.…”

Does pisiform subluxation affect the postoperative outcomes in a cohort of patients with distal radius fractures?

“…Various traumas concomitantly occur around the carpal bones with distal radius fractures (DRF) [ [1] , [2] , [3] ], but some traumas may be overlooked on examination by plain radiography alone [ 2 ]. DRF are common traumas, examined not only by hand surgeons but also orthopedists.…”
