AO and Frykman's classifications of Colles' fracture: No prognostic value in 652 patients evaluated after 5 years

Long-Term Outcome of Nonsurgically Treated Distal Radius Fractures

“…Several other investigators have also reported the lack of correlation between clinical outcome and fracture class. 4,40,41 In the present study, however, the radiological fracture displacement was found to correlate to the GOBC score: patients classified as fair or poor were found to have had both more initial and also remaining fracture displacement. In a 10-year follow-up study of 55 patients, initial and remaining radial shortening, but not dorsal angulation, was correlated to function at follow-up examination.…”

The radioulnar joint in distal radial fractures: A review

“…There are no radiological markers in patients with peripheral TFCC-tears (Lindau et al 1997(Lindau et al , 2000a or laxity of the DRU-joint (Lindau et al 2000a, b). This is consistent with previous studies where outcome showed no correlation with fracture classi cation (Flinkkilä et al 1998) or fracture of the ulnar styloid (Villar et al 1987, Aro and Koivonen 1991, Warwick et al 1993, Poirier 1994.…”

“…This is partly why Frykman's classi cation (1967) used each fracture type (extraarticular = I, radiocarpal = III, radioulnar = V, radiocarpal and radioulnar = VII) with a worse counterpart when the ulnar styloid was fractured (types II, IV, VI and VIII). However, the usefulness of Frykman's classi cation has been questioned (Andersen et al 1996), since others have reported no correlation between this classi cation and outcome (Flinkkilä et al 1998). Furthermore, several studies have found no correlation between ulnar styloid fractures and the end-result (Villar et al 1987, af Ekenstam et al 1989, Aro and Koivonen 1991, Warwick et al 1993, Poirier 1994, Lindau et al 2000a).…”

Adult distal radius fractures classification systems: essential clinical knowledge or abstract memory testing?

“…It does not, however, take into consideration the extent of fracture displacement, degree of comminution or shortening of the radius, so its ability to guide treatment and predict prognosis is limited. 2,18 Critics cite great difficulty in agreeing on the involvement of the radioulnar joint as one of its main downfalls. 19 Studies evaluating the reliability and reproducibility of the classification showed that there was fair to moderate agreement between observers, with kappa statistics ranging from 0.22 to 0.38 for reliability and from 0.26 to 0.6 for reproducibility.…”
