title: The use of the three-point index in the management of extra-articular distal radius fractures.
abstract: Conservative management has been the mainstay of treatment for simple extra-articular distal radius fractures. Several factors, such as quality of definitive casting, have been implicated in the risk of fracture re-displacement during follow-up. Objective assessments of the quality of casting using various indices have been documented in literature, although overall evidence remains scant, and only one study in the literature discusses the use of the three-point index (3-PI) in adults. Currently, no independent study assessing the 3-PI in adults has been documented. This retrospective study aimed to assess the 3-PI in terms of (1) predicting fracture re-displacement and (2) evaluating its practicality in everyday clinical use. We had 54 patients (47 female, 7 female), out of which 35 patients had a 3-PI greater than the suggested cutoff value of 0.8; of these, 22 went on to re-displace. The remaining 19 patients had a 3-PI below the cutoff and 14 went on to re-displace. No statistical significance was found for the 3-PI as a predictor for fracture re-displacement, although inter-observer reliability was high; its impact on clinic times (in calculating the 3-PI) remained low.
