“…A single-column die-punch fracture of the middle column frequently occurs when the radiocarpal joint is in a neutral position and the axial force is not severe. However, single-column die-punch fractures of the distal radius are rare and double-column die-punch fractures are commonly encountered in the clinic (2). In the present study, the incidence of single-column die-punch fractures of the distal radius was 0.70%, whereas the incidence of double-column die-punch fractures of the distal radius was 4.70%.…”

“…The radial column of the distal radius mainly stabilizes the wrist and controls rotation and its fracture line is usually horizontal (11)(12)(13)(14). Different types of die-punch fractures may occur, depending on the type of impact and stress, the position of the wrist, and the effects of local anatomy and bone condition (2,5,11). A single-column die-punch fracture of the middle column frequently occurs when the radiocarpal joint is in a neutral position and the axial force is not severe.…”

“…Subsequently, fractures of the articular surface of the lunate fossa caused by an axial force and transferred via the lunar bone to the lunate fossa were collectively referred to as die-punch fractures of the distal radius. The most typical manifestation was that of a collapsing fracture of the articular surface (2,3). Die-punch fractures of the articular surface of the distal tibia, of the posterior articular surface of the calcaneus and of the articular surface of the patella have also been described (4)(5)(6).…”

“…Due to differences in the extent and complexity of force at the time of injury, wrist position and bone condition, die-punch fractures may not only affect the ulnar demifacet of the distal radius but also the radial demifacet of the distal radius. These fractures include articular surface collapsed fractures and articular surface split fractures, as well as marginal fractures on the volar or dorsal side (2). According to the 'three-column theory' of distal radius fractures proposed by Rikli and Regazzoni (7) (Fig.…”

The present study aimed to classify double-column die-punch fractures of the distal radius according to imaging data, and to evaluate their clinical features. A retrospective analysis of imaging data derived from 498 patients diagnosed with a double-column die-punch fracture of the distal radius was performed. The fractures were divided into those with middle-column avulsion with fracture of the radial-column articular surface (type I), those with middle-column collapse with fracture of the radial-column articular surface (type II), those with middle-column collapse with fracture of epiphysis of the radial column (type III) or mixed-type fractures (type IV). The intra-and inter-observer consistency between assessors was analyzed with kappa statistics. The patients with double-column die-punch fractures of the distal radius were followed up. There were 21 cases of type I fracture, 135 cases of type II fracture, 130 cases of type III fracture and 212 cases of type IV fracture. The intra-observer kappa coefficient ranged from 0.810-0.861, whereas the inter-observer kappa coefficient range was 0.830-0.876, with high consistency. Following 13 months of follow-up, the patients were assessed for functional recovery of the wrist and hand using the Gartland-Werley scoring system. The analysis indicated that in 95.78% of the patients, wrist function was rated as excellent or good (n=477), while in 4.22% of patients it was rated as fair (n=21), mainly due to the development of post-traumatic arthritis of the wrist following inappropriate therapy. All of the cases were type IV and type III fractures. These data demonstrated the application of a novel classification system named the Three-Column Classification, used to classify double-column die-punch fractures of the distal radius. This method reflected the mechanisms and severity of the fractures, conforming to the principle of AO fracture classification. Furthermore, it exhibited high consistency and may provide reference values for clinical diagnosis, treatment and prognostic evaluation.

“…Moreover, clinical therapeutic decisions are often based on imaging parameters, and weight-bearing radiographs are commonly used when calculating measurements for preoperative evaluation. 2,3 Recent developments in computed tomography (CT) and magnetic resonance imaging (MRI) scanner design also allow sectional imaging of the lower extremities with patients in an upright standing position. 4,5 This review offers an overview of the different techniques used in the imaging of the lower limbs under load, with particular focus on the results and the advantages over conventional imaging.…”

Clinical management of several pathologies of the lower extremity joint relies on instrumental imaging evaluation. The assessment of joint changes with physiologic load requires studies using positions with the patient standing. Weight-bearing radiographs are the mainstay for the evaluation of several conditions such as knee osteoarthritis, pes planus, and hallux valgus, in particular to obtain measurements of articular parameters, especially for presurgical studies. In the last few years, dedicated magnetic resonance imaging and computed tomography scanners have also been developed to obtain high-resolution, multiplanar, and sectional images of the lower extremity joints during weight-bearing. These techniques provide detailed information on joint structure modifications under load in both physiologic and pathologic conditions to improve the diagnostic accuracy of weight-bearing studies.
