“…These results are also encouraging, and invite for further experimentation with larger samples and more measurements. New measurements such as radial shortening [32], volar and dorsal displacements [33], ulnar variance, palmar tilt and radial inclination [34] should be explored as these are widely used, but always extracted manually. Similarly, more osteoporosis-related measurements e.g.…”

Fractures of the wrist are common in Emergency Departments, where some patients are treated with a procedure called Manipulation under Anaesthesia. In some cases this procedure is unsuccessful and patients need to visit the hospital again where they undergo surgery to treat the fracture. This work describes a geometric semi-automatic image analysis algorithm to analyse and compare the x-rays of healthy controls and patients with dorsally displaced wrist fractures (Colles' fractures) who were treated with Manipulation under Anaesthesia. A series of 161 posterior-anterior radiographs from healthy controls and patients with Colles' fractures were acquired and analysed. The patients' group was further subdivided according to the outcome of the procedure (successful/unsuccessful) and pre- or post-intervention creating five groups in total (healthy, pre-successful, pre-unsuccessful, post-successful, post-unsuccessful). The semi-automatic analysis consisted of manual location of three landmarks (finger, lunate and radial styloid) and automatic processing to generate 32 geometric and texture measurements, which may be related to conditions such as osteoporosis and swelling of the wrist. Statistical differences were found between patients and controls and pre- and post-intervention, but not between the procedures. The most distinct measurements were those of texture. Although the study includes a relatively low number of cases and measurements, the statistical differences are encouraging.

“…They were partly used in combination with external fixation. However, secondary dislocation still occurred [9][10][11][12][13][14], that necessitated correction and salvage procedures [15][16][17][18][19][20][21][22][23][24][25][26][27].…”

A wide range of different classifications exist for distal radius fractures (DRF). Most of them are based on plane X-rays and do not give us any information on how to treat these fractures. A biomechanical understanding of the mechanical forces underlying each fracture type is important to treat each injury specifically and ensure the optimal choice for stabilization. The main cause of DRFs are forces acting on the carpus and the radius as well as the position of the wrist in relation to the radius. Reconstructing the mechanism of the injury gives insight into which structures are involved, such as ruptured ligaments, bone fragments as well as the dislocated osteoligamentous units. This article attempts to define certain key fragments, which seem crucial to reduce and stabilize each type of DRF. Once the definition is established, an ideal implant can be selected to sufficiently maintain reduction of these key fragments. Additionally, the perfect approach is selected. By applying the following principles, the surgeon may be assisted in choosing the ideal form of treatment approach and implant selection.

“…Despite this difference, Disabilities of the Arm, Shoulder, and Hand (DASH) scores were 14.5 and 14 for volar versus dorsal plating respectively. 22 In addition, Erhart et al 23 performed a retrospective midterm follow-up of patients with Smith or Colles type fractures and volar fixation only and subsequent development of complications. They noted that the Colles group had a significant loss of reduction; however, this could not be correlated clinically with wrist function or dorsal tilt.…”

Purpose To characterize the dorsal ulnar corner fragment with regard to size and morphology using 3-dimensional software and computed tomography (CT) scans, as it presents in lowenergy intra-articular distal radius fractures occurring in the female postmenopausal population.Methods A multicenter retrospective review was conducted to identify postmenopausal females with low-energy distal radius fractures treated surgically at level-1 trauma centers. Patients with low-energy injuries with preoperative CT scans were included. The Digital Imaging and Communications in Medicine (DICOM) data from CT scans were used to reconstruct intra-articular fracture patterns. The dorsal ulnar fragment was isolated in each CT scan and measured, then normalized based on lunate depth.Results Eighty patients met the inclusion criteria. The mean dimension measurements of the dorsal ulnar corner were dorsal surface height, 9.82 AE 5.02 mm (95% confidence interval [95% CI], 8.72e10.92); dorsal surface width, 9.06 AE 3.72 mm (95% CI, 8.25e9.88); articular surface width, 7.44 AE 3.92 mm (95% CI, 6.58e8.30); articular surface depth, 4.14 AE 2.39 mm (95% CI, 3.62e4.67). The mean lunate depth measurement (17.52 AE 1.48 mm) was used to normalize articular surface depth demonstrating that, on average, the dorsal ulnar corner comprises 23.6% of the articular surface AE 13.6% (95% CI, 20.7e26.6). ConclusionsThe mean articular surface depth of the dorsal ulnar corner fragment in this study was less than 5 mm, accounting for approximately 24% of the volar-dorsal width of the distal radius at the lunate facet.Clinical relevance These data expand current understanding of the morphology and size of the dorsal ulnar corner fracture fragment. If fixation of this fragment is a goal, surgeons may need to use longer screws that penetrate closer to the dorsal cortex than those required for extraarticular fractures or to consider alternative methods of fragment-specific fixation for adequate capture of this fragment.
