Abstract Background Arthroscopically-assisted reduction and internal fixation (AARIF) for distal radius fractures (DRF) has been extensively described. Little information is available about AARIF in AO “B3” and “C” DRF with displaced lunate facet volar rim fragment (VRF) and volar carpal subluxation. However, lunate volar rim fragment (LVRF) may be very difficult to reduce and fix under arthroscopic control using the flexor carpi radialis (FCR) or FCR extended approaches while traction is applied. Purposes The aims were to describe our surgical technique of AARIF of partial or complete DRF with VRF and provide information about how often this technique may be necessary, based on a large DRF database. Methods The dual-window volar approach for complete articular AO C DRF with volar medial fragment was described in 2012 for performing open reduction internal fixation (ORIF). Since 2015, we have used the dual-window approach for AARIF of “B3” or “C” DRF with volar carpal subluxation. We analyzed our PAF database, searching for patients treated with AARIF in “B3” and “C” fractures. Results The dual-window volar approach is very useful when using AARIF for AO “B3” and “C” DRF with displaced VRF and volar carpal subluxation. The anteromedial part of the exposure allows a direct access to reduction and fixation of the LVRF under traction and arthroscopic control. Overall, 1% of all articular DRF in this series showed a displaced LVRF amenable to the dual-window volar approach. Conclusion It is almost impossible to access and properly fix a VRF using traction and arthroscopic control through the FCR or FCR extended FCR approach because of the stretched flexor tendon mass. The use of the dual-window approach during AARIF of AO “B3” or “C” DRF has not previously been reported. Displaced VRF are rare whether they were part of “B3” or “C” fractures. If AARIF is chosen, we strongly recommend the use of the dual-window volar approach for AO “B3” and “C” fractures with VRF. A single anteromedial approach can also be used for isolated “B3” anteromedial DRF.

The Impact

Background: The diagnosis of subtle injuries to the distal tibiofibular syndesmosis remains elusive. Conventional radiographs miss a large subset of injuries that present without frank diastasis. This study evaluated the impact of torque application on the assessment of syndesmotic injuries when using weightbearing computed tomography (CT) scans. Methods: Seven pairs of male cadavers (tibia plateau to toe-tip) were included. CT scans with axial load application (85 kg) and with (10 Nm) or without torque to the tibia (corresponding to external rotation of the foot and ankle) were taken during 4 test conditions. First, intact ankles (native) were scanned. Second, 1 specimen from each pair underwent anterior inferior tibiofibular ligament (AITFL) transection (condition 1A), while the contralateral underwent deltoid transection (condition 1B). Third, the lesions were reversed on the same specimens and the remaining intact deltoid or AITFL was transected (condition 2). Finally, the distal tibiofibular interosseous membrane (IOM) was transected in all ankles (condition 3). Measurements were performed to assess the integrity of the distal tibiofibular syndesmosis on digitally reconstructed radiographs (DRRs) and on axial CT scans. Results: Torque impacted DRR and axial CT scan measurements in almost all conditions. The ability to diagnose syndesmotic injuries using axial CT measurements improved when torque was applied. No significant syndesmotic morphological change was observed with or without torque for either isolated AITFL or deltoid ligament transection. Discussion: Torque application had a notable impact on two-dimensional (2-D) measurements used to diagnose syndesmotic injuries for both DRRs and axial CT scans. Because weightbearing conditions allow for standardized positioning of the foot while radiographs or CT scans are taken, the combination of axial load and torque application may be desirable. Clinical Relevance: Application of torque to the tibia impacts 2-D measurements and may be useful when diagnosing syndesmotic injuries by DRRs or axial CT images.
