The Effect of Radioscapholunate Fusion With and Without Distal Scaphoid and Triquetrum Excision on Capitolunate Contact Pressures

Dynamic MRI of the wrist in less than 20 seconds: normal midcarpal motion and reader reliability

“…First, we studied a relatively small cohort of 35 wrists in 19 asymptomatic volunteers. However, this cohort size is in line with prior literature evaluating clinical [5,8,[40][41][42], biomechanical [6,[43][44][45], and dynamic CT [21][22][23][46][47][48][49] aspects of wrist disorders. Although our analysis serves as a foundation for future work on normal and abnormal kinematic patterns, we did not analyze symptomatic patients or have clinical justification to correlate findings with radiography, fluoroscopy, CT, or histopathology in our asymptomatic volunteers.…”

The Biomechanical Effects of Simulated Radioscapholunate Fusion With Distal Scaphoidectomy, 4-Corner Fusion With Complete Scaphoidectomy, and Proximal Row Carpectomy Compared to the Native Wrist

“…A dorsal, ligament-sparing capsulotomy was performed to confirm that there was no evidence of midcarpal arthrosis or an intercarpal ligament injury. 23,24 All the dissections and simulated procedures were performed by a fellowship-trained hand surgeon in conjunction with a senior orthopedic resident.…”

“…25,26 The film was protected from fluid and sealed in a polyvinyl chloride film, as previously described. 24,27 After loading the film in a controlled manner and confirming its stability within the joint, the dorsal capsulotomy was repaired. The embedded proximal and distal ends of the specimen were placed in a mechanical loading system (Material Test System 858) with a 445-N load cell (Honeywell).…”

“…28 Separate trials were conducted, and the values were averaged for each specimen. 24 Method for the simulation of RSLFDDSE An RSLF was simulated using 1.6-mm Kirschner wires (Fig. 2).…”

Salvage procedure after malunited distal radius fractures and management of pain and stiffness

“…Mc Nary [67] examined ten fresh frozen cadaveric wrists with RSL arthrodesis including removal of the distal scaphoid and triquetrum. This method showed that the contact forces in the capitolunate joint could be increased by 50%.…”
