The effects of various load paths and different loads on the load transfer characteristics of the wrist

Treatment of isolated perilunate and lunate dislocations with combined dorsal and volar approach and intraosseous cerclage wire

“…18 With the volar approach the rent in the space of Poirier, which often extends into the important volar ligaments, was repaired. This volar repair was augmented with a dorsal repair using minisuture anchors if there was sufficient dorsal ligament substance and supplemented with K-wires across the lunotriquetral articulation.…”

Comparison of the “Contact Biomechanics” of the Intact and Proximal Row Carpectomy Wrist

“…Another difference in design is our loading technique using wrist flexor and extensor tendons, which contrasts with the loading by Viegas et al 20 through the second and third metacarpals. However, Viegas et al 23 did show no difference in load transfer results between loading through the second and third metacarpals, through all 5 metacarpals, or through weights suspended from the wrist flexor and extensor tendons.…”

The Effect of Distal Radius Locking Plates on Articular Contact Pressures

“…In a study conducted by Charlton et al 4 of ankle joint pressures after transepiphyseal screw fixation of the tibia, the specimens were loaded with much higher forces: body weight (set at 50 kg or 490 N), twice body weight, and 5 times body weight. We chose 103 N because that value has been reported in the literature [5][6][7][8] and because we were concerned about the strength and integrity of the distal radius locking plate at higher loads. It is possible that with higher loads in the distal radius, changes in articular contact forces might become more evident.…”

“…Each forearm was loaded with a 103-N force, which is a force similar to those used in several previous studies. [5][6][7][8] This loading protocol allowed the sensors to be calibrated before testing, as per the recommendations of the manufacturer.…”

“…Our loading protocol was based on those used in previous studies [5][6][7][8] and simulated an activity such as rising from a chair using the hands for push-off. Each specimen was loaded during a 10-second period.…”
