Bending test results of first metatarsophalangeal joint after arthrodesis with medially or dorsally positioned locking plate and lag screw.
Opis
The Dataset contains the results of the bending test of first metatarsophalangeal (MTP1) joint specimens after arthrodesis.
Three groups of samples were created depending on the MTP1 arthrodesis method:
- group with medially positioned locking plate, samples P01-P02, P04-P07, P22;
- group with dorsally positioned locking plate and lag screw, samples P08-P14;
- group with medially positioned locking plate and lag screw, samples P15-P21.
The same short titanium locking plate (Medgal) and six 2.4 mm locking screws were used in all groups. The artificial models of metatarsal bone and proximal phalanx were created based on freely accessible STL geometry of the human foot (https://www.thingiverse.com/thing:22628). The geometry was scaled and cut to prepare bones for arthrodesis and fixation in dedicated steel jigs. The artificial bone models were additively manufactured with the fused filament fabrication (FFF) method using polylactide (PLA) material in Ultimaker 3 Extended 3D printer.
The bending test of total 21 samples was performed in a Zwick/Roell Z10 universal testing machine (UTM). The shaft of the metatarsal bone was clamped in stainless steel jig, while the“distal” end of the proximal phalanx was fixed in stainless steel clamp, which was connected to a traverse of UTM. A preload of 1 N and constant vertical displacement increment of 5 mm/min of the traverse were applied in the tests to simulate quasi static loading conditions. The tests were stopped after specimens failure.
The UTM file has (.txt) extension and contains: the time of the test (in s, 2nd column), force (in N, 3rd column), traverse displacement (in mm, 4th column).
