| Summary: | Objective: To study the differences in femoral neck fracture healing and affected limb pain
after anterolateral-approach minimally invasive total hip replacement and hemiarthroplasty.
Methods: A total of 92 patients with femoral neck fracture who received hip replacement
in our hospital between May 2013 and December 2015 were selected and randomly divided
into total hip and half hip group, total hip group received anterolateral-approach minimally
invasive total hip replacement, half hip group received anterolateral-approach minimally
invasive hemiarthroplasty, and 1 month after operation, serum was collected to detect the
levels of bone metabolism markers, osteocyte cytokines, SP and CGRP. Results: 1 month after
operation, serum PINP, PICP, BMP, TGF-β, FGF, IGF-I and IGF-II levels of total hip group
were significantly higher than those of half hip group while TRAP5b and CatK levels were
significantly lower than those of half hip group; the day after operation, serum pain media SP
and CGRP levels were not significantly different between the two groups of patients; 36 h after
operation, serum SP and CGRP levels of total hip group were significantly lower than those
of half hip group. Conclusion: The bone metabolism after anterolateral-approach minimally
invasive total hip replacement is better than that after hemiarthroplasty, and the degree of pain
is less than that after hemiarthroplasty.
