Confronting hip resurfacing and big femoral head replacement gait analysis
Improved hip kinematics and bone preservation have been reported after resurfacing total hip replacement (THRS). On the other hand, hip kinematics with standard total hip replacement (THR) is optimized with large diameter femoral heads (BFH-THR). The purpose of this study is to evaluate the functional outcomes of THRS and BFH-THR and correlate these results to bone preservation or the large femoral heads. Thirty-one patients were included in the study. Gait speed, postural balance, proprioception and overall performance. Our results demonstrated a non-statistically significant improvement in gait, postural balance and proprioception in the THRS confronting to BFH-THR group. THRS provide identical outcomes to traditional BFH-THR. The THRS choice as bone preserving procedure in younger patients is still to be evaluated
Isolated Subtalar Distraction Arthrodesis Using Porous Tantalum: A Pilot Study
Background: During reconstructive procedures of the hindfoot, a
structural graft is often needed to fill gaps. To eliminate donor site
morbidity and limited availability of autografts, porous tantalum was
used.
Methods: Eighteen patients who underwent subtalar joint distraction
arthrodesis by means of trabecular metal augment were reviewed
retrospectively. The results were evaluated clinically, with the
American Orthopaedic Foot & Ankle Society (AOFAS) score and the visual
analog scale (VAS) for pain, and were assessed radiologically. The mean
follow-up period was 18 months.
Results: Computed tomography showed sound fusion. There was a marked
increase in AOFAS scores and a decrease in VAS scores. Arthrodesis was
achieved in all cases with no major postoperative complications.
Radiographically, there was a marked increase in all measured parameters
(talocalcaneal angle, talocalcaneal height, talar declination angle),
and the intraoperatively achieved correction was maintained at the last
follow-up visit.
Conclusion: Our data suggest that porous tantalum may be used as a
structural graft option for subtalar arthrodesis
