STUDY DESIGN Retrospective cohort study. OBJECTIVE To compare perioperative characteristics of stand-alone cages and anterior cervical plates used for anterior cervical discectomy and fusion (ACDF). METHODS We reviewed 40 adult patients who received a stand-alone cage for elective ACDF and matched them with 40 patients who received an anterior cervical plate. We statistically compared opera...

We retrospectively compared wrist arthrodesis using the Mannerfelt technique in 19 or an AO-plate in 23 patients with long-standing rheumatoid arthritis. The mean follow-up was for 76 months. Compared with the Mannerfelt fusion group, patients in the AO-plate group reported greater satisfaction with their wrist function (74% vs 37%, p = 0.015). Complications were reported in six wrists in the A...

A common source of error when detecting heel-strike moments utilizing split force-plate treadmills is unwillingly stepping on contra-lateral force-plate. In this study, we quantified this error when heel-strike was detected based on such erroneous data and compared three methods to investigate how well the heel-strikes and stride-intervals were detected with erroneous data. Eleven subjects walk...

A finite element analysis was carried out to determine the optimal plate placement for pantarsal arthodesis. Three different plate placement scenarios were considered: cranial, lateral, and caudal. Under similar loading conditions, the finite element results showed that the cranial and lateral plates experienced stresses surrounding the metatarsal screws which may indicate screw loosening or fa...
