Abstract
Mobility is an important factor in the rehabilitation phase for #hipfracture patients. Among many factors affecting postoperative
mobility, stability of the stem following #hemiarthroplasty is considered
crucial for early mobility. The purpose of this study was to compare
early postoperative mobility in patients with cemented and uncemented
hydroxyapatite coated Furlong hemiarthroplasty. We performed a
retrospective comparative study to compared two groups of patients who
had either cemented, or #hydroxyapatite (HA) coated uncemented
implants over a period of six months. The groups were matched for their
age, sex, pre-fracture mobility and accommodation prior to injury.
Their early post-operative (day1-day7) mobility was assessed based on
their walking distance, need for support, and pain level. The length of
hospital stay and discharge destinations were also recorded and compared
between the groups. Each group had 22 patients. The average age
was 84 years (range, 74-95). The average pre-fracture mobility score was
5.5. The average post-operative mobility for cemented group was
2.7 at day 1 and 6.3 at day 7. For the uncemented group the average
post-operative mobility at day 1 was 3.7, and at day 7 it was 6.9.
Hospital
stay was slightly longer in the cemented group. We conclude that early
post-operative mobility is slightly better in patients who had HA coated
uncemented implants. The average hospital stay is longer in the group
with cemented implants.
