U. Bosch et al., Outcome after primary and secondary hemiarthroplasty in elderly patients with fractures of the proximal humerus, J SHOUL ELB, 7(5), 1998, pp. 479-484
Thirty-nine consecutive patients with 3- and 4-part proximal humeral fractu
res and fracture dislocations were treated with hemiarthroplasty. After an
average of 42 months (range 5 to 98 months) of Follow-up, 17 women and 8 me
n (average age 64.5 years) were evaluated with the University of California
-Las Angeles (UCLA) scale, the Constant-Murley scale, the Hospital for Spec
ial Surgery (HSS) scale, and the visual analogue scale. Fair, good, or exce
llent results were achieved in 80% of the patients on the UCLA and Visual s
cales, in 72% of the patients on the HSS scale, and in 44% of the patients
on the Constant-Murley scale. The highest correlation was between the HSS s
core and the Visual analogue score. According to the UCLA and Constant-Murl
ey results, the outcome after early (<4 weeks) humeral head replacement was
significantly better than after late (greater than or equal to 4 weeks) hu
meral head replacement (UCLA score, P = .02; Constant-Murley score, P = .01
). After early hemiarthroplasty active forward flexion was significantly be
tter (P = .035). Thus the decision to perform prosthetic humeral head repla
cement in elderly patients should be made as early as possible after trauma
.
