Compared to staged procedures with an interval months apart, staged sequential arthroplasty with a 7- to 10-day interval during one hospital admission is more efficient, as it facilitates earlier rehabilitation without higher complication rates, and entails shorter hospital stays.

In elderly women with compromised bone quality, extra care is needed to achieve better fitting so as to avoid iatrogenic metaphyseal fractures. Under-sizing or cementing of the prosthesis is recommended when encountering difficulties.

If closed reduction is unsuccessful, open reduction and open medial placement of crossed Kirschner wires can provide reliable results. The small medial incision provides a viewing point for entry of the wire and prevents iatrogenic injury of the ulnar nerve. It is cosmetically more acceptable and can be extended to facilitate open reduction.
