de Villambrosia et al reported a predictive model for gait recovery following hip fracture. The authors are from multiple institutions in Spain and contributors to the Spanish National Hip Fracture Registry.
Patient selection: hip fracture>= 65 years of age, FAC >= 1
Outcome: baseline gait recovery within 1 month
Parameters:
(1) age in years
(2) prefracture ambulation using the Functional Ambulation Classification (FAC)
(3) cognitive impairment
(4) ASA status
(5) surgical delay in hours
(6) early postoperative mobilization
(7) discharge destination
(8) fracture type
(9) weight bearing allowed
(10) pressure ulcer
