Objectives:
To examine the relationship between muscle atrophy, ambulatory ability, and fracture type, and to make a specific rehabilitation regimen for each fracture type.
Design:
Observational study.
Setting:
Public hospital.
Participants:
Consecutive patients (N=53) with hip fracture (mean age, 83.6y) who underwent operative treatment.
Interventions:
Not applicable.
Main Outcome Measures:
The ambulatory ability score and the cross-sectional areas of lower-limb muscles as measured on computed tomography scans.
Results:
Muscle atrophy was not related to fracture type. Although the mean ambulatory ability score decreased significantly from 4.5+/-0.3 points prior to injury to 3.0+/-0.6 points 1 month postadmission, the degree of muscle atrophy was not associated with the decrease in ambulatory ability.
Conclusions:
It seems likely that other factors are more important than muscle atrophy and fracture type in determining recovery after surgical repair of a fracture and that there is no need for rehabilitation regimens based on fracture types.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
