Fractures of the Hand Flashcards
Proximal Fracture (DX)
-a metacarpal fx (ex. boxer’s fracture of 4th and 5th fingers)
Carpal Fractures (DX)
-fxs to individual carpal bones
Which carpal fracture is most commonly seen and missed in wrist injuries?
scaphoid
Which carpal fracture is associated with Keinbock’s disease?
lunate
What are avulsion injuries?
-occur when the tendon separates from the bone and its insertion and removes bone material with the tendon
Mallet Finger (DX)
- avulsion of the terminal tendon
- characterized by drooping of the finger, cannot extend on its own power
Mallet Finger (OT)
-splinted in full extension for 6 weeks
Boutonniere Deformity (DX)
- disruption of the central slip of the extensor tendon
- characterized by PIP flexion and DIP hyperextension
Boutonniere Deformity (OT)
- splinted in extension
- isolated DIP flexion exercises are performed
Swan Neck Deformity (DX)
- injury to the MCP, PIP, or DIP joints
- characterized by PIP hyperextension and DIP flexion
Swan Neck Deformity (OT)
-PIP splinted in slight flexion
What are the 3 phases of healing? What does each involve?
- Inflammation - provides the cellular activity needed for healing
- Repair - forms the callus for stabilization
- Remodeling - deposits bone
What are some potential complications of fracture healing? *What other factors may impact healing?
- misaligned fracture
- pain
- decreased nutrition to the area
- decreased healing potential
- age and bone disease
What determines the safe time frame for movement versus protection of a fracture?
- fracture type
- stage of healing
- physician orders
How and when are the outcomes of hand fractures assessed?
- the Quick DASH
- before AND after therapy
