Recovery Times

Soft tissue injuries (muscle, ligament, tendon as examples): 1-3 months IC, 2 wk-1.5 months RL.
Complex facial fractures: 2 - 4 months IC, 1-2 months RL.
Minor spinal injuries: 3-6 months IC, 1.5-3 months RL.
Spinal fractures: 1 year IC, 6 months RL.
Hip fractures: 6 months IC, 3 months RL.
Arm or leg fractures, most other bones: 6-8 weeks IC, 3-4 weeks RL.
Major joint dislocations: 6 months IC, 3 months RL.
Injuries affecting nerve supplies to tissues: 3-12 months IC, 1.5-6 months RL.
Minor head injuries: 3 months IC, 1.5 month RL.
Spinal cord or brain injuries: 1 year IC, 6 months RL.
Upper limb amputations: 3-6 months (assuming survival) IC, 1.5-3 months RL.
Lower limb amputations: 3-12 months (assuming survival) IC, 1.5-6 months RL.
Open wounds: 1-3 weeks IC, 4 days-1.5 weeks RL.
Brandings: 3-6 weeks IC, 1.5-3 weeks RL.
First degree burns (redness, pain, minor swelling, but no blistering): 3 to 6 days IC, 1 to 3 days RL; the superficial skin layer over the burn may peel off in 1 or 2 days IC.
Second degree burns (blisters, severe pain, and redness): 4 days to 3 weeks IC, 2 days-1.5 weeks RL. High chance of infection.
Third degree burns (skin may look waxy, leathery, or charred. There may be little or no pain at first because of nerve damage): weeks to months IC, may be fatal.
Penetrating injury (chest and abdomen): High chance of fatality. Assuming survival, bed rest for at least 3 weeks IC (1.5 weeks RL), no strenuous activity for 2 months IC, 1 month RL.
