Fifth Metatarsal Fracture Immobilization
Application of a cast, splint, or rigid fracture boot specifically designed for fifth metatarsal fractures to maintain alignment and promote healing. Often includes limitation of weight-bearing for a designated period.
Intramedullary Screw Fixation
Surgical insertion of a screw along the fifth metatarsal shaft to stabilize stress fractures or displaced fractures that are at risk for non-union. This is particularly considered for zone 2 and zone 3 fractures with poor healing potential.
Additional treatment options
Inflammatory and Pain Management
Appropriate use of anti-inflammatory medications and analgesics to manage swelling and discomfort during the healing phase. Treatment duration and intensity varies based on fracture severity and patient tolerance.
medicationPost-Fracture Foot Conditioning
Targeted exercises to restore strength in the lateral foot muscles, improve ankle range of motion, and address any gait abnormalities following immobilization. Includes proprioception training and gradual return to impact activities.
physical_therapyWeight-Bearing Activity Modification
Temporary adjustment of daily activities and exercise routines to protect the healing fifth metatarsal. Includes use of crutches or walkers initially, with gradual transition to normal weight-bearing as healing allows.
