What should you know about fifth metacarpal fracture cast?

The fifth metacarpal is the hand bone leading to the little finger. A cast or splint limits movement so the fracture can be checked as it heals. The choice depends on the fracture's position, stability, skin condition, swelling, and whether the finger alignment is acceptable. Some injuries are managed with casting alone; others need a Closed Reduction before a cast, or Fracture Fixation Surgery when alignment cannot be maintained. Fracture Casting explains the wider process. Fibreglass Cast Material and Plaster of Paris are two materials a clinician may consider.

Keep the cast dry and do not insert objects inside it to scratch the skin. Elevate the hand when swollen, move the free fingers as instructed, and attend planned checks so circulation, alignment, and comfort can be reviewed. Do not trim, loosen, or remove the cast yourself. After immobilisation ends, Physiotherapy may help restore finger motion, grip, and everyday hand use. Follow the treating team's limits on lifting and sport because a comfortable hand may still need protection.

Contact the treating service promptly if the cast becomes wet, cracked, loose, tight, or causes rubbing. Seek urgent care for worsening pain despite elevation, increasing numbness or tingling, blue or pale fingers, inability to move the fingers, severe swelling, or a cold hand. Fever, spreading redness, bad odour, or discharge may signal a skin or wound problem and also needs prompt review.

Is the fracture aligned and stable in this cast? How should I protect it during washing and sleep? Which finger movements are safe? When is the next review or imaging check, and what will guide removal or a change of support?
