BENNETT FRACTURE Bennett fracture is an intraarticular two-part fracture of the ulnar side of the base of the first metacarpal often sustained when punching a hard object. Here's a quick summary. • Intraarticular two-part fracture of the ulnar side of the base of the first metacarpal • The ulna portion of the base of the thumb remains in place, whereas the longer radial fragment subluxes or dislocates due to the pull of the abductor pollicis longus muscle • Associated complications occur late and include stiffness, arthritis and malunion • Mechanism: Axial force applied to the thumb in flexion (blow with the fist) • Exam: Swelling and tenderness at the base of the thumb with limited range of motion • ED Management: Pain control, immobilize • Splint: Thumb spica • Ortho consult: No, if <1 mm displacement; Yes, if >1 mm displacement • Disposition: Discharge home with close orthopedic follow-up within the next 2-3 days as these fractures often require operative management MH/CCF/CWRU EM Res @MetroHealth_EM #Bennett #Fracture #Thumb #Metacarpal #Radiology #XRay #Diagnosis #Management #Hand #Orthopedics #MSK
