Humeral Shaft IM Nail Complications

  • Delayed union = failure to unite in 2-3 months
  • Nonunion 4-6 months
  • Malunion, nonunion, vascular, radial N(10%),
  • Radial nerve palsy-most recover in 3-4 months, pts should be placed in cock-up wrist splint, given thumb abduction and finger/wrist extension exercises to avoid contracture.  EMG at 6 wks if no signs of recovery.  Brachioradialis should be first muscle to return.  11.1% of closed fx have associated Radial nerve palsy, 0.2% in closed fx's fail to recover.  18% open fx. 60% have nerve entrapped in fx. (Bostman O, Acta Orthop Scand 1986;57:316) . (Shaz JJ, Bhatti NA: CORR 1983;172:171. (Holstein A JBJS 1963;458:1382).

Humeral Shaft IM Nail Follow-up care

  • Post-op: Posterior splint, NWB.
  • 7-10 Days: Remove splint, begin passive shoulder and elbow ROM. Stress elbow ROM. Consider Humeral fracture brace.
  • 6 Weeks: Begin strengthening exercises provided fracture union is evident on xray.
  • 3 Months: Ensure full restoration of shoulder and elbow ROM. Consider bone stimulator if union is delayed. Sport specific rehab.
  • 6 Months: return to full activities / sport.
  • 1Yr: Follow-up xrays, assess outcomes.
  • Immediate weight bearing on a plated humerus fx with the use of crutches of a walker has been shown to safe. (Tingstad, J Trauma 2000;49:278).
  • Shoulder Outcome measures.
  • Elbow Outcome measures.
