  • 11981 Insertion, non-biodegradable drug delivery implant
  • 11982 Removal, non biodegradable drug delivery implant
  • 11983 Removal with reinsertion, non-biodegradable drug delivery implant

Hardware Removal Etiology / Epidemiology / Natural History

  • Accounts for @ 5% of orthopaedic procedures

Hardware Removal Anatomy

  • Direct fracture healing: no fracture callus; new osseous channels form across the fracture site; rigid fixation; can occur with compression plating.
  • Indirect fracture healing: with callus formation; less rigid fixation;  intramedullary or external fixation.

Hardware Removal Clinical Evaluation

Hardware Removal Xray / Diagnositc Tests

  • Evaluate xryas for radiographic evidence of circumferential bridging external callus,

Hardware Removal Classification / Treatment

  • Retain implants for at least 12 months postoperatively to allow for bone remodeling before hardware removal. (Brumback RJ,  J Bone Joint Surg Am 1992; 74: 106-112.)
  • Achieving complete union and remodeling before implant removal decreases the risk of refracture.
  • Avoiding unnecessary disruption of the vascular supply to the bone decreases osteopenia. Furthermore, allowing sufficient time for the vascular supply to recover may correct the initial osteopenia.
  • Screw holes may remain as stress risers for as long as 4 months. 
  • Ankle Fracture:  75%  improvement after hardware removal (Jacobsen S,  Foot Ankle 1994; 15: 170-171).
  • Femoral IM nail: 65% Pain relief following femoral intramedullary nail removal (Dodenhoff RM,  J Bone Joint Surg Br 1997; 79: 738-741).
  • Tibial IM nail hardware removal:  45% rate of complete relief of knee pain after tibial nail removal; 35% of patients experienced partial relief and 20%, no relief. (Keating JF, J Orthop Trauma 1997; 11: 10-13)
  • No patient should be guaranteed complete pain relief.

Hardware Removal Associated Injuries / Differential Diagnosis

  • Nonunion
  • Malunion
  • Infection
  • Hematoma
  • Nerve injury

Hardware Removal Complications

  • Refracture
  • Continued pain

Hardware Removal Follow-up Care

  • There is no consensus concerning the necessary amount of protection, weight-bearing limits, or activity modification after implant removal.
  • Screw holes present a stess riser for up to 4 months after screw removal (Rosson J, Injury 1991; 22: 383-384).
  • Consider limiting impact and torsional loading for up to 4 months after hardware removal.
