Removal of Painful Tibial Intramedullary Nail Hardware
For a painful tibial intramedullary nail placed years ago with solid bony union, you should remove only the interlocking screws first rather than the entire nail, as complete nail removal has poor outcomes for pain relief and carries significant risks of complications.
Clinical Decision Algorithm
Step 1: Confirm the Indication for Hardware Removal
The primary question is whether pain justification alone warrants any hardware removal. The evidence shows:
- Anterior knee pain after tibial nailing is extremely common (23% of all cases) and persists in the majority even after complete nail removal 1
- Only 55% of patients (39/71) experienced pain reduction after complete nail removal, while 25% had unchanged pain and 25% had worse pain after removal 2
- New anterior knee pain developed in patients who were previously asymptomatic after nail removal 3
Step 2: If Removal is Pursued, Start with Screw-Only Removal
The preferred approach is isolated screw removal because:
- Screw removal for pain/discomfort is the most common subsequent surgery (9% of all tibial nail cases) 1
- This is a lower-risk procedure compared to complete nail extraction
- It addresses hardware prominence and local irritation without the major risks of nail removal
Step 3: Reserve Complete Nail Removal for Specific Indications Only
Complete nail removal should be performed ONLY for:
- Active infection 4
- Nonunion requiring revision fixation 4
- Deformity requiring correction 4
- Refracture requiring new fixation 4
Pain alone is NOT a convincing indication for complete nail removal 2.
Critical Pitfalls and Complications
Risks of Complete Nail Removal:
- Bone overgrowth/ingrowth can make extraction extremely difficult or impossible, requiring major procedures including longitudinal bone windows removing one-third of the tibial circumference 4
- Fracture during extraction can occur, particularly if distal screws aren't removed first 3
- Most patients require crutches for ambulation post-removal and average 11 days of sick leave 3
- The procedure may need to be abandoned if the nail is incarcerated 3, 4
Patient Counseling Requirements:
Before any removal procedure, patients must understand:
- Pain may persist unchanged (20% of cases) 2
- Pain may worsen (25% of cases) 2
- New knee pain may develop even if currently asymptomatic 3
- Crutches will likely be needed for 2+ weeks 3
- Extraction may require extensive bone windows and prolonged recovery if the nail is stuck 4
Why This Approach?
The evidence consistently demonstrates that pain relief from tibial nail removal is unpredictable and often disappointing 2, 3. The 2020 systematic review of 8,110 patients confirms anterior knee pain is the most common complication (23%) and that screw removal is the most frequent subsequent surgery 1.
Starting with screw-only removal provides a lower-risk intervention that addresses hardware prominence while avoiding the substantial complications of complete nail extraction. The 2007 study's conclusion is unequivocal: "The results of nail removal to alleviate pain are poor. Removal of a nail should not be undertaken unless there is a convincing indication" 2.
If screw removal fails to provide adequate relief and pain significantly impacts quality of life, only then consider complete nail removal—but with extensive informed consent about the high likelihood of persistent or worsened symptoms.
