Elective HardwareElective Hardware
Harrington Rods are common
Need to evaluate the fusion mass
Broken rods happen a lot, often not clinically significant

Broken HardwareBroken HardwareCommon source of patient complaint
Need to figure out underlying reason
infection
instability of fracture
insufficient hardware strength
Does it compromise the fracture mechanically?
Most broken hardware is not medically necessary to remove!!

Always have to be alert for this
Source of a lot of litigation
Need to do the complete workup and clinical evaluation
Need to handle the situation in accordance with accepted standards

Infected Hardware WorkupInfected Hardware Workup
Xrays
Evaluate for loosening or breakage
Tests include CBC, Sed rate, C-reactive protein
If infected, all hardware must come out in infection zone in order to treat infection
Some infections are tolerated as chronic

Incidental HardwareIncidental Hardware
Common to have shrapnel left in
Removing shrapnel usually does more damage than leaving it
Pain often not resolved by removing shrapnel because of blast injury
Only reason to consider removal is infection or obvious dysfunction
![Page 29: Orthopedic Hardware Problems. Todd R. Wilcox, MD, MBA, CCHP-A Medical Director Salt Lake County Jail System trwilcox@wellcon.net 801-990-3440](https://reader033.vdocuments.mx/reader033/viewer/2022051401/56649f165503460f94c2ca7e/html5/thumbnails/29.jpg)
Painful HardwarePainful Hardware
Most orthopedic hardware is painful
Pain typically relieved with NSAIDS
Occasionally narcotics are indicated
Significant increase in pain needs workup to evaluate for infection
Removal of hardware frequently helps but is not medically necessary

Only if fracture has not healed and is not infected
Historical fractures or retained hardware is not a legitimate justification
