Brief summary
Persistent residual limb pain is common after traumatic amputation and significantly impairs rehabilitation and prosthetic use. Postoperative stump infection may contribute to peripheral nerve sensitization, scar fibrosis, and long-term pain persistence. This prospective cohort study aims to determine whether early post-amputation stump infection independently predicts persistent clinically significant residual limb pain at 3 and 6 months after surgery.
Detailed description
Patients undergoing traumatic limb amputation will be enrolled within 4 weeks after surgery and followed for 6 months. Early postoperative stump infection will be recorded using predefined clinical criteria. Pain intensity (Numeric Rating Scale), neuropathic pain screening (DN4), and phantom limb pain will be assessed at baseline, 3 months, and 6 months. Multivariable logistic regression will be used to evaluate whether stump infection is independently associated with persistent residual limb pain, adjusting for amputation level, injury mechanism, revision surgeries, antibiotic exposure, and demographic factors.
