Reoperation after combat-related major lower extremity amputations.

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Reconstructive Surgery

Background:

• Complication rates and reoperation indications after trauma-related amputations are not well-defined.
• Combat-injured patients present unique challenges for amputation management.

Purpose of the Study:

• To identify and quantify the specific indications for reoperation following major lower extremity amputations in combat casualties.
• To analyze the impact of reoperation on patient outcomes.

Main Methods:

• Retrospective review of 300 major lower extremity amputations in combat-wounded personnel (2005-2009).
• Analysis of injury, treatment, complications, and revision data.
• Evaluation of pre- and post-revision outcomes, including ambulatory status and prosthesis use.

Main Results:

• A 53% reoperation rate was observed across 156 limbs at a mean follow-up of 23 months.
• Common indications for reoperation included wound infection (27%), symptomatic neuromas (11%), and heterotopic ossification (24%).
• Transtibial amputations had higher revision rates for neuromas, while knee disarticulations were less likely to require reoperation.

Conclusions:

• Reoperation for urgent surgical complications is frequent after combat amputations.
• Revision surgery for symptomatic residual limbs improves ambulatory status and decreases pain medication dependence.
