title: Partial or total calcanectomy as an alternative to below-the-knee amputation for limb salvage: a systematic review.
abstract: BACKGROUND
  Below-the-knee amputations are regarded as definitive treatment for calcaneal osteomyelitis. They may be less than desirable in patients with a viable midfoot and forefoot. Partial and total calcanectomies have been reported as an alternative for limb salvage. However, the durability of the residual limb is questionable.
  
  
  METHODS
  A systematic review was undertaken to identify material relating to the potential for limb salvage with partial or total calcanectomy in ambulatory patients with calcaneal osteomyelitis. Studies eligible for inclusion consecutively enrolled ambulatory patients older than 18 years who underwent partial or total calcanectomy without adjunctive free tissue transfer for the treatment of calcaneal osteomyelitis and had a mean follow-up of 12 months or longer.
  
  
  RESULTS
  Sixteen studies involving 100 patients (76 partial and 28 total calcanectomies) met all of the inclusion criteria. Weighted mean follow-up was 33 months. Minor complications with subsequent healing occurred in less than 24% of patients. Most major complications were related to residual soft-tissue infection and osteomyelitis. Approximately 10% of patients required a major lower-extremity amputation. Major complications and major lower-extremity amputations occurred more frequently after total calcanectomy and in patients with a diagnosis of diabetes. Eighty-five percent of patients maintained or improved their ambulatory status postoperatively. Only 3% of patients decreased their ambulatory status postoperatively, becoming unlimited household ambulators.
  
  
  CONCLUSIONS
  This systematic review provides evidence that partial or total calcanectomy is a viable option for limb salvage in ambulatory patients with calcaneal osteomyelitis.
