Acupuncture-related Digital Joint Infection Managed With Staged Surgery And Oral Antibiotic Therapy
Abstract
Acupuncture is generally considered safe; however, inadequate aseptic technique may result in infections involving the skin, soft tissue, bone, or joints. Gram-negative bacilli causing hand infections are uncommon and may present diagnostic and therapeutic challenges, particularly when multiple digits are involved. A 73-year-old woman developed progressive pain, swelling, and functional limitation of the right third and left fifth fingers approximately 1 month after acupuncture. Imaging suggested osteomyelitis with involvement of the interphalangeal joint. Separate sterile specimens were obtained from each affected digit before antibiotic initiation. Cultures identified Morganella morganii in the right third finger and Proteus mirabilis in the left fifth finger. Both isolates were susceptible to third-generation cephalosporins, beta-lactam/beta-lactamase inhibitor combinations, carbapenems, and fluoroquinolones, with low minimum inhibitory concentrations supporting levofloxacin use. A staged surgical approach was performed, consisting of initial debridement with placement of antibiotic-loaded bone cement, followed by delayed wound repair after infection control. Systemic antimicrobial therapy was guided by susceptibility testing, transitioning from intravenous ceftriaxone to oral therapy. At discharge, oral levofloxacin (750 mg once daily) was prescribed to complete an approximately 6-week treatment course. At 6-week follow-up, both wounds had completely epithelialized, with…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
