Area of Science:

  • Orthopedics
  • Infectious Diseases
  • Dermatology

Background:

  • Osteomyelitis is a bone infection that can affect any bone, including the phalanges of the hand.
  • Phalangeal osteomyelitis, particularly in the thumb, is uncommon but can arise from contiguous spread of infection.
  • Nail biting is a common habit that can compromise the integrity of the skin around the nails, creating an entry point for pathogens.

Observation:

  • A 39-year-old male presented with symptoms indicative of infection in the right thumb phalanx.
  • The patient had a history of habitual nail biting.
  • Clinical examination revealed signs of localized infection in the thumb.

Findings:

  • Microbiological cultures from the affected site identified Staphylococcus aureus as the causative agent.
  • The patient was treated with intravenous teicoplanin at a dosage of 400 mg daily for three weeks.
  • Radiological and clinical assessments confirmed the complete resolution of the osteomyelitis.

Implications:

  • This case highlights nail biting as a potential risk factor for developing phalangeal osteomyelitis.
  • Staphylococcus aureus is a common pathogen in osteomyelitis, necessitating appropriate antibiotic selection.
  • Prompt diagnosis and treatment with effective antibiotics like teicoplanin can lead to favorable outcomes in phalangeal osteomyelitis.
