Diagnostic and Management of Hand Infection: a Retrospective Cohort in a Tertiary Care Center.

Primary or secondary (post-traumatic infections, notably related to bites, wounds, etc.) infections of the hand are very common situations, even if the epidemiology is poorly understood. For example, hand bite injuries represent 1.2 million referrals to the healthcare system per year in the United States. Their nosological framework extends from simple infections of the skin and soft tissues such as whitlows, to potentially severe deep damage such as arthritis and osteitis, or phlegmons of the tendon sheaths. The diagnostic approach is not consensual, and the contribution of additional biological parameters (inflammatory syndrome) and morphological investigations (x-rays, ultrasound, CT-scan or MRI) is not codified. Microbiology seems dominated by Staphylococcus aureus, but few studies have precisely described the microbial etiology. Consequently, probabilistic antibiotic therapy and the need to take bacteriological samples for secondary adaptation are not standardized. Likewise, surgical strategies (abstention, systematic washing or depending on evolution) remain operator dependent. We consequently aim to described diagnostic, management and related outcomes or hand infections in a specialized tertiary care center.
