Superficial infections include paronychia, cellulitis and lymphangitis. Grave infections include felon, purulent tenosynovitis, thenar infections, septic arthritis and human bites. Treatment by incision and drainage, moist heat, elevation, splinting and specific antibiotics or other agents applies to most hand infections. When pus is found, adequate drainage usually gives good results. Without drainage, pressure necrosis and gangrene often follow. Rest for the infected part and for the patient is as important as any other facet of treatment.
浅表感染包括甲沟炎、蜂窝织炎和淋巴管炎。严重感染包括脓性指头炎、化脓性腱鞘炎、鱼际间隙感染、化脓性关节炎和人咬伤。切开引流、湿热敷、抬高、夹板固定以及使用特定的抗生素或其他药物治疗适用于大多数手部感染。发现有脓液时，充分引流通常会取得良好效果。不进行引流，常随后发生压迫性坏死和坏疽。感染部位及患者的休息与治疗的其他任何方面同样重要。
