Anatomic relationships of flexor sheaths to deep fasical spaces should be kept in mind. Contiguous spread can result in a “horseshoe abscess”: from small finger flexor sheath to the thumb flexor sheath via connection between the radial and ulnar bursae. Management Patients suspected of having a hand infection will often undergo plain x-rays. The bony structures will typically appear normal except in very advanced infections involving the bone. Ultrasound can show loculated fluid collections, but is heavily dependent on the skill of the person performing the study. Magnetic resonance imaging, with or without gadolinium contrast, may show occult deep space infections if the clinical picture is not clear. Use of MRI is limited by cost as well as availability depending on when and where the patient is being evaluated.

Loss of function, loss of sensation, disfigurement, or even loss of the finger is possible. Coagulopathy Don't try to puncture or cut into an abscess yourself. Doing that can lead to a more serious infection or other complications. The doctor may need to drain the abscess and possibly prescribe antibiotic medications to treat the infection. Once an abscess is treated, the finger or toe almost always heals very quickly. After your initial soak, cut the hangnail off. Eliminating the rough edge of the hangnail might reduce further infection. Make sure to cut it straight with cuticle clippers. Early recognition and proper treatment of the following main finger infections will help prevent most of the serious outcomes.

Coexisting problems such as diabetes or blood vessel disorders of the arms and legs will complicate the infection and may change the degree of treatment.  How to Spot and Treat Cellulitis Before It Becomes a Problem Featured Teens site Flexed posture of the digit. EM Zen Related Content Paronychia (pronounced: pair-uh-NIK-ee-uh) is an infection of the skin around a fingernail or toenail. The infected area can get swollen, red, and painful. Sometimes a pus-filled blister may form. The diagnosis of acute paronychia is based on a history of minor trauma and findings on physical examination of nail folds. The digital pressure test may be helpful in the early stages of infection when there is doubt about the presence or extent of an abscess.14 The test is performed by having the patient oppose the thumb and affected finger, thereby applying light pressure to the distal volar aspect of the affected digit. The increase in pressure within the nail fold (particularly in the abscess cavity) causes blanching of the overlying skin and clear demarcation of the abscess. In patients with severe infection or abscess, a specimen should be obtained to identify the responsible pathogen and to rule out methicillin-resistant S. aureus (MRSA) infection.13 barrier damage to the nail folds, cuticle (chronic) MS and Depression: How Are They Linked?

If a collection of pus is present, it will need to be drained. This may be done in several different ways. Commonly a scalpel is used to make a simple incision over the collection of pus to allow drainage. Or the scalpel may be inserted along the edge of the nail to allow drainage. If the infection is large, a part of the nail may be removed. If this procedure is required, the doctor will inject a local anesthetic at the base of the finger that will provide for a pain-free procedure. Most often, you will be placed on an oral antibiotic. You will then be instructed how to take care of the wound at home. (See paronychia.) Allergies Can a Warm Soak With Epsom Salt Really Help Your Skin?
