The treatment of felons and paronychias.

Infections of the distal finger have a varied presentation, course, and treatment. As in other hand infections, initial treatment should always include elevation of the extremity and the avoidance of snug clothing or constricting jewelry. Immunosuppressive states and systemic diseases such as diabetes must be considered, for they will alter the action of the causative organisms as well as the intensity of treatment that a patient will require. Appropriate, specific antibiotic treatment can be part of the initial treatment of acute felons and paronychias, but it should never replace adequate incision and drainage. Finally, "minor" finger infections are only minor when diagnosed and treated properly. If mistreated, their consequences can have long-term implications for both the individual and for society. It is important to understand the natural history, bacteriology, and anatomy of the distal finger if we are to return patients to their jobs with expedience and minimal long-term sequelae.

Management of sea urchin spines in the hand.

The left palm of a 43-year-old woman was penetrated by sea urchin spines. Localization of the spines by soft tissue technique x-ray films proved to be the key to their easy removal. A review of the literature shows this to be an uncommon problem and that spine removal may be important to avoid long-term sequelae of pain and loss of function.

Management of the burned hand.

Current concepts in the management of acute and chronic injury to hands due to thermal burns are presented. A review of relevant functional anatomy and its alteration by the burn process is outlined. The maintenance of wrist extension, metacarpophalangeal flexion, and an open thumb web is critical in the acute phase. The physical therapist, using splints and regular exercise, is the key person in maintaining this position. The use of antibacterial agents, surgical debridement, and skin grafting is discussed. Surgical methods of reconstruction in chronic burns, the long-term role of the physical therapist, and the use of compression garments to minimize scar are stressed.

Common injuries of the fingernail and nail bed.

The most common injury to the dorsal distal finger is a subungual hematoma. Relief of pain is promptly achieved by draining the hematoma. If a heated paper clip is used, however, the underlying fluid may be seared and the hole plugged. Local anesthetic block followed by puncture with an 18-guage needle is advocated. When nail avulsion occurs, the free-floating proximal portion should be removed so that it will not serve as an irritant or hide any underlying pathology.

Volkmann's ischemic contracture due to soft tissue injury alone.

Fifteen upper extremities, in 14 patients in whom incipient or actual Volkmann's ischemic contracture was present, were seen in a 5 year period. Nine patients were stuporous due to drug overdose and had laid on the extremity; two had received a recent injury of main arterial trunks; two had sudden severe compression; one with chronic myelogenous leukemia had each arm involved at different times in a bizarre autoimmune response causing massive swelling. No patient had a fracture or dislocation. Pain and tenderness, loss of sensibility, resistant muscle contracture, and rock-hard muscle compartments were warning signs. Immediate fasciotomy was done. Useful function was restored when treatment was carried out in the early stages of the ischemia.

Post-traumatic trapped dislocations of the proximal interphalangeal joint.

This paper deals with the uncommon and frequently unrecognized problem of trapped dislocations of the proximal interphalangeal joint. These may be dorsal or volar. Soft tissue forming a noose, or interposed in the joint, is implicated. There is injury to one or more of the following structures: 1) extensor mechanism, 2) collateral ligament, 3) volar plate, 4) flexor tendon sheath, and 5) skin (compound dislocations). Open reduction and appropriate soft tissue repair are mandatory the essential features of diagnosis and management are discussed and four illustrative cases are presented.

Treatment of felons.

The pitfalls of traditional concepts in the management of a felon are reviewed. A more rational and uniformly successful method is detailed. This consists of a midvolar, longitudinal incision of the fat pad where the majority of abscesses point. Other incisions are reserved for the few cases in which maximal tenderness is shown elsewhere. An abscess should always be drained where it points. It has not been our intent in this report to discuss the problems of extension of infection beyond the closed space of the distal fat pad or to deal with paronychias and eponychias that simulate a felon by their extension.
