The intravenous fluorescein test: use in timing of groin flap division.

Successful division or delay of the arterial groin flap requires an accurate prediction of viability. The fluorescein dye test is an objective test to determine the earliest possible time a pedicle can be divided. It is an easy, quick, and comfortable test that can be repeated many times without injuring or altering the flap. It consists of an intravenous injection of fluorescein while the pedicle is temporarily and reversibly occluded. All areas with adequate revascularization fluoresce under ultraviolet light. In three groin flaps intended for hand resurfacing, interval fluorescence testing was the sole criterion for successful pedicle division. In an experimental neurovascular island skin flap in the rat, the validity of the fluorescein test was confirmed. In the clinical situation and in the experimental model, fluorescence is an accurate indicator of groin flap revascularization and a predictor for the timing of safe and early groin flap division.

Experimental work with isoxuprine for prevention of skin flap necrosis and for treatment of the failing flap.

The administration of isoxuprine intraperitoneally resulted in the complete survival of abdominal island skin flaps in rats that otherwise underwent a standard pattern of necrosis. The drug was effective when administered for two weeks before and one week after raising the flap, or when administered afterwards alone. The mechanisms of its action were investigated and are described.

Hand injuries: incidence and epidemiology in an emergency service.

During a four-month period, 1,164 patients presented to the surgical section of our Emergency Services (ES) with chief complaints involving the hand. Patient records were analyzed for several variables including demographics, diagnosis and therapeutic procedures. Lacerations were the most frequent injury, 61.5% (n=716) with deep structure injuries present in 6.1% (n=44). Of deep structure injuries, 36.4% were tendon lacerations, 27.2% were nerve injuries, and 36.4% were compound fractures. "Bites" accounted for 5.2% (37) of all lacerations, eight of which were human bites. Fractures were the second most frequent injury, (11.4%) and involved 143 separate bones. Infections were present in 7%; over half were paronychias. There were 42 (3.6%) thermal injuries.

An experimental neurovascular island skin flap for the study of the delay phenomenon.

We present an experimental neurovascular island skin flap. It is a consistent, reproducible model which produces a definite pattern of surviving skin flap area versus skin flap necrosis. There is a constant, anatomically definable nerve and vascular supply to the flap. This model permits independent experimental manipulation of the neural, arterial, and venous supply to the skin. It is useful, therefore, for the study of the vascular mechanisms of the skin microcirculation. We also demonstrated that increased flap survival can be produced by a delay involving denervation alone (leaving the vascular supply intact) or by devascularization alone (leaving the nerve supply intact). We conclude that both the adrenergic denervation and the ischemia contribute to the production of the delay phenomenon. We suggest that sustained vasodilation--vascular smooth muscle relaxation--is the vascular mechanism that accounts for the delay phenomenon.

Nicotine and its effect on wound healing.

Our data demonstrate that nicotine impairs wound contraction in the rabbit ear model from the 4th to the 10th day of wound healing. However, the wounds contracted at essentially the same rate from the 12th to the 20th day in the experimental and control groups of animals. This study would suggest that cigarette smoking, with its associated nicotine ingestion, is adverse for a time to wound healing. It is clearly possible that in cases of extremity injury, or surgery, cigarette smoking may adversely affect wound healing.

Prevention of skin flap necrosis by a course of treatment with vasodilator drugs.

Large island skin flaps, comprising the entire abdominal covering in rats, were raised on one neurovascular pedicle in the groin. A standard area of necrosis was produced on the other side from the pedicle. However, when the animals were treated with certain vasodilator drugs for 15 days before and 7 days after the flaps were raised, there was little or no necrosis. The effect of the drug therapy was the same as a surgical delay.

Epidermolysis bullosa: current concepts and management of the advanced hand deformity.

A current classification of the types of epidermolysis bullosa is reviewed, in conjunction with some etiological concepts. The pathomechanics of the advanced hand deformity are discussed, and applied to a sequential plan of reconstructive surgery. The objective is the restoration of elementary hand function. Two illustrative cases are presented.

Cigarette smoking: impairment of digital blood flow and wound healing in the hand.

Smoking a single cigarette can reduce digital blood flow. Sarin (1974) showed a 42% reduction in digital blood flow in his series, and other investigators have shown similar findings (Ludbrook 1974, Rottenstein 1960). The focus of this paper is on the pharmacological effects of the various components of cigarette smoke and their potentials effects on wound healing in the hand. A case is described to illustrate the effect of stopping smoking upon a non-healing fingertip ulcer.

Use of intramedullary polypropylene peg for joint stabilization in leprosy.

Joint arthrodesis is indicated when motion in a joint cannot be restored, and that joint requires stabilization in an optimal functional position. The Harrision Intramedullary peg has been used to advantage for this purpose in hand reconstruction in leprosy in a renal developing area. It is a method to be considered for selected cases requiring joint stabilization to improve total hand function.

Nerve grafting in the repair of complicated peripheral nerve trauma.

Peripheral nerve trauma has been a challenge to surgeons, with significant advances in the surgery of repair occurring in major wars. The standard method of treatment involving wide mobilization and end-to-end suture to close traumatic gaps in peripheral nerves has not produced consistently acceptable results, particularly with large gaps. However, with the recent development of microsurgical techniques and instrumentation, the method of interfascicular nerve grafting has been applied to selected patients with trauma problems of the peripheral nerve, by resecting and autogenous nerve grafting at staggered levels to distribute scar formation, followed by plaster immobilization for 3 weeks. Ten patients are reported, with motor nerve recovery ranging from M2 to M4 and sensory recovery, S2-S4 (See Table I), based on Seddon's classification (11).

Plastic surgery in rural Ethiopia.

From this brief experience in Ethiopia I believe that plastic and reconstructive surgery can contribute much to the lives of many people in such underdeveloped regions of the world. If one will teach the principles of plastic surgery to the general surgeons and paramedical people who do most of the work in these areas, it can amplify and expand their capabilities. Surgery is, of course, only one link in the long chain of basic health issues, and the ultimate solutions are on a different level. Yet, the magnitude of the problems is a compelling reason to make the effort, to take the time, and to contribute our skills in developing regions of the world. Though we cannot alone conquer the entire problem, we can do our bit.
