Contact Dermatitis in Surgeons from Methylmethacrylate Bone Cement

BY IAN BLAIR FRIES, M.D.*,ALEXANDER A.FISHER, M.D., AND EDUARDO A.SALVATI, M.D.*, NEW YORK, N.Y.

From the Hospital for Special Surgery Affiliated with the New York Hospital- Cornell University Medical College, New York City

In 1956, Fisher identified methylmethacrylate monomer as the cause of allergic dermatitis in four dentists and dental laboratory technicians who had come in repeated contact with acrylic denture materials, and this was also reported in one orthopaedic surgeon handling bone cement2. Methylmethacrylate monomer does diffuse through intact surgical rubber gloves2. An allergic eruption on the hands of one of the authors (I.B.F.) stimulated us to investigate the allergenic effects of bone cement.

Case Report

In 1972, I.B.F. frequently participated as assistant surgeon in cases of total joint replacements. Often this required that he mix and handle methylmethacrylate cement. Routinely the operation was done with two pain of gloves, the outer pair being chanced frequently. Often it was changed just prior to handling the cement.

A mild pruritis in the fingers first developed the night following operations, but no treatment was sought. Some paresthesias also developed which were attributed to over-tight gloves. However, larger gloves did not alleviate the symptoms.

At the end of 1972, he performed two joint-replacement procedures. Following the first he experienced pruritis, swelling, and erythema of the right and left index fingers and the right long finger. This subsided spontaneously in a few days. After the second operation, a week later, the same symptoms reappeared, this time associated with a localized vesicular eruption. Overnight incapacitating deep tenderness developed in these fingers, making it impossible for him to operate for three weeks.

Extensive patch tests were performed with a number of suspected contactants, but the only positive patch test was to methylmethacrylate monomer.

The dermatitis was successfully treated with topical steroid ointment. The skin of the affected fingers remained atrophic and scaling for about three weeks, and deep tenderness and parethesias lasted for about two months. After this episode, recurrence of the dermatitis was prevented by avoiding contact with bone cement, that is, the cement was handled by other members of the surgical team.

We collected thirteen cases of dermatitis in handlers of bone cement, including nine in active orthopaedic surgeons. Of these, seven demonstrated patch-test sensitivity to methylmethacrylate monomer (10 per cent in olive oil). We consider these seven to be cases of true allergic contact dermatitis characterized by itching, erythema, edema, and vesiculation followed by eczematization (Fig. 1). Three of

the subjects showed complete resolution of their eruption with careful avoidance of the monomer, but did not demonstrate a positive patch test. We do not consider their reactions to be allergic. The dermatitis was marked by the presence of dryness and fissuring of the finger tips, but without pruritis and vesicle formation. Three of the patients were identified through correspondence and have not yet been fully characterized as allergic.

The observations of Pegum and Medhurst led us to examine different types of surgical gloves in the hope of finding one that would successfully isolate the surgeon’s hands from the monomer. Glove fingers were cut off intact gloves and filled with small amounts of powdered polymer. The tips of these filled glove fingers were immersed in glass vials containing monomer. A test period of twenty minutes was chosen as the maximum time a surgeon might be in cedure. After twenty minutes the filled glove fingers were removed from the monomer and the contents were excontact with the bone cement during any one operative proamined. In all cases partial to complete polymerization of the powdered polymethylmethacrylate was noted, indicating that monomer had diffused directly through the gloves.

The majority of the gloves also showed evidence of direct attack by the monomer. One type of glove completely disintegrated. The vinyl glove tips were markedly affected, and most latex rubber gloves showed wrinkling and brittleness. In many of the trials the monomer solution was discolored by leaching of dye from the gloves. In approximately one-third of the samples the polymerized cement also took on coloration from contact with the gloves (Table I).

The unique and consistent feature of the dermatitis from bone cement was paresthesia. Deep tenderness was also common and outlasted the duration of the eruption.

Methylmethacrylate monomer is a lipid solvent. The irritant effect of the monomer is probably due to its ability to degrease the skin and penetrate the subcutaneous tissue. Apparently some surgeons with a mild sensitivity are able to avoid the dermatitis by using three layers of gloves during handling of the cement, and then immediately removing the outer two, or possibly all three gloves. Multiple gloves tend

to retard and reduce diffusion, proportionally to the number of layers. However, diffusion is not prevented and the monomer tends to be kept in contact with the skin. Merely painting methylmethacrylate monomer on the skin of a sensitive subject has been shown not to cause an allergic reaction because the monomer evaporates so rapidly. However, if the monomer is applied under an exclusive or semiocclusive dressing, a reaction will ensue in the sensitive subject. Synthetic gloves are currently under development that we hope will be impervious to methylmethacrylate monomer.

People are increasingly concerned about potential environmental health hazards and often ask their physicians questions such as: "Is the tap water safe to drink?" "Is it safe to live near power lines?" Unfortunately, physicians often lack the information and training related to environmental health risks needed to answer such questions. This book discusses six competency based learning objectives for all medical school students, discusses the relevance of environmental health to specific courses and clerkships, and demonstrates how to integrate environmental health into the curriculum through published case studies, some of which are included in one of the book's three appendices. Also included is a guide on where to obtain additional information for treatment, referral, and follow-up for diseases with possible environmental and/or occupational origins.
