Direct and indirect trauma can cause injury to various portions of the pectoralis major muscle in varying degrees. Sprains and partial tears of the pectoralis major muscle are not uncommon. ⋯ Delayed diagnosis and delayed repair may prevent excellent results. A functional classification as presented here can aid in the diagnosis and treatment of these injuries.

Burns due to hot tar present a difficult management problem because the tar is difficult to remove without inflicting further injury to the underlying burn. We have found the surface active agent polyoxyethylene sorbitan (Tween 80, Sigma, St. Louis, MO) or Polysorbate (Sigma), by itself or in combination with an antibiotic ointment (neomycin sulfate) to be a safe and effective means of tar removal.
