Saunders, 1997. $55.00, 283 pp. JF The Journal of Bone & Joint Surgery JO The Journal of Bone & Joint Surgery YR 1998 FD February 1 VO 80 IS 2 SP 307 OP a DO UL http://dx.doi.org/ AB We are living in an era in which the financiers of managed health care deny the need for specialization, much less subspecialization, in medicine. What we are told, essentially, is that the expansion of medical science and knowledge is no longer cost-effective. This period in medicine may well be similar to the Dark Ages, when too much knowledge was considered dangerous. This book reflects the belief that only a specialist would be knowledgeable about the syndromes, illnesses, and injuries affecting runners as well as about the quirks and eccentricities involved in caring for the special needs of these patients. To know less would mean that one accepts care that is less than optimum.
