The immcfliatcresults are those of painful disability; the ultimateresult is impaired function. That the end-resultsare bad is perhaps not generally realized. Cottonhas stated that go per cent of those who sustainthis fracture are thereby more or less permanentl>disabled. This same observer with Henderson hasreported the end-results in seventy-five cases andconcludes the following: Conservative treat-ment gives incredibly bad results. We must dobetter than this—it must be possible. Magnusonhas estimated the ultimate loss of function afterOS calcis fracture as from 35 to 75 per cent, basingthis finding on the reports of the Illinois Indus-trial Accident TuK Types of Os Calcis Fracture and TheirClinical Significance Conn has recently classified the various types ofOS calcis fracture under five heads: Type one. Impacted fracture producing ever-sion of the os calcis with mesial deflection of theweight bearing line, and without fracture into thesubastragalar joint. Type two. Comminuted fracture with upwarddisplacement of the distal fragment, so that theposterior portion of the os calcis is pulled upwardiDy the tendo Achillis, without fracture into thesubastragalar joint. Type three. Impacted comminuted fracture re-sulting in shortening and thickening of t;e oscalcis, so that a displaced bone mass impinges onthe external malleolus, without fracture into thesubastragalar joint. Type four. Multiple fracture lines, some ofwhich transverse the sustentaculum tali andwhich enter the subastragalar articulation. Type five. Extensive comminution of the boneanterior to the sustentaculum tali with multiplefracture into the subastragalar j
