IX. Separation of Head of Radius.—Operationis required when the head of the radius has becomeseparated from the shaft and lies in the elbow-jointimpeding motion. Step I.—Make a three-inch longitudinal incisionas in Fig. 1143. Separate the anconeus and extensorcarpi ulnaris muscles. This exposes the head of radius. Step 2.—Incise the articular capsule. Remove thefragment of bone. Close the wound with deep andsuperficial sutures. Dress. Put in sling. Beginmotion very Fig. 1143.—Exposure ofhead of radius. CHAPTER LXX OSTEOMYELITIS As the result of infection acute inflammation develops in the vascular spongybone usually near an epiphysis. Pus quickly forms and, if the patient sur-vives long enough, makes its way to the periosteum and soft parts. Whenthe pus escapes, fistulae are formed and persist. Early death of portions oreven the whole of the bone is a prominent feature and aids in keeping up theinflammation. In time new bone is formed which incloses the dead portions(sequestra), keeps up the continuity of the bone, but prevents the escape ofthe sequestra when they become separated from the living bone by the activityof granulation tissue growth. From the above it is evident that different methods must be taken to combatthe disease according to the stage to which it has developed. When operatingfor osteomyelitis of one of the bones of an extremity, it is wise to secure abloodless field by using an elastic constric
