A treatise on orthopedic surgery . Advanced disease, showing wandering of tbe acetabulum and the obliquity ofthe pelvis due to adduction. Actual shortening one inch, apparent shorteningthree inches. the degree of final inequality depending upon the severity ofthe disease, the duration of the treatment, and upon the impair-ment of function. But even when free motion in the joint isretained, a certain degree of atrophy always persists and the lossin growth is never regained. If motion is completely lost the TUBERCULOUS DISEASE OF THE HIP-JOINT. 323 muscles about the joint lose in bulk in proportion to the disuseof their normal function; whereas the bones of the limb whichare still used to support the weight retain to a greater degreetheir normal size and length. Contrasted with this atrophythere is a relative hypertrophy of the sound limb, which isforced to assume more than its share of work. Actual Shoktenijstg.—^Actual shortening of the limb is aneffect rather than a diagnostic symptom of hip disease. Fig. Illustrating the destructive type of hip disease. The limb having been fixed inabduction. No displacement is present. The causes of actual shortening may be classified as: 1. Disuse of the limb. 2. The effect of the disease upon the epiphyseal cartilage ofthe head of the femur. 3. The more general destructive effects of the disease thatcause upward displacement of the femur. (a) Erosion of the head. (&) Erosion of the acetabulum. 324 OBTHOPEDIC SUBGEEY. (c) Depression of the neck of the femur. (d) Dislocation. Disuse, throughout a long i^eriocl of treatment, causes a cer-tain amount of shortening of the entire limb. To this theshortening of the bones of the leg and of the foot may be attrib-uted in great part. If the epiphyseal cartilage uniting theneck and the head of the femur is destroyed in whole or in partor if the disease hastens union at this point, a certain loss ofgrowth must follow. This is, of course, slight in degree, becausegrowth here is rela
