Patella Chondromalacia / 대한정형외과학회잡지

Early chondromalacia patellae is initiated by malalignment in the extensor machaniam and abno-rmal patellofemoral tracking. It is well known that chondromalacia often occurs in recurrent pateIlar subluxation. In the 50 normal and 60 pathologic knees, the following five parameters were studied; 1) Q angle 2) PT ratio by Insall & Salvati method 3) AB ratio dy Blackburne & Peel method 4) sulcus angle 5) congruence angle. The following conclusions were made. l. In 50 normal asymptomatic knees, the average Q angle was 14°. The patellar length was equal to the patellar ligament length and the average congruence angle was −8°. In 40 knees with “Chondromalacia”, the Q angle was increaed (19.5°), and the average congruence angle was −2°. 3. In 20 knees with recurrent subaxation, the patellar was high riding (PT ratio, 0.89), the sulcus angle was shallow (145.1°), and the average congruence angle was +4.35°.

Clear Cell Chondrosarcoma: 1 Case Report / 대한정형외과학회잡지

Clear cell chondrosarcoma is thought a varient of chondrosarcoma. The tumor usually involves the proximal part of the femur or humerus. Histologically, tumor cells with abdundant clear cytoplasm and benign giant cells are usually found. En bloc resection rather than more radical surgery is thought adequate in the treatment, We have experienced one case of clear cell chondrosarcoma affecting the calcaneus, which is reported in this paper with brief review of literature.

Replantation of Hand Amputated Through the Palmar Arch Level / 대한정형외과학회잡지

The value of replantation of parts of the upper limb is well established and replantation of a digit has now be come a standard procedure. However, there are few reports of replantation of hand amputated through the palmar arch level. We have reviewed 14 cases of 14 patients replantation of hand amputated through the arterial palmar arch level from Mar. 1976 through Mar. 1982. The success rate in our series is 64 percent. This is slightly lower than the other levels due to its anatomical complexity. According to the anatomical complexity and distribution of nerves and vessels, it is divided to three levels. In level A, the superficial palmar arch and/or the deep palmar arch should be repaired. In level B, the princeps pollicis artery should be repaired after anastomosis of the superficial and deep palmar arch. In level C, each common palmar digital artery should be repaired but if it is impossible to repair of all fingers, replantation of thumb and index should be performed as possible. Meticulous microsurgical technique and precise anatomical knowledge is mandatory for replantation of the palmar arch level.

Histological Changes Induced by Neurolysis: An Experimental Study on Rabbit Sciatic Nerve / 대한정형외과학회잡지

Several attempts have been made to assess the relative importance of the vasa nervorum and the intrinsic longitudinal vascular plexuses of nerve in maintaining the blood supply of a segment of nerve trunk, but the effect of mobilization on the ability of an injuried or repaired nerve to regenerate and regain function has been less certain and is the subject of these investigations. Thirty-two Korean rabbits of both sexes were used for these studies and we concluded that it is increased fibrosis with adhesion to surrounded tissues, loss of glistening and milk-like discoloration of never grossly, and increased degeneration and milk-like discoloration of nerve grossly, and increased degeneration of axons and demyelization progressively and early proliferated Schwann cells with increasing length of neurolysis. And there was no recovery of damage in nerve tissue induced by above 7 cm of neurolysis. (1:35)
