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 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.

Congenital radioulnar synostosis can be a disabling state, especially if it is bilateral or fixed hyperpronation. The purpose of this study is to introduce the surgical technique in proximal radioulnar synostosis who needs surgical intervention. Our procedures included excision of synostosis, interposition of muscle flap using brachioradialis, anconeus or extensor carpi ulnaris muscles with vascular pedicle for prevention of re-ankylosis and biceps transfer to improve supination. From July 1994 to July 1996, we evaluated 8 cases in 6 patients who underwent these procedures. The average age was 7 years and average duration of follow up was 24 months. The fixed forearms with hyperpronation have gained average 40 degrees of range of rotation. Improvement in holding and using small objects, sports activities and daily living activities was observed in all cases. There were no significant complications including re-ankylosis during the follow-up periods. In conclusion, surgical treatment of congenital radioulnar synostosis with these procedures is a reliable method that prevent re-ankylosis with providing forearm rotation.

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)

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.

We treated 74 fractures of the tibia by Interlocking intramedullary nail from Jan. 1982 to Mar. 1988. 58 of the fractures were fresh, 11 of these were open fractures. The other had 14 delayed union and nonunion and 2 ostetomy for malunion. Mean follow-up was 12.4 month and we analysed as follows: 1. Of 74 fractures, 73 fractures united and then the union rate was 98.5%. 2. Interlocking IM nail could be used to the majority of fractures of the shaft of tibia from 6cm below the knee joint to 5cm above the ankle joint. 3. Interlocking nail had rigid rotational stability and was appropriate for the treatment of severe unstable fractures. 4. Delayed union or nonunion was a good indication for intramedullary nsilling. 5. The major complication was deep infection. When the fixation was rigid with intramedullary nail, bone union was progressed in spite of infection. 6. Interlocking Intramedullary nailing provided rigid fixation of fracture and then it made possible early joint motion exereise and ambulation.

Synovial sarcoma is an uncommon, highly malignant soft tissue tumor usually arising from the synovial lining of a joint, bursa and tendon sheath. Occurence in muscle fascia is extremely rare. We present a case of synovial sarcoma of the left calf muscle fascia, which was confirmed by microscopically sarcomatous growth of spindle cells and irregular small multiloculation. Above knee amputation was done.

Purpose: The purpose of this paper is to clinically evaluate the usefulness of all arthroscopic repair with biceps incorporation in massive sized full thickness rotator cuff tears. Materials and Methods: This is a prospective comparative outcome study evaluating a series of all arthroscopic rotator cuff repairs with biceps incorporation on massive (range: 5~6 cm sized) from March 2003 to May 2006. Group I was twenty two cases of arthroscopically repaired with biceps incorporation, twenty cases of group II without biceps incorporation were analyzed. The average age of the patients was 58 years (range, 41~74 years), and mean follow-up was 24 months (range, 12~36 months). Results were statistically compared by Mann-Whitney test. Results: Average VAS for pain, ADL, UCLA score were not significantly different between group I and group II (P>0.05 for each). Forward elevation strength was 4.3 in group I, 3.5 in group II (P<0.05). On postoperative follow up ultrasound, retear was 10 cases in the middle of 19 cases at group I, 15 cases in the middle of 17 cases at group II (P<0.05). Conclusion: This study reveals that all arthroscopic repairs with biceps incorporation in massive sized full thickness rotator cuff tears is an effective surgical method and reduced retear and enhanced strength.
