Soft tissue related complications are quite frequent in limb lengthening. Muscle fibers may proliferate or regenerate after stretching injury over 10-20% of their original length. However, the cells which are engaged in this phenomenon are not confirmed yet. We chased the S-phase cells (phase for DNA replication) in the posterior leg muscle during limb lengthening by immunohistochemical technique. We lengthened the tibiae of fifteen New Zealand white rabbits. We divided them into three groups and each group is consisted of five rabbits. In group 1, we lengthened the left tibiae by 10% of their original length, in Group 2, 20%, and in group, 3, 25%, respectively, At the end of lengthening posterior muscles of lengthened left side and of controlled right side were fixed and processed for Immunohistochemical staining which could detect the incorporation of bromodeoxyuridine(BDU). Labelling index(LI:% of positively stained S-phase nuclei) of group 1 was zero. LI of groups for more than 20% lengthening (sum of group 2 and 3) was statistically significant. In conclusion, nuclei around or within the muscle tissue are in S-phase during limb lengthening which means proliferation of the muscle fivers or of the certain cells that abut muscle fibers.

This study consisted of 66 peritrochanteric fractures which were treated by the modified Gamma nail (Asian Pacific nail) from August 1993 to October 1995. Sixty-one intertrochanteric fractures and five subtrochanteric fractures were treated in our institution. Average length of follow-up was 15.0 months. Four patients died during follow-up. The results were as follows; Lag screws were ideally introduced in 55 (83%) cases. The mean length in lag screw sliding was 4.3 mm in stable trochanteric fractures and 5.7 mm in unstable ones. Fifty-one out of 62 patients (82%) were returned to their previous ambulatory status. Intraoperative complications were as follows; distal crack (3 cases); rotation of femoral head (2 cases); entry point crack (I case); medialization of proximal fragment (7 cases); and missing of the interlocking screw (1 case). All of these complications did not affect the outcome. All medial cortical gaps were closed after sliding of lag screws. Three distal cracks did not propagate to the shaft. Postoperative complications were a case of superior cut-out, and two second fractures after falls. Callus formed more early in the stable trochanteric fractures (5+/-2.1 weeks) than unstable fractures (7.3+/-2.1 weeks). It was statistically significant. Union time between stable and unstable trochanteric fractures was not statistically significant. In conclusion, the Asian Pacific (AP) nail could appropriately fix the osteoporotic peritrochanteric fractures in elderly patient. It could offer early rehabilitation to these patients and decrease the mortality and morbidity.

Ilizarov technique has been successfully applied to limb lengthening for several decade, one of its main drawback is, however, long application of external fixator over 6 months. To lessen this time, simultaneous intramedullary fixation which convert later to static fixation by insertion of interlocking screws has been proposed. The indication for surgical limb lengthening includes familial short stature below the 3rd percentile. We compared the results of thirteen tibial lengthening with Ilizarov method to that of eleven hybrid methods. The hybrid system is composed of an unreamed AO intramedullary nail (IM) and ring fixator. Once the lengthening is completed, distal interlocking screws were inserted. In the group who were treated by hybrid system, the mean lengthening of tibia was 7.1cm (range, 6.3-9.5), the mean of external fixation period 7 months (range, 5-9), the mean healing index 1.2 month/cm (range, 1.1-1.4). On the other hand, the mean lengthening of tibia was 7.5cm (range, 5-10.3), the mean of external fixation period 9.8 months (range, 6-15), the mean healing index 1.4 month/cm (range, 1.1-1.8) in the group treated by Ilizarov method. Mean follow-up period was 23 months (range 14-47). There was no rotational or angular deformities and no loss of lengthening in the hybrid group. However we experienced three cases of angular deformity at the distraction site during lengthening in Ilizarov group. There was no deep infection in both groups. In the hybrid group we found several advantages such as no deformity, no loss of lengthening, and less scar by early removal of fixator, but some disadvantages such as need of subsequent procedures and limitation in intramedullary nailing.

Of the many theoretical causes of rheumatoid arthritis(RA), the most widely held theory is the autoimmune mechanism. In order to clarify the clinical significance of the immunological tests in RA, we studied immunoglobulin and complement levels in sera and synovial fluids of 118 RA patients and the following results were obtained. 1) The levels of immunoglobulins were elevated in both serum and synovial fluid and this was more prominent in the seropositive cases than the seronegative ones. 2) The levels of C3 component were decreased in both serum and synovial fluid, while those of C4 were decreased only in synovial fluid. Serum C3 and C4 component levels were more decreased in the seropositive cases than the seronegative ones. 3) The immunoglobulin levels in serum (IgG, IgM and IgA) and synovial fluid (IgG and IgA) and the levels of C3, C4 component in serum were well correlated with the clinical forms of rheumatoid arthritis. 4) The IgA level in serum and IgM level in synovial fluid were more increased in the exacerbated cases than the chronic ones. 5) Serum IgG level was decreased after steroid medication over one month.

PURPOSE: The purpose of this study was to evaluate early outcomes of ALTA (aluminum potassium sulfate and tannic acid, Ziohn(R)) injection compared with those of a submucosal hemorrhoidectomy for the treatment of internal hemorrhoids. METHODS: From September 2008 to April 2009, a total of 50 patients who had internal hemorrhoids (Golliger grade II to IV) were treated by using either ALTA injection (n=25) or a submucosal hemorrhoidectomy (n=25). Outcomes with respect to pain scores, analgesics use, and satisfaction levels of the patients, and complications were compared. RESULTS: The mean number of hemorrhoidal piles was 3.52 in the ALTA injection group and 3.56 in the operation group. The average amount of ALTA injection was 27.34 cc. Pain scores measured at one day and 7 days after the treatment, and the number of analgesics used in the injection group were significantly lower than those in the operation group (P<0.001). However, there was no significant difference in the satisfaction level between two groups. One case of treatment failure was found in the ALTA injection group. There was no difference in complications between the injection group (n=4) and the operation group (n=5) (P=0.725). CONCLUSION: When compared with a submucosal hemorrhoidectomy, ALTA injection showed less post-treatment pain and less analgesics use. Overall complication rates were not different between the two groups. We found the early outcomes of ALTA injection for the treatment of internal hemorrhoids to be comparable to those of surgery. Thus, large-scale and long-term follow-up studies are needed to clarify the proper indications for ALTA injection.
