Pretwisting the patellar tendon graft has been advocated hy many authors. Lambert has described a 90 degrees pretwist to benifit the fat pad vascular supply as well as to "" simulate the helicoid course of the ACL "". This technique has also been recommended to fascilitate fixation. Jackson has recommended a 90 pretwist to decrease the possibility of abrasive wear on the tunnel edge, and also to fascilitate fixation as much as a 180 degrees pretwist has heen recommended. However, in spite of all these recommendations, little work has been done on the effect of such pretwisting on the biomechanical behavior of patellar tendon grafts. The purpose of this study is to discover, by experiment, the effects of a 360 degrees external rotation pretwist on the following tensile mechanical properties of canine central 1/3 patellapatellar tendon-tibia complex : (a) ultimate stress, (b) ultimate strain, (c) average elastic modulus, and (d) strain energy density. Five groups of each S specimens were divided as group 1 (0 degrees external rotation), group 2 (90 degrees external rotation). group 3 (180 degrees external rotation), group 4 (270 degreesexternal rotation), and group 5 (360 degrees external rotation). The direction of pretwist meant the twist of tibia around patella. The effects of pretwist were analyzed using parameter one-way analysis of variance (ANOVA)(P1) and nonparameter Kruskal-Wallis one-way analysis of variance (ANOVA)(P2) with repeated measures followed by Scheff multiple comparison test. A p values of < 0.05 was considered statistically significant. Among each groups ultimate stress (P1=0.059, P2=0.095), ultimate strain(P1=0.154, P2=0. l65), and average elastic modulus(P1=0.814, P2=0.818) were not statistically significant. Only strain energy density was the statistically significant difference between group 2 and group 5(P1=0.008, P2=0.022). As a result, there were observed that the ultimate stress and strain energy density were decreased and ultimate strain was decreased but there were not statistically significant differences hetween groups because of the small number of samples, and there will be advantages for graft to avoid ahrasive wear on the tunnel edge and lateral femoral condyle. But, more studies are needed for human being in the future.

Treatment of chronic localized osteomyelitis is the same as the other osteomyelitis, that is, curettage and debridement of all dead tissue which is called saucerization. After saucerization there leaves empty cavity and autogenous bone graft has been used for filling the cavity in lower extremity hecause of weight bearing and avoiding fracture. We treated seven cases of chronic localized osteomyelitis with one-staged saucerization and cancellous chip allograft and retrospective analysis was done. All healed without complication and no recurrence was ohserved. Most orthopaedic surgeons are not willing to use allograft on the site of osteomyelitis because of the fear of recurrence. But. we think that as far as complete removal of infected and dead tissue, allograft could he a good solution in terms of rapid remodelling and early weight hearing. Another advantages of allograft are to get a large amount of bone and no damage of iliac apophysis. In summary, one-staged saucerization and cancellous chip allograft would he very useful treatment for chronic localized osteomyelitis.

PURPOSE: To evaluate the change of the sensitivity and resistance to ciprofloxacin of isolates in bacterial ocular disease, bacterial keratitis and conjunctivitis. METHODS: From January 1992 to December 1999 in KyungHee Medical Center, we carried out direct smear and culture from conjunctiva and cornea and studied retrospectively. RESULTS: A total of 420 bacteria and fungi were isolated and 39 strains were identified. Antibiotic sensitivity test was done in isolated bateria and fungi. Gram-positive bacteria accounted for 324 of all bacteria, gram-negative organisms for 81 in isolated causative organisms. Major causative organisms of bacterial ocular disease, bacterial keratitis and conjunctivitis are coagulase-negative staphylococcus, Staphylococcus aureus, Pseudomonas aeruginosa in that order. Among 420 isolates, 405 bacteria and 15 fungi was isolated. In vitro examination for susceptibility and resistance of causative organisms to ciprofloxacin was done in 67 of 420 isolates. Of the 67 isolates, 57 were sensitive to ciprofloxacin and 10 were resistant to ciprofloxacin. All resistant cases to ciprofloxacin was 2 cases in 1994, 7 cases in 1998, and 1 case in 1999. CONCLUSIONS: The resistance to ciprofloxacin has a increasing tendency. Therefore, ciprofloxacin should be used carefully, when used for prevention of infection and primary treatment in mild ocular diseases.

We present a case of iatrogenic lumbar foraminal stenosis caused by bone-cement leakage during vertebroplasty, successfully managed using transforaminal endoscopic lumbar foraminotomy (TELF). Vertebroplasty is an effective treatment for osteoporotic vertebral compression fractures (VCFs); however, complications such as bone-cement leakage can lead to vascular or neurological issues, including lumbar radiculopathy. TELF is a minimally invasive surgical option for addressing various forms of lumbar foraminal stenosis. An 82-year-old female patient presented to Gachon University Gil Medical Center with severe right inguinal pain radiating to the anterior thigh and knee. Six months prior, she had undergone vertebroplasty at the L3 level for an osteoporotic VCF at another hospital. Following the procedure, she developed radicular leg pain with a diminished knee jerk reflex, which progressively worsened despite extensive conservative treatment. Magnetic resonance imaging and computed tomography revealed right-sided L3–4 foraminal stenosis caused by bone-cement leakage from the prior vertebroplasty. TELF was performed under local anesthesia to decompress the affected area. Bone-cement fragments, along with hypertrophic bone and ligaments, were successfully removed, achieving sufficient decompression of the exiting nerve root. The patient experienced immediate postoperative pain relief. This case represents the first documented instance of endoscopic decompression for iatrogenic foraminal stenosis following vertebroplasty. TELF, performed safely under local anesthesia, demonstrates its effectiveness as a minimally invasive solution for this rare complication.

BACKGROUND: Neutropenia can be easily found in previously healthy children associated with various medical conditions, and the clinical course ranges from transient benign to life threatening. This study aimed to investigate the etiology, clinical characteristics, and clinical courses of neutropenia in previously healthy children. METHODS: We evaluated 215 previously healthy children under aged 18 years who diagnosed with neutropenia in two hospitals. Clinical and laboratory features were analyzed retrospectively based on the medical records. RESULTS: Transient infectious neutropenia (TIN) accounted for 97.7% of cases and chronic neutropenia (CN), for 2.3%. An infectious agent was identified in 128/210 (61%) patients with TIN, and the most frequent agents were viruses (46.5%). The most common viral agent was respiratory syncytial virus (RSV) (29%). TIN subgroups exhibited no differences in severity according to infectious agent (virus, bacteria, Mycoplasma); however, neutropenia severity differed among viral agents [mild-to-moderate neutropenia in the RSV group (857.3±293.3/µL) and moderate-to-severe neutropenia in the parainfluenza group (567.3±198.1/µL); P=0.017]. All patients with CN had anti-neutrophil antibody positivity (autoimmune neutropenia, AIN), and moderate-to-severe neutropenia predominated. The median duration of TIN was 8 days (range, 3–286 days), and it was significantly longer for AIN at 330 days (range, 217–730 days) (P=0.000). The median duration of neutropenia was also different according to each viral agent, with 4 days (range, 3–11 days) for the RSV group and longer durations for 3 other groups (influenza, parainfluenza, other respiratory viruses) (P=0.015). CONCLUSION: Neutropenia in previously healthy children is usually of transient infectious origin, with mild-to-moderate severity, and it resolves spontaneously without complications.
