Serum creatine phosphokinase(CPK) levels were measured serially in 20 adults with closed tibial shaft fractures, CPK activity increased significantly after fracture(p < 0.01). High energy and delayed healing fractures had significantly higher levels of CPK than low energy and normally healing fractures, respectively. Thus, CPK determinations could be used to assess the severity of trauma and possible prognosis of the healing in tibial shaft fractures.

Many types of meniscal anomalies have been reported. The authors encountered two cases of anomalous insertion of the anterior horn of the medial menisci to the lateral femoral condyle which ran along the course of the anterior cruciate ligament(ACL) without connecting ACL. These anomalies were noted during arthroscopic surgery of the ipsilateral knee for a torn discoid meniscus, and a patellar fracture. A 34-year-old woman had a horizontal tear of the lateral discoid meniscus. We performed arthroscopic partial meniscectomy of the inner torn portion of the lateral discoid meniscus and contoured it to resemble a normal meniscus. An anomalous insertion of the medial meniscus was found on examination of the joint during surgery. A 32-year-old man had a patellar fracture and we performed reduction under arthroscopy and internal fixation with cannulated screws. The same anomalous insertion of the medial meniscus was found on examination of the joint during surgery. We report the cases with review of literature.

This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

PURPOSE: To evaluate the functional outcome after surgical treatment for displaced fractures of proximal humerus and assess the final results according to surgical methods. MATERIALS AND METHODS: Thirty-three cases with follow-up over 12 months were divided into three groups: double tension band wiring (Group I, 14), plate fixation (Group II, 10) and closed reduction with internal/external fixation (Group III, 9). The pain index, the self-assessed functional score and the range of motion were obtained. RESULTS: Anatomical reduction was best obtained in group II and fractures united in 11-16 weeks. The pain index was worst in group III and the functional score of group I (80+/-12.2%) was higher than in the others (II: 69+/-15.7%, III: 55+/- 7.9%). The range of motion was worst in group III. Complications were noted in 9 cases, which occurred mostly in group II and III. CONCLUSIONS: Double tension band wiring in displaced proximal humerus fracture demonstrated that it provides a sufficient fixation for early rehabilitation and union, while minimizing complication

Since Klemm introduced the concept of antibiotic-containing bone cement for the treatment of chronic osteomyelitis, a number of studies have demonstrated the positive results of this therapy. It has been proved that antibiotic-containing bone cement continuously releases high levels of atibiotics locally into the infected and avascular wound environment. Antibiotic-containing bone cement provides several distinct advantages over irrigation-suction drainage. The major objective of this study is to analyze the results of therapy using antibiotic-containing bone cement beads for chronic osteomyelitis. The authors analyzed 21 cases of chronic osteomyelitis in patients who had been treated by saucerization and antibiotic-containing bone cement beads at Chosun University Hospital, between February 1990 and January 1993. Each patient's case was followed for at least thirteen months after operation. The results are as follows: 1. The causes of osteomyelitis were postoperative complications(10 patients), open fracture(8 patients), and hematogenous osteomyelitis(3 patients). 2. Staphylococcus aureus was the most common organism causing osteomyelitis, followed by Pseudomonas. 3. The femur was the most common location of lesion(11 patients) followed by the tibia(7 patients), the humerus(2 patients) and the ulna (1 patients). 4. Pus drainage was stopped in 13 cases with one insertion of the beads, in 2 cases with two insertions and in 2 cases with three insertions. 5. Therapy using antibiotic-containing bone cement beads can be regraded as an effective method of increasing local antibacterial activity by releasing the antibiotic into surrounding tissue over a continuous period in the treatment of chronic osteomyelitis. Antibiotic-containing bone cement beads are useful in the treatment of chronic osteomyelitis.

Nineteen cases out of over 100 cases which had been reconstructed the deficient anterior cruciate ligament(ACL) by the bone-patellar tendon-bone(BPTB) autograft 12 months before or more(mean 15.8 months) were evaluated during the second-look arthroscopy. Before the second-look, the patients were evaluated the clinical results of ACL reconstruction by the Müller's knee rating score and the radiographical results by the lateral roentgenography of the fully extended knees. The location of the center of tibial tunnel from the anterior end of the line of the tibial plateau was 35.2%(range, 22 to 47%) on average. The average intercondylar roof angle was 36.6 degrees(range, 28 to 45 degrees). The mean percentage of roof impingement was

Authors analyzed the findings of nineteen cases of arthroscopic second-look operations after posterior cruciate ligament (PCL) reconstruction with autogenous bone-patellar tendon-bone (BPTB) and Trevira augmentation by two tunnel technique during the period from Nov, 1993 to Jan. l997 in fifty-one cases, along with the results of reconstruction in terms of clinica1 knee scoring, radiographichl and arthroscopic findings. The results were as follows; Age ranged fmm 20 to 53 years, the average being 32.3 years. Thirteen cases (68%) had associated knee injuries; five medial collateral ligament (MCL) injuries, four lateral collateral ligament (LCL) injuries, two associated injuries of MCL and medial meniscus, one both menisci and one associated injury of anterior cruciate ligament and MCL. The average period fmm PCL injury to reconstruction was 7 weeks (range, 1 to 52 wecks) and the mean period from PCL reconstruction to second-look operation was 20.3 months (range, 10 to 46 months). The average Miiller s knee score at the last follow-up was 86 paints. The radiographical results: The distance of posterior translation of the PCL reconstrueted knee compared with the normal sidc knee in posterior stress roentgenography was average 3.8mm (range, 0 to 1 1 mm). The position of the fernoral bone block on the plane of extended Blumansaats line, from the anterior end of the line, was average 32%. The level of proximal end of the tibial bone block according to the tibial tunnel orifice into the joint was mean negative 2.6 degrees position. The findings of arthroscopic second-look examination; In 9 cases (47%), the reconstructed ligamcnts were well covered with synovial tissue and looked like almost normal PCL. There were five cases (26%) of severe fragmentation, three cases (16%) of partial torn fibers of the grafted tendon. And one case showed the thinning of thc grafted tendon compared with the initial diameter at the time of reconstruction and one case showed overgrawth of the synovial membrane which suitounding the grafted tendon. All the Trevira which were augmented at the time of PCL reconstruction were ruptured. Twelve cases (63%) were stable, three cases (16%) were slightly lax and 4 cases (21%) showed laxity of the grafted tendon by the posterior drawer test and probing under arthroscopy, The isometricity which was checked at the time of PCL reconstruction was average 3.4mm. From the ahove results, PCL reconstruction with autogenous BPTB by the two tunnel technique seemed to be a valuable procedure, but there were some cases of unfavorable results. Authors think that a new graft fixation method is needed for resolving the problem mentioned above.

Cutaneous horn is a clinical diagnosis based upon the presence of a large protuberant mass of keratin. We report a case of cutaneous horn arising from dermatofibroma in a 31-year old woman. A silver whitish colored comical hyperkeratotic protruding lesion (1.0  0.7 cm size) from the red brown colored nodule was observed. Histopathologic findings showed characteristic findings of dermatofibroma and cutaneous horn. The lesion was removed by surgical excision.
