BACKGROUND: The purpose of this study was to evaluate the clinical and radiographic outcomes of internal fixation with locking T-plates for osteoporotic fractures of the proximal humerus in patients aged 65 years and older. METHODS: From January 2007 through to December 2015, we recruited 47 patients aged 65 years and older with osteoporotic fractures of the proximal humerus. All fractures had been treated using open reduction and internal fixation with a locking T-plate. We classified the fractures in accordance to the Neer classification system; At the final follow-up, the indicators of clinical outcome-the range of motion of the shoulder (flexion, internal rotation, and external rotation) and the presence of postoperative complications-and the indicators of radiographic outcome-the time-to-union and the neck-shaft angle of the proximal humerus-were evaluated. The Paavolainen method was used to grade the level of radiological outcome in the patients. RESULTS: The mean flexion was 155.0° (range, 90°–180°), the mean internal rotation was T8 (range, T6–L2), and the mean external rotation was 66.8° (range, 30°–80°). Postoperative complications, such as plate impingement, screw loosening, and varus malunion were observed in five patient. We found that all patients achieved bone union, and the mean time-to-union was 13.5 weeks of the treatment. The mean neck-shaft angle was 131.4° at the 6-month follow-up. According to the Paavolainen method, “good” and “fair” radiographic results each accounted for 38 and 9 of the total patients, respectively. CONCLUSIONS: We concluded that locking T-plate fixation leads to satisfactory clinical and radiological outcomes in elderly patients with proximal humeral fractures by providing a larger surface area of contact with the fracture and a more rigid fixation.

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.

In the treatment of Tb.knee, the preservation of mobility is an important issue, there are many difficulties due to pain and swelling in the trial of early ROM exercise, and various problems such as the recurrence of Tb. lesions, delayed wound healing and draining sinus formation. We analysed 30 cases of Tb. knee treated with synovectomy during 10 years since March, 1979. In Group I (25 cases), early ROM exercise were started about 4 weeks after synovectomy. And in Group II (5 csses), arthroscopic adhesiolysis was performed after minimum 6 month immobilization and chemotherapy following synovectomy. We compared the two Groups and the results were as followings: 1. Male was 15 patients and female was 15 patients, the average age was 28.1 years. 2. The average follow-up period was 18.3 months. 3. In Group I, the ROM exercise was performed before 4 weeks in 9 cases and after 4 weeks in 16 cases postoperatively. The average final ROM was 68.9° 4. Draining sinus formation was in 4 cases in Group I. 5. In Group II, arthroscopic adhesiolysis was performed in 5 cases after synovectomy and chemotherapy for average 8.8 months ranging from 6 to 14 months. 6. The average final ROM at follow-up was 111° in Group II. 7. In a case with the severe involvement of bone and cartilage in Tb. lesion at the synovectomy, ROM was reduced gradually to 50° after arthroscopic adhesiolysis. We could gain ROM of 120° by TKR. 8. Draining sinus formation was not found in Group II.

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

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.

Between December 1994 and December 1996, 42 patients underwent arthroscopic meniscal repair in our institute. Among them, 31 patients with a follow up more than one year were reviewed. Mean age was 24.4 years(range, 18-52 years) and mean interval between onset of symptom and opera- tion was 12.3 months(range, 3 days-6 years). The associated injuries were tibial plateau fracture(6 cases), anterior cruciate ligament injury(4 cases) and posterior cruciate ligament injury(2 cases). The type of tear were longitudinal in 28 cases(90%) and combined in 3 cases(10%). Most of the meniscal tear were encountered in posterior hom(12 cases, 39%) and middle portion(11 cases, 35%). Out side to in technique was used in anterior horn tears and inside to out technique in middle or posterior hom tears. In tibial plateau fractures, arthroscopic assisted reduction was performed with autogenous bone graft. Ligament reconstructions were performed in the cases of associated cruciate ligament injury. According to Ikeuchis grading system, the result was satisfactory(excellent or good) in 23 cases(74%), fair in 6 cases(19%) and poor in 2 cases(6%). But in the cases of isolated meniscal injury, the result was satisfactory in 95%. The result of arthroscopic repair in the meniscal tears associated with other intra-articular injuries seems to be worse than that of the isolated injuries.

Fractures of the capitellum humeri are rare and the recommendations for treatment vary. It can involve a significant portion of the articular surface, rendering the elbow joint unstable. In this situation, it is desirable to reduce and internally fix the capitellar fragment, because this restores the articular surface and augments joint stability. We experienced two cases of capitellar fractures which one case was spontaneously anatomical reduced and the other case was treated by open reduction. In one case the capitellar fragment was spontaneous reduced to a stable position although it was noticed radiographically as an unstable displaced fracture preoperatively. The other case was treated by open reduction and internal fixation with 3.5mm, small, AO, cannulated screw and K-wire. Both cases are reported here with references.

BACKGROUND: We investigated the effectiveness of pain management and the adverse events of intravenous (IV) patient-controlled analgesia (PCA) after orthopedic surgery. METHODS: From September 2014 and August 2015, we performed a retrospective analysis of 77 patients who underwent orthopedic surgery of the shoulder or the elbow in our hospital. The composition of the intravenous PCA administered to the patients was as follows: 250 mg of dexketoprofen trametamol, 70 mg of oxycodone, and 0.6 mg of ramosetron, which were made up to 79 ml of normal saline. We evaluated and statistically analyzed the difference in the visual analogue scale (VAS) scores for pain at immediate postoperation, at 24 hours of PCA, at 72 hours of PCA, and after discontinuation of PCA and in the incidence of adverse events. RESULTS: We found that VAS score decreased for 3 postoperative days and that with discontinuation of IV PCA a meaningful change in VAS score was no longer seen. Of the 77 patients, 22 presented with adverse events (28.6%). We terminated IV PCA temporarily in the 21 patients who presented with adverse events; we terminated analgesia permanently in one patient (1.2%). Consequently, 76 of 77 patients carried out IV PCA till the designated period. CONCLUSIONS: Intravenous PCA after orthopedic surgery of the shoulder or the elbow may be accompanied with adverse events. Careful assessment of the patient and treatment of the adverse outcomes are key to a successful maintenance of PCA and to a successful management of postoperative pain.
