The purpose of our study was to compare the clinical results between arthroscopic bone fixation on intertubercular groove using suture anchor and soft tissue fixation at the rotaor interval for biceps tenodesis when partial tear or instability of biceps tendon accompanied with rotator cuff tear. From January 2010 to January 2012, 34 cases who were performed biceps tenodesis for partial tear or instability were enrolled in our study. Mean follow-up period was 30.2 months. Bone fixation using suture anchor was performed in 18 cases, and soft tissue fixation was performed in 16 cases. Clinical result was evaluated by pain visual analogue scale (VAS), Speed test, Yergason test, muscle strength, and Constant score. Pain VAS of cases with soft tissue fixation was significantly higher than that of cases with bone fixation at 6 months and final follow-up. Positive results for the final follow-up Speed and Yergason test were checked in 4 cases (25%) with soft tissue fixation and 1 (5.6%) with bone fixation. The Popeye deformity was seen in 4 cases (25%) with soft tissue fixation and 2 (11%) with bone fixation. Constant score was improved 47 to 78 in cases with soft tissue fixation and 48 to 86 in cases with bone fixation. In patient with partial tear or instability of biceps tendon accompanied with rotator cuff tear, biceps tenodesis using soft tissue fixation showed worse result compared with bone fixation because of long duration of the pain. Therefore, when performing the biceps tenodesis, bone fixation will be recommended.

The rapidly increasing rate of shoulder arthroplasty is certain to increase the number of revision arthroplasties because of parallel increases in complication numbers. It has been widely reported that the causes of revision shoulder arthroplasty include rotator cuff deficiency, instability, glenoid or humeral component loosening, implant failure, periprosthetic fracture, and infection. Revision arthroplasty can be technically challenging, and surgical options available for failed shoulder arthroplasty are limited, especially in patients with glenoid bone loss or an irreparable rotator cuff tear. Furthermore, the outcomes of revision arthroplasty are consistently inferior to those of primary arthroplasty. Accordingly, surgical decision making requires a good understanding of the etiology of failure. Here, we provide a review of indications of revision arthroplasty and of the surgical techniques used by failure etiology.

It is the purpose of this experimental study to investigate the alterations of the amount of adenosine nucleotides and adenylate energy charge in the acute focal cerebral ischemia of cats utilizing high performance liquid chromatography and to make a comparative study of protective effects of recirculation and combined therapy with mannitol, steroid and barbiturate. Acute focal cerebral ischemia in cats was induced by occlusion of the left middle cerebral artery through the postorbital technique. The experimental animals were divided into four groups according to the duration of occlusion time. The experimental results are obtained as follows: 1) In 1, 3 and 5 hour-occlusion groups, amount of adenosine triphosphate and summation of adenosine nucleotides decreased significantly to 21.4%, 5% & 0%, 44.0%, 29.9% & 10.8% of the sham control, respectively. Also in these groups adenylate energy charge decreased significantly to 62.7%, 38.7% and 30.7% of the sham control, respectively. It was suggested that the longer duration of occlusion time was, the more amount of adenosine triphosphate, summation of adenosine nucleotides and adenylate energy charge decreased significantly. 2) In 1 and 3 hour-occlusion groups, 2 hour-recirculation increased significantly amount of adenosine triphosphate and summation of adenosine nucleotides to 37.4% & 29.4%, and 62.1% & 58.3% of the sham control, respectively. Also in these groups recirculation increased significantly adenylate energy charge to 70.7% and 65.3% of the sham control, respectively. Whereas there was a slight increase of adenylate energy charge after recirculation in 5 hour-occlusion group, but not significant. 3) In the groups of recirculation following 5 hour-occlusion, pretreatment of combination of mannitol and steroid, or mannitol, steroid and barbiturate increased significantly amount of adenosine triphosphate, summation of adenosine nucleotides, and adenylate energy charge to 57.2% or 66.1%, 80.9% or 83.5% and 82.7% or 84.0% of sham control, respectively.

Percutaneous biopsy is the most frequent interventional radiographic procedure. Its increased use is relatedto new imaging techniques facilitating needle placement, greater safety of fine needle and advances in cytology.CT because of its characteristic high spatial and density resolution, permits the accurate localization of anylesion in the body. Because of the ability of CT scans to precisely localize lesions and biopsy needle, along withthe delineation of adjacent structure, it is widely used in percutaneous biopsy. Sixty-six cases of CT-guidedpercutaneous fine-needle biopsy were performed in order to diagnose suspected malignant or infectious disease(49malignant and 17 infectious) over a 7-month period(June 1984 through Dec. 1984). Most of these procedures wereperformed on, but not limited to, the lung(21), liver(20), and pancreas(7). The spine and nasopharynx could alsosafely be biopsied. 4 cases of hepatic abscesses were successfully drained following insertion of drainingcatheter under the CT-guidance. The overall accuracy of both suspected malignant and infectious disease was 82%.Complication rate was low as 6%(4 cases only in thorax). Neither complication require any further intervention.Three were self-limited pneumothoraces and one was minimal hemorrhage around the needle tract.

Free vascularized tissue transfer to preserve upper extremity amputation level is uncommon but very useful procedure. To cover the below-elbow amputee stump and restore the function of the elbow, we have used a free flap as a spare part concept from the contralateral hand which was so severely damaged that amputation was inevitable.

A hemiarthroplasty with biologic resurfacing of the glenoid is one procedure that can be performed in young patients where total shoulder arthroplasty may be difficult. The authors introduced two cases in which this procedure was performed. This approach is one treatment option for young glenoid humeral arthritis patients that addresses some of the shortcomings of an isolated hemiarthroplasty.
