PURPOSE: We studied results of the communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate in the elderly. MATERIALS AND METHODS: We studied 29 cases of communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate from April 2009 to April 2013. Fracture was classified according to AO/OTA classification. Postoperative clinical evaluation was performed with measurement of wrist range of motion (ROM) at last follow-up, modified Mayo wrist scoring system (MMWS), and visual analogue pain scale (VAS). Radiologic evaluation was performed with measurement of radial length on immediate postoperation and last follow-up, radial inclination, volar tilt and ulnar variance checked at the last follow-up using Sarmiento criteria. RESULTS: Using the MMWS, 13 cases were classified as 'good', 10 'fair', and 5 'normal'. The average wrist ROM was 88.5% for flexion, 92.2% for extension, 90.5% for adduction, and 94.0% for abduction. The average VAS was 1.7. On the last follow-up, average radius length, radial inclination and volar tilt did not show statistically significant improvement (p>0.05) compared to immediate post operation measurements, and according to Sarmiento criteria, 5 cases were classified as 'good', 14 'fair', and 7 'normal'. CONCLUSION: Treatment of severe communited distal radius fracture accompanied by bone defect with volar locking plate and allogenic cancellous bone graft is a satisfying and effective treatment method in the elderly.

BACKGROUND: Our aim was to make a comparative analysis of radiological and clinical outcomes of using either one or two interlocking distal screws on a Polarus intramedullary nail for the internal fixation of humeral shaft fractures. METHODS: From January 2008 to March 2014, we enrolled 26 patients with humeral shaft fractures who were operated on using intramedullary nails. The patients were divided into 2 groups according to how many interlocking distal screws were used to lock the Polarus nail: in group 1, a single interlocking distal screw was used in 12 patients; and in group 2, double interlocking distal screws, in 14 patients. We compared the degree of recovery of the displaced fracture fragments between the two groups. To compare the nonunion and shoulder function, we assessed each patient's modified American Shoulder and Elbow Surgerns (ASES) score. RESULTS: We found that 10 of 12 fractures achieved union in group 1, and 13 of 14 fractures, in group 2. We did not find a meaningful difference in the time to bone union between the two groups. The percentage of recovery of displaced fracture fragments until union was 66.9% for group 1 and 59.41% for group 2. At the final follow-up, we found that the scores for shoulder joint modified ASES was 78.7 for group 1 and 80.7 for group 2. CONCLUSIONS: Our results show that if locked appropriately, even a single screw on a Polarus nail can provide satisfactory radiological union and improved clinical outcome after intramedullary nailing of humeral shaft fractures.

PURPOSE: Our purpose was to retrospectively analyze clinical results of subpectoral tenodesis of the proximal biceps tendon using an interference screw. MATERIALS AND METHODS: We reviewed 23 cases of patients receiving tenodesis of the proximal biceps tendon between January 2008 and January 2009 for whom we had follow-up data for at least 1 year. Twenty-three cases were operated on using subpectoral tenodesis; 16 of these cases had a rotator cuff tear. The results were judged using a visual analog scale (VAS), ASES, tenderness on the biceps groove, fixation failure and the degree of deformity (BAD). RESULTS: VAS and ASES scores were significantly improved in all patients by the time of the final observation. There were no significant complications or fixation failures. The patients without a tear of the rotator cuff had a better result than patients with a tear of the rotator cuff, but the difference between the two groups was not significant (p>0.05). CONCLUSION: In patients with pathology of the long head of the biceps brachii, benefits of subpectoral interference screw tenodesis include pain relief, maintenance of functional biceps, muscle strength, and cosmesis. Subpectoral biceps tenodesis using interference screw fixation appears to be a promising, reproducible, reliable technique for addressing anterior shoulder pain related to pathology of the long head of the biceps brachii.

Effect of acetylcholine(ACh) and McN-A-343 on porcine coronary artery and rabbit thoracic aorta were investigated in isolated preparations with or without intact endothelium. In the porcine coronary artery, ACh produced concentration dependent contraction which was greater in rings without the endothelium than in intact endothelial rings, but McN-A-343 did not alter the basel tension in both tissues. ACh relaxed contraction induced by 5-hydroxytryptamine(5-HT) in only intact endothelial rings, while NcN-A-343 inhibited the 5-HT induced tension in both preparations dose dependently. Carbachol elicited a prominent contraction in both tissues. The carbacol-induced tension was markedly inhibited by McN-A-343 in either rings with or without endothelium, while ACh contracted further the tension. ACh and McN-A-343 did not after the KCi induced tension, but clearly potentiated the contraction induced by Bay K 8644 in intact endothelial rings. In rabbit thoracic aorta, ACh elicited contraction in a concentration-dependent fashion which was potentiated by removal of endothelium, but McN-A-343 did not affect the basal tension of both rings. ACh inhibited the 5-HT-induced contraction in only intact endothelial ring, but McN-A-343 did not change the contraction of both rings. Conclusively, ACh produces endothelium-dependent relaxation in both arteries, while McN-A-343 elevated endothelium-independent inhibition to 5-HT or carbachol-induced tension.

PURPOSE: To compare the clinical and radiologic outcomes of internal fixation using locking compression plate (LCP) or limited contact-dynamic compression plate (DCP) for patients with diaphyseal forearm fractures. METHODS: Forty-four patients with diaphyseal forearm fractures treated with either LCP (22 patients) or DCP (22 patients) were compared in regards to clinical outcomes, range of motion and Grace and Eversmann criteria at the last follow-up. Union rate and mean time to radiological union were also compared depending on comminution. RESULTS: Mean range of motion and Grace and Eversmann criteria between two groups did not show significant differences. Bony union was achieved in all patients. Although mean time to union was not different in simple fractures (15.5 weeks in LCP group vs. 13.8 weeks in DCP group), it was different between two groups in mutifragmentary fractures (14.8 weeks in LCP groups vs. 24 weeks in DCP group). CONCLUSION: Internal fixation using both LCP and DCP for diaphyseal forearm fractures yield satisfactory clinical and radiologic outcomes. In multifragmentary fractures, LCP can shorten radiologic union time than using DCP.

Epidermoid cyst is a benign tumor containing a layer composed by stratified squamous epithelium and filled with keratin. The epidermoid cyst after soft tissue damage such as bite, laceration could be caused by implantation of epidermal cells. There are reports of epidermoid cyst rarely occurred after surgical procedures such as bone graft or spine puncture. However, the report of epidermoid cyst associated with flap in the hand is very rare. We experienced such epidermoid cyst after the groin flap mimicking malignancy in the distal phalanx of the thumb. We found calcified mass with bony erosions in radiologic findings and heterotrophic signals and partial necrosis in magnetic resonance imaging that suggested malignancy. However, it was pathologically diagnosed as an epidermoid cyst. Therefore, we report the case and literature review.

Ultrasonography is used commonly for diagnosis and treatment in orthopedic field, because of low cost and radiation free imaging. Especially, in hand and wrist, where anatomical structures are located superficially, ultrasonography is very useful. Furthermore, major structures could be seen real-time, increasing safety and accuracy in operation. Therefore, some authors are trying ultrasonography-guided surgery around wrist and hand. This article reviewed the ultrasonography-guided surgery around wrist and hand with its technique, indication, and contraindication.

PURPOSE: To compare the accuracy of implantation by radiologic results between 3D Linker and navigation guided total knee arthroplasty. MATERIALS AND METHODS: Between February 2004 and April 2005, total knee arthroplasties were done in 25 knees with balanced gap-resection technique (group A) and 25 using kinematic navigation system(group B) by a single surgeon. All patients had standing long anteroposterior (AP) radiographs of the lower extremities and supine lateral radiographs of the knees at 6 weeks postoperatively. Mechanical axis deviation, alpha and beta, angles were measured on standing long leg AP views and alpha and beta angles on supine knee lateral views. Results were classified according to the deviation from the reference line and graded as excellent, good, and poor. The result was regarded as satisfactory when all five angles were excellent or good. RESULTS: The mean mechanical axis deviation was 1.11degrees in group A and 1.36degrees in group B and all were excellent in both groups. Regarding alpha.angles, 19 cases were excellent and, 6 good in group A and, 21 excellent and 4 good in group B. Regarding., angles, 22 cases were excellent and, 3 good in group A and, 23 excellent and 2 good in group B. Regarding.,, angles, 15 cases were excellent, 8 good and 2 poor in group A and, 15 excellent, 9 good, and 1 poor in group B. Regarding beta angles, 19 cases were excellent, 3 good and 3 poor in group A and, 23 excellent, and 2 poor in group B. There were no statistical differences between two groups in all five angles (p>0.05). An excellent implantation in all five angles was obtained in 28% in group A and 60% in group B (p<0.05). There were 80% of satisfactory cases in group A and 84% in group B with no statistical difference (p>0.05). CONCLUSION: Radiological results (mechanical axis and component angles) of total knee arthroplasty were satisfactory in 80% with balanced gap-resection technique and 84% with kinematic navigation system and showed no statistical difference.
