Objective To explore the feasibility of the small figure-L unilateral transternal incision for the treatment of anterior mediastinal tumor and cyst. Methods Eighteen patients with anterior mediastinal tumor or cyst were enrolled in the study. Under general anesthesia, after a 8 to 10 cm middle skin incision was made, a unilateral figure-L partial sternotomy on the side occupied by the tumors was made in the third or forth intercestals space,taking into account the tumors size and location. Tumors were resected with excellent exposure. Results All but one tumors were completely resected during the operation. In 3 cases,tumors encroached on the adjacent lung tissue,and lung tissue was partially resected. In 2 cases, tumors invaded the pericardium, and the pericardium was partially removed.Mean operating time was 120 minutes( 80～140 minutes). The mean time of hospital stay was 10 days after the operation, and there was no complications. All patients were alive with a mean follow-up period of 24 months ( 8～36 months). Conclusion The figure-L unilateral sternotomy is an effective and useful minimally invasive approach for anterior mediastinal tumors.

[Objective]To investigate the clinical effect of saddle-shaped condylar plate in treating the fracture of the femoral intercondylar and supracondylar.[Method]Thirty-two cases with the fracture of the femoral intercondylar and sapracondylar,who were selected randomly were fixed by saddle-shaped condylar plates after reduction,of which 8 cases of patellar fractures accompanied with ipsilateral fracture of the femoral condylar.[Result]All cases were completely healed during the follow-up study of 4 months to 2 years,all cases achieved bone union in 5～9 months.[Conclusion]The design of the plate conforms to the principle of biomechanics and is good for the heal of the fracture.The saddle-shaped structure makes the plate and the cannular bone tangent as fixing so it can reduce the putrescence of the bone which is caused by pressure;The arch-bridge-shaped juncture and the mechanical bolts which are fixed across can strengthen the power of anti-bending and anti-rotation of the broken ends of the fractured bone.The stability of the fixation enables the patient do the functional exercise after the operation as soon as possible.It has definite clinical value and is worth of popularization.
