The skin incision is about 4 to 5 cm made by the distal acromial edge in sagittal plane, The dissection takes place slightly over the acromial edge proximally and over the origin of the acromial deltoid part (the middle part of deltoid origin) distally.~After clearly revealing the region of the medial deltoid origin on the acromion, the acromionic deltoid origin is skinned only; of the edge of the acromion, and that maybe accrued by electric knife pen or periosteal elevator, without exposure the clavicular deltoid origin in the front and the deltoid origin on the spine of scapula in the back, the origin of the acromial deltoid is distanced laterally and distally, where the lateral edge, the lower surface of the acromion, under acromial bursa and the rotator cuff are exposed clearly.~Throw this approach can be made acromioplasty and rotator cuff tears repair especially upper part of rotator cuff tear very easily.~For wound closure the acromionic deltoid origin is reattached to the acromial edge by long period synthetic absorbable sutures as PDS and PDO, or non absorbable sutures as Polyester suture, under skin and skin sutures are made.
The incision is very useful and easy for the direct lateral shoulder joint exposure.
