Arthroscopic treatment of fractures of the radial head.

An original technique for the arthroscopic diagnosis and treatment of the fractures of the radial head is proposed and described. The elbow arthroscopy is started with a 4.5-mm 30 degrees arthroscope from the proximal anteromedial portal and the anterior elbow is examined; then a proximal anterolateral portal is created and a full-radius blade inserted to take out the hematoma and to allow visualization of the radial head that is explored through the whole range of motion to visualize the fracture fragment.

Arthroscopic treatment of acute acromioclavicular joint dislocation.

An original technique for the treatment of acute acromioclavicular (AC) joint dislocations is proposed. It consists of a closed reduction and stabilization of the AC joint, positioning a cannulated screw between the clavicle and the coracoid under arthroscopic control, without any exposure to x-rays. The conoid and trapezoid ligaments are not sutured or reconstructed.

The double-twist knot: a new arthroscopic sliding knot.

A safe and easy-to-tie sliding knot is necessary for arthroscopic repair of rotator cuff tears and glenoid labrum lesions. We describe the double-twist knot (DTK) technique, having tested the knot's tensile strength and compared it with other commonly used arthroscopic knots. The DTK is a modified Lark's head knot that can be tied only on a double suture.
