Triceps tendons: a biomechanical comparison of intact and repaired strength.

Hypothesis: Our hypothesis was that the autograft-augmented direct repair of torn triceps tendons would have strength superior than that of direct repair when compared to the strength of intact distal triceps tendons.

Materials And Methods: The strength of the intact distal triceps tendon in 8 unpaired, fresh frozen cadaver specimens was measured to tendon failure by uniaxial tension in the sagittal plane. The torn triceps tendons were then repaired by direct repair (sutures through drill holes) or an autograft-augmented direct repair.

Techniques for suture anchor removal in shoulder surgery.

Although suture anchor complications after arthroscopic shoulder surgery are uncommon, they can be devastating, such as articular cartilage or bone loss secondary to a dislodged or prominent suture anchor. Proper insertion of the anchor is the most important factor in the prevention of this complication, but if a complication occurs, prompt recognition and treatment are important to prevent damage to the shoulder. The goals were to (1) discuss strategies for preventing or dealing with dislodged or prominent suture anchors and (2) introduce techniques for removal of these implants.

Anatomical acromioclavicular ligament reconstruction: a biomechanical comparison of reconstructive techniques of the acromioclavicular joint.

Background: Current surgical treatments for acromioclavicular separations do not re-create the anatomy of the acromioclavicular joint.

Hypothesis: Anatomical acromioclavicular reconstruction re-creates the strength of the native acromioclavicular joint and is stronger than a modified Weaver-Dunn repair.

Study Design: Controlled laboratory study.

Simple techniques for passing suture through bone.

Sutures often must be passed through bone tunnels to repair soft tissue or bone. Three easy, inexpensive, and time-saving suture-passing techniques are described in this article. These techniques, which involve using 1 of 3 readily available instruments (Angiocath, Hewson suture retriever, Keith needle), can be applied in many different orthopedic surgical procedures and may save much time and aggravation in the operating room.

The accuracy of distal posterior interosseous and anterior interosseous nerve injection.

Purpose: To standardize a technique of delivering a local anesthetic to the posterior interosseous nerve (PIN) and anterior interosseous nerve (AIN) by using the anatomic landmarks of the wrist and to evaluate the accuracy of the technique in a cadaver model.

Methods: Techniques for PIN and AIN injection and for PIN injection alone are described. Techniques were tested in a fresh frozen cadaver model by using methylene blue injections.
