Incidence of early radiolucent lines after glenoid component insertion for total shoulder arthroplasty: a radiographic study comparing pressurized and unpressurized cementing techniques.

Background: Total shoulder arthroplasty (TSA) is commonly performed for arthritic conditions of the shoulder. The outcome after TSA is generally good, but there are several modes of failure, with one of the more common reasons being glenoid loosening. One possible cause for glenoid loosening is inadequate cementation technique.

Hook of hamate pull test.

Hook of hamate fractures are often missed despite a distinct history. The purpose of this report was to describe a specific physical examination test that is diagnostic for a hook of hamate fracture, the hook of hamate pull test. It is highly sensitive and was positive in a consecutive series of 5 patients treated for a hook of hamate fracture.

Treatment of heterotopic ossification of the elbow following burn injury: recommendations for surgical excision and perioperative prophylaxis using radiation therapy.

Background: Heterotopic ossification (HO) is reported to occur in 0.1-3.3% of elbows after a severe burn, and can significantly limit elbow motion and upper extremity function.

Anteromedial elbow arthroscopy portals in patients with prior ulnar nerve transposition or subluxation.

Purpose: The purpose of this study was to document management strategies and complications relating to the use of anteromedial portals for elbow arthroscopy in a series of patients with subluxating or previously transposed ulnar nerves.

Methods: A review of 913 elbow arthroscopies showed that 59 elbows with a subluxating or previously transposed ulnar nerve required anterior compartment arthroscopic surgery. The patients with subluxating nerves had proximal anteromedial portals established by reducing and holding the nerve behind the epicondyle with a thumb while establishing or entering the portal.

Arthroscopic release of the stiff elbow.

Treatment of the stiff elbow by arthroscopic capsular release is a relatively new and effective procedure. The surgery is technically demanding and is not indicated in all cases of stiff elbow. Although neurologic complications are unusual, they can be severe and permanent.

Proximal ulna fractures.

Proximal ulna fractures are relatively common. They range in severity from a simple transverse olecranon fracture to a highly complex fracture dislocation involving a comminuted coronoid process. The anatomy, fracture pathology, treatment approach, and rehabilitation are presented in this article.

Chronic glenohumeral dislocation.

The evaluation and management of chronic glenohumeral dislocations can be challenging. By definition, chronic glenohumeral dislocations represent injuries that were not identified at the time of injury. Therefore, the primary goal is to avoid circumstances in which these injuries are not recognized.

Core decompression for nontraumatic osteonecrosis of the humeral head: a technique article.

Core decompression may used in the management of early stage, precollapse nontraumatic osteonecrosis of the humeral head. We propose a technique without risk of complications associated with injury to the biceps tendon or the blood supply to the humeral head.

Arthroscopic revision of Bankart repair.

The success of revision surgery for failed Bankart repair is not well known. This purpose of this study was to report the success rates achieved using arthroscopic techniques to revise failed Bankart repairs. Twelve arthroscopic revision Bankart repairs were performed on patients with recurrent unidirectional shoulder instability after open or arthroscopic Bankart repair.

Computer-assisted localization of osteoid osteoma: an initial experience.

This article evaluates our initial experience with computer-assisted localization of osteoid osteoma. Nine patients with osteoid osteoma underwent minimally invasive computer-assisted surgery. Patients were followed prospectively for symptomatic relief and complications for an average of 31 months.

Loose bodies in a sublabral recess: diagnosis and treatment.

A case of a 26-year-old male with symptoms resulting from loose bodies residing in a sublabral recess is presented. Operative intervention using the standard arthroscopic portals in addition to an accessory posterior portal was successful in removing the loose bodies and approximating the edges of the sublabral foramen. The shoulder is a complex region made up of numerous anatomic structures, which if damaged may be responsible for a patient's pathology.

Fixation of greater tuberosity fractures: a biomechanical comparison of three techniques.

The fixation of displaced greater tuberosity fractures with 5-0 Fiberwire, Fiberwire tape, and 5-0 Ethibond sutures was compared in 12 pairs of cadaveric humeri. A simulated fracture was created and fixed with suture in a figure-of-eight pattern. The tuberosity was cyclically loaded and its displacement measured.
