Validation of minimally invasive articular cartilage sparing technique for olecranon osteotomy.

Background: The authors present a cadaveric validation of a minimally invasive articular cartilage preserving olecranon osteotomy technique for use in the operative management of distal humeral fractures.

Methods: Twenty-four elbows in six male and six female formaldehyde embalmed cadavers were dissected. With the cadaver placed in a lateral decubitus position, a posterior sub-periosteal dissection was performed to the medial and lateral aspects of the olecranon at the level of the joint and Mini Hohmann retractors were inserted into each side of the ulnohumeral joint.

Determining the ideal osteotomy for stemless total shoulder replacement: a cadaveric study.

Hypothesis: We sought to determine the angle of osteotomy that produces a circular humeral cut surface.

Methods: A total of 49 cadaveric shoulders, from 25 cadavers, underwent sequential humeral head osteotomy from 180° (vertical, in line with the humeral diaphyseal shaft), in 10° increments, until the rotator cuff insertion was encountered. At each stage, the anteroposterior (AP) and superoinferior (SI) distances were recorded.

Patient compliance with venous thromboembolism prophylaxis (VTE).

Venous thromboembolic disease (VTE) comprises pulmonary embolism (PE) and deep vein thrombosis (DVT), and causes morbidity and mortality, particularly in trauma and orthopaedic patients. Prevalence of 0.9% and 1.

Olecranon bursitis: a systematic overview.

Background: Olecranon bursitis is a common condition where the bursal cavity, superficial to the olecranon, becomes inflamed. This can occur either with or without infection and has been given pseudonyms relating to the repeated minor trauma from external pressure that often predisposes. As a result of the multiple aetiologies, olecranon bursitis can present to any medical specialty with reasonable frequency and, although many therapies are described, a single, evidence-based and standardized treatment pathway is not well described.

Disassociation at the head-trunnion interface: an unseen complication of modular hip hemiarthroplasty.

A woman in her mid-90s underwent a left uncemented bipolar hemiarthroplasty for an intracapsular femoral neck fracture. Postoperative radiographs at 48h showed a disassociation of the left femoral prosthesis at the head-trunnion interface, with the bipolar head remaining in the acetabulum. There was no preceding trauma and the patient had mobilised postoperatively.

Stretching has no effect on tennis serve performance.

Stretching prior to vigorous physical activity has been shown to decrease high-force muscular performance, but little is known about the effect of stretching on speed and accuracy movements. Serving percentage and radar measurements of ball speed were studied to examine the acute effect of stretching on tennis serve performance. Eighty-three tennis players from beginning level to advanced volunteered to serve following traditional (T) warm-up and traditional plus stretching (S) conditions.
