Definition of coordinate system for three-dimensional data analysis in the foot and ankle.

Background: Three-dimensional data is required to have advanced knowledge of foot and ankle kinematics and morphology. However, studies have been difficult to compare due to a lack of a common coordinate system. Therefore, we present a means to define a coordinate frame in the foot and ankle and its clinical application.

An unusual cause of pain post ankle arthrodesis in patients with rheumatoid arthritis.

Rheumatoid arthritis is an autoimmune disease which frequently affects the ankle and foot. End stage ankle arthritis from rheumatic disease is commonly managed by the established practice of ankle arthrodesis. Among the adverse sequelae causing pain following this surgery is infection, pseudo-arthrosis and non-union.

Serum albumin and total lymphocyte count as predictors of outcome in hip fractures.

Background & Aims: Hip fractures are a significant cause of mortality and morbidity in the elderly. Malnutrition is a significant contributor to this, however no consensus exists as to the detection or management of this condition. We hypothesise that results of admission serum albumin and total lymphocyte count (TLC), as markers of Protein Energy Malnutrition (PEM) can help predict clinical outcome in hip fracture patients aged over 60 years.

Evaluation of Hylamer-zirconia hip arthroplasty in patients less than 50 years of age.

The purpose of this prospective study was to determine the clinical outcomes of patients who had total hip arthroplasties with a zirconia (Zr) - Hylamer pairing. Fifty-eight consecutive cemented total hip arthroplasties with a Hylamer cup and 22.25 mm Zr head were examined for component wear and failure.

Pseudoaneurysm of the brachial artery following humeral fracture.

The frequency of peripheral artery aneurysms in the upper extremities is less than in the lower extremities. Diagnosis and surgical treatment are important because upper extremity aneurysms can severely compromise the function of a limb and possibly lead to the loss of an arm or fingers. Very rarely, posttraumatic upper extremity pseudoaneurysms show symptoms after a long period of time.

Early mobilization in a removable cast compared with immobilization in a cast after operative treatment of ankle fractures: a prospective randomized study.

Background: The aim of operative treatment for ankle fractures is to allow early movement after internal fixation. The hypothesis of this study was that early mobilization would improve functional recovery in patients after surgery for ankle fractures.

Methods: In a prospective randomized controlled study, 66 consecutive patients with ankle fractures that required open reduction and internal fixation (ORIF) were assigned to one of two postoperative regimens: immobilization in a nonweightbearing below-knee cast or early mobilization in a removable cast.

Impaction allografting and the Kerboull acetabular reinforcement device: 35 hips followed for 3-7 years.

Background: The incidence of acetabular loosening with segmental and cavitatory bone loss increases as the number of total hips implanted increases. Revision hip arthroplasty using impacted bone graft and an acetabular reinforcement device is one solution to this problem.

Patients And Methods: Clinically and radiographically, we assessed 35 hips in 33 patients who had undergone revision hip arthroplasty using impaction grafting and the Kerboull acetabular reinforcement device.

Outcome after single technique ankle arthrodesis in patients with rheumatoid arthritis.

The established treatment for severe rheumatoid arthritis in the ankle is arthrodesis. Numerous reports in the literature describe outcomes in patients with degenerative and posttraumatic arthrosis and rheumatoid disease. This has led to results that are difficult to interpret.
