INTRODUCTION: Open reduction and internal fixation has long been accepted as optimal treatment for displaced olecranon fractures based on poor results seen with conservative management. With the presence of comminution, tension-band wiring constructs are contraindicated due to tendency to compress through fragments, thereby shortening the articular segment. Therefore, plate fixation is typically employed. Our hypothesis was that in a comminuted fracture model, 2.7 mm reconstruction plating without locking screws will perform equally to 3...

BACKGROUND: Clinical outcomes of terrible triad injuries (TTIs) of the elbow are historically poor. To date, it is still debatable whether the coronoid needs to be fixed and if so, how and in which sequence. METHODOLOGY: Between 2010 and 2013, 13 patients were treated surgically for acute TTIs of the elbow at a Tertiary Level 1 Trauma Centre by a single surgeon, using a standardized protocol, which included coronoid-brachialis complex fixation via pull-through trans-osseous sutures, radial head fixation or prosthetic replacement and a repair of the lateral ulnar collateral ligament...

Atraumatic acute carpal tunnel syndrome is a rare type of median nerve neuropathy caused by etiologies that increase compartment pressure in the carpal tunnel. This report describes a patient with flexor tendon abrasion as an unusual complication of distal radioulnar joint arthritis. This abrasion caused a hematoma to form in the carpal tunnel during anticoagulant treatment with apixaban, resulting in recurrent acute carpal tunnel syndrome.

INTRODUCTION: Pain and disability often persist following hip (THR) and knee replacement (TKR) surgery predisposing patients to increased risk of falling. This study identified pre-operative predictors for post-operative falls in TKR and THR patients, and the incidence and circumstances of falls in the 12 months post-surgery. MATERIALS AND METHODS: A survey was undertaken of patients before THR and TKR, and was repeated 12 months post-operation. The survey included (1) medical history and medications usage, (2) pain and function, (3) health-related and physical activity and (4) fear of falls and history of falls questionnaires...

INTRODUCTION: Distal biceps brachii tendon rupture can lead to 30-40% power loss of elbow flexion and up to 50% of forearm supination. Re-fixation of the distal biceps brachii tendon is recommended to warrant an adequate quality of the patient's life. This study reports the isometric and isokinetic results after anchor re-fixation 2.5 years after surgery. PATIENTS AND METHODS: Between 2007 and 2010, 69 patients with distal biceps brachii tendon tear underwent a suture anchor reattachment...

INTRODUCTION: Subtrochanteric fractures are more difficult to treat than other proximal femoral fractures. The aim of this study was to report the outcomes for patients with subtrochanteric fractures treated using a cephalomedullary nail following open reduction and cerclage wiring versus closed reduction alone, regarding health-related quality of life (HRQoL) and social function. MATERIALS AND METHODS: We performed a prospective cohort study including patients aged 60 years or older suffering fragility subtrochanteric fractures of the femur treated with cephalomedullary nails, with a minimum 2-year follow-up...

INTRODUCTION: Secondary cuff failure after shoulder replacement is disabling and often requires additional surgery. Increased critical shoulder angle (CSA) has been found in patients with cuff tear compared to normal subjects. The interobserver reliability of the CSA and the relationship between CSA and symptomatic secondary cuff failure after shoulder replacement were investigated. MATERIALS AND METHODS: Nineteen patients with symptomatic cuff failure after anatomic shoulder replacement (mean FU 45 months) were compared to a control group of 29 patients showing no signs of symptomatic cuff failure (mean FU 105...

INTRODUCTION: The rationale of focal articular prosthetic resurfacing used as a primary arthroplasty procedure in the treatment of articular cartilage defects is still under debate. Conflicting reports raise concern about high rates of re-operations and continued development of osteoarthritis, while others have reported good outcomes. The goal of this paper is to present the long-term results of two patients with a 12-year follow-up and to report the results of a literature review. MATERIALS AND METHODS: Two patients (male, 70 years; female 63 years) with a follow-up of 12 years were reviewed...

INTRODUCTION: Although the extended lateral approach is typically considered the gold standard of treatment for intra-articular calcaneal fractures, a limited lateral approach may be a good alternative in select cases. METHODS: Forty-seven consecutive patients with intra-articular calcaneal fractures treated using the sinus tarsi approach between March 2010 and April 2015 were retrospectively reviewed. The functional outcomes [including arc range of motion, Visual Analog Scale (VAS) score, and the American Orthopedic Foot and Ankle Society ankle/hindfoot (AOFAS) score], bony outcomes (bony restoration and bony union), and complications were evaluated...
