BACKGROUND Multiple rib fractures cause significant pain and potential for chest wall instability. Despite an emerging trend of surgical management of flail chest injuries, there are no studies examining the effect of rib fracture fixation on respiratory function. OBJECTIVES Using a novel full thorax human cadaveric breathing model, we sought to explore the effect of flail chest injury and su...

Displaced intra-articular calcaneal fractures Sanders 3 and 4 leaving a large bone void after reposition, continue to pose a therapeutic challenge. The purpose of this study was to determine the effects of open reduction and internal fixation (ORIF) combined with the injectable bone substitute CERAMENTTM|BONE VOID FILLER in patients with a bone gap > 2 cm after reduction. Twelve consecutive cas...

Tibial plateau fractures are complex injuries produced by high- or low-energy trauma. They principally affect young adults or the 'third age' population.These fractures usually have associated soft-tissue lesions that will affect their treatment. Sequential (staged) treatment (external fixation followed by definitive osteosynthesis) is recommended in more complex fracture patterns. But one shou...

Supracondylar fractures of humerus in children are the most common pediatric elbow fractures that account for about 70% of elbow fractures [1-3]. These fractures are divided into two types; extension (98%) and flexion (2%) type. Regarding to the amount of displacement, the extension type is divided by Gartland into type I (without displacement), type II (with displacement but intact posterior c...

Although distal radius fractures are in the centre of orthopedic surgeons' attention, the rate of unsatisfactory treatment results remains very high. This study evaluates the analytical approach to distal radius fracture treatment. We observed 59 patients divided into 4 groups according to a modified Fernandez classification, regarding the patomechanism of injury: 1. bending extraarticular frac...

We consider the magnetic field of a shell uniformly magnetized by an internal dipole that is subsequently removed. The Gauss coefficients of the resulting field are given in terms of the spherical harmonic coefficients of the shell thickness. This general solution can easily be reduced to common special cases by superposition. For a shell of constant thickness the external field vanishes (by Ru...

PURPOSE Network meta-analysis (NMA) is a comparatively new evidence-based technique in medical disciplines which compares the relative benefits associated with multiple interventions and obtains hierarchies of these interventions for various treatment options. We evaluated the effectiveness and safety of open reduction and internal fixation (ORIF), hemiarthroplasty (HA), reverse shoulder arthro...

The aim of this retrospective study was to investigate the frequency of persistent ulnar affection in patients who underwent open reduction and internal fixation (ORIF) of distal humeral fractures without ulnar nerve transposition or mobilisation. Eighty-two patients (53 women), mean age 62 years, were, at a mean of 48 months, reviewed through medical records and a subjective evaluation form co...

OBJECTIVES To investigate the differences of open reduction and internal fixation (ORIF) of complex AO Type C distal radius fractures between two different models of a single implant type. METHODS A total of 136 patients who received either a 2.4 mm (n = 61) or 3.5 mm (n = 75) distal radius locking compression plate (LCP DR) using a volar approach were followed over two years. The main outcom...

Mandibular fractures are frequently encountered in oral and maxillofacial surgery. Open reduction and internal fixation (ORIF) is one of the treatments of choice (1-3). Maxillomandibular fixation (MMF) is usually performed during surgery (2-5). Recently, an arch bar was reconsidered as a means of providing additional stability to internal fixation in anterior mandibular fractures (1, 5). The ar...
