Due to the elbow joint's complex functional anatomy, the multifragmentary nature of many fractures and concomitant destabilizing associated injuries, dislocated fractures of the radial head and neck still present a serious challenge for the orthopedic surgeon. Thorough knowledge of the elbow's anatomy and biomechanics is essential to analyze and understand the injury and plan its treatment. The...

of diaphyseal long bone fractures. Interlocking nails have transverse cannulations that accommodate transcortical screws, allowing surgeons to firmly fix the rod within the medullary canal, thereby effectively neutralizing bending, rotational, and axial forces that act on fractures. Interlocking nails have become increasingly To counter axial and rotational forces, intramedullary nails were dev...

Pediatric manual wheelchair users (MWU) require high joint demands on their upper extremity (UE) during wheelchair mobility, leading them to be at risk of developing pain and pathology. Studies have examined UE biomechanics during wheelchair mobility in the adult population; however, current methods for evaluating UE joint dynamics of pediatric MWU are limited. An inverse dynamics model is prop...

BACKGROUND Work-related injuries of the shoulder complex represent a challenge for clinicians because of the large variety of clinical entities involved and the broad anatomic structures that can be affected. Furthermore, commonly performed orthopedic tests have demonstrated limited accuracy for diagnosing the injury despite considerable research efforts. The aim of this study protocol is there...

Patellofemoral pain (PFP) is a common knee disorder in orthopedic clinics. In the last decade, several investigations have considered the role of proximal factors in addition to local and distal factors in development of PFP. There is a hypothesis which suggests that impaired neuromuscular control and altered hip joint kinematic affect tibiofemoral and patellofemoral biomechanics. Hence, PFP ma...

One section of the Orthopaedic In-Training Examination (OITE) assesses knowledge about hip reconstruction. In the investigation reported here, we examined OITE hip reconstruction questions and sought to identify which literature can be recommended as study aids for this section of the test. All hip reconstruction questions on the OITE from 2002 to 2006 were characterized according to diagnosis ...
