INTRODUCTION Spinal epidural hematoma (SEH) is a rare disease that causes cord compression and neurologic deficit. Spontaneous SEH is related to minor trauma, bleeding disorders, and anticoagulant medications. Posttraumatic SEH has been associated with low-energy spine hyperextension injuries in patients with ankylosing spinal disorders such as ankylosing spondylitis and diffuse idiopathic skel...

Traditionally, flexor digitorum superficialis tenodesis has been recommended for surgical correction of posttraumatic proximal interphalangeal (PIP) joint hyperextension deformity resulting from recurrent volar plate (VP) disruption. In contrast, VP repair has been used sparingly to restore joint stability, because of concerns regarding excessive scarring, insufficient substance, and the often ...

The mechanism of injury in dorsal dislocations is usually PIP joint hyperextension combined with some degree of longitudinal compression, which frequently occurs in ball-handling sports if the tip of the digit is hit with the ball. In the majority of cases, dorsal dislocation produces a soft tissue or bone injury to the distal insertions of the three-dimensional ligament-box complex. The greate...

BACKGROUND Severe chest wall injuries are potentially life-threatening injuries which require a standardized multidisciplinary management strategy for prevention of posttraumatic complications and adverse outcome. CASE PRESENTATION We report the successful management of a 55-year old man who sustained a complete "bony disruption" of the thoracic cage secondary to an "all-terrain vehicle" roll...

Congenital knee dislocation is a rare anomaly associated with a variety of neuromuscular diseases and deformities. The etiology of this condition remains unclear, but it is usually associated with a variety of disorders, such as Larsen's syndrome, arthrogryposis, spondyloepiphyseal dysplasia, Ehlers-Danlos syndrome, Down syndrome, and Streeter's dysplasia. It is rarely an isolated entity, and 6...

Knee joint pain is a common symptom in obese individuals and walking is often prescribed as part of management programs. Past studies in obese individuals have focused on standing alignment and kinematics in the sagittal and coronal planes. Investigation of 6 degree-of-freedom (6DOF) knee joint kinematics during standing and gait is important to thoroughly understand knee function in obese indi...

Lower-limb exoskeletons have the potential to enhance rehabilitation [1], assist in walking with gait impairments [2], reduce the metabolic cost of normal [3] and load-bearing walking [4], improve stability [5] and probe interesting questions about human locomotion [6]. The ankle produces larger peak torques and performs more positive work than either the hip or the knee during locomotion [7], ...

OBJECTIVE According to the literature, 30-70% of cyclists suffer from cervical, dorsal, or lumbar back pain. This study was conducted to evaluate one of the possible causes of low back pain and to suggest a solution by appropriate adjustments to the bicycle. METHODS Serial fluoroscopic studies were performed while cyclists sat on different types of bicycle (sports, mountain, and city). Pelvic...

The purpose of this study was to dynamically examine various offset angles on the N-K table to determine which offset produces a torque pattern corresponding most closely to the isokinetic torque curve of the knee flexor musculature when tested at 60%. Subjects for the study were five college-age male volunteers (age=21.8+/-1.8 yrs, ht=181.9+/-4.3 cm, wt=88.4+/-12.6 kg). Mean peak isokinetic to...
