BACKGROUND Patella dislocation and re-dislocation are common diseases. Although patella dislocation is frequent, it always poses a challenge concerning diagnostics and therapy. Mixed forms of pathological disorder in the patellofemoral joint make the analysis of the malalignment and the choice of the correct treatment more difficult. MATERIAL AND METHODS By reviewing the available literature ...

Long-term spinal cord injury (SCI) profoundly alters skeletal structure and function. In this study, the biomechanical properties of tibias from persons with SCI and from individuals closely matched in age and size but without SCI were quantified at both the structural and material levels. Nondestructive torsion tests were performed to determine apparent shear moduli for the tibia. The cortical...

Blount's disease is commonly attributed to an intrinsic, idiopathic defect in the posteromedial proximal tibial physis resulting in progressive bowing of the leg, intoeing, and lateral knee thrust. Treatment has historically included bracing, physeal stapling, or corrective osteotomy, and was determined primarily by age at presentation. As we feel the pathology is not necessarily age dependent,...

BACKGROUND Torsional distortion causes numerous musculoskeletal pathologies. Effective treatment allows restoring limb function and return to sport activity. Objectives was to assess the sport activity in patients with derotational corticotomies using the Ilizarov method. METHODS It was case series retrospective study. The study examined 56 patients. The control group consisted of 54 patients...

Introduction: Nature produces amazingly varied geometrical patterns. In particular, logarithmic spirals are abundantly observed in nature. Gastropods/cephalopods (such as nautilus, cowie, grove snail, thatcher, etc.) in the mollusca phylum have spiral shells, mostly exhibiting logarithmic spirals vividly. Spider webs show a similar pattern. The low-pressure area over Iceland and the Whirlpool G...

Background: Left ventricular torsion is one of the most important biomechanical parameters of heart that routinely is measured in short axis view.  A review of the literature has indicated that assessment of left ventricular torsion in short axis view has some limitations. In the present study, we evaluated whether torsion angle assessment in long axis view can be used as a diagnostic biomechan...

abstract   background: the tibial diaphyseal fractures are the most common type of long bone fractures encountered by most orthopedic surgeons. in accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia fractures have the second incidence of all tibia fractures after the middle tibia fractures. the purpose of the study was to assess the co...

Background: Blount disease is frequently associated with deformities that may not be adequately corrected by a single metaphyseal osteotomy. This study evaluated the outcome of a combined metaphyseal and epiphyseal osteotomy in severe cases. Methods: We prospectively evaluated the outcome of combining the antero-posterior inverted-U metaphyseal osteotomy with a medial open-wedge hemi-epiphyseal...

The testicular torsion which is typically seen in prepuberty is very rare in the early neonatal period; prenatal diagnosis is difficult. Herein, we report a five day-old male neonate with swelling and erythema of the right scrotum.  Following Doppler ultrasound suggestive of testicular torsion, surgical exploration was undertaken. There was gangrene of the right testis with discoloration and ne...
