Dynamic knee valgus during landings is associated with an increased risk of non-contact anterior cruciate ligament (ACL) injury. In addition, the impact on the body during landings must be attenuated in the lower extremity joints. The purpose of this study was to investigate landing biomechanics during landing with dynamic knee valgus by measuring the vertical ground reaction force (vGRF) and a...

INTRODUCTION: Hallux valgus (bunions) are prominent and often inflamed metatarsal heads and overlying bursae. They are associated with valgus deviation of the great toe which moves towards the second toe. Hallux valgus is found in at least 2% of children aged 9 to 10 years, and almost half of adults, with greater prevalence in women. METHODS AND OUTCOMES: We conducted a systematic review and ai...

BACKGROUND Currently, the metatarsophalangeal angle (hallux valgus angle) is measured based on radiographic images. However, using X-ray examinations for epidemiological or screening purposes would be unethical, especially in children. For this reason it is discussed to measure the hallux valgus angle of the margo medialis pedis (medial border of the foot) documented on foot outline drawings or...

background:   hallux valgus deformity is a common chronic problem in middle age and elderly. different surgical procedures have been introduced so far with their proposed indications for each. this study aimed to compare three   current procedures namely chevron osteotomy, scarf osteotomy and mcbride technique.     methods:   in this study, 44 patients were included from 2010 to 2013. all patie...

Phase noise is a property of an oscillator that can extend in magnitude from the carrier of several volts down to a mere nano-volt far from the carrier. In many cases the lowest noise OCXOs, SAWs and other specialty oscillators have carrier to noise ratios in excess of -180 dBc/√Hz. The noise level of these oscillators often extends below that of even the mixers and low noise amplifiers at base...

Correction osteotomies of the first metatarsal are common surgical approaches in treating hallux valgus deformities whereas the Scarf osteotomy has gained popularity. The purpose of this study was to analyze short- and mid-term results in hallux valgus patients who underwent a Scarf osteotomy. The subjective and radiological outcome of 131 Scarf osteotomies (106 hallux valgus patients, mean age...

Total knee arthroplasty following valgus deformity is a challenging procedure due to the unique set of problems that must be addressed. The aim of this study is to determine, with a finite element analysis, the load distribution for an inclined valgus prosthetic balanced knee and to compare these results with those of a prosthetic balanced knee with an uninclined interline. Computational simula...

The painful pes planovalgus foot type includes a range of deformities. Causes for the symptomatic pes valgus deformity include posterior tibial tendon dysfunction, subluxation of the talus, triceps surae or isolated gastrocnemius equinus, traumatic tendon rupture, ligament laxity, and various neuromuscular imbalances. Detailed discussion of the anatomy and physiology of the symptomatic pes plan...

OBJECTIVES Malalignment of the tibial component could influence the long-term survival of a total knee arthroplasty (TKA). The object of this study was to investigate the biomechanical effect of varus and valgus malalignment on the tibial component under stance-phase gait cycle loading conditions. METHODS Validated finite element models for varus and valgus malalignment by 3° and 5° were deve...
