the distally based sural fasciocutaneous flap has become a main part of the reconstruction of the lower leg, heel and foot. however, perfusion problems and venous congestion have been reported. over the past decade, several flap modifications have been reported to improve flap viability and to solve a myriad of reconstructive needs. the purpose of this paper is to describe our experience in har...

In this article, architectures for interplanetary communications that feature the use of a data relay are investigated. considered “two-leg” architecture, spacecraft orbiting Earth, or in orbit at Lagrange point, receives from deep-space probe (leg-1) and relays them toward ground (leg-2). Different wireless technologies link, namely, radio frequencies above Ka band optical frequencies, conside...

Continuous measurements of anterior-posterior leg position recorded from stick insects walking on a wheel were tested for relationships among spatial and temporal parameters of leg coordination. This analysis revealed that the protraction of middle and rear legs is guided by the ipsilateral front and middle legs respectively. Protraction endpoint for each rear leg shows a significant positive c...

The anterior cruciate ligament (ACL) injury is a common occurrence in sports requiring stop-jump tasks. Single- and double-leg stop-jump techniques are frequently executed in sports. The higher risk of ACL injury in single-leg drop landing task compared to a double-leg drop landing task has been identified. However the injury bias between single- and double-leg landing techniques has not been i...

abstract the leg is a complex district with functions of weightbearing support, stability, and motility. the management of extensive and complex defects is more challenging and often results in leg amputation or shortening. leg amputation is a severe mutilation that alters the patient’s work and social life by limiting ambulation and self-sufficiency. during a 3 years period we treated four pat...

background: high tibia osteotomy (hto) is a common surgical operation for correction of genu varum deformity. in some patients,there are concurrent tibia vara and genu varum (bow leg). this study aimed to consider the possibility of better correction of bow leg deformity after double level tibial osteotomy (dlto). materials and methods: a case series of 10 patients of genu varum in addition to ...

CONTEXT Since decades leg dominance is suggested to be important in rehabilitation and return to play in athletes with anterior cruciate ligament injuries. However, an ideal method to determine leg dominance in relation to task performance is still lacking. OBJECTIVE To test the agreement between self-reported and observed leg dominance in bilateral mobilizing and unilateral stabilizing tasks...

Leg-length discrepancy greater than 2 to 2.5 cm can potentially have an adverse effect on our walking and standing mechanisms and requires proper correction involving surgical treatment. However, for minor leg-length discrepancy in childhood, decision making for the indications for and timing of epiphysiodesis is difficult because of unpredictable final discrepancy. The purpose of this study wa...

background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...
