abstract introduction: patellofemoral pain syndrome is a common problem in the knee joint, which comprise 20 to 40 percent of knee pain and 10 to 20 percent of subjects admitted in physiotherapy clinics. the aim of this study was to investigate the relationship between navicular drop and tibia torsion in active girl students with and without patellofemoral pain syndrome. materials and methods: ...

Bending, in addition to compression, is recognized to be a common loading pattern in long bones in animals. However, due to the technical difficulty of measuring bone deformation in humans, our current understanding of bone loading patterns in humans is very limited. In the present study, we hypothesized that bending and torsion are important loading regimes in the human tibia. In vivo tibia se...

Background and purpose - Coronal and sagittal plane long bone deformities can be corrected with guided growth, whereas transverse plane rotational deformities require osteotomy and internal or external fixation. We investigated whether rotational changes can be introduced with the plating technique. Methods - 45 rabbits (6 weeks old) were divided into 3 groups. The unoperated right tibia was us...

There is some uncertainty about rotational deformity of the lower leg in club feet. Many standard textbooks and some monographs describe medial tibial torsion as occurring constantly or often (McMurray 1943, Turek 1959, Campbell 1963, Kite 1964, Le Noir 1966). Mercer and Duthie (1964) mentioned medial torsion but considered it rare. Ober (1920) and Ferguson (1957) noted that the fibular malleol...

ABSTRACT Tibial torsion, the twisting of the tibia about its long axis, can affect rotational positioning in total knee replacement. This angle varies depending on the ethnicity of the subject. There are no published studies to date to determine the tibial torsion among Filipinos. In this study, 28 cadaveric limbs were examined. Our results show that the average tibial torsion among adult Filip...

Tibial torsion, twisting of the tibia about its longitudinal axis, varies during development and early childhood. Knowledge of the normal range of tibial torsion at various ages and its accurate clinical measurement is important in the assessment of the extent of a torsional deformity. To evaluate tibial torsion a reliable technique for its measurement in vivo is therefore required. The aim of ...

We reviewed 20 patients with spina bifida who had had surgical management of tibial torsion. Eight had had bilateral procedures and 12 a unilateral procedure, giving a total of 28 limbs for analysis. We performed closed osteoclasis on seven limbs and tibial osteotomy on 21. In the closed osteoclasis group six limbs (85%) had a good result after an average follow-up of nine years (2 to 22). All ...

Following the acceptance for publication of the article by Hazlewood et al. in a recent issue of Gait & Posture we were invited by the Editor in Chief to comment on the challenging issue of measuring tibial torsion [1]. Tibial torsion describes the axial or transverse plane alignment of the shank segment of the lower extremity. In utero, lower extremity limb bud formation occurs during the 4th ...

OBJECTIVES Osteogenesis imperfecta (OI) frequently leads to long-bone bowing requiring a surgical intervention in severe cases to avoid subsequent fractures. However, there are no objective criteria to decide when to perform such intervention. The objective is to develop a finite element model to predict the risk of tibial fracture associated with tibia deformity in patients with OI. METHODS ...

The aim of this study was to quantify the effect of torsion deformity on the lower limb kinetics during the loading response phase of gait. A total of 24 subjects: 6 end-staged medial knee OA with torsion deformity (TKO), 8 without torsion deformity (KOA), and 10 controls (CON) were imaged using computed tomography (CT). Internal moment of support and sagittal hip, knee and ankle joint moments ...
