Post-burn contracture and deformities of the foot and ankle joint with respect to other localizations account for 3.5-5% of cases. Functional disturbances of the foot and ankle joint affect the functioning of the entire lower joint, its statics, and the patient's gait and bearing, and can even lead to distorted pelvis, curvature of the spine, and other disturbances. Between 1990 and 2002 we tre...

In this review paper three models to calculate mechanical work, the pattern of joint power during steady-state cycling and some theories regarding energy transfer through the joints and coordinative pattern analysis by joint mechanical work distribution will be briefly presented. Finally, there will be a report on the effects of workload, pedaling cadence and saddle height management on joint m...

The formation of mature lamellar bone at an ectopic site in the body is called heterotopic ossification. We report the case of a 28 year-old patient with heterotopic ossification (HO) in the left crus. He complained of difficulties with walking and limited ROM of the ankle joint. At surgery, an incision was made through the center of the HO focus, which was palpable. No change in ROM of the ank...

We have devised a medial peri-articular osteotomy, the distal tibial oblique osteotomy (DTOO), and have used this technique since 1994 for ankle osteoarthritis of advanced and late stages associated with varus inclination. This report describes the surgical technique and its applicability. DTOO can be used for cases of varus ankle osteoarthritis with a range of the ankle joint movement of at le...

The history of arthroscopy begins in 1918 when Takagi performed a knee arthroscopy in a cadaver. Due to its narrow joint space, the ankle joint was not considered suitable for arthro‐ scopy in those days. Despite this, in 1939, Takagi described an arthroscopic technique for the ankle joint in a Japanese Orthopaedic Association Journal (Takagi 1939). Watanabe describes in 1972 the anteromedial, ...

The objectives of this study were to characterize the active and passive contributions to joint kinetics during walking in healthy young and older adults, and assess whether isokinetic ankle strength is associated with ankle power output during walking. Twenty healthy young (18-35 years) and 20 healthy older (65-85 years) adults participated in this study. We measured subject-specific passive-e...

An optimal control system that enables a subject to stand without hand support in the sagittal plane was designed. The subject was considered as a double inverted pendulum structure with a voluntarily controlled degree of freedom in the upper trunk and artificially controlled degree of freedom in the ankle joints. The control system design was based on a minimization of cost function that estim...

INTRODUCTION The aim of the study was to assess the influence of a supervised programme of exercises on ankle joint mobility in patients with venous leg ulcerations. MATERIAL AND METHODS The study was carried out between 2008 and 2009 at the Venous Ulcer Treatment Outpatient Clinic and Clinic of General and Vascular Surgery of the Dr Jan Biziel University Hospital no. 2 in Bydgoszcz. It was a...
