Mono-articular idiopathic heterotopic ossification in a Coronavirus infected patient admitted in the intensive care unit.

Heterotopic ossification (HO) designates a bone tissue formation within an atypical anatomical location and is commonly diagnosed in patients whom have suffered major traumas. The following case report presents a non-traumatic source of HO. A causality is deduced between the HO formation and an important inflammatory reaction originating from a Coronavirus infection.

Radiolucent lines around knee arthroplasty components : a narrative review.

Aseptic loosening of total knee arthroplasty (TKA) components is one of the frequent reasons for early revision together with infection and instability. Aseptic loosening is usually preceded by the observation of radiolucent lines (RLL) on radiographs. Radiolucent lines have conventionally been considered a sign of osteolysis due to particles disease of either polyethylene or cement wear.

Effect of the neuro-orthopedic surgery for spastic equinovarus foot after stroke: a prospective longitudinal study based on a goal-centered approach.

Background: Neuro-orthopedic surgery is recognized as an effective treatment to improve walking capacity in case of spastic equinovarus foot. However, the effect of surgery on the 3 domains of the International Classification of Functioning, Disability and Health (ICF) has never been studied.

Aim: The aim of this study was to assess the efficacy of the neuro-orthopedic surgery for spastic equinovarus foot after stroke based on a goal-centered approach and on the 3 domains of the International Classification of Functioning, Disability and Health (ICF).

Assessment and treatment of spastic equinovarus foot after stroke: Guidance from the Mont-Godinne interdisciplinary group.

Objective: To present interdisciplinary practical guidance for the assessment and treatment of spastic equinovarus foot after stroke.

Results: Clinical examination and diagnostic nerve block with anaesthetics determine the relative role of the factors leading to spastic equinovarus foot after stroke: calf spasticity, triceps surae - Achilles tendon complex shortening and dorsiflexor muscles weakness and/or imbalance. Diagnostic nerve block is a mandatory step in determining the cause(s) of, and the most appropriate treatment(s) for, spastic equinovarus foot.

Changes in anteroposterior stability and proprioception after different types of knee arthroplasty.

Purpose: To compare different types of knee arthroplasty, in selected patients with a knee score above 80 points, for their post-operative changes in anteroposterior (AP) laxity and proprioception.

Methods: Four groups of each ten patients were tested for AP translation after different types of arthroplasty with a KT-1000 device at 30°, 60° and 90° of flexion. Proprioception of the joint was evaluated by joint position sense with three different tests.
