The aim of this study was to evaluate the correlation between
Salter’s criteria and Kalamchi’s classification of avascular necrosis
in patients treated for developmental dysphasia of the hip (DDH). The study involved a retrospective analysis of 123 patients (123
hips) with DDH treated by operative and non-operative reduction
before the age of two years, with a minimum follow-up of ten years.
Salter’s criteria (S1 to S4) were determined from radiographs obtained
at one to two years post-reduction, whilst the Kalamchi grade was determined
from radiographs obtained at ten or more years of age. Early post-reduction
radiographs were also used to evaluate the centre-head distance
discrepancy (CHDD) and the occurrence of a dome-shaped deformity
of the proximal femoral metaphysis (D-shaped metaphysis). The prognosis was described as good (Kalamchi grade K0 or KI),
fair (Kalamchi grade KII) or poor (Kalamchi grade KIII or KIV) for
analysis and correlation with the early Salter criteria, CHDD and
D-shaped metaphysis.Aims
Patients and Methods
Venous thromboembolisms are serious complications of arthroplasty of the lower extremities. Although early ambulation and active leg exercise is recommended, postoperative patients with surgical pain have difficulty in moving their legs. Therefore, we developed a novel leg exercise apparatus (LEX) to facilitate active leg movement even during the early postoperative period (Fig 1). LEX is a portable apparatus that allows patients to actively move their legs while in the supine position. LEX enables dorsiflexion, plantar flexion, combined eversion and inversion of the ankle, and multi-joint movement of the leg. To describe how LEX facilitates active movement of the leg and thereby increases venous flow in the lower extremities.Background
