We undertook a retrospective comparative study
of all patients with an unstable slipped capital femoral epiphysis presenting
to a single centre between 1998 and 2011. There were 45 patients
(46 hips; mean age 12.6 years; 9 to 14); 16 hips underwent intracapsular
cuneiform osteotomy and 30 underwent pinning Pinning Non-emergency intracapsular osteotomy may have a protective effect
on the epiphyseal vasculature and should be undertaken with a delay
of at least two weeks. The place of emergency pinning Cite this article:
The dual-mobility cup seems to bring more stability without changing the gait pattern. Dislocations and instability are among the worst complications after THA in elderly patient. Dual mobility cups seem to lower these risks. To our knowledge no study performed a gait analysis of dual cup in this group.Summary Statment
Introduction
Mobile-bearing knee prostheses have been designed in order to provide less constrained knee kinematics compared to fixed-bearing prosthesis. Currently, there is no evidence to confirm the superiority of either of the two implants with regard to walking performances. It has been shown that subjective outcome scores correlate poorly with real walking performance and it has been recommended to obtain an additional assessment of walking ability with objective gait analysis. We assessed recovery after total knee arthroplasty (TKA) with mobile- and fixed-bearing between patients during the first postoperative year, and at 5 years follow-up, using a new objective method to measure gait parameters in real life conditions.INTRODUCTION
OBJECTIVES
Debate remains over the optimal treatment for severe unstable SCFE. AVN is the principle problem; current thinking suggests this can be minimized by emergent reduction and fixation within 24 hours. If emergent treatment is not possible, open osteotomy with a variable delay of 10–21 days has been advocated. We present our experience of delayed intracapsular cuneiform osteotomy (ICO) SCFE cases were identified through ICD-10 coding and theatre records. Unstable slips were identified and reviewed retrospectively. When ICO was performed, the hip was accessed via anterior approach without hip dislocation. A cuneiform shortening osteotomy of the neck with physeal excision was undertaken. The epiphysis was carefully reduced and stabilized with a single screw.Aim
Methods
This study compared the outcome of total knee
replacement (TKR) in adult patients with fixed- and mobile-bearing prostheses
during the first post-operative year and at five years’ follow-up,
using gait parameters as a new objective measure. This double-blind
randomised controlled clinical trial included 55 patients with mobile-bearing (n
= 26) and fixed-bearing (n = 29) prostheses of the same design,
evaluated pre-operatively and post-operatively at six weeks, three
months, six months, one year and five years. Each participant undertook
two walking trials of 30 m and completed the EuroQol questionnaire,
Western Ontario and McMaster Universities osteoarthritis index,
Knee Society score, and visual analogue scales for pain and stiffness.
Gait analysis was performed using five miniature angular rate sensors
mounted on the trunk (sacrum), each thigh and calf. The study population
was divided into two groups according to age (≤ 70 years Improvements in most gait parameters at five years’ follow-up
were greater for fixed-bearing TKRs in older patients (>
70 years),
and greater for mobile-bearing TKRs in younger patients (≤ 70 years).
These findings should be confirmed by an extended age controlled
study, as the ideal choice of prosthesis might depend on the age
of the patient at the time of surgery.
Ten patients were studied using an ambulatory gait device (Physilog®). Each participant was asked to perform two walking trials of 30m long at 3 different speeds and to complete an EQ-5D questionnaire, a WOMAC and Knee Society Score. Lower limbs rotations were measured by four miniature angular rate sensors mounted respectively, on each shank and thigh. The outcomes of the eight patients undergoing total knee arthroplasty, recorded pre-operatively and post-operatively at 6 weeks, 3 months, 6 months and 1 year were compared to 2 age-matched healthy subjects.
