The use of total hip arthroplasty in adolescents for end-stage degenerative hip disease is controversial with few reported outcomes in the literature. The purpose of the study was to report the outcomes of total hip arthroplasty in a cohort of adolescents managed by a multidisciplinary team of paediatric and adult orthopaedic surgeons from a single centre.

A multidisciplinary clinic consisting of paediatric and adult hip surgeons was established in 2013 to identify, treat and prospectively follow adolescents who would potentially beneift from a total hip arthoplasty. To date 29 consecutive adolescent patients (20 female, 9 male, 32 hips) with end stage degenerative hip disease have undergone cementless primary total hip arthroplasty. Mean age at decision to treat was 15.7 years (age 11.4–18.5). Ten different underlying paediatric specific pathologies were documented including DDH, cerebral palsy, JIA, skeletal dysplasias, SCFE and idiopathic chondrolysis. Three patients had bilateral staged procedures. Clinical baseline and outcomes were measured using Oxford Hip Score (OHS), WOMAC score and ASKp scores. Radiographic follow-up was conducted at 6 weeks, 6 months and yearly thereafter. Post-operative complications were recorded.

Twenty-five hips were eligible for minimum 2-year follow-up scoring at a mean 2.7 years (2.0–3.6 years). No intraoperative complications occurred. One case of recalcitrant postoperative psoas tendonitis occured. OHS improved from 25 (7–43) to 41 (23–48). WOMAC improved from 48 (12–8) to 12 (1–44), and ASKp improved from 78% (33–98%) to 93% (73–100%). Radiographic review revealed acceptable alignment of all components with no signs of loosening or wear. No revision of components was required. One patient died at 6 months post op from an unrelated condition.

The early term results of total hip arthroplasty in adolescents from our multidisciplinary program are encouraging. Improvements in quality of life to normal values were seen as were hip scores consistent with satisfactory joint function. Depite the range of complex and varied causes of arthritis seen in this population the establishment of combined paediatric and adult orthopaedic surgical teams appears to be a successful model to manage end-stage degenerative hip disease in adolescents.

Introduction

Numerous musculoskeletal and systemic conditions may affect the hips of paediatric patients. While the large majority of patients go on to achieve positive outcomes, a small number will progress to end stage arthropathy with significant functional impairment. Management options have been significantly limited for this population. An adolescent hip arthroplasty program was developed with the aim to improve symptoms and quality of life for patients with pain and disability refractory to joint preserving management strategies.

Purpose

To compare the early medial open approach (MO) with the anterior approach (AO) performed after the appearance of the ossific nucleus for DDH that has failed closed reduction or presented late.

Long-term prospective RCT comparing hemiarthroplasty (HEMI) and total hip arthroplasty (THA) for the treatment of intracapsular neck of femur fracture.

81 previously mobile, independent, orientated patients were randomised to receive THA or HEMI after sustaining a displaced neck of femur fracture. Patients were followed up with radiographs, Oxford hip score (OHS), SF-36 scores and their walking distance.

At a mean follow up of 8.7 years, overall mortality following THA was 32.5% compared to 51.2% following HEMI (p=0.09). Following THA, patients died after a mean of 63.6 months compared to 45 months following HEMI (p=0.093). Patients with THA walked further and had better physical function. No HEMIs dislocated but three (7.5%) THAs did. Four (9.8%) HEMI patients were revised to THA, but only one (2.5%) THA required revision. All surviving HEMI patients had acetabular erosion and all surviving THA patients had wear of the cemented polyethylene cup.

Patients with THA have better function in the medium-term and survive longer.

Introduction: We report on the long-term follow up of a previously published randomised controlled trial comparing Hemiarthroplasty (HEMI) and total hip arthroplasty (THA) for the treatment of intracapsular fracture neck of femur.

Methods: In this prospectively randomized study, 81 patients who had been mobile and lived independently and who sustained a displaced fracture of the femoral neck were randomized to receive either a fixed acetabular component THA or HEMI. The mean age of the study group was 75 years at fracture. All patients received the same cemented collarless tapered femoral stem and all procedures were performed through a transgluteal approach. Patients were followed up with radiographs, Oxford hip score (OHS), SF-36, Euroqol and their walking distance.

Results: At a mean follow-up of 8.6 years (7.18 to 10.27), 19 HEMI patients and 27 THA were alive (p=0.042). The mean walking distance of patients after HEMI was 600m and the OHS 21. After THA, the mean walking distance was 1200m and the OHS was 22. Both groups had a deterioration of their OHS over time. There were no significant differences between the groups with respect to both physical and mental component SF-36 scores and Euroqol visual analogue scores.

Of the survivors four of the HEMI group were revised to total hip arthroplasty. One patient had been revised in the THA group. Radiographically six of seven patients in the HEMI group had evidence of acetabular erosion and 13 of 15 patients in the THA group had a lucency around their acetabular component.

Discussion: Patients with THA walked further and survived longer. After a mean of nine years follow up there was no difference with respect to function as measured by OHS, Euroqol and SF-36 scores.

The results of a functional, clinical and radiological study of 30 children (60 hips) with whole body cerebral palsy are presented with a mean follow-up of ten years.

Bilateral simultaneous combined soft-tissue and bony surgery was performed at a mean age of 7.7 years (3.1–12.2).

Evaluation involved interviews with patient/carers and clinical examination.

Plain radiographs of the pelvis assessed migration percentage and centre-edge angle.

Twenty two patients were recalled. Five had died of unrelated causes and three were lost to follow-up.

Pain was uncommon, present in 1 patient (4.5%). Improved handling was reported in 18 of 22 patients (82%). Carer handling problems were attributed to growth of the patients. All patients/carers considered the procedure worthwhile.

The range of hip movements improved, with a mean windsweep index of 36 (50 pre-operatively)

Radiological containment improved, with mean migration percentage of 20 degrees (50 preoperatively) and mean centre-edge angle of 29 degrees (−5 preoperatively) No statistical difference was noted between the three year and ten year follow-up results demonstrating maintained clinical and radiological outcome improvement.

In conclusion, we consider that bilateral simultaneous combined hip reconstruction in whole body cerebral palsy provides painless, mobile and anatomically competent hips in the long term.

Purpose of study: To assess functional, clinical and radiological outcomes of 30 children (60 hips) with whole body cerebral palsy with a mean follow-up of ten years.

Method: Bilateral simultaneous combined soft-tissue and bony hip surgery was performed at a mean age of 7.7 years (3.1–12.2). Evaluation at ten years involved interviews with patient/carers and clinical examination. Plane radiographs of the pelvis assessed migration percentage and centre-edge angle.

Results: Twenty two patients were recalled. Five had died of unrelated causes and three were lost to follow-up. Pain was present in only 1 patient (4.5%). Improved handling was reported in 18 of 22 patients (82%). Carer handling problems were attributed to growth of the patients. All patients/carers considered the procedure worthwhile. The range of hip movements improved, with a mean windsweep index of 36 (50 pre-operatively) Radiological containment improved, with mean migration percentage of 20 degrees (50 preoperatively) and mean centre-edge angle of 29 degrees (−5 preoperatively) No statistical difference was noted between the three year and ten year follow-up results, demonstrating sustained improvement in the clinical and radiological outcome.

Conclusions: Bilateral simultaneous combined hip reconstruction in whole body cerebral palsy provides painless, mobile and anatomically competent hips in the longer term.

The majority of the available literature considers the short term outcome of surgical reconstruction of the hips in this condition. This paper demonstrates that the initial improvements in structure and function are maintained in the longer term.

Arthroplasty is the most effective management of displaced intracapsular femoral neck fracture. Hemiarthroplasty (HEMI) is associated with acetabular erosion and loosening in mobile patients and total hip arthroplasty (THA) with instability.

We sought to establish whether HEMI or THA gave better results in independent mobile patients with displaced intracapsular femoral neck fracture.

Eighty-two patients were randomised into two groups. One arm received a modular HEMI, the second a THA using the same femoral stem. Patients were followed for a mean of three years after surgery.

After HEMI, eight patients died, two were revised to THA and there is intention to revise three. One patient had a periprosthetic fracture. Mean walking distance was 1.08 miles and Oxford Hip Score (OHS) 22.5. Twenty patients (64.5% of survivors) had radiological evidence of acetabular erosion.

After THA, four patients died, three dislocated, one required revision. Mean walking distance was 2.23 miles and OHS was 18.8.

HEMI is associated with a higher rate of revision than THA and potential revision because of acetabular erosion. THA after three years displayed superior walking distances (p=0.039) and lower OHS (p=0.033).

THA is a preferable option to HEMI in independent mobile elderly patients with displaced intracapsular femoral neck fracture.

The cost of claims for personal injury after whiplash injury costs the economy of the United Kingdom some £3 billion per year. The majority of vehicle occupants subjected to rear-end shunt either suffer no effects or make a complete recovery however a minority suffer adverse psychological and social consequences which may be largely unrelated to the severity of the initial physical insult.

The early psychological reactions include feelings of being shocked, frightened and angry which are related to the victim’s subjective perception of accident severity. During the days after many victims continue to experience anxiety and distress manifest in physical, emotional, cognitive and social complaints – which may be severe enough to constitute the diagnosis of acute stress disorder which has a high risk of subsequent PTSD (Post – Traumatic Stress Disorder)

Ongoing apparently disproportionate disability can take a number of forms but is usually an unconscious process resulting from the interaction of physical, psychological and social variables.

The risk factors for a poor psychological outcome include pre-accident characteristics, the nature of the accident, beliefs favouring chronicity, quality of care along with independent post-accident events and in many cases the effect of litigation.
