Legg-Calve-Perthes (Perthes Disease) was first recognised by three physicians, Arthur Legg (1874–1939), Jacqui Calve (1875–1954) and George Perthes (1869 – 1927) in 1910. Perthes disease is a rare childhood condition that affects the hip. It occurs when the blood supply to the femoral head is disrupted. Without this blood supply, the bone cells die and avascular necrosis can occur. The Herring classification is used to diagnose the stages of Perthes Disease. It is an important prognostic factor. There are three classifications, Herring A, B and C. Herring A has no involvement of the lateral pillar with no density changes noted on x-ray. Herring B has at least 50% of the lateral pillar height maintained on x-ray. Herring C has less than 50% of the lateral pillar height on x-ray (Herring et al, 1992). Children with Perthes disease require specialist Limb Reconstruction team throughout their treatment journey, this includes Orthopaedic surgery and therapy (Physiotherapy and Occupational Therapy). The National Limb Reconstruction Therapy Team is based at the National Orthopaedic Hospital, Cappagh. The therapy team consists of 1 Clinical Specialist Physiotherapist, 1 Senior Physiotherapist and 1 Senior Occupational Therapist who provide input to this cohort. This study aims to analyse the importance of a comprehensive pre-operative assessment by the therapy team (Physiotherapist and Occupational Therapist) to maximise patient outcomes post operatively. This is a quantitative research study conducted by the National Limb Reconstructive Therapy Service of the National Orthopaedic Hospital in Cappagh, Dublin. The inclusion criteria for this study consisted of:
Age – Patient must be part of the Paediatric Service, i.e., under the age of 16. Diagnosis – Patient must have a diagnosis of Perthes Disease with a Herring Classification documented. Application of a Hip Distractor Frame formed part of the patient's surgical management. Surgery was completed by Mr Connor Green. Surgery was completed between January 2021 and December 2022. Patient were required to have their external hip distractor frame removed by December 2022. Exclusion Criteria: Those not meeting the above inclusion criteria. Following the inclusion criteria, a number of cases were identified of which 10 cases were selected at random. A retrospective analysis of these samples was completed. The medical charts were reviewed as well as patient electronic healthcare records. Microsoft Excel was utilised to analyse the data and capture results.Introduction
Methodology
Hip arthrodiastasis for paediatric hip conditions such as Perthes disease is growing in popularity. Intended merits include halting the collapse of the femoral head and maintaining sphericity by minimising the joint reaction force. This can also be applied to protecting hip reconstruction following treatment of hip dysplasia. Our aim was to assess functional outcomes and complications in a cohort of paediatric patients. A retrospective single-surgeon cohort study was performed in a University teaching hospital from 2018–2021. Follow-up was performed via telephone interview and review of patient records. Complications, time in frame and functional scores using the WOMAC hip score were recorded.Introduction
