OSTEOGENESIS IMPERFECTA Management of fractures and nursing care Christian Micallef 11th April 2012
Case Presentation
Joey, a six year old boy with Osteogenesis Imperfecta Type VIII - presented to the emergency department, accompanied by his mother, after hitting his left thigh off a table while driving his electric wheelchair.
Main Aims To get a better understanding of: Osteogenesis Imperfecta (O.I.) as a condition Management of fractures in children with O.I. Nursing care of the child with O.I. and his/her family
Definition
O.I. comprises a heterogenous group of genetic disorders characterized by increased bone fragility, low bone mass, and susceptibility to bone fractures with variable severity (Forin, 2010; National Centre for Medical Genetics, 2012) UK: 1:15,000 (Brittle Bone Society, 2012)
History
1000BC – Egyptian mummy 9th Century Denmark – Ivan the Boneless 1600s – Medical Literature (case studies) 1849 – Termed “Osteogenesis Imperfecta” 1906 – Divided into “congenita” and tarda” 1918 – inherited syndrome (fragile bones, blue sclera and early deafness) 1970s – Classification System Type I, II, III and IV (David Sillence) Present – addition of Type V, VI, VII and VIII (Glorieux and Rauch)
Classification
Type I – mild Type II – perinatal lethal Type III – progressive deforming Type IV – moderate severe Type V – similar to Type IV (with dominant inheritance pattern) Type VI – similar to Type IV (characteristic mineralization defect seen in biopsied bone) Type VII and VIII – recessive types (recently identified, less than 10% of all cases)
O.I. Type VIII
O.I. – mutation in either one of the type 1 collagen genes and inherited in an autosomal dominant fashion Unique loss of function mutation c.232delC in the LEPRE1/p3H1 gene was identified in the Irish Traveller population (Cabra et al, 2007) Children from the Travelling community with Type VIII O.I. are homozygous for this deletion (National Centre for Medical Genetics, 2012)
O.I. Groups
Ireland - Facebook Page “Osteogenesis Imperfecta Ireland” UK – “Brittle Bone Society” (founded in 1968 in Dundee) USA – “Osteogenesis Imperfecta Foundation” (established in 1970)
The Nursing Process
APIE - created by Ida Jean Orlando (1958) The Modified Nursing Process: Assessment Diagnosis Plan Implementation Evaluation
Assessment
Triage – use of structured approach (ALSG, 2011) ABC – normal D – electric wheelchair to mobilize (restricted to same) E – Pain (Score of 3) to left thigh area, slight swelling noted – no analgesia given prior to attendance
Diagnosis
Nursing Diagnosis – Possible fracture to the left femur
Plan
Comfort – Pain Management (Joey refused analgesia at triage) Triaged at Category 2 Seen by one of the a&e consultants: Possible fractured femur (x-ray) If fractured, provide treatment as required Nursing Care and Discharge Planning
Intervention
X-Ray – undisplaced fracture of the left femoral shaft Review by orthopaedic surgeons – surgery not advisable – treated with a single leg spica (works well in 88-95% of stable fractures) Kanlic and Cruz (2007) in the community – already established Follow up in the fracture clinic arranged Discharged home with advise regarding pain management, care of spica and signs & symptoms to look out for given
Evaluation
Time elapsed between registration and discharge was 90 minutes Adequate communication with Joey and his mother step by step explanation of the care plan was given Specialists were consulted as required and the most appropriate care/treatment provided Analgesia was offered several times and refused available in the community already established -both Joey and his mother seemed to be satisfied with the service they were receiving
Re-Evaluation
To cast or to splint? The application of a cast causes decreased mobility and increases the likelihood of osteoporosis. Many physicians limit casting in children with O.I. as much as possible and will often apply a splint and wrap the area with an elastic bandage instead (Osteogenesis Imperfecta Foundation, 2012)
Current Treatment and Hopes for the Future
No cure for O.I. Proper medical and orthopaedic management of the symptoms Sofield Osteomy – indicated for O.I. patients with repetitive fractures or progressive angular deformity in a weightbearing bone (Li et al, 2000) Ireland – study by Aravindan et al (2003) - Sheffield telescoping intramedullary rod system Studies in progress:
Bone and Vibration Treatment Study O.I. Nutrition Study Bisophosphonates
