Inferior Hip Dislocation During Treatment of Developmental Dislocation of Hip. A Rare Complication from Hip Abduction Splint. A Case Report and Review of Literatures - Abstract
Background: DDH constitutes a group of conditions involving hip sublaxation and dislocation. It is mandatory for management of these cases to be followed by aftercare with Braces. Some complications may develop during follow-up in hip spica or hip brace. Introduction: DDH encompasses a spectrum of diseases that includes dysplasia (a shallow or underdeveloped acetabulum), subluxation, and dislocation. These conditions are commonly seen with arthrogryposis, myelomeningocele, and Larsen’s syndrome. Cases of developmental dislocation of the hip (DDH) still occur after walking age because of Late or missed diagnosis and failed conservative treatment. Lack of follow-up leads to a lot of Complications. Case Presentation: 4years old female child admitted to our hospital complaining of limbing and had neglected history of right DDH. She w managed by derotation femoral osteotomy and hip spica cast with smooth follow-up recovery. At 12 weeks an abduction hip brace was advised but follow-up last for few weeks. When returned back and during routine x-ray inferior dislocation was noticed. Patient planned for surgery and hip Spica cast. Follow-up passed smoothly for 12 months then the Spica cast replaced by Abduction hip brace. The reduction was confirmed by good x-ray. Discussion: Bracing is an important step in follow-up treatment program of DDH. Loss of reduction as a complication may occur during follow-up regimen. Inferior hip dislocation in the hip abduction brace is a rare complication and rarely mentioned in the literatures. Avoidance of this complication can be achieved by having good orthotics in the hospital and applying the brace under supervision of the orthopedic surgeon. Immediate x-ray to check for good position of the head, and closed monitoring of the patient to detect any changes in the hip position. Conclusion: Inferior hip subluxation in the hip brace rarely occurs as a complication during follow-up program of DDH treatment. Early recognition of this complication and reduction of the flexion angle led to a stable dislocation of the hip.
