Investigation of the Femoral Shortening Osteotomy in the Developmental Dislocation of the Hip (FSODDH)

Investigation of the Value of Femoral Shortening Osteotomy During Open Treatment of Developmental Dislocation of the Hip in Waliking Age Group

• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 200 (estimated)
• Sponsor: He Jin Peng · Academic / Other
• Sex: All
• Age: 18 Months – 24 Months
• Healthy volunteers: Not accepted

Summary

Although older children and high dislocations may be more likely to require a femoral shortening osteotomy, the ultimate decision about whether or not to shorten a given femur should depend on the ease of femoral head reduction in that specific patient. Adding a femoral shortening procedure increases operating time and blood loss, adds a second incision, and necessitates future hardware removal. In addition, an unnecessary femoral shortening osteotomy could overly decrease the soft tissue tension around the joint, putting the hip at risk for redislocation. This study was designed to explore an algorithm based on strict age and radiographic criteria that identify those without the need of femoral osteotomy.

Detailed description

Developmental dislocation of the hip (DDH) is a common disease in children, and its incidence in China is about 9 ‰.There are many different methods in the treatment of DDH. Although older children and high dislocations may be more likely to require a femoral shortening osteotomy, the ultimate decision about whether or not to shorten a given femur should depend on the ease of femoral head reduction in that specific patient. Adding a femoral shortening procedure increases operating time and blood loss, adds a second incision, and necessitates future hardware removal. In addition, an unnecessary femoral shortening osteotomy could overly decrease the soft tissue tension around the joint, putting the hip at risk for redislocation. This study was designed to explore an algorithm based on strict age and radiographic criteria that identify those without the need of femoral osteotomy. From the investigators'clinical experiences and the published papers, younger patients (\<24 month of age) and low dislocations (Tonnis level I or II) were more likely to avoid a femoral shortening osteotomy.

Conditions
