Insights
Developmental dysplasia of the hip (DDH) affects 3.75% of late-presenting Jordanian males. Cesarean delivery increases dislocation risk, while normal delivery is linked to acetabular dysplasia.
Area of Science:
- Orthopedics
- Pediatric Orthopedics
- Radiology
Background:
- Developmental dysplasia of the hip (DDH) is a common pediatric orthopedic condition.
- Late presentation of DDH in male patients requires understanding of specific risk factors and patterns.
Purpose of the Study:
- To describe the pattern of late-presenting developmental dysplasia of the hip (DDH) in Jordanian male patients.
- To identify risk factors and associated findings in this population.
Main Methods:
- Retrospective study of 1145 male patients with suspected DDH.
- Data collected from medical records and radiographic measurements between March 2011 and October 2014.
- Analysis of risk factors, presentation patterns, and associated conditions.
Main Results:
- 43 patients (3.75%) were diagnosed with late-presenting DDH, involving 70 hips.
- First-born status increased DDH risk by 41.9%.
- Cesarean delivery was linked to hip dislocation (p=0.004), while normal delivery was associated with acetabular dysplasia (p=0.004). Bilateral DDH was more common (60.5%). Limited abduction was a constant finding in dislocated hips.
Conclusions:
- Cesarean delivery is a significant risk factor for hip dislocation in DDH.
- Normal delivery is associated with acetabular dysplasia.
- Bilateral DDH is more prevalent than unilateral DDH in this cohort.
Objectives:
To describe the pattern of developmental dysplasia of the hip (DDH) in late presenting Jordanian male patients and identify the risk factors and associated findings.
Methods:
This is a retrospective study of 1145 male patients who attended the Pediatric Orthopedic Clinic for a DDH check up. This study was carried out in the Orthopedic Section, Special Surgery Department, Faculty of Medicine, The University of Jordan, Amman, Jordan between March 2011 and October 2014. Data was collected from medical records, and x-ray measurements were evaluated.
Results:
Of the 1145 male patients, 43 (3.75%) with 70 involved hips were diagnosed with late- presenting DDH. Being a first-born baby resulted in 41.9% increased risk for DDH. Cesarian delivery was significantly associated with an increased risk of hip dislocation (p=0.004) while normal delivery was significantly associated with acetabular dysplasia (p=0.004). No predictable risk factors were found in 44.2% patients with DDH. Bilateral cases were more common than unilateral cases: (26 [60.5%] versus 17 [39.5%]). Limited abduction was a constant finding in all dislocated hips (p less than 0.001). Associated conditions, such as club foot and congenital muscular torticollis were not observed.
Conclusion:
Cesarian section is a significant risk for dislocated hips while normal delivery is significantly associated with acetabular dysplasia. Bilateral DDH is more common than the unilateral. Club foot and torticollis were not observed in this series.

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
