the natural history of an untreated case of a developmental dysplasia (dislocation) of the hip (ddh) associated with multiple congenital abnormalities is reported in a 55-years-old man. the patient’s complaints and the varieties of the typical manifestations emerged in other parts of the body throughout the life are reviewed and discussed as comorbidities of a dysplastic condition. two-stage bi...

Background. The choice of pelvic reconstruction technique in children with developmental dysplasia the hip (DDH) has been subject discussion for many years and is often determined by personal preferences a surgeon rather than X-ray anatomical state acetabulum. variants its anatomy structure have still not reflected available scientific literature.
 Aim study to identify most typical acetab...

BACKGROUND The gluteus medius muscle is essential for gait and hip stability. Changes that occur in the gluteus medius muscles in patients with developmental dysplasia of the hip (DDH) are not well understood. A better understanding of DDH related changes will have positive repercussions toward hip soft tissue reconstruction. METHODS 19 adult patients with unilateral DDH scheduled for total h...

BACKGROUNDS Non-traumatic hip dislocation in children is most often observed in the course of developmental dysplasia of the hip (DDH) and infantile cerebral palsy. The risk of pain sensations from dislocated hip joint differentiates the discussed groups of patients. Will every painless hip joint in children with cerebral palsy painful in the future? METHODS Material included 34 samples of jo...

Achondroplasia (ACH) is the most common form of hereditary dwarfism and presents with multiple musculoskeletal anomalies but is not normally associated with premature hip arthritis. Developmental dysplasia of the hip (DDH) is a spectrum of disease resulting in shallow acetabular depth and a propensity for chronic femoral subluxation or dislocation; it is among the most common causes of prematur...

INTRODUCTION: Developmental dysplasia/dislocation of the hip (DDH) is the most common post-natal skeletal abnormality, and occurs when the joint between the femoral head and the acetabulum is unstable or malformed, or when the femoral head is partially or completely dislocated from the acetabular cup [1]. It is widely acknowledged that conditions which cause or result in reduced movement in ute...

Patients with neglected developmental dysplasia (DDH) face with early osteoarthritis of the hip, limb length inequality and marked disability while total hip reconstruction is the only available choice.DDH has severe morphologic consequences, with distorted bony anatomy and soft tissue contractures around the hip. It is critical to evaluate patients thoroughly before surgery.Anatomic reconstruc...

PURPOSE To evaluate the use of the popliteal angle as an indicator for successful closed reduction of developmental dysplasia of the hip (DDH) in children with delayed presentation. METHODS 29 patients aged 6 to 18 months underwent successful closed reduction for unilateral DDH under general anaesthesia. Using a graduated goniometer, the popliteal angle was measured with the hip abducted with...

BACKGROUND Different extents and locations of acetabular cartilage defect have been supposed to be a major cause of undesirable outcomes of periacetabular osteotomy (PAO) in patients with developmental dysplasia of the hip (DDH). This study aimed to verify whether different locations of cartilage deficiency affect the biomechanical environment in a three-dimensional model utilizing finite eleme...
