We report skeletal features that are consistent with hip dysplasia, as it is described in domestic dogs (Canis lupus familiaris) in a museum specimen of a red fox (Vulpes vulpes). Morphological identifiers included shallow acetabulae, femoral head flattening and subluxation, caudal curvilinear osteophyte, circumferential femoral head osteophyte, osteophytes of the acetabular margin, and femoral...

Background: Developmental dysplasia of the hip (DDH) is one of the most important and challenging conditions inthe field of pediatric orthopedics; if not diagnosed and treated in time, it would lead to remarkable morbidity. Methodsof treatment based on the patient’s age can vary. The aim of this study is to compare the outcomes of Salter osteotomysurgery in two groups of patients under and over...

Untreated acetabular dysplasia following treatment for developmental dysplasia of the hip (DDH) leads to early degenerative joint disease. Clinicians must accurately and reliably recognise dysplasia in order to intervene appropriately with secondary acetabular or femoral procedures. This study sought early predictors of residual dysplasia in order to establish empirically-based indications for ...

Osteoarthritis secondary to developmental dysplasia of the hip is a surgical challenge because of the modified anatomy of the acetabulum which is deficient in its shape with poor bone quality, torsional deformities of the femur and the altered morphology of femoral head. Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adduct...

The aims of this study were to determine the prevalence and heritability of elbow dysplasia in the Estrela mountain dog breed, to investigate genetic trends over the last 20 years (1990–2009) and to evaluate the association of individual records with breeding values. The elbows of 351 Estrela mountain dogs were examined using the flexed mediolateral radiographic view and evaluated using the Int...

BACKGROUND Uncorrected developmental dysplasia of the hip (DDH) is associated with long-term morbidity such as gait abnormalities, chronic pain and degenerative arthritis. OBJECTIVES To determine the effect of different screening programmes for DDH on the incidence of late presentation of congenital hip dislocation. SEARCH METHODS Searches were performed in CENTRAL (The Cochrane Library), M...

Dancers frequently present with hip pain. The etiology of this pathology has not been clearly identified from an anatomical perspective. Structural variations including hip dysplasia and dynamic variables from the foot to the pelvis will be discussed. Understanding the etiology as a structural entity, neuromuscular entity or a combination of the two, allows for a successful rehabilitative proce...

BACKGROUND Each year, thousands of children worldwide suffer obstetric brachial plexus nerve injuries resulting not only in primary nerve injury, but also in development of secondary muscle and bone deformities of the shoulder. The triangle tilt surgery has been developed and shown to effectively address these deformities. The triangle tilt procedure was initially designed by the lead author (R...

BACKGROUND The arthroscopic management of hip dysplasia has been controversial and has historically demonstrated mixed results. Studies on patients with borderline dysplasia, emphasizing the importance of the labrum and capsule as secondary stabilizers, have shown improvement in patient-reported outcomes (PROs). Purpose/Hypothesis: The purpose was to assess whether the results of hip arthroscop...

Developmental disorder of the hip (DDH) is the most frequent disease of this joint. It is manifested by dysplasia, subluxation or luxation in childhood period and arthrosis in adults. Early degenerative changes of the hip occur at the location of disordered anatomy and biomechanics already in youth, while in the childhood age they are mostly asymptomatic (Ando & Gotoh, 1990). DDH mostly occurs ...
