– Discussion: – this extends over several months and sometimes much longer; – clinical signs persist, or worsen, & radiographs show changes in trabecular pattern of femoral head; – sclerosis may be diffuse, in localized areas, or in a linear arc which is concave superiorly
– See: Radiographic Findings – stable intertroch frx is one that when reduced has cortical contact w/o gap medially and posteriorly; – this contact will prevent frx displacement into varus or retro-version when forces are applied to proximal femur; – medial cortices are not comminuted & there is no displaced frx of lesser trochanter
– See: – PreOperative Planning: – preoperative leg length: – acetabulum: – evaluation of cup position: – acetablar component loosening – use a wax pen to mark the tear drop and the superior aspect of the acetabulum, and overlie … Read more
– See: Spondyloepiphyseal Dysplasia Congenita: – Discussion: – generalized skeletal dysplasia affecting primarily the spine & epiphyses of the larger, more proximally located joints; – many patients go unrecognized until the adolescent years when hip pain or scoliosis develops; – typically, patients develop hip pain and stiffness in the first or second decade and are … Read more
Discussion conditions include: AS Reiter’s Syndrome Psoriatic Arthritis Inflammatory Bowel Disease typically involves the axial skeleton; affected areas heal w/ fibroblastic proliferation followed by new bone formation; pathogenesis of these disorders is unknown except for Reiter’s syndrome, which is generally believed to result from aberrant host response to a pathogenic microorganism; Labs RF is negative; HLA-B27 phenotype: … Read more
– See: Spondyloepiphyseal Dysplasia Tarda: – Discussion: – a type of short trunk disproportionate dwarfism, in which there is involvement of the vertebra and epiphyseal centers; – can be transmitted as autosomal dominant trait, although most cases arise as random mutations; – symptoms include delayed developmental milestones, diminished endurance, and … Read more
– Discussion: – permits the guided insertion of a cannulated blade thru the nail and into the femoral head,at one of three angles to accommodate anatomic or fracture variations; – angle options: – key onto proximal nail end, adapting the nail slot to accept the spiral blade … Read more
– Discussion: – arises from thickening, contracture, and coalescence of the spiral band, Grayson’s liagment, and the lateral digital sheet; – it extends disatlly past the natatory ligament, first lying along lateral margin of the digit, but then courses toward the midline to insert into the central cord at the level of the … Read more
– See: Pseudoachondroplasia – Cervical Spine: – stenosis of foramen magnum: – all patients with achrondroplasty will demonstrate some radiographic stenosis of foramen magnum, and many can be shown to demonstrate either some at least some clinical symptoms or … Read more
– See: Cervical Spine in Ankylosing Spondylitis – Clinical Findings: – loss of lumbar lordosis; – back motion is limited; – note that ability to lean forward has more to do with hip flexion than lumbar spine flexion; – w/ forward … Read more
