reported a case of osteoblastoma occurring in the pelvis; the tumor involved the superior pubic ramus
, the superior part of the ischium, and the inferior part of the acetabulum.
However, due to new fractures on pubic ramus
, full weight bearing was delayed for approximately 6 months.
In this study, the case of a patient, who has been receiving bisphosphonate treatment for 10 years and developed multiple fractures (left femoral diaphysis, bilateral pubic ramus and sacrum), was presented and the literature was reviewed.
Positron emission tomography (PET) scans revealed a minimal increase in metabolic activity which is thought to belong to an old stress fracture in the cortex of the left femur diaphysis 1/3 middle section, and an increase of metabolic activity involvement in left side of sacrum and left superior pubic ramus fracture line.
Fatigue fracture of the inferior pubic ramus following total hip replacement for congenital hip dislocation.
Pubic ramus insufficiency fractures following total hip arthroplasty: a report of six cases.
When you feel the junction of the inferior pubic ramus with the body of the pubic bone--one of the two most important landmarks--you then can slide your finger along the obturator internus fascia right down to the ischial spine.
A first incision (no more than 5 mm) is made at the level of the urethra, about 1 cm lateral to the inferior pubic ramus, which you can palpate through the skin of the thigh.
The anteroposterior radiograph of the pelvis shows a lytic, expansile lesion of the right acetabulum that extends into the ilium and superior pubic ramus
with cortical breakthrough of the iliopubic line.
The obturator canal is a defect in the tendinous insertion of the obturator internus muscle onto the posterior aspect of the superior pubic ramus
, which is a passage way for the obturator neurovascular bundle (Fig.
