Improved divergence angles with femoral interference screw placement through the tibial tunnel as measured by multiplanar reconstruction computed tomography.

Purpose: A modified technique for anterior cruciate ligament (ACL) reconstruction without graft injury by femoral interference screw insertion directly through the tibial tunnel is reported. This study evaluated femur bioabsorbable interference screw divergence and obliquity of the graft and tunnel positions as measured by multiplanar reconstruction computed tomography (MPR-CT) after endoscopic ACL reconstruction.

Methods: Twenty-five patients who underwent single-incision arthroscopically assisted ACL reconstruction using hamstring tendon autografts were enrolled in this prospective study.

Great saphenous vein thrombosis causing acute pulmonary embolism suggested by combined CT venography and pulmonary angiography.

Pulmonary embolism is a life-threatening condition, which is most commonly related to deep vein thrombosis. Varicose vein thrombosis, a very common disease, is seldom reported as being related to pulmonary embolism. We present combined computed tomography venography and pulmonary angiography findings suggesting that thrombosed varicosities of a great saphenous vein caused acute pulmonary embolism in a 30-year-old male.

Tubular acetabular intraosseous contrast tracking in MR arthrography of the hip: prevalence, clinical significance, and mechanisms of development.

Objective: The purpose of this study was to describe tubular intraosseous tracking of contrast medium in the acetabular fossa, to our knowledge a previously undocumented imaging finding in MR arthrography of the hip, and to discuss its prevalence, clinical significance, and possible mechanisms of development.

Conclusion: Tubular acetabular intraosseous contrast tracking is a common MR arthrographic finding that seems to have little clinical significance. Although the exact pathophysiologic mechanism is unknown, we presume repeated pumping of joint fluid through the nutrient foramina of the acetabular fossa may be one mechanism.

Complications of hip arthroscopy: analysis of seventy three cases.

Background: Hip arthroscopy is recognized as a highly effective means of treating joint disorders. Complications in hip arthroscopy, including neurovascular traction injury, compression injury to the perineum and scope trauma, have been reported. We report our experience with 73 hip arthroscopy procedures and complications at Chang Gung Memorial Hospital.

Evaluating hip labral tears using magnetic resonance arthrography: a prospective study comparing hip arthroscopy and magnetic resonance arthrography diagnosis.

Purpose: To evaluate the sensitivity and accuracy of magnetic resonance arthrography (MRA) with true sagittal scout image mapped radial reformation in localizing hip labral tears.

Type Of Study: Case series.

Methods: Thirty patients were examined with hip MRA because of suspected labral tears.
