<br> - protrusio and hip flexion contractures are common; <br> - heterotopic ossification may follow THR; <br> - total hip replacement: <br> - hetertopic ossification; <br> - occurs in 20-40 % of hip replacements and is more common w/ trochanteric osteotomy; <br> - to avoid heterotopic ossification consider insertion of a cemented acetabular component followed by 750 rads around the component; <br>Wheeless' Textbook of Orthopaedics 2002-02-04 22:29:17 GMT http://www.orthopaedicweblinks.com/cgi-bin/owl/jump.cgi?ID=4436 C.R.Wheeless http://www.orthopaedicweblinks.com/Detailed/4402.html - Smith Petersen improved & revived the anterior iliofemoral approach; <br> - entire ilium and hip joint can be reached thru iliac part of incision; <br> - with this approach there is a need for extensive detachment of tendinous insertions & retraction of muscle, with potential damage to femoral artery and nerve and traction on lateral femoral cutaneous nerve;

<br> - surgical fusions are performed for young adults with advanced arthritis; <br>- indications: <br> - desire to return to near-normal physical activity with manual labor; <br> - 20 yrs years after surgery, 80% of pts w/ hip arthrodesis performed at relatively young age were working & satisfied w/ their results;

<br> - palpate the femoral pulse just as it exits the inguinal ligament; <br> - entry point is one inch lateral to the artery (at the inguinal ligament) and one inch below the inguinal ligament; <br> - going lateral 1 inch will also make entry site approx 1 in below ligament;

- formed posteriorly by large branch of MFCA - formed anteriorly by smaller branches of LFCA; - superior & inferior gluteal artery have minor contributions; - ascending cervical branches - these give rise to retinacular arteries; - gives rise to subsynovial intra articular ring - artery of ligamentum teres; - derived from obturator or MFCA; - inadequate to supply femoral head with displaced fractures; - forms the medial epiphyseal vessels; - only small & variable amount of the femoral head is nourished by artery of ligamentum teres; - epiphyseal blood supply: - arises primarily from lateral epiphyseal vessels that enter head posterosuperiorly; - vessels from medial epiphyseal artery entering thru ligamentum teres; - epiphyseal arterial branches: - arise as arteries of subsynovial intraarticular ring; - two groups of epiphyseal arteries: lateral & inferior vessels; - metaphyseal blood supply: - arises from extracapsular arterial ring; - arise from branches of ascending cervical arteries, & subsynovial intra articular ring; 2007-07-12 22:29:17 GMT http://www.orthopaedicweblinks.com/cgi-bin/owl/jump.cgi?ID=12051 Wheeless
