Southern/Moore approach aka, describe 3 |
Kocher-Langenbeck approach, posterior appr
No internervous plane Incision=>1 longitudinal incision centered over greater trochanter, 2 start just below iliac crest, lateral to PSIS(-mini-incision approach shows no longterm benefits to hip function) 3 extend to 10 cm below tip of greater trochanter |
|
posterior approach Provides exposure to (4) 3 criteria
|
1 post wall fx, 2 post column fx & 3 post wall and post column fx;4 simple transverse fx (patient prone) flex kne
fx must be less than 15 days old fx line located at or below acetabular roof no major anterior displacement |

Stoppa Approach to Acetabulum
|
excellent access to ant column of aacetebulaum and quadrateral plate. beter visualisation than illiinguanal approach
|
|
55yoM s/p mva w/ fx pattern in Fig A. Which of the following approaches would provide the best exposure for ORIF? 1 Mod Stoppa A; 2 Extendd Iliofemoral; 3 Kocher-Langenbeck; 4 Med window of the ilioinguinal; 5 Simultaneous ant & pos exposr
|
Figure A is acetabular fracture pattern with medial displacement of the quadrilateral plate. stoppa allows the middle window of the ilioinguinal approach to be avoided, resulting in minimal dissection inguinal canal, femoral n & external iliac vessels.Ans 1 |

difference bt/Woven bone vs Lamellar bone
|
mmature or pathologic bone that is woven and random and is not stress oriented |
