femoral head is anterosup. to the true acetabulum
• Synovial biopsies
• Intra articular fusions
• THR
• Hemiarthroplasty
• Excision of tumors
• Pelvic osteotomies using upper part of approach
UMY
LANDMARKS:

of the iliac crest to the ASIS.
Curve down from ASIS vertically
for 8-10cms heaving towards
lateral side of patella.
UMY
INTERNERVOUS PLANE:
Superficial plane b/w Sartorius (innervated by
femoral N.) & TFL(innervated by Sup.glut.N)

UMY
UMY
Carefully cut through the gap b/t sartorius and TFL about 3” distal to
the ASIS.
Avoid cutting Lat. cut .N. of thigh, incise deep fascia.
UMY
Retract sartorius upwards & medially; TFL down & laterally

Detach and retract the R.F ,expose the capsule of hip jt.UMY
Adduct & externally rotate the leg to stretch the capsule.

UMY
UMY
DANGERS:
NERVES:
LFCN. of thigh- may be injured b/w sartorius & TFL.
Femoral N. – may be injured if plane is missed during deep dissection as
it lies anterior to hip , medial to RF, lateral to the femoralA.
VESSELS:
Ascending branch of Lat.Circumflex F.A.- May be injured in the plane
b/t TFL & Sartorius.
ENLARGING THE APPROACH:
PROXIMAL EXTENSION- For bone graft harvesting
DISTAL EXTENSION- For intraoperative fracture of distal femur
In superficial dissection - by detaching sartorius at the origin.

UMY
UMY
ANTEROLATERAL APPROACH:
( WATSON-JONES APPROACH)
• Most commonly used for THR
• Releases all abductor mechanism, hence hip can be adducted fully
hence acetabulum is fully exposed.

cutting the ant.part of GL.medius & the whole Gl.minimus off the G.T
INDICATIONS:
• THR
• ORIF of # NOF

Sup.GT N.)
UMY
UMY

distally to expose the vast,lateralis muscle.
UMY
Lift the ant. Flap & detach few fibers of GL.medius to develop a plane b/w TFL &
GL.medius.

UMY
UMY
Detach reflected head of Rect.F from Jt. Capsule to expose the ant. rim of
acetabulum
UMY
Place Homan retractor over ant lip of acetabulum beneath the RF & psoas as
the nervous bundle is anterior to the psoas.
Incise the capsule longitudinally.
UMY
• FEMORAL N-Not flexing the hip after dissecting
upto anterior rim of acetabulum
Placing retractors into substance of iliopsoas
Or overexuberant retraction can damage it..

acetabular retractors that penetrate iliopsoas
substance.
Anterior retractors (R) – 1-o` clock position
(L) – 11-o` clock position.
• PROFUNDA FEMORIS ARTERY

above GT.
• Prevented by stay suture in the GL. Med

• Prevented by placing retractor strictly on the bone.
VESSELS:

UMY
HARRIS APPROACH
• LATERAL APPROACH FOR EXTENSIVE EXPOSURE
OF THE HIP.
• Permits hip dislocation ant & post.
But requires GT osteotomy.
So risks are Trochanteric non-union,
Trochanteric bursitis,
Heterotopic ossification
UMY
SOME OTHER MODIFICATIONS
McFarland & Osborne lateral
approach
• Preserves the integrity of the
gluteus medius muscle.
• Combined mass of g.medius
& vastus lateralis with their
tendinous junction is elevated
& retracted anteriorly.
Hardinge lateral
Transgluteal approach
• Strong mobile tendon of
gluteus medius is incised
obliquely across GT leaving
posterior half still attached
to GT.
• GT Osteotomy is avoided.
UMY
GIBSON MODIFIED KL incision making it more
anterior but still angled.
• Iliotibial band is incised along with its fibres,
gluteus medius & minimus are divided at their
insertions leaving enough tendon attached so
that closure is easy & post-op rehabilitation is
rapid
Gibson’s Posterolateral approach
UMY
UMY
Gibson Approach Modified
By Marcy and Fletcher
• For insertion of a prosthesis in which the hip is
dislocated by internal rotation .

C
ADE- KOCHER LANGENBECK INCISION
BDE-GIBSON ORIGINAL SKIN INCISION
CDE- MODIFIED GIBSON APPROACH UMY
What are the modifications ???
• Making vertical skin incision.- More cosmetic in
obese female dec risk of postop “saddlebag” soft
tissue deformity.
• Limiting extent of hip joint capsultomy.

Post.div of obt.N. lies with in the obt,externus which it
supplies before it leaves the pelvis.
Runs down the thigh on adductor magnus under the

QUESTION?????
• Which of the following approaches for total hip
arthroplasty is reported to have the lowest
prosthetic dislocation rate?
• 1. Posterior approach with posterior soft tissue
repair
• 2. Anterolateral (Watson Jones)
• 3. Direct lateral (Hardinge)
• 4. Transtrochanteric
• 5. Posterior approach without posterior soft
tissue repair
UMY
Ans--LATERAL APPROACH
• The metanalysis by Masonis and Bourne
found a dislocation rate for 14 studies
involving 13000 total hips-
• 1.27% for the transtrochanteric approach,
3.23% for the posterior approach (3.95%
without posterior repair and 2.03% with
posterior repair),
• 2.18% for the anterolateral approach,
• 0.55% for the direct lateral approach.
