- 25. • Intrinsic Hip ER: (6 muscles) • Piriformis, • Obturator Internus, • Obturator Externus, • Gemelus Superior, • Gemelus Inferior, • Quadratus Femoris • Piriformis Syndrome: • The sciatic nerve passes deep to the piriformis in most cases (approximately 85% of people)but can in fact pierce the piriformis itself, predisposing to piriformis syndrome and subsequent sciatica. UMY
- 26. Tensor Fascia Lata Muscle- "stretcher of the wide band" • Origin- Ant part of outer lip of iliac crest. • Insertion-Between the two layers of the iliotibial band of the fascia lata. • Nerve-Superior gluteal nerve (L4, L5, S1) • TFL muscle is a tensor of the fascia lata; continuing its action- Thigh - flexion, medial rotation,abduction. Trun k stabilization. UMY

ANTERIOR ILIOFEMORAL APPROACH: (SMITH PETERSON APPROACH) Gives safe access to hip & ilLium INDICATIONS: • Open reduction of congenital dislocations of hip when dislocated 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
- 32. LANDMARKS: ASIS, iliac crest. INCISION: Long incision over anterior half of the iliac crest to the ASIS. Curve down from ASIS vertically for 8-10cms heaving towards lateral side of patella. UMY
- 33. INTERNERVOUS PLANE: Superficial plane b/w Sartorius (innervated by femoral N.) & TFL(innervated by Sup.glut.N) Deep plane lies b/w RF (by femoral N.) & G.medius ( by Sup.glut.N.) UMY
- 34. UMY

- 36. Retract sartorius upwards & medially; TFL down & laterally Detach the TFL at iliac origin. Ligate the ascending branch of Lat.circumflex Fem A. in this plane.UMY
- 37. Separating sartorius & TFL exposes 2 muscles the GL. Medius & Rectus femoris. Pass into the plane b/w Rect,F & GL.medius which is lateral to the Femoral.A. Detach and retract the R.F ,expose the capsule of hip jt.UMY
- 38. Adduct & externally rotate the leg to stretch the capsule. Incise the capsule as required ( T/longitudanal)& dislocate the hip by ext.rotation. UMY

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. In deep dissection- Stay in plane b/w vastus lateralis & rectus femoris. UMY
- 42. • Reattachment of fascia lata to iliac crest difficult • Osteotomy of overhang of iliac crest is performed b/w Ext. Oblique medially & fascia lata to as far as origin of g.maximus. • TFL, G.medius & G.minimus dissected subperiosteally to expose hip joint capsule. • Closure – Iliac osteotomy fragment reattached with non-absorbable sutures through holes drilled. SCHAUBEL MODIFICATION OF SP ANTERIOR APPROACH UMY
- 43. • IND-For irreducible congenital dislocation of the hip in a young child. • TRANSVERSE ‘BIKINI’ INCISION – From anterior inferior and medial to the ASIS and coursing obliquely superiorly and posteriorly to the middle of the iliac crest. • REFLECTING ABDUCTOR → SARTORIUS & TFL→ REFLECTED HEAD OF RECTUS FEMORIS→ INCISION OF CAPSULE FROM RECTUS ANTERIORLY TO POSTEROSUPERIOUR MARGIN OF JOINT→ OPEN REDUCTION OF DDH SOMMERVILLE ANTERIOR APPROACH UMY
- 44. UMY
- 45. 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. • Abducor mechanism released either by trochanteric osteotomy / by cutting the ant.part of GL.medius & the whole Gl.minimus off the G.T INDICATIONS: • THR • ORIF of # NOF • Hemiarthroplasty • Synovial biopsy • Biopsy Femoral N.

- 57. Detach reflected head of Rect.F from Jt. Capsule to expose the ant. rim of acetabulum UMY
- 58. 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
- 59. • 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.. • VESSELS – FEMORAL ARTERY & VEIN – damaged by acetabular retractors that penetrate iliopsoas substance. Anterior retractors (R) – 1-o` clock position (L) – 11-o` clock position. • PROFUNDA FEMORIS ARTERY • FEMORAL SHAFT# - while hip dislocation esp if inadequate capsular release DANGERS UMY

- 71. 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
- 72. 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
- 73. 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
- 74. UMY
- 75. Gibson Approach Modified By Marcy and Fletcher • For insertion of a prosthesis in which the hip is dislocated by internal rotation . • Anterior part of the joint capsule is preserved to keep the hip from dislocating anteriorly after surgery. UMY

- 78. C ADE- KOCHER LANGENBECK INCISION BDE-GIBSON ORIGINAL SKIN INCISION CDE- MODIFIED GIBSON APPROACH UMY
- 79. 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. • Rather G Max splitting, interval between G max & TFL is developed.So, vascular supply of ant portion of G max is not at risk. • Better anterosuperior visualization & access. UMY
- 80. POSTERIOR APPROACH: (MOORES APPROACH- SOUTHERN EXPOSURE) • Most commonly used approach & practical • Easy ,safe, quick INDICATIONS: Hemiarthroplasty THR including revision ORIF of post. Acetabular # Dependent drainage in hip sepsis Removal loose bodies Pedicle bone grafting Open reduction of posterior dislocation UMY

- 95. UMY
- 96. DANGERS: NERVES: Ant,div of obt.N- which lies at the top of the obt.externus running b/w add.longus & brevis. 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 brevis,it also supplies adductor portion of adductor magnus. These nerves are transected if approach is meant for adductor spasm or else protect them. VESSELS: Medial femoral circum flex A.-may be injured at distal part of psoas. UMY
