Case summary
• A 25 years old male, met with RTA,
• Sustained hip fracture - dislocation
• Comminuted neck + trochanter
• Subtrochanteric fractures.
• Fractures of lower end radius, metatarsals, ligamentous injury at same side knee
• Contra-lateral comminuted fracture tibia fibula.
Radiology
• Fracture/dislocation of hip with fracture of head and neck
• Comminuted subtrochanteric fracture - Rt
• Comminuted fracture of Tibia/ febula Lt.
• CT scan of Rt hip was ordered.
Planning
• First nailing for Tibia on the other side.
• Open reduction of Hip
• Fixation of the head fragment with the remaining head.
• A bridge plate from trochanter to shaft bye-passing the comminuted pieces of subtrochateric region.
6/12/2011- Problems
• Split head fragment and how to fix it?
• How to reduce?
• Positioning of the pt. on table?
• Which approach?
• Traction table or not?
• Which implant?
6/12/2011- Problems
• Primary replacement with cemented Bipolar?,
• How to fix the two pieces of the head with out further damage to the vascularity?
• Intramedullary or extramedullary implant and their purchase in the neck fragment?
• How to avoid the rotation of neck fragment if a DCS/PFN or DHS is chosen?
14/12/2011Surgical notes
• Lateral position , posterior approach, blunt dissection
• Identification of the dislocated head fragment.
• There was a capsular rent in the inferior aspect through which the dislocated head was popping out.
• The capsular rent was not wide enough.
• We failed to manipulate the head fragment back in to acetabulum by direct pushing the head.
14/12/2011Surgical notes
• A gap was developed in the trochanteric area and trochanter was reflected upward(like we do in trochanteric osteotomy), through which the neck of the femur was caught by a patellar clamp and distraction was done. The head was now manipulated and deposited in the acetabulumand the reduction was checked by C-arm.
• A trochateric plate was chosen as a fixation device with out opening the subtroch fracture site.
14/12/2011Surgical notes
• I could not imaging the how to fix the two pieces of the head when the other was not visible. To expose means complete capsulotomy! I did not dare. So, I left it without fixation but in good alignment.
• The chance of AVN is much more than normal and I had to reconstruct the anatomy as near normal as possible.
• The case here presented with an idea of reporting a situation which is most unpleasant for any surgeon -who was forced to enter the theatre with out a clear pre-op planning due to bad comminution of the fractured bones.

Immediate Post op
31/1/2012Infection
• Unfortunately patient had deep wound infection which was explored and washed. The plate was holding well and I had no other choice hence was left in place.
• He was on antibiotics and now wound has nearly healed.
• He has difficulty in sitting upright.
• He was developing bedsores.
31/1/2012
• He was again taken to OT for hip examination. His c-arm pictures are attached here with.
• The lateral view showing marked anterior rotation/displacement of proximal fragment.
• I have to wait for at least 3 months for re-exploration + bone grafting.
Examination under C-arm
Examination under C-arm
Surgery .....
• In lateral position – Hip exposed.
• The external rotators were gentaly elevated from the posterior acetabular side and the head was reduced in the socket.
• Reduction was confirmed by C – arm.
• A long screw was tighten through a trochnateric plate into the fragment under vision through the capsular rent.
20/5/2012Infection + Bony Ankylosis
• Six months passed
• This patient now have bony ankylosis of hip with occasional dischage.
• Painless. Mobilized with walker.
• Planning to do hip excision once subtrochanteric fracture consolidates.
23/5/2012Problems & Choices
• For a stable painless hip,
• Debridement
• Control of infection antibiotic beads
• Excision of the Hip and/or Antibiotic spacer.
• At present I am concentrating of mobilisation. The infection (low grade) is probably in the hip joint that caused ankylosis.
• There is no loosening seen on x-rays at any screw tracts.
7/11/2012Plate removal
• Patient had persistent problem in ADL and specially sitting due to stiff hip.
• Discharge was persisting.
• Trochanteric plate was removed.
• Excision of hip was done.
• There was movement at proximal femur fracture.
• Temporary immobilization in Thomas’s splint.
• Mobilization continued with walker.

13/8/2013
• No infection.
• Mobility at proximal femur.
• Better mobilized due to movements at hip and proximal femur.
• Fracture exposed.
• Fragments mobilized
• Re-plating and bone grafting done.
• Reactivation of infection, which continued till the plate was removed on May 2014.

Finally
• Shortening of 2”
• Limited knee movements
• Walks without support with shoe raise
• No infection
• No pain
• No future planning for any hip replacement as there is no medullary canal in proximal femur.
