Mr Rajesh, 40 years male
Childhood T. B. Hip
Totally disorganised joint
No socket to put Acetabulam
6 cm shortening

Patient still wanted mobile, stable, painless hip !!!!
Severely destroyed head and socket of hip joint
Chances of damage to nerve in such cases
are very high if we try to lengthen the leg

Massive Reconstruction of hip in a case of aggressive cancer of bone
• Mr Dharampal, 38/m.
• Moderate pain Lt- hip 1year
• Inability to sleep because of pain
• Investigations : CHONDROSARCOMA of
acetabulum
Radiograph showed destruction of socket of hip
Chondrosarcoma is a dangerous cancer of bonethat spreads rapidally if not treated in time
CT-SCAN
Measurement of cancer done to properly plan the surgery And put the prosthesis of appropriate size
We measured all possible dimensions of cancer
MRI was done to see any involvement of adjoining muscles
BONE SCAN done to rule out other area envolvement
BIOPSY
chondrosarcoma
We did
• Wide resection of tumor through abdomenand buttock
• Surgery last for 14-hours
• Oncosurgeon was also envolved with us
SURGICAL INCISION
Reconstruction of hip with Acetabular cage, Bone graft and Uncemented hip replacement
marginal biopsy - no activity
HERNIA MESH WAS USED TO HOLD GRAFT IN PLACE
At 6 weeks bone graft is well incorporated
At this stage he is able to sit. Able to walk non weight bearing
Message
• Although treating tumor in such places is difficult but not impossible
• Well planned surgery and extensive properative planning is needed to treat such cases
• Restoration of function of individual is the aim but only after complete removal of tumor
