Periprosthetic fracture
54 yr old hypophosphatemia rickets with spondyloepiphyseal
dysplasia. Periprosthetic fracture following a fall in a bowed femur . H/o multiple previous fractures Leading to sheperds crook deformity.


An eto foe quick explantation an correction of proximal deformity and distal locking was planned. The distal deformity correction although was kept in mind but not corrected as it would possibly cause LLD. We got him walking at 6 weeks to get on growth due to the capacious canal and hypophataemia. Wonder whether a distal stress riser will cause an issue in his life time. in his life time.

63 yr old patetient with the above fracture 5 years post both column acetabulum fracture sequlae with implant removal 5 months post op due to Klebsiella infection. now asymptomatic(infection) presented with a communited sub trochanteric fracture
intraop frozen section, cultures and options of 2 stage and single stage were discussed with decision to depend on frozen section taken to avoid 2 surgeries. negative frozen section and hence THR through the trochanteric fracture (Like a flip) was done with wagner stem
43 years old post head injury and heterotopic ossification due to head injury.
Had infection post attempted HO excision on Lt hip 4 weeks ago. The surgical perspective improves with 3 D printing by infillcube at Kakanad, Kochi. The head and acetabulum appeared partly destroyed suggesting infection and hence a 2 stage THR with dual mobilty or constrained hip was planned
post op pics with cement spacer and stimulan with vacomycin and polymyxin and postop of vac dressing to eliminate the dead space.

26 years post conservatively treated acetabular fracture with pain and Limp
- Used Patients femoral head with a reverse L cut to fill the posterior wall defect and a uncemented THR was done in 2002. the xrays below are at 18 years with no symptoms but superior linear wer is an issue and has to be followed up closely. The AML stem metal head 22 mm head with standard poly was the only available solution in 2002 in india. one had to push hard on JNJ to bring in larger ceramic bearings those days

CT and Xray taken 19 years later with no symptoms. shows predictable superior wear with no periprosthetic lysis. the older standard polyethylene and 22.5 modular head in a very active gentleman

Painful flail lt knee post PPRP in 52 year old
52 yr old lad PPRP had THR rt side due to pain in a dysplastic hip 8 yrs back. followed by periprosthetic fracture 2 yeasr post op. Nov presents with pain lt knee at rest worse on wlking. cannot tolerate pain any more in the lt flail knee. Attempted bracing to prevent the 30 degree hyperextension with no relief. Hence an RHK was done to eliminate pain and improve her gait secondarily. In a flail limb do we do a rotaing hinge or simple hinge. the literature is a bit grey. we need a 5 degree recurvatum with a further stop ideally. We improved her gait and relieved pain for now with a link RHK with recurvatum stop
HIP REPALCEMENTIN FRESH ANTERIOR COLUMN FRACTURE
