Varus Derotation Osteotomy
              Physiotherapy protocols following varus derotation osteotomy and pelvic osteotomy procedures.
            
                                                  Varus derotation osteotomy and soft tissue releases
      
          - VDRO will result in a leg-length discrepancy if done only on one side
 - Expect hamstring length to be functionally increased. Femoral shortening occurs with varus osteotomy, resulting in improved hamstring range of motion (ROM)
 - Despite adductor release, abduction ROM may not be significantly increased. Surgical correction during the VDRO takes away the abduction range
 
Goals: Pain management, equipment, early mobilization, discharge and transition to home
- Adjust seating as necessary to support the legs
 - Teach the family transfers – sliding board, manual or mechanical lift
 - Passive ROM/AAROM to joints not restricted in the cast
 - Ankle plantar flexor stretches, if required
 - Hip flexion should not be limited with VDRO only
 
Goals: Maintain joint range of motion (ROM), mobilization
- ROM – PROM/AAROM to joints not restricted in the cast
 - Consider alternate positions
 - Avoid windswept posturing during the healing process
 - Consider lying on the stomach; required if the psoas/iliopsoas release
 - Frequent position changes to prevent pressure areas
 - Isometric contraction of glutei, quadriceps and hamstrings, if able
 
Reminder: Progression of these activities will be confirmed in the child’s post-operative appointment
Goals: Hip and knee ROM, return to pre-op function
Positioning
- The child may experience increased spasms/discomfort when the cast is removed and greater movement is allowed. Using the hip abduction splint for this transition may be helpful; e.g. you may choose to use a splint for stability during transfers
 - Use a resting splint or pillow throughout the night for three months and during the day for napping and floor/sitting activities (e.g. watching television)
 - Out of brace for functional mobility during the day
 - Return to regular wheelchair seating with pommel
 
Range of motion (ROM)
- All hip ROM restrictions are removed – confirm with orthopedic team
 - PROM and AAROM of all LE joints; work towards full LE ROM in all planes; do not force range
 - Consider stretching the following:
- Adductors
- Hip in extension (i.e. supine) - with knee extension and knee flexion (frog leg position)
 - Hip in flexion - with knee extension and knee flexion
 - Ring or cross-leg sitting for play
 
 - Hip flexors
- Lying on stomach
 
 - Hamstrings
 
 - Adductors
 - Scar mobility as required
 
Returning to activity
- Begin pool therapy program for ROM, strengthening and initiating weight-bearing – confirm weight-bearing with the orthopedic team
 - Expect to progress to partial weight-bearing with a walker during this time, even if not used pre-operatively, to establish good postural habits and avoid early compensation – confirm weight-bearing with the orthopedic team
 
Goals: Return to full weight-bearing, return to full activity
Positioning
- You may discharge use of the night splint/pillow depending on radiological findings, tone and range of motion
 - Ensure hip abduction range of motion is maintained. Consider continued use of the splint/pillow for daily stretching
 
Activity progression
- Initiate weight-bearing if it is not already done. Begin to ambulate with a walker even if not used pre-operatively, to establish good postural habits and avoid early compensation – confirm weight-bearing with the orthopedic team
 - Evaluate the need for a shoe raise, due to shortening that occurs with femoral osteotomy (if unilateral)
 - Start endurance exercises with low load and high repetition. Progress to strengthening exercises with mild resistance
 - Strength training – hip abductors and extensors, and knee flexors and extensors
 - Gait training
 - Balance training
