All patients were available for follow-up. The mean age at surgery is 10.3 years (range 4 to 15) and the mean follow-up period is 16 mo (range 9-28).

¹One patient died approximately 3 mo post-surgery following a severe respiratory tract infection (pneumonia ab ingestis). GMFCS: Gross Motor Function Classification System; VDRSO: Varus, derotational, shortening femoral osteotomy; M: Male; F: Female.

Table 2 Post-operative rate of complications (n = 21)

Complication	n (%)
Avascular necrosis (femoral head)	0 (0.0)
Bone graft dislodgement	0 (0.0)
Hip dislocation	0 (0.0)
Premature triradiate cartilage closure	0 (0.0)
Pathological fracture	2 (9.5)1
Post-operative pain	1 (4.7)
Pain at last follow-up	0 (0.0)
Post-operative infection	0 (0.0)
Death	1 (4.7)2

¹One femur fracture occurred at the distal metaphysis and was not directly related to the surgical procedure (osteoporosis). The other fracture occurred 18 mo after surgery at the distal end of the metal hardware (trauma);

²One Gross Motor Function Classification System V patient died approximately 3 mo post-surgery due to a severe respiratory tract infection.
