Effects of different pelvic osteotomies on acetabular morphology in developmental dysplasia of hip in children

Table 1 Summation of previous studies with their case number and conclusions

Ref.	Pelvic osteotomies	Number of cases/hip	Conclusion
Sawamura et al[52]	Salter osteotomy	42/50	Showed favorable outcomes with satisfactory at skeletal maturity
Scott et al[53]		58/78	Improve acetabular morphology, reduced the incidence of advanced osteoarthritis and the probability of THA
Tan et al[55]	PAO	?/225	Lead to good deformity correction for both acetabular retroversion and hip dysplasia
Ali et al[56]		314/?	All acetabular parameters were observed to be improved
Dornacher et al[63]	TPO	176/206	Acetabular parameters recovered well, intraoperative fluoroscopy increased the accuracy of the operation
Lyu et al[64]		43/48	Improve parameters of the acetabulum, makes the complex operation safer and more effective
Bhatti et al[67]	PPO	60/82	The hips with Pemberton's acetabuloplasty exhibited better acetabular coverage and progressive development of hips as compared to Salter's osteotomy
Czubak et al[71]	Dega osteotomy	45/52	It is a safe and adequate operation to restore the acetabulum to normal or close to normal
Badrinath et al[76]	San Diego osteotomy	?/45	It is a safe and effective alternative to treat acetabular dysplasia in patients with typical DDH and can solve specific acetabular defects
Ito et al[82]	Chiari pelvic osteotomy	31/32	Improve acetabular index, relieve pain and reduce hip replacement rate
Dammerer et al[81]		12/12	Improve the acetabular coverage of the hip joint and suitable for some specific older children
Yoo et al[84]	Shelf pelvic osteotomy	14/14	Improve the depth and coverage of acetabulum and can stimulate the growth of acetabulum
Benad et al[85]		56/61	Relieve pain symptoms, improve joint function and delay THA in patients

PAO: Periacetabular osteotomy; TPO: Triple pelvic osteotomy; PPO: Pemberton pelvic osteotomy; THA: Total hip arthroplasty; DDH: Developmental dysplasia of the hip.
