Background: The study aimed to evaluate the clinical and radiological outcomes of Spitzy shelf acetabuloplasty in Legg–Calvé-Perthes disease (LCPD) excluding cases with hinge abduction.
Methods: This prospective case series study was conducted in the period from January 2018 to May 2020 at Cairo University Children’s Hospital (Abou El Reesh). A total of 20 cases were done. 16 were males and four were females. The mean age at onset of disease was 8.5 years (range: 8 years to 10 years). Pre-operatively, four patients were on the initial stage and 16 patients were on the fragmentation stage (six cases classified as lateral pillar group B and ten cases classified as group B/C). Patients were followed up for a mean of 18.3 months (range: 12 to 26 months). Clinical assessment was done using modified Sundt criteria. Radiological parameters were followed up. Stulberg classification was done for cases that reached the healed stage on follow up.
Results: Clinically, 17 cases were good and three cases were fair according to modified Sundt criteria. Radiologically, all the parameters improved significantly. Nine cases reached the healed stage on follow up. Three cases were classified as Stulberg II, five cases as Stulberg III and one case as Stulberg IV.
Conclusion: We recommend Spitzy shelf acetabuloplasty for the management of early stages of LCPD in patients with onset of the disease over eight years. This protocol of management yields a favorable clinical and radiological results with 88.9% of cases achieving Stulberg III or less outcome.
