We aimed to examine the outcomes of arthritic congenital dislocation of hip in adults after subtrochanteric shortening derotation osteotomy (SSDO) with cementless hip arthroplasty at a minimum follow-up period of five years. Bibliographic databases were searched and isolated studies were divided into three groups (1, 2, and 3) based on the femoral stem type (modular, monoblock, or mixed). We pooled 931 hips/737 patients from 20 studies. The mean difference in the Harris hip score (HHS) before and after the operation was 47.55 (95% confidence interval [CI] 43.16, 51.94). On subgroup analysis the mean differences of 46.59 (95% CI 41.67, 51.51), 48.24 (95% CI 41.37, 55.11), and 47.30 (95% CI 43.85, 50.75), respectively in HHS were noted in groups 1, 2, and 3. The incidence of uncontrolled proximal femur fractures was comparable at 7.9% and 4.2% in groups 1 and 2; however, it was 0% and 16.6% for controlled fractures. The incidences of nonunion, dislocation, nerve paralysis, heterotopic ossification and revision due to any cause were 0.3%, 6.5%, 1.7%, 2.1%, and 7.9% for group 1 and 1.9%, 4.3%, 1.6%, 5.6%, and 7.4% for group 2. Similar improvements in functional outcome for both monoblock and modular stems can be expected. An increased incidence of controlled proximal femur fractures was observed with use of modular stems. The nonunion at the SSDO site was sporadic.

Recurrent anterior shoulder dislocation (RASD) in cases of seizure disorders (SDs) total 50%–80% of all SD-associated shoulder instabilities. Based on the extent of bone loss, treatment options include bony and soft-tissue reconstructions, arthroplasty, and arthrodesis. The primary objective of this paper was to review the treatment options for RASD in SDs. Methods: Several bibliographic databases were searched for RASD treatment options in SD patients. The demographic outcome measures, the failure rate (defined as the relative risk of recurrence of dislocation postoperation), and the postoperative seizure recurrence rate were recorded. Results: We pooled 171 cases (187 shoulders) from 11 studies. Of these, one, five, two, two, and one reports studied Bankart’s operation with remplissage (27 cases/29 shoulders), the Latarjet procedure (106/118), bone block operation (21/23), arthroplasty (11/11), and arthrodesis (6/6), respectively, in treating SD-associated RASD. The relative risk of failure between SD and non-SD patients was 3.76 (1.3610.38) after the Latarjet operation. The failure rates were 17% and 13% for Bankart’s operation with remplissage and the Latarjet procedure in SD patients, respectively, but 0% each for bone block operation, arthroplasty, and arthrodesis. The total rate of seizure recurrence after operation was 33% of the pooled cases. Conclusions: SD recurrence in the postoperative period, the size of the bone block, and the muscular attachments to a small coracoid autograft are the determinants of failure among various reconstructive operations in SD-associated RASD. Level of evidence: III.
