Risk factors for dislocation after revision total hip arthroplasty with a dual-mobility cup. Matched case-control study (16 cases vs. 48 controls).
Reports of high dislocation rates after revision total hip arthroplasty (THA) have encouraged the widespread use of dual-mobility cups. Dislocation has been less common but not fully abolished with dual-mobility cups, and its causes have remained unidentified. The objectives of this retrospective matched case-control study were: 1) to identify risk factors for dislocation, 2) and to assess dislocation outcomes. ⋯ III, matched case-control study.

Selective neurotomy of the sciatic nerve branches to the hamstring muscles: An anatomical study.
Hamstring spasticity can bring about a flexion deformity of the knee, liable to cause disability. Surgical treatment by selective neurotomies of the sciatic nerve branches leading to the hamstring muscles may then be indicated. Few studies have investigated the precise origin of these branches on the sciatic nerve, describing the innervation pattern of the hamstring muscles. Further anatomical data are needed to enhance surgical techniques in neurotomies of the sciatic nerve branches, to define the best incision and surgical approach and what section and length of the SN need to be exposed. Therefore, we performed an anatomical study to: (1) define a surgical approach to perform selective neurotomies of the sciatic nerve branches for hamstring spasticity?(2) whether the anatomical variants of the hamstring innervation have been identified? ⋯ IV: prospective study without control.

Randomized Controlled Trial Comparative StudyComparison of oral vs. combined topical/intravenous/oral tranexamic acid in the prevention of blood loss in total knee arthroplasty: A randomised clinical trial.
Tranexamic acid (TXA) has long been used to reduce blood loss associated with total knee arthroplasty (TKA). Debate remains over the best administration route with limited data comparing regimes including, to date, no studies investigating the equivalence of oral TXA and a combined topical/intravenous (IV) regime. Therefore, the aim of this study was to compare the efficacy and safety of oral TXA to combined topical/IV/oral TXA. ⋯ II, Randomised controlled trial.

Observational StudyEvaluation of an oral analgesia protocol for upper-limb fracture reduction in the paediatric emergency department: Prospective study of 101 patients.
Upper limb injuries are common in children. When required, closed fracture reduction can be performed in the emergency department without general anaesthesia but causes pain. The primary objective of this study was to assess an oral analgesia protocol for fracture reduction without general anaesthesia. The secondary objectives were to look for associations linking pain intensity to age, sex, and waiting time and to determine the frequency of secondary displacement requiring closed reduction or internal fixation under general anaesthesia at the 1-week follow-up visit. ⋯ II, prospective observational study.

Impact of preoperative varus deformity on postoperative mechanical alignment and long-term results of "mechanical" aligned total knee arthroplasty.
Preoperative varus deformity may affect postoperative mechanical alignment and outcomes of total knee arthroplasty (TKA). In this study, we aimed to determine whether (1) greater degrees of preoperative varus deformity increase the incidence of varus-aligned TKAs and (2) residual varus alignment improves the long-term survival rate in TKAs with preoperative varus deformity. ⋯ III, Retrospective comparative cohort study.
