Uncemented extensive porous titanium-coated long femoral stem prostheses are effective in treatment of Vancouver type B2 periprosthetic femoral fractures: A retrospective mid- to long-term follow-up study.
The aim of this study was to evaluate the mid- to long-term outcomes of revision surgery for Vancouver type B2 periprosthetic femoral fractures (PFFs) after total hip arthroplasty using an uncemented extensive porous titanium-coated long femoral stem prosthesis (solution prosthesis) with or without cortical strut allograft. ⋯ Revision surgery using the solution prosthesis with or without cortical strut allograft is effective in treating Vancouver type B2 PFFs, with satisfactory mid- and long-term clinical and radiological outcomes.

Case ReportsAn aneurysmal bone cyst at T1 treated with bone grafts containing calcitonin and methylprednisolone.
Aneurysmal bone cysts (ABCs) rarely trigger pathological fractures. Various surgical and nonsurgical treatments have been reported for this condition. Herein, we present the examination findings and treatment for a 15-year-old girl who initially presented with adolescent idiopathic scoliosis and mild back pain, but subsequently experienced severe back pain. ⋯ At 3 years post-surgery, there was no ABC recurrence and only mild back pain persisted. To our knowledge, this is the first report of open surgery (curettage and fixation) with local intralesional administration of calcitonin and mPSL for an ABC-induced pathological spinal fracture. We believe that this treatment is an effective option for ABCs associated with a pathological spinal fracture.

A modified tarsal sinus approach for intra-articular calcaneal fractures.
Plate fixation using traditional lateral L-shape approach for intra-articular calcaneal fractures is complicated by 30% of wound complications, and the lateral small incision techniques with a tarsal sinus approach cannot sufficiently address all the fragments. A modified tarsal sinus approach with combined advantages of traditional lateral L-shape and tarsal sinus approaches for the treatment of intra-articular calcaneal fractures was developed. ⋯ The modified tarsal sinus approach in the treatment of Sander's type II and III calcaneal fractures allowed adequate reduction and rigid fixation with low incidence of wound complications. Compared to sinus tarsi approach, this technique required shorter learning curve and was more easily mastered by young orthopedic surgeons. Thus, it was worthy of application clinically.

An increase in the risk of excessive femoral anteversion for relatively younger age and types of femoral morphology in total hip arthroplasty with direct anterior approach.
Direct anterior approach (DAA) is known to diminish a dislocation risk and widely used for total hip arthroplasty (THA). On the other hand, anterior dislocation due to increasing stem anteversion and cup anteversion is an important complication. ⋯ The risk of excessive femoral anteversion increases for relatively younger age and for types of femoral morphology according to the Dorr classification, moreover with an increase of CA in DAA-THA with cementless tapered-wedge stem.

After-hours elective spine deformity corrective surgery for patients with Adolescent Idiopathic Scoliosis: Is it safe?
The aim of this study was to compare the outcome of after-hours electively planned Posterior Spinal Fusion surgeries for Adolescent Idiopathic Scoliosis (AIS) patients with daytime surgeries. ⋯ After-hours elective spine deformity corrective surgeries for healthy ambulatory patients with AIS were as safe as when they were done during daytime.
