Observational StudyPerioperative vitamin D levels correlate with clinical outcomes after ankle fracture fixation.
Hypovitaminosis D is common in patients undergoing orthopaedic trauma surgery. While previous studies have shown that vitamin D levels correlate with functional outcome after hip fracture surgery, the significance of vitamin D levels on outcomes after surgery in other orthopaedic trauma patients is unknown. The purpose of this study was to determine if vitamin D levels correlated with outcomes in ankle fracture patients. ⋯ In our group of patients with operative treated ankle fractures, preoperative vitamin D deficiency correlated with inferior clinical outcomes at a minimum of 1 year follow-up. Our study suggests that deficient vitamin D levels may result in worse outcomes in orthopaedic trauma patients recovering from fracture fixation.

Comparative StudyVarus and valgus stress tests after total knee arthroplasty with and without anesthesia.
Retrospective studies demonstrated inadequate soft tissue balance is associated with the long-term outcome of total knee arthroplasty (TKA). However, most of these studies have evaluated the joint laxity only postoperatively without anesthesia. Therefore information about the effect of anesthesia on knee laxity is important for soft tissue balancing at the time of surgery. This study was conducted to determine how anesthesia affects the varus and valgus stress tests after TKA. ⋯ Anesthesia significantly influenced knee joint laxity after TKA. The findings of this study suggest that muscular forces impart a stabilizing force across the joint.

Comparative StudyComparison of retrograde nailing and minimally invasive plating for treatment of periprosthetic supracondylar femur fractures (OTA 33-A) above total knee arthroplasty.
Retrograde intramedullary (IM) nailing and minimally invasive plate osteosynthesis (MIPO) using locking plate are typically considered the gold standards of treatment for periprosthetic supracondylar femoral fractures above total knee arthroplasty (TKA). ⋯ Although retrograde nailing was found to have a slightly higher rate of malunion compared to minimally invasive plating, there was no statistically significant difference between both treatment options in terms of clinical outcomes. Regardless of which implant is used, the proper application is essential in management of periprosthetic supracondylar femoral fractures above TKA.

Case ReportsPathological fracture of the patella due to an atypical located aneurysmal bone cyst: verification by means of ultrasound-guided biopsy.
We report on a rare case of an atypical located aneurysmal bone cyst (ABC) in the patella presenting with pathological fracture after trauma. ⋯ As shown in this rare case of an atypical aneurysmal bone cyst of the patella, the quite seldom but sometimes possible ultrasound-guided biopsy of intraosseous lesions can help to achieve the diagnostic clarification and should also be taken into account as a non-standard procedure.

Increased risk for extended acetabular reconstruction in failed hip resurfacing as compared to failed total hip arthroplasty.
Hip resurfacing (HR) is intended to preserve the femoral bone stock during primary arthroplasty. On the other hand, little has been reported regarding the intraoperative need of bone reconstruction for extended acetabular defects during hip resurfacing revision. Thus, the aim of the presented study was to identify whether there is an increased need for acetabular bone reconstruction in HR revision surgery. ⋯ This study provides evidence that revision of failed HR devices is associated with an increased risk for extensive acetabular defects. Furthermore, the preoperative radiographic assessment of HR devices often underestimates the intraoperative acetabular defect. Surgeons should be aware of this fact not to technically underestimate HR revision procedures.
