Rod Link Reducer system in adolescent idiopathic scoliosis: a retrospective observational trial.

Purpose: The Rod Link Reducer (RLR) (Globus Medical, PA, USA) allows direct three-dimensional correction of the spine deformity follows the direct vertebral rotation (DVR) theories. The purpose of this retrospective study is to compare RLR with traditional correction technique (TCT) in two cohorts of patients with adolescent idiopathic scoliosis (AIS).

Methods: Fifty-four patients (M:F = 1:8) between 2018 and 2020 were included.

Fourth generation head fracture in ceramic-on-polyethylene bearing after hip revision surgery: a case report.

Fourth generation ceramic bearings (BIOLOX delta, CeramTec AG; Phlochingen, Germany) were developed to reduce wear debris and improve fracture resistance. A case of a fourth generation head fracture in ceramic-on-polyethylene (COP) coupling after hip revision surgery is reported. A 58-year-old man was admitted to our department for increasing hip pain following a direct trauma which occurred during skiing activity 4 months before.

Direct anterior total hip arthroplasty: a retrospective study.

Background: The quest for less invasive surgical approaches for total hip arthroplasty has gained much attention recently. There is very little information regarding differences about the main surgical access. The purpose of this study was to collect data regarding patients' subjective perceptions of the direct anterior hip arthroplasty, heterotopic ossification degrees, range of movement and complication and comparing these satisfaction results with the other surgical techniques.

Incomplete, stable-like, peri-prosthetic Vancouver B fracture around an ha-coated stem. Is there a case for strategic thoughtful neglect?

The Periprosthetic fracture of the proximal femur is usually treated by internal fixation of the fracture or revision of the femoral stem depending on the characteristics of the fracture and stability of the implant. This case report shows an early periprosthetic fracture around an uncemented straight stem which is treated conservatively with an excellent clinical radiographic result and explains the biomechanics related to this non-operative choice. A conservative treatment of periprosthetic fracture is possible but only after a careful analysis of the fracture pattern, the characteristics of the prosthetic stem and the time elapsed from implanting the prosthesis to the fracture.
