Analysis of bone union after medial closing wedge distal femoral osteotomy using a new radiographic scoring system.
To compare bone union after medial closing wedge distal femoral osteotomy (MCWDFO) with that after lateral closing wedge distal femoral osteotomy (LCWDFO) using a novel scoring system. ⋯ Bone union progression was slower and hinge fractures were more frequently observed after MCWDFO than after LCWDFO via DLO. MCWDFO is technically challenging, and patients must be monitored closely during and after surgery.

The Olympia anatomic polished cemented stem is associated with a high survivorship, excellent hip-specific functional outcome, and high satisfaction levels: follow-up of 239 consecutive patients beyond 15 years.
The Olympia femoral stem is a stainless steel, anatomically shaped, polished and three-dimensionally tapered implant designed for use in cemented total hip arthroplasty (THA). The primary aim of this study was to determine the long-term survivorship, radiographic outcome, and patient-reported outcome measures (PROMs) of the Olympia stem. ⋯ The Olympia stem demonstrated excellent 10-year PROMs and very high rates of stem survivorship at final follow-up beyond 15 years.

Metallosis after using distal fibular locking plate for lateral malleolar fractures: a retrospective study.
Studies regarding the development of metallosis following open reduction and internal fixation (ORIF) of fractures are rarely found in orthopedic literature. The aim of the current study was to assess metallosis following ORIF using distal fibular locking plates to treat distal fibular fractures. ⋯ In our study, metallosis developed more than was previously known, particularly after using LCPs to treat lateral malleolar fractures. Our findings and those in recent publications support the possibility that metallosis can occur not only in patients with arthroplasties, but also in patients with open reduction and internal fixation with LCPs. Surgeons should be aware of such risk of metallosis and be careful to select proper plates for internal fixation.

Mid-term implant survival, functional and radiological results and mechanical complications of mega-prosthetic reconstruction around the knee with the PENTA® system.
Mega-prosthetic reconstruction is the most common treatment method for massive osteoarticular defects caused by tumor resection around the knee. The new implant is a highly modular rotational-hinged megaprosthesis system with a distinct pentagonal stem geometry and variable implantation options. The aim of this study is to present the mid-term implant survival characteristics, functional and radiological results and mechanical complication profile of the new megaprosthesis. ⋯ The new megaprosthesis system is a reliable choice for the reconstruction of tumor-related massive osteoarticular defects around the knee. Although long-term follow-up is necessary for a definitive evaluation of the implant's survival characteristics, midterm follow-up yields exceptional anchorage properties related to pentagonal stem geometry with very good functional outcomes.

Reduction of olecranon fractures with no or minimal dorsal cortex comminution based on the contour of the posterior ulnar cortex: does it restore the greater sigmoid notch?
When treating olecranon fractures surgically, surgeons rely on the contour of the posterior cortex of the proximal ulna. However, it is unclear whether the greater sigmoid notch (GSN) is restored anatomically by this method. We analyzed whether reduction of fractures based on the posterior ulnar cortex contour is reliable for restoration of the GSN contour in displaced olecranon fractures with no or minimal dorsal cortex comminution. ⋯ IV.
