Pins and rubbers traction system for fractures of the proximal interphalangeal joint.
We aimed to evaluate the clinical results using the pins and rubbers traction system (PRTS) as described by Suzuki et al. for unstable intra-articular fractures of the proximal interphalangeal (PIP) joint and to assess the efficacy and the indication of the technique of the PRTS. ⋯ The current study demonstrated good results of the PRTS for unstable intra-articular fractures of the PIP joint. Furthermore, satisfactory results were obtained in cases of an incomplete amputation at the PIP joint, a pathological fracture due to bone tumor, and an osteochondral defect due to comminuted fracture of the proximal phalangeal head, where costal osteochondral bone was transplanted. From this study, the PRTS is recommended as a useful treatment because it is widely effective for various unstable fractures of the PIP joint.

Severe varus knees result in a high rate of undercorrection of lower limb alignment after opening wedge high tibial osteotomy.
The purpose of this study was to clarify the indication for opening wedge high tibial osteotomy (OWHTO) in terms of lower limb alignment to achieve satisfactory clinical results. ⋯ Based on these results, we recommend that a preoperative FTA of <185° should be included as a criterion for OWHTO alone.

Comparative StudyClinical outcomes of dual 3.5-mm locking compression plate fixation for humeral shaft fractures: Comparison with single 4.5-mm locking compression plate fixation.
Recently, several in vitro biomechanical studies that used dual small locking plate fixation for humeral shaft fractures have investigated. However, in vivo studies about dual plate fixation for humeral shaft fractures are limited. The purpose of our study was to report the outcomes of dual small plating for humeral shaft fractures in comparison with those of single large fragment plating. ⋯ For diaphyseal humeral fractures, dual 3.5-mm LCP fixation to the humerus is a possible treatment choice. This method showed satisfactory union rate, ROM, and complication rate, without increasing surgical time, in comparison with the conventional single 4.5-mm LCP fixation. Level of evidence: III.

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.
