Reaming in treatment of non-unions in long bones: cytokine expression course as a tool for evaluation of non-union therapy.
The analysis of peripheral serum cytokine expression patterns has been shown to be a possible method for demonstrating changes in bone metabolism. The aim of this study is to evaluate the effectiveness of this method within the treatment of long bone non-union with intramedullary reaming, a well-established non-union treatment concept. ⋯ Our study was able to show that the cytokine expression pattern in physiological bone healing is similar to that in successful non-union treatment with intramedullary reaming. Our results show that the effect of non-union therapy could be observed objectively by measuring cytokine expression patterns in peripheral blood even in a small group of patients.

Ligament reconstruction with single bone tunnel technique for chronic symptomatic subtle injury of the Lisfranc joint in athletes.
Only few procedures for Lisfranc ligaments reconstruction to treat subtle injury of the Lisfranc joint have been reported. We have developed a novel technique for Lisfranc ligaments reconstruction, which was applied to treat chronic symptomatic subtle injuries that had failed to respond to initial treatment or were misdiagnosed. This article describes the technique and its operative outcome in a small case series. ⋯ Level IV, retrospective case series.

Unicompartmental knee arthroplasty in patients with full versus partial thickness cartilage loss (PTCL): equal in clinical outcome but with higher reoperation rate for patients with PTCL.
While the classical indications and contraindications for unicondylar knee arthroplasty (UKA) are widely accepted there is not yet consensus if patients with partial thickness cartilage loss (PTCL) are equally suited for treatment with UKA. The aim of our study was to determine if patients with partial thickness cartilage loss do equally well after treatment with UKA. ⋯ Patients with PTCL are not equally suited for treatment with UKA like patients with bone on bone. Although PTCL has equal clinical results, it was associated with higher revision rates in our series.

Is there a rationale to use a dual mobility poly insert for failed Birmingham metal-on-metal hip replacements? A retrieval analysis.
Previous studies showed poor outcomes for patients undergoing revision of failed metal-on-metal total hip arthroplasty (MoM-THA) and resurfacing (RS) with an increased risk of dislocation. Dual mobility inserts are an option to retain the acetabular component and change the metal-on-metal bearing to plastic-on-metal. The current study analyzes the rationale for the off-label use of a dual mobility poly insert (MDM X3, Stryker, Mahwah, NJ) in a Birmingham metal shell (Smith & Nephew, Memphis, TN). ⋯ Clearances of the MDM poly insert in a BHR shell are reduced, and although the majority of combinations appear safe, the indication needs to be made on an individual base carefully considering alternative treatment options.

The effect of tibial slope in acute ACL-insufficient patients on concurrent meniscal tears.
The aim of this study is to evaluate the effect of the medial and lateral posterior tibial slope (MPTS, LPTS) in patients with acutely ruptured ACL on the menisci. It was hypothesized that medial and lateral meniscus lesions are seen more often with high PTS (posterior tibial slope). We hypothesized that in case of a high tibial slope a possible meniscus lesion is more often located in the posterior horn of the meniscus than in knees with a low tibial slope. ⋯ IV.
