Quantitative evaluation of residual bony impingement lesions after arthroscopic treatment for isolated pincer-type femoroacetabular impingement using three-dimensional CT.
The objective of this study is to determine the clinical characteristics of residual bony impingement lesions after arthroscopic treatment for pincer-type femoroacetabular impingement (FAI); and to determine the effects of residual bony impingement lesions on the clinical outcomes after 2 years of follow-up. ⋯ The incidence of residual impingement lesions after arthroscopic pincer-type FAI correction was 63.3 %. The residual rate was 14.48 %. The residual impingement lesions were primarily in the posterior portion of the acetabulum. The clinical outcomes were associated with the residual rate of bony impingement lesions. The patients with residual rates >20 % exhibited significantly lower clinical scores and satisfaction rates.

Comparative StudyIsocentric C-arm three-dimensional navigation versus conventional C-arm assisted C1-C2 transarticular screw fixation for atlantoaxial instability.
The Isocentric C-arm 3D navigation has been widely used in superior cervical surgeries in recent years. Several clinical researches reported that navigation system was an effective support device for treatment of atlantoaxial instability. But there were few studies about the advantages of navigation system compared to conventional C-arm fluoroscopy in C1-C2 transarticular screw fixation for atlantoaxial instability. The aim of the study was to evaluate the precision of computer-assisted C1-C2 transarticular screw fixation (Magerl's technique) for atlantoaxial instability and compare the clinical results with conventional C-arm fluoroscopy. ⋯ On comparing the two imaging techniques, it was found that using Iso-C 3D navigation can improve accuracy of the C1-C2 transarticular screws, decrease intra-operative fluoroscopic time and blood loss, and not prolong the operative time. This study demonstrates that Iso-C 3D navigation is a safe and effective means of guiding C1-C2 transarticular screw fixation for atlantoaxial instability.

Thermal necrosis induced by electrocauterization as a local adjuvant therapy in local aggressive bone tumors, what is the safe limit for surgical margins? An experimental study.
In the current study, it was aimed to investigate the temperature change in the cavity wall and pathologic necrosis occurred during cauterization, which was applied at different voltages and time intervals. ⋯ Experimental animal study, Level II.

Comparative StudyInfrapatellar fat pad preservation reduces wound complications after minimally invasive total knee arthroplasty.
The aim of this study was to determine whether pain intensity and wound complication rates differ between patients with and without preservation of the infrapatellar fat pad (IPFP) after minimally invasive total knee arthroplasty (TKA). The authors also sought to determine whether IPFP preservation affects operation time. ⋯ Although IPFP preservation delayed operation time, it decreased wound complications after MIS TKA. These findings are important to consider when deciding whether or not to resect the IPFP. Whenever possible, IPFP preservation is probably the preferred technique to reduce wound complications.

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.
