The use of a dual-mobility concept in total hip arthroplasty patients with spastic disorders: no dislocations in a series of ten cases at midterm follow-up.
Total hip arthroplasty (THA) is one of the treatment options in patients with cerebral palsy (CP) with painful osteoarthritis of the hip. However, the risk of dislocation of the prosthesis is higher in patients with CP when compared with physically normal patients. In this retrospective study of ten consecutive cases, we hypothesized that the use of a dual-mobility cup could reduce this risk of dislocation combined with good functional results. ⋯ The use of a dual-mobility cup in THA in patients with CP can lead to favourable results with respect to dislocation and clinical outcome.

Intraoperative panoramic image using alignment grid, is it accurate?
Minimally invasive orthopedic trauma surgery relies heavily on intraoperative fluoroscopic images to evaluate the quality of fracture reduction and fixation. However, fluoroscopic images have a narrow field of view and often cannot visualize the entire long bone axis. ⋯ Panoramic images produced by stitching fluoroscopic images together with help of an alignment grid demonstrated the same accuracy at evaluating the coronal plane alignment of femur fractures as conventional X-rays.

Case ReportsHeterotopic ossification in portal sites following hip arthroscopy.
Heterotopic ossification (HO) is a well-known condition that usually occurs after head trauma, burns and open surgical procedures, most commonly around the hip and elbow joints. It is a well-documented complication occurring after open hip surgery; however, there exists limited information regarding its prevalence and clinical importance following hip arthroscopy. We report a case of symptomatic HO formation in portal sites following arthroscopic rim decompression, femoroplasty and labral debridement that was successfully treated with arthroscopic removal.

Traumatic and degenerative cartilage lesions: arthroscopic differentiation using near-infrared spectroscopy (NIRS).
Cartilage lesions or defects are the most common finding during knee arthroscopy. During arthroscopy, it is often difficult to differentiate between degenerative and traumatic cartilage lesions. The study aimed to determine the impact of near-infrared spectroscopy (NIRS) on the distinction between traumatic and degenerative cartilage lesions in the medial femoral condyle (MFC). It was hypothesized that NIRS as able to distinguish between traumatic and degenerative cartilage lesions. ⋯ After an injury, cartilage has a normal or nearly normal absorbance on near-infrared-light. Thus, it is possible to distinguish intraoperatively between traumatic and degenerative lesions. In addition, our results demonstrate that evaluating cartilage with NIRS is a dependable method for improving the diagnosis of significant chondral lesions.

Intramedullary nail versus extramedullary plate fixation for unstable intertrochanteric fractures: decision analysis.
The best options of internal fixation for unstable intertrochanteric femoral fractures in elderly osteoporotic patients remain controversial. We determined whether intramedullary nail or extramedullary plate provides better treatment for unstable intertrochanteric fractures using a decision analysis tool that considers quality of life. ⋯ In terms of quality of life, the decision analysis model showed that intramedullary nailing was more beneficial for patients with an unstable intertrochanteric fracture.
