Comparative Study
New classification focusing on implant designs useful for setting therapeutic strategy for periprosthetic femoral fractures.
In periprosthetic femoral fractures, our hypothesis was that when the bone and implant are stable, the fracture does not occur at the biologic or cement fixation regions but occurs at the no fixation region. The aim of this study was to investigate the validity of our new classification for periprosthetic femoral fractures and compare reliability of radiographic evaluation for implant stability between our classification and the Vancouver classification. ⋯ Our classification is based on a completely new concept and was prepared to overcome periprosthetic femoral fracture failures by objective evaluation. We believe this new classification is useful to establish a therapeutic strategy for femoral fractures around the stem.

Total hip arthroplasty (THA) in the presence of developmental dysplasia of the hip (DDH) presents many challenges to the reconstructive surgeon. The complexity of femoral and acetabular anatomy in these cases makes standard reconstruction technically challenging. Restoring the anatomic centre of hip rotation may require femoral osteotomy. The aim of this study was to determine the rate of union, complications and functional results in a series of patients with Crowe IV dysplastic hips who underwent cementless THA and simultaneous subtrochanteric oblique osteotomy. ⋯ Combined subtrochanteric femoral osteotomy and cementless THA is technically demanding and proved to be safe and effective in femoral shortening for treatment of Crowe IV DDH.

Although injuries sustained during ice skating have been reported to be more serious than other forms of skating, the potential injury risks are often underestimated by skating participants. The purpose of this study was to give a descriptive overview of injury patterns occurring during ice skating. Special emphasis was put on injury severity by using a standardised injury classification system. ⋯ The severity of ice-skating injuries is associated with the patient's age, showing more severe injuries in older patients. Awareness should be raised among the public and physicians about the risks associated with this activity in order to promote further educational interventions and the use of protective gear.

The aim of this study was to survey existing literature in order to identify all reported predictors associated with nonunion or symptomatic malunion in adult patients with displaced midshaft clavicle fractures treated non-operatively. ⋯ The included publications varied greatly in design, sample size, and quality. Based on the present literature most of the predictors were found to be of limited evidence, however displacement seems to be the most likely factor that can be used to predict for nonunion. Treating all clavicle fractures with displacement surgically would inevitably lead to overtreatment, which is why future studies need to focus on predictive factors in order to differentiate between patients that would benefit from surgery and those who would not.

Revision of failed total hip arthroplasty with massive acetabular bone loss resulting in pelvic discontinuity represents a rare but challenging problem. The objective of this study was to present short to mid-term results of revision total hip arthroplasty with a custom-made acetabular implant in a consecutive series of patients with pelvic discontinuity. ⋯ Treatment of acetabular bone loss and pelvic discontinuity with a custom-made acetabular component can provide a durable solution with good clinical and radiographic results.
