Total Hip Arthroplasty (THA) after prior acetabular fracture repair is known to be demanding as studies have shown inferior implant survival rates and higher infection rates for these procedures. The direct anterior (DA) approach might help mitigate some of these risks by utilizing a new surgical tissue plane. However, potential criticisms of the DA approach for these surgeries include the inability to access previous acetabular implants or heterotopic ossification (HO) if they were to inhibit implant placement. The goals of this study are to analyze the efficacy of the DA approach for conversion to hip arthroplasty surgery after previous acetabular fixation. ⋯ This is the largest known cohort analyzing the DA approach for conversion to hip arthroplasty after previous acetabular fixation. Overall, we demonstrate that the DAA is safe for conversion THA after acetabular fixation.

The incidence of Lisfranc fractures is rising, along with the incidence of foot fractures in general. These injuries can lead to long-term healthcare use and societal costs. Current economic evaluation studies are scarce in Lisfranc fracture research, and only investigate the healthcare costs. The aim of the present study was to accurately measure the monetary societal burden of disease and quality of life in the first 6 months after the injury in patients with Lisfranc fractures in the Netherlands. ⋯ The total monetary societal costs in the first 6 months after injury are approximately €17,083. Approximately two thirds of these costs can be attributed to productivity losses. These costs appear to be somewhat higher than those found in other studies. However, these studies only included the healthcare costs. Furthermore, the baseline costs indicate relatively low healthcare usage before the injury compared to the average Dutch patient. The mean QoL index was 0.462 at baseline and 0.737 at 6 months, indicating a rise in QoL after treatment as well as a long-lasting impact on QoL. To our knowledge, this is only the first study investigating the societal costs of Lisfranc injuries, so more research is needed.

The distal radius fracture is a common fracture with a prevalence of 17% on the emergency departments. The conservative treatment of distal radius fractures usually consists of three to six weeks of plaster immobilization. ⋯ Due to upcoming innovations such as three-dimensional printed splints for distal radius fractures, a patient specific splint can be produced which may offer more comfort. Furthermore, these three-dimensional printed splints are expected to be more environmental friendly in comparison with traditional plaster casts.

Concerning rates of nonunion in articular distal humerus fractures indicate an unsolved problem. The fixation principles of O'Driscoll describe linking the fractured articular segment to the distal humerus columns with compression screws which creates a stable fixed angle construct. A novel device has been introduced which utilizes an interlocking beam through the articular segment to connect the distal aspect of the medial and lateral plates, creating a linked construct. We sought to evaluate the stability of this linked construct using an articular model of distal humerus fracture. ⋯ Our results indicate that an interlocking beam which links the medial and lateral plates provides greater stability compared to a similar construct without an interlocking beam. We attribute this finding to the beam's double supported design which resists cantilever bending and provides robust compression of the fractured fragments.

The Masquelet technique is a surgical procedure for the reconstruction of bone defects. During the first step, an osteosynthetically stabilized defect is filled with a cement spacer. The spacer induces a foreign body membrane, called a Masquelet membrane. In a follow-up procedure, the spacer is replaced by a bone graft, which ossifies in the subsequent phase. ⋯ With 171 patients and 195 septic bone defects treated at a single centre with the Masquelet Technique, this study represents a comparably large cohort. Demographics, defect characteristics and treatment outcomes did not differ from those of other cohorts described in the literature. Defects larger than 62 mm showed lower chances to reach full weight bearing and can be defined as "critical defect size" for the Masquelet technique based on our data.
