Treatment of acetabular fractures remains one of the most challenging tasks that orthopaedic surgeons face. An accurate assessment of the injuries and preoperative planning are essential for an excellent reduction. The purpose of this study was to evaluate the feasibility, accuracy and effectiveness of performing 3D printing technology and computer-assisted virtual surgical procedures for preoperative planning in acetabular fractures. We hypothesised that more accurate preoperative planning using 3D printing models will reduce the operation time and significantly improve the outcome of acetabular fracture repair. ⋯ The 3D printing technology combined with virtual surgery for acetabular fractures is feasible, accurate, and effective leading to improved patient-specific preoperative planning and outcome of real surgery. The results provide useful technical tips in planning pelvic surgeries.

Adequate exposure is fundamental to safely and correctly perform open procedures around the knee. Tibial tubercle osteotomy (TTO) has previously been described as a method to improve exposure, particularly in complex primary elective knee arthroplasty or revision surgery. We describe a tibial tubercle osteotomy technique to improve exposure in complex knee fractures and a cadaveric study and trauma case series.

Necrosis of the humeral head, infections and non-unions are among the most dangerous and difficult-to-treat complications of proximal humeral fractures. The aim of this work was to analyse in detail non-unions and post-traumatic bone defects and to suggest an algorithm of care. ⋯ This method enables the surgeon to choose the most suitable treatment for the patient, thereby facilitating return of function in the shortest possible time. The treatment of such serious complications requires the surgeon to be knowledgeable about the following possible solutions: increased mechanical stability; biological stimulation; and reconstructive techniques in two steps, with application of biotechnologies and prosthetic substitution.

To quantify and compare the incidence of lower extremity injuries in skiers and snowboarders who present to emergency rooms in the United States. ⋯ The incidence of lower extremity injuries in skiers was higher than that of snowboarders in 2014, with the 0-19year old age group and males being those most likely to sustain an injury. The most common region of the lower extremity that was injured was the knee for skiers and the lower trunk (e.g. pelvis, hip, lumbar spine) for snowboarders. Physicians and consumers alike should be aware of this data when considering participation in these sports as well as strategies for injury prevention.

Soft tissue defects of the digits are very common in hand trauma and can result in functional disability. The purpose of the study is to introduce the use of several modified and traditional sensate flaps to reconstruct different regions of the digits and to evaluate the efficacy of these techniques. ⋯ Compared to single-innervated flap, dual-innervated flap exhibited better sensory recovery and lower pain incidence. Being an additional treatment option, Littler flap may be better choice for sensory coverage in some specific situations including border injuries.
