Combined proximal tibial osteotomy (CPTO) is an innovative and effective procedure for correcting varus knee osteoarthritis (VKOA) with intra- and extra-articular deformity. Here, we designed a novel internal fixation plate system for CPTO and assessed the biomechanical strength of the bone-implant. ⋯ The novel internal fixation plate system usage during CPTO exhibited similar bone-implant biomechanical strength, compared to OWHTO, but with enhanced construct stability.

The establishment of national trauma networks have resulted in significant benefits to injured patients. Older people are the majority of major trauma patients and there is need to study variations in care and performance against clinical metrics for them. We aim to describe this patient group in terms of injury, demographics, episode of care assessment and variation between component regions of the Major Trauma Network of England and Wales. ⋯ We have increased the understanding of how older patients contribute to and are managed by a national trauma service. We have demonstrated variation in numbers and patient characteristics throughout regional trauma networks. We have detailed the whole patient episode, allowing us to comment on disparities in management such as senior review and access to specialist clinical care settings. Older patients dominate United Kingdom major trauma and considerable variations and shortfalls have been identified. Work is needed to focus on the whole clinical episode for these patients both to improve outcome and patient experience but to also to ensure sustainable clinical care in a resource deplete era.

Management of soft tissue defects around the ankle is a difficult and challenging situation for all reconstructive surgeons. A microsurgical free flaps coverage can solve this problematic situation especially with large defects that is not available in all trauma centers. Moreover, long operating time and suitable operative demands are considered obstacles. ⋯ Many treatment options are available to cover defects around the ankle. Propeller and rotational flaps are fast and easy but cover small defects, distally-based modified sural artery flap is an excellent reliable flap. Microsurgical free flaps provide good contour, color, texture and cover large defects but require microsurgery facilities to execute.

Periprosthetic femoral fracture (PFF) is well-known complication in cementless hip arthroplasty (HA), especially in the elderly with osteoporosis. To prevent intraoperative PFFs during HA, prophylactic cerclage wiring on the calcar area during femoral broaching and implant insertion is recommended. However, biomechanical data on the benefits of cerclage wiring in osteoporotic bone during impaction are limited and controversial. This study aimed to assess the efficacy of prophylactic double-looped cerclage wiring (PDLCW) during femoral broaching in the osteoporotic bone model with an impaction simulation system. ⋯ This study showed that PDLCW significantly improved hoop stress resistance by increasing the calcar fracture threshold related to mallet impaction, decreasing the risk of complete calcar fracture.
