Long vs short intramedullary nails for reverse pertrochanteric fractures: A biomechanical study.

There is currently no definitive evidence for the implant of choice for the treatment of reverse pertrochanteric fractures. Here, we aimed to compare the stability provided by two implant options: long and short intramedullary nails. We performed finite element simulations of different patterns of reverse pertrochanteric fractures with varying bone quality, and compared the short vs long nail stabilization under physiological loads.

Role of the Gastrocnemius Musculocutaneous with a Propeller Style Skin Flap in Knee Region Reconstruction: Indications and Pitfalls.

 Soft tissue reconstruction around the knee area is still an open question, particularly in persistent infections and multiple reoperations scenario. Flap coverage should guarantee joint mobility and protection, even when foreign materials are implanted. The chimeric harvesting of the musculocutaneous gastrocnemius flap, based on the sural artery perforators, can extend its applicability in soft tissue reconstruction of the upper leg, overcoming the drawbacks of the alternative pedicled flaps.

Prosthetic fitting associated with better survival at 5 years after above-knee amputation due to vascular insufficiency.

Background: Individuals requiring non-traumatic Gritti-Stokes amputation or mid-thigh amputation usually have multiple comorbidities that place them at high risk of mortality.

Objective: To determine survival rate 5 years after Gritti-Stokes and mid-thigh amputation in individuals with vascular insufficiency and to identify the predictors of survival.

Methods: We conducted a retrospective observational study including all individuals with vascular insufficiency who underwent amputation from September 2007 to December 2015 in our University Hospital.

Locoregional anesthesia for post-operative pain management in microsurgical reconstruction of the lower extremities: A retrospective study.

Objective: Opioid-based analgesia is often used in the management of postoperative pain in arthroplasty cases. This article analyses the safety of single-shot peripheral nerve block (PNB) and potential analgesic benefits in patients undergoing lower limb free flap reconstruction.

Methods: A retrospective review including all patients undergoing lower limb reconstruction with free flaps between October 2017 and April 2020 was performed.

Effectiveness of an Online Course on Fracture-Related Infections.

This study aims to evaluate the effectiveness of an online course to enable orthopaedic surgeons to acquire the core competencies necessary to prevent and treat fracture-related infections (FRI). This study included orthopaedic surgeons and residents from Latin American countries who attended an online course focused on FRI. The online course included: didactic lectures, small-group clinical case discussions, and panel case discussions.
