Surgical Predictive Model for Breast Cancer Patients Assessing Acute Postoperative Complications: The Breast Cancer Surgery Risk Calculator.

Background: Prognostic tools, such as risk calculators, improve the patient-physician informed decision-making process. These tools are limited for breast cancer patients when assessing surgical complication risk preoperatively.

Objective: In this study, we aimed to assess predictors associated with acute postoperative complications for breast cancer patients and then develop a predictive model that calculates a complication probability using patient risk factors.

Femur flap for tibial reconstruction: percent circumference required to convey a mechanical advantage over the fibula.

The fibula flap is commonly used to reconstruct the tibia. This has risk of postoperative fracture despite long-term non-weight bearing. A flap using noncircumferential distal femur is proposed.

Salvage of a lower extremity by microsurgical transfer of tibial bone from the contralateral extremity traumatically amputated at the ankle level.

The authors present a case of free vascularized transfer of the tibial bone as an osteomyocutaneous flap based on the posterior tibial vessels. A 42-year-old man presented with severe crush injury to bilateral legs. The left tibial bone and soft tissue defect required reconstruction with an osteomyocutaneous free flap.

Characterization of forces on the sternal midline following median sternotomy in a porcine model.

The development of more effective fixation devices for reapproximating and immobilizing the sternum after open-heart surgery is limited by current methods for evaluating these devices. In particular, precise emulation of in vivo sternal loading has not been achieved in controlled model systems. The present study is an initial effort to determine the in vivo loading parameters needed to improve current in vitro and in silico (computational) models.

Popliteal vein aneurysm: a case report and review of literature.

The authors report a case of popliteal vein aneurysm (PVA) in a healthy patient who presented with symptoms and review the literature. A 40-year-old healthy male presented with hypoxia secondary to pulmonary emboli. He underwent diagnostic tests revealing a suprageniculate saccular PVA, which was treated by aneurysmectomy and lateral venorrhaphy.

Management of incidental fibrous dysplasia of the maxilla in a patient with facial fractures.

We present the case of a 53-year-old man who was involved in a motor vehicle accident. A maxillofacial computed tomography scan revealed a large tumor of the left maxilla as well as multiple facial fractures. The tumor extended from the palate to the orbital floor and from the medial to the lateral wall of the maxillary sinus.

Venous supercharging of heterodigital artery flap.

Background: The heterodigital artery island flap is a popular method of reconstruction for finger defects. Postoperative venous congestion is a common problem.

Methods: The authors present a technique to augment venous drainage of the flap.
