Hand wounds: An analysis of topography and related damage to underlying structures.

Introduction: Hand wounds account for 35 to 51% of hand traumas. Damage to underlying anatomical structures depends on the location of the wound. The objective of this study is to describe the topographic distribution of hand wounds allowing for subsequent evaluation of the link between affected surface area and underlying lesion.

A Study of Hand Flap Viability when Using a Wide Awake Local Anesthesia No Tourniquet (WALANT) Technique.

 Flap surgery using a wide awake local anesthesia no tourniquet (WALANT) technique has historically been avoided because of technical challenges and concerns regarding the vasoconstriction caused by the necessary injection of epinephrine alongside the local anesthetic. The objective of our work was to evaluate the viability of the hand flaps performed using a WALANT technique compared with those performed under regional with a tourniquet.  Seventy-four patients were enrolled in a prospective comparative single-center study and subsequently divided into two groups: 36 patients in the locoregional anesthesia group and 38 patients in the WALANT group.

Novel robotic technology for the rapid intraoperative manufacture of patient-specific instrumentation allowing for improved glenoid component accuracy in shoulder arthroplasty: a cadaveric study.

Background: Accurate prosthesis placement in arthroplasty is an important factor in the long-term success of these interventions. Many types of guidance technology have been described to date often suffering from high costs, complex theater integration, time inefficiency, and problems with day-to-day usability. We present a novel, intraoperative robotics platform, capable of rapid, real-time manufacture of low-cost patient-specific guides while overcoming many of the issues with existing approaches.

Mixed Reality Assisted Percutaneous Scaphoid Fixation: A Proposed New Surgical Technique.

The success of percutaneous fixation of non or minimally displaced scaphoid waist fractures is reliant on optimal placement of the screw. This can be challenging for surgeons to achieve, potentially involving a large volume of intraoperative imaging, and surgical time. Mixed reality (MR) is a new technology that allows the projection of holographic imagery within the surgeon's field of vision intraoperatively.

The Glenoid Vault Outer Cortex a new more accurate radiological reference for shoulder arthroplasty.

Introduction: Correct positioning of the glenoid component is an important determinant of outcome in shoulder arthroplasty. We describe and assess a new radiological plane of reference for improving the accuracy of glenoid preparation prior to component implantation - the Glenoid Vault Outer Cortex (GvOC) plane.

Methods: One hundred and five CT scans of normal scapulae were obtained.

Os acromiale: a review of its incidence, pathophysiology, and clinical management.

An os acromiale occurs when any of the primary ossification centres of the acromion fail to fuse with the basi-acromion. It is present in approximately 8% of individuals, and whilst the majority of these individuals are unaffected it can cause significant pain and disability. It can impact seemingly unrelated surgical intervention in the region such as subacromial decompression and reverse shoulder arthroplasty.

Occult myometrial recurrence after progesterone therapy to preserve fertility in a young patient with endometrial cancer.

Objective: We report a case of endometrial cancer treated by fertility-preserving P therapy, who subsequently presented with an abnormal magnetic resonance imaging (MRI) of the myometrium despite normal endometrial biopsies.

Design: Case report.

Setting: Tertiary referral university hospital.
