Impact of haptic feedback on surgical training outcomes: A Randomised Controlled Trial of haptic versus non-haptic immersive virtual reality training.

Objective: This study aimed to evaluate the educational impact of integrated haptic feedback in an immersive VR bone drilling simulation on the performance of a cohort of junior surgeons.

Design: Block randomised, controlled, double-blinded study.

Setting: St Georges University Hospital, London, United Kingdom.

Using Haptic Feedback in a Virtual Reality Bone Drilling Simulation to Reduce Plunge Distance.

Background Bone drilling is a procedure that demands a high level of dexterity, fine motor skills and spatial awareness from the operating surgeon. An important consideration when drilling bone is minimising soft tissue damage. There are numerous causes of drilling associated soft tissue injury, of which most concerning is drilling into the tissue beyond the far cortex as unseen injury can occur.

The adoption of an e-learning system using information systems success model: a case study of Jazan University.

Background: The e-learning system has gained a phenomenal significance than ever before in the present COVID-19 crisis. The E-learning delivery mechanisms have evolved to enhanced levels facilitating the education delivery with greater penetration and access to mass student population worldwide. Nevertheless, there is still scope to conduct further research in order to innovate and improve higher quality delivery mechanism using the state-of-the-art information and communication technologies (ICT) available today.

Salvage Procedures for Management of Prosthetic Joint Infection After Hip and Knee Replacements.

Background: The increasing load placed by joint replacement surgery on health care systems makes infection, even with the lowest rates, a serious concern that needs to be thoroughly studied and addressed using all possible measures.

Methods: A comprehensive review of the current literature on salvage procedures for recurrent PJIs using PubMed, EMBASE and CINAHL has been conducted.

Results: Prolonged suppressive antibiotic therapy (PSAT), resection arthroplasty and arthrodesis were the most common procedures performed.

High rates of sexual and urinary dysfunction after surgically treated displaced pelvic ring injuries.

Background: Pelvic ring injuries may be associated with genitourinary injury (GUI) and result in urinary or sexual dysfunction.

Questions/purposes: We determined (1) incidence of new sexual and urinary dysfunction after surgically treated pelvic ring injuries, (2) association of sexual or urinary dysfunction to fracture type and GUI, and (3) incidence and association between new sexual and urinary dysfunction in male and female patients without GUI.

Methods: We retrospectively studied 151 patients by postal questionnaire after pelvic reconstruction.

In vitro pressurization of the acetabular cement mantle: the effect of a flange.

A model was developed to assess the effect of an acetabular flange on pressure within different zones of the cement mantle during insertion. Two prosthetic designs were assessed in 3 different sizes. Flanged components produced significantly higher mean pressures than unflanged ones (P < .
