Burnout in New Zealand resident doctors: a cross-sectional study of prevalence and risk factors.

Objective: Burnout syndrome, characterised by emotional exhaustion, depersonalisation and decreased personal accomplishment, is well documented in the medical workforce. This study aimed to investigate the prevalence of burnout in New Zealand resident doctors (doctors who have yet to complete their specialty training).

Design: Cross-sectional survey study of resident doctors in New Zealand.

Positive and negative framing of complication risk and long-term outcomes influences decision-making in hip and knee arthroplasty.

Background: The framing effect has been demonstrated in a variety of settings. This study aimed to determine whether framing of complication risk in total hip arthroplasty (THA) and long-term patient satisfaction rates in total knee arthroplasty (TKA) influences patient decision-making and 'worry' using hypothetical vignettes.

Methods: Two cross-sectional survey studies were undertaken, one based on a THA vignette and one based on a TKA vignette.

A comparison of orthopaedic surgery training across five English-speaking countries.

Introduction: There is undocumented and unjustified variability in orthopaedic surgery training between countries. This study compares and contrasts the main features of orthopaedic training in Australia, New Zealand, the United Kingdom, United States, and Canada.

Methods: Comparisons included: competition for, and selection into, training; training pathway structures; training requirements, and; training length.

Increasing venture capital investment in spinal surgery: an analysis of investments from 2000 to 2023.

Background Context: Venture capital (VC) plays a vital role in advancing spinal surgery technologies, driven by the growing burden of spinal disorders and high healthcare costs. Despite increasing interest, trends in VC funding for spinal surgery remain understudied.

Purpose: This study aimed to examine temporal and thematic trends in VC investments in spinal surgery companies from 2000 to 2023.

Unnecessary care in orthopaedic surgery.

Unnecessary care, where the potential for harm exceeds the potential for benefit, is widespread in medical care. Orthopaedic surgery is no exception. This has significant implications for patient safety and health care expenditure.

Equivalent revision rates and patient reported outcomes with routine use of a short (125mm) cemented stem for total hip arthroplasty compared to a standard length (150mm) cemented stem. A two surgeon series of 1335 patients.

Background: Routine total hip arthroplasty (THA) using a short cemented stem as compared with a standard length cemented stem may have benefits in terms of stress distribution, bone preservation, stem subsidence and ease of revision surgery. Two senior arthroplasty surgeons transitioned their routine femoral implant from a standard 150 mm Exeter V40 cemented stem to a short 125 mm Exeter V40 cemented stem for all patients over the course of several years. We analysed revision rates, adjusted survival, and PROMS scores for patients who received a standard stem and a short stem in routine THA.

Classification system for partial distal biceps tendon tears: a descriptive 3-Tesla magnetic resonance imaging study of tear morphology.

Background: There is minimal literature on the morphology of partial distal biceps tendon (DBT) tears. We sought to investigate tear morphology by retrospectively reviewing 3-Tesla magnetic resonance imaging (3T MRI) scans of elbows with partial DBT tears and to propose a basic classification system.

Methods: 3T MRI scans of elbows with partial DBT tears were retrospectively reviewed by two experienced observers.

Localization within Hostile Indoor Environments for Emergency Responders.

Recent advances in techniques to improve indoor localization accuracy for personnel and asset tracking challenges has enabled wide-spread adoption within the retail, manufacturing, and health care industries. Most currently deployed systems use distance estimates from known reference locations to localize a person or asset using geometric lateration techniques. The distances are determined using one of many radio frequency (RF) based ranging techniques.

Defining the proximity of the axillary nerve from defined anatomic landmarks: an in vivo magnetic resonance imaging study.

Background: The location of the axillary nerve in the shoulder makes it vulnerable to traumatic or iatrogenic injury. Cadaveric studies have reported the location of the axillary nerve but are limited because of tissue compression, dehydration, and decay. Three-Tesla (T) magnetic resonance imaging (MRI) allows high anatomic resolution of neural structures.

Dedicated training program for shoulder sonography: the results of a quality program reverberate with everyone.

Objectives: The purpose of this study was to define and report on the effect of a comprehensive musculoskeletal sonography training program to improve accuracy (sensitivity and specificity) for the diagnosis of rotator cuff tears in relatively inexperienced operators.

Methods: Before the training program was implemented, radiologists (n = 12) had a mean of 2 years (range, <1-12 years) of experience performing and interpreting musculoskeletal sonography. Pre- and post-training shoulder sonographic results were compared to surgical reports or, in their absence, to shoulder magnetic resonance imaging or computed tomographic arthrographic results if within 2 months of the sonographic examination.
