Standard of care and outcomes for Māori patients with neck of femur fractures - an Australia & New Zealand Hip Fracture Registry (ANZHFR) study.

Background: This study aimed to compare the demographic differences between Māori and NZ Europeans with neck of femur fracture (NOF), identify any differences in management, surgical and post-op care and outcomes.

Methods: All cases in New Zealand between 2018 and 2020 were collected from the Australia & New Zealand Hip Fracture Registry (ANZHFR). Basic demographics, management factors, and surgical factors were collected.

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.

Comparing modern uncemented, hybrid and cemented implant combinations in older patients undergoing primary total hip arthroplasty, a New Zealand Joint Registry study.

Background: Multiple joint registries have reported better implant survival for patients aged > 75 years undergoing total hip arthroplasty (THA) with cemented implant combinations when compared to hybrid or uncemented implant combinations. However, there is considerable variation within these broad implant categories, and it has therefore been suggested that specific implant combinations should be compared. We analysed the most common contemporary uncemented (Corail/Pinnacle), hybrid (Exeter V40/Trident) and cemented (Exeter V40/Exeter X3) implant combinations in the New Zealand Joint Registry (NZJR) for patients aged > 75 years.

Comparing uncemented, hybrid and cemented primary total hip arthroplasty in young patients, a New Zealand Joint Registry study.

Background: Despite increasing use of uncemented implants in young patients undergoing total hip arthroplasty (THA), there is minimal evidence for specific implant combinations in this group. We analysed the most commonly used uncemented (Corail-Pinnacle), hybrid (Exeter-Trident/Tritanium), and fully cemented (Exeter) implant combinations in the New Zealand Joint Registry (NZJR) in patients aged under 40 and between 40 and 55 years.

Methods: All THAs recorded in the NZJR between 1999 and 2018 were included.

How do cemented short Exeter stems perform compared with standard-length Exeter stems? The experience of the New Zealand National Joint Registry.

Background: The standard Exeter (Stryker) cemented stem is 150 mm long with standard offsets ranging from 37.5 mm to 56 mm. Exeter short stems of 125 mm are also available in the offsets of 37.

Does preoperative mental health affect length of hospital stay and functional outcomes following arthroplasty surgery? A registry-based cohort study.

Aim: It has been reported in the literature that patients with poor preoperative mental health are more likely to have worse functional outcomes following primary total hip and knee arthroplasty. We could find no studies investigating whether preoperative mental health also affects length of hospital stay following surgery. The aim of this study was to determine whether preoperative mental health affects length of hospital stay and long-term functional outcomes following primary total hip and knee arthroplasty.

Surgical workload of a foreign medical team after Typhoon Haiyan.

Background: On 8 November 2013, Typhoon Haiyan struck the Philippines causing widespread loss of lives and infrastructures. At the request of the Government of the Philippines, the Australian Government deployed a surgical field hospital to the city of Tacloban for 4 weeks. This paper describes the establishment of the hospital, the surgical workload and handover to the local health system upon the end of deployment.

Are there differences between Maori and non-Maori patients undergoing primary total hip and knee arthroplasty surgery in New Zealand? A registry-based cohort study.

Aim: It has been well demonstrated that Maori have the poorest health status of any ethnic group in New Zealand. The aim of this study was to determine whether there are any differences between Maori and non-Maori patients in the severity of their arthritis preoperatively and in their postoperative functional outcomes following primary total hip and knee arthroplasty surgery. Secondary objectives were to compare general and mental health scores and to determine whether the intervention rate for Maori arthroplasty patients is appropriate.

Femoral neck fractures after arthroscopic femoral neck osteochondroplasty for femoroacetabular impingement.

Purpose: The objective of this study was to evaluate the rate, associated risk factors and outcome of insufficiency femoral neck fractures following arthroscopic femoral neck osteochondroplasty for femoroacetabular impingement.

Methods: Between 2005 and 2009, a consecutive series of 376 arthroscopic femoral osteochondroplasties for femoroacetabular impingement were performed and analysed. Seven postoperative fractures were found and comprise the fracture group.

Surgical hip dislocation versus hip arthroscopy for femoroacetabular impingement: clinical and morphological short-term results.

Introduction: Surgical hip dislocation (SHD) is an accepted standard to treat femoroacetabular impingement (FAI). However, arthroscopic techniques have gained widespread popularity and comparable results are reported. The purpose of this prospective comparative study was to test the hypothesis that, when compared to SHD, hip arthroscopy (HA) results in faster recovery, better short-term outcome, and equivalent morphological corrections.

Does previous hip arthroscopy negatively influence the short term clinical result of total hip replacement?

Introduction: The risk that hip preserving surgery may negatively influence the performance and outcome of subsequent total hip replacement (THR) remains a concern. The aim of this study was to identify any negative impact of previous hip arthroscopy on THR.

Methods: Out of 1271 consecutive patients who underwent primary THR between 2005 and 2009, 18 had previously undergone ipsilateral hip arthroscopy.

The reliability of computed tomography scanograms in the measurement of limb length discrepancy.

This study determined the intrarater and interrater reliabilities of measurements of paediatric limb length discrepancy on anteroposterior scout computed tomography scanograms. Seven physicians measured 26 films at two measuring sessions, separated by at least 8 weeks. High intraclass correlation coefficients above 0.
