More than a feeling?-Overruling the preoperatively templated offset option leads to a minor offset increase in short stem total hip arthroplasty.
Short stems are increasingly used in total hip arthroplasty (THA) because of advantages in bone and soft tissue preservation and reconstruction of hip geometry. Digital templating is essential in determining the correct offset option and stem size in THA. However, the preoperative template sizes might be intraoperatively overruled. ⋯ Intraoperative overruling of the preoperative digital template in cementless short stem total hip arthroplasty results in an increase of hip offset compared to a contralateral healthy hip. However, the increase is marginal and clearly under 5 mm compared to the contralateral healthy hip.

Elliptical heads result in increased glenohumeral translation along with micro-motion of the glenoid component during axial rotation in total shoulder arthroplasty.
Elliptical-shaped humeral head prostheses have recently been proposed to reflect a more anatomic shoulder replacement. However, its subsequent effect on micro-motion of the glenoid component is still not understood. ⋯ Controlled Laboratory Study.

Clinicians' perceptions around discectomy surgery for lumbar disc herniation: a survey of orthopaedic and neuro-surgeons in Australia and New Zealand.
Understanding practice-based differences in treatment of lumbar disc herniations (LDHs) is vital for reducing unwarranted variation in the delivery of spine surgical health care. Identifying factors that influence surgeons' decision-making will offer useful insights for developing the most cost-effective and safest surgical strategy as well as developing surgeon education materials for common lumbar pathologies. This study was to capture any variation in techniques used by surgeons in Australia and New Zealand (ANZ) region, and perceived complications of different surgical procedures for primary and recurrent LDH (rLDH). ⋯ Surgeons' annual practice volume and practice setting have significant influences in the selection of surgical procedures and the perception of surgical complications when treating LDHs.

The 'critical trochanter angle' does not show superiority over the CCD angle in predicting varus stem alignment in cementless short-stem total hip arthroplasty.
Varus positioning of the femoral stem can affect the hip offset (HO). The critical trochanter angle (CTA) was introduced in 2019 as a novel geometric angle, to predict varus stem alignment in cementless straight stem THA. The aim of this study was to evaluate the applicability of the CTA as a predictor for stem alignment in THA with a cementless neck resecting short stem. ⋯ IV.

Clinical effects of direct anterior internal fixation with Herbert screws on hip joint function and quality of life in patients with Pipkin II femoral head fractures.
The study aimed to explore the therapeutic effects of direct anterior internal fixation with Herbert screws on hip joint function and quality of life in patients with Pipkin type II femoral head fractures (FHF). ⋯ The treatment of directly anterior internal fixation with Herbert screws is effective for Pipkin type II FHF, like improving the function of hip joint and quality of life in patients. The method is reliable and worth clinical use.
