Does the use of tibial stem extensions reduce the risk of aseptic loosening in obese patients undergoing primary total knee arthroplasty: A systematic review and meta-analysis.

Background: This study aimed to compare the risk of revision for aseptic loosening in obese (body mass index >30 kg/m) patients with stemmed (ST) versus non-stemmed (NST) tibial implants in primary total knee arthroplasty (TKA).

Methods: A systematic review and meta-analysis were conducted following PRISMA and MOOSE guidelines. Studies reporting a direct comparison between ST and NST tibial implants in obese patients were included.

Assessment of Shoulder Range of Motion Using a Wireless Inertial Motion Capture Device-A Validation Study.

(1) Background: Measuring joint range of motion has traditionally occurred with a universal goniometer or expensive laboratory based kinematic analysis systems. Technological advances in wearable inertial measurement units (IMU) enables limb motion to be measured with a small portable electronic device. This paper aims to validate an IMU, the 'Biokin', for measuring shoulder range of motion in healthy adults; (2) Methods: Thirty participants completed four shoulder movements (forward flexion, abduction, and internal and external rotation) on each shoulder.

Diagnostic accuracy of computed tomography-guided biopsy in pathological fractures.

Background: Obtaining a histological diagnosis is essential for appropriate management of pathological fractures. Computed tomography (CT) is an accurate method of obtaining diagnosis for musculoskeletal tumours. We analysed whether diagnostic accuracy was maintained in the evaluation of pathological fractures.

Analgesic effect of subanesthetic intravenous ketamine in refractory neuropathic pain: a case report.

A 59-year-old male patient with progressive neuropathic pain secondary to chronic idiopathic axonal polyneuropathy responded poorly to conventional therapies including gabapentin, tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors and opioids. Following continuous intravenous administration of low dose ketamine, an N-methyl-D-aspartic acid receptor antagonist, 20 mg/h for 5 days, almost complete pain relief was obtained without significant side effects. The analgesic effect lasted 10-12 weeks and the ketamine infusion was repeated, with this pattern being maintained for 3.
