Comparing the Palmar Radiocarpal Artery Vascularized Bone Graft with Alternatives for Unstable Scaphoid Nonunions: A Retrospective Analysis.

Purpose: We compared the radiographic union and magnitude of humpback deformity correction when using different vascularized bone grafts (VBGs) and nonvascularized bone grafts (NVBGs) in the treatment of unstable scaphoid nonunions (USNUs).

Methods: This was a retrospective radiographic review of 93 patients with an USNU treated between 2013 and 2022 at a single center by a single surgeon. Inclusion criteria included skeletally mature patients with radiographic evidence of an USNU resulting from failure of either nonsurgical or operative treatment.

External evaluation of intravenous vancomycin population pharmacokinetic models in adults receiving high-flux intermittent haemodialysis.

Aims: Patients undergoing haemodialysis (HD) are at greater risk of methicillin-resistant Staphylococcus aureus infections requiring intravenous vancomycin. Close vancomycin therapeutic drug monitoring is warranted in HD patients as renal clearance is the primary elimination pathway. Clinically, population pharmacokinetics (popPK) model-informed dosing is commonly used.

Mid to long-term survivorship of hip arthroplasty in patients 40 years and younger.

Background: Etiology of hip osteoarthritis (OA) and survival of hip arthroplasty in the young (below 40-years-old) remains poorly described. Furthermore, joint survivorship mid to long-term and PROMs according to the etiology are unclear. The study aims were to 1) identify the indications for arthroplasty in the below 40-years-old cohort; 2) define hip arthroplasty outcomes in the young and 3) test whether patients with sequelae of pediatrics hip disease have inferior outcome compared to other patients.

The relationship of pain catastrophizing with postoperative patient-reported outcome measures in adults with pre-arthritic hip disease.

The association between preoperative pain catastrophizing and postoperative patient-reported outcome measures of patients with pre-arthritic hip disease was evaluated. All patients scheduled for joint-preserving surgeries of the hip (JPSH) at our institution were approached. Patient demographics (age, sex, body mass index (BMI)), pain intensity (Numeric Pain Scale (NPS)) and pain catastrophizing (Pain Catastrophizing Scale (PCS)) were collected preoperatively.

Feline lung-digit syndrome: A differential diagnosis for shifting, waxing and waning lameness in a cat.

The clinical presentation, cytologic findings, radiographic findings, and postmortem assessment of a cat with primary pulmonary adenocarcinoma with multiple digital metastasis are described. An unusual shifting, waxing and waning pattern of lameness, suspected to be an early manifestation of digital metastasis before any gross lesions were visible, was documented. Initial cytologic finding of a lung nodule was equivocal for diagnosis of neoplasia despite being strongly suspicious.
