Prevalence, Characteristics, and Associated Risk Factors of Wrist Fractures in Americans Above 50: The Cross-Sectional NHANES Study.

Summary: By analyzing data from NHANES, we aimed to evaluate the prevalence, characteristics, and associated factors of wrist fractures in Americans aged 50 and above.

Introduction: Wrist fractures, whose prevalence increases with age, are one of the most common fractures in the United States. However, epidemiological studies on the prevalence of wrist fractures of certain ages were limited.

Changes in alkaline phosphatase, calcium, C-reactive protein, D-dimer, phosphorus and hemoglobin in elderly osteoporotic hip fracture patients.

Background: This study aims to evaluate the association between serum alkaline phosphatase (ALP), calcium (Ca) and phosphorus (P), C-reactive protein (CRP) and D-dimer (D-D), and hemoglobin (Hb) in postoperative and preoperative osteoporotic hip fracture elderly patients.

Methods: A total of 32 operation patients with osteoporotic hip fracture over the age of 65 years old were admitted to the orthopedic unit and prospectively evaluated. All patients were treated according to specific protocols, according to the type of fracture.

CT Analysis of a Potential Safe Zone for Placing External Fixator Pins in the Humerus.

Iatrogenic radial nerve injures are a common complication during the placement of external fixator pins at the lateral aspect of the humeral shaft. This study uses a three-dimensional measurement technique to locate a safe entry point for humeral pins when externally fixating the elbow. We fixed a guide wire to the radial nerve by a suture string, and used computed tomography (CT) to scan the upper limbs of cadaver specimens.

Morphology of the lumbar multifidus muscle in lumbar disc herniation at different durations and at different ages.

The aim of the present study was to evaluate the relative functional volume of bilateral lumbar multifidus (LM) muscles across different stages and ages of patients with lumbar disc herniation (LDH). The relative functional volumes of LM muscles in both non-affected and affected sides in the L4-L5 and L5-S1 segmental level were measured in a resting prone position, and visual analogue score (VAS) for pain and Japanese Orthopedic Association (JOA) scores were recorded. The correlation between changes in the relative net volume of LM muscles and times of onset, ages, VAS and JOA scores were analyzed.
