The anatomy of the fibrous and osseous components of the first extensor compartment of the wrist: a cadaveric study

De Quervain disease is the stenosing tenosynovitis of the first extensor compartment of the wrist. It is diagnosed with a history of pain at the radial aspect of the wrist and a positive Finkelstein test. Although anatomic variations, such as a septum within the compartment, are considered as risk factors, bony anatomy of distal radius and its correlation with the septa are studied scarcely in the literature

Sciatic nerve localization relative to the position of the hip, an anatomical study.

The incidence of iatrogenic peripheral nerve injury during hip arthroplasty procedures has been reported to be between 0.6 and 1.3 percent. The relative risk of nerve palsy is higher in certain groups of patients such as women, patients with developmental dysplasia of the hip, and those who have undergone revision arthroplasty. In this study, the dynamic relationship between the acetabulum and the sciatic nerve, which is important for preventing sciatic nerve palsy during the hip surgery, was investigated. The sciatic nerve was exposed in 69 cadaveric hips. The relationship between the bony acetabulum and the sciatic nerve was examined in three different positions; as the ipsilateral hip was flexed; extended; or in neutral position. We found that the middle part of the posterior acetabular rim was closer to the sciatic nerve than its superior or inferior parts. The sciatic nerve was perilous when the ipsilateral hip was flexed and the middle part of the posterior acetabular rim was more risky than the superior or inferior parts, in terms of iatrogenic sciatic nerve injury

Sex differences in the radial grooves in the first extensor compartment

De Quervain tenosynovitis affects the first extensor compartment of the wrist and occurs more frequently in females. This high prevalence could not be explained by soft tissue. As the osseous anatomy has been mostly neglected, we aimed to compare the distal radius between the sexes

Foramen of Vesalius

Objectives: To investigate the frequency of unilateral or bilateral foramen of Vesalius (FV), number of FV present on one side, and presence of a septum on FV
