Comparison of optical coherence tomography and high frequency ultrasound imaging in mice for the assessment of skin morphology and intradermal volumes.

Optical coherence tomography (OCT) and high-frequency ultrasound (HFUS), two established imaging modalities in the field of dermatology, were evaluated and compared regarding their applicability for visualization of skin tissue morphology and quantification of murine intradermal structures. The accuracy and reproducibility of both methods were assessed ex vivo and in vivo using a standardized model for intradermal volumes based on injected soft tissue fillers. OCT revealed greater detail in skin morphology, allowing for detection of single layers due to the superior resolution.

A rare combination of brachymetatarsia and congenital hallux varus: case report and review of the literature.

Hallux varus is defined as a medial deviation of the phalanx at the first metatarsophalangeal joint and can be congenital or acquired. Brachymetatarsia is defined as shortening of the metatarsal bones. A combination of hallux varus and brachymetatarsia is rare.

Biomechanical testing of a new knotless suture anchor compared with established anchors for rotator cuff repair.

Various suture anchors are available for rotator cuff repair. For arthroscopic application, a knotless anchor was developed to simplify the intra-operative handling. We compared the new knotless anchor (BIOKNOTLESStrade mark RC; DePuy Mitek, Raynham, MA) with established absorbable and titanium suture anchors (UltraSorbtrade mark and Super Revo 5mmtrade mark; ConMed Linvatec, Utica, NY).
