J Clin Orthop Trauma 2020 May-Jun;11(3):348-356. Epub 2020 Apr 21.

Indian Spinal Injuries Centre, New Delhi, India.

Background: Numerous publications of the late 20th century have presented the radiological outcome of open technique for distal metatarsal osteotomy for mild to moderate hallux valgus and the clinical outcomes by means of well-established scoring systems which have been published and make these open techniques today's benchmark and gold standard. Minimally invasive procedures reduce surgical trauma because they are performed without large incisions, and injury to the soft tissues is limited. This has the theoretical advantages of improved recovery and decreased rehabilitation times. Read More

'Soccer toe': Chronic physeal injury of the great toe metatarsal in a skeletally immature child - A case report.

SA J Radiol 2020 22;24(1):1834. Epub 2020 Apr 22.

Department of Radiology, Harvard Medical School, Boston Children's Hospital, Boston, MA, United States of America.

Chronic physeal stress injuries in children can result from ongoing, repetitive compression, distraction and/or shear forces during sports-related activity, and manifest as physeal widening on imaging. We present an 11-year-old soccer athlete with focal physeal widening of her great toe metatarsal and postulate that ongoing or repetitive stress from soccer play may manifest as this imaging appearance. We suggest that recognition of this entity in growing children might explain pain, if present, and guide conservative treatment. Read More

A Part of the Medial Branch of the Deep Peroneal Nerve Distributes the Dorsal Pedis Artery and Its Distribution Area is Close to the Acupuncture Point LR3 (Taichong).

Evid Based Complement Alternat Med 2020 14;2020:6760958. Epub 2020 Apr 14.

Department of Anatomy, Division of Basic Medical Science, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa 259-1193, Japan.

Cutaneous nerves have vascular branches (VBs) that reach the arteries and are thought to be involved in arterial constriction. We aimed to examine the anatomical and histological relationship between the VBs of a cutaneous nerve in the foot and the acupuncture point LR3 (Taichong), which is a depression between the base of the first and second metatarsal bones on the dorsum of the foot and is a source point of the foot. We examined 40 cadaver feet to assess the distribution areas of the VBs of the medial branch of the deep peroneal nerve (MBDPN). Read More

Cone-beam imaging with tilted rotation axis: Method and performance evaluation.

Med Phys 2020 Apr 27. Epub 2020 Apr 27.

Department of Biomedical Engineering, Johns Hopkins University, Baltimore, MD, 21205, USA.

Purpose: The recently introduced robotic x-ray systems provide the flexibility to acquire cone-beam computed tomography (CBCT) data using customized, application-specific source-detector trajectories. We exploit this capability to mitigate the effects of x-ray scatter and noise in CBCT imaging of weight-bearing foot and cervical spine (C-spine) using scan orbits with a tilted rotation axis.

Methods: We used an advanced CBCT simulator implementing accurate models of x-ray scatter, primary attenuation, and noise to investigate the effects of the orbital tilt angle in upright foot and C-spine imaging. Read More

Incorporating subject-specific geometry to compare metatarsal stress during running with different foot strike patterns.

J Biomech 2020 May 9;105:109792. Epub 2020 Apr 9.

Sport and Health Sciences, University of Exeter, Exeter, UK.

Stress fracture of the second metatarsal is a common and problematic injury for runners. The choice of foot strike pattern is known to affect external kinetics and kinematics but its effect on internal loading of the metatarsals is not well understood. Subject-specific models of the second metatarsal can be used to investigate internal loading in a non-invasive manner. Read More
