Combined Naviculocuneiform and Calcaneocuboid Dislocation After Low-Energy Blunt Trauma: A Case Report.
Cureus
December 2024
Orthopaedic Surgery, Corewell Health William Beaumont University Hospital, Royal Oak, USA.
We present a case of a unique midfoot injury pattern including dislocations of the calcaneocuboid and naviculocuneiform joints with associated calcaneus and navicular fractures after low-energy injury. This combination of injuries is rare, especially with a low-energy mechanism. There are no current treatment guidelines.

Methods: Between January 2018 and January 2023, 119 patients with Colles fractures were retrospectively analyzed, including 39 males and 80 females, aged from 48 to 74 years old with an average of(60.58±6.
Cervical spine fracture dislocation with mild neurological deficits.
BMJ Case Rep
January 2025
Neurosurgery, Fu Jen Catholic University Hospital, New Taipei City, Taiwan
Cervical fracture dislocation often leads to neurological deficits, manifesting with sensory and motor symptoms, which may persist even after surgical intervention. We presented two cases with mild neurological deficits following such injuries. In Case 1, the patient presented with left-hand numbness 1 month after a car accident.

Objective: To investigate the effectiveness of modified single patellar tunnel medial patella femoral ligament (MPFL) reconstruction in the treatment of recurrent patellar dislocation.
Methods: Between January 2023 and June 2023, a total of 61 patients with recurrent patellar dislocation who underwent MPFL reconstruction with autologous semitendinosus were enrolled and divided into 2 groups using random number table method. In the patellar anchor group, 31 patients were treated with MPFL reconstruction with double medial patellar anchors, and 30 patients in the patellar tunnel group were treated with MPFL reconstruction with single patellar tunnel.
Buffer-Less Gallium Nitride High Electron Mobility Heterostructures on Silicon.
Adv Mater
January 2025
Department of Materials Science and Metallurgy, University of Cambridge, Cambridge, CB3 0FS, UK.
Thick metamorphic buffers are considered indispensable for III-V semiconductor heteroepitaxy on large lattice and thermal-expansion mismatched silicon substrates. However, III-nitride buffers in conventional GaN-on-Si high electron mobility transistors (HEMT) impose a substantial thermal resistance, deteriorating device efficiency and lifetime by throttling heat extraction. To circumvent this, a systematic methodology for the direct growth of GaN after the AlN nucleation layer on six-inch silicon substrates is demonstrated using metal-organic vapor phase epitaxy (MOVPE).
