This study aimed to investigate how long it takes for the dorsally displaced distal radial epiphysis to achieve realignment. We retrospectively reviewed 56 patients with dorsally displaced Salter-Harris type II distal radial epiphyseal fractures who were aged ≤15 years at the time of injury. All fractures were treated with closed reduction and immobilised using a sugar tong splint for 6 weeks. Read More

We report the case of a 62-year-old female patient with a triple-crush radial nerve injury, diagnosed in subsequent order following a fracture of the left humerus. The patient developed flaccid paralysis of all muscles innervated by the left radial nerve except the triceps brachii and reported a sensory deficit corresponding to the innervation territories of the posterior nerve of the forearm as well as the superficial branch of the radial nerve. Following neurolysis of the radial nerve at the humerus level, wrist extension as well as sensory perception on the dorsal aspect of the forearm recovered, but finger extension and thumb abduction were still impossible.

: The number of geriatric patients presenting with fragility fractures of the pelvis is increasing due to ageing Western societies. There are nonoperative and several operative treatment approaches. Many of which cause prolonged hospitalisation, so patients become bedridden and lose mobility and independence. Read More

: Three-dimensional planning and guided osteotomy utilizing patient-specific instrumentation (PSI) with the contralateral side used as a reference have been proven as effective in the treatment of malunions following complex fractures of the distal radius. However, this approach has not yet been described in relation to fracture reduction of the distal radius. The aim of this study was to assess the technical and logistical feasibility of computer-assisted surgery in a clinical setting using PSI for fracture reduction and fixation. Read More

Silicon nitride possesses a variety of excellent properties that can be specifically designed and manufactured for different medical applications. On the one hand, silicon nitride is known to have good mechanical properties, such as high strength and fracture toughness. On the other hand, the uniqueness of the osteogenic/antibacterial dualism of silicon nitride makes it a favorable bioceramic for implants. Read More

This review summarizes the current literature available on joint cartilage alterations in long-duration spaceflight. Evidence from spaceflight participants is currently limited to serum biomarker data in only a few astronauts. Findings from analogue model research, such as bed rest studies, as well as data from animal and cell research in real microgravity indicate that unloading and radiation exposure are associated with joint degeneration in terms of cartilage thinning and changes in cartilage composition.

In the last years, intramedullary compression screw (IMHCS) for instable transverse or short oblique proximal P1 fractures have been described. Although both anterograde (intraarticular or transarticular) and retrograde IMHCS techniques have shown good results, no comparison between anterograde and retrograde screw in P1 fractures has been published.

Purpose: We aimed to suggest treatment strategies for Seymour fractures (SFs) with varying clinical manifestations, based on the retrospective outcomes of patients seen at our institute.

Methods: Between March 2000 and December 2019, a total of 26 SF patients were categorized into 3 groups: acute typical SF (category 1; open fracture/exposed germinal matrix and physis), acute injuries but delayed presentation (category 2; presented to our institute more than 24 hours after the injury with misdiagnosis as simple nail injuries), and direct crush injuries (category 3; the most severe injury type, characterized by nail loss, nail bed lacerations, or maceration of the germinal matrix). In category 1, reduction was maintained using K-wire fixation without nail plate sutures. Read More
