[Postoperative Pain Level Following Surgery of the Hand and Wrist in the Ambulatory Setting].

Background: Surgical procedures of the hand are increasingly performed in an ambulatory setting. Postoperative analgesia is based empirically on the painfulness of individual surgical procedures without these having been examined systematically.

Patients And Methods: The painfulness (visual analogue scale) of 722 surgical procedures of the hand and wrist (1 July 2021 to 30 June 2023) was assessed until day 5.

[Peripheral nerve grafting].

Objective: Peripheral nerve lesions often lead to significant and permanent loss of motor and sensory function. The aim of peripheral nerve grafting is to bridge nerve defects.

Indications: When tension-free nerve repair is not possible, peripheral nerve grafting is indicated.

Bilateral ST-coalition with thumb hypoplasia and scaphoid synchondrosis.

Carpal coalitions are rare wrist anomalies and are most often diagnosed incidentally. Due to their infrequent occurrence, there is a lack of treatment guidelines in the literature. We present a case study of a 13-year-old boy who presented with symptomatic synchondrosis in both scaphoids along with a bilateral osseous coalition between the scaphoid and trapezium bones in combination with bilateral thumb hypoplasia.

Tumoral Calcinosis at a Finger Metacarpophalangeal Joint.

A 51-year-old patient presented with a painful swelling palmar to the metacarpophalangeal joint of the ring finger. A round tumor was detected using X-rays and MRI. After excision, tumoral calcinosis could be verified histologically.

Direct high-pressure Injury of the Palm after Injection of a Capsaicin-filled Gas Pistol.

High injection lesions of the hand are among the most serious injuries, with concomitant consequences. These lesions are often underestimated and may entail additional damages if that is the case. Not only the physical impact but also the chemical nature of the substance dictate the treatment.

[Arthroplasty of the hand and wrist].

Arthrosis and autoimmune arthritis frequently lead to major impairment of hand function. Primary therapy consists of well- tried conservative treatments and joint preserving surgical options for special indications. In advanced stages silicon spacers remain the gold standard surgical option for replacement of proximal interphalangeal and metacarpophalgeal joints of the fingers.

[Radiocarpal dislocations and fracture dislocations].

Radiocarpal dislocations and fracture dislocations are rare but always severe and complex injuries. They occur frequently in young and active patients as a result of high energy accidents. A detailed clinical and imaging examination and an accurate classification leads to a suitable and mostly surgical treatment strategy.

The Reliability of Preoperative Total Knee Arthroplasty Planning -a Comparison of Two Calibration Markers.

Background: Preoperative templating is the gold standard in planning elective total knee arthroplasty. This retrospective study analyses preoperative templating by using two different calibration devices.

Methods: Preoperative radiographic templating with TraumaCad using two different calibration devices was performed in 231 patients.

Ultrafast transient absorption and solvation of a super-photoacid in acetoneous environments.

The phenomenon of photoacidity, i.e., an increase in acidity by several orders of magnitude upon electronic excitation, is frequently encountered in aromatic alcohols capable of transferring a proton to a suitable acceptor.

Long-term preservation of metacarpophalangeal joint function in traumatic defects by metatarsophalangeal osteochondral transplantation.

Introduction: The integrity of the metacarpophalangeal (MCP) joints is essential for finger and hand function. Preservation of range-of-motion is one of the aims in reconstruction of complex injuries to these joints. Osteochondral transplants have shown to be reliable in reconstruction of various joint defects.

SCAI Guidelines for the Management of Patent Foramen Ovale.

Background: Patent foramen ovale (PFO) is a vestigial congenital cardiovascular structure present in around 25% of adults. In most cases, PFO is entirely benign and requires no treatment. However, it may cause serious complications under certain circumstances.

[Arthroscopic reconstruction of scaphoid nonunions].

Objective: Minimally invasive arthroscopically assisted reconstruction of scaphoid nonunions.

Indications: Delayed union or nonunion of the scaphoid with sclerosis and with indication for bone transplantation. Limited arthritic changes at the radial styloid.

[Resection arthroplasty for thumb basal joint arthritis].

Due to the crucial role of the thumb for gripping, osteoarthritis of the first carpometacarpal joint leads to a substantial impairment of hand function. There are effective nonoperative and joint-preserving surgical treatment options for early stages of the disease. In advanced cases, after exploiting conservative treatment, carpometacarpal thumb arthrodesis or arthroplasty may be indicated in selected cases but trapeziectomy with or without interposition or suspension constitutes the gold standard surgical procedure.

Effect of different forearm positions on fragment rotation in extra-articular distal radius fractures: A cadaveric study.

Objective: The aim of the study was to investigate the effect of different arm positions (hand pronation/supination and elbow flexion/extension) on fragment rotation in extra-articular distal radius fractures in a cadaveric model.

Methods: In this study, ten fresh-frozen cadaveric upper extremities from five donors with a mean age of 69 ± 12 years were used. Two cortical pins were inserted in the radius and the ulna.

Real-World Experience With the SAPIEN 3 Ultra Transcatheter Heart Valve: A Propensity-Matched Analysis From the United States.

Short-term radiological results after spheroid-based autologous chondrocyte implantation in the knee are independent of defect localisation.

Background: Lesions of articular cartilage represent a crucial risk factor for the early development of osteoarthritis. Autologous chondrocyte implantation (ACI) is a well-established procedure in therapy of those lesions in the knee. The aim of the presented study is to detect differences in short-term radiological outcome depending on defect localization (femoral condyle vs.

Fluorescence detected circular dichroism (FDCD) for supramolecular host-guest complexes.

Fluorescence-detected circular dichroism (FDCD) spectroscopy is applied for the first time to supramolecular host-guest and host-protein systems and compared to the more known electronic circular dichroism (ECD). We find that FDCD can be an excellent choice for common supramolecular applications, for the detection and chirality sensing of chiral organic analytes, as well as for reaction monitoring. Our comprehensive investigations demonstrate that FDCD can be conducted in favorable circumstances at much lower concentrations than ECD measurements, even in chromophoric and auto-emissive biofluids such as blood serum, overcoming the sensitivity limitation of absorbance-based chiroptical spectroscopy.

Long-term results of more than 13 years after arthroscopic repair of triangular fibrocartilage complex (TFCC) Palmer 1B tears: a comparison with short- and mid-term results.

Purpose: Goal of this study was the assessment of long-term outcome of arthroscopically assisted repair of Palmer 1B/Atzei 1 triangular fibrocartilage complex tears and the comparison with short- and mid-term results.

Methods: The study included nineteen patients (mean 49.2 years of age) with a mean follow-up time of 13.

[Paronychia and Felons - Surgical Treatment].

Infections of the distal phalanx are the most common of all hand infections. There are dorsal localised infections, which develop in the area of the nail and are called paronychia, and palmar infections, which affect the fingertip and are the typical felons. The acute paronychia must be specifically opened depending on the site of infection.
