Upper-limb rehabilitation exoskeletons offer a valuable solution to support and enhance the rehabilitation path of neural-injured patients. Such devices are usually equipped with a network of sensors that can be exploited to evaluate and monitor the performances of the users. In this work, we assess the normality ranges of different motor-performance indicators on a group of 15 healthy participants, computed with the benchmark toolbox of AGREE, an upper limb motorized exoskeleton. The toolbox implements a benchmarking scheme for the evaluation of the upper limb, used to test anterior reaching at rest position height and hand-to-mouth motor skills. We selected kinematic and electromyography performance indicators to assess the different motor abilities. We performed a pilot evaluation on three neurological patients, to verify if the AGREE benchmark toolbox was able to distinguish patients from healthy subjects on the basis of the selected performance indicators. Through a comparison between results obtained by the healthy and the small group of motor-impaired users, we successfully calculated the normality ranges for the selected performance indicators, and we pilot-showed how data gathered from AGREE can be used to evaluate the current status of the patients.

Fracture-related infection (FRI) is a serious orthopaedic complication and its diagnosis, particularly in the upper extremity, is difficult and poorly defined in current literature. An international consensus definition of FRI was published in 2018, and our scoping review aims to investigate FRI diagnostic tools reported in the primary literature and their biostatistical utility. A review of articles generated from the PubMed/NCBI search term "fracture-related infection" was undertaken using PRISMA methodology.

Atypical mycobacteria can cause rare and atypical infections of the hand. We report the case of an immunocompetent 46-year-old male initially presenting with thumb felon and progressively developing symptoms of carpal tunnel syndrome, tenosynovitis of multiple fingers and a sporotrichoid lymphocutaneous infection causing chronic cutaneous lesions all over the body. We would like to highlight the diagnostic and therapeutic difficulties of these atypical infections, which mimic other conditions and can cause a lot of morbidity.

Atypical lipomatous tumors/well-differentiated liposarcomas (ALT/WDLPS) are low-grade, slow-growing, and locally aggressive tumors. We investigated clinical outcomes and recurrence factors for ALT/WDLPS of the extremities. This is retrospective study across three institutions which included patients who underwent surgery for ALT/WDLPS from 2001 to 2019.

Masquelet's induced membrane technique in the upper limb: a systematic review of the current outcomes.

J Orthop Traumatol

January 2025

Unità Operativa di Ortopedia e Traumatologia, APSS Trento, Largo Medaglie d'oro, 9, 38121, Trento, Italy.

Background: The Masquelet induced membrane technique is a surgical procedure that allows the reconstruction of segmental bone defects using a relatively simple approach that requires minimal resources from both the healthcare facility and the patient. Historically applied to the lower limb, this technique is gaining increasing attention in the literature for its use in the upper limb.

Methods: A systematic review of the literature was conducted using the PubMed and Google Scholar databases to identify all studies reporting the outcomes of the Masquelet induced membrane technique in the long bones of the upper limb (humerus, radius, and ulna) with a sample size of at least 3 patients.

Upper limb lymphedema is the most common complication after breast cancer therapy. Suddenly disturbed lymphatic transport in the affected arm causes tissue fluid accumulation in tissue spaces, limb enlargement, and secondary changes in tissue. Early compression therapy is necessary.
