Objective: This study aimed to clarify the morphology of the Martin-Gruber anastomosis (MGA) in Chinese.
Methods: One hundred and five Chinese upper limbs (36 males and 20 femalese) were dissected to find the connections between medial nerve and ulnar nerve. The MGA was classified as previously described by Lee.
Results: MGA was found in 24 cases (22.9%), in 11 of the 36 male and 5 of the 20 female. There was no obvious difference in the frequency of MGA in both upper limbs. Most MGA ulnar position was located at the medial and distal segment of the forearm.
Conclusion: MGA anatomy could play important role in forensic diagnosis of ulnar nerve injury in Chinese population.

Body composition is a determining factor in the physical performance of cyclists, directly influencing efficiency and power during competitions. Understanding these aspects can help optimize training and maximize results. This study aimed to analyze the influence of body composition on physical performance in mountain bike athletes.

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.

December 2024
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.

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.
