Peripheral arterial pseudoaneurysm is an uncommon complication after open reduction and internal fixation of bone fractures. Here, we describe a rare case of a 72-year-old man who developed a delayed pseudoaneurysm of the anterior interosseous artery after open reduction and internal fixation of an isolated ulnar fracture (nightstick fracture). He presented with a painful forearm mass and anterior interosseous nerve (AIN) neuropathy. Though rare, the appearance of AIN neuropathy is a potential complication of forearm fractures' fixation that should be diagnosed early and managed with a prompt and appropriate treatment.

Introduction: During 280 years of studies of the anatomy of the distal tibiofibular articulation, there have arisen many unclear issues regarding the description of individual structures and their terminology. These historical inaccuracies were subsequently reflected in the clinical practice.

Materials And Methods: A literature search of original publications and historical sources was performed.

Objectives: Proximal median nerve (PMN) neuropathies are caused by lesions proximal to the carpal tunnel, which include the forearm, elbow, upper arm, and brachial plexus. Differentiating between carpal tunnel syndrome and PMN neuropathies is important to guide management and is based on clinical, electrodiagnostic (EDX), and ultrasound (US) findings. This study describes the clinical, EDX, and US features in 62 patients with PMNs.

The human upper limb has undergone various evolutionary myologic changes, accompanied by corresponding modifications in the anatomical course of neurovascular structures. In this study, we aimed to elucidate the emergence of the accessory head of the flexor pollicis longus (AHFPL) muscle as a beneficial biomechanical evolutionary development and its topographical relationship with adjacent neurovascular structures. In this pursuit to understand this phenomenon, dissections were conducted on sixty-two upper limbs from thirty-one cadavers.

Background: Wrist osteoarthritis poses significant challenges in pain management and functional impairment. Current surgical interventions often sacrifice wrist motion and entail long recovery times. Minimally invasive denervation offers a promising alternative by targeting sensory nerves.

Article Synopsis
  • - Supracondylar fractures of the humerus are the most common elbow fractures in children and can lead to neurovascular complications, including rare cases of isolated radial nerve palsy.
  • - A case of a six-year-old boy with a displaced supracondylar fracture showed symptoms of radial nerve palsy, such as wrist drop, after falling from a playground, confirmed by imaging as a Gartland Type III fracture.
  • - After treatment involving closed reduction and percutaneous pinning, the child's radial nerve function progressively improved, leading to full recovery and fracture healing by the 12-week follow-up, highlighting the need for timely management of such injuries.
