The extensor indicis proprius muscle (EIPM) is considered a key muscle in the assessment of the level of the neurologic lesion causing any motor or sensory medio-cubital impairment of the hand. The aim of this study is to illustrate the anatomical peculiarities of the EIPM, the ultrasound (US) anatomy of the inferoposterior part of the forearm, and the technique of US-guided electromyography (EMG) of the EIPM. The US-guided EMG of the EIPM is technically easy and safe for young practitioners, provided there is a good knowledge of US anatomy of the inferoposterior part of the forearm.

Purpose Of The Study: The aim of this study to evaluate the subjective and objective results of Extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfer with an emphasis on donor site morbidity.
Material And Methods: 17 patients (59% men, 41% women) who underwent EIP-EPL transfer were retrospectively analyzed. The mean age was 43 (9-64) years, and the mean follow-up was 72 (19-124) months.
Inflammatory and degenerative changes in the extensor pollicis longus muscle and tendon following ruptures caused by distal radius fractures.

Background: Rupture of extensor pollicis longus tendon (EPL) is a known complication following a distal radius fracture (DRF). Although the precise mechanisms behind these ruptures remain unclear, vascular impairment is thought to play a significant role. Additionally, the impact of an EPL rupture on microstructure of the tendon and muscle is not well understood, but such information could be important in guiding treatment strategies.

Clasped thumb is characterised by thumb adduction and flexion deformity at the metacarpophalangeal joint caused by abnormalities in the extensor tendons. While conservative treatments are effective in infants, surgical intervention is necessary for older who experience deformities or functional impairments. We report an adolescent patient with an untreated clasped thumb who underwent extensor pollicis brevis (EPB) reconstruction using the extensor indicis proprius (EIP) tendon through the first dorsal compartment.

Purpose: The current meta-analysis aimed to investigate the extensor digitorum brevis manus (EDBM) muscle variability by calculating the pooled prevalence of all published variants. After considering the pooled prevalence, these variants were classified based on their insertion and relationship with the extensor indicis (EI) muscle and/or tendon. The origin of the variants, neural and arterial supply, and the terminology of the EDBM variants were further investigated.

Spontaneous rupture of the extensor pollicis longus (EPL) tendon has been reported to be uncommon. Several possible causes and precipitating factors have been reported for this rupture, including prior surgery to the distal radius. We report the case of an 18-year-old male professional athlete who presented with an inability to extend their left thumb.
