In cases of anterior interosseous nerve (AIN) syndrome, it is often difficult to differentiate between compression neuropathy and neuritis.
This review analyses the clinical aspects of the neuritic AIN syndrome and the different diagnostic tools for securing the diagnosis and differentiating the condition from compression neuropathy. Based on these data, the current therapeutic options are proposed.
The AIN syndrome often results from neuritis of the AIN fascicles within the trunk of the median nerve. The differentiation between neuritis and compression neuropathy of the AIN is based on dedicated neurophysiological examinations as well as nerve sonography and MRI neurography. Although conservative treatment is the gold standard, microsurgical interventions have become more important in recent years.
A dedicated diagnostic workup of the AIN syndrome is paramount for optimal treatment. Conservative treatment remains the standard to date. However, if torsions and constrictions of nerve fascicles are detected, intrafascicular neurolysis should be considered, as current research shows the potential for an improved outcome in such cases.
在前臂骨间神经（AIN）综合征病例中，区分压迫性神经病变和神经炎往往很困难。
本综述分析了神经炎型AIN综合征的临床情况以及用于确诊并将该病症与压迫性神经病变相鉴别的不同诊断工具。基于这些数据，提出了当前的治疗选择。
AIN综合征通常由正中神经干内AIN束的神经炎引起。AIN神经炎与压迫性神经病变的鉴别基于专门的神经生理学检查以及神经超声和磁共振神经成像。尽管保守治疗是金标准，但近年来显微外科干预变得更为重要。
对AIN综合征进行专门的诊断检查对于优化治疗至关重要。保守治疗至今仍是标准治疗方法。然而，如果检测到神经束的扭转和狭窄，应考虑进行束内神经松解，因为目前的研究表明在这种情况下有可能改善预后。
