Nerve injury associated with shoulder surgery

Introduction Progress in shoulder surgery is associated with improved operating rooms equipment, advanced surgical products and minimally invasive techniques. There are rare injuries to nerves and vessels being intersected or pulled into the sutures. However, marginal tears, compression and nerve entrapment of trunks during access retraction, catheterization, inadequate correct of the patient on the operating table and errors in rehabilitation can be common. The purpose was to identify factors predisposing to peripheral nerve injury to the upper limb during shoulder surgery and offer prevention options. Material and methods Major studies in the field of shoulder anatomy and surgery published between 1984 and 2023 were reviewed to identify anatomical, biomechanical and perioperative factors leading to peripheral nerve injuries. The original literature search was conducted on key resources including GoogleScholar, PubMed, ScienceDirect, RSCI, Scopus. Four approaches were used for structuring and informative presentation of the data to include types of the peripheral nerve injury in the upper limb. Results and discussion Factors predisposing to the peripheral nerve injury in the upper limb during shoulder surgery were identified in the review. Prevention measures include the patient positioned on the operating table with adequate fixation of the head and torso, regardless of the chosen position; traction of the involved upper limb with a load of not greater than 9 kg using a specialized clamp; preoperative marks of the surgical field and staining of bone landmarks; the arthroscopic ports 1–2 cm to be shifted more distally minimizing the fluid flow into the joint during a long operation. Postoperative consultation with rehabilitation specialists is essential to develop an early activation program and assess the risks of neurological disorders. Conclusion The shoulder anatomy and the localization of unsafe zones of the shoulder, the risks associated with a particular manipulation were explored for effective preoperative planning and prevention of neurological complications in the treatment of surgical pathology of the shoulder joint.
