Chronic pectoral pain following medial pectoral nerve injury: A case report

Ultrasound-Guided Lateral Pectoral Nerve Pulsed Radiofrequency in a Patient With Refractory Pectoral Pain: A Case Report of a Novel Approach

“…Some articles report that physiotherapy including an exercise program and changes in work activities may help to prevent further damage [ 2 , 7 ]. In our report, our patient did a cycle of physiotherapy that didn’t help in her intense pain.…”

“…The lateral pectoral nerve (LPN) is commonly injured along with the brachial plexus, but its isolated lesions are scarce. There are only a few reports in the literature regarding isolated LPN injury, related to sports, compression by the use of seat belts or repeated contractions of the pectoralis muscle related to training regimens, or iatrogenic to surgical procedures such as breast augmentation surgery [1][2][3].…”

“…Clinical findings of lateral pectoral nerve injury may include asymmetry of the chest wall associated with atrophy and weakness of the entire pectoralis major muscle or parts of it, and sometimes there is also pain associated. This might be explained by the fact that although this nerve mostly carries motor fiber, it is also considered to carry proprioceptive and nociceptive fibers, responsible for a part of the anterior glenohumeral joint complex innervation [ 2 - 3 ]. Plus, a partially denervated muscle or, after a while, an atrophic and weak pectoralis major muscle, when solicited, may conduct to spasms, which are described as producing intense pain.…”
