“…However, the infraspinatus muscle exhibits wavy or curved contours, ligamentous discontinuities, variable signal intensity, contour elongation, and muscle irregularities within areas of atrophy. [19] Therefore, a single measurement may result in an incorrect measurement. IMCSA, which measures the total cross-sectional area of the infraspinatus muscle, was thought to be able to predict SNE syndrome through the cross-sectional area of the infraspinatus muscle, unlike IMT.…”

Suprascapular nerve entrapment (SNE) syndrome is a commonly overlooked cause of shoulder weakness and pain. It frequently causes weakness over the posterior and lateral and posterior aspects of the shoulder, as well as pain of infraspinatus muscles. Therefore, we considered that the infraspinatus muscle cross-sectional area (IMCSA) might be a new morphological parameter to analyze SNE syndrome. We assumed that the IMCSA is an important morphologic parameter in SNE syndrome diagnosis. We acquired infraspinatus muscle data from 10 patients with SNE syndrome and from 10 healthy subjects who had undergone magnetic resonance imaging of the shoulder and who revealed no evidence of SNE syndrome. We analyzed the infraspinatus muscle thickness (IMT) and IMCSA at the shoulder on the imaging of the shoulder using our image analysis program. The IMCSA was measured as the whole infraspinatus muscle cross-sectional area that was most atrophied in the sagittal S-MR images. The IMT was measured as the thickest level of infraspinatus muscle. The mean IMT was 29.17 ± 2.81 mm in the healthy subjects and 25.22 ± 3.19 mm in the SNE syndrome group. The mean IMCSA was 1321.95 ± 175.91 mm2 in the healthy group and 1048.38 ± 259.94 mm2 in the SNE syndrome group. SNE syndrome patients had significantly lower IMT (P < .001) and IMCSA (P < .001) than the healthy group. The ROC curve shows that the optimal cutoff point of the IMT was 26.74 mm, with 70.0% sensitivity, 70.0% specificity, and an AUC of 0.83 (95% CI, 0.65–1.00). The best cutoff value of the IMCSA was 1151.02 mm2, with 80.0% sensitivity, 80.0% specificity, and AUC of 0.87 (95% CI, 0.69–1.00). The IMT and IMCSA were both significantly associated with SNE syndrome. And the IMCSA was a highly sensitive diagnostic tool.

“…60 Minimally invasive interventions such as pulsed radiofrequency and peripheral nerve stimulation have been proposed as adjuvants for pain control, however, further research is needed to clarify their potential role in the management, especially in athletic populations. 75,76 In patients with overt muscle atrophy and/or space-occupying lesions, as well as those who fail to improve with an appropriate course of conservative care, operative decompression of the nerve is recommended. Superior surgical outcomes are associated with operative intervention within 6 months of initial symptom onset.…”

Peripheral nerve injuries in athletes affect the upper limb more commonly than the lower limb. Common mechanisms include compression, traction, laceration, and ischemia. Specific sports can have unique mechanisms of injury and are more likely to be associated with certain neuropathies. Familiarity with these sport‐specific variables and recognition of the common presentations of upper limb neuropathic syndromes are important in assessing an athlete with a suspected peripheral nerve injury. Evaluation may require imaging modalities and/or electrodiagnostic testing to confirm a nerve injury. In some cases, diagnostic injections may be needed to differentiate neuropathic versus musculoskeletal etiology. Early and accurate diagnosis is essential for treatment/management and increases the likelihood of a safe return‐to‐sport and avoidance of long‐term functional consequences. Most nerve injuries can be treated conservatively, however, severe or persistent cases may require surgical intervention. This monograph reviews key diagnostic, management, and preventative strategies for sports‐related peripheral nerve injuries involving the upper limb.
