“…The piriformis muscle may be irritated in either conjunction with other structures or secondary to other disorders such as hip or sacroiliac joint disease (1). Interestingly, a case report described sciatic neuritis as being caused by an adductor muscle strain in a human patient (7). The adductor muscle tendon insertion runs adjacent to the sciatic nerve.…”

The present study aimed to describe the ultrasonography technique and analyze the ultrasonographic findings of the proximal sciatic nerve and deep gluteal muscles in dogs with suspected sciatic neuritis. The records of 29 dogs that underwent musculoskeletal ultrasound of the sciatic nerve and deep gluteal muscles were retrospectively evaluated. Both right and left sides were evaluated. Abnormal findings were unilateral in 28/29 (97%) of the dogs. The muscles examined included the piriformis muscle, gemelli muscles, internal obturator muscle, and medial gluteal muscle. Data included signalment, purpose of the dog, orthopedic examination findings, lameness examination findings, other diagnostic imaging findings, and ultrasonography findings. Irregular margins of the sciatic nerve were recorded in 76% of the dogs. The diameter of the sciatic nerve on the affected limb was significantly larger than the nerve on the contralateral, unaffected side (p < 0.00001). The mean ± standard deviation (SD) of the sciatic nerve inner diameter between the unaffected and affected limbs was 15 ± 14.66%. The mean ± SD in sciatic nerve outer diameter was 12 ± 7.71%. Abnormal ultrasonographic findings in at least one of the examined muscles were found in 28/29 (97%) of the dogs and included changes in echogenicity in 28/29 (97%) of the dogs, loss of detail in muscle fiber pattern in 5/29 (17%) of the dogs, and impingement between the sciatic nerve and piriformis muscle in 6/29 (21%) of the dogs. The most common underlying diagnosis was lumbosacral stenosis in 9/29 (31%) of the dogs. The most common sport was agility for 21/29 (71%) of the dogs. Repetitive jumping may predispose to both lumbosacral disease, through dynamic compression, and changes within the piriformis muscle, due to overuse of the muscle leading to irritation to sciatic nerve. Ultrasonography is considered a safe and non-invasive diagnostic method to evaluate the sciatic nerve and deep gluteal muscles of dogs, and provides additional guidance for diagnostics and rehabilitation planning. This is the first study documenting ultrasonography findings in a case series of the sciatic nerve and deep gluteal muscles and their pathology in dogs.

Introduction: Sciatic neuropathy is one of the most important neuropathies of the lower extremity. Although electromyography (EMG) is useful for detecting and localizing neurologic damage, assessing the severity of neuropathy, determining prognoses, and detecting confounding or accompanying neurologic pathologies, electrodiagnostic analyses of sciatic neuropathy are rare in the literature. Methods: The EMG database between 2017 and 2022 was reviewed. Neurophysiologic data of 58 patients who were electrophysiologically diagnosed as having sciatic neuropathy were included in the study. The adult patient group was divided into three groups, injection trauma, noninjection trauma, and other etiologies for subgroup analyze. Pediatric patients were not divided into subgroups because of their limited number. Results: Sciatic neuropathy was found in nine patients in the pediatric group, and 48 patients in the adult group. Sciatic neuropathy was left sided in six (66.7%) pediatric patients and 25 (52%) adult patients. It was bilateral in one adult patient. There was no significant difference between the groups in terms of nerve conduction studies. No statistically significant difference was found in the needle EMG of the gastrocnemius medialis, tibialis anterior (TA), and biceps femoris short-head muscles (P = 0.78, P = 0.32, and P = 0.14, respectively). In both injection and noninjection trauma patients, the most common needle EMG findings in the gastrocnemius medialis muscle were detected as grade 2. Grades 3 and 4 findings were observed predominantly in peroneal division innervated TA and biceps femoris short-head muscles. Conclusion: The most common etiology of sciatic neuropathy in adults was injection-related trauma. The peroneal division is more prone to injury in sciatic neuropathy in the context of sciatic variations. Consequently, we considered that the degree of damage in noninjection traumas might be higher in both distal and proximal segments compared with injection traumas.
