“…However, these differentials mentioned demonstrate no size variability in changing the patient's position. Complications of muscle herniation may be related to pain, paresthesia and compartment syndrome [ 9 ]. Management of patients is usually conservative, and surgical procedures such as fasciotomy are reserved for cases with severe pain and nerve involvement [ 10 ].…”

Focal protrusion of the muscle through an acquired or congenital myofascial defect is termed focal muscle herniation, and overall, tibialis anterior is the most commonly affected muscle. Tibialis anterior muscle typically herniates on attaining "fencer's lunge" position. We report the case and describe the highresolution ultrasonography appearances of focal tibialis anterior muscle herniation diagnosed using provocative manoeuvres in a 32-year-old female.

Nerve entrapments related to muscle herniation

Background Muscle herniation is a muscle protrusion through a fascial defect. It is a rarely reported cause of nerve entrapment. Methods We present a case of superficial fibular (peroneal) neuropathy associated with a fibularis (peroneus) brevis muscle herniation and a review of the literature on nerve entrapments secondary to muscle herniation unrelated to compartment syndrome. Results Eleven cases of nerve entrapments secondary to muscle herniation were identified. The superficial fibular nerve (SFN) was the most commonly entrapped nerve by fibularis muscle herniation. Patients presented with pain, numbness, or paresthesias, and an often tender, small palpable mass with a Tinel sign. Muscle MRI or ultrasound identified the lesion, and patients responded well to fasciotomy. Conclusions The most commonly reported nerve entrapped by muscle herniation is the SFN secondary to fibularis muscle herniation. Characteristic clinical and imaging (MRI or ultrasound) features are diagnostic, and there is a salutary response to fasciotomy.

Utility of the H‐reflex in diagnosing polyneuropathy

Introduction An absent Hoffman (H)‐reflex, the electrophysiological equivalent of the Achilles reflex, is assumed to be one of the first detectable signs of polyneuropathy (PNP). In this study we compare the H‐ and Achilles reflexes in patients with suspected PNP to evaluate the diagnostic utility of the H‐reflex. Methods Data from clinical examination and nerve conduction studies (NCS) were analyzed in patients with suspected PNP. Results The PNP diagnosis was confirmed by follow‐up in 209 patients. The sensitivities of the H‐ and Achilles reflexes were similar (70.3% vs 71.8%), whereas the H‐reflex had higher specificity (85.2% vs 70.5%) (P < .001). Adding H‐reflex to the NCS protocol increased the diagnostic sensitivity from 80.9% to 87.6%. Discussion The H‐reflex is a sensitive method that could provide added value to standard NCS in PNP diagnosis. The simplicity and high specificity make it superior to its clinical equivalent, the Achilles reflex.
