Objectives: Muscle hypertrophy is a relatively rare condition that may cause nerve entrapment syndromes. We report the case of a 14-year-old girl with unilateral hypertrophy of the abductor hallucis muscle with entrapment of the medial plantar nerve and review the literature. Methods: Computed tomography and magnetic resonance imaging revealed unilateral hypertrophy of the abductor hallucis muscle. Results: Two injections of steroid and lidocaine at the point of tenderness resulted in resolution of the pain. Conclusions: We report a rare case of hypertrophy of the abductor hallucis muscle considered with entrapment of the medial plantar nerve. Treatment of this condition should be selected according to the pathological condition of each patient.

Abductor Hallucis Muscle

Loss of soft tissue coverage distally around the foot poses threats of amputation of the exposed boney structures. An amputation of a portion of the foot leads to loss of the biomechanical structural integrity of the foot. This promulgates an imbalance with its inherent risks of developing new ulcers. This in turn potentiates the limb loss cycle. The reverse abductor hallucis muscle flap is ideally suited for small to moderate-sized defects in the vicinity of the first metatarsophalangeal joint based on its arc of rotation. In this article, we present cases of 5 patients who failed local wound care and healing by secondary intention for at least 6 months duration. The patients were treated successfully using reverse abductor hallucis muscle flap.

Partial Release

Eighteen fresh-frozen cadaver foot specimens underwent release of the plantar fascia via a newly described endoscopic technique. A 75% release was attempted on each specimen in order to represent a partial fascial release. Each specimen was then dissected to assess the success of the procedure. Five separate measurements were recorded evaluating the reproducibility of the procedure, adequacy of the release considering accepted etiologies for chronic heel pain, and the possibility of damage to local structures. Partial release was noted to be possible, but controlling the exact percentage of the incision was difficult. The release averaged 82% of the width of the fascia, with a range of 53% to 100%. There was no damage in any specimen to the first branch of the lateral plantar nerve, the structure considered most at risk during the procedure. Release of the deep fascia of the abductor hallucis muscle was not possible with this approach.

Electrodiagnostic (EDX) patterns of neuropathic dysfunction have been based on axonal/demyelinating criteria requiring prior assumptions. This has not produced classifications of desired sensitivity or specificity. Furthermore, standard nerve conduction studies have limited reproducibility. New methodologies in EDX seem important. Recurrent Quantification Analysis (RQA) is a nonlinear method for examining patterns of recurrence. RQA might provide a unique method for the EDX evaluation of neuropathies. RQA was used to analyze F-wave recordings from the abductor hallucis muscle in 61 patients with neuropathies. Twenty-nine of these patients had diabetes as the sole cause of their neuropathies. In the other 32 patients, the etiologies of the neuropathies were diverse. Commonly used EDX variables were also recorded. RQA data could separate the 29 patients with diabetic neuropathies from the other 32 patients (P<0.009). Statistically significant differences in two EDX variables were also present: compound muscle action potential amplitudes (P<0.007) and F-wave persistence (P<0.001). RQA analysis of F-waves seemed able to distinguish diabetic neuropathies from the other neuropathies studied, and this separation was associated with specific physiological abnormalities. This study would therefore support the idea that RQA of F-waves can distinguish between types of neuropathic dysfunction based on EDX data alone without prior assumptions.

We analyzed individual motor units during electrically elicited cramp contractions with the aim of characterizing the variability and degree of common oscillations in their discharges. Intramuscular and surface electromyographic (EMG) signals were detected from the abductor hallucis muscle of 11 healthy subjects (age 27.0 ± 3.7 yr) during electrically elicited cramps. In all, 48 motor units were identified from the intramuscular EMG. These motor units were active for 23.6 ± 16.2 s, during which their average discharge rate was 14.5 ± 5.1 pulses/s (pps) and their minimum and maximum rates were, respectively, 6.0 ± 0.8 and 25.0 ± 8.0 pps ( P < 0.001). The coefficient of variation for the interspike interval (ISI) was 44.6 ± 9.7% and doublet discharges constituted 4.1 ± 4.7% of the total number of discharges. In 38 motor units, the SD of the ISI was positively correlated to the mean ISI ( R2 = 0.37, P < 0.05). The coherence spectrum between smoothed discharge rates of pairs of motor units showed one significant peak at 1.4 ± 0.4 Hz for 29 of the 96 motor unit pairs and two significant peaks at 1.3 ± 0.5 and 1.5 ± 0.5 Hz for 8 motor unit pairs. The cross-correlation function between pairs of discharge rates showed a significant peak (0.52 ± 0.11) in 26 motor unit pairs. In conclusion, motor units active during cramps showed a range of discharge rates similar to that observed during voluntary contractions but larger ISI variability, probably due to large synaptic noise. Moreover, the discharge rates of the active motor units showed common oscillations.
