sensory dysfunction in the great toe in hallux valgus
Journal of Bone and Joint Surgery-british Volume, 2004Co-Authors: M L Herron, D J Beard, Pippa BinfieldAbstract:Injury to the dorsomedial cutaneous nerve in the foot may occur after operations for hallux valgus. Pressure neuropathy before operation is also described but remains largely unexplored. We have investigated the incidence of sensory deficit in the great toe before operating for hallux valgus and examined to what extent any deficit was related to the degree of angulation of the joint. Forty-three patients with a total of 61 great toes with hallux valgus presenting for consideration of surgical correction had their sensation tested in pre-designated zones using a five-filament set of Semmes-Weinstein Monofilaments. These allowed good inter-observer reliability with an intra-class correlation coefficient of 0.84. Sensory symptoms were noted by only 21% of the patients, a measurable reduction in sensation by one monofilament grade or more was found in an additional 44%. No relationship was found between the degree of sensory loss and the degree of angulation. Patients with symptomatic hallux valgus may have sensory loss in the toe without being aware of it. Normal subjective sensation does not reliably predict normal sensory function. Given the potentially high rates of nerve damage following operations for hallux valgus, we recommend objective sensory testing as part of routine assessment before surgery.

PREOPERATIVE SENSORY DYSFUNCTION OF THE GREAT TOE IN HALLUX VALGUS
2003Co-Authors: M L Herron, D J Beard, Pippa BinfieldAbstract:Injury to the dorsomedial cutaneous nerve has been identified as a potentially frequent occurrence after hallux valgus surgery. The existence of pre-operative pressure neuropathy is also described but remains largely unexplored. This study was performed to investigate the incidence of pre-operative sensory deficit in the hallux valgus toe, and to examine to what extent any deficit was related to the degree of joint angulation. A cohort of 43 patients (61 hallux toes) presenting for consideration of surgical correction had their sensation tested in pre-designated sensory zones using a five-filament set of Semmes-Weinstein Monofilaments. These allowed good inter-observer reliability with an ICC (intra-class correlation coefficient) of 0.84 overall. Whilst sensory symptoms were self reported in only 21% of the feet, a measurable reduction in sensation by one monofilament grade or more was found in an additional 44% of the feet. No relationship was found between the degree of sensory loss and degree of angulation. Patients with symptomatic hallux valgus may have sensory loss of the toe despite not being aware of the deficit. Normal subjective sensation does not reliably predict normal sensory function. Given the potentially high rates of intra-operative nerve damage in hallux surgery we recommend objective sensory testing as part of routine pre-operative assessment.

fabrication of bamboo structure hollow polyester Monofilaments for extraordinary compression properties
Composite Structures, 2019Co-Authors: Xiaohui Zhang, Xin WangAbstract:Abstract Owing to its special structure, bamboo can withstand larger load in nature. The novel structure of bamboo is a great example for exploring materials with excellent mechanical properties, though limited research in this area has been reported so far. In textiles, Monofilaments with outstanding compression property are desired in the development of warp-knitted spacer fabrics for a range of applications. Herein, we use 3D printing method to fabricate polyester (PET) bamboo-structure Monofilaments and study their compression properties. It has been found that bamboo-structure hollow monofilament undertakes more load per unit mass than solid and continuous hollow Monofilaments, and the value of load per unit mass increases with the increase of the hollow part. FEM analysis has discovered that the compression behavior and the compression properties of the bamboo-structure monofilament are in accordance with that of spacer monofilament in warp-knitted spacer fabrics. Warp-knitted spacer Monofilaments prepared from bamboo-structure hollow monofilament with a high percentage of hollow part undertake more load per unit mass, providing new opportunities on the design and development of warp-knitted spacer monofilament towards different applications.

fifty years of somatosensory research from the semmes weinstein Monofilaments to the weinstein enhanced sensory test
Journal of Hand Therapy, 1993Co-Authors: Sidney WeinsteinAbstract:Abstract In this paper, the author's long history with somatosensation is overviewed with special emphasis on the creation of objective tests of sensibility. Objective testing is discussed using numerous examples from the author's experiences. The creation of the Semmes-Weinstein Monofilaments is discussed. Tests employing the Semmes-Weinstein Monofilaments, two-point discrimination, and point localization are discussed with reference to the fact that these tests reflect specific differences between the central and peripheral nervous systems. Towards that end, contrasts are made between the Semmes-Weinstein esthesiometer and both the two-point discrimination and the point-localization tests. A new enhancement of the original Semmes-Weinstein monofilament test, the Weinstein Enhanced Sensory Test * (WEST * ), is introduced. Advantages of the WEST are discussed.
