There is an assortment of professionals that could benefit from the use of such a device. The Wartenberg Pinwheel saw widespread use in Germany before being accepted into the United States by chiropractors, orthopedists, neurosurgeons, neurologists, physical therapists, and more. Robert Wartenberg, M.D ;A SIGN OF ULNAR PALSY ;JAMA. 1939;112(17):1688. doi:10.1001/jama.1939.62800170002011a. A cadaveric study [8] investigated the impact of the radialization of the extensor digiti minimi (EDM) at the level of the fifth metacarpophalangeal (MCP) joint and reroutes it from the fifth to fourth extensor compartment. The study was done in 16 freshly frozen cadaver hands sectioned at mid-forearm.The authors concluded that the key to correct abduction deformity of the little finger is radialization of the EDM, which can be done through a solitary incision at the level of the MCP joint. Rerouting alone does not correct the abduction deformity, and in combination with radialization it does not predictably enhance the correction. The first literature regarding this sign appears to be the Letter to the Editor By Robert Wartenberg himself at 1939. In this ,he emphasize the diagnostic importance of this sign in ulnar nerve neuropathy which is not documented. The author further describes "this sign consists of position of abduction assumed by the little finger. Sometimes the fourth finger too has a tendency to assume a position of abduction, but usually it is only the little that is found in abnormal position. It was found to be most conspicuous when the patient was asked to extend his finger at the proximal joints. The importance of this sign has become increasingly evident from numerous experiences which indicate that this tendency of the little finger to be abducted may constitute an early (in some cases the first) and also a late sign of ulnar palsy".

From the physiological standpoint , this sign is easily understandable. Adduction of the little finger is performed by the interosseous and abduction by the hypothenar muscles. Both groups of the muscles are innervated by the ulnar nerve. However, in abduction of the little finger, the extensor digiti minimi and the branch to the little finger of extensor digitorum communis also play a definite part.These both are innervated by radial nerve. If the muscles innervated by the ulnar nerve are weak, those innervated by the intact radial nerve predominate in strength and abduct the little finger. Thus it is understandable why this abduction of the little finger is best seen when extensor digitorum communis comes into action and extends the fingers and the hand. In cases with the combined palsy of ulnar nerve and radial nerve ,this sign would not be present" explains the author. The Wartenberg Pinwheel has a simple yet powerful design that leaves your sensory nerves excited. The frontal part of this device is made up of a wheel with evenly distributed spikes. In action, the pins provide uniform sensations that can make your lover melt in front of you. Connected to the spiked wheels is an ergonomically designed handle that allows easy use of the toy to torture the submissive with the intended pain or pleasure. Dutton, M. (2008). Orthopaedic: Examination, evaluation, and intervention (2nd ed.). New York: The McGraw-Hill Companies, Inc. There are also chrome-plated iron and plastic Wartenberg Pinwheels in the market. Chrome-plated iron Wartenberg Pinwheels are relatively cheaper than the stainless-steel models. However, these devices may rust after some days of use, increasing infection risks. For that reason, avoid chrome-plated iron models or be extra careful when using them to avoid causing harm to your lover. Plastic Wartenberg Pinwheels are also cheaper than stainless steel variants. Plastic pinwheels come in various colors, allowing you to choose what fits the session’s mood or your outfit. However, they are not as durable as other types. Sterilizing them is also challenging; hence not ideal for group sex. When it comes to pinwheel material, your safety should take precedence. Then, you can consider the budget and durability of the toy. It is used by rolling the Wartenberg Pinwheel over the problem area of the body. Its ergonomic handle design and compact size make it easy to handle and appropriately use while performing a wide variety of tests, such as pain perception responses or reactivity and sensitivity of skin or nerves. No sterilization is needed, there is no possibility of cross-contamination since the product is single-use, and it's made in the United States.

Kilgus M , Burg D, Loss M, Weishaupt D, Meyer VE.: Wartenberg's Sign of Ulnar Nerve Lesion. A Contribution to Pathophysiology and to the Differential Diagnosis; Handchir Mikrochir Plast Chir. 2003 Jul;35(4):2518. David J. Magee: Orthopedic Physical Assessment: chapter 6-elbow ;sixth edition; Elsevier Health Sciences, 2008 Although people focus more on whips, paddles, and floggers, the Wartenberg Pinwheels is a sensation play sex toy that is a game-changer in sensory modification. The impact of these medical fetish toys can be seen in the glowing face of the sex world. If you have always wanted to experiment with them after a stimulating experience in the hospital, this is a must-read guide for you.

Unlike many BDSM sex toys, using a Wartenberg Pinwheel alone is easy. If you find the right position, you can use this toy to stimulate the sensory nerves on your genitals, legs, or stomach. Use blindfolds to restrict your sense of sight for added stimulation. As there is no general consensus regarding the aetiology of the Wartenberg's sign, managment cannot be attempted for the sign alone. Hene it would be optimal to analyse the reason for the abducted posture of the little finger and can be managed accordingly. There are few surgical procedures documented for the correction of abduction deformity of the little finger.Sensory play is slowly becoming a new normal in many romantic relationships. Couples are looking for new ways to add pleasure to their sex lives. If you are among these couples, then the Wartenberg Pinwheel BDSM sex toy guide will be great and add to your sex toys collection. The history of this toy is quite interesting and its impact is mind-blowing. It can take your sensational and bondage play to the next level. A study by Goldman et al (2009) [5] adopted the technique to assess Wartenberg's Sign - The patient is placed with wrist in neutral position and forearm fully pronated and instructed to perform full extension of all the fingers. Once digits are extended patient is asked to fully abduct all fingers and then adduct all fingers. A positive sign is indicated with the observation of abduction of the 5th digit, with the inability to adduct the 5th finger when extended. This is where stainless steel Wartenberg Pinwheels gain an advantage over plastic and chrome-plated iron Pinwheels. To experiment, heat the metal pinwheel in warm water or cool it in the freezer. After heating or cooling the wheel, test it on your body to confirm if the temperatures are manageable. Once you are ready, run the hot or cold toy on your lover’s sensitive spots and watch them moan in pleasure. Whipping and spanking make the skin highly sensitive. Take advantage of this to introduce your wheel for further stimulation and deep orgasm. If you do not have impact play tools, including floggers, whips, and paddles, use your hand to slap, pinch or bite your lover’s nipples to heighten sensitivity.

It is seen that the author (Robert Wartenberg) had not prescribed a specific technique to assess the sign. The literature describes few techniques of assessment based on the explanation given by the author. Goldman SB, Brininger TL, Schrader JW, Curtis R, Koceja DM.

Pounce wheels resemble standard Wartenberg wheels in shape but have wooden or plastic handles.
