OBJECTIVE To demonstrate the prevalence and characteristics of subclinical ulnar neuropathy at the elbow in diabetic patients. METHODS One hundred and five patients with diabetes mellitus were recruited for the study of ulnar nerve conduction analysis. Clinical and demographic characteristics were assessed. Electrodiagnosis of ulnar neuropathy at the(More)
BACKGROUND It is important to understand the anatomical relationship between the medial and lateral branches of superficial radial nerve (SRN) and the first dorsal compartment to prevent and minimize possible injury to these nerves during various procedures around the tip of radial styloid process (RSP). OBJECTIVE To delineate the anatomical location of(More)
OBJECTIVES To investigate pronator quadratus (PQ) anatomy and determine the proper volar needle insertion point based on landmarks, the tip of the ulnar styloid (an imaginary vertical line passing the tip of the ulnar styloid process [U line]), and the ulnar margin of the palmaris longus tendon (uPL) using ultrasonography. DESIGN Descriptive study. (More)
OBJECTIVE To determine the midpoint (MD) of extensor hallucis longus muscle (EHL) and compare the accuracy of different needle electromyography (EMG) insertion techniques through cadaver dissection. METHODS Thirty-eight limbs of 19 cadavers were dissected. The MD of EHL was marked at the middle of the musculotendinous junction and proximal origin of EHL.(More)
A 35-year-old man with Buerger_s disease reported persistent, sharp, and stabbing pain in the medial heel for 1 year that did not improve by conservative management modalities including medications and physical therapy and surgical exploration around the medial foot. The pain was rated as 8 on a visual analog pain scale of 10. The incision site for previous(More)
An accessory navicular bone (AN) is the most common accessory ossicle in the foot. The presence of an AN bone can trigger various foot problems, such as posterior tibial tendon pathology, flattening of the medial longitudinal arch, and medial foot pain. Despite the clinical influence of presence of an AN in foot disease, the research regarding its(More)
OBJECTIVE To find the optimal needle insertion site for needle electromyography of the pronator teres (PT) muscle among commonly used sites. METHODS Fifty forearms of 25 healthy subjects were evaluated. Four expected needle insertion points were designated as follows. Point 0 was positioned at the midpoint between the medial epicondyle and medial border(More)
