We report here a case of epithelioid sarcoma in the forearm of a 33-year-old male presenting with symptoms and signs of carpal tunnel syndrome originating from the direct involvement of the median nerve. Due to the slow growing of the tumor, the patient noticed the presence of tumor mass in his forearm after several months from the initial onset of the symptoms. Magnetic resonance imaging showe...

INTRODUCTION Simultaneous contraction of the extensor carpi radialis longus (ECRL) with forced hyperflexion of the wrist can result in avulsion of the tendon and its bony attachment at its insertion at the dorsum of the base of the second metacarpal. This is a rare and often unreported fracture pattern. CASE PRESENTATION We present a 31- year- old male who sustained a hyperflexion injury. He ...

Abstract The coordinated cadastral database in Malaysia is known as National Digital Cadastral Database (NDCDB) with an expected accuracy of ±10cm rural and ±5cm urban area. Till date, there are approximately 7.8 million land parcels 22 boundary markers the NDCDB for whole Peninsular Federal Territory Labuan covering total area 132,183 km 2 . Since 2010, block adjustment has been carried out co...

Introduction Biceps brachii is described as a superficial muscle in the anterior compartment of the arm. It is a flexor of the elbow joint and a powerful supinator of the forearm. Standard anatomical textbooks describe the muscle as arising by two heads, a long and a short head arising from the supraglenoid tubercle and coracoid process of scapula, respectively. The two heads form a common bell...

UNLABELLED Study the morphology of the superficial branch of the radial nerve (SBRN) of the forearms and wrists of fresh adult human cadavers. METHODS Twenty three dissections were performed under 3.5x loupe magnification, histological sections of the nerve were obtained in 20 dissections for fascicle identification. RESULTS The SBRN emerged, in average, at 8.65cm proximal to the radial sty...

BACKGROUND The optimal surgical treatment for Kienböck's disease with stages IIIB and IV remains controversial. A cadaver study was carried out to evaluate the use of coiled extensor carpi radialis longus tendon for tendon interposition and a strip obtained from the same tendon for ligament reconstruction in the late stages of Kienböck's disease. METHODS Coiled extensor carpi radialis longus ...

We asked human subjects to make accurate step-tracking movements of the wrist to targets that required 5 degrees-30 degrees of radial or ulnar deviation. Speed instructions were given prior to each trial. Muscle activity was recorded from extensor carpi radialis longus (ECRL) and extensor carpi ulnaris (ECU) using surface electrodes. The agonist muscle initiated each movement with a brief burst...

INTRODUCTION Upper-extremity tendon transfer surgeries have been routinely performed since the 1970s for conditions such as stroke, paralysis, spinal muscle atrophy, nerve or muscle trauma, and congenital disorders. The surgery involves re-routing one or more tendons from an non-functioning muscle and directly suturing it to a functioning donor muscle in order to partially restore hand function...

The commonest cause of radial nerve dysfunction is from extrinsic compressions of the radial nerve, such as against the shaft of the humerus in “Saturday night palsy”. However, this chapter focuses on the less common intrinsic compression neuropathies of the radial nerve. Intrinsic radial nerve compression neuropathies occur much less frequently than those of the median or ulnar nerves. The com...
