BACKGROUND Palmaris longus (PL) has received a growing interest for its role in constructive surgery. Since the agenesis of PL shows a strong racial variation, it is conceivable that its prevalence on the Yoruba ethnic population in Nigeria will further confirm this phenomenon. METHODS A total of 600 subjects comprising 335 males and 265 females aged 8-60 years were used to assess the prevale...

To identify a safe entry point for needle insertion in patients with idiopathic carpal tunnel syndrome (CTS), cross-sectional images of the wrist MRI of 45 normal volunteers and 180 consecutive patients with idiopathic CTS were reviewed. Insertion of the needle from the five different entry points into the carpal tunnel was simulated by drawing a 1-pixel line, and the incidence of contact with ...

Background: The medial ulnar collateral ligament (MUCL) is the primary restraint to valgus force on elbow. Since first description of MUCL reconstruction by Jobe et al in 1986, many technical advancements have been implemented improve outcomes and reduce complications. docking technique has emerged as one most commonly used techniques. Indications: Following repetitive stress elbow during overh...

The aim of this study was to analyse the electromyographic (EMG) power spectrum indicating differences in the frequency bands of the spectrum resulting from differences in muscle type and force level for the extensor digitorum (ED), palmaris longus (PL) and biceps brachii (BB) muscles. The study was performed on 12 young men as 2 tests different in terms of the type of exerted force (30, 15 and...

In this study four pairs of Ag/AgCl surface electrodes respectively that pasted on the muscle belly of the biceps, triceps in the upper arm, palmaris longus and the brachioradialis muscle in the forearm are used to collect the electromyography (EMG) signals of six patterns of upper limb movements. The feature vectors of the EMG are extracted by wavelet decomposition method, and then these featu...

This study reports an objective assessment of postoperative function of 11 triple transfers for high radial palsies, using pronator teres for wrist extension, flexor carpi ulnaris for finger extension and palmaris longus for thumb extension. The mean follow-up was 3.3 years. Assessment was done by recording the active ranges of wrist motion, grip strength, wrist and finger strength and work sim...
