BACKGROUND Today, humerus nails have become the surgical method of choice in the treatment of humerus shaft fractures. Whether or not the radial nerve should be intraoperatively examined by default in case of primary paresis is currently under discussion. PATIENTS AND METHODS Clinical findings from 38 patients with humeral shaft fractures surgically treated with unreamed humerus nail (UHN) at...

background lumbar plexus block (lpb) is one of the anesthetic options in the elderly patients undergoing hip surgeries. lpb could be safe because it targets somatic nerve in psoas region. effectiveness of lpb is attributed to the sufficient analgesia provided intraoperatively as well as postoperatively. adequate muscle relaxation and immobility during surgery refers to its acceptability. object...

A series of 26 children was referred to our specialist unit with a 'pink pulseless hand' following a supracondylar fracture of the distal humerus after a mean period of three months (4 days to 12 months) except for one referred after almost three years. They were followed up for a mean of 15.5 years (4 to 26). The neurovascular injuries and resulting impairment in function and salvage procedure...

Examining the relevance of 'animal personality' involves linking consistent among- and within-individual behavioural variation to fitness in the wild. Studies aiming to do this typically assay personality in captivity and rely on the assumption that measures of traits in the laboratory reflect their expression in nature. We examined this rarely tested assumption by comparing laboratory and fiel...

The multi-robot exploration problem is to explore an unknown graph of size n and depth d with k robots starting from the same node. For known graphs a traversal of all nodes takes at most O(d + n/k) steps. The ratio between the time until cooperating robots explore an unknown graph and the optimal traversal of a known graph is called the competitive exploration time ratio. It is known that for ...

Objective: “Cheiralgia paresthetica” is the term suggested by Wartenberg in 1932, to define isolated neuropathy of the superficial branch of the radial nerve (SRN). Radial nerve compression can occur throughout its course in the forearm, especially in the tunnel region beneath the tendon of the brachioradialis muscle. The authors report three cases with review of the literatures. Methods: The a...

INTRODUCTION Laparoscopic intraperitoneal onlay mesh (IPOM) repair is occasionally used for inguinal hernia repair. Here, we report a case of chronic neuropathic pain after laparoscopic IPOM repair for inguinal hernia, which was treated successfully with laparoscopic selective neurectomy. PRESENTATION OF CASE A 59-year-old man with bilateral inguinal hernia underwent laparoscopic repair. Tran...

Dear Editor These ultrasound images (Fig. 1. Images A–D) convey an enlarged posterior interosseous nerve (PIN) with interruption of the PIN course by dislodgement of the distal of two Mitek anchors inserted 5 years previously for a biceps tendon rupture raising suspicion of PIN transection at the level of the distal biceps anchor. Surgical exploration confirmed complete PIN laceration with the ...

The Dolatabad area located in SE Iran is a well-endowed terrain owning several chromite mineralized zones. These chromite ore bodies are all hosted in a colored mélange complex zone comprising harzburgite, dunite, and pyroxenite. These deposits are irregular in shape, and are distributed as small lenses along colored mélange zones. The area has a great potential for discovering further chromite...
