BACKGROUND The posterior interosseous nerve (PIN) can be difficult to locate within the radial tunnel. The deep branch of the radial nerve (DBRN) enters the supinator muscle after passing under the arcade of Fröhse. It courses through the superficial portion of the supinator muscle to exit distally as the PIN. Anatomic landmarks could facilitate diagnosis and treatment of radial tunnel syndrome...
OBJECTIVES This study aimed to assess the relation between stent edge restenosis (SER) and the distance from the stent edge to the residual plaque using quantitative intravascular ultrasound. BACKGROUND Although percutaneous coronary intervention with drug-eluting stents has improved SER rates, determining an appropriate stent edge landing zone can be challenging in cases of diffuse plaque le...
OBJECTIVE The purpose of the present study was to identify length and landmark of proximal of A1 pulley in hand. MATERIAL AND METHOD An anatomical study of the length and landmark of A1 pulley in hand was performed in 510 fingers and thumbs from 51 preserved cadavers. There were 25 females and 26 males whose ages at the time of death ranged from 48 to 89 years. RESULTS The lengths of A1 pul...
Ten patients with metacarpophalangeal joint locking of the thumb were studied. Three of them underwent surgical release. During surgery, it was found that the radial sesamoid was seated in a cartilage defect on the volar aspect of the metacarpal head. It appeared that the defect was created by the proximal edge of sesamoid. When the abductor pollicis brevis and flexor pollicis brevis muscles we...
The success of anatomic reattachment of the tuberosities in proximal humeral fractures, treated with hemiarthroplasty, correlates with functional results. The purpose of this study was to determine the value of the upper edge of the pectoralis major insertion (PMI) as a landmark to establish the proper height and version of hemiarthroplasty implanted for proximal humeral fractures. Twenty cadav...
BACKGROUND Differences in needle design may impact nerve localization. This study evaluates the electrical properties of two insulated Tuohy needles using computational finite element modeling. METHODS Three-dimensional geometric computer-based models were created representing two 18-gauge, insulated Tuohy needles: (1) with an exposed metal tip and (2) with an insulated tip. The models were p...
PURPOSE The purpose of this study was to investigate the effect of partial excision of the A2 pulley on the gliding resistance and the strength of the residual pulleys in a human in vitro model with or without tendon repair. METHODS We used 32 cadaveric human fingers from 11 cadavers. The A2 pulley was excised successively 25%, 50%, and 75%, cutting either from the distal toward the proximal ...
BACKGROUND On the basis of brachytherapy experience, edge stenosis has been raised as a potential limitation for drug-eluting stents. We used serial intravascular ultrasound (IVUS) to prospectively analyze vessel responses in adjacent reference segments after implantation of polymer-controlled paclitaxel-eluting stents. METHODS AND RESULTS TAXUS II was a randomized, double-blind trial with 2 ...
Variation of recurred branch of median nerve in relation to the median and flexor retinaculum are significant for both hand surgeons and specialists always. In this study, 64 cadaver hands (32 men) have been dissected. The median nerve was identified at the proximal edge of the flexor retinaculum, and in order to expose carpal tunnel the ligament was divided, and the above subjects were studied...
OBJECTIVE To identify objective parameters to guide correct location of the posterior cruciate ligament (PCL) in the femur. METHODS The PCLs of 20 human cadavers were resected. The following portions were measured: distance from the most distal portion of the PCL, close to the roof, to the most anterior edge of the cartilage (AB); distance from the most proximal portion of the PCL, close to t...
