A Morphometric Analysis of Hamate Autograft for Proximal Scaphoid Reconstruction.

 Recently, authors have investigated using the proximal hamate as osteochondral autograft for proximal pole scaphoid reconstruction in the case of nonunion with avascular necrosis. The aim of our study was to analyze the morphology and anatomic fit of the proximal hamate compared with the proximal pole of the scaphoid using cadaveric specimens.  Ten cadaver specimens (five males and five females) were dissected.

Early complications of acromioclavicular joint reconstruction requiring reoperation.

Purpose: Prior studies have reported high complication rates with acromioclavicular joint reconstruction (ACJR). However, many of these reports have suffered from small sample sizes and inclusion of older surgical techniques. The purpose of this study was to determine the rates of early complications requiring reoperation in patients treated with ACJR.

Stress fractures of the lateral rays in the cavovarus foot: indication for surgical intervention.

Lateral ray stress fractures are a known complication of the cavovarus foot deformity. Malpositioning of the forefoot and hindfoot leads to increased pressure on the heel and lateral rays, resulting in significant morbidity. Patients with nonprogressive deformities can be managed surgically or nonsurgically in an attempt to decrease adverse events.

The suitability of human adipose-derived stem cells for the engineering of ligament tissue.

Rupture of the anterior cruciate ligament (ACL) is the one of the most common sports-related injuries. With its poor healing capacity, surgical reconstruction using either autografts or allografts is currently required to restore function. However, serious complications are associated with graft reconstructions and the number of such reconstructions has steadily risen over the years, necessitating the search for an alternative approach to ACL repair.

Variant of the extensor pollicis tertius: a case report on a unique extensor muscle to the thumb.

Variations on muscular and tendinous connections of the hand occur frequently in the human population and are often discovered during routine surgical procedures and cadaveric dissections. A knowledge of such anomalies is important to the physician in order to avoid unintentional damage to healthy tendons during surgical procedures. In addition, accessory tendons have the potential to be used in the repair or replacement of damaged tendons through surgical transfer or transplantation.

Liquid flow focused by a gas: jetting, dripping, and recirculation.

The liquid cone-jet mode can be produced upon stimulation by a coflowing gas sheath. Most applications deal with the jet breakup, leading to either of two droplet generation regimes: Jetting and dripping. The cone-jet flow pattern is explored by direct axisymmetric volume of fluid (VOF) numerical simulation; its evolution is studied as the liquid flow rate is increased around the jetting-dripping transition.
