Long-Term Donor-Site Morbidity After Free, Nonvascularized Toe Phalanx Transfer for Congenital Differences of the Hand.

Purpose: Toe phalanx transplantation is a well-established technique for addressing bony deficiency in the reconstruction of hypoplastic digits in patients with congenital differences of the hand. Prior studies have commented on varying degrees of donor-site morbidity, although assessment of morbidity with validated outcome scores is lacking. This study seeks to evaluate donor-site morbidity after toe phalanx harvest using validated outcome measures.

Biomechanical Comparison of Standard and Linked Single-Row Rotator Cuff Repairs in a Human Cadaver Model.

Purpose: The purpose of this study was to evaluate the time zero cyclic and failure loading properties of a linked single-row rotator cuff repair compared with a standard simple suture single-row repair using triple-loaded suture anchors.

Methods: Eighteen human cadaveric shoulders from 9 matched pairs were dissected, and full-thickness supraspinatus tears were created. The tendon cross-sectional area was recorded.

Accuracy of 3-Tesla magnetic resonance imaging for the diagnosis of intra-articular knee injuries in children and teenagers.

Background: Magnetic resonance imaging (MRI) is a commonly used tool for the diagnosis of intra-articular knee pathologies. Although many studies have reported the accuracy of MRI in the adult population, fewer studies have investigated these tests in younger patients. Furthermore, these studies have shown a higher variability in both the sensitivity and the specificity of MRI for these knee injuries in this age group.

Nutritional status influences socially regulated foraging ontogeny in honey bees.

In many social insects, including honey bees, worker energy reserve levels are correlated with task performance in the colony. Honey bee nest workers have abundant stored lipid and protein while foragers are depleted of these reserves; this depletion precedes the shift from nest work to foraging. The first objective of this study was to test the hypothesis that lipid depletion has a causal effect on the age at onset of foraging in honey bees (Apis mellifera L.
