Forces imparted by the fingers onto a baseball are the final, critical aspects for pitching, however these forces have not been quantified previously as no biomechanical technology was available. In this study, an instrumented baseball was developed for direct measurement of ball reaction force by individual fingers and used to provide fundamental information on the forces during a fastball pitch. A tri-axial force transducer with a cable having an easily-detachable connector were installed in an official baseball...

The following report provides clinical follow-up on a National Football League player who sustained a complete cervical spinal cord injury (SCI) while tackling an opposing player in 2007. He received prompt medical and surgical care based on then-current recommendations, but was also treated with systemic hypothermia soon after his injury, which was controversial at the time. Since then, smaller randomized human studies have described the tolerable safety profile, efficacy, and potential benefits of this intervention in acute SCI in humans...

RATIONALE: Slowly progressive hand ischemia is mostly associated with medical illness such as vasculitis, and in patients with smoking history, Buerger disease is often considered first. However, despite the very low incidence of vascular anatomical anomalies, they can lead to hand ischemia. And if there is no consideration for them, proper treatment cannot be selected. PATIENT CONCERNS: A 42-year-old male smoker presented with a slowly progressing 5th fingertip necrosis following blunt trauma...

Management of fingertip and thumb tip injuries has recently undergone substantial changes. The time-proven traditional armamentarium of local flaps has been expanded and replaced by a wide variety of flaps. Simultaneous with the development of new flaps, the conservative treatment of fingertip and thumb tip injuries with semiocclusive dressings has also become a more acceptable treatment for these injuries. The excellent results with respect to restoring contour, sensibility of the pulp, and aesthetics of the finger justify this more tedious and time-consuming treatment of fingertip and thumb tip injuries...

Fingertip injuries are a common problem. There may be pulp loss and exposed bone. Various techniques have been described to reconstruct function as well as aesthetics; yet it is still unclear which treatment options should be chosen for each specific injury. Evidence-based treatment strategies are limited because there are no prospective randomized clinical trials evaluating one method with another. Fingertip injuries are usually variable in their presentation, and therefore treatment decisions are often dictated by the knowledge and expertise of the treating physician combined with the patient's unique injury...

In the assessment of hand and upper limb function, detecting sincerity of effort (SOE) for grip strength is of major importance to identifying feigned loss of strength. Measuring maximal grip strength with a dynamometer is very common, often combined with calculating the coefficient of variation (CV), a measure of the variation over the three grip strength trials. Little data is available about the relevance of these measurements in patients with median nerve impairment due to the heterogeneity of patient groups...

Users actuate touchscreen computers by applying forces with their fingers to the touchscreen, although the amount and direction of the force is unknown. Our aim was to characterize the magnitude, direction and impulse of the force applied during single finger (tapping and sliding in four directions) and two finger gestures (stretch and pinch). Thirteen subjects performed repeated trials of each gesture. Mean(±SD) resultant force was 0.50(0.09)N for tap, 0.79(0.32)N to 1.18(0.47)N for sliding gestures, 1.47(0...

BACKGROUND: Fingertip amputations can be debilitating and challenging to treat, due to the need for both function and cosmesis. We studied the functional outcomes of patients receiving an antegrade homodigital neurovascular island flap for fingertip amputations. METHODS: From 2004 to 2013, we performed 13 cases of antegrade homodigital neurovascular island flaps. Functional outcomes were studied. Four had Allen Zone II and nine had Zone III injuries. Seven were performed as secondary surgery...

Fingertip injury commonly results in avulsion of the nail bed. For large area defects of the nail bed with distal phalanx exposure, methods for reconstruction of soft tissue defects are scarcely mentioned in the literature.From May 2014 to January 2016, 6 patients with large area defects of the nail bed with distal phalanx exposure were enrolled. A new surgical method, cross finger fascial flap combined with thin split-thickness toe nail bed graft, was applied in all patients.All the 6 patients were followed-up at least 3 months...

Traumatic nail bed injuries to the hand are a common problem for hand surgeons. Whereas the majority of those are treated with primary repair, the remainder present significant surgical challenges to address residual soft tissue defects. In this article, we present our approach to treating injuries to the fingertips utilizing single-layer bovine acellular dermal matrix grafts.

OBJECTIVES: Nail bed injuries are common in children, with nail bed damage accounting for 15% to 24% of fingertip injuries. Our objective was to see whether medical adhesives, the cyanoacrylates including Histoacryl and Dermabond, could be used to fix nail bed lacerations as opposed to doing a primary repair with sutures, thus potentially being a quicker method for repair in the emergency department for these injuries. METHODS: We conducted a literature review using the search engines MEDLINE, PubMed, Web of Science, and Google Scholar, and the references within these articles were also integrated...

The nail provides a functional protection to the fingertips and surrounding tissue from external injuries. The nail plate consists of three layers including dorsal, intermediate, and ventral layers. The dorsal layer consists of compact, hard keratins, limiting topical drug delivery through the nail. In this study, we investigate the application of fractional CO₂ laser that produces arrays of microthermal ablation zones (MAZs) to facilitate drug delivery in the nails. We utilized optical coherence tomography (OCT) for real-time monitoring of the laser-skin tissue interaction, sparing the patient from an invasive surgical sampling procedure...

The management strategy proposed herein for fingertip amputations advocates secondary healing with preservation of appearance as well as function. Conservative healing is more likely to result in a sensate, nontender, and cosmetically acceptable fingertip compared to surgical management in many clinical scenarios. This manuscript examines in detail the extent of fingertip injury and defines the relationship of injury to final fingertip outcome. A classification is presented, which allows adequate initial counseling regarding prognosis, and predicts the need for secondary corrective surgery...

AIMS OF THE STUDY: Fingertip injuries can be treated in different ways, including shortening with primary closure, skin graft, and local or distant flaps. Several local flaps for the reconstruction of the amputated fingertip were described. We present our experience with a new concept of homodigital adipofascial reverse flap that avoids the second surgical stage and allows a complete and anatomically perfect reconstruction of nail bed, with preservation of the nail lamina. MATERIALS AND METHODS: Between March 2014 and February 2015, five patients with digital amputations (distally to the nail matrix) were treated using the Fenestrated Adipofascial Reverse (F...

The objective of this study was to observe the characteristics of the skin after irradiation with a 2790-nm yttrium-scandium-gallium-garnet (YSGG) laser using reflectance confocal microscopy (RCM). A 2790-nm YSGG laser was used to irradiate fresh foreskin (four doses, at spot density 3) in vitro. The characteristics of microscopic ablative columns (MAC), thermal coagulation zone (TCZ), and microscopic treatment zones (MTZ) were observed immediately after irradiation using digital microscope and RCM. The characteristics of MAC, TCZ, and MTZ with variations in pulse energy were comparatively analyzed...
