Treatment of Intra-Articular Distal Phalanx Fractures in Baseball Players by Joint Distraction and Early Mobilization Using a New Dynamic External Finger Fixator.

J Hand Surg Asian Pac Vol 2021 Mar;26(1):112-117

Department of Orthopaedic Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan.

In baseball players, a high degree of functional recovery is required for the treatment of fractures in the distal interphalangeal (DIP) joint, especially on the throwing side. While dynamic external fixation is a useful treatment option to restore the joint function, existing external fixators are too large for use on DIP joints. Three cases of DIP joint intra-articular comminuted fractures in baseball players treated using the new dynamic external finger fixator which we developed are reported. Read More

Department of Orthopaedics and Sports Medicine, Seattle Children's Hospital, Seattle, WA, USA.

Purpose: Paediatric hand injuries are a frequent reason for acute medical evaluation. Previous studies have reported only fracture rates, surgical injuries or are limited to database diagnosis coding. The average fracture rates and injury distributions across the hand for all mechanical injuries have not been well-described. Read More

Irreducible Dislocations of the Proximal Interphalangeal Joint: Algorithm for Open Reduction and Soft-tissue Repair.

Plast Reconstr Surg Glob Open 2018 May 18;6(5):e1729. Epub 2018 May 18.

Hand Surgery, Kantonsspital Baselland, Liestal, Switzerland.

The "jammed finger" is among the most common hand injuries and may include simple sprains, dislocations, fractures, and fracture-dislocations. In contrast, irreducible dislocations of the proximal interphalangeal joint are rare injuries. However, they must not be overlooked in the primary assessment, because persistent subluxation may lead to joint contracture, severely compromising hand function. Read More

Adductor pollicis jamming injuries in the professional baseball player: 2 case reports.

J Hand Surg Am 2013 Jun;38(6):1181-4

Department of Orthopaedic Surgery, Tufts Medical Center, Boston, MA02462, USA.

We characterize a mechanism of injury, injury pattern, and treatment algorithm for adductor pollicis myotendinous injuries in 2 professional baseball players. Similar to myotendinous eccentric injuries in other anatomical areas, the adductor pollicis sustains a sudden forceful eccentric load during a jammed swing, resulting in intramuscular strain or tendon rupture. Based on the reported injury mechanism, and magnetic resonance imaging features of these myotendinous injuries, the thumb of the top hand during a jammed swing was suddenly and forcefully eccentrically abducted from a contracted and adducted position, resulting in injury patterns.

Jamming of fingers: an experimental study to determine force and deflection in participants and human cadaver specimens for development of a new bionic test device for validation of power-operated motor vehicle side door windows.

Biomed Tech (Berl) 2013 Feb;58(1):39-49

Elbe Clinic Stade Buxtehude, Department of Handsurgery, Aesthetics and Plastic Surgery, Stade, Germany. bernd.

The deformability of human fingers is central to addressing the real-life hazard of finger jamming between the window and seal entry of a power-operated motor vehicle side door window. The index and little fingers of the left hand of 109 participants and of 20 cadaver specimens were placed in a measurement setup. Participants progressively jammed their fingers at five different dorsal-palmar jam positions up to the maximum tolerable pain threshold, whereas the cadaver specimens were jammed up to the maximum possible deflection.

[Jamming a child's finger: an experimental study to determine elastic resistance and the point of onset of bone/joint deformation].

Handchir Mikrochir Plast Chir 2012 Jan 1;44(1):1-4. Epub 2012 Mar 1.

Rhön Klinikum AG, Klinik für Handchirurgie, Bad Neustadt Saale. Bad Neustadt Saalebernd.hohendorff

Knowledge of the elastic properties of children's fingers is very important to understand the potential hazard for jamming injuries that exists in modern motor vehicles with automatic power-operated windows. This study determined the elastic resistance and the point of onset of bone/joint deformation at each of 5 different jam positions of a child's finger under continuous dorsal-palmar compression. An unembalmed finger that recently had been surgically removed from a polydactylic 8 month-old girl was jammed in a custom hydraulic test apparatus. Read More

Finger injuries caused by power-operated windows of motor vehicles: an experimental cadaver study.

Injury 2012 Jun 17;43(6):903-7. Epub 2012 Feb 17.

Rhön Klinikum AG, Klinik für Handchirurgie Bad Neustadt Saale, Salzburger Leite 1, D-97616 Bad Neustadt a. d. Saale, Germany.

The aim of this experimental cadaver study was to investigate which kinds of lesions could occur in jam events between the glass and seal entry of power-operated motor vehicle side door windows at two different closing forces. Ten hands of fresh cadaver specimens were used. Three different hand positions chosen to simulate real events in which a finger is jammed between the glass and seal entry of the window of a current motor vehicle were examined. Read More

Lengths, girths, and diameters of children's fingers from 3 to 10 years of age.

Ann Anat 2010 May 3;192(3):156-61. Epub 2010 Apr 3.

Klinik für Handchirurgie Bad Neustadt Saale, 97616 Bad Neustadt a. d. Saale, Germany.

We obtained data on the lengths, girths, and diameters of the fingers of children from 3 to 10 years of age. A total of 160 children (78 girls, 82 boys) were examined in a cross-sectional investigation. The length of each finger of the right hand of every child was measured, as were the girths of the proximal, middle, and distal phalanges, and of the proximal and distal interphalangeal joint.

Decompaction and fluidization of a saturated and confined granular medium by injection of a viscous liquid or gas.

Phys Rev E Stat Nonlin Soft Matter Phys 2008 Nov 6;78(5 Pt 1):051302. Epub 2008 Nov 6.

Laboratoire de Physique et Mécanique des Milieux Hétégogènes (PMMH), UMR 7636 CNRS, ESPCI, Université Paris 6, Paris Cedex 05, France.

We compare quantitatively two experimental situations concerning injection of a miscible fluid into an initially jammed granular medium saturated with the same fluid, confined in a Hele-Shaw cell. The two experiments are identical, apart from the interstitial and injected fluid, which is in one case air injected into a dry granular packing, and in the other case silicone oil injected into a dense suspension. In spite of the strong differences regarding the nature of the two fluids, strikingly similar dynamical and geometrical features are identified as functions of the control parameters: cell thickness and applied fluid injection pressure.

Granular fingers on jammed systems: new fluidlike patterns arising in grain-grain invasion experiments.

Phys Rev Lett 2007 Aug 6;99(6):068001. Epub 2007 Aug 6.

Departamento de Física, Universidade Federal de Viçosa, 36570-000, Viçosa, MG, Brazil.

In this Letter we report spontaneous pattern formation in dense granular assemblies confined to a Hele-Shaw cell and quasistatic regime. Varied unexpected patterns, ranging from rounded to fingered, are observed due to the displacement of one granular material by another. Computer simulations reproduce the major features observed in these experiments. Read More

Volar Plate Injuries.

Phys Sportsmed 1982 Jan;10(1):77-84

In brief The common "jammed finger" occurs at the proximal interphalangeal (PIP) joint and is too often minimized by the coach and player and inadequately treated by the physician. Unless appropriately diagnosed and treated, volar plate injuries at that joint may result in permanent limitation of motion. The volar plate can be injured when the athlete misses a Frisbee throw or a basketball pass, because these activities force hyperextension of the PIP joint and tear the volar plate away from its insertion.
