Pianism: Performance Communication and the Playing Technique.

Authors:
Barbara James

Front Psychol 2018 5;9:2125. Epub 2018 Nov 5.

School of Human Movement and Nutrition Sciences, The University of Queensland, Brisbane, QLD, Australia.

A pianist's movements are fundamental to music-making by producing the musical sounds and the expressive movements of the trunk and arms which communicate the music's structural and emotional information making it valuable for this review to examine upper-body movement in the performance process in combination with the factors important in skill acquisition. The underpinning playing technique must be efficient with economic muscle use by using body segments according to their design and movement potential with the arm segments mechanically linked to produce coordinated and fluent movement. Two physiologically and pianistically important actions proposed by early music scientists to deliver the keystroke involve dropping the hand from the shoulders toward the keys via a wave action with the joints activated sequentially, and forearm rotation to position the fingers for the keystroke, an action followed by the elbow/upper-arm rotating in the opposite direction.

Inverse remodelling algorithm identifies habitual manual activities of primates based on metacarpal bone architecture.

Biomech Model Mechanobiol 2018 Nov 9. Epub 2018 Nov 9.

Institute of Lightweight Design and Structural Biomechanics, TU Wien, Getreidemarkt 9/BE, Vienna, Austria.

Previously, a micro-finite element (micro-FE)-based inverse remodelling method was presented in the literature that reconstructs the loading history of a bone based on its architecture alone. Despite promising preliminary results, it remains unclear whether this method is sensitive enough to detect differences of bone loading related to pathologies or habitual activities. The goal of this study was to test the sensitivity of the inverse remodelling method by predicting joint loading histories of metacarpal bones of species with similar anatomy but clearly distinct habitual hand use.

The missing segment of the autopod 1st ray: new insights from a morphometric study of the human hand.

J Anat 2018 Dec 14;233(6):828-842. Epub 2018 Oct 14.

Department of Surgical and Morphological Sciences, University of Insubria, Varese, Italy.

Whether the 1st segment of the human autopod 1st ray is a 'true' metapodial with loss of the proximal or mid phalanx or the original basal phalanx with loss of the metacarpal has been a long-lasting discussion. The actual knowledge of the developmental pattern of upper autopod segments at a fetal age of 20-22 weeks, combined with X-ray morphometry of normal long bones of the hand in the growing ages, was used for analysis of the parameters, percentage length, position of epiphyseal ossification centers and proximal/distal growth rate. The symmetric growth pattern in the fetal anlagen changed to unidirectional in the postnatal development in relation to epiphyseal ossification formation. Read More

A Geometric Morphometric Examination of Hominoid Third Metacarpal Shape and Its Implications for Inferring the Precursor to Terrestrial Bipedalism.

Authors:
Thomas R Rein

Anat Rec (Hoboken) 2018 Oct 17. Epub 2018 Oct 17.

Department of Anthropology, Central Connecticut State University, New Britain, Connecticut.

The third metacarpal has been a focus of study when examining questions surrounding early hominin locomotion since this bone is adapted to the diverse range of positional behaviors performed by extant hominoids. The shape of this bone is potentially under strong selective pressure related to the biomechanical demands of terrestrial knuckle-walking, arboreal clambering, and brachiation performed by extant hominoids since the hand directly interacts with the substrate during the performance of these movements. The objective of the present study was to explore shape variation of the third metacarpal and examine how different parts of the bone discriminated between hominoid genera that perform these different locomotor behaviors.

PeerJ 2018 9;6:e5749. Epub 2018 Oct 9.

Western Science Center, Hemet, CA, USA.

The giant tyrannosaurids were the apex predators of western North America and Asia during the close of the Cretaceous Period. Although many tyrannosaurid species are known from numerous skeletons representing multiple growth stages, the early evolution of Tyrannosauridae remains poorly known, with the well-known species temporally restricted to the middle Campanian-latest Maastrichtian (∼77-66 Ma). The recent discovery of a new tyrannosaurid, , from the Wahweap Formation of Utah provided new data on early Campanian (∼80 Ma) tyrannosaurids. Read More

Treatment of Kienböck's Disease With Neutral Ulnar Variance by Distal Capitate Shortening and Arthrodesis to the Base of the Third Metacarpal Bone.

J Hand Surg Am 2018 Oct 8. Epub 2018 Oct 8.

Radio-diagnosis Department, Faculty of Medicine, AL-Azhar University, Assiut, Egypt.

Purpose: We evaluated whether a surgical technique combining distal capitate shortening and arthrodesis to the base of the third metacarpal bone for the treatment of the early stages (stages II and IIIA) of Kienböck's disease with neutral ulnar variance resulted in pain relief, improvement in wrist motion, or changes in the radiographic evaluation.

Methods: This retrospective study reviewed 22 patients with early stages of Kienböck's disease with neutral ulnar variance, treated by distal capitate shortening and arthrodesis to the base of the third metacarpal bone. Patients were divided into 2 groups by disease stage: stage II (n = 12) and stage IIIA (n = 10). Read More

Reliability and Concurrent Validity of the Ring Gauge Method and the Metacarpal Head Tape Measure Method of Measuring Hand Size.

J Hand Surg Asian Pac Vol 2018 Sep;23(3):382-387

† Department of Orthopaedic Surgery, Shinshu University School of Medicine, Matsumoto, Japan.

Background: There are several methods for measuring edema of the hand. While the volumetric techniques, finger circumference measurement, and figure-of-eight techniques have undergone extensive psychometric testing, alternative methods of measuring hand size, such as circumferential finger size determination using a ring gauge (ring gauge method; RGM) and tape measurement of hand girth taken along the distal palmar crease (metacarpal head tape measure method; MHTM), have not. This study's aim is to examine the reliability and validity of the RGM and the MHTM. Read More

Novel Unidirectional Porous β-Tricalcium Phosphate Used as a Bone Substitute after Excision of Benign Bone Tumors of the Hand: A Case Series.

J Hand Surg Asian Pac Vol 2018 Sep;23(3):424-429

* Department of Orthopaedic Surgery, Faculty of Medicine, University of Tsukuba, Tsukuba, Japan.

Unidirectional porous β-tricalcium phosphate (UDPTCP; Affinos, Kuraray, Tokyo, Japan) has been in clinical use since 2015. Animal studies have confirmed the excellent potential of UDPTCP with regard to bone formation and material absorption. We present the first three clinical cases using UDPTCP as a bone substitute after curettage of benign bone tumors of the hand. Read More

Small Finger to Ring Finger Ray Transposition: Modern Surgical Technique and Case-based Review of the Literature.

Plast Reconstr Surg Glob Open 2018 Jun 15;6(6):e1793. Epub 2018 Jun 15.

Department of Orthopaedic Surgery, MetroHealth Medical Center, Cleveland, Ohio.

Ray transposition for central digital amputation has been performed following traumatic injury to the hand for decades. Small finger to ring finger ray transposition has been well described in the literature, with good functional and aesthetic outcomes reported. Originally described by Bunnell, the fourth metacarpal can be disarticulated and the fifth metacarpal base transposed with reconstruction of the intermetacarpal ligament allowing progressive closure between the third and fifth rays.

Comparing biomechanical strength of unicortical locking plate versus bicortical compression plate for transverse midshaft metacarpal fracture.

J Orthop Surg (Hong Kong) 2018 May-Aug;26(3):2309499018802511

Department of Orthopaedic Surgery (NOCERAL), Faculty of Medicine, University of Malaya, Kuala Lumpur, Malaysia.

Purpose: Metacarpal bone fractures constitute 10% of all fractures. Unstable metacarpal fractures require surgical intervention, which poses danger to flexor tendon either due to bicortical drilling or construct of the implant. Unicortical locking plate fixation may be the solution to preventing flexor tendon injury. Read More

Tether Creation Between the Second and Third Extensor Digitorum Communis for Third Extensor Tendon Subluxation at the Metacarpophalangeal Joint.

Tech Hand Up Extrem Surg 2018 Dec;22(4):146-149

Yukioka Hospital Hand Center, Osaka Yukioka College of Health Science, Kita-ku, Osaka-shi, Osaka, Japan.

We developed a substitution technique for a sagittal band reconstruction for subluxation of the third extensor tendon at the metacarpophalangeal joint. Through this procedure, we attempted to supply a tether between the second and third extensor digitorum communis (EDC) tendons. A half-slip of the second EDC was interlaced to the third EDC tendon at the level of the third metacarpal head with the metacarpophalangeal joint in full flexion position; this ensured that the interlace of the graft serves as a direct stabilizer against ulnar subluxation.
