2019 IWIW Meeting Abstracts, Las Vegas, Wed. Sept. 4th SESSION 1: Carpal Ligament 1 Stable Central Column Theory of Carpal Mechanics Michael Sandow FRACS Wakefield Orthopaedic Clinic Adelaide, Australia Background: The carpus is a complicated and functionally challenged mechanical system and advancements in the understanding have been compromised by the recognition that there is no standard carpal mechanical system and no typical wrist. This paper cover component of a larger project that seeks to develop a kinetic model of wrist mechanics to allow reverse analysis of the specific biomechanical controls or rule of a specific patient's carpus, and then use those to create a forward mathematical model to reproduce the unique individual's anatomical motion based on the extracted rules. Objectives and Methods: Based on previous observations, the carpus essentially moves with only 2 degrees of freedom - pitch (flexion / extension) and yaw (radial deviation / ulnar deviation), while largely preventing roll (pronation / supination). The object of this paper is therefore to present the background and justification to support the rules based motion (RBM) concept states that the motion of a mechanical system, such as the wrist, is the net interplay of 4 rules - morphology, constraint, interaction and load. The Stable Central Column Theory (SCCT) of wrist mechanics applies the concept of RBM to the carpus, and by using a reverse engineering computational analysis model, identified a consistent pattern of isometric constraints, creating a "Two-Gear Four-Bar" linkage. This study assessed the motion of the carpus using a 3D dynamic visualization model, and the hypothesis was that the pattern and direction of motion of the proximal row, and the distal row with respect the immediately cephalad carpal bones or radius would be very similar in all directions of wrist motion.

It is the posture/alignment of fingers with some flexion at all the joints of digits, beginning with less flexion at the index finger, progressing to more flexion towards the little finger. The FFC may vary in individuals of different occupations as occupational activities performed over a prolonged period may have an influence on the finger flexion ROM thereby influencing the normal FFC. Understanding the variations may serve as a valuable tool to manage rehabilitation following hand injuries, which may include improving the finger flexion joint ROM suited to the need of the individual. The purpose of this study was to observe, measure and document the FFC in individuals belonging to different occupations and to analyzeMethods: whether a significant variation may be seen within the occupations and between the occupations. One hundred twenty five healthy individuals with an age ranging between 20 to 60 years who met the inclusion criteria participated in the study. Occupations included were electricians, maintenance workers and desk workers.

REVIEW ARTICLE Osteoarthritis of the Wrist
REVIEW ARTICLE Osteoarthritis of the Wrist Krista E. Weiss, Craig M. Rodner, MD From Harvard College, Cambridge, MA and Department of Orthopaedic Surgery, University of Connecticut Health Center, Farmington, CT. Osteoarthritis of the wrist is one of the most common conditions encountered by hand surgeons. It may result from a nonunited or malunited fracture of the scaphoid or distal radius; disruption of the intercarpal, radiocarpal, radioulnar, or ulnocarpal ligaments; avascular necrosis of the carpus; or a developmental abnormality. Whatever the cause, subsequent abnormal joint loading produces a spectrum of symptoms, from mild swelling to considerable pain and limitations of motion as the involved joints degenerate. A meticulous clinical and radiographic evaluation is required so that the pain-generating articulation(s) can be identi- ﬁed and eliminated. This article reviews common causes of wrist osteoarthritis and their surgical treatment alternatives. (J Hand Surg 2007;32A:725–746. Copyright © 2007 by the American Society for Surgery of the Hand.)

ABSTRACT Background: a Normal Finger Flexion Cascade (FFC) Is Formed by the Fingers of the Hand When the Hand in a Relaxed Position
Int J Physiother. Vol 7(2), 59-68, April (2020) ISSN: 2348 - 8336 ORIGINAL ARTICLE GENDER ORIENTED VARIATIONS IN THE FINGER FLEXION CASCADE IN NORMAL INDIVIDUALS *¹Jibu George Varghese, M.P.T., CMP., COMPT., MCTA. ²Vidhya Venugopal, M.Sc., Ph.D ³V. Srinivasan, M.S., M.Ch. 4G. A. Geetha Hari Priya, M.P.T IJPHY ABSTRACT Background: A normal Finger Flexion Cascade (FFC) is formed by the fingers of the hand when the hand in a relaxed position. Usually, the fingers of the hand assume a flexed position; gender may influence the normative values of the resting hand due to differences in the anatomical structure of hand and frequency of usage of joints of hand in their respective occupation and habitual activities of daily living. Hence the study aims to find the difference in the FFC between men and women in power grip and nonpower grip occupational activities. Methods: A cross-sectional study was conducted in a mixed population of five hundred active individuals aged between 25 and 40 years belonging to various occupations of industrial work and individuals working with software companies. Individuals who fulfilled the inclusion criteria participated in the study. After completing a questionnaire based on occupation, the subjects were grouped into power grip users and nonpower grip users. The range of motion of the joints of all the fingers, namely, metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints of both dominant hand and nondominant hand was measured using universal finger goniometer, and the composite finger flexion was recorded using a geometric ruler. The results were analyzed, and Un-paired T-test was used to compare the FFC between the power grip and the nonpower grip group.

Biomimetic Design and Development of a Prosthetic Hand: Prototype 1.0
15th National Conference on Machines and Mechanisms NaCoMM2011-97 Biomimetic Design and Development of a Prosthetic Hand: Prototype 1.0 Nayan M. Kakoty, Shyamanta M. Hazarika Abstract This paper reports the biomimetic design and development of a prototype of extreme upper limb prosthesis. The motivation for developing a new prosthetic hand is provided by the fact that low functionality and low controllability are the most important reasons why amputees do not use their prosthetic hands. In addi- tion, although multifingered hand prosthesis has appeared in the market, the cost is exorbitantly high and out of reach of common people, which is particularly true for developing countries like India. This paper presents an anthropomor- phic design of a prosthetic hand with 15 degrees of freedom using underactuated mechanism. The bioinspired control is through electromyogram signals based on support vector machine for classification of six grasps involved in 70% of daily living activities. Keywords: Biomimetic, Prosthetic hand, Electromyogram, Grasps 1 Introduction Dexterous artificial hand design and manipulation is an active research topic. A very interesting practical application is the field of upper limb prosthetics. Number of lab- oratory prototypes and commercial versions of upper limb prosthesis have been avail- able. However, electromyogram (EMG) based control is still rudimentary, being lim- ited to a few hand postures; and control is non-intuitive, in the sense that the user is required to learn to associate muscle remnants actions to unrelated posture of the prosthesis. Neuro-bionic hands address some of these issues. However, commercially launched variants (such as i-Limb from Touch Bionics [1]) are exorbitantly priced.

Bilateral Spontaneous Bony Ankylosis of the Elbow Following Burn: a Case Report and Review of the Literature
Case Report Journal of Orthopaedic Case Reports 2018 September-October : 8(5):Page 43-46 Bilateral Spontaneous Bony Ankylosis of the Elbow Following Burn: A Case Report and Review of the Literature Raju Vaishya¹, Amit Kumar Singh¹, Amit Kumar Agarwal¹, Vipul Vijay¹ Learning Point of the Article: The possibility of spontaneous bony fusion in deep burn injuries around the joint should be kept in mind so that effective preventive measures can be taken. Abstract Introduction: Ankylosis of a joint could be intra-articular or extra-articular. Intra-articular ankylosis may be fibrous or bony. Soft tissue contracture and heterotopic ossification area common finding in patients with a deep burn around the joints. Intra-articular bony ankylosis after burn is uncommon, but a possible complication and we present a rare case with bilateral elbow involvement. Case Report: A 35-year-old female presented to us with contracture of both the elbows. She had a history of severe accidental thermal burn involving mainly the front of both the upper limbs 6months back. She developed burn contracture of both elbows. X-rays of both elbows showed bony fusion. Conclusion: Spontaneous bony fusion occurs in various pathologies, some are well known, but some are rare and unusual. Development of soft tissue contracture in deep burn is quite typical, followed by extra-articular ankylosis, but true spontaneous bony fusion can also occur. The possibility of spontaneous bony fusion in deep burn injuries around the joint should be kept in mind by both plastic surgeons and orthopedic surgeons. Keywords: Burn contracture, elbow, bony ankylosis, ossification, joints.

Physical Examination of the Wrist: Useful Provocative Maneuvers
CURRENT CONCEPTS Physical Examination of the Wrist: Useful Provocative Maneuvers William B. Kleinman, MD Chronic wrist pain resulting from partial interosseous ligament injury remains a diagnostic dilemma for many hand and orthopedic surgeons. Overuse of costly diagnostic studies including magnetic resonance imaging, computed tomography scans, and bone scans can be further frustrating to the clinician because of their inconsistent specificity and reliability in these cases. Physical diagnosis is an effective (and underused) means of establishing a working diagnosis of partial ligament injury to the wrist. Carefully performed provocative maneuvers can be used by the clinician to reproduce the precise character of a patient’s problem, reliably establish a working diagnosis, and initiate a plan of treatment. Using precise physical examination techniques, the examiner introduces energy into the wrist in a manner that puts load on specific support ligaments of the carpus, leading to an accurate diagnosis. This article provides a broad spectrum of physical diagnostic tools to help the surgeon develop a working diagnosis of partial wrist ligament injuries in the face of chronic wrist pain and normal x-rays.
