The understanding of their physiology and pathology is gaining importance as advances in regenerative medicine are being made today. So far, very few studies were conducted to extend the knowledge about pathology, healing response and management of tendon lesions. In this paper we summarise actual knowledge on structure, process of healing and ageing of the tendons. The structure of tendon is optimised for the best performance of the tissue. Despite the simplicity of the healing response, nume- rous studies showed that the problems with full recovery are common and much more significant than we thought; that is why we discussed the issue of immo- bilisation and mechanical stimulation during healing process. The phenomenon of tendons’ ageing is poorly understood. Although it seems to be a natural and painless process, it is completely different from degeneration in tendinopathy.

    Module Two: Anatomy of the Athlete INTRODUCTION The Level One course provided you with basic information about the skeletal and muscular systems of the body. This module studies these systems in more depth, applies this knowledge to the analysis of human movement, and looks at the application of analysis results to the development of conditioning programmes for athletes. Upon completion of this module, you will be able to: EXPLAIN THE STRUCTURE AND FUNCTIONS OF THE SKELETAL SYSTEM UNDERSTAND THE STRUCTURE OF JOINTS AND THE MOVEMENTS POSSIBLE AT SYNOVIAL JOINTS EXPLAIN THE STRUCTURE AND FUNCTIONS OF THE MUSCULAR SYSTEM EXPLAIN MUSCLE ACTION IN THE HUMAN BODY APPLY YOUR KNOWLEDGE OF THE SKELETAL AND MUSCULAR SYSTEMS TO ANALYSE MUSCLE ACTION EXPLAIN THE STRUCTURE AND FUNCTIONS OF THE SKELETAL SYSTEM THE SKELETAL SYSTEM The framework of the human body is made up of just over 200 bones, which vary considerably in size and shape. Bones are often thought of as dry, inert structures, similar to a bone which has been dug up in the garden by the neighbour’s dog! However, bone is not a dead structure. It is made up of living bone tissue, which is a type of connective tissue, the hardest of all connective tissues found in the body. FUNCTIONS OF THE SKELETON The skeleton has five important functions in the body: 1. Protection The bones protect internal organs by forming strong protective enclosures, e.g. skull, ribs, spine. 2. Support The skeleton gives rigidity to the body. Without the support of the skeleton, we would be shapeless lumps. 3.

  • A Huge Giant Cell Tumour of the Extensor Tendon Sheath of the Foot: a Case Report and Literature Review
    Case report East African Orthopaedic Journal A HUGE GIANT CELL TUMOUR OF THE EXTENSOR TENDON SHEATH OF THE FOOT: A CASE REPORT AND LITERATURE REVIEW A. Younus, FC Orthopedics (SA), T. Joseph, MBChB (SA), Helen Joseph Hospital, Johannesburg, South Africa and A. Kelly, FC Neurosurgery (SA), Dr George Mukhari Academic Hospital, Pretoria, South Africa Correspondence to: Dr Adrian Kelly, P.O. Box Medunsa, Pretoria, South Africa. Email: adriankelly1000@ yahoo.co.uk ABSTRACT Giant cell tumours have a predilection for the hand, where after ganglion cysts, they are the most frequent tumour type. Only 3-5% of giant cell tumours occur in the foot, and even here they tend to occur in the forefoot, with hindfoot giant cell tumours being a rarity. While relatively common overall, their exact nature, as to whether they are truly neoplastic or simply inflammatory, is a subject of significant controversy. They are benign slow growing lesions, best treated with gross total excision under magnification. Despite their subcutaneous nature, they can become markedly infiltrative, and unless completely excised exhibit recurrence rates of between 14% and 44%. Factors predictive of recurrence include pressure erosion on X-ray imaging, interphalangeal joint location, concomitant degenerative joint disease, and incomplete excision. We present an adult female patient who presented to our unit with a giant cell tumour extending over the dorsum and medial side of her foot of an alarming size. While the lesion was largely asymptomatic, she was offered surgery for functional reasons. Through the creation of a local flap over the tumour, and using magnification, we were able to achieve a gross total excision.
