The work described in this thesis was carried out by the author to address perceived deficiencies in the knowledge of wrist anatomy, imaging and arthroscopy that limited the surgical treatment of wrist disorders. The thesis encompasses studies of normal anatomy, imaging of the abnormal wrist and the development of wrist arthroscopy. At the commencement of this work problem areas identified, which were addressed, included (i) the morphology and kinematics of the normal wrist, (ii) imaging of scaphoid deformity and the clinical application of fluoroscopy in the management of the wrist disorders, and (iii) surgery of the wrist, which was usually performed as an open procedure, and the clinical application of wrist arthroscopy, which was in its first decade of development. To address these deficiencies, a radiological study was undertaken to determine how the morphology of the lunate affected the kinematics of the scaphoid. Lunate morphology was demonstrated to be associated with scaphoid kinematics. The result of this finding is that it is now possible to predict scaphoid kinematics because lunate type can be determined from plain radiographs. An anatomical study of the triquetro-hamate joint was undertaken to determine the morphology of this joint and whether it is related to the lunate morphology. Two types of triquetro-hamate joint were identified but these were not associated with the morphology of the lunate. One type had a helicoidal configuration and the other was relatively flat. These morphological differences are likely to have implications for wrist kinematics. To image deformity of the scaphoid, a standardised method of longitudinal computed tomography was developed. An inter-observer reliability study was undertaken to compare the previously reported intra-scaphoid angle to newly developed methods of assessing the humpback deformity. The height-to-length ratio and dorsal cortical angle were found to be more reliable than the intra-scaphoid angle. The concepts of partial volume averaging for the assessment of scaphoid fracture union and pre-operative templating of correction of scaphoid deformity were described. The role of arthroscopy was investigated in a number of clinical conditions. Patients withKienböck’s disease were assessed to determine whether characteristic patterns of articular changes could be identified at arthroscopy. Based on the findings, a classification of these arthroscopic findings was developed and used to direct future treatment. A study of arthroscopically assisted reduction of distal radius fractures was undertaken, which included development of new arthroscopically assisted and mini-open reduction and fixation techniques. Post-operative articular deformity was found to be associated with an increased incidence of pain. Arthroscopic debridement for scaphotrapezotrapezoidal joint arthritis was demonstrated to be a safe and effective treatment, with a lower complication and re-operation rate than with previously reported open procedures. New arthroscopic methods of capsular release of the wrist, arthroscopically assisted drilling of intra-osseous ganglion of the lunate and arthroscopic debridement of the ulnar styloid were developed. Fluoroscopy was valuable in pre-operative assessment as well as the intra-operative management using these new techniques. In summary, the work described in this thesis increases the knowledge of the normal and abnormal wrist morphology and advances the role of arthroscopy in the treatment of wrist conditions. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1321390 / Thesis (Ph.D.) - University of Adelaide, School of Medicine, 2008

Wrist orthoses are the most common upper limb orthoses, being used by thousands of individuals each year to stabilize, immobilize, or support the wrist joint. Wrist orthoses achieve their function by altering the stiffness of the wrist joint (Figure 1-1). However, there is no quantitative understanding of how wrist orthoses affect wrist stiffness, and consequently, wrist orthosis development often relies on feel, intuition, or empirical heuristics rather than a methodical, quantitative approach. Because wrist movement control is dominated by wrist joint stiffness (Charles and Hogan 2011) a quantitative understanding of how wrist orthoses alter the stiffness of the wrist is imperative to the development of improved wrist orthoses with properties tailorable to the needs of the thousands of individuals who use them. In order to begin bridging this gap, our research characterized the stiffness of four common groups of wrist orthosis in two degrees of freedom: flexion-extension (FE) and radioulnar deviation (RUD) which are the degrees of motion most affected by wrist orthoses. We used a wrist robot to measure how twelve orthoses altered the passive wrist stiffness of twenty healthy subjects (three orthoses and five subjects per orthosis group). To perform these measurements we designed a unique wrist-mounting fixture (Figure 3-2) which allows the wrist robot to manipulate the hand inside an orthosis without interfering with orthosis motion (more accurately simulating the actual hand-orthosis interaction). Our results showed that (1) three out of four orthosis groups significantly altered the stiffness of the wrist joint, (2) orthoses in the same group are not generally significantly different than one another, and (3) there are important differences in stiffness between different orthosis groups. An interesting implication of our research is the result that in many cases orthoses with volar stays may be interchanged with orthoses with both volar and dorsal stays without significant changes in orthosis performance (Table 4-2). We anticipate this work will prove fruitful toward the future study of wrist orthoses' effects on wrist movement behavior and the future improvement of wrist orthosis design.

Thesis (M.Tech.:Chiropractic)- Dept. of Chiropractic, Durban Institute of Technology, 2006. xiii, 84 leaves, Annexures A-J. / Many studies have been done investigating the role that muscle imbalances play in causing injury to the body, for example the knee and the shoulder. It has been found that keeping muscle balances around a joint play an important role in protecting the soft tissue structures. There is a need to further investigate the effect of muscle imbalances in the upper limb. Additionally, according to the literature, as yet no effective treatment protocol or a specific cause has been found for lateral epicondylitis making it a troubling condition for practitioners to treat and a disabling condition for patients to live with. Therefore, this research aimed at investigating whether muscle imbalances are associated with the aetiology of lateral epicondylitis. If an association was found, people involved in predisposing activities could improve the imbalance to avoid the condition, thereby minimizing time spent away from work and sport. Also, a more effective and efficient management protocol for the painful condition could be attained. The objectives of this study included: 1) assessing the peak torque (using the Cybex Orthotron II) and muscle activity (using surface electromyography) of the wrist flexor and extensor muscle groups of asymptomatic subjects; 2) assessing the peak torque (using the Cybex Orthotron II) and muscle activity (using surface electromyography) of the wrist flexor and extensor muscle groups of symptomatic subjects and 3) to integrate this information, compare the two groups and subgroups and statistically analyse the difference between them.
