1. X-ray, cine and video recordings were made of the movement of radio-opaque markers injected into the musculo-tendinous junctions of biceps brachii muscle. 2. In strong isometric contractions, the distal tendon of the long head of biceps lengthened by about 2% of its estimated rest length. 3. During voluntary isotonic elbow flexion-extension movements at frequencies up to 5.5 Hz there was no detectable phase shift between intramuscular and joint displacements. 4. In the fastest alternating movements (5.5-6.7 Hz) small phase advances developed in the muscle. 5. We conclude that human tendons do stretch during muscle contraction, but not enough to cause intramuscular phase reversals in rapid unloaded movements. This in turn means that muscle spindles shorten and lengthen virtually in phase with joint movements under most conditions.

Pring DJ, Amis AA, Coombs RR, 1985, The mechanical properties of human flexor tendons in relation to artificial tendons., J Hand Surg Br, Vol: 10, Pages: 331-336, ISSN: 0266-7681

The continuation of an unacceptable failure rate with tendon repair or grafting procedures, largely due to adhesions, suggested that an artificial flexor tendon could be an attractive alternative. A literature search found no published data of the mechanical properties of fresh human finger flexor tendons, so a study of the strength and extensibility of 153 tendons was carried out. The bone insertion strength of twenty middle finger tendons was also examined. The results showed that an artificial tendon should have a strength of approximately 1500N, and that it should extend 13% at that load, an elongation of 26mm for a tendon 200mm long. The insertion strength was less than a half of the tendon strength. This data will allow an artificial flexor tendon to be designed with sufficient strength and the correct elastic properties to allow its function to integrate reliably with natural tendons in adjacent fingers.

Amis AA, Miller JH, 1984, DESIGN, DEVELOPMENT, AND CLINICAL TRAIL OF A MODULAR ELBOW REPLACEMENT INCORPORATING CEMENT-FREE FIXATION., Pages: 121-126

This paper describes the design process leading to a total elbow replacement with components which have an accurate anatomical shape and require minimal bone resection. This allows a 'modular' approach to elbow reconstruction, i. e. radial head replacement alone; humeral hemiarthroplasty; humero-radial or ulnar replacement; or total (three component) reconstruction. This approach means that the surgeon may choose to replace only the damaged joint surfaces, rather than being committed to total replacement. The parallel development of instruments for accurate bone forming is also described, allowing firm and precise fixation of prosthetic components without bone cement, a necessity for interlocking bone ingrowth to occur without extended immobilization. A clinical trial of these components, in more than fifty patients for periods up to five years, is reviewed.
