. . . the plaintiff gave up the heavier manual type of work he was performing prior to the accident and has since successfully started his own business, where he works as an earthmoving contractor and manages to use the heavy equipment involved in this business at the same time as accommodating the ongoing impairment of his right arm. However, notwithstanding his success in establishing his own business, the plaintiff describes the following consequences, which he asserts are serious to him:
• Both in his business and in his domestic environment, pain prevents him from digging holes which require twisting and powerful movement of the right arm. However, the plaintiff agrees that from time to time when he has to, he can shovel out dirt at a worksite for a couple of minutes.
• He is unable to fully extend the elbow of his right arm or, with the arm extended as much as he can, turn his palm fully up or down. These restrictions were demonstrated in Court and are consistent with the medical evidence confirming a fixed flexion deformity of his right elbow and a loss of supination and pronation in the forearm. The most recent medical opinion is that obtained from Mr Huffam, an examining orthopaedic surgeon who measured the plaintiff's movements in September this year, noting that the plaintiff '... had moderate limitation of movement of the elbow joint with 40 degree loss of flexion and then flexion to 120 degrees. Twisting movements of the forearm, pronation and supination were limited to 40° pronation and 40° supination, that is about half the normal range of movement. These movements were measured with a goniometer. He had a moderate limitation of movement of the right wrist. Dorsiflexion 40°. Palmar flexion 60°. Radial deviation 15°. Ulna deviation 30°. He had a full range of movement of the finger joints. It was noted that the skin of the right hand was quite solid and thickened, indicating that he is using his hand for manual work. Muscle power of flexion and extension of the elbow, pronation and supination of the forearm and flexion and extension of the wrist and fingers all appear to be undiminished. ... Mr Dwyer has made quite a good, although not complete recovery from his injury'.
• In Court, the plaintiff demonstrated that he is unable to draw his right forearm back up against his bicep to the same extent as he can with his left forearm. The difference is apparent and, according to the plaintiff, it causes him pain to try and push the right forearm further.
• There is a loss of strength and muscle wastage in the plaintiff's right arm. The most recent measurement of the plaintiff's grip strength was undertaken by Mr Henderson in mid 2003, confirming a significant loss of strength in the plaintiff's right hand. So far as muscle wasting is concerned, this provides objective proof of damage and under-use of the dominant right limb, and in September this year Mr Huffam noted: 'There was some relative wasting of the right arm compared to the left. Circumferences of the right upper arm 35cm, left 36.5cm. Right forearm 30cm, left 32cm.'.
• There is numbness on either side of both scars. Mr Huffam, in his report, refers to 'an area of diminished sensation posterior to the scar over the extensor compartment of the arm'. However, Mr Henderson, in his earlier report, refers to '... a large elongated triangular area of sensory deficit of the posterior anti-brachial cutaneous nerve branch of the radial nerve. This area extends posteriorly for some 5cm from the scar, below the 10cm-15cm junction; and about 4cm proximal above this site of change of direction of the scar'.
• Since the accident, the pain and discomfort experienced in his right arm has caused him to give up activities such as motorbike riding at weekends and playing social games of golf as he previously did a dozen or more times a year. Although the plaintiff has ridden a pushbike 'on the odd occasion' since the accident, he says he is now unable to undertake this activity with his partner and her children without pain. He also finds activities such as personal toileting and reaching with his arm extended to a position behind him awkward and painful. Generally speaking, all of the medical evidence, particularly the most recent medical opinion, supports the plaintiff's complaints concerning the level of restriction the impairment of his right arm imposes on his social, recreational and domestic activities.
• The plaintiff describes the frequency and level of pain in his right arm in his most recent affidavit by saying: 'I continue to have daily pain in my right arm. I wake in the morning with an aching pain in the arm which lasts for approximately 1 hour. By the time I get to work I am generally pain free. However the pain tends to recur in the day due to the physical nature of the work I do. I am right handed and have always favoured the use of my right arm. Activities such as lifting ramps from the bobcat, driving the truck and digging cause an aggravation of my right arm pain. By the end of most working days I experience an aching in my right arm. Additionally I experience short intermittent periods of sharp pain in my right elbow on most days. ... I no longer see any treating doctors or take any medication for my right arm. The doctors have told me that there is nothing more they can do for me'.
• There is a risk of the development of osteoarthritis in the right elbow. Both the hospital report and Mr Davie, in his report in 2004, allude to this possibility.
• The impairment of the plaintiff's right arm precludes him from performing the heavy manual type of work he was doing prior to the accident. The medical evidence supports this view, but also points to the fact that the plaintiff has been able to return to full-time and active employment as an earthmoving contractor. The long segment of video film showing the plaintiff working at various construction sites in October last year confirms that, notwithstanding the restrictions imposed by the permanent impairment of his dominant arm, the plaintiff appears to function well and to use his right arm effectively.
