(1/45)
Corticosteroid injections are commonly administered to athletes to relieve symptoms of lateral elbow tendinosis. This report presents a case of almost total rupture of the common extensor origin in a 45 year old female squash player secondary to such a procedure. (+info)
Ocular sports injuries: the current picture.
(2/45)
OBJECTIVES: To determine the recent incidence of eye injury due to sport in Scotland, identify any trend, and establish which sports are responsible for most injury? The type of injury and final visual outcome is also evaluated. METHODS: A prospective observational study of ocular injuries sustained during sport was performed over a one year period. Only patients requiring hospital admission were included. Data were collected on a standardised proforma and entered into a central database. Patients were followed up for at least three months. RESULTS: Of 416 patients admitted because of ocular injury, 52 (12.5%) resulted from playing a sport. Although all racquet sports together accounted for 47.5% of these injuries, football was the single most common sport associated with ocular trauma, being responsible for 32.5% of cases. The most common clinical finding was macroscopic hyphaema occurring in 87.5% of patients. Overall the final visual acuity was 6/6 in 92.5% of patients. CONCLUSIONS: The incidence of eye injury due to sport at 12.5% is lower than previously reported, suggesting a change in the pattern of ocular trauma. Football is the single most common cause of ocular injury from sport in Scotland, but the wearing of protective headgear would be difficult to instigate. The incidence of hyphaema in sport related ocular trauma (87.5%) is almost double that of all ocular injury (47.8%), so the potential for serious visual loss as the result of a sports injury should not be underrated. Ophthalmologists have a role in protecting this young population at risk by actively encouraging the design and use of protective eyewear. (+info)

Two patients are described with delayed presentation of a ruptured tendo Achilles, each exhibiting signs of sural nerve dysfunction. Recovery occurred in each case after operative repair. (+info)
Are squash players protecting their eyes?
(4/45)
OBJECTIVE: To determine factors associated with adult squash players' protective eyewear behaviours. METHODS: A survey of 303 players (aged >or =18 years) was conducted at three squash venues in Melbourne, Australia over a three week period in June 2000 to obtain information about protective eyewear use. RESULTS: Of 303 participants the response rate was 98.1%; 66.1% were males, with a mean age of 40.5 years. The majority (68.4%) had played squash for 10 years or more. Although 18.8% of players reported using protective eyewear, only 8.9% reported wearing approved eyewear. Both age group (p<0.05) and years of squash experience (p<0.01) were significantly associated with any eyewear use. The two main influences were personal experience of eye injuries (50.0%) and knowledge of eye injury risk (33.9%). A commonly reported barrier was restriction of vision (34.2%). CONCLUSION: These findings demonstrate a low prevalence of voluntary use of appropriate protective eyewear. Future prevention strategies incorporating education campaigns should focus on increasing players' knowledge of risks. The barriers to use and misconceptions about which types of eyewear is most protective need to be addressed as a priority. (+info)
Have the attitudes of Australian squash players towards protective eyewear changed over the past decade?
(5/45)
OBJECTIVE: To assess indicative trends in the use of protective eyewear by Australian squash players and their attitudes towards its use since 1989. METHODS: Data were extracted from three Australian surveys of squash players conducted in 1989, 1995, and 2000. Responses to directly similar attitudinal questions relating to protective eyewear use from each survey were compared. The proportion of players giving each response was calculated for each survey, along with 95% confidence intervals for the differences between the 2000 survey and those from the earlier surveys. RESULTS: Self reported use of protective eyewear ranged from 10.0% in 1989, to 8.6% in 1995, and 18.8% in 2000. However, only 8.9% of the players surveyed in 2000 actually wore appropriate standards approved/polycarbonate lens eyewear. This can be compared with 8.0% and 2.0% of players who reported wearing appropriate polycarbonate lens eyewear in the 1989 and 1995 surveys respectively. Compared with the 1995 survey, significantly more players in 2000 believed that more players should wear protective eyewear (95% confidence interval (CI) for difference 1 to 18). A significantly higher proportion of players also supported the compulsory use of protective eyewear by juniors in 2000 than in both 1989 (95% CI for difference 6 to 24) and 1995 (95% CI for difference 5 to 22). No other attitudes had significantly changed over the decade. CONCLUSION: These data suggest that self reported use of protective eyewear has probably increased over the past decade. However, many players report wearing inappropriate eyewear. A transition from positive attitudes to appropriate eyewear behaviours is required before mandatory protective eyewear use can be effectively introduced. (+info)
Analysis of the characteristics of competitive badminton.
(6/45)
OBJECTIVE: To describe the characteristics of badminton in order to determine the energy requirements, temporal structure, and movements in the game that indicate performance level. To use the findings to plan training with greater precision. METHODS: Eleven badminton players (mean (SD) age 21.8 (3.26) years) with international experience from four different countries (France, Italy, Spain, and Portugal) were studied. Two of the Spanish players were monitored in several matches, giving a total of 14 samples, all during the 1999 Spanish International Tournament. Blood lactate concentration was measured with a reflective photometer. Maximum and average heart rates were recorded with a heart rate monitor. Temporal structure and actions during the matches were determined from video recordings. All variables were measured during and after the game and later analysed using a descriptive study. RESULTS: The results confirmed the high demands of the sport, with a maximum heart rate of 190.5 beats/min and an average of 173.5 beats/min during matches over 28 minutes long and performance intervals of 6.4 seconds and rest time of 12.9 seconds between exchanges. CONCLUSIONS: The results suggest that badminton is characterised by repetitive efforts of alactic nature and great intensity which are continuously performed throughout the match. An awareness of these characteristics, together with data on the correlations between certain actions such as unforced errors and winning shots and the final result of the match, will aid in more appropriate planning and monitoring of specific training.

Validation of a field test for the non-invasive determination of badminton specific aerobic performance.
(7/45)
AIM: To develop a badminton specific test to determine on court aerobic and anaerobic performance. METHOD: The test was evaluated by using a lactate steady state test. Seventeen male competitive badminton players (mean (SD) age 26 (8) years, weight 74 (10) kg, height 179 (7) cm) performed an incremental field test on the badminton court to assess the heart rate turn point (HRTP) and the individual physical working capacity (PWC(i)) at 90% of measured maximal heart rate (HR(max)). All subjects performed a 20 minute steady state test at a workload just below the PWC(i). RESULTS: Significant correlations (p<0.05) for Pearson's product moment coefficient were found between the two methods for HR (r = 0.78) and velocity (r = 0.93). The HR at the PWC(i) (176 (5.5) beats/min) was significantly lower than the HRTP (179 (5.5) beats/min), but no significant difference was found for velocity (1.44 (0.3) m/s, 1.38 (0.4) m/s). The constant exercise test showed steady state conditions for both HR (175 (9) beats/min) and blood lactate concentration (3.1 (1.2) mmol/l). CONCLUSION: The data indicate that a valid determination of specific aerobic and anaerobic exercise performance for the sport of badminton is possible without HRTP determination. (+info)
Lacrosse stick entrapment injury to the thumb.
(8/45)
A case of injury to the left thumb following an errant stick check, and subsequent entrapment of the digit in the open sidewall of a lacrosse stick, is presented. A circumferential laceration, severe swelling, and bruising to the proximal phalanx resulted. This case report emphasises the need to limit the dimensions of openings in the sidewalls of lacrosse sticks to prevent the occurrence of this and other preventable injuries. (+info)
