A 35-year-old basketball player suffered a serious double head injury during a match. An acute left temporal epidural haematoma, which necessitated surgical drainage, developed. The exceptional circumstances of the trauma are discussed and the literature concerning basketball-related injuries is reviewed.
Although the literature records instances of acute epidural haematoma and acute subdural haematoma related to playing basketball, there has not been a report of chronic subdural haematoma as a basketball injury. With the burgeoning interest in this sport in the United Kingdom and Europe, the possibility of this particular neurotrauma increases. Such an injury, along with the diagnosis and management of this often insidious lesion, is documented in this case report.
Injuries in basketball are usually to the ankles and knees. Dislocation of the hip is usually associated with severe trauma--for example, road traffic accidents. A case is reported here in which a 22 year old club basketball player slipped on landing from a jump shot, forcing him into a side splits position from which he sustained a posterior dislocation of the hip resulting in a sciatic nerve palsy.
OBJECTIVE: To determine the acute injury profile in each of six sports and compare the injury rates between the sports. DESIGN: Analysis of national sports injury insurance registry data. SETTING: Finland during 1987-91. SUBJECTS: 621,691 person years of exposure among participants in soccer, ice hockey, volleyball, basketball, judo, or karate. MAIN OUTCOME MEASURES: Acute sports injuries requiring medical treatment and reported to the insurance company on structured forms by the patients and their doctors. RESULTS: 54,186 sports injuries were recorded. Injury rates were low in athletes aged under 15, while 20-24 year olds had the highest rates. Differences in injury rates between the sports were minor in this adult age group. Overall injury rates were higher in sports entailing more frequent and powerful body contact. Each sport had a specific injury profile. Fractures and dental injuries were most common in ice hockey and karate and least frequent in volleyball. Knee injuries were the most common cause of permanent disability. CONCLUSIONS: Based on the defined injury profiles in the different sports it is recommended that sports specific preventive measures should be employed to decrease the number of violent contacts between athletes, including improved game rules supported by careful refereeing. To prevent dental injuries the wearing of mouth guards should be encouraged, especially in ice hockey, karate, and basketball.
Recent publications have reported differences in the incidence, rate, risk, and type of sports injury among men and women. We undertook a prospective study to determine the incidence of injury among high school basketball players and to examine the differences in injury type, incidence, rate, and risk between male and female athletes. During a single basketball season, an injury survey of girls' varsity teams at 100 class 4A and 5A high schools in Texas was conducted. These data were previously reported. We surveyed the same 100 high schools during a subsequent season to gather injury data from the boys' varsity teams. The athletic trainer collected data on each reportable injury and reported the data weekly to the University Interscholastic League. A reportable injury was defined as one that occurred during a practice or a game, resulted in missed practice or game time, required physician consultation, or involved the head or the face. The boys' and girls' data were compared and statistically analyzed. The rate of injury was 0.56 among the boys and 0.49 among the girls. The risk of injury per hour of exposure was not significantly different between the two groups. In both groups, the most common injuries were sprains, and the most commonly injured area was the ankle, followed by the knee. Female athletes had a significantly higher rate of knee injuries including a 3.79 times greater risk of anterior cruciate ligament injuries. For both sexes, the risk of injury during a game was significantly higher than during practice.
This retrospective study compares the results of different therapies for fibular ligament rupture in a homogenous group of professional athletes. The endpoint "competitive sports" was an outcome consideration. Subjects were examined by means of a standardized questionnaire and a structured interview. One hundred and seventy-nine of the questionnaires were completed and returned for evaluation. All of the basketball players with severe ankle sprain (supination trauma with swelling, pain, and inability to bear stress) were included. Those players with fractures of the foot, pronation trauma, or additional distal fibula or tibia fractures were excluded from this study. Of the 179 basketball players 160 (89%) had suffered severe ankle sprain. The treatment was divided into three groups: primary surgery (N = 35), plaster cast (N = 39), and functional treatment (N = 89). While simple ligament injuries (Grade I and II) were mostly treated functionally, complex ligament injuries (Grade III) were usually operated on. A total of 119 (74%) of the players reported no further pain. For pain reduction surgical and functional treatments showed advantages over plaster treatment. In the surgical group 63% of the players judged their regained stability to be equivalent to that of their healthy leg. Only 50% of the players in the plaster and functional groups believed their ankle joints to have regained the same stability as before their injuries. Despite the achievement of good results through surgery, there were clear differences in the players' assessments of their performance in competitive sports. Most subjects (92%) did not have any problems in everyday life regardless of which kind of therapy had been chosen.(ABSTRACT TRUNCATED AT 250 WORDS)
PURPOSE: The purpose of this study was to utilize three-dimensional kinematic (motion) analysis to determine whether gender differences existed in knee valgus kinematics in high school basketball athletes when performing a landing maneuver. The hypothesis of this study was that female athletes would demonstrate greater valgus knee motion (ligament dominance) and greater side-to-side (leg dominance) differences in valgus knee angle at landing. These differences in valgus knee motion may be indicative of decreased dynamic knee joint control in female athletes. METHODS: Eighty-one high school basketball players, 47 female and 34 male, volunteered to participate in this study. Valgus knee motion and varus-valgus angles during a drop vertical jump (DVJ) were calculated for each subject. The DVJ maneuver consisted of dropping off of a box, landing and immediately performing a maximum vertical jump. The first landing phase was used for the analysis. RESULTS: Female athletes landed with greater total valgus knee motion and a greater maximum valgus knee angle than male athletes. Female athletes had significant differences between their dominant and nondominant side in maximum valgus knee angle. CONCLUSION: The absence of dynamic knee joint stability may be responsible for increased rates of knee injury in females but is not normally measured in athletes before participation. No method for accurate and practical screening and identification of athletes at increased risk of ACL injury is currently available to target those individuals that would benefit from neuromuscular training before sports participation. Prevention of female ACL injury from five times to equal the rate of males would allow tens of thousands of young females to avoid the potentially devastating effects of ACL injury on their athletic careers.
Dissection of the vertebral artery represents a significant potential cause of strokes among young and middle-aged people. We present a case of dissection of the vertebral artery observed at the forensic autopsy of a professional basketball player who was suddenly taken ill during a practice game and died seven days after the event. A medico-legal autopsy was performed in order to establish an essential causal relationship between arterial dissection and basketball activity. No preceding trauma possibly contributing to the dissection was discovered. The histology of the arterial wall did not show specific alterations in the adventitia, the muscular layer, or the intima. In addition, the toxicological examination excluded any effects of drugs of abuse. We describe macroscopic and microscopic findings in the autopsy, and discuss possible mechanisms of the arterial rupture as well as the autopsy procedure in similar cases.
We present two rare cases of volar and dorsal fractures of the middle phalanx at the proximal interphalangeal joint (PIPJ). The first case was a 16-year-old girl. She hurt her middle finger while playing basketball. A lateral radiograph revealed volar and dorsal fractures of the middle phalanx. She underwent external immobilization of the PIPJ in 30 degrees of flexion with a splint for 3 weeks. The fractures healed 7 weeks after the injury with neither tenderness nor limitation of range of motion. The second case was a 16-year-old boy. He injured his index finger while playing basketball, and underwent immobilization of the PIPJ for 3 weeks. At 10 weeks after the injury, the dorsal fracture was almost healed, but the displacement of the volar fragment had worsened. At a 3-year follow-up, the dorsal fragment was healed, but the volar fragment remained in a site of nonunion. However, there was neither residual deformity nor restriction of movement.
We measured vertical jump, anaerobic power, and shooting accuracy in 18 Division I women basketball players (age 18-22 years) 6 hours following a morning strength training routine called a lift day (LD) and on a control day in which no strength training was performed. Subjects had been strength trained for 4 weeks prior to testing. The strength training session on lift day was a full-body workout and included 7 exercises performed in 3-6 sets at loads ranging from a 5 to 12 repetition maximum (RM). There were no significant differences in jump height with 2 legs (49.5 +/- 4.8 cm and 49.0 +/- 4.8 cm, LD and control, respectively), relative mean power output over 30 seconds on a Wingate bicycle test (6.4 +/- 0.8 W.kg(-1) and 6.6 +/- 0.7 W.kg(-1), LD and control, respectively), or shooting accuracy over 60 seconds (21.5 +/- 3.8 points/min and 21.3 +/- 4.1 points/min, LD and control, respectively). These data suggest that in collegiate women basketball players, a previous bout of strength training has no negative effect on vertical jump height, anaerobic power, or shooting accuracy.
This study was conducted to monitor the training patterns throughout a basketball season in order to determine if a relationship exists between the physical stress of practice and the occurrence of injuries and illnesses in NCAA Division III athletes. Subjects consisted of college women (n = 12) ranging in age from 18 to 22 years. A certified athletic trainer distributed a questionnaire following each practice, including 2 weeks of preseason, documenting the presence of injury, illness, or both, relative to the intensity and duration of practice. Training load, training monotony, and training strain were computed using the session rate of perceived exertion scale method. An increase in injuries occurred during times of increased training loads, particularly during the first 2 weeks of formal practice, and immediately subsequent to the holidays. The temporal relationship between training load and injury suggests a causative link (p < 0.01; r = 0.675). The present data suggest that the periodization pattern of basketball training may be linked to the likelihood of illness/injury.
We applied the matching equation to evaluate the allocation of two- and three-point shots by male and female college basketball players from a large Division 1 university. The matching law predicts that the proportion of shots taken from three-point range should match the proportional reinforcement rate produced by such shots. Thus, we compared the proportion of three-point shots taken relative to all shots to the proportion of three-point shots scored relative to all shots scored. However, the matching equation was adjusted to account for the greater reinforcer magnitude of the three-point basket (i.e., 1.5 times greater than the two-point basket reinforcer magnitude). For players with substantial playing time, results showed that the overall distribution of two- and three-point shots was predicted by the matching equation. Game-by-game shot distribution was variable, but the cumulative proportion of shots taken from three-point range as the season progressed was predicted almost perfectly on a player-by-player basis for both male and female basketball players.
Previous research has applied the behavioral momentum metaphor to men's college basketball. In the current investigation, the relative rate of reinforcement prior to and following adversities (e.g., turnovers, fouls) and periods of time-out were examined in a subset of women's college basketball games.
OBJECTIVE: Metatarsal stress fractures are common and represent debilitating and potentially season-ending injuries for basketball players. Bone marrow edema is readily visualized on MRI and can be a sign of stress changes. Twenty-six asymptomatic male National Collegiate Athletic Association basketball players were imaged before the 2003-2004 season and 14 players were reimaged after the conclusion of the season with a screening study of long- and short-axis fat-suppressed T2-weighted images (TR/effective TE, 3,500/56) to identify bone marrow edema in the metatarsals. CONCLUSION: Six (12%) of 52 feet showed a signal indicating bone marrow edema in the metatarsals. MRI depicts bone marrow edema in the feet before a fracture becomes evident. Identification of this edema may reveal stress changes, allowing early treatment and prevention of debilitating stress fractures.
This study examined the validity of the Sport Orientation Questionnaire (Competitiveness: 13 items, Win Orientation: 6 items, and Goal Orientation: 6 items) in a sample of 195 wheelchair basketball athletes from the USA. Following evidence for sample-specific validity, the measurement model that underlies the questionnaire was examined. A short-form with 15 items for three factors of Competitiveness (7 items), Win Orientation (5 items) and Goal Orientation (3 items) fit the data (X2/df ratio=2.21, NNFI=.892, CFI=.991, RCFI=.935, SRMR=.058, RMSEA=.071). To evaluate the findings further, we cross-validated the short-form by sex. Structural equation modeling indicated there were similar measurement properties and factor structures for the men and women, indicating similar conceptualization of sport orientations. Meaningful comparisons across sex may be undertaken, since both men and women who are wheelchair basketball athletes perceive the three short-form SOQ factors similarly.
Strain in basketball competition can be structured temporally into three psychologically meaningful phases: a beginning, main, and endphase of each half-time. The relevance of these phases for the diagnosis of an individual psychological crisis during the competition is discussed. Empirical evidence is based on the results of a study conducted on 28 basketball experts, who were asked to assess the components of the Bayesian likelihood ratio (diagnosticity) for each phase, thereby evaluating the crisis-relevance of that phase. Analysis of variance shows the significant influences of the hypothesized crisis-noncrisis character, half-time (first-second) and phase (beginning, main, end) on the (considerable) diagnostic relevance of the time-phases. The authors briefly discuss the meaning of the present results.
The present study compared performance in basketball as measured by a variety of performance measures to 15 men and 13 women players' moods as measured by the Profile of Mood States. The results suggested that the basketball players' performance was disrupted by a negative mood.
The aim of this study was to examine differences between experts and novices in a number of perceptual abilities. Three groups of elite athletes, 44 members of Greek national teams in basketball (n = 12), volleyball (n = 13), and water-polo (n = 19) were selected. Two groups of physical education students (ns = 18 and 21) were novices. The measured abilities were selected as the most important for an elite athlete by expert coaches in the three sports. The four most frequently selected abilities for each sport, according to the coaches' opinions, were finally assessed. Analysis showed that differences were fewer than expected. Basketball experts were better on prediction and selective attention. Volleyball experts performed better on perceptual speed, focused attention, prediction, and estimation of speed and direction of a moving object. Water-polo players had significantly better scores than the novices on decision-making, visual reaction time, and spatial orientation. It seems that the nature of each sport strongly influences the way perceptual abilities differentiate elite athletes from novices.
