Objective: Present a clinical case detailing the assessment and management of a collegiate baseball player suffering from symptomatic laxity of the proximal tibiofibular joint. Background: Injuries to the proximal tibiofibular joint are rare, and generally accompanied by some form of trauma. Typically, dislocations of the proximal tibiofibular joint occur in an anterior direction, and require reduction and possible fixation as a first course of treatment. Treatment: A 20-year-old collegiate baseball player reported to the athletic training clinic complaining of idiopathic lateral right knee pain. The patient could not recall a mechanism, but recalled an insidious onset of pain that had begun two months prior to reporting to the athletic training staff. There has been some documentation of patients presenting with congenitally lax proximal tibiofibular ligaments, but at this time there is no demographic information on this patient population. Uniqueness: Most cases of proximal tibiofibular laxity occur as a result of trauma. In this patient’s case, there was no specific mechanism of injury or site morbidity to suggest an injury had occurred. Additionally, the patient was able to develop dynamic, and functional stability before regaining static stability. Conclusion: Anatomical abnormalities offer clinicians a unique opportunity to explore multiple levels of problem solving and patient assessment. Further research needs to be conducted to provide demographic data and treatment options for patients suffering from proximal tibiofibular joint laxity.

Background: Bat swing and grip type may contribute to hook of hamate fractures in baseball players. Purpose: To compare the effects of swing type and batting grip on the pressure and rate of pressure development over the hook of hamate in collegiate baseball players. Study Design: Descriptive laboratory study. Level of evidence, 3. Methods: This was an experimental quasi-randomized study of bat grip and swing differences in National Collegiate Athletic Association Division I baseball players (N = 14; age, 19.6 ± 1.1 years [mean ± SD]). All participants performed swings under 6 combinations: 3 grip types (all fingers on the bat shaft [AO], one finger off the bat shaft [OF], and choked up [CU]) and 2 swing types (full swing and check swing). Peak pressure and rate of pressure generation over the area of the hamate were assessed using a pressure sensor fitted to the palm of the bare hand over the area of the hamate. Wrist angular velocities and excursions of radial ulnar deviation were obtained using 3-dimensional motion analysis. Results: The OF–check swing combination produced the highest peak pressure over the hamate (3.72 ± 2.64 kg/cm2) versus the AO–full swing (1.36 ± 0.73 kg/cm2), OF–full swing (1.68 ± 1.17 kg/cm2), and CU–full swing (1.18 ± 0.96 kg/cm2; P < .05 for all). There was a significant effect of condition on rate of pressure development across the 6 conditions ( P = .023). Maximal wrist angular velocities were 44% lower in all check swing conditions than corresponding full swing conditions ( P < .0001). The time to achieve the maximal wrist angular velocity was longest with the AO–full swing and shortest with the CU–check swing (100.1% vs 7.9% of swing cycle; P = .014). Conclusion: The OF–check swing condition produced the highest total pressure reading on the hook of hamate. Check swing conditions also had the steepest rate of pressure development as compared with the full swing conditions. Clinical Relevance: Batters who frequently check their swings and use an OF or AO grip may benefit from bat modifications or grip adjustment to reduce stresses over the hamate. Athletic trainers and team physicians should be aware of these factors to counsel players in the context of previous or ongoing hand injury.

An investigation of superstitious activity among collegiate baseball players (n = 83) was conducted over the course of three full seasons. A major feature of the investigation was a distinction between behaviors mediated by a conscious belief, and behaviors (presumably nonmediated) established through simple contiguity. Additionally, the baseball players were compared to nonathletes (n = 348) on a variety of traditional indicators of superstitious belief, but the comparison yielded few significant differences. Although the investigation showed that the ballplayers engaged in a high level of superstitious activity, it was concluded that such activity is unremarkable, if not understandable.
