Cam Morphology

Background Recent studies have demonstrated a high prevalence of femoroacetabular impingement (FAI) in elite men’s ice hockey players, yet little is known about the hips of elite women’s ice hockey players. Purpose The primary purpose of this study was to determine the prevalence of radiographic cam-type FAI in professional women’s ice hockey players in the National Women’s Hockey League (NWHL). The secondary purpose was to analyze the relationship between the presence of cam deformity and both hip range-of-motion (ROM) and age of menarche. Methods Clinical, radiographic and demographic data were collected during player pre-participation physicals. ROM measurements were performed with a goniometer. Alpha angles were measured on 45° Dunn radiographs, with alpha angles >55° defined as cam-positive ( Figure 1). Measurements were performed 3 separate times by 4 investigators. One-way ANOVA, independent means t-test and Pearson correlation coefficients were calculated, with statistical significance set at p<0.05. Results Twenty-six female athletes were included. Average menarchal age was 13.8 ±1.5 years. 24 (92%) had alpha angles >55°; 20 (77%) had bilateral cam deformity. Inter-rater reliability was excellent at 0.86. Intra-rater reliability was also excellent, with mean ICC=0.87 (range= 0.82-0.90 for each rater). There was a significant positive association between age of menarche and alpha angle (p<0.02, Figure 2). There was no association between alpha angle and hip ROM. Conclusion Elite female ice hockey players have a higher prevalence of cam morphology than the general population. The positive association between alpha angle and age of menarche supports the etiological hypothesis of the cam lesion resulting from activity-related stress at the proximal femoral physis during a period of physiologic vulnerability. Professional women’s ice hockey players have a high risk of developing cam morphology of the proximal femur, although each player’s age of menarche may mediate her individual risk for cam lesion development.

Objective Concussion is a common injury in ice hockey, and previous research suggests some misconceptions and unsafe attitudes amongst players. The purpose of this study was to assess sport concussion knowledge, attitudes and the effect of sport concussion history in UK-based male ice hockey players across three levels of competition: professional, semi-professional and amateur. Methods Sixty-one participants across a number of UK ice hockey teams completed the Rosenbaum Concussion Knowledge and Attitudes Survey and reviewed a series of statements to assess knowledge (concussion knowledge index), attitudes (concussion attitude index) and misconceptions of concussion. Results Level of competition and concussion history had no significant effect on concussion knowledge index or concussion attitude index. A positive significant relationship exists between playing experience and concussion knowledge index and concussion attitude index. Statements identified common misconceptions and areas of accurate knowledge regarding concussion symptoms suggesting that male ice hockey players have a higher level knowledge compared to a sample of the UK general public. Playing experience was associated with increased knowledge and increasingly safe attitudes towards concussion. Conclusion Despite knowledge relating to loss of consciousness and correct management of symptoms being generally accurate, there are worryingly unsafe attitudes regarding aspects of concussion. Such attitudes may well pose significant threats to players’ safety and long-term health.
