Final answer:
The athletic trainer should suspect trochanteric bursitis, femoral neck stress fracture, and adductor muscle strain as possible causes for the hockey player's hip pain based on the given symptoms and observations.
Step-by-step explanation:
Given the signs and symptoms of the hockey player's right hip pain, the athletic trainer should suspect the following conditions:
- Trochanteric bursitis: Considering the pronounced weight shift to the left side and pronated feet, it's possible that the bursa overlying the greater trochanter of the femur is inflamed, causing the pain.
- Femoral neck stress fracture: The gradual onset of pain and absence of direct trauma could suggest a stress fracture, especially in an athlete with an increase in activity or intensity.
- Adductor muscle strain: Based on the inferior positioning of the right iliac crest and ASIS, it is possible that there is an imbalance or strain affecting the adductor muscles, which attach to the pubis and femur.
With no atrophy or ecchymosis present, and considering the postural observations, it would be less likely for the pain to be due to an abduction muscle strain, hip flexor strain, or lumbar disk herniation; though further testing would be required to rule out these conditions definitively.
