Return to Play
The athlete may be expected to return to play without restrictions when the following goals have been achieved:
- Resolution of symptoms
- Resolution of any positive physical examination findings (eg, limping, tenderness to palpation)
- Adequate performance of sports-specific practice drills, without recurrence of symptoms or physical examination findings
Complications
- Complications due to trochanteric bursitis (greater trochanteric pain syndrome, GTPS) include progressive or persistent pain, with associated limping and decreased mobility.
- Potential complications due to focal corticosteroid injection include bleeding, bruising, infection, and allergic reactions. Necrotizing fasciitis from a single steroid injection of the greater trochanteric bursa has been reported.[15]
- In patients with diabetes, transient elevation of blood glucose levels may occur after a corticosteroid injection.
- Intravascular injection could potentially cause cardiac arrhythmia due to the local anesthetic.
- Peripheral nerve dysfunction is possible if the injection is administered very near or within a major nerve.
Prevention
Prevention may include emphasis on an appropriate training schedule for the patient and avoidance of constant unidirectional activities on banked surfaces. For example, if running must be done on a banked surface, ideally, the athlete should spend half the time running each way on the embankment to avoid always overloading the same tissues on one side of the body. Athletes who participate in contact sports (eg, hockey) should be educated regarding the appropriate use and size of protective padding. Athletes in endurance sports should be educated in the importance of ITB stretching and hip abductor strengthening.
Prognosis
Most patients respond well to a combination of corticosteroid injection and physical therapy. Some patients may require a repeat corticosteroid injection.
A retrospective study of 164 patients who presented with trochanteric pain found that after 1 year, at least 36% affected patients were still symptomatic, and after 5 years, 29% were still symptomatic; thus, many patients developed chronic pain at this site.[5] Patients with osteoarthritis in the lower limbs had a 4.8-fold risk of persistent symptoms after 1 year, as compared with patients without osteoarthritis.
Patients who were treated with corticosteroid injection were shown to be 2.7 times less likely to have chronic pain at this site at 5 years relative to those treated without such injections.[5]
Education
As with any medical condition, educate the patient regarding the nature of the condition, the causative factors, and the treatment plan.
As with any injection, educate and instruct the patient to watch for any signs or symptoms of local infection at the injection site.
As with any corticosteroid injection, inform diabetic patients that they may experience a transient increase in blood glucose levels. Patients should also be made aware that symptomatic improvement from the corticosteroid usually does not begin to take effect until a few days after the injection. In fact, they may experience a transient mild increase in symptoms during the time in which the local anesthetic has worn off but when the steroid has not yet begun its therapeutic effect.
