How common it is, and what nobody has countedEmerging evidence
No study counts the causes of hip pain in golfers. In 910 amateur golfers (median age 60) followed for a season, hip and groin problems came at 0.25 a golfer a year with 0.77 days of golf lost, against 1.26 and 5.93 for the lower back. In 1,170 male golfers, 9.7% had right hip pain and 8.5% left hip pain in the past week; complaints were a little higher on the right, the trail side for most. At a European Tour event, 19.3% of 109 male professionals reported hip pain, and painful lead and trail hips were about equally common (11.9% and 9.1%); a larger cam shape and older age went with worse hip scores.
The NHS lists the common adult causes: a strain or tendonitis after intense or repetitive exercise, osteoarthritis from about 45 with pain worse walking, bursitis on the outside of the hip, a fracture after a fall, and, rarely, a joint infection with a hot, swollen hip and a high temperature.

The lead hip turns, the trail hip pushesEmerging evidence
As you swing through, the lead hip turns inward fast: peak speeds of about 228 degrees a second, against 145 for the trail hip turning outward, in 15 college golfers. The lead hip used about 35 degrees of inward turning in the downswing, more than its full range measured standing upright, though about 85% of its range measured in the golf set-up posture.
The trail hip does the heavy pushing. Trail hip extensor torque was the largest hip load in 20 golfers, the trail leg took about 40% more load than the lead leg in 17 older golfers (a conference abstract), and modelled forces in replaced hips were 5.1 times body weight in the lead hip and 6.6 in the trail hip, below jogging. Professional golfers with limited inward turning at the hip moved their lower backs more in the swing. These are small lab studies.

Elite golfers' hips on MRI: more findings in the trail hipEmerging evidence
In magnetic resonance imaging (MRI) scans of 55 elite golfers, a cam shape (extra bone at the front of the ball of the hip) showed in 7 trail hips and 2 lead hips, and labral tears in 37% of trail hips and 16% of lead hips. That is the reverse of what the lab studies of the lead hip might suggest. Many of these hips didn't hurt, so a finding on a scan isn't proof of the cause.

Walking the courseStrong evidence
Walking 18 holes took about 12,000 steps on three public courses, and 11,245 to 16,667 steps in a review, against about 6,280 riding a buggy. In 16 young competitive golfers, a walked round was 17,007 steps against 6,274 riding, with no change in club or ball speed. Intensity is light to moderate for most golfers, which is good exercise, but a lot of walking for a sore hip.

The rarer causes that need other careEmerging evidence
A hernia can cause a lump in the groin or upper thigh that may get bigger when you cough and smaller when you lie down. A femoral hernia, a small lump at the top of the thigh that mainly happens in women over 50 though it can happen to anyone, needs treating in hospital. In a child, hip pain is often irritable hip, which usually gets better in 1 or 2 weeks, but sudden pain or a limp needs help straight away, as the warning signs say. A joint infection (septic arthritis) is rare and urgent: sudden severe pain in a joint, which is hot and swollen, often with a high temperature, although not everyone has one. A broken hip after a fall, especially in later life, needs 999.

When a scan or test mattersEmerging evidence
Most hip pain in golfers is recognised from the story and an examination. The AAOS describes an examination test for impingement (the knee brought up towards the chest and turned inward) and X-rays for the bone shapes. An X-ray shows arthritis and impingement shapes; an MRI scan, sometimes with dye, looks at the labrum when surgery is being considered. Scans mislead on their own: as our hip labral tear guide reports, a review found tears in 54% of people without hip pain, and many elite golfers' tears were painless. A hip that hasn't settled after 6 weeks with a normal X-ray needs the MRI the warning signs describe.

How it usually goesEmerging evidence
No study follows golfers' hip pain without surgery. Our hip impingement guide gives exercise-based treatment at least 3 months before surgery is considered, and outer hip pain often takes months to settle, as our outer hip guide says.
After keyhole hip surgery (hip arthroscopy), 90 of 95 golfers returned across 4 small series: 20 tour professionals were back at a mean of 4.7 months, and 28 of 29 amateurs at 7.2 months, with pain falling from about 7 to 2 out of 10. After a hip replacement, about 90% of golfers returned in pooled studies. In 1,097 UK golfers with a hip replacement, about a quarter were hitting irons at 6 weeks and 80% were in club competitions at 6 months, with handicaps about one shot higher, and the authors found a buggy helped early on. In a US handicap database, golfers were back in about 62 days and played a little more often than before. No one can promise a date.
