Toe-Touch Goal After Hip Replacement With Osteoporosis
71-year-old man, 9 months after a posterior-approach total hip arthroplasty, cleared by his surgeon for all exercise at the 6-month review. DXA T-score is -2.8 at L1-L4 with no prior fracture. He walks 30 minutes daily and wants to touch his toes to pick things up and to loosen a stiff back that is worst for 15 minutes each morning. He has been doing seated forward folds with a rounded back, 3 sets of 60 seconds daily, and reports he is about 15 cm from the floor. There is no pain, no falls in the past year, and no neurological symptoms. Medications include a bisphosphonate. He asks whether 90-second holds would speed things up.

There are two concerns. First, osteoporosis with a T-score of -2.8: repeated loaded or end-range spinal flexion with a rounded back increases vertebral compression forces, and combined flexion with rotation is the highest-risk pattern. Ninety-second end-range holds would add exposure without clear benefit. Second, although he is 9 months post-arthroplasty and cleared, posterior-approach precautions such as hip flexion beyond about 90 degrees, adduction, and internal rotation are worth screening when teaching a toe touch; his seated fold likely approaches that flexion limit. Neither concern means no stretching. It means changing the position and the target: teach a hip hinge with a neutral spine, thoracic mobility, and hamstring length in supine, and keep spinal flexion unloaded and mid-range.
2. Design a 6-week plan to help him pick objects from the floor. Include specific exercises, positions, and doses.

The goal is the task, not the toe touch. Priorities: a hip hinge with a dowel behind the back, pushing hips back, 3 sets of 8-10 bodyweight repetitions, then holding a light object; a golfer's lift for floor pickup, a single-leg hip hinge with contralateral hand support, 3 sets of 5 per side; thoracic extension over a chair back or foam roller, 2 sets of 30-45 seconds; a supine hamstring stretch with a strap and softly bent knee, neutral spine, 2-3 sets of 30 seconds per leg on 3-5 days per week at a mild stretch only; and an ankle dorsiflexion drill. Avoid the seated forward fold to end range and any combined flexion-rotation. Progress depth only if morning stiffness and symptoms stay stable, and re-check technique weekly.
3. What would prompt you to send him back to his surgeon or physician rather than continue coaching?
Read the worked answer
Refer for new groin or thigh pain, a sense of instability or giving way, clicking with pain, or sudden loss of hip motion, as these may indicate prosthetic or soft-tissue issues. Refer for new mid-back pain, noticed height loss, or pain after a minor stumble, given osteoporosis and possible fracture. Also refer if morning stiffness lengthens beyond 30-60 minutes, if new neurological symptoms appear, or if balance deteriorates. Because he is on a bisphosphonate and has low bone density, any fall or new spinal pain should be medically assessed before continuing loading. Coaching continues only when symptoms are stable and mechanical.
