shinsplintrunnerHistory and Presenting Symptoms

The patient is a 28-year-old graphic artist who has been running regularly for the past ten years.  She reports the recent onset and gradual worsening of pain in the front of her right lower leg, which is now limiting her physical activity routines.  The leg pain is described as an “aching soreness” that has been getting progressively worse.  She denies any specific injury and has no obvious swelling or discoloration.  Her right leg pain becomes particularly noticeable when she runs downhill or tries to increase her mileage.  There is also now a mild persistent aching in her right buttock region.  She is planning on running her first half-marathon in four months.

Exam Findings

Vitals: This healthy and active young woman weighs 120 lbs. which, at 5’3’’, results in a BMI of 21—she is definitely not overweight.  She is a non-smoker, and her blood pressure and pulse rate are both at the lower end of normal range.

Posture and gait: Standing postural evaluation finds generally good alignment throughout her spine, although she shows evidence of a right posterior ileum.  She has mild calcaneal eversion, with a lower right arch.  Treadmill gait evaluation finds obvious hyperpronation of the right foot and ankle when running.  Measurement finds a standing Q-angle of 26° on the right and 22° on the left (20° is normal for women).

Chiropractic evaluation: Motion palpation identifies a limitation in right sacroiliac motion, with moderate tenderness and loss of endrange mobility. Yeoman’s provocative test elicits moderate pain upon prone extension of the right leg. Neurologic testing is negative.

Primary complaint: Palpation of the right lower leg finds tenderness and tightness of the muscle insertions in the lower third of the tibia, along the anterolateral aspect. Manual testing identifies mild weakness of the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles, and the isometric testing elicits increased pain in these muscles. There are no sensory or reflex changes, and no significant asymmetry in muscle mass or leg diameter. All ankle joint ranges of motion are full and pain-free, bilaterally.

Imaging

No X-rays or other forms of musculoskeletal imaging were requested.

Clinical Impression

“Shin splints” in the deceleration muscles of the right ankle, associated with an elevated Q-angle and foot pronation. This is accompanied by right sacroiliac joint motion restriction and dysfunction.

Treatment Plan

Adjustments: Specific side-posture adjustments for the right sacroiliac joint were provided.  Manipulation of the right navicular and calcaneal bones was performed to decrease the biomechanical stress on the medial arch and subtalar joint.

Support: Custom-made, viscoelastic orthotics were provided to support the arches and decrease impact at heel strike.  Two pairs of stabilizing orthotics were ordered: one designed specifically for her running shoes and the other for her job-related dress shoes.

Rehabilitation: Full-range resistance exercises for the anterior tibialis muscles were performed daily, using exercise tubing, and recorded in a diary. This program progressed to focus on strengthening the eccentric (deceleration) phase in particular. She was able to continue her distance running training program.

Response to Care

She responded well to the sacroiliac and foot adjustments and reported a rapid decrease in her leg symptoms. Within two weeks (after introducing the orthotics), she was able to return to her previous distance-running training program. She reported a subjective feeling of smoother gait and less stressful heel strikes. After a total of 12 treatment sessions, she successfully completed her first half-marathon run. She described moderate, bilateral post-run leg soreness, which resolved within two days. She then returned to regular running with no persistent or recurrent discomfort.

Discussion

Moderate biomechanical asymmetries can become more prominent (and symptomatic) when training volume and levels of physical stress increase.  This seems to be especially true in the lower extremities.  Shock-absorbing orthotics incorporate support for the arches while they reduce pronation and decrease the stress of repetitive heel strikes on the foot and spine.  Anterolateral shin splints indicate a problem with deceleration of the foot at heel strike, which requires improvement of eccentric strength of the anterior tibialis muscle and its co-contractors.
