Anterior Tibial Tendon Rupture ICD-10

Anterior Tibial Tendon Rupture ICD-9

  • 727.68 Rupture of tendon, nontraumatic, other tendons of foot and ankle

Anterior Tibial Tendon Rupture Etiology / Epidemiology / Natural History

  • Rare
  • May result from forced plantar flexion of the foot against resistance. 
  • Associated with direct trauma, gout, inflammatory arthritis, local steroid injections, and diabetes.
  • Associated with cross country skiing. 

Anterior Tibial Tendon Rupture Anatomy

  •  Tibialis anterior:  Innervation=deep peroneal nerve.  Origin=lateral tibia.  Insertion=medial cuneiform/1st metatarsal.  Action=dorsiflex and invert the foot.

Anterior Tibial Tendon Rupture Clinical Evaluation

  • Weakness in dorsiflexion of the foot.
  • Foot drop.  May not develop initially.  Ambulate with a steppage gait (slapping foot)
  • Elderly patients may complain of vague dorsal foot pain.
  • May have tender small mass on the mediodorsal foot or along tibialis anterior.  Definite gap in tendon may be palpated.
  • Compare contour of tibialis anterior to contralateral side while patient actively dorsiflexes foot. 

Anterior Tibial Tendon Rupture Xray / Diagnositc Tests

  • Ankle xrays, foot xrays: indicated to rule out osseous lesions.   Generally normal. 
  • Ultrasound: demonstrates tendon rupture
  • MRI: demonstrates tendon rupture

Anterior Tibial Tendon Rupture Classification / Treatment

  • Younger, healthy, active patient ;  Surgical repair results in improved patient satisfaction 
  • Elderly, nontraumatic:  molded AFO for 6 months and then for long periods of activity; repair extremely difficult in older pts with poor tissues

Anterior Tibial Tendon Rupture Complications

Anterior Tibial Tendon Rupture Follow-up Care

  • Isokinetic testing has shown decreased dorsiflexion and inversion strength compared with the uninvolved side even after successful surgical repair.
