43. Patient Type - Older, less athletic, overweight and sedentary pts. Young adult males -seronegativespondyloarthropathies SSX – Posterior heel pain – dull aching pain Increased with standing, walking or running Aggravated by either active or passive ROM Clinical Exam – Localized tenderness near achilles insertion May have localized edema Achilles tendonitis and retrocalcaneal bursitis often seen with insertional posterior heel pain Tendon thicken at insertion Ankle equinus often associated finding Insertional Achilles Tendonitis

44. Radiographic Exam – Ossification in the most proximal extent of the achilles insertion Spurs may be incidental findings on x-rays and not be associated with any SSX - usually chronic inflammation is required for pain Insertional Achilles Tendonitis

45. Conservative TX – may be helpful initially Training modification in athlete NSAIDs Heel lifts Stretching and strengthening Widening and deepening heel counter on shoes Padding of the posterior heel Night splint for more aggressive stretching Immobilization x 6 weeks Surgical TX – when conservative TX fails and SSX persist Approach – Medial Lateral Posterior – linear or curvilinear Medial and lateral combined Tendon reflection – Longitudinal midline incision of the achilles tendon Lateral to medial reflection of the achilles tendon Minimal reflection if spur is primarily posterior to tendon Treatment

46. Resection of inflamed calcaneal bursa as needed Spur reduction and posterior calcaneal remodeling Achilles reattachment – AJ in NP Soft Tissue anchors – 1 to 3 (inverted triangle) Bone wax to prevent osseous activity due to exposed bleeding cancellous bone Repair any soft tissue attachments to the tendon at this point with 2-0 absorbable suture Treatment
