Insertional Achilles Tendonitis
• Patient Type – Older, less athletic,
overweight and sedentary
pts.
– Young adult males seronegative
spondyloarthropathies
• 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
• Radiographic Exam –
– Ossification in the most
proximal extent of the
achilles insertion
– Spurs may be
incidental findings on xrays and not be
associated with any
SSX - usually chronic
inflammation is
required for pain
Treatment
• 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
• 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
