Zadek Osteotomy for Treatment of Haglund's Syndrome

Condition(s) studied

Study summary

Haglund's syndrome is an abnormality of the bone and soft tissues in the foot. An enlargement of the bony section of the heel (where the Achilles tendon is inserted) triggers this condition.

* symptom includes insertional Achilles tendinopathy (IAT), The patient with HS often has a red, irritated, painful heel. And they often complain the enlargement of the posterior heel, which make it more difficult to footwear or sport
* Zadek described the Zadek Osteotomy option for the treatment of Haglund's syndrome This operation can change the calcaneus' anatomical length and elevate the distal insertion point of the Achilles tendon

\- It is a prospective case series study that will be done in Orthopedics and Traumatology department of Sohag university hospitals on patients suffering from Haglund's syndrome and treated by Zadek osteotomy
* This study aims to evaluate short term clinical, radiological and functional outcomes of Zadek osteotomy for treatment of Haglund's syndrome

Eligibility

Primary outcome measure(s)

• Primary outcomes for a Zadek osteotomy in Haglund's syndrome include: pain relief. — From enrollment and follow up to the end of 24 weeks
  \- Pain Reduction: Marked improvement in pain, often measured by a Visual Analogue Scale (VAS) score, is a primary outcome, with significant reductions in pain intensity and frequency reported after the procedure.
• functional improvement (measured by score VISA-A). — From enrollment and follow up to the end of 24 weeks
  Functional Improvement: VISA-A (Visual Analogue Scale for Achilles Tendinopathy) Score: A successful outcome is characterized by an improvement in the VISA-A score, reflecting better function for the Achilles tendon.
• radiological changes to the calcaneus — From enrollment and follow up to the end of 24 weeks
  calcaneal length and tuberosity ratio (X/Y Ratio): The osteotomy modifies the calcaneus by shortening it and rotating the posterosuperior tuberosity, which reduces impingement on the Achilles tendon. calcaneal pitch angle(calcaneal inclination angle): Studies have shown a reduction in the calcaneal pitch angle after Zadek osteotomy which is a relevant radiological parameter for Haglund's deformity
• improved ankle motion (dorsiflexion), — From enrollment and follow up to the end of 24 weeks
  Improvements in scores like the Tegner scale show a patient's ability to return to sports or other activities at a pre-injury level The Zadek osteotomy is known to improve the range of motion, specifically an increase in ankle dorsiflexion.
• Patient Satisfaction: — From enrollment and follow up to the end of 24 weeks
  High rates of patient satisfaction are a key indicator of a successful procedure, with many patients reporting positive experiences post-surgery
