Sports Medicine
Foot and Ankle Surgery

Background:

Acquired hallux varus is an uncommon condition resulting from injury to the first metatarsophalangeal joint (MTPJ).
Previous literature has documented only one prior case of traumatic hallux varus.

Purpose of the Study:

To present a unique case of dynamic hallux varus following trauma to the first MTPJ.
To describe a novel surgical technique for correcting this deformity.
To evaluate the functional outcome and patient satisfaction after surgical intervention.

Main Methods:

Case presentation of a patient with traumatic hallux varus.
Diagnostic imaging including standing weight-bearing and fluoroscopic stress testing to identify dynamic instability.
Surgical correction utilizing a soft tissue anchor for lateral capsular and collateral ligament repair.

Main Results:

The patient presented with a dynamic hallux varus deformity, evident only during fluoroscopic stress testing.
Successful joint stabilization was achieved using a soft tissue anchor for ligamentous repair.
One-year follow-up revealed no limitations in activities of daily living and only mild pain during recreational activities.

Conclusions:

Dynamic hallux varus is a rare but treatable condition.
Soft tissue anchor repair offers a viable and effective surgical option for stabilizing the first MTPJ.
This approach can lead to significant functional improvement and pain reduction in patients with traumatic hallux varus.
