ABSTRACT
Tibialis posterior (TP) tendon ruptures are common after ankle injuries, degenerative processes, or biomechanical instability. The TP tendon decelerates the subtalar joint pronation and internal rotation of the leg during the contact phase. It also plantarflexes and inverts the foot on the leg during the static phase of gait. When this function is lost, the medial longitudinal arch collapses, increasing the length of time of rearfoot pronation, eventually rupturing the TP tendon. Conservative treatment includes immobilization, strapping, antiinflammatories, custom-fabricated orthotics, and physical therapy. If the TP tendon rupture is severe, conservative treatment will provide little relief and surgery is indicated. This case study presents 53-year-old female who presented with left TP tendon rupture with a defect of 6 cm after sustaining an ankle injury that was surgically repaired using a TP tendon fresh frozen allograft and flexor digitorum longus tenodesis. After a 16-month follow-up, the patient was healed without complications and returned to preinjury activity. We believe that surgically repairing a TP tendon rupture with a TP tendon allograft and flexor digitorum longus tenodesis can be 1 of the treatment options for patients with extensive disruption of the TP tendon.

Squamous cell carcinoma (SCC) has been commonly reported by foot and ankle specialists. Marjolin's ulcer is a malignancy that involves a posttraumatic scar or ulceration that can develop into SCC from chronic neuropathic pedal wounds, venous stasis, or decubitus ulcerations. Most Marjolin's ulcers are found in the lower extremity, specifically the feet, and it is twice as common in females as males. Biopsy of the tumor is the reference standard to diagnose SCC, and wide excision of SCC is the most common treatment option. The present case study describes an 83-year-old diabetic wheelchair-bound female who presented to the wound care clinic with a right heel nonhealing pressure ulceration. After biopsy and surgical excision, the patient was found to have SCC. This case was followed up for 5 years in which the patient had successful excision of the tumor with no recurrence. The clinical significance of our case study is to assist in the diagnosis, management, and prognosis of patients with SCC. In addition, this study has shown that adequate excision of the tumor margins and depth is necessary to prevent potential recurrence and metastasis.
