Case Series: Allograft Tibiotalocalcaneal Arthrodesis Utilizing Fresh Talus.

Background: Talar body osteonecrosis can be a difficult condition to treat. Recent reports highlight a high rate of failure with the use of femoral head allograft. Additionally, higher rates of failure have been reported in diabetics and smokers.

Surgical Considerations for Vitamin D Deficiency in Foot and Ankle Surgery.

Vitamin D deficiency affects nearly one-sixth of the world's population and is common in patients undergoing foot and ankle surgery. Vitamin D is critical for calcium homeostasis and plays an important role in the maintenance of bone health. Patients undergoing foot and ankle procedures can be evaluated preoperatively with vitamin D level testing, and deficiencies can be addressed with either preoperative or postoperative supplementation.

Tibiotalocalcaneal Arthrodesis With Bulk Talar Allograft for Treatment of Talar Osteonecrosis.

Unlabelled: Talar body osteonecrosis can be a devastating, painful condition that is difficult to manage surgically when conservative treatments have failed. With early disease, nonoperative treatments can prolong the need for operative correction in the young patient. Later stage disease with extensive involvement may require a tibiotalocalcaneal (TTC) arthrodesis to retain functionality of the limb.

Distal fibular malrotation and lateral ankle contact characteristics.

Background: Any amount of malreduction of the syndesmotic joint compared with the uninjured syndesmosis has been associated with an adverse effect on functional outcome. The amount of malrotation that may lead to clinically relevant pressure change in this joint has not been reported. Our purpose was to determine whether small degrees of external and internal malrotation would be associated with statistically significant changes in contact pressure in the tibiofibular and talofibular articulations.

Arthroscopic Correlates of Subtle Syndesmotic Injury.

Background: Arthroscopic criteria for identifying syndesmotic disruption have been variable and subjective. We aimed to quantify syndesmotic disruption arthroscopically using a standardized measurement device.

Methods: Ten cadaveric lower extremity specimens were tested in intact state and after serial sectioning of the syndesmotic structures (anterior inferior tibiofibular ligament [AiTFL], interosseous ligament [IOL], posterior inferior tibiofibular ligament [PiTFL], deltoid).

Pain reporting, opiate dosing, and the adverse effects of opiates after hip or knee replacement in patients 60 years old or older.

Our goal was to determine whether there were age-related differences in pain, opiate use, and opiate side effects after total hip or knee arthroplasty in patients 60 years old or older. We hypothesized that there would be no significant differences between age groups in (1) mean pain score, (2) opiate use after adjusting for pain, or (3) opiate side effects after adjusting for opiate use and pain score. We retrospectively reviewed the electronic and paper charts of all patients undergoing total joint replacements at our institution over 3 years who met the following criteria: (1) 60 years old or older, (2) primary single total knee or total hip replacement, and (3) no preoperative dementia.
