The vast majority of ankle arthritis is post-traumatic in nature, with rates of 60% to 80%. Symptoms include pain, decreased range of motion, and joint effusion. Diagnostic imaging is helpful in determining the degree of joint degeneration, with MRI and CT scan being the most sensitive.

Ankle fractures are a relatively common injury in the lower extremity. They can be treated with conservative management if they are nondisplaced and only involve the fibula. Nonunions at the fracture site, however, are a potential complicating factor during treatment.

Understanding bone mineral density and its effects on patient outcomes is a useful tool for lower extremity surgeons. Historically, dual-energy X-ray absorptiometry scans have been the gold standard for quantifying bone mineral density. In this study, we look at an indirect way to measure bone mineral density using Hounsfield units on computed tomography.

Article Synopsis
  • - Peroneal subluxation, a condition causing debilitating ankle issues, can arise from either a tear in the superior peroneal retinaculum or laxity in the tendon sheath, affecting how the tendons behave during ankle movement.
  • - A surgical technique called peroneal stabilization was applied to five patients diagnosed with either condition, involving the detachment and reattachment of tendon sheaths using sutures to restore proper tension and prevent dislocation of the tendons.
  • - Post-surgery, all patients experienced improved weight-bearing ability and there were no cases of residual tendon dislocation, though some had minor complications like tendonitis or nerve irritation.

The aim of this study is to use tibial Hounsfield unit measurements from preoperative computed tomography scans of ankle fractures to predict delayed union and nonunion. We hypothesize that patients with lower Hounsfield unit averages, an indirect measure of lower bone mineral density, in the distal tibia are more likely to develop delayed union and nonunion complications after ankle fracture surgery. Patient data from January 2010 to January 2020 were retrospectively analyzed from 2 institutions.

Cavovarus deformity leads to increased peak pressure on the plantar lateral foot, which can lead to ulceration, and can potentially progress to amputation. Techniques have been suggested in the treatment of cavovarus deformity, such as peroneus brevis or longus tendon transfer, anterior tibial tendon lengthening, posterior tibial tendon transfer, or boney resection. This case series shows split anterior tibial tendon transfer as a surgical reconstruction of cavovarus pedal deformity.

Steroid-induced avascular necrosis (AVN) of the lower extremity is a destructive process of the bone found in patients who have been treated with these medications for a variety of medical conditions. There are several proposed etiologies for development of this condition, however much debate still remains for the exact pathophysiology. The main clinical characteristics include edema, arthralgias, and restricted joint range of motion.
