Multicenter Study
Repair of the acute deltoid ligament complex rupture associated with ankle fractures: a multicenter clinical study.
Controversy exists concerning the need for operative repair of the deltoid ligament during management of acute ankle fractures. The purpose of our report was to identify the indications for surgical intervention for deltoid ligament injury in the setting of ankle fractures. Furthermore, we aimed to elucidate the clinical outcomes after deltoid ligament repair in this setting. ⋯ None had evidence of post-traumatic arthritis of the ankle from the clinical examination and radiographs. A reasonable clinical evaluation and surgical repair was executed, with an appropriate repair technique chosen according to the site of deltoid ligament rupture. The results of the present multicenter study have shown that deltoid ligament rupture can be repaired in patients with an unstable medial ankle after fracture fixation and prevent ankle stabilization-related complications.

As the geriatric population in the United States continues to increase, ankle fractures in the elderly are predicted to exponentially increase in the future. As such, these injuries will become a common injury seen by physicians in various fields. Currently, no studies discussing low-energy open ankle fractures in the elderly and/or the mortality rate associated with these devastating injuries have been published. ⋯ Of the 11 patients, 9 (81.81%) had ≥3 comorbidities (i.e., hypertension, diabetes, coronary artery disease, congestive heart failure, and/or chronic obstructive pulmonary disease). The mean size of the medially based ankle wound was 14.18 ± 4.12 cm; 10 (90.90%) were Gustilo and Anderson grade IIIA open ankle fractures. In our study, low-energy open ankle fractures in the elderly, very similar to hip fractures, were associated with a high mortality incidence (27.27%) at a mean of 2.67 ± 2.02 months, and 81.81% of our patients had ≥3 medical comorbidities.

The fifth metatarsal Jones fracture is a well-documented injury occurring at the proximal diaphyseal-metaphyseal junction. Conservative versus surgical intervention has been discussed in published studies for the management of Jones fractures. Solid intramedullary fixation relies on accurate matching of the screw diameter to the intraosseous diameter. ⋯ Intramedullary screw fixation has shown beneficial results in the treatment protocol of fifth metatarsal Jones fractures. Our study has demonstrated that a 4.5-mm cannulated screw is the narrowest diameter screw that can be used in the average fifth metatarsal and still obtain adequate intraosseous purchase. When selecting the appropriate screw, the surgeon must be comfortable selecting the largest screw that will achieve the maximal interface with the dense cortical bone in both the medial to lateral and dorsal to plantar plane.

Case Reports
Irreducible ankle fracture-dislocation due to tibialis anterior subluxation: a case report.
Irreducible ankle fracture-dislocations are rare. Several cases of irreducible ankle fracture-dislocation have been reported in published studies secondary to the tibialis posterior tendon, deltoid ligament, or extensor digitorum longus tendon blocking the reduction. ⋯ The patient's postoperative course was uncomplicated, and the tibialis anterior tendon was functioning at 10 months postoperatively, after which he did not return for follow-up examinations. To our knowledge, this is the first reported case of the tibialis anterior tendon blocking closed reduction of an ankle fracture-dislocation.
