BACKGROUND: Hallux valgus is a complex 3-dimensional deformity, and the modified Lapidus is a commonly used procedure to correct moderate to severe cases. Shortening and elevation of the first ray can occur with this procedure, which may result in increased pressure on the lesser metatarsal heads. However, there is currently no consensus regarding an accepted length and elevation of the first ray following the modified Lapidus. Therefore, the purpose of this study is to evaluate the impact of the position of the first ray on patient-reported outcome measures...

BACKGROUND: Although the rate of venous thromboembolism (VTE) after foot and ankle surgery is low, multiple factors influence risk for individual patients. Furthermore, there are no clear guidelines on which patients may benefit from chemical thromboprophylaxis. Our aim was to assess patients not treated with chemical thromboprophylaxis after foot and ankle surgery, and to report on their specific patient and surgical risk factors for VTE. METHODS: This was a multicenter, prospective, national audit of patients undergoing foot and ankle surgery (including Achilles tendon ruptures) from 68 participating UK centers...

BACKGROUND: It has been assumed that diabetic patients with peripheral neuropathy should not have pain associated with Charcot foot arthropathy. METHODS: During a 19-year period, 14 diabetic patients (15 feet) presented for treatment with pain following resolution of the acute phases of midfoot Charcot foot arthropathy. All were clinically plantigrade with plain radiographic evidence of bony union without deformity. Pain did not resolve with the use of appropriate therapeutic footwear...

BACKGROUND: Operative management of midfoot Charcot arthropathy often involves an extended midfoot arthrodesis with intramedullary bolts for fixation, a method called "beaming." Recently intramedullary nails have been introduced for the same indication, presumably providing stronger fixation. This study compares midfoot fusion nails to bolts with regard to stiffness and compressive ability. Additionally, we assessed how the addition of a subtalar fusion affects the construct. METHODS: Medial column fusions were performed on 10 matched cadaver foot specimens with either a midfoot fusion nail or bolt...

BACKGROUND: Primary arthrodesis of Lisfranc fracture-dislocations is a reliable treatment option, yet concerns remain about nonunion. Nitinol staple use has recently proliferated in midfoot arthrodesis. The purpose of this study is to examine the union rate of primary arthrodesis of acute Lisfranc fracture-dislocations treated with nitinol staples compared with traditional plate-and-screw fixation. The secondary objective is to assess the difference in operative times and reoperation rates...

BACKGROUND: Growing clinical interest in the treatment of acquired foot deformity due to diabetes-associated Charcot foot arthropathy has led to multiple reports of favorable clinical outcomes in patients when their acquired deformity is at the midfoot level. Clinical failures and less than optimal clinical outcomes are achieved when the deformity is at the hindfoot or ankle levels. METHODS: A retrospective review was performed of all patients who underwent surgical correction of diabetes-associated Charcot foot arthropathy with talocalcaneal dislocation over an 18-year period...

BACKGROUND: Syndesmotic malreduction is common and has been associated to an impaired outcome. Various risk factors for DTFJ malreduction have been postulated. The aims of this study were to assess the DTFJ malreduction rate based on (1) the severity of the syndesmotic injury, (2) the anatomy of the tibial incisura, and (3) the fixation device used in patients treated with suture-button systems. METHODS: This retrospective, radiographic study included all adult patients who were treated for an acute, unilateral, and unstable syndesmotic injury with a suture-button system and postoperative bilateral CT imaging...

BACKGROUND: Hallux valgus (HV) is a complex deformity, with many associated risk factors. The flexor hallucis longus (FHL) tendon is a dynamic and potentially deforming force as it bowstrings laterally with HV. We hypothesized that FHL is more laterally inserted in the distal phalanx in cadavers with HV; therefore, it might be also a primary destabilizing force. We aim to compare the FHL distal insertion morphology and its relationship with osseous structures in cadavers with and without HV...

BACKGROUND: Equinus contractures can commonly be due to contractures of gastrocnemius muscle or combined contractures of the gastrocnemius-soleus Achilles tendon complex. The decision to release part or all of the gastrocnemius-soleus Achilles tendon complex is often assessed intraoperatively while the patient is under anesthesia. It remains unknown whether the administration of general anesthesia affects the measurement of passive ankle dorsiflexion. METHODS: The unaffected, nonoperative limb on 46 foot and ankle patients underwent a Silfverskiold test measuring passive ankle dorsiflexion preoperatively and intraoperatively after administration of general anesthesia using an instrumented force-angular displacement goniometer...

BACKGROUND: The influence of social determinants of health (SDH) on postoperative complications has been investigated in several studies, although correlation with Achilles tendon rupture (ATR) repair remains uninvestigated. SDH encompasses several factors, including insurance status and area-based measurements, including the Area Deprivation Index (ADI) and Social Vulnerability Index (SVI), which ranks neighborhoods by social disadvantage. This study investigated the correlation between patient demographics, SDH, and complications following ATR repair...

BACKGROUND: Lisfranc injuries are often treated with open reduction and internal fixation using rigid fixation techniques. The use of flexible fixation to stabilize the Lisfranc joint is a newer technique. The purpose of this cadaveric study is to compare the amount of diastasis at the Lisfranc interval under diminished physiologic loads when treated with a knotless suture tape construct and a solid screw. METHODS: Ten cadavers (20 feet) had native motion at the intact Lisfranc interval assessed at multiple increasing loads (69, 138, and 207 N)...

BACKGROUND: The literature on survivorship and outcomes after revision total ankle replacement (TAR) in the modern era is limited. This study aimed to describe the timing to revision and survivorship after revision TAR. We hypothesized that tibial-sided failures would occur earlier after the primary TAR, and secondary revisions after failure of revision TAR would occur more due to talar-sided failures than tibial-sided failures. METHODS: This is a single-institution retrospective study of TAR patients with minimum 2-year follow-up...
