Background:
The advancement of 3D printing technology has allowed for the use of custom-designed implants for difficult-to-treat foot and ankle pathologies. This study reports on the radiographic and ...functional outcomes of a case series of patients treated with patient-specific 3D-printed titanium implants.
Methods:
Fifteen consecutive patients treated with custom-designed 3D-printed implant cages for severe bone loss, deformity correction, and/or arthrodesis procedures were included in this study. A minimum of 1 year of clinical and radiographic follow-up was required. No patients were lost to follow-up. Patients completed a visual analog scale for pain, the Foot and Ankle Ability Measure Activities of Daily Living score, and the American Orthopaedic Foot & Ankle Society Score outcomes questionnaires preoperatively and at most recent follow-up. All patients had postoperative radiographs and computed tomography (CT) scans to assess bony incorporation. The mean age was 53.3 years (range, 22-74 years) with a mean follow-up of 22 months (range, 12-48 months) for these 15 patients.
Results:
Radiographic fusion verified by CT scan occurred in 13 of 15 patients. There was significant improvement in pain and all functional outcome score measures. All patients who went on to fusion were satisfied with their surgery. There were 2 failures, consisting of 1 infection and 1 nonunion, with an overall clinical success rate of 87%.
Conclusion:
These patients demonstrated the successful use of patient-specific 3D-printed titanium implants to treat complex large bony defects, deformities, and arthrodesis procedures. These implants offer surgeons a novel and promising approach to treat both lower extremity pain and deformity that is not always available with current techniques.

Severe foot and ankle injuries are complex and challenging to treat, often requiring multiple operations to salvage the limb contributing to a prolonged healing period. There is some evidence to ...suggest that early amputation for some patients may result in better long-term outcomes than limb salvage. The challenge is to identify the regional injury burden for an individual that would suggest a better outcome with an amputation. The OUTLET study is a prospective, multicenter observational study comparing 18-month outcomes after limb salvage versus early amputation among patients aged 18–60 years with severe distal tibia, ankle, and foot injuries. This study aims to build upon the previous work of the Lower Extremity Assessment Project by identifying the injury and patient characteristics that help define a subgroup of salvage patients who will have better outcomes had they undergone a transtibial amputation.
Musculoskeletal trauma to the foot is a common presentation to EDs. A Lisfranc fracture dislocation involves injury to the bony and soft tissue structures of the tarsometatarsal joint. While it is ...most commonly seen post high velocity trauma, it can also present post minor trauma. It is also misdiagnosed in approximately 20% of cases. These Lisfranc injuries typically present to EDs with pain particularly with weight bearing, swelling and post a characteristic mechanism of injury. Diagnosis is via clinical examination and radiological investigation-typically plain radiographs and CTs. Once diagnosed, Lisfranc injuries can be classified as stable or unstable. Stable injuries can be immobilised in EDs and discharged home. Unstable injuries require an orthopaedic referral for consideration of surgical fixation.
•Within the literature, there has been scant specific reference to the identification and management of medial ray injuries in midfoot trauma.•The medial ray carries 40% of body weight during stance ...and is essential for adequate foot function.•It is clear from the literature that any injuries involving the medial ray are associated with poorer outcomes.•Restoration of length and stability to this ray is vital when treating these injuries if foot function is to be regained.•We describe in detail injury patterns specific to the medial ray and how to appropriately assess and manage them.
Fractures and dislocations of the midfoot are relatively uncommon but can be life changing injuries. Within the literature, there has been scant specific reference to the identification and management of medial ray injuries in midfoot trauma. Moreover, it is appreciated that these injuries are associated with poor outcomes. We aim to clearly define these injury characteristics and demonstrate fixation techniques.
A retrospective review of the case notes and imaging was conducted for operatively treated midfoot injuries between January 2013 and January 2018.
161 patients were identified, 31 of these with imaging and operative diagnosis suggestive of medial ray injury. Studying these 31 injuries revealed five patterns of injury.
When treating midfoot trauma, it is important to fully understand the injury pattern as this dictates the principles and techniques of fixation. Identification and knowledge of these five injury patterns will aid surgeons in future management of these injuries and may improve treatment outcomes.
Background:
Foot and ankle injuries are increasing in competitive professional and collegiate athletics. Many of these injuries result in considerable missed time from sports and often require ...surgical intervention. To develop and implement effective practice participation strategies, return-to-play protocols, and injury prevention programs, an understanding of injury trends and epidemiology is vital.
Purpose:
This study aimed to evaluate the incidence of foot and ankle injuries in elite athletes participating in 37 sports at a single National Collegiate Athletics Association (NCAA) Division 1 institution.
Study Design:
Descriptive epidemiological study.
Methods:
We evaluated the injury records of all varsity sports at a single NCAA Division 1 athletics program, including 1076 athletes participating in 37 sports. Detailed injury data were prospectively collected in a secure electronic database over a 2-year period. We reviewed the database for all foot/ankle injuries. Inclusion criteria were any foot/ankle injury that was sustained during an NCAA-sanctioned event and subsequently received medical treatment. Independent variables included athlete and injury demographics, missed days, physician visits, imaging results, and whether the injury required surgery. Injury incidence, relative frequency distributions, and sample proportions were dependent metrics for this investigation.
Results:
During the study period, a total of 3861 total musculoskeletal injuries were recorded. There were 1035 foot/ankle injuries (27%). Of all foot/ankle injuries, 21% (218 of 1035) caused the athlete to miss at least 1 day of participation, with an average of 12.3 days of time loss from sport. Furthermore, 27% of athletes with foot/ankle injuries were referred for office evaluation by a physician, and 84% of these required radiologic imaging. The overall injury incidence rate was 3.80 per 1000 athlete-exposures (AEs). The 4 sports with the highest incidence rate (>75th percentile) were women’s gymnastics, women’s cross-country, women’s soccer, and men’s cross country. The most frequently occurring foot/ankle injuries were ankle ligament injuries, tendinopathies or fasciopathies, and bone stress injuries.
Conclusion:
The prevalence of foot/ankle injury in a large NCAA Division 1 athletics program was 27% of total musculoskeletal injuries over a 2-year period, with 21% of these injuries resulting in missed time. There were significantly higher foot and ankle injury incidence rates and more missed time in female athletes and women’s sports.
OBJECTIVES: To determine whether foot pain and plantar pressure are associated with falls in community‐dwelling older adults.
DESIGN: Community‐based cohort study with 12‐month prospective falls ...follow‐up.
SETTING: Sydney and Illawarra statistical regions of New South Wales, Australia.
PARTICIPANTS: Randomly recruited, community‐dwelling adults (158 men and 154 women) aged 60 and older.
MEASUREMENTS: Manchester Foot Pain and Disability Index to establish baseline foot pain and dynamic plantar pressures. Participants were then classified as fallers (n=107) or nonfallers (n=196) based on their falls incidence over the following 12 months.
RESULTS: Fallers had a significantly higher prevalence of foot pain than nonfallers (57.9% vs 42.1%; chi‐square=4.0; P=.04). Fallers also generated a significantly higher peak pressure and pressure‐time integral under the foot than non‐fallers. In addition, individuals with foot pain had a significantly higher peak pressure and pressure‐time integral under the foot than those without foot pain.
CONCLUSION: High plantar pressures generated during gait may contribute to foot pain and risk of falls. Providing interventions to older people with foot pain and high plantar pressures may play a role in reducing their falls risk.
Abstract Background The treatment of limb threatening trauma on the distal tibia or hindfoot often results in posttraumatic osteoarthritis requiring tibiotalocalcaneal (TTC) arthrodesis. The purpose ...of this study was to present a case series of patients undergoing various techniques of joint fusion after bone reconstruction and deformity correction as a salvage procedure. The study should help trauma surgeons making decisions in limb salvage and deformity correction in complex lower leg and foot injuries by presenting options and treatment strategies. Patients and methods Eight patients (4 male, 4 female) after TTC arthrodesis as a definitive procedure after polytrauma or monotrauma involving the distal tibia or hindfoot were the subject of this retrospective analysis. We included patients treated by external ring fixation (1 case), external fixation + wires (1 case), external fixation + screws (1 case) and intramedullary nailing (1 ante- and 5 retrograde; 1 bilateral, 4 unilateral). Initial trauma included open fractures, subtotal foot amputations and closed fractures with failed osteosynthesis and failed ankle joint replacement. Bone defects were treated with callus distraction or segment transport in 5 cases. Various angles were measured to assess foot deformities in the lateral radiographic view and clinical results were presented. Results Independent, pain-free mobilisation with full weight bearing was achieved in all 8 patients. In terms of subjective outcome, all patients reported a highly satisfying result. Complete consolidation at the fusion site was achieved in 8 out of 9 cases with a high rate of adjacent joint arthritis. Angles measures in the lateral radiographs showed values typical for a pes cavus tendency. Conclusion Tibio-talo-calcaneal (TTC) arthrodesis is a viable treatment option for severe post traumatic arthritis and deformity of the ankle and subtalar joint. Despite bad bone quality retrograde intramedullary nailing does provide acceptable results providing stability, low invasiveness and low infection rate. Simultaneous TTC-fusion and tibial lengthening using the Ilizarov ring fixator may be necessary when the surgeon is confronted with large bone defects – often followed by a nailing after lengthening procedure. This study shows that limb preservation after limb threatening trauma with hindfoot injury and multiple fractures of the lower extremity is recommenced as the method of choice with reasonable clinical results.

Background:
Lisfranc injuries are challenging to treat and may have a detrimental effect on athletic performance.
Purpose:
(1) Determine the epidemiological characteristics of Lisfranc injuries at ...the annual National Football League (NFL) Scouting Combine, (2) define player positions at risk for these injuries, and (3) evaluate the impact that these injuries and radiographic findings have on NFL draft position and performance.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
All players who sustained a Lisfranc injury prior to Combine evaluation between 2009 and 2015 were evaluated. The epidemiological characteristics, player positions affected, treatment methods, and number of missed collegiate games were recorded. Radiographic outcomes were analyzed via Combine radiograph findings, while NFL performance outcomes were assessed for all Lisfranc injuries (2009-2013) compared with matched controls in the first 2 years of play.
Results:
A total of 41 of 2162 (1.8%) Combine participants were identified with Lisfranc injuries, of whom 26 of 41 (63.4%) were managed operatively. Players who underwent surgery were more likely to go undrafted compared with players managed nonoperatively (38.5% vs 13.3%, operative vs nonoperative management, respectively; P = .04) and featured a worse NFL draft pick position (155.6 vs 109; P = .03). Lisfranc-injured players when compared with controls were noted to have worse outcomes in terms of NFL draft position (142 vs 111.3, Lisfranc-injured players vs controls, respectively; P = .04), NFL career length 2 years or longer (62.5% vs 69.6%; P = .23), and number of games played (16.9 vs 23.3; P = .001) and started (6.8 vs 10.5; P = .08) within the first 2 years of their NFL career. Radiographs demonstrated that 17 of 41 (41.5%) athletes had residual Lisfranc joint displacement greater than 2 mm compared with the contralateral foot. Lisfranc-injured athletes with greater than 2 mm residual displacement, when compared with matched controls, had worse draft position (156.9 vs 111.2 for Lisfranc-injured players vs controls, respectively; P = .009) and fewer games played (14.4 vs 23.3; P = .001) and started (3.1 vs 10.5; P = .03). Moreover, athletes with greater than 2 mm residual displacement featured worse outcomes across all assessed NFL variables versus athletes with residual displacement of 2 mm or less.
Conclusion:
Lisfranc injuries identified at the NFL Combine have an adverse effect on an NFL athlete’s draft status, draft position, and overall play during initial NFL seasons. In particular, residual displacement of the Lisfranc joint has a detrimental effect on the first 2 seasons of NFL play and may lead to long-lasting negative effects on the athlete’s career.

Foot fractures account for about one-third of lower extremity fractures in adults. They are typically caused by a crush injury or an axial or twisting force on the foot. Patients usually present with ...bony point tenderness and swelling of the affected area. Weight-bearing varies based on the extent of the fracture and the patient's pain tolerance. When a foot or toe fracture is suspected, anteroposterior, lateral, and oblique radiography with weight-bearing should be obtained. The Ottawa foot and ankle rules can help determine the need for radiography after an acute ankle inversion injury. Many foot fractures can be managed with a short leg cast or boot or a hard-soled shoe. Weight-bearing and duration of immobilization are based on the stability of the fracture and the patient's pain level. Most toe fractures can be managed nonsurgically with a hard-soled shoe for two to six weeks. Close attention should be paid to the great toe because of its role in weight-bearing, and physicians should follow specific guidelines for orthopedic referral. Meta-tarsal shaft fractures are managed with a boot or hard-soled shoe for three to six weeks. The proximal aspect of the fifth metatarsal has varied rates of healing due to poor blood supply, and management is based on the fracture zone. Lis-franc fractures are often overlooked; radiography with weight-bearing should be obtained, and physicians should look for widening of the tarsometatarsal joint. Other tarsal bone fractures can be managed with a short leg cast or boot for four to six weeks when nonsurgical treatment is indicated. Common foot fracture complications include arthritis, infection, malunion or nonunion, and compartment syndrome.
Complex foot injuries occur infrequently, but are life-changing events. They often present with other injuries as the result of a high-energy trauma. After initial stabilization, early assessment ...should be regarding salvagability. All treatment strategies are intensive. The initial treatment includes prevention of progression ischemia/necrosis, prevention of infection, and considering salvage or amputation. Definitive treatment for salvage includes anatomic reconstruction with stable internal fixation and early soft tissue coverage followed by aggressive rehabilitation. Prognosis after complex injuries is hard to predict. The various stages of the treatment are reviewed and recommendations are made.
