First MTP joint injuries: MR imaging findings in surgically managed patients.

OBJECTIVES: Determine whether MR imaging findings or demographics predict surgical management in patients with first MTP joint injuries. MATERIALS AND METHODS: Retrospective study of 161 forefoot MRs for traumatic first MTP injury (M:F 92:69, mean age 33 ± 13 yrs.). Two radiologists reviewed imaging for ligamentous, osseous, and tendinous injuries. Ligaments and tendons were graded as 0:normal, 1:sprain or strain, 2:partial tear, 3:complete tear. Osseous injuries were classified as edema, fracture, or cartilage injury. Clinical data obtained included sex, age, injury acuity, sport participation, level of sport, and treatment. Imaging findings and demographic data were assessed to determine predictive factors for surgical management. Statistics included kappa, chi-squared, Fisher's exact, and logistic regression. RESULTS: Logistic regression (odds ratio [95% CI], p-value) showed that grade 2 or 3 injuries of the plantar ligamentous complex (2.87, [1.10, 7.48], p = 0.031), grade 2 or 3 injuries of the medial collateral ligament (3.24, [1.16, 9.08], p = 0.025), and participation in collegiate or professional sports (4.34 [1.64, 11.52], p = 0.003) were associated with an increased rate of surgical intervention. k = ligamentous injury (0.71-0.83), osseous trauma (0.88-0.95), and tendon injury (0.78). All other imaging findings and demographic factors were not significant predictors of surgery (p > 0.05). CONCLUSION: Participation in collegiate or professional sports and tears of the plantar ligamentous complex or medial collateral ligament predicted surgical management in patients with first MTP trauma.

Outcome of Turf Toe Injuries in NFL Players.

The increase in artificial turf in the 1970s was thought to have contributed to increased incidence of turf toe injury in National Football League (NFL) players. To our knowledge, there are no publications that have analyzed the impact of this injury on performance. This is a retrospective case series. Online resources were used to identify NFL players who sustained a turf toe injury between the 2011 and 2014 seasons. The performance of each offensive skill player was analyzed separately by calculating their power rating (PR) over 6 seasons. Injured offensive skill players were then compared to a control group consisting of all RBs and WRs without a turf toe injury who competed in the 2012 season. Seventy-one turf toe injuries were identified. Twenty-nine occurred on grass, 29 on turf and the playing surface of 13 injuries could not be identified. The average PR prior to injury was 105.7/season (7.3/game), 87.3 (6.9/game) for the season of injury and 115.5 (8.1/ game) for postinjury seasons. The PR was not significantly different after a turf toe injury compared to before injury or to uninjured control player. There was no significant difference in NFL players' performances after turf toe injury based on power ratings.

Hallux sesamoid complex imaging: a practical diagnostic approach.

A wide variety of pathologies can affect the hallux sesamoid complex of the foot, including traumatic, micro traumatic, degenerative, inflammatory, vascular, infectious, and neoplastic conditions. Symptoms are quite nonspecific, mainly related to pain in the plantar surface of the first metatarsal head. In this context, imaging is important for the etiologic diagnosis of hallux sesamoid complex pathology with implications in patient management. The hallux sesamoid complex has a complex anatomy, and pathologic processes of this region are poorly known of radiologists. Besides, some entities such as "sesamoiditis" remain poorly defined in the literature. Schematically, conditions affecting sesamoids will be divided into two major groups: intrinsic anomalies (sesamoid bone being the center of the pathologic process) and extrinsic anomalies (diseases secondarily involving sesamoid bones). Thus, in this article, after a review of anatomical key points and pathologies affecting the hallux sesamoid complex, a practical multimodality approach for the diagnosis of hallux sesamoid pathologies will be proposed.

First MTP joint instability - Expanding the concept of "Turf-toe" injuries.

BACKGROUND: Although the classic definition of the Turf-toe injury refers to a very specific clinical and pathological picture, we think that the concept can be broadened to encompass a wide variety of traumatic lesions of the first metatarsophalangeal joint (MTP1). These are lesions typically difficult to diagnose, with a large variation of outcomes and a potential to impair patients' functional performance on a definitive and perennial basis. The objective of this study is to present the result obtained by treating 24 cases of traumatic injuries to the MTP1 joint in a midterm follow-up time. METHODS: In the period from 1999 to 2016, 24 patients were treated with MTP1 joint instability - "Expanded Turf-toe" - diagnosis. All patients were performing sports activities when they were injured: soccer (33%); martial arts (17%); running (13%); tennis (8%); olympic gymnastics (8%) and others (basketball, slalom, motorcycling, surfing, and ballet) (21%). Injuries were classified as Grade I (2 patients - 8%), Grade II (8 patients - 33%) and Grade III (14 patients - 59%) lesions. All patients with grades I and II were treated conservatively whereas those classified as grade III were treated surgically. RESULTS: After an average follow-up of 4.5 years we observed an improvement in the AOFAS hallux score from 42 to 82 points after treatment (p<0.001). The most frequent cause was axial load with various direction of stress at the first MTP. The mechanism of lesion varied among extension with hallux varism (42%), pure hyperextension (25%), extension with hallux valgism (21%), pure hyperflexion (8%) and hyperflexion with hallux valgism (4%). A separate analysis of each group showed a significant improvement in AOFAS Hallux scores after treatment: 51-84 (p<0.001) and 36-81 (p<0.001) for conservative and surgical groups, respectively. Four patients with GIII injuries (29%) and two with GII injuries (20%) did not resume their previous activities. Although pre-treatment AOFAS hallux scores were significantly different between groups, post-treatment scores were similar (p=0.615). CONCLUSIONS: Turf-toe is a serious injury that may prevent a high percentage of patients from resuming their previous physical activities. Mechanism of lesion might be varied generating a wide range of lesions that fit into the expanded concept of the Turf-toe injury. Both forms of treatment lead to satisfactory results if well conducted. The correct identification, classification, and grading of first metatarsophalangeal joint (MTP) instability helps in decision making and selection of the adequate treatment. LEVEL OF EVIDENCE: Level IV, retrospective case series.

From injury to rehabilitation: How kinesiology taping helps patients with first metatarsophalangeal joint sprain (turf toe) in pain reduction, gait parameters and functional ability improvement. A randomized clinical trial.

Objective: Turf toe is a common sports injury that may affect mobility and functional ability. For complete recovery, rehabilitation modalities are required to overcome these issues. This study investigated whether kinesio taping (KT) would reduce pain, improve gait performance, and enhance the functional capacity of turf toe patients undergoing physical therapy. Methods: sixty patients with grade II turf toe (age; 25-30 years) assigned randomly into three treatment groups; KT applied alongside an exercise program conducted three times/week for 12 successive weeks. (KT group; n = 20), placebo taping plus exercise (Placebo group; n = 20), or exercise only (Control group; n = 20). Pain, gait parameters, and functional ability assessed using VAS, 3D gait analysis, and 6MWT respectively pre- and post-treatment. Results: There was a significant post-treatment decrease in VAS score in the KT group lower than the control or placebo group and a significant increase in 6MWT distance in the KT group higher than the control or placebo group (p < 0.001). Additionally, there was a significant post-treatment increase in step length, stride length, cadence and velocity of KT group higher than control and placebo group (p < 0.05). There was no significant difference in gait parameters between control and placebo groups post treatment (p > 0.05). Conclusions: The findings of the study demonstrated that KT is a useful complementary modality to exercise in patients with turf toe, as it may result in more favorable improvements to pain, gait characteristics, and functional abilities. Further studies should be conducted to assess the long-term effects, different KT application methods, and tailored treatment protocols on turf toe.

Outcomes of Surgical Management of Turf Toe: 12-Year Results.

Background "Turf toe" is a classical capsuloligamentous injury to the plantar surface of the metatarsophalangeal (MTP) joint of the great toe. The name is synonymous with injuries sustained on artificial turf or hard grounds. The classical injury pattern is a hyperdorsiflexion injury with an axial load. The outcomes of these injuries are unpredictable and there are no clear guidelines for the management of these injuries. These injuries are debilitating and can lead to long-term problems and inability to return to pre-injury activity level if missed. We present a long-term surgical follow-up of severe grade 3 turf toe injuries. Methods In the period from 2011 to 2022, we treated 20 patients with turf toe/MTP joint instability. There were 10 football injuries (50%), six running injuries (30%), two gymnastic injuries (10%), one motorcycle injury (0.5%), and one was a ballet dancer (0.5%). All the grade 1 and 2 injuries were treated conservatively with rest, ice application, and splinting of the toe. Grade 3 injuries were treated surgically and strict rehabilitation protocol was followed. Results The mean age at surgery was 32.7 years and the average patient follow-up was 7.5 months after surgery. The Manchester-Oxford Foot Questionnaire (MOXFQ) score showed a statistically significant improvement from a mean of 73.0 (median = 75) preoperatively to 28.1 (median = 28.6) postoperatively (median improvement = 46.4, P = 0.022). Similarly, there was a significant improvement in pain score, which showed an improvement from a mean of 72.9 (median = 70.0) preoperatively to a mean of 22.9 (median = 25.0) postoperatively (median improvement = 51.3, P = 0.022). Conclusion Turf toe is a serious injury that may prevent a high percentage of patients from resuming their previous physical activities. The correct identification, classification, and grading of the first MTP joint instability helps in decision-making and achieving good surgical outcomes.

Turf Toe Injuries in the Athlete: an Updated Review of Treatment Options, Rehabilitation Protocols, and Return-to-Play Outcomes.

PURPOSE OF REVIEW: First metatarsophalangeal joint sprains or turf toe (TT) injuries occur secondary to forceful hyperextension of the great toe. TT injuries are common among athletes, especially those participating in football, soccer, basketball, dancing, and wrestling. This review summarizes the current treatment modalities, rehabilitation protocols, and return-to-play criteria, as well as performance outcomes of patients who have sustained TT injuries. RECENT FINDINGS: Less than 2% of TT injuries require surgery, but those that do are typically grade III injuries with damage to the MTP joint, evidence of bony injury, or severe instability. Rehabilitation protocols following non-operative management consist of 3 phases lasting up to 10 weeks, whereas protocols following operative management consist of 4 phases lasting up 20 weeks. Athletes with low-grade injuries typically achieve their prior level of performance. However, among athletes with higher grade injuries, treated both non-operatively and operatively, about 70% are expected to maintain their level of performance. The treatment protocol, return-to-play criteria, and overall performance outcomes for TT injuries depend on the severity and classification of the initial sprain. For grade I injuries, players may return to play once they experience minimal to no pain with normal weightbearing, traditionally after 3-5 days. For grade II injuries, or partial tears, players typically lose 2-4 weeks of play and may need additional support with taping when returning to play. For grade III injuries, or complete disruption of the plantar plate, athletes lose 4-6 weeks or more depending upon treatment strategy.

Open Reduction and Screw Fixation of a Diastatic Bipartite Hallux Sesamoid in Turf Toe Injury: A Case Report.

We present a case of a 25-year-old male professional soccer player who complained of severe pain over the first metatarsal head after opponent contact during a soccer game. Clinical findings showed swelling and tenderness. Initial radiographs showed a diastasis of a bipartite medial sesamoid between the fragments as compared to radiographs taken 4 years earlier of the same foot. A computed tomography scan was performed objectifying the widened interval and also showing an angulation of the proximal fragment. Open reduction and screw fixation were performed, leading to adequate positioning of the 2 bipartite fragments. The patient showed good clinical recovery and returned to the same performance level. Turf toe injury with diastasis of a medial bipartite sesamoid can be treated successfully with this operative technique.Levels of Evidence: Level V: Case report.

Arthroscopic Repair of Chronic Plantar Plate Tears of the First Metatarsophalangeal Joint: A New Surgical Technique With Patient Outcomes.

Background: Most plantar plate tears of the first metatarsophalangeal joint can be treated successfully by nonoperative means. Primary repair may be indicated to restore continuity of the plantar structures and joint stability. Inadequate or failed nonoperative treatment may cause persistent pain and disability and thereby represent a career-threatening injury to an athlete. The chronic plantar plate tears are difficult both to diagnose and to treat. When surgical treatment is indicated, traditionally a wide plantar or 2 parallel incisions are used. An arthroscopic approach allows for verification and visualization of the injury and, at the same time, repair of the injury. Purpose: To describe findings of plantar plate tears, present a new arthroscopic procedure for plantar plate tear repair, and present the outcomes after surgery. Study Design: Case series; Level of evidence, 4. Methods: This was a retrospective study on the first 10 patients treated with the arthroscopic technique. The patients underwent surgery between June 2017 and January 2021. Patient data, clinical symptoms and findings, and operative details were obtained from the patient records. Patients were contacted via email to complete patient-reported outcome measures (Manchester Oxford Foot Questionnaire [MOxFQ] and Numeric Rating Scale [NRS] for pain). Results: Four female and 6 male patients with a median age of 24 years (range, 12-44 years) were operated on at a median of 20 months (range, 2-38 months) after injury. Of the 10 patients, 8 had a hyperextension injury of the first metatarsophalangeal joint and 7 had a subtle valgus malalignment of the hallux; 8 patients were injured during sport activity. All patients reported plantar pain at pushoff. All but 1 patient returned to the same level of preinjury activity within 6 months. At a median of 29 months (range, 7-49 months) after surgery, the median MOxFQ score was 6 (range, 0-41) and the median NRS pain score was 0. Conclusion: Arthroscopic plantar plate repair of chronic plantar plate tears resulted in a high rate of return to activity/sport and excellent outcome scores.

Pediatric Sports Injuries.

Recreational sports are more popular, with many athletes involved year-round in multiple sports and on multiple teams. Most athletes do not take proper rest, making them more susceptible to stress-related injuries. There are numerous sports-related injuries in the foot and ankle. These issues can be non-traumatic, due to chronic repetitive stresses, or traumatic. Most of these injuries are managed conservatively, and athletes do well and return to play, while some do better with operative management. This article discusses a few of the sports injuries that are common in the leg, foot, and ankle and the recovery process.

Assessment and Treatment of Sports Injuries to the First Metatarsophalangeal Joint.

Turf toe injuries have been increasing in numbers in recent years. Injury to the plantar restraints of the first metatarsophalangeal joint can lead to significant disability in athletes, affecting their push-off and ability to perform on the athletic field. Most turf toe injuries can be treated conservatively with rest, ice, compression, immobilization if needed, and a dedicated rehabilitation program; however, in some injuries, the plantar restraints are torn and the joint becomes unstable. If necessary, turf toe injury and its many variants can be surgically repaired with the expectation that the athlete will be able to return to play.

Imaging of Turf Toe.

Turf toe is a common injury of the hallux metatarsophalangeal (MTP) joint in athletes which is the result of hyperdorsiflexion injury. While the term turf toe has been used to describe a variety of first MTP joint injuries, the term is now typically used in imaging to describe tearing or injury to the plantar plate complex. This review article will cover normal anatomy of the first MTP joint, mechanism of injury, typical imaging findings in normal individuals on MRI and ultrasound, as well as the most common patterns of injury.

In-Season Management of Acute and Subacute Sports Foot Injuries.

In athletes, foot injuries present with a variety of mechanisms, severity, and implications for return to play. Although potentially given less attention than knee and shoulder injuries by the team physician, foot injuries are common and thus require knowledgeable consideration. In this article, we review the anatomy, presentation, workup, and management of several of the most common athletic foot injuries, including turf toe, Lisfranc injuries, Jones fractures, and navicular stress fractures. The goal is to provide the team physician with the information necessary to evaluate and manage these injuries on the sideline and in the training room.

Turf Toe Review.

Turf toe is a term used to describe myriad injuries to the metatarsophalangeal complex of the great toe, which have been associated with the introduction of artificial turf surfaces in sport. If not diagnosed early and treated properly, these injuries can result in chronic pain and loss of mobility. Accurate injury grading through physical exam and advanced imaging is essential to guide treatment, thereby minimizing long-term complications and maximizing an athlete's recovery and return to play. Levels of Evidence: Level V.

Outcomes of Chronic Turf Toe Repair in Non-athlete Population: A Retrospective Study.

BACKGROUND: Turf toe injuries, though most common in athletes, can also occur in non-athletes. No study exists in the current literature investigating operative outcomes in non-athlete patients with chronic turf toe injury. In this study, we present our outcomes on operatively treated turf toe injuries in non-athletes in the only cohort yet studied. METHODS: Using ICD-10 codes, we assembled a cohort of 12 patients who underwent operative repair of chronic turf toe injury from January 2012 through January 2018 at the investigating institution. These 12 patients were evaluated to determine demographic information, method of injury, length of time from injury to surgery, clinical and radiologic characteristics of the injury, and operative outcomes including mean preoperative and postoperative VAS (Visual Analog Scale) scores, preoperative and postoperative FFI (Foot Function Index) scores, and postoperative complications. RESULTS: On initial clinical presentation, all 12 patients had local tenderness with associated painful range of motion. Four patients had restricted range of motion, all patients had a positive Lachman test, two had local edema, and eight had hallux valgus deformity. Mean VAS improved from 4.6 (range 2-9) to 1 (range 0-4). Mean FFI improved from 102.5 (range 56-177) to 61.75 (range 23-144). All patients had a negative Lachman test at final follow-up. No patients developed major complications or required revision surgery. CONCLUSIONS: Our study is the first to investigate operative outcomes following chronic turf toe injury in non-athlete patients. Based on our study, surgeons and patients can expect significant improvement in overall pain and function following surgery.

Turf Toe, Traumatic Hallux Valgus, and Hallux Rigidus -What Can I Do After an Metatarsophalangeal Fusion?

Turf toe injuries should be recognized and treated early to prevent long-term disability. The accurate clinical assessment and radiological evaluation of appropriate cases is important. Both conservative and surgical treatments play a major role in getting athletes back to their preinjury level. There are more recent reported case series and systemic reviews that encourage operative treatment as early as possible for grade III turf toe injury. If the patient presents late from a traumatic hallux injury with subsequent degenerative changes or has hallux rigidus from other etiologies, a first metatarsophalangeal arthrodesis should be considered to minimize pain and improve function.

ACR Appropriateness Criteria® Acute Trauma to the Foot.

Acute injuries to the foot are frequently encountered in the emergency room and in general practice settings. This publication defines best practices for imaging evaluations for several variants of patients presenting with acute foot trauma. The variants include scenarios when the Ottawa rules can be evaluated, when there are exclusionary criteria, and when suspected pathology is in anatomic areas not addressed by the Ottawa rules. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

The Effect of Turf Toe Injuries on Player Performance in the National Football League.

Background: "Turf toe" results from hyperdorsiflexion of the first metatarsophalangeal joint, injuring the plantar capsuloligamentous complex. We hypothesized that National Football League (NFL) player performance following turf toe injury would decrease in comparison to controls at the same position. Methods: Demographics, return to play, and season performance data on players sustaining turf toe injuries in the NFL from 2010-2015 were collected. An Offensive Power Rating (OPR=[total yards/10]+[total touchdowns x6]) or Defensive Power Rating (DPR=total tackles+[total sacks x2]+[total interceptions x2]) was calculated for each player. Control data were collected for NFL players in 2013 with no history of turf toe injury. Statistical analysis was performed using Wilcoxon Rank Sum tests. Results: Twenty-four injured players and 436 controls were included. Nineteen players returned to play within the regular season of injury (mean 36.7 ± 28.9 days). Seventeen players were removed from team injury reports for turf toe within the regular season (mean 42.6 ± 26.2 days). Three players required season-ending surgery. Comparison of 1-year post- versus pre-injury revealed an insignificant median OPR difference (-18.9 IQR -43.4 to 10.3 vs. control -12.2 IQR -46.2 to 47.7, p = 0.328) and median DPR difference (-1.0 IQR -26.0 to 17.0 vs. control 2.0 IQR -15.0 to 18.0, p = NA). Comparison of 2-year data revealed no significant median OPR difference (-32.6 IQR -122.2 to 1.0 vs. control -20.7 IQR -72.6 to 44.7, p = 0.327) and median DPR difference (-5.0 IQR -19.0 to 6.0 vs. control -4.5 IQR -22.0 to 12.5, p= NA). Conclusions: Turf toe results in significant loss of playing time. Despite the long recovery period, NFL players have similar performance following injury compared to controls. The effect of turf toe injuries on performance is variable.Level of evidence: IV.

Return to Sport After Turf Toe Injuries: A Systematic Review and Meta-analysis.

BACKGROUND: The prevalence of turf toe injuries has increased in recent years. However, uncertainty remains as to how to optimally treat turf toe injuries and the implications that the severity of the injury has on outcomes, specifically return to sport (RTS). PURPOSE: To determine RTS based on treatment modality and to provide clinicians with additional information when comparing operative versus nonoperative treatment of turf toe injuries in athletes. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review and meta-analysis was performed using the PubMed/Ovid MEDLINE/PubMed Central databases (May 1964 to August 2018) per PRISMA-IPD (Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Individual Participant Data) guidelines. RTS, treatment, severity of injury, athletic position, and sport were recorded and analyzed. RESULTS: Of 858 identified studies, 12 met the criteria for the final meta-analysis. The studies included 112 athletes sustaining a total of 121 turf toe injuries; 63 (52.1%) of these injuries were treated surgically, while 58 (47.9%) were treated nonoperatively, and 53.7% were classified by the grade of injury (grade I, n = 1; grade II, n = 9; grade III, n = 55). Overall, 56 (46.3%) injuries could not be classified based on the data provided and were excluded from the final analysis. The median time to RTS for patients treated nonoperatively was 5.85 weeks (range, 3.00-8.70 weeks) compared with 14.70 weeks (range, 6.00-156.43 weeks) for patients treated surgically (P < .001); however, there was variability in the grade of injury between the 2 groups. Similarly, patients who sustained grade II injuries returned to sport more quickly (8.70 weeks) than patients who had a grade I (13.04 weeks) or grade III injury (16.50 weeks) (P = .016). The amount of time required to RTS was significantly influenced by the athlete's level of play (16.50 weeks for both high school and college levels; 14.70 weeks for professional level) (P = .018). CONCLUSION: The time to RTS for an athlete who suffers from a turf toe injury is significantly influenced by the severity of injury and the athlete's level of competition. Professional athletes who suffer from turf toe injuries RTS sooner than both high school and college athletes. However, there are a limited number of high-level studies evaluating turf toe injuries in the athletic population. Further research is necessary to clearly define the appropriate treatment and RTS protocols based on sport, position, and level of play.

Operative Outcomes of Grade 3 Turf Toe Injuries in Competitive Football Players.

BACKGROUND: Turf toe is a term used to describe a hyperextension injury to the first metatarsophalangeal joint. Although the vast majority of turf toe injuries can be treated successfully without operative intervention, there are instances where surgery is required to allow the athlete to return to play. Although there is a plethora of literature on turf toe injuries and nonoperative management, there are currently few reports on operative outcomes in athletes. METHODS: We obtained all cases of turf toe repair according to the ICD-10 procedural code. The inclusion criteria included: age greater than 16, turf toe injury requiring operative management and at least a varsity level high school football player. The charts were reviewed for age, BMI, level of competition, injury mechanism, football position, setting of injury and playing surface. In addition, we recorded the specifics of the operative procedure, a listing of all injured structures, the implants used and the great toe range of motion at final follow-up visit. The AOFAS Hallux score and VAS was used postoperatively as our outcome measures. Our patient population included 15 patients. The average follow-up time was 27.5 months. RESULTS: The average patient was 19.3 years old with a body mass index of 32.3. The average playing time missed was 16.5 weeks. The average dorsiflexion range of motion at the final follow-up was 42.3 degrees. At final follow-up, the average AOFAS Hallux score was 91.3. The average VAS pain score was 0.7 at rest and 0.8 with physical activity. CONCLUSION: Complete turf toe injuries are often debilitating and may require operative management to restore a pain-free, stable, and functional forefoot. This study represents the largest cohort of operatively treated grade 3 turf toe injuries in the literature and demonstrates that good clinical outcomes were achieved with operative repair. LEVEL OF EVIDENCE: Level IV, case series.
