Early Return to Play After Intramedullary Screw Fixation of Acute Jones Fractures in Collegiate Athletes: 22-Year Experience

Auditing the Representation of Female Athletes in Sports Medicine Research: Fifth-Metatarsal Fractures

Background

Female representation within athletics has increased as a result of Title IX, rising popularity, demand for equal compensation, and greater participation in multiple sports. Despite this, gender disparities in sports medicine research are apparent. This project serves to review the literature available on fifth-metatarsal fractures and assess the representation of female athletes in current literature.

Methods

We used a standardized protocol to audit the representation of female athletes in sports science and sports medicine research for fifth-metatarsal fractures. Primary factors included population, athletic caliber, menstrual status, research theme, sample of males and females, journal impact factor, and Altmetric score.

Results

Thirty articles met the inclusion criteria. A total of 472 fifth-metatarsal fractures were identified, with 373 of 472 fractures (79%) occurring in males and 99 of 472 (21%) in females. The majority of studies (18/30, 60%) were mixed cohort, followed by 10 male only (33.33%), 1 female only (3.33%), and 1 male vs female (3.33%). Out of 831 total patients in the 18 mixed-cohort studies, 605 of 831 patients (72.8%) were male and 226 of 831 patients (27%) were female. All 18 mixed-sex cohorts investigated health outcomes. Male-only studies evaluated health outcomes and performance metrics. No studies investigated female performance. The one female-only study investigated health outcomes and was the only study to account for menstrual status. There was a single metatarsal fracture in this study population.

Conclusion

Females are underrepresented in research regarding sports science and sports medicine research for fifth-metatarsal fractures. Research focused on female-only fifth-metatarsal fracture studies exploring the potential impact of female sex-specific factors such as menstrual status in study design are needed.

Surgical Management of Jones Fractures in Athletes: Orthobiologic Augmentation: A Systematic Review and Meta-analysis of 718 Fractures

BACKGROUND

The use of orthobiologics is expanding. However, the use of orthobiologic augmentation in primary fracture fixation surgery remains limited. Primary fracture fixation of the fifth metatarsal (Jones) in athletes is one of the rare situations where primary orthobiologic augmentation has been advocated.

PURPOSE

To determine the effect of orthobiologic augmentation on the outcome of surgically managed Jones fractures in athletes.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 2 independent team members searched several databases including PubMed, MEDLINE, Embase, Google Scholar, Web of Science, Cochrane Library, and ClinicalTrials.gov through March 2021 to identify studies reporting on surgically managed Jones fractures of the fifth metatarsal exclusively in athletes. The primary outcomes were the return to play (RTP) rate and time to RTP, whereas the secondary outcomes were time to union, union rate, and refractures. Data were presented by type of treatment (biologically augmented fixation or fixation alone).

RESULTS

In the biologically augmented fixation group, successful RTP was reported in 195 (98.98%) of 197 fractures (odds ratio [OR], 97.5%; 95% CI, 95.8%-100%; I² = 0), with a mean time to RTP of 10.3 weeks (95% CI, 9.5-11.1 weeks; I² = 99%). In the group that received fixation without biological augmentation, successful RTP was reported in 516 (99.04%) of 521 fractures (OR, 98.7%; 95% CI, 97.8%-99.7%; I² = 0], with a mean time to RTP of 9.7 weeks (95% CI, 7.84-11.53 weeks; I² = 98.64%]. In the biologically augmented fixation group, fracture union was achieved in 194 (98.48%) of 197 fractures (OR, 97.6%; 95% CI, 95.5%-99.7%; I² = 0%), with a mean time to fracture union of 9.28 weeks (95% CI, 7.23-11.34 weeks; I² = 98.18%). In the group that received fixation without biological augmentation, fracture union was achieved in 407 (93.78%) of 434 fractures (OR, 97.4%; 95% CI, 96%-98.9%; I² = 0%), with a mean time to fracture union of 8.57 weeks (95% CI, 6.82-10.32 weeks; I² = 98.81%).

CONCLUSION

Orthobiologically augmented surgical fixation of Jones fractures in athletes is becoming increasingly common, despite the lack of comparative studies to support this practice. Biologically augmented fixation of Jones fractures results in higher fracture union rates than fixation alone but similar rates of RTP and time to RTP. Although the current evidence recommends primary surgical fixation for the management of Jones fractures in athletes, further high quality comparative studies are required to establish the indication for orthobiologic augmentation.

Return to Play and Player Performance After Foot Fracture in UEFA Soccer Players

Background:

There is a paucity of information on rate and time to return to play (RTP) in elite-level soccer players who have sustained foot fractures.

Purpose:

To (1) determine the rate and timing of RTP after foot fracture (eg, tarsal, metatarsal, or phalangeal), (2) investigate foot fracture reinjury incidence after RTP, and (3) evaluate performance after foot fracture as compared with matched, uninjured controls.

Study Design:

Descriptive epidemiology study.

Methods:

Athletes sustaining foot fractures were identified across the 5 major European soccer leagues (English Premier League, Bundesliga, La Liga, Ligue 1, and Serie A) between 2000 and 2016. Injured athletes were matched to controls (1:1) using demographic characteristics and performance metrics from 1 season before injury. The authors recorded RTP rate, reinjury incidence, player characteristics associated with RTP within 2 seasons of injury, player availability, field time, and performance metrics during the 4 seasons after injury.

Results:

A total of 192 elite soccer players sustaining a foot fracture were identified; 40 players (20.8%) underwent operative treatment. Athletes missed an average of 69.41 ± 59.43 days and 5.15 ± 23.28 games. In the 4 seasons after injury, 80% of players returned to play, with 72% returning to play within 1 season of injury. Nine players (5%) sustained a subsequent foot fracture. Athletes with a foot fracture demonstrated significantly longer league retention compared with uninjured controls (P < .001). Elite soccer players older than 30 years of age were less likely to RTP (odds ratio, 0.67; P = .002), whereas career experience, field position, and baseline performance showed no significant association with RTP rates. Injured athletes demonstrated similar performance to controls during the 4 years after injury, and there were no position-dependent differences on subgroup analysis. The players who underwent operative treatment had more assists per 90 minutes and more team points per game during the first season after injury compared with athletes treated nonoperatively.

Conclusion:

Foot fractures in elite soccer players resulted in moderate loss of play time (69.41 days). RTP rates were high at 80%, although players older than 30 years of age were less likely to RTP. On RTP, athletes who sustained a foot fracture maintained performance similar to preinjury levels and to uninjured controls.

Fractures of the Base of the Fifth Metatarsal Bone: A Critical Analysis Review

»

Fractures of the proximal fifth metatarsal (PFMT) are one of the most common foot injuries, accounting for 61% to 78% of all foot fractures, but full consensus on their classification, diagnosis, and treatment has not yet been reached.

»

The most commonly accepted classification is that of Lawrence and Botte, who divided the location of PFMT fractures into 3 zones with respect to their healing potential.

»

Avulsion fractures of the tuberosity of the base (zone 1) generally heal well, and nonoperative treatment is commonly recommended.

»

Internal fixation may be considered for displaced fractures that extend into the fourth-fifth intermetatarsal joint (zone 2) as well as for nondisplaced fractures in athletes or high-demand patients, with the aims of reducing the healing time and expediting return to sport or work.

»

Stress fractures of the proximal diaphysis (zone 3) are preferably treated operatively, particularly in the presence of signs of delayed union. With nonoperative treatment, supportive measures such as ultrasonography or external/extracorporeal shockwave therapy have been demonstrated to have limited potential for the enhancement of fracture-healing.

Surgical Management of Proximal Fifth Metatarsal Fractures in Elite Athletes: A Systematic Review

Background

As a result of the high physical demand in sport, elite athletes are particularly prone to fifth metatarsal fractures. These injuries are typically managed surgically to avoid high rates of delayed union and allow for quicker return to play (RTP).

Purpose

To review studies showing clinical and radiographic outcomes, RTP rates, and complication rates after different surgical treatment modalities for fifth metatarsal fractures exclusively in elite-level athletes.

Study Design

Systematic review; Level of evidence, 4.

Methods

A systematic search was conducted within the PubMed, Scopus, and Cochrane databases from January 2000 to January 2020. Inclusion criteria consisted of clinical outcome studies after operative management of fifth metatarsal fractures in elite athletes. Exclusion criteria consisted of nonoperative management, high school or recreational-level athletic participation, nonclinical studies, expert opinions, and case series with <5 patients.

Results

A total of 12 studies met inclusion and exclusion criteria, comprising 280 fifth metatarsal fractures treated surgically. Intramedullary screw fixation was the most common fixation construct (47.9%), and some form of intraoperative adjunctive treatment (calcaneal autograft, iliac crest bone graft, bone marrow aspirate concentrate, demineralized bone matrix) was used in 67% of cases. Radiographic union was achieved in 96.7% of fractures regardless of surgical construct used. The overall mean time to union was 9.19 weeks, with RTP at a mean of 11.15 weeks. The overall reported complication rate was 22.5%, with varying severity of complications. Refracture rates were comparable between the different surgical constructs used, and the overall refracture rate was 8.6%.

Conclusion

Elite athletes appeared to have a high rate of union and reliably returned to the same level of competition after surgical management of fifth metatarsal fractures, irrespective of surgical construct used. Despite this, the overall complication rate was >20%. Specific recommendations for optimal surgical management could not be made based on the heterogeneity of the included studies.

Jones type fifth metatarsal fracture fixation in athletes: A review and current concept

Jones type fifth metatarsal fracture is a common occurrence among athletes at all levels. These fractures may occur due to several mechanisms, but inversions and twisting injuries are considered some of the leading causes in sports. However, while Jones fracture incidences are frequent in the sporting world, there is still a lack of consensus on how such fractures should be effectively managed. There are numerous treatment options for patients with fifth metatarsal Jones fractures. The role of nonoperative treatment remains controversial, with concerns about delayed union and nonunion. Surgical stabilization of metatarsal Jones fractures is therefore often recommended for athletes, as it is often associated with a low number of complications and a higher rate of union than nonoperative management. This review will focus on literature regarding the prevalence of Jones type fifth metatarsal fracture, alongside the efficacy of both conservative and surgical treatment within this population.

Optimizing Return to Play for Common and Controversial Foot and Ankle Sports Injuries

»

Surgical decision-making should consider factors to help optimize return to play for athletes with foot and ankle injuries, including injuries to the syndesmosis, the Achilles tendon, the fifth metatarsal, and the Lisfranc complex. Understanding influential factors on return to play may help orthopaedic surgeons counsel athletes and coaches on expectations for a timeline to return to play and performance metrics.

»

Outcomes after rigid and flexible fixation for syndesmotic injuries are generally favorable. Some data support an earlier return to sport and higher functional scores with flexible fixation, in addition to lower rates of reoperation and a decreased incidence of malreduction, particularly with deltoid repair, if indicated.

»

Minimally invasive techniques for Achilles tendon repair have been shown to have a decreased risk of wound complications. Athletes undergoing Achilles repair should expect to miss a full season of play to recover.

»

Athletes with fifth metatarsal fractures have better return-to-play outcomes with surgical management and can expect a high return-to-play rate within approximately 3 months of surgery.

»

Percutaneous treatment of Lisfranc injuries may expedite return to play relative to open procedures.
