Meta-Analysis
OBJECTIVE
Bone stress injuries (BSIs) are classified in clinical practice as being at low- or high-risk for complication based on the injury location. However, this dichotomous approach has not been sufficiently validated. The purpose of this systematic review was to examine the prognostic role of injury location on return-to-sport (RTS) and treatment complications after BSI of the lower extremity and pelvis.
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
PubMed, Web of Science, Cochrane CENTRAL and Google Scholar databases were searched from database inception to December 2021.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES
Peer-reviewed studies that reported site-specific RTS of BSIs in athletes.
RESULTS
Seventy-six studies reporting on 2974 BSIs were included. Sixteen studies compared multiple injury sites, and most of these studies (n=11) described the anatomical site of injury as being prognostic for RTS or the rate of treatment complication. Pooled data revealed the longest time to RTS for BSIs of the tarsal navicular (127 days; 95% CI 102 to 151 days) and femoral neck (107 days; 95% CI 79 to 135 days) and shortest duration of time for BSIs of the posteromedial tibial shaft (44 days, 95% CI 27 to 61 days) and fibula (56 days; 95% CI 13 to 100 days). Overall, more than 90% of athletes successfully returned to sport. Treatment complication rate was highest in BSIs of the femoral neck, tarsal navicular, anterior tibial shaft and fifth metatarsal; and lowest in the fibula, pubic bone and posteromedial tibial shaft.
CONCLUSION
This systematic review supports that the anatomical site of BSIs influences RTS timelines and the risk of complication. BSIs of the femoral neck, anterior tibial shaft and tarsal navicular are associated with increased rates of complications and more challenging RTS.

BACKGROUND
Metatarsal fractures are among the most common foot and ankle injuries, with an annual incidence of 6.7 per 100 000 persons. Approximately 30% of metatarsal fractures affect the base of the fifth metatarsal bone. Nevertheless, no evidence-based treatment recommendations are available to date.
METHODS
The three fracture localizations according to Lawrence and Botte (zone I, proximal to the intermetatarsal joint between the fourth and fifth metatarsal bones; zone II, in the area of the joint; zone III, at the distal end of the joint) are analyzed on the basis of a systematic literature search. Studies were included that compared the treatment of two types of fracture in the same manner, or that compared two different treatments for a single type of fracture.
RESULTS
Nine studies compared different treatments of zone I fractures. Two of these were randomized controlled trials (RCTs); in one RCT, patients given functional therapy returned to work much sooner than those treated with immobilization (11 vs. 28 days; p = 0.001), with otherwise similar outcomes. The non-randomized studies revealed a faster return to full function (33 vs. 46 days; p<0.05) with early functional therapy, and similar outcomes for immobilization and surgery. One RCT that compared functional therapy with immobilization for zone II fractures revealed no statistically significant difference. Five studies compared fractures in zones I and II that were treated in the same manner, revealing similar outcomes. One RCT compared surgery and immobilization for zone III fractures: surgery led to statistically significant improvement of the outcome in all of the measured parameters.
CONCLUSION
Fractures in zones I and II should be treated with early functional therapy. There seems to be no reason to consider zone I and II fractures as two separate entities, as the outcomes in the two groups are similar. In contrast, fractures in zone III should primarily be treated surgically.

International Journal of Exercise... 2023To evaluate the effectiveness of footwear, foot orthoses and training-related strategies to prevent lower extremity bone stress injury (BSI). (Review)
Review
OBJECTIVE
To evaluate the effectiveness of footwear, foot orthoses and training-related strategies to prevent lower extremity bone stress injury (BSI).
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
Four bibliographic databases (from inception until November 2021): Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and CINAHL.
ELIGIBILITY CRITERIA
Randomised controlled trials (RCTs) that assessed the risk of developing a BSI when using particular footwear, foot orthoses or training-related strategies such as muscle strengthening, stretching, and mechanical loading exercises.
RESULTS
Eleven studies were included in this systematic review. When wearing foot orthoses, the risk ratio of developing a BSI on any lower extremity bone is 0.47 (95% CI 0.26 to 0.87; = 0.02). When doing pre-exercise dynamic stretching, the risk ratio of suffering a tibial BSI is 1.06 (95% CI 0.67 to 1.68; = 0.79). No meta-analyses could be performed for footwear or training-related strategies. The quality of evidence for all these results is low considering the high risk of bias in each study, the low number of studies and the low number of cases in each study.
CONCLUSION
This systematic review reveals the lack of high-quality studies in BSI prevention. Based on studies at high risk of bias, foot orthoses could potentially help prevent BSIs in the military setting. It is still unknown whether footwear and training-related strategies have any benefits. It is crucial to further investigate potential BSI prevention strategies in women and athletes. Research is also needed to assess the influence of running shoes and loading management on BSI incidence.

Foot & Ankle Specialist Jun 2023The aim of this review was to determine operative indications for Lisfranc injuries. (Review)
Review
OBJECTIVE
The aim of this review was to determine operative indications for Lisfranc injuries.
METHODS
A systematic review using a MEDLINE literature search was performed using the index "Lisfranc Injury" from 1980 onward using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines where applicable. Inclusion criteria were all clinical studies reporting on the management of Lisfranc injuries obtained via the search index, including case reports, review articles, cohort studies, and randomized trials. Non-English-language articles, inaccessible articles, those not relevant to the management of Lisfranc injuries (biomechanical, cadaveric, and technique articles), and those that did not explicitly state operative indications (vague or absent indications) were excluded.
RESULTS
After identifying 737 studies, the full text of 391 studies was reviewed, and 58 reports providing explicit operative indications were included in the final analysis. Fifty-one (81.1%) studies provided diastasis cutoffs varying ≥2 mm (35/58; 60.4%), ≥ ≥3 mm (3; 5.2%); the diastasis location was most commonly unspecified (31/58; 53.5%) or varied between combinations of metatarsal, tarsal, cuboid, and cuneiform bones (20/58; 27.6%). Specific imaging criteria for surgery included an avulsion fracture or fleck sign (3/58; 5.2%), arch height loss (3/58; 5.2%), and a tear on magnetic resonance imaging (5; 8.6%). The 11 (19%) studies defining operative indications in terms of classification schemes used the Nunley and Vertullo (8/58; 13.8%), Myerson (2; 3.5%), and Buehren (1; 1.7%) systems. Twenty-one (36.2%) studies provided multiple operative indications.
CONCLUSION
The most common Lisfranc operative indications among the limited reporting studies varied from a 1- to 3-mm diastasis across several locations. It is imperative for operative indications to be reported with an increased frequency and in a homogenous fashion to guide the clinical management of these subtle injuries.

Review
BACKGROUND
Freiberg's disease is an osteonecrosis of the metatarsal head bone. Numerous surgical interventions can be provided; however, the literature is limited in systematic reviews discussing the various options. The study aimed to systematically review the quantity and quality of literatures exploring the surgical interventions.
METHODS
Fifty articles were found to be relevant for assessing the efficacy of common surgical interventions. The articles were assigned a level of evidence (I-V) to assess their quality. Next, the studies were reviewed to provide a grade of recommendation (A-C, I).
RESULTS
Two studies were found at level III that explored osteotomy and autologous transplantation; the other studies were level IV-V. There is poor evidence (grade C) in supporting of joint sparing and joint sacrificing for Freiberg's disease.
CONCLUSION
Poor evidence exists to support the surgical interventions for Freiberg's disease, higher quality trials are needed to support the increasing application of these surgical techniques.

Review
There are various treatment approaches for the subjects with metatarsus adductus, including nonsurgical and surgical treatment. Nonsurgical treatments such as serial casting, modified shoes (Bebax shoe, Ipos antiadductus shoe) and orthoses (Wheaton brace, counter rotation system splint, Denis Brown bar, and Fillauer bar) are widely used in this regard. The main question posted here is which orthoses are more effective in correcting metatarsus adductus. Therefore, the aim of this review was to determine the efficiency of various nonsurgical treatments used for metatarsus adductus. MEDLINE/PubMed, EMBASE, Cochrane Central Register of Controlled Trial, Cochrane Data base of systematic review (CDSR), Scopus and ISI Web of knowledge (from 1960 to 2021) were searched by predefined search strategies to screen eligible randomized controlled studies meeting established criteria. The quality of the studies was assessed based on Down and Black tool. 200 studies on this topic were reviewed and finally 11 studies which met the inclusion criteria were selected for final analysis. These studies evaluated the efficiency of nonsurgical treatment options on foot angle and deformity correction in the subjects with metatarsus adductus. Quality of the papers based on Downs and Black tool varied between 13 and 23. Some treatments such as Wheaton brace, rigid strap, exercise (manipulation), reverse last shoe and plaster cast are used for these subjects. Although good correction can be achieved with use of these treatment methods, some of them have complications which should be considered in this regard. It seems that Wheaton brace and Bebax shoe have fewer complications compared to other methods.

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.

Skeletal Radiology Jan 2020To systematically review current diagnostic imaging options for assessment of the Lisfranc joint.
OBJECTIVES
To systematically review current diagnostic imaging options for assessment of the Lisfranc joint.
MATERIALS AND METHODS
PubMed and ScienceDirect were systematically searched. Thirty articles were subdivided by imaging modality: conventional radiography (17 articles), ultrasonography (six articles), computed tomography (CT) (four articles), and magnetic resonance imaging (MRI) (11 articles). Some articles discussed multiple modalities. The following data were extracted: imaging modality, measurement methods, participant number, sensitivity, specificity, and measurement technique accuracy. Methodological quality was assessed by the QUADAS-2 tool.
RESULTS
Conventional radiography commonly assesses Lisfranc injuries by evaluating the distance between either the first and second metatarsal base (M1-M2) or the medial cuneiform and second metatarsal base (C1-M2) and the congruence between each metatarsal base and its connecting tarsal bone. For ultrasonography, C1-M2 distance and dorsal Lisfranc ligament (DLL) length and thickness are evaluated. CT clarifies tarsometatarsal (TMT) joint alignment and occult fractures obscured on radiographs. Most MRI studies assessed Lisfranc ligament integrity. Overall, included studies show low bias for all domains except patient selection and are applicable to daily practice.
CONCLUSIONS
While conventional radiography can demonstrate frank diastasis at the TMT joints; applying weightbearing can improve the viewer's capacity to detect subtle Lisfranc injury by radiography. Although ultrasonography can evaluate the DLL, its accuracy for diagnosing Lisfranc instability remains unproven. CT is more beneficial than radiography for detecting non-displaced fractures and minimal osseous subluxation. MRI is clearly the best for detecting ligament abnormalities; however, its utility for detecting subtle Lisfranc instability needs further investigation. Overall, the available studies' methodological quality was satisfactory.

Meta-Analysis Review
BACKGROUND
Tailors bunions are common forefoot deformities affecting the fifth MPJ, with challenging symptomatology often resistant to conservative care. Currently no gold standard exists for the surgical management of tailor's bunions, although the scarf osteotomy has been described as a versatile option for reducing these deformities.
METHODS
Relevant electronic databases were searched to collate all studies pertaining to tailors bunion correction using the scarf osteotomy between 2000 and 2021. Both surgeon and patient reported outcomes were required to be included in the systematic review. Methodological quality assessment and risk of bias was performed for each study. Statistical analysis of outcomes and complications was measured. Four small scale case series studies met the inclusion criteria.
RESULTS
All studies demonstrated a statistically significant reduction of 4th inter-metatarsal angles, improvement in clinical and patient reported outcome measures. 15% complication rate was identified, however recurring plantar hyperkeratoses were the most frequent, with one study suggesting a relationship with Pes Cavus. All four studies demonstrated significant methodological short comings and high risk of bias.
CONCLUSION
Scarf osteotomy provides good reduction of tailors' bunion deformities, demonstrates low complication rate and high patient satisfaction. Foot and Ankle surgeons should counsel patients' accordingly on risk of recurrence where hyperkeratosis is a key complaint.

Gait & Posture May 2022Hallux valgus (HV) is a foot deformity characterized by lateral deviation of the big toe and medial deviation of the first metatarsal. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Hallux valgus (HV) is a foot deformity characterized by lateral deviation of the big toe and medial deviation of the first metatarsal.
RESEARCH QUESTION
This study aimed to shed light on the treatment effects of different interventions and surgical procedures for HV deformity to determine the effectiveness of gait biomechanics correction.
METHODS
English-language searches of the electronic databases were conducted in the Cochrane Library, Web of Science, PubMed, Scopus, and Embase. Gait biomechanics evaluation before and after conservative or operative treatments was essential for inclusion in this review. Methodological quality was assessed by the Institute of Health Economics (IHE) quality appraisal tool. All pooled analysis was based on the random-effects model.
RESULTS
Twenty-five articles (1003 participants) were identified in this review. Three studies chose conservative therapies for HV deformity, incorporating foot orthotics and minimalist running intervention, and surgeries were performed in twenty-two studies. For the pressure parameter alteration under the hallux, the effect size (ES) in the conservative treatment subgroup was - 0.95 with 95%CI [- 1.69, - 0.21]. It demonstrated a moderate ES of - 0.44% and 95%CI [- 0.81, - 0.07] in the surgery subgroup. The five operations' peak pressure alteration under the hallux demonstrated a moderate ES of - 0.45% and 95%CI [- 0.54, - 0.36].
SIGNIFICANCE
Both non-operative and operative treatments could achieve the forefoot pressure redistribution, decreasing loading beneath the hallux and first metatarsal regions,However, the treatment effects of surgeries were not very robust. The percutaneous DSTR-Akin technique is recommended as an adequate operative treatment, with a large ES and moderate heterogeneity. The negative gait return effect should be noticed while using Scarf osteotomy, despite positive clinical and radiographic outcomes.
