Background: Nonunion is one of the most challenging problems in the field of orthopedics. The aim of this study was to perform a systematic review of the literature to evaluate the effectiveness of extracorporeal shockwave therapy (ESWT) in the treatment of nonunion in long bones. Methods: We conducted a search of three databases (PubMed, Scopus, and Web of Science) and found 646 total publications, of which 23 met our inclusion criteria. Results: Out of 1200 total long bone nonunions, 876 (73%) healed after being treated with ESWT. Hypertrophic cases achieved 3-fold higher healing rates when compared to oligotrophic or atrophic cases (p = 0.003). Metatarsal bones were the most receptive to ESWT, achieving a healing rate of 90%, followed by tibiae (75.54%), femurs (66.9%) and humeri (63.9%). Short periods between injury and treatment lead to higher healing rates (p < 0.02). Conversely, 6 months of follow-up after the treatment appears to be too brief to evaluate the full healing potential of the treatment; several studies showed that healing rates continued to increase at follow-ups beyond 6 months after the last ESWT treatment (p < 0.01). Conclusions: ESWT is a promising approach for treating nonunions. At present, a wide range of treatment protocols are used, and more research is needed to determine which protocols are the most effective.

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.

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.

Meta-Analysis Review
The origin of fractures of the fifth metatarsus and Jones fracture is not clear. The goal of this study was to investigate the evidence of anatomical deformities such as metatarsus adductus, hindfoot varus, or pes cavus as risk factors for this pathology. A literature search of records related to the review question was performed screening PubMed/Medline, Embase and Cochrane library databases (last update: May 2020) according to PRISMA guidelines. A meta-analysis was performed using the mean difference of the assessed angles (in patients with the fractures vs controls) as outcome measure to summarize literature findings about metatarsus adductus angle (MAA) indicating forefoot adduction, calcaneal pitch angle (CP) indicating hindfoot cavus and varus deformity and Talo-1 metatarsus angle/Meary's angle (T1MA) for varus alignment. Eight studies were included in the qualitative analysis (296 patients), 5 in the quantitative synthesis (132 patients). The pooled mean difference of MAA between fracture versus control group on a per patient-based analysis was 4.62 (95% CI 1.31-7.92). Statistical heterogeneity among studies was detected (I-Square: 76.1%), likely due to different patient groups and low number of studies. The pooled mean differences of CP and T1MA among fracture group versus controls did not show statistical significance. Despite limited literature data, metatarsus adductus deformity seems to be correlated with higher risk of proximal metatarsal fractures and Jones fracture. A significant relationship between hindfoot varus or pes cavus and these fractures was not demonstrated. Further studies and trials are warranted to shed more lights on this topic.

Review
BACKGROUND
Hallux valgus is a common foot condition with numerous surgical techniques described. Minimally invasive surgery is becoming more popular, with resultant development of suitable fixation devices. The aim of this systematic review was to evaluate the evidence on the use of intramedullary devices in hallux valgus first metatarsal corrective osteotomies, and describe clinical and radiological outcomes, with an overview of techniques and implants used.
METHODS
We searched PubMed, Medline, Embase and EMCare databases, conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Radiological outcomes including the hallux valgus angle (HVA) and intermetatarsal angle (IMA) were recorded, as well as clinical outcome scores and complications. Methodological quality of included studies was assessed using the MINORS score.
RESULTS
Ten studies were included, comprising 696 feet in 745 patients. Data pooling and metanalysis was not possible due to overall low quality of evidence. Four implants were reported (Endolog, ISO Plate, V-Tek Plate, Link Fixator) and used with distal first metatarsal osteotomies, with improvement in HVA, IMA, and clinical outcome scores comparable to other fixation techniques. There were no reported cases of non-union. Complication rates were variable (all cause range of 0-21%) across all studies, with an overall low rate.
CONCLUSION
Intramedullary devices are viable and safe to use for hallux valgus first metatarsal osteotomies, with comparable radiological and functional outcomes to other techniques. Current evidence base is of low methodological quality, therefore high quality studies are required to further evaluate these devices.

BACKGROUND
Children with cerebral palsy are highly likely to develop foot deformities, some of which may require surgical intervention. Hallux valgus is a common forefoot deformity which can cause issues with pain, footwear, orthotic splints and soft tissues. It remains unclear what the optimal surgical treatment is for children with cerebral palsy and hallux valgus deformity.
OBJECTIVE
To systematically review studies reporting the clinical and radiological outcomes of surgical correction of hallux valgus deformity in children with cerebral palsy.
METHODS
A systematic review of studies published in electronic databases (Medline, Embase, Pubmed and Cochrane library) from inception until January 2021. Keywords related to hallux valgus and cerebral palsy were included.
RESULTS
58 studies were identified of which 7 met the criteria for inclusion. 200 feet in 134 patients with a mean age of 13.5 years were included, with a mean follow up period of 43 months. A range of clinical and radiographic outcomes were assessed. A treatment framework for the assessment and management of hallux valgus in children with cerebral palsy based on the published evidence is presented.
CONCLUSION
Non-ambulant children with cerebral palsy with symptomatic hallux valgus should primarily undergo first MTPJ arthrodesis whilst those who are ambulant should undergo first metatarsal osteotomy± soft tissue correction.

Meta-Analysis
BACKGROUND
The fifth metatarsal base avulsion fracture (i.e., Pseudo-Jones fracture) is one of the most common foot fractures. The management of pseudo-Jones fractures could be carried out surgically or conservatively. This systematic review and meta-analysis aimed to provide an update about the efficacy of orthotic removable support compared to short-leg casting for individuals with pseudo-Jones fracture.
METHODS
We searched Embase, Medline, and Cochrane Central register of Controlled Trials (CENTRAL) for randomized controlled trials (RCTs) that compared the clinical outcomes of orthotic removable support and short-leg cast for adult individuals with a fifth metatarsal base avulsion fracture. We used 95% as a confidence level and P <0.05 as a threshold. The standardized mean difference (SMD) was used for the continuous outcomes, and the risk ratio (RR) was used for the dichotomous outcomes.
RESULTS
A total of 6 RCTs incorporating 403 individuals out were deemed eligible. There was no significant difference between orthotic removable support and short-leg casting regarding AOFAS score (standardized mean difference (SMD)= 0.31, 95% CI -0.17 to 0.8), pain on VAS score (SMD= -0.08, 95% CI -0.39 to 0.22), VAS-FA score (SMD= 0.22, 95% CI -0.19 to 0.62) EQ-5D VAS score, and non-union rate (RR=0.37, 95% CI 0.05 to 2.74).
CONCLUSION
The current meta-analysis reveals that there is no difference between orthotic removable support and short-leg casting for the conservative management of individuals sustaining pseudo-Jones fracture.

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.

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.

Lapidus arthrodesis is an established standard procedure to correct various foot surgery problems and hallux limitus, hypermobility of the first ray, hallux abductus valgus, and symptomatic lesser metatarsal. After decades, many fixation methods in the orthopaedic surgery industry have been developed for decreasing complications and improving this technique. The aim of this PRISMA compliant systematic review is to analyse the effectiveness of several lapidus plate systems in foot surgery. We have carried out the first systematic review of the relevant published literature so as to systematically evaluate the scientific knowledge available now on this association, assigning predefined eligibility criteria. Fourteen studies were selected which had an overall of 738 cases. The first tarsal metatarsal joint and hallux valgus were treated by the application of different types of Lapidus plate system. The optimal level of the fixation in these procedures is related with the type and system insertion place of the plate with or without screw in each specific foot disease. There is an insufficient number of studies about the effectiveness of the different types of Lapidus plate system in foot surgery, and there is a need to increase outcomes knowledge on the level of the fixation, sort of the system, and insert place in foot surgery.
