Meta-Analysis Review
OBJECTIVES
In this review, we discuss the efficacy and safety of biodegradable magnesium screws compared to titanium screws in the treatment of hallux valgus (HV) in patients undergoing distal metatarsal osteotomy (DMO).
MATERIALS AND METHODS
Eligible scientific articles published prior to October 2022 were retrieved from the PubMed, Springer, ScienceDirect, and Cochrane Library databases. The terms used for searching included "hallux valgus", "distal metatarsal osteotomies", and "bioabsorbable magnesium screw" which were limited in the title or abstract through the text. The title and abstract were checked one by one to exclude the non-related studies. For primary identified studies and relevant systematic reviews, the full texts were accessed and browsed to finally include the eligible studies. No restriction was set on publication language and publication status.
RESULTS
Two randomized-controlled trials (RCTs) and three non-RCTs that met the inclusion criteria were included. There was no significant difference in the American Orthopaedic Foot and Ankle Society (AOFAS) score, postoperative HV angle (HVA), intermetatarsal angle (IMA), Visual Analog Scale (VAS) score, soft tissue irritation, implant fracture, reoperation, and infection rates between two groups.
CONCLUSION
Bioabsorbable magnesium compression screws show comparable clinical or radiological results to titanium compression screws in the treatment of HV in patients undergoing DMO.

BACKGROUND
Several procedures and types of osteotomies have been described for hallux valgus (HV) correction. Percutaneous techniques may lead to an early regain of function reducing morbidity and recovery time. In this study, we aimed to evaluate the clinical and radiographic outcomes of percutaneous hallux valgus (HV) correction.
METHODS
One hundred and twenty-four feet treated with the percutaneous technique between May 2011 and December 2015 were included in our study. All patients underwent resection of the medial metatarsal exostosis, complete first metatarsal distal osteotomy, adductor hallucis tendon release and Akin osteotomy of the proximal phalanx. Pre- and postoperative X-rays were clinically assessed.
RESULTS
The mean hallux valgus angle (HVA) and the intermetatarsal angle (IMA) decreased significantly from the preoperative assessment to the final follow-up. The AOFAS score improved from a mean preoperative value of 70.2 to 93.8 at the final follow-up.
CONCLUSION
Percutaneous complete distal osteotomy in hallux valgus correction is a safe, reliable and effective procedure for the correction of symptomatic mild hallux valgus. Nevertheless, it requires appropriate surgical experience and patient aftercare in order to achieve the best result.

Review
The research results are inconsistent that assessing whether the increased obliquity of the distal articular surface of the medial cuneiform leads to an increase in hallux valgus angle. Thus, this study investigated the relationship between distal medial cuneiform obliquity and hallux valgus by measuring various angles in weightbearing anteroposterior radiographs of the foot. In total, 679 feet of 538 patients with the radiographs were included in the study. We measured radiographic parameters including hallux valgus angle, first to second intermetatarsal angle, metatarsus adductus angle, first metatarsus cuneiform angle, distal medial cuneiform angle, and first proximal metatarsal articular angle. The surface morphology (flat or curved) of the first tarsometatarsal joint was also recorded. Our results analysis revealed a weak negative correlation between distal medial cuneiform angle and both hallux valgus angle and first to second intermetatarsal angle, contrary to our assumption. So we believe that distal medial cuneiform angle was relatively constant and it cannot be used as a characteristic angle for quantifying hallux valgus. First metatarsus cuneiform angle was a characteristic indicator of hallux valgus and was positively correlated with its severity (p < .000), indicating that it can be used to measure the size of hallux valgus. It can also be used as a reference factor for the first metatarsal osteotomy in clinical bunion orthopedics. First tarsometatarsal joint morphology was unrelated to hallux valgus, whereas metatarsus adductus angle, and first proximal metatarsal articular angle should be considered in hallux valgus.

PURPOSE OF STUDY
Planovalgus deformity in cerebral palsy is disabling for the child in terms of increased energy expenditure during the gait cycle. The lever arm function of the foot is lost due to midfoot break and the achilles tendon is at a disadvantage being unable to lift the body weight during push-off. We evaluated the results of calcaneal lengthening osteotomy in such patients with clinical, radiological and gait parameters.
METHODS
17 spastic feet in a sample of 10 children were included in our study. The children were classified according to the GMFCS classification system and clinical parameters such as heel valgus and heel rise tests, radiological angles such as Talo-calcaneal angle and Talo-navicular coverage angle on AP view and Calcaneal pitch angle, calcaneus-5th metatarsal angle and talus-1st metatarsal angle on lateral view were measured. Video gait analysis was performed to observe knee progression angle in mid stance and peak knee flexion angle in mid and terminal stance.
RESULTS
Improvement was noted clinically in the heel valgus angle (preop-12.06°, postop-5.12°) and radiological parameters showed an improved coverage of the talus by navicular with simultaneous lifting of the medial longitudinal arch. Gait analysis showed decreased knee flexion trend in mid and terminal stance phase with better restoration of the knee axis.
CONCLUSION
Calcaneal lengthening osteotomy with peroneus brevis lengthening corrects almost all aspects of planovalgus deformity with an improved gait pattern without disturbing joint range of motion. It is a safe procedure for GMFCS grade 1 and 2 patients without much complications.

BACKGROUND
Hallux valgus can alter load bearing in the foot leading to abnormal forces on the second toe. The purpose of this study was to determine demographic and radiographic factors associated with second ray hammertoes in hallux valgus using 3-dimensional weightbearing CT scans.
METHODS
Seventy-one patients who underwent a modified Lapidus procedure for hallux valgus with preoperative weightbearing CT scans were separated into 2 groups: (1) hallux valgus only (47 feet) and (2) hallux valgus with second ray hammertoe (29 feet). Preoperative age, body mass index (BMI), sex, hallux valgus angle (HVA), intermetatarsal angle (IMA), absolute and effective metatarsal (MT) lengths, ratios between metatarsal lengths, Meary angle, metatarsus adductus angle (MAA), and pronation were measured. Mean values of continuous variables were compared and both simple and multivariable logistic regression models were used to evaluate associations between variables and hammertoe occurrence.
RESULTS
Patients in the hammertoe group were found to be significantly older and have higher BMIs, HVAs, effective second MT lengths, IMAs, and more apex plantar Meary angles (all < .05). The multivariable analysis demonstrated that a higher IMA and a more apex plantar Meary angle were the only significant predictors of second ray hammertoe risk ( = .03 and = .01, respectively) once corrected for age and BMI.
CONCLUSION
Significant associations were found between older age, higher BMI, and more severe deformity and the occurrence of hammertoe in hallux valgus patients. These results may help clinicians counsel hallux valgus patients about the risk of developing an advanced hammertoe deformity.

Hallux valgus deformity is a very common pathological condition which commonly produces painful disability. It is characterised as a combined deformity with a malpositioning of the first metatarsophalangeal joint caused by a lateral deviation of the great toe and a medial deviation of the first metatarsal bone.Taking the patient's history and a thorough physical examination are important steps. Anteroposterior and lateral weight-bearing radiographs of the entire foot are crucial for adequate assessment in the treatment of hallux valgus.Non-operative treatment of the hallux valgus cannot correct the deformity. However, insoles and physiotherapy in combination with good footwear can help to control the symptoms.There are many operative techniques for hallux valgus correction. The decision on which surgical technique is used depends on the degree of deformity, the extent of degenerative changes of the first metatarsophalangeal joint and the shape and size of the metatarsal bone and phalangeal deviation. The role of stability of the first tarsometatarsal joint is controversial.Surgical techniques include the modified McBride procedure, distal metatarsal osteotomies, metatarsal shaft osteotomies, the Akin osteotomy, proximal metatarsal osteotomies, the modified Lapidus fusion and the hallux joint fusion. Recently, minimally invasive percutaneous techniques have gained importance and are currently being evaluated more scientifically.Hallux valgus correction is followed by corrective dressings of the great toe post-operatively. Depending on the procedure, partial or full weight-bearing in a post-operative shoe or cast immobilisation is advised. Post-operative radiographs are taken in regular intervals until osseous healing is achieved. Cite this article: Fraissler L, Konrads C, Hoberg M, Rudert M, Walcher M.

BACKGROUND
Few previous studies focused on plantar loading patterns in HV patients with metatarsalgia. Are there any differences in plantar pressure measurements in women with HV with and without metatarsalgia?
METHODS
A prospective matched-cohort study was designed to analyze plantar pressure measurements in women with HV with and without metatarsalgia from January 2017 to December 2019. The inclusion criteria were age over 18 years old, women, diagnosis of HV with metatarsalgia. Control group had the same inclusion criteria, except metatarsalgia. Patient-reported outcomes scores included American Orthopedic Foot and Ankle Society Score (AOFAS), and Visual Analog Scale (VAS). Radiographic data were obtained according to the guidelines of the AOFAS Committee on Angular Measurements. Plantar pressure measurements were performed using a platform.
RESULTS
Forty-seven patients met the inclusion criteria. An age-, BMI-, and hallux valgus angle-matched cohort of 47 patients were also selected. There were no statistically significant differences in demographic data and radiographic assessment. HV with metatarsalgia group showed greater values in peak and mean force, peak and mean pressure, and pressure-time integral under toes and metatarsal heads. These differences reached statistically significant in mean force ( = 0.009) and peak force ( = 0.003) under T1; mean pressure ( = 0.01) and peak pressure ( = 0.04) under T1; and mean force ( = 0.003) under MH1. The binary logistic regression analysis showed mean force under T1 as the most associated plantar pressure measurement with the presence of metatarsalgia. C-statistic was 0.66. Mean force > 35 N had a 70% of sensitivity and a 57% of specificity as a cut-off value for the presence of metatarsalgia.
CONCLUSION
HV patients with metatarsalgia had greater values in plantar pressure measurements. Mean force under T1 could be used as a plantar pressure measurement to predict metatarsalgia.

OBJECTIVE
To describe the anatomical and pathological osteoarticular, muscular and tendinous variations in feet of cadavers with hallux valgus and to correlate them with the degree of radiographic deformity.
METHODS
Dissections and radiographs were conducted in the feet of 22 cadavers with halux valgus, aged between 20 and 70 years. The feet affected were compared with 5 normal feet in order to document the anatomical and pathological, myotendinous and articular variations found.
RESULTS
The extensor hallucis longus and brevis tendons were arched in all degrees of deformity, causing a lateral deviation that forms the arc chord of the metatarsophalangeal angle of the hallux. We also observed a deviation to the plantar face of the abductor muscle tendon and lateral deviation of the flexor hallucis muscle tendon. In the moderate deformities, the medial deviation of the first metatarsal head was observed, sliding out of the sesamoid apparatus, pronation of this head, and formation of medial exostoses. In severe deformities, in addition to all other deformities, we found the extensor hallucis longus tendon with two distal insertions, rather than just one.
CONCLUSION
The anatomical alterations found in the hallux valgus may be related to the degree of radiographic deformity

OBJECTIVES
The issue of performing a hallux valgus operation with the wide-awake local anesthesia with no tourniquet (WALANT) technique has not been evaluated before. The objective of this study was to compare the clinical results of patients who underwent the WALANT technique during hallux valgus operation and patients who underwent the procedure with traditional anesthesia (TA).
PATIENTS AND METHODS
In this cross-sectional, retrospective study, 34 patients (17 males, 17 females; mean age: 46.1±8.3 years; range, 36 to 62 years) who underwent first metatarsal osteotomy with the diagnosis of hallux valgus disease between November 1, 2018, and June 1, 2020, were divided into two groups according to the surgical approach determined by patient choice: the WALANT group and the TA group. Demographic characteristics, Visual Analog Scale (VAS) scores for pain and anxiety, postoperative satisfaction levels, and complications were recorded.
RESULTS
There was no significant difference between the groups in terms of demographic characteristics. The VAS pain score during needle insertion was significantly higher in the WALANT group compared to the TA group (p<0.001). Conversely, the VAS anxiety score was significantly higher in the WALANT group compared to the TA group (p<0.001). The median follow-up time was 5.4 months (interquartile range, 5-6 months).
CONCLUSION
This is the first study demonstrating that adequate anesthetic efficacy can be achieved with the WALANT technique for the hallux valgus operation. Acceptable pain scores can be achieved with this technique, and costs are reduced.

Comparative Study
PURPOSE
This study compared results of distal and proximal metatarsal osteotomy for moderate to severe hallux valgus in terms of radiographic correction and functional outcome.
METHODS
We analyzed 125 moderate to severe hallux valgus surgeries. Patients were divided into two groups. Group 1 underwent distal metatarsal osteotomy, and group 2 underwent proximal metatarsal osteotomy. Patients were interviewed for functional scores before and one year after surgery. The anteroposterior (AP) weight-bearing radiography of the foot was taken before and one year after surgery.
RESULTS
There were no significant differences in pain and function after one year in either group. Both groups experienced significant pain reduction and increase in all functional scores. There was significant improvement of hallux valgus and intermetatarsal angle corrections in group 2. There was less improvement in radiographic correction in group 1.
CONCLUSION
Either distal or proximal metatarsal osteotomy is an appropriate pain-relieving procedure and can increase functional outcome in moderate to severe hallux valgus. However, distal metatarsal osteotomy provides lower correction power.
