Review
BACKGROUND
The current minimally invasive distal metatarsal osteotomy for hallux valgus (HV) is V-shaped, which prevents the correction of the rotational metatarsal head deformity and reduction of the sesamoid bones. We sought to determine the optimal method for sesamoid bone reduction during HV surgery.
METHODS
We reviewed the medical records of 53 patients who underwent HV surgery between 2017 and 2019 using one of three techniques: open chevron osteotomy (n = 19), minimally invasive V-shaped osteotomy (n = 18), and a modified straight minimally invasive osteotomy (n = 16). The sesamoid position was graded using the Hardy and Clapham method on weight-bearing radiographs.
RESULTS
When compared to open chevron and V-shaped osteotomies, the modified osteotomy resulted in significantly lower postoperative sesamoid position scores (3.74 ± 1.48, 4.61 ± 1.09, and 1.44 ± 0.81, respectively, P < 0.001). Furthermore, the mean change in postoperative sesamoid position score was greater (P < 0.001).
CONCLUSION
The modified minimally invasive osteotomy was superior to the other two techniques in correcting HV deformity in all planes, including sesamoid reduction.

PURPOSE
The mobility of the first tarsometatarsal (TMT1) is said to be correlated to the severity of hallux valgus determined using both clinical and radiographic criteria. The sagittal mobility of the TMT1 joint can be evaluated objectively using a new ultrasound test, which quantifies it in the form of a unitless value (ratio of two measurements). The objective of this study was to describe the relationship between TMT1 mobility on an ultrasound test and hallux valgus severity. Hypothesis TMT1 joint mobility increases with hallux valgus severity.
PATIENTS AND METHODS
Forty-nine feet were included that were being treated for isolated hallux valgus and had no evidence of TMT1 hypermobility based on the dorsal drawer test. For each foot, the presence and intensity of load transfer (LT), the intermetatarsal angle (IMA), and the hallux valgus angle (HVA) were determined. Lastly, TMT1 mobility was evaluated with the ultrasound test.
RESULTS
Clinically, no LT was present in 20 feet; it was present only under M2 in 20 feet and reached at least M3 in the other nine feet. The mean IMA on radiographs was 14.6° and the mean HVA was 34.5°. The value of the ultrasound test was significantly different between the three groups of clinical hallux valgus severity: 1.17 with no LT, 1.31 with isolated M2 LT, and 1.72 when LT was at least at M3. Furthermore, this value was correlated with the IMA but not the HVA.
DISCUSSION
This study revealed a relationship between increased TMT1 mobility and hallux valgus severity based on clinical (LT) and radiographic (IMA) criteria. Thus, our working hypothesis is confirmed. However, there was no correlation between TMT1 mobility and HVA suggesting that this angle is less relevant for determining the severity of the condition. This is consistent with the classical pathophysiological concept of metatarsus primus varus where the hallux valgus originates in a metatarsus varus in the tarsometatarsal area.
CONCLUSION
The severity of hallux valgus is correlated with increased mobility of the TMT1 joint, which appears to have a causal role in this condition.

Fourth-Generation Minimally Invasive Hallux Valgus Surgery With Metaphyseal Extra-Articular Transverse and Akin Osteotomy (META): 12 Month Clinical and Radiologic Results.
BACKGROUND
Fourth-generation minimally invasive surgery (MIS) includes the multiplanar rotational deformity correction achieved through manipulation of an extra-articular distal first metatarsal osteotomy that is held with rigid fixation using 2 fully threaded screws, of which one must be bicortical to provide rotational and biomechanical stability. The aim of this study is to report the clinical and radiologic outcomes of an evolved fourth-generation MIS hallux valgus technique.
METHODS
A prospective single-surgeon series of consecutive patients undergoing fourth-generation MIS was performed using a distal transverse osteotomy with a minimum 12-month follow-up. The primary outcome was the Manchester-Oxford Foot Questionnaire (MOXFQ), a validated clinical patient-reported outcome measure (PROM). Secondary outcomes included radiographic deformity correction, clinical assessment, and EuroQol-5D-5L PROMs.
RESULTS
Between September 2019 and June 2021, 50 feet underwent fourth-generation MIS. The mean age was 55.8±15.3 years with a mean follow-up of 1.4 years. Preoperative and minimum 12-month primary outcome data were available for 100% of feet. There was a significant improvement in all MOXFQ domain scores, with the index domain improving from 53.4 to 13.1 ( < .001). There was a significant improvement ( < .001) in hallux valgus angle (32.7 to 7.9 degrees), intermetatarsal angle (14.0 to 4.2 degrees) and distal metatarsal articular angle (18.5 to 5.6 degrees). There was a significant improvement in general health-related quality of life EQ-5D-5L index and EQ-VAS scores ( < .05).
CONCLUSION
The fourth-generation MIS technique is a safe and effective approach to hallux valgus deformity correction with significant improvement in clinical and radiographic outcomes.

BACKGROUND
The purpose of this study was to determine if a postoperative decrease in first metatarsal pronation on 3-dimensional imaging was associated with changes in patient-reported outcomes as measured by the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function, pain interference, and pain intensity domains or recurrence rates in patients with hallux valgus (HV) who undergo a first tarsometatarsal fusion (modified Lapidus procedure).
METHODS
Thirty-nine consecutive HV patients who met the inclusion criteria and underwent a modified Lapidus procedure had preoperative and ≥2-year postoperative PROMIS scores and had first metatarsal pronation measured on preoperative and at least 5-month postoperative weightbearing CT scans were included. Multivariable regression analyses were used to investigate differences in the change in PROMIS domains preoperatively and 2 years postoperatively between patients with "no change/increased first metatarsal pronation" and "decreased first metatarsal pronation." A log-binomial regression analysis was performed to identify if a decrease in first metatarsal pronation was associated with recurrence of the HV deformity.
RESULTS
The decreased first metatarsal pronation group had a significantly greater improvement in the PROMIS physical function scale by 7.2 points ( = .007) compared with the no change/increased first metatarsal pronation group. Recurrence rates were significantly lower in the decreased first metatarsal pronation group when compared to the no change/increased first metatarsal pronation group (risk ratio 0.25, = .025).
CONCLUSION
Detailed review of this limited cohort of patients who underwent a modified Lapidus procedure suggests that the rotational component of the HV deformity may play an important role in outcomes and recurrence rates following the modified Lapidus procedure.

The use of bioabsorbable magnesium (Mg) screws is new in foot surgery. Their relative merit over conventional titanium screws has not yet been proven. This prospective case series study was conducted to compare the clinical and radiological outcomes of bioabsorbable Mg screws and titanium screws. A consecutive series of patients (n = 60; 11 men and 49 women) underwent corrective hallux valgus surgery. The minimum follow-up period was 1 year. The assessment was based on a patient questionnaire, including the American Orthopedic Foot and Ankle Society (AOFAS) hallux valgus score, visual analog scale, patient's global impression of change (PGIC), and fifth metatarsus circumference (IF5C). The radiographic assessment included the intermetatarsal and hallux valgus angles, as well as time to osteotomy union and hardware failure. At 1 year, similar results were obtained radiographically. The healing of the osteotomies was significantly faster in the Mg group. Hardware failure was common in the Mg group (5/26) than in the TI group (0/34) but hardware removal was more common in the TI group (6/34) versus the MG group (0/26). IF5C increased by 8 ± 2 mm in the Mg group. The AOFAS and PGIC scores at 6 months were similar. Validated foot scores and radiographic analysis indicated that there was no detectable difference between the groups. The fast achievement of osteotomy union compensates for a high rate of hardware failure, resulting in patient satisfaction and avoiding reoperation for hardware removal.

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.

Review
BACKGROUND
Among the numerous surgical interventions for correcting hallux valgus deformity in skeletally immature patients, hemiepiphysiodesis is a simple technique with a low complication rate yet its effectiveness remains unclear. This systematic review evaluates hemiepiphysiodesis of the first metatarsal for treating juvenile hallux valgus (JHV) deformities with respect to radiological outcomes, postoperative clinical outcomes, and postoperative complications.
METHODS
EMBASE, MEDLINE, PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) database were searched from inception to September 15th, 2022, for studies investigating hemiepephysiodesis for JHV and its effect on clinical and radiological outcomes. The search, data extraction and methodologic assessment were performed in duplicate for all included studies.
RESULTS
Six studies out of 488 with a total of 147 feet in 85 patients were included in the final qualitative synthesis. The American Orthopaedic Foot & Ankle Society hallux metatarsophalangeal interphalangeal scale (AOFAS Hallux MTP-IP scale) was used in two studies. The mean pooled preoperative score was 62.2 ± 8.9 and improved to 88.6 ± 4.8 postoperatively in 33 patients. All six studies reported significant improvement in the hallux valgus angle (HVA) from mean preoperative angle of 29.2° ± 3.7-23.8° ± 4.5° postoperatively, while the intermetatarsal angle (IMA) preoperative and postoperative means corrected from 13.9° ± 1.1-11.4° ± 1.2°, respectively. Out of 147 feet, 21 (14.2%) had reported complications including recurrence and need for revision surgery.
CONCLUSION
This systematic review confirms that hemiepiphysiodesis of the first metatarsal in patients with JHV has improved clinical and radiological outcomes.

. Bunionette is a deformity of the fifth metatarsal in which there is a painful lateral bony prominence of the distal region of this bone caused by various anatomical and biomechanical changes. The aim of this study is to report on a minimally invasive technique without the use of hardware to treat these deformities. . This is a case series of 18 patients, 25 feet, who underwent bunionette percutaneous surgical treatment. All patients answered the American Orthopaedic Foot and Ankle Society (AOFAS) scale and the visual analogue pain scale (VAS) preoperatively and at the last follow-up. Standard radiological evaluation included measurement of intermetatarsal (4-5 IMA) and fifth toe metatarsophalangeal (5-MTTP) angles. Time to radiographic consolidation, complications, and satisfaction rate were also documented. . The average follow-up was 15.9 months, the AOFAS increased from 49.6 to 92.4 and the VAS decreased from 7.7 to 1.2. It was observed that average 5-MTTP decreased from 15° to 2.7° and that 4-5-IMA decreased from 9.1° to 3.3°. These outcomes showed a statistically significant difference ( < .001). The most common observed complication was the formation of a hypertrophic bone callus in the third postoperative month in three operated feet (12%). One patient had algodystrophy, which improved after conservative treatment. There were no cases of infection, neuropraxis, or recurrences. Fifteen patients rated the result as excellent, 2 as good, and 2 as regular. . Percutaneous osteotomy of the fifth metatarsal without the use of hardware is a safe, reproducible technique and presents good clinical and radiographic results for the treatment of bunionette.

Gait & Posture Oct 2021Hallux valgus orthoses are available in a wide range of designs and materials, but the effects of their design on functional performance have not been fully investigated.
BACKGROUND
Hallux valgus orthoses are available in a wide range of designs and materials, but the effects of their design on functional performance have not been fully investigated.
RESEARCH QUESTION
This present study aims to comprehensively analyze the immediate effects of soft and semi-rigid hallux valgus orthoses on balance, plantar pressure, hallux valgus angle, and subjective sensations.
METHODS
Sixteen female subjects have participated in the study, including 10 subjects with healthy feet and 6 with hallux valgus. Three conditions are tested, including in the barefoot and using two types of commercially available hallux valgus orthoses. The subjects participate in static and dynamic (walking) tests with the use of the Novel Pedar® system. The peak pressure values in the hallux, lateral toes, first metatarsophalangeal joint, 2-4th metatarsal heads, 5th metatarsal head, medial midfoot, lateral midfoot and rearfoot in the various foot conditions are examined and compared. The hallux valgus angle of each subject is measured based on their footprint. Their subjective feelings towards the orthoses are also evaluated. A repeated-measures analysis of variance, and independent-sample t-test are performed.
RESULTS
The correction of the hallux valgus angle is statistically significant when the subjects with hallux valgus use the orthoses. In comparing the two types of orthoses, the use of the orthosis made of soft materials results in correction in the hallux valgus angle and higher wear comfort, and lower plantar pressure in hallux area.
SIGNIFICANCE
The results provide insights into the design of hallux valgus orthoses, thus offering practical reference for the selection of hallux valgus orthosis with compromise between functional performance and wear comfort.

Review
Two theories exist in the development of central or transfer metatarsalgia. First, as the severity of hallux valgus increases, there is mechanical overload of the second metatarsal. Second, increased relative lesser metatarsal length is thought to contribute to metatarsalgia. It is imperative, in the treatment of first ray disorders (hallux valgus or hallux rigidus), to not overshorten the first ray when addressing the first ray pathologic condition. Treatment of metatarsalgia in the setting of failed hallux valgus correction can be treated with both conservative and surgical options.
