Project description:BackgroundCurrently, more than 150 surgical techniques have been described for the treatment of hallux valgus. The abundance of techniques indicates that there is no technique that has been designated as a gold standard. In recent years, a particular interest in the use of minimally invasive techniques has grown. The aim of this study was to prospectively compare clinical, radiologic, and postoperative outcomes between the MICA technique and open chevron technique over a 1-year follow-up period.MethodsBetween January 2016 and August 2020, data were prospectively collected from consecutive patients preoperatively and at 6 weeks, 3 months, and 12 months following minimally invasive chevron and Akin (MICA) or open chevron osteotomies. Radiographic outcomes were measured using weightbearing radiographs preoperatively and at 3 and 12 months postoperatively. Clinical outcomes were measured using the American Orthopaedic Foot & Ankle Society (AOFAS), Manchester-Oxford Foot Questionnaire (MOXFQ), VAS (visual analog scale), Foot Function Index (FFI), Foot and Ankle Outcome Score (FAOS), and Euro-QoL-5D (EQ5D) questionnaires.ResultsOf the 68 patients, 42 patients (62%) underwent a MICA surgery and 26 patients (38%) underwent open chevron osteotomy. Both groups showed significant improvement in HVA, IMA, and DMAA at the 1-year follow-up. Our findings show that both clinical and radiologic outcomes of the MICA technique are comparable to the conventional open technique. No significant differences were found in clinical outcomes (VAS, AOFAS, MOXFQ, FFI, and FAOS), complication rate, and operative times.ConclusionThese results show that MICA is a safe alternative for chevron osteotomy. The clinical and radiologic outcomes of these 2 techniques by 12 months are comparable.Level of evidenceLevel II, prospective cohort study.

Project description:BackgroundDistal chevron metatarsal osteotomy (DCO) is a common technique to address hallux valgus (HV), which involves coronal translation of the capital fragment resulting in a nonanatomic first metatarsal. The purpose of this study was to evaluate the radiographic effect of the DCO on the anatomic vs the mechanical axis of the first metatarsal. Our hypothesis was that patients undergoing DCO would have improvement in the mechanical metatarsal axis but worsening of the anatomic axis.MethodsThis was a retrospective case series of consecutive patients who underwent DCO for HV. The primary outcomes were the change in anatomic first-second intermetatarsal angle (a1-2IMA) vs mechanical first-second intermetatarsal angle (m1-2IMA). Secondary outcomes included the change in hallux valgus angle (HVA) and medial sesamoid position.Results40 feet were analyzed with a mean follow-up of 21.2 weeks. The a1-2IMA increased significantly (mean, 4.1 degrees) whereas the m1-2IMA decreased significantly (mean, 4.6 degrees) following DCO. There was a significant improvement in HVA (mean, 12.5 degrees). Medial sesamoid position was improved in 21 feet (52.5%). Patients with no improvement in sesamoid position were found to have a larger increase in a1-2IMA (mean, 4.7 vs 3.5 degrees, P = .03) and less improvement in m1-2IMA (mean, 3.8 vs 5.2 degrees, P = .02) compared to patients with improvement in sesamoid position.ConclusionDistal chevron osteotomy for HV was associated with worsening of the anatomic axis of the first metatarsal despite improvements in the mechanical metatarsal axis, HVA, and medial sesamoid position. Greater worsening of the anatomic axis was associated with less improvement of sesamoid position. Our findings may suggest the presence of intermetatarsal instability, which could limit the power of DCO in HV correction for more severe deformities and provide a mechanism for HV recurrence.Level of evidenceLevel IV, retrospective case series.

Project description:BackgroundAlthough the etiology of hallux valgus is contested, in some patients it may be failure of the stabilizing soft tissue structures around the first ray of the foot. Because there is lack of effective soft tissue techniques, osteotomies have become the mainstream surgical approach to compensate for the underlying soft tissue deficiency; osteodesis, a soft tissue nonosteotomy technique, may be a third alternative, but its efficacy is unknown.Questions/purposesWe asked: (1) Can an osteodesis, a distal soft tissue technique, correct hallux valgus satisfactorily in terms of deformity correction and improvement in American Orthopaedic Foot and Ankle Society (AOFAS) score? (2) Is the effectiveness of an osteodesis affected by the patient's age or deformity severity? (3) What complications are associated with this procedure?MethodsBetween February and October 2010, we performed 126 operations to correct hallux valgus, of which 126 (100%) were osteodeses. Sixty-one patients (110 procedures) (87% of the total number of hallux valgus procedures) were available for followup at a minimum of 12 months (mean, 23 months; range, 12-38 months). This group formed our study cohort. During the study period, the general indications for this approach included failed conservative measures for pain relief and metatarsophalangeal angle greater than 20° or intermetatarsal angle greater than 9°. Intermetatarsal cerclage sutures were used to realign the first metatarsal and postoperative fibrosis was induced surgically between the first and second metatarsals to maintain its alignment. The radiologic first intermetatarsal angle, metatarsophalangeal angle, and medial sesamoid position were measured by Hardy and Clapham's methods for deformity and correction evaluation. Clinical results were assessed by the AOFAS score.ResultsThe intermetatarsal angle was improved from a preoperative mean of 14° to 7° (p<0.001; Cohen's d=1.8) at followup, the metatarsophalangeal angle from 31° to 18° (p<0.001; Cohen's d=3.1), the medial sesamoid position from position 6 to 3 (p<0.001; Cohen's d=2.4), and AOFAS hallux score from 68 to 96 points (p<0.001). Neither patient age nor deformity severity affected the effectiveness of the osteodesis in correcting all three radiologic parameters; however, the deformities treated in this series generally were mild to moderate (mean intermetatarsal angle, 14°; range, 9°-22°). There were six stress fractures of the second metatarsal (5%), five temporary metatarsophalangeal joint medial subluxations all resolved in one month by the taping-reduction method without surgery, and six metatarsophalangeal joints with reduced dorsiflexion less than 60°.ConclusionsThe osteodesis is a soft tissue nonosteotomy technique, and provided adequate deformity correction and improvement in AOFAS scores for patients with mild to moderate hallux valgus deformities, although a small number of the patients had postoperative stress fractures of the second ray develop. Future prospective studies should compare this technique with osteotomy techniques in terms of effectiveness of the correction, restoration of hallux function, complications, and long-term recurrence.Level of evidenceLevel IV, therapeutic study.

Project description:BackgroundWhile proximal first metatarsal osteotomy combined with distal soft tissue realignment is accepted as standard treatment of moderate to severe hallux valgus with metatarsus primus varus, none of the described proximal metatarsal osteotomies address the hyper-obliquity of the first metatarsocuneiform joint. An opening-wedge osteotomy of the medial cuneiform can potentially correct the 1-2 intermetatarsal angle (IMA) in addition to normalizing the hyper-obliquity of the first tarsometatarsal (TMT) joint. The purpose of this study was to retrospectively review the early radiographic and clinical results of the use of a medial cuneiform opening-wedge osteotomy fixed with a low-profile wedge plate combined with distal soft tissue realignment for the treatment of hallux valgus.MethodsFourteen feet (13 patients; 2 male and 11 female, average age 56 years, range 22-75) with hallux valgus underwent an opening-wedge osteotomy of the medial cuneiform fixed with a low-profile nonlocking wedge plate combined with distal soft tissue realignment. The mean preoperative hallux valgus angle (HVA) was 32 degrees and the IMA was 16 degrees. HVA, 1-2 IMA, proximal first metatarsal inclination (PFMI), and presence of osteoarthritis of the first TMT joint were assessed on preoperative and final postoperative radiographs. Final postoperative radiographs were also evaluated for radiographic union and hardware failure at an average of 7 months (range, 3-19 months) postoperatively.ResultsA mean intraoperative correction of 19 degrees and 7 degrees was achieved for the HVA and IMA, respectively. The mean HVA was 22 degrees and the mean IMA was 11 degrees at the time of final follow-up. At final follow-up, a recurrence of the deformity was observed in 12/14 feet. There were 2 nonunions-one plate failure and one screw failure. No first TMT joint instability or arthritis was observed. All patients were ambulatory without assistive device in either fashionable or comfortable shoe wear.ConclusionMedial cuneiform opening-wedge osteotomy resulted in unreliable correction of HVA and IMA at short-term follow-up with a high rate of early recurrence of hallux valgus deformity and a complication rate similar to that of the Lapidus procedure. This procedure cannot be recommended for addressing hallux valgus in the setting of increased obliquity of the first TMT joint.Level of evidenceLevel IV, case series.

Project description:Hallux valgus is a common condition that results from a complex positional deformity of the first ray. The bunion or medial prominence that results from the lateral deviation and pronation of the hallux is only one component of the 3-dimensional deformity. Hallux valgus can lead to considerable pain and altered joint mechanics. The precise biomechanical etiology remains under debate. Predisposing factors include female sex, age, constricting footwear, and family history. Metatarsus adductus, equinus contracture, hammertoe deformity, and pes planus often coexist with hallux valgus. Nonoperative treatment involves patient education, shoe modifications, toe pads and positioning devices, and activity modifications. Surgery is considered in patients who fail nonoperative treatment with the goal of pain relief, correction of the deformity, improved first ray stability, and improved quality of life. More than 100 different procedures have been described to treat hallux valgus; they include combinations of soft tissue balancing, metatarsal osteotomies, and fusion of either the metatarsophalangeal (MTP) or tarsometatarsal (TMT) joint. The choice of procedures depends on the severity and location of the deformity as well as surgeon preference. Recent advances in operative techniques include minimally invasive surgery and correction of rotational deformity.

Project description:BackgroundThe proximal opening wedge osteotomy (POWO) of the first metatarsal (TMT-1) is commonly performed in the operative treatment of hallux valgus. Limited work has been dedicated to study POWO's effect on the TMT-1 joint, however. The purpose of this study is to evaluate the changes in TMT-1 joint contact stress following POWO of the first metatarsal.MethodsFive fresh-frozen cadaveric below-knee specimens (mean age: 73 years) with hallux valgus deformities (mean hallux valgus angle [HVA]: 37.4 ± 8.5 degrees) were studied. The specimens were loaded to 400 N on an MTS servohydraulic load frame. Joint contact characteristics at TMT-1 joint were measured with a Tekscan pressure sensor (Model 6900, 1100 psi; Tekscan Inc, Boston, MA) with various opening wedge sizes of 3, 5, and 7 mm both without and with a distal soft tissue release (DSTR). The contact force, area, and peak contact stress were compared among groups using analysis of variance and post hoc multiple comparisons over the untreated (Dunnett test, P < .05).ResultsThe mean contact force was 47.7 ± 33.5 N for untreated specimens. This increased sequentially with opening wedge size and reached statistical significance for 7-mm opening wedge (129.7 ± 62.3 N, P = .01) and 7-mm wedge + DSTR (134.8 ± 60.5 N, P = .008). The mean peak contact stress was 2.8 ± 1.3 MPa for the untreated specimens and increased incrementally with wedge size to 5.7 ± 3.0 MPa for 7-mm wedge only (P = .03) and 5.6 ± 2.5 MPa for 7-mm wedge + DSTR (P = .05). The contact area increased with corrections, but none reached significance.ConclusionWith increasing opening wedge size, loading of the TMT-1 joint increases. Joint stresses higher than 4.7 MPa have been shown to be chondrotoxic, potentially predisposing patients to arthritic joint changes following POWO.Level of evidenceXXXXXX.

Project description:The underlying reason for recurrence of hallux valgus deformity after bunion surgery is multifactorial and includes surgeon-based and patient-based factors as well as original components of deformity initially unaddressed at the index procedure. Surgical treatment of a recurred hallux valgus deformity should be undertaken using the same guidelines for correction of a primary hallux valgus deformity. It requires correction of bony alignment, restoration of joint congruity, and achievement of soft tissue balance. The purpose of this Technical Note is to describe the details of endoscopic soft tissue procedure to correct a recurred hallux valgus deformity. To successfully complete this procedure, adequate lateral release to achieve soft tissue balance around the first metatarsophalangeal joint with reduction of the sesamoid bones is mandatory.

Project description:ObjectiveHallux valgus (HV) is a common foot deformity, and recurrence is one of the most serious complications after HV correction. As a result, the surgical technique with a lower recurrence rate is a dream. The purpose of the article should be to observe the correction effect of hallux valgus using a novel "V-cut" osteotomy on the first metatarsal head combined with fixation in mortise-shaped bone groove-plasty technique.MethodsTwenty-three consecutive patients (40 feet) with HV were included from March 2019 to May 2020, who were all treated using single screw fixation with V-cut osteotomy on the first metatarsal head combined with mortise-shaped metatarsal bone groove-plasty and Akin osteotomy on the first toe for hallux valgus correction. With a mean follow-up time of 21.7 months, the visual analogue scale (VAS) score and American Orthopedic Foot and Ankle Society (AOFAS) forefoot score and the changes of the hallux valgus angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA) were evaluated during the clinical follow-up. The paired t test was used for analytical statistics.ResultsThe VAS score improved from 6.78 ± 1.74 to 1.87 ± 1.45 and the AOFAS score improved from 53.9 ± 12.3 preoperatively to 94.7 ± 6.8 in the latest follow-up postoperatively (P < 0.01). Besides, the HVA improved from 30.0 ± 6.1° to 5.7 ± 2.8° (P < 0.01); the IMA changed from 13.1 ± 2.8° into 3.3 ± 1.6° (P < 0.01); and the DMAA ameliorated from 27.0 ± 8.4° to 5.9 ± 3.5° (P < 0.01). Only five toes had slight numbness and stiffness in early postoperative period, and these symptoms disappeared completely at 6 months after the surgery. Only one foot was corrected to excess. One screw stern protruding beneath the skin happened, which needed secondary screw removal under local anesthesia.ConclusionsSingle screw fixation with V-cut osteotomy on the first metatarsal head combined with fixation in mortise-shaped metatarsal bone groove-plasty and Akin osteotomy on the first toe is an effective way with low recurrence rate for HV correction.

Project description:BackgroundCorrective surgery for hallux abducto valgus is one of the most performed elective procedures in foot and ankle practice. Numerous methods of surgical correction have been reported within the literature, with varying clinical and patient reported outcomes. This study reviews the patient experience and outcomes in five podiatric surgery centres using the scarf diaphyseal osteotomy.MethodPatient reported outcome measures (PROMs) were captured using the Patient Satisfaction Questionnaire 10 (PSQ-10), part of the PASCOM-10 podiatric surgery audit tool. PROMs were collated across five hospital sites over a 10-year period.ResultsOf 1351 patients reported during the period, 1189 had complete retrospective data. The most common patient aim of surgery was 'no/less pain' reported in 70% of patients. 96.8% of patients reported their original foot complaint as 'better' or 'much better' after surgery. 92.8% of patients reported their expectations had been met with 96.6% reporting they would have surgery again under the same conditions. 98.5% of patients noted that the risks, complications, and expectations had been discussed prior to surgery. The most common complication was metatarsal fracture (4.6%).ConclusionThe scarf osteotomy (with or without an Akin phalangeal osteotomy) consistently showed high patient satisfaction with low complication rates using PSQ-10 and this information can be used as part of the pre-operative consenting process. Patient expectations for surgery were often achieved, which may be attributed to the pre-operative work up of the patient. Further investigation into this correlation is suggested.Level of clinical evidenceIV (retrospective review).

Project description:This systematic review and meta-analysis addresses the effects of minimally invasive surgical techniques, specifically the Reverdin Isham osteotomy, on functional and radiological outcomes in patients with moderate Hallux Valgus, a common foot deformity. The review included randomized and non-randomized controlled trials, as well as case reports, assessing the osteotomy in adults with moderate to severe Hallux Valgus. Searches were conducted in electronic databases such as MEDLINE and Web of Science up until July 2023, and the Joanna Briggs Institute's critical appraisal tool was used to assess the risk of bias. Meta-analytical analyses employed a random-effects model with small-sample correction, presenting results as standardized mean differences and mean differences with 95% confidence intervals. Seven studies involving 554 patients and 643 operated feet were included, showing significant improvements in AOFAS scores (an average improvement of 36 points from 28.61 to 45.16) and reductions in radiological angles such as the distal metatarsal angle and hallux valgus angle post-surgery (IMA improved by - 3.07° from - 4.68 to - 1.46, DMAA by - 6.12° from - 9.52 to - 2.71, and HVangle by - 15.27° from - 17.98 to - 12.57). Despite these positive outcomes, most studies exhibited risks of bias and other methodological limitations, impacting the generalizability of the results. Overall, the findings highlight the efficacy of the Reverdin Isham osteotomy in improving both functional and radiological parameters in patients with moderate Hallux Valgus, although further research is warranted to solidify these results. No specific funding was received for this study, and the protocol was registered on PROSPERO with the number CRD-42023445886.
