Introduction. Recurrence after surgical correction of hallux valgus may be related to coronal rotation of the first metatarsal. The scarf osteotomy is a commonly used procedure for correcting hallux valgus but has limited ability to correct rotation. Using weightbearing computed tomography (WBCT), we aimed to measure the coronal rotation of the first metatarsal before and after a scarf osteotomy, and correlate these to clinical outcome scores. Methods. We retrospectively analyzed 16 feet (15 patients) who had a WBCT before and after scarf osteotomy for hallux valgus correction. On both scans, hallux valgus angle (HVA), intermetatarsal angle, and anteroposterior/lateral talus-first metatarsal angle were measured using digitally reconstructed radiographs. Metatarsal pronation (MPA), alpha angle, sesamoid rotation angle and sesamoid position was measured on standardized coronal CT slices. Preoperative and postoperative(12 months) clinical outcome scores(MOxFQ and VAS) were captured. Results. Mean HVA was 28.6±10.1 degrees preoperatively and 12.1±7.7 degrees postoperatively. Mean IMA was 13.7±3.8 degrees preoperatively and 7.5±3.0 degrees postoperatively. Before and after surgery, there were no significant differences in MPA (11.4±7.7 and 11.4±9.9 degrees, respectively; p = 0.75) or alpha angle (10.9±8.0 and 10.7±13.1 degrees, respectively; p = 0.83). There were significant improvements in SRA (26.4±10.2 and 15.7±10.2 degrees, respectively; p = 0.03) and sesamoid position (1.4±1.0 and 0.6±0.6, respectively; p = 0.04) after a scarf osteotomy. There were significant improvements in all outcome scores after surgery. Poorer outcome scores correlated with greater postoperative MPA and alpha angles (r= 0.76 (p = 0.02) and 0.67 (p = 0.03), respectively). Conclusion. A scarf osteotomy does not correct first metatarsal coronal rotation, and worse outcomes are linked to greater metatarsal rotation. Rotation of the metatarsal needs to be measured and considered when planning hallux valgus surgery. Further work is needed to compare postoperative outcomes with rotational osteotomies and modified Lapidus procedures when addressing rotation

Introduction. Hallux valgus surgical correction has a variable but significant risk of recurrence. Symptoms result from an iatrogenic first brachymetatarsia following the index surgical procedure. First metatarsal shortening has been shown to correlate with the onset of transfer metatarsalgia. We describe the use of the scarf osteotomy to both correct the recurrent deformity and lengthen the shortened first metatarsal. Methods. 36 lengthening scarf osteotomies were undertaken in 31 patients. Clinical (AOFAS and SF12 scores) and radiographic measures (IMA, HVA) were taken pre- and post-operatively. The maximum theoretical lengthening was 10mm, to prevent first MTP joint stiffness post-operatively. The actual lengthening was determined and measured intra-operatively. Results. There were 28 female and three male patients, with mean age at presentation 53.4 years. The mean follow-up was 3.9 years. Four cases were lost to follow-up. The mean first metatarsal lengthening achieved was 4.9mm (range 1–8mm). All of the osteotomies united without complication. The mean IMA reduction was 4.0° (p<0.001) and HVA 13.0° (p<0.001). The mean AOFAS score increase was 33.8 (p<0.001). There was no correlation between change in IMA and AOFAS score (r=−0.13) or between improvement in HVA and AOFAS score (r=−0.02). There was a positive trend but no correlation (r=0.28) between amount of metatarsal lengthening and change in AOFAS score. The inter- and intra-observer correlation was excellent. The SF12 physical sub-domains improved more than the mental sub-domains. Conclusion. We describe the largest series of lengthening scarf osteotomies for recurrent hallux valgus and symptomatic iatrogenic first brachymetatarsia. The significant improvement in both clinical and radiographical measures suggests the procedure is successful, with a low complication rate. Lengthening did not reduce the MTPJ range of movement. We hypothesise that restoring both the length and alignment enables greater weight-bearing under the first metatarsal head, reducing biomechanical transfer metatarsalgia

This paper tests the null hypothesis that there is no difference in recurrence for mild and moderate hallux valgus treated with Scarf osteotomy in the presence of a disrupted Meary's line compared to an intact line. At a minimum of 3 months follow up we retrospectively analysed radiographs, theatre and clinic notes of 74 consecutive patients treated with Scarf osteotomy for mild and moderate hallux valgus at a single centre. The patients were divided into Group A (n=30) – patients who on pre-operative weight bearing radiographs had a disrupted Meary's line, and Group B (n=44) – those with a normal Meary's line on pre-operative weight bearing radiographs. Our results demonstrate a statistically significant higher recurrence in group A compared to Group B with an odds ratio of 5.2 p = 0.006 [95% CI 1.6–6]. The association between a disrupted Meary's line and increased risk of recurrence for Scarf osteotomy remains valid and strengthened to an odds ratio of 7.1 p = 0.015 [95% CI 1.46 −34.4] when adjusted for confounding variables of age, sex and pre-operative IMA. On this basis we reject the Null hypothesis. In group A two out of 30 patients required revision surgery whilst none of the 44 patients in group B needed revision. In Group A the degree of IMA correction achieved equalled 8.1 degrees with a pre and post IMA of 16.0 and 7.9 degrees respectively. For Group B the degree of correction was 8.0 degrees with a pre and post IMA of 14.3 and 6.3 degrees respectively. Eight complications were reported in Group A and 9 in Group B. Our results demonstrate a statistically significant increased risk of recurrence when scarf osteotomy is performed for mild and moderate hallux valgus in the presence of a disrupted Meary's line

Introduction. The aim of this study was to assess whether routine X-Rays at six weeks altered the subsequent management of patients who underwent a Scarf osteotomy. Materials and Methods. Between 1997 and 2010, 218 consecutive primary scarf osteotomies of the first metatarsal were performed by two foot and ankle surgeons in a single unit. 71 were combined with an Akin closing wedge osteotomy of the proximal phalanx of the great toe and soft tissue release. Additional osteotomies were performed on the lesser toes in 30 cases. Intraoperative X-Rays were taken. We retrospectively looked at clinic letters for all patients who attended six weeks post operatively and recorded the outcomes following X-Rays. Results. 209 patients were assessed six weeks post operatively with radiographs of the foot. 9 patients were lost to follow up. Four patients (1.9%) were identified as having complications at the osteotomy: recurrence of deformity seen in two patients, delayed union with failure of fixation, and painless hypertrophic nonunion. Discussion. Only a very small proportion of patients developed complications at the osteotomy site following a Scarf osteotomy for hallux valgus. Both cases of recurrence were diagnosed clinically. Failure of fixation was due to poor patient compliance. No revision procedures were planned for any patients. Conclusion. The senior author no longer requests postoperative X-Rays routinely. We believe that the majority of patients may be safely and successfully assessed clinically following Scarf osteotomy without the need for routine X-Rays

This study was designed to assess the utility of the scarf osteotomy in the management of symptomatic adolescent hallux valgus. Methods. This is a consecutive case series of 30 patients (40 feet) with a mean follow up of 38.2 months (range 6–60 months). The mean age at the time of surgery was 14.2 years (range 10–17 years). American Orthopaedic Foot and Ankle Society scores (AOFAS) were collected at final follow up, along with a rating of the overall satisfaction. Any complications were recorded. Pre and postsurgical radiographic angles were measured (HVA, IMA and DMAA) and analysed using the students ‘t’ test. A second surgeon additionally recorded the angles to measure the inter-rater reliability using the Pearson product moment correlation. Results. The mean AOFAS score at final follow up was 91.2 (range 54–100). 87% of patients were either satisfied or very satisfied with their final outcome. 1 patient has been listed for revision surgery after symptomatic recurrence at 3 years follow up. Pre-op HVA, IMA and DMAA were 35.1, 16.1 and 16.3 respectively. Post-op values were 16.3, 8.8 and 9.0 (p < 0.001 for each). Pearson's r coefficient values demonstrated good inter-rater reliability of measurement. Conclusion. We have presented the results of the largest case series of scarf osteotomies for adolescent hallux valgus reported in the literature at this point, as far as we are aware. AOFAS scores at final follow up are comparable to the smaller studies previously reported and provide evidence that good outcomes and high levels of patient satisfaction can be achieved. Early follow up demonstrates a low level of symptomatic recurrence, but longer term data is still required

Introduction. The Z or “scarf” osteotomy was first described by Meyer in 1926 and then by Burutaran in 1976. It was later popularised by Weil in the USA and Barouk in Europe in the 1990's and is now an accepted technique that forms part of a surgeons' armamentarium. The theory of Diffusion of Innovations was described by Rogers in 1962 to explain how novel ideas are accepted into practice across different industries, including medicine. It has never previously been used to study the adoption of ideas in foot and ankle surgery. Methods. This paper uses publication volume as a surrogate marker for adoption, as described previously by the authors. Briefly, a systematic review of the literature was carried out. MESH headings included ‘Hallux Valgus’, and ‘osteotomy’ or ‘SCARF’ or ‘Z osteotomy’ or ‘bunionectomy’. 2818 publications were identified and the abstracts were reviewed excluding 2699 publications for non-relevance. The data was analysed by year of publication, country of origin, as well as for level of evidence. Results. There were 120 publications relating to SCARF osteotomy, which when plotted on a graph produced an s shaped curve. 58% of publications came from Europe and 38% from the USA. There was only a single level 1 paper published in 2008. Discussion. This study confirms that publication volume is a surrogate marker for adoption and that SCARF osteotomy became adopted by the late 2000's as indicated by the plateau on an s-shaped curve. Post market surveillance has led to a further rise in recent publications indicating that certain issues still need resolving before the laggards adopt this technique. Despite SCARF having been around for more than 80 years, very little high level evidence has been published of its effectiveness. Recommendations are made as to how future innovations should be introduced in foot and ankle surgery


Numerous procedures have been reported for the hallux valgus correction of the great toe. Scarf osteotomy is a versatile osteotomy to correct varying degrees of mild to moderate hallux valgus deformity. It can also be used for lengthening of the 1st ray as a revision procedure to treat metatarsalgia in patients who had previous shortening osteotomy. We wish to report a patient who had lengthening SCARF osteotomy for the metatarsalgia following previous hallux valgus correction and developed arthritis of the 1st MTPJ in a short term which required fusion. A 49 year old female patient was seen with pain and tenderness over the heads of the 2nd and3rd metatarsal of the right foot. She had hallux valgus correction 10years ago with a shortening osteotomy of the 1st metatarsal. She developed metatarsalgia which failed to conservative management. She had a lengthening SCARF osteotomy for the metatarsalgia in 2004. She had good symptomatic relief for two years and then started having pain over the 1st MTPJ. On examination she had limited movements of the 1st MTPJ and tenderness over the dorsolateral aspects of the 1st MTPJ suggestive of arthritis. Radiographs of the foot showed healed osteotomy with no evidence of AVN of the 1st MT head but features suggestive of osteoarthritis. She had fusion of the 1st MTPJ performed in 2008 for the arthritis following which symptoms resolved. This case highlights that arthritis of the 1st MTPJ can occur in the absence of an AVN of the metatarsal head and patients need to be warned of this potential complaining when having the lengthening SCARF osteotomy for metatarsalgia following a previous shortening osteotomy of the 1st ray

Aims. The purpose of this study was to analyse the biomechanics of walking, through the ground reaction forces (GRF) measured, after first metatarsal osteotomy or metatarsophalangeal joint (MTP) arthrodesis. Patients and Methods. A total of 19 patients underwent a Scarf osteotomy (50.3 years, standard deviation (. sd. ) 12.3) and 18 underwent an arthrodesis (56.2 years,. sd. 6.5). Clinical and radiographical data as well as the American Orthopaedic Foot and Ankle Society (AOFAS) scores were determined. GRF were measured using an instrumented treadmill. A two-way model of analysis of variance (ANOVA) was used to determine the effects of surgery on biomechanical parameters of walking, particularly propulsion. Results. Epidemiological, radiographical and clinical data were comparable in the two groups and better restoration of propulsive function was found after osteotomy as shown by ANOVA (two way: surgery × foot) with a surgery effect on vertical forces (p < 0.01) and a foot effect on anteroposterior impulse (p = 0.01). Conclusion. Patients who underwent Scarf osteotomy had a gait pattern similar to that of their non-operated foot, whereas those who underwent arthrodesis of the first (metatarsophalangeal) MTP joint did not totally recover the propulsive forces of the forefoot. Take home message: The main findings of this study were that after surgical correction for hallux valgus, patients who underwent scarf osteotomy had a gait pattern similar to that of their non-operated foot in terms of forefoot propulsive forces (Fz3, Iy2), whereas those who underwent arthrodesis of the first MTP joint had not.

When performing scarf osteotomies some surgeons use intraoperative radiography and others do not. Our experience is that when using intraoperative radiography we often change the osteotomy position to improve the correction of the hallux valgus angle and sesamoid position. We report the results of a single surgeon series of 62 consecutive patients who underwent a scarf osteotomy for hallux valgus. The first 31 patients underwent surgery without the use of intraoperative radiographs and the subsequent 31 patients underwent surgery with the use of intraoperative radiographs, this reflects a change in the surgeons practice. Hallux valgus angle, intermetatarsal angle, distal metatarsal articular angle and sesamoid position using the Hardy Clapham grading system were recorded. All patients had measurements recorded from weight baring radiographs taken pre operatively as well as at 6 and 12 weeks post operatively. Intraoperative measurements were also recorded for all patients in the intraoperative radiography group. The mean hallux valgus angle preoperatively was 28.5° in the control group and 30.5° in the intraoperative radiography group. The mean hallux valgus angle in the control group at 6 weeks was 12.4° and at 12 weeks was 12.6°. The mean hallux valgus angle in the intraoperative radiography group at 6 weeks was 10.5° and at 12 weeks was 9.8°. The median sesamoid position pre operatively was 4 for both groups. At 6 and 12 weeks the sesamoid position improved by a median of 1 position in the control group and 2 positions in the intraoperative radiography group (p<0.05). We recommend that surgeons who do not routinely use intraoperative radiography undertake a trial of this. We have found that the use of intraoperative radiography improves the correction of hallux valgus angle and sesamoid position. These have been shown to increase patient satisfaction and reduce recurrence

Background:. The Chevron osteotomy is straightforward, requires less dissection and allows earlier rehabilitation than some other osteotomies. However it is generally perceived as unsuitable for severe deformities even though a 2012 meta-analysis and an earlier RCT failed to show any advantage of the scarf over the chevron. We aim to assess the correctability of severe HV comparing the correction, the clinical outcomes and complications of the Chevron osteotomy with other techniques employed in a consecutive series. Methodology:. We reviewed a series of 92 cases of severe hallux valgus (IMA >17° regardless of the HVA). The follow-up period varied from 1 to 4 years. Pre-operative x-rays and final post-operative weight-bearing x-rays were performed. Outcome scores (MOXFQ and AOFAS), IMA, HVA and foot width were collected. Complications were monitored. Results:. There were 97 cases of severe hallux valgus performed during the study period, 55 were treated with a large-shift modified Chevron osteotomy, 42 with a number of other techniques that included Ludloff, Basal or Scarf osteotomy and also fusion in the form of a Lapidus or 1. st. MTP. The average pre-operative measurements were IMA of 19.1°, HVA of 40°, osseous forefoot width of 93.2 mm and the forefoot: hindfoot ratio was 3.11. Post-operatively the measurements were IMA of 9.2 and HVA of 9.76, the osseous forefoot width was 82.8 mm and the forefoot: hindfoot ratio was 2.57. Radiological outcomes for the Chevrons were similar to the alternative techniques though the rate of recovery was better. There is an increase in the rate of screw removal after a large shift Chevron osteotomy, reasons for this are discussed. Conclusion:. The Chevron osteotomy is successful in the management of severe hallux valgus. It has the advantage of being a stable osteotomy that permits immediate weight-bearing and movement of the MTP joint

Failed Hallux Valgus Surgery Aim. We aim to explore the reasons behind long term failure of hallux valgus surgery. Patients & Methods. A series of patients with problems following failed hallux valgus surgery presenting to a tertiary referral unit is presented. There were 47 patients with 55 problematic feet, 45 were female. The mean age was 59 years (Range 25–79). The failed bunions were compared to a prospectively collected series of 80 patients with successful 1st metatarsal osteotomies, 40 ludloff and 40 scarf osteotomies. Before the index surgery, all the patients in the failed group, the predominant symptom was pain. Only 53% admitted deformity was an issue. A wide spectrum of procedures were performed, 13 Wilson's, 11 Keller's, 8 Chevron, 3 Bunionectomy, 2 Scarf, 1 Basal and 1 Mitchell's. In 16 patients the original procedure was unknown. The mean time to developing problems was 9.4 years (Range 0–45) with mean time to presentation 13.6 years. (Range 0–47) Radiographs revealed 2/3 of patients had relative shortening of the first metatarsal. Over 80% of x-rays demonstrated evidence of degenerative change. The mean AOFAS score deteriorated with increased shortening. The failed bunions had statistically significantly different AOFAS pain scores (15.1 vs 31.9 p < 0.05), function scores (25.02 vs 31.9 p < 0.05). Additionally, the hallux valgus angle was significantly higher (24 vs 11.7 p < 0.05) although there was no change in DMMA between the two groups (13 vs 7.6 p > 0.05). There was a significantly higher incidence of first ray shortening (12% vs 0% p < 0.05). Discussion. This represents an unusual series, with nothing similar in the literature. Problems following hallux valgus surgery do not present for over 10 years. Functional Scores deteriorate with increasing shortening. MTPJ degeneration is common and from our data we are unable to explain why

This study sought to determine the medium-term patient-reported and radiographic outcomes in patients undergoing surgery for hallux valgus. A total of 118 patients (162 feet) underwent surgery for hallux valgus between January 2008 and June 2009. The Manchester-Oxford Foot Questionnaire (MOXFQ), a validated tool for the assessment of outcome after surgery for hallux valgus, was used and patient satisfaction was sought. The medical records and radiographs were reviewed retrospectively. At a mean of 5.2 years (4.7 to 6.0) post-operatively, the median combined MOXFQ score was 7.8 (IQR:0 to 32.8). The median domain scores for pain, walking/standing, and social interaction were 10 (IQR: 0 to 45), 0 (IQR: 0 to 32.1) and 6.3 (IQR: 0 to 25) respectively. A total of 119 procedures (73.9%, in 90 patients) were reported as satisfactory but only 53 feet (32.7%, in 43 patients) were completely asymptomatic. The mean (SD) correction of hallux valgus, intermetatarsal, and distal metatarsal articular angles was 18.5° (8.8°), 5.7° (3.3°), and 16.6° (8.8°), respectively. Multivariable regression analysis identified that an American Association of Anesthesiologists grade of > 1 (Incident Rate Ratio (IRR) = 1.67, p-value = 0.011) and recurrent deformity (IRR = 1.77, p-value = 0.003) were associated with significantly worse MOXFQ scores. No correlation was found between the severity of deformity, the type, or degree of surgical correction and the outcome. When using a validated outcome score for the assessment of outcome after surgery for hallux valgus, the long-term results are worse than expected when compared with the short- and mid-term outcomes, with 25.9% of patients dissatisfied at a mean follow-up of 5.2 years.

Aims

The mainstay of surgical correction of hallux valgus is first metatarsal osteotomy, either proximally or distally. We present a technique of combining a distal chevron osteotomy with a proximal opening wedge osteotomy, for the correction of moderate to severe hallux valgus.

Patients and Methods

We reviewed 45 patients (49 feet) who had undergone double osteotomy. Outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) and the Short Form (SF) -36 Health Survey scores. Radiological measurements were undertaken to assess the correction.

The mean age of the patients was 60.8 years (44.2 to 75.3). The mean follow-up was 35.4 months (24 to 51).

Metatarsalgia is a recognised complication following iatrogenic shortening of the first metatarsal in the management of hallux valgus. The traditional surgical treatment is by shortening osteotomies of the lesser metatarsals.

We describe the results of lengthening of iatrogenic first brachymetatarsia in 16 females. A Scarf-type osteotomy was used in the first four cases and a step-cut of equal thicknesses along the axis of the first metatarsal was performed in the others.

The mean follow-up was 21 months (19 to 26). Relief of metatarsalgia was obtained in the six patients in whom 10 mm of lengthening had been achieved, compared to only 50% relief in those where less than 8 mm of lengthening had been gained.

One-stage step-cut lengthening osteotomy of the first metatarsal may be preferable to shortening osteotomies of the lesser metatarsals in the treatment of metatarsalgia following surgical shortening of the first metatarsal.

The purpose of this study was to compare the results of proximal and distal chevron osteotomy in patients with moderate hallux valgus.

We retrospectively reviewed 34 proximal chevron osteotomies without lateral release (PCO group) and 33 distal chevron osteotomies (DCO group) performed sequentially by a single surgeon. There were no differences between the groups with regard to age, length of follow-up, demographic or radiological parameters. The clinical results were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and the radiological results were compared between the groups.

At a mean follow-up of 14.6 months (14 to 32) there were no significant differences in the mean AOFAS scores between the DCO and PCO groups (93.9 (82 to 100) and 91.8 (77 to 100), respectively; p = 0.176). The mean hallux valgus angle, intermetatarsal angle and sesamoid position were the same in both groups. The metatarsal declination angle decreased significantly in the PCO group (p = 0.005) and the mean shortening of the first metatarsal was significantly greater in the DCO group (p < 0.001).

We conclude that the clinical and radiological outcome after a DCO is comparable with that after a PCO; longer follow-up would be needed to assess the risk of avascular necrosis.

We reviewed the outcome of distal chevron metatarsal osteotomy without tendon transfer in 19 consecutive patients (19 feet) with a hallux varus deformity following surgery for hallux valgus. All patients underwent distal chevron metatarsal osteotomy with medial displacement and a medial closing wedge osteotomy along with a medial capsular release.

The mean hallux valgus angle improved from −11.6° pre-operatively to 4.7° postoperatively, the mean first-second intermetatarsal angle improved from −0.3° to 3.3° and the distal metatarsal articular angle from 9.5° to 2.3° and the first metatarsophalangeal joints became congruent post-operatively in all 19 feet. The mean relative length ratio of the metatarsus decreased from 1.01 to 0.99 and the mean American Orthopaedic Foot and Ankle Society score improved from 77 to 95 points.

In two patients the hallux varus recurred. One was symptom-free but the other remained symptomatic after a repeat distal chevron osteotomy. There were no other complications.

We consider that distal chevron metatarsal osteotomy with a medial wedge osteotomy and medial capsular release is a useful procedure for the correction of hallux varus after surgery for hallux valgus.

While many forefoot procedures may be performed as a day case, there are no specific guidelines as to which procedures are suitable. This study assessed the early post-operative pain after forefoot surgery performed a day case, compared with conventional inpatient management.

A total of 317 consecutive operations performed by a single surgeon were included in the study. Those eligible according to the criteria of the French Society of Anaesthesia (SFAR) were managed as day cases (127; 40%), while the remainder were managed as inpatients.

The groups were comparable in terms of gender, body mass index and smoking status, although the mean age of the inpatients was higher (p < 0.001) and they had higher mean American Society of Anaesthesiologists scores (p = 0.002). The most severe daily pain was on the first post-operative day, but the levels of pain were similar in the two groups; (4.2/10, sd 2.5 for day cases, 4.4/10, sd 2.4 for inpatients; p = 0.53). Overall, 28 (9%) of patients who had their surgery as a day case and 34 (11%) of inpatients reported extreme pain (≥ 8/10). There were more day case patients rather than inpatients that declared their pain disappeared seven days after the surgery (p = 0.02). One day-case patient with excessive bleeding was admitted post-operatively.

Apart from the most complicated cases, forefoot surgery can safely be performed as a day case without an increased risk of pain, or complications compared with management as an inpatient.

Severe hallux valgus deformity is conventionally treated with proximal metatarsal osteotomy. Distal metatarsal osteotomy with an associated soft-tissue procedure can also be used in moderate to severe deformity. We compared the clinical and radiological outcomes of proximal and distal chevron osteotomy in severe hallux valgus deformity with a soft-tissue release in both. A total of 110 consecutive female patients (110 feet) were included in a prospective randomised controlled study. A total of 56 patients underwent a proximal procedure and 54 a distal operation. The mean follow-up was 39 months (24 to 54) in the proximal group and 38 months (24 to 52) in the distal group. At follow-up the hallux valgus angle, intermetatarsal angle, distal metatarsal articular angle, tibial sesamoid position, American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal score, patient satisfaction level, and complications were similar in each group. Both methods showed significant post-operative improvement and high levels of patient satisfaction. Our results suggest that the distal chevron osteotomy with an associated distal soft-tissue procedure provides a satisfactory method for correcting severe hallux valgus deformity.
