Chevron Osteotomy

A retrospective study of 15 Mitchell and 15 Chevron osteotomies was undertaken in order to compare the efficacy of these two procedures in the correction of hallux valgus. Patient satisfaction, clinical findings, and roentgenographic measurements were all carefully evaluated after follow-up periods of 21 ± 5 months for the Chevron and 34 ± 8 months for the Mitchell procedures. Differences observed were a better correction of the angle between the first and second metatarsals by the Mitchell osteotomy (2.3 vs 5.5 degrees) and a tendency to loose the correction in the immediate postoperative period for the Chevron osteotomy. However, no clinical superiority could be demonstrated, nor did patient satisfaction differ in the two techniques. The authors conclude that these procedures give essentially equivalent results. Although the outcome was generally considered satisfactory by the patient, nearly 40% of both groups had metatarsalgia in the lateral rays, which stresses the importance of carefully considering load distribution across the foot in planning any corrective surgery.>

Freiberg’S Disease

A retrospective study of the postsurgical results of 10 patients who had dorsiflexion osteotomy was undertaken. Patient satisfaction, clinical findings, and roentgenographic measurements were all carefully evaluated after an average duration of follow-up of 36.5 months. The procedure gave excellent results for all patients, with minimal loss of metatarsophalangeal motion and an average radiological metatarsal shortening of 2.3 mm and no postoperative metatarsalgia. The authors believe that the dorsiflexion osteotomy is a reasonable treatment for symptomatic Freiberg's disease. The procedure is reliable and not destructive, should further treatment be necessary.

BACKGROUND:Chevron osteotomy for the treatment of mild and moderate hallux valgus obtain good effects. The procedure is suitable for a variety of cases, thereby allowing for a significant degree of correction. This study aimed to investigate Chevron osteotomy procedures for the correction of hallux valgus in the medium-term (2010-2016) by podiatrists surgeons. It takes into account clinical and radiological findings as well as patient perspectives and level of satisfaction.METHODS: All patients were assessed preoperatively, postoperatively and at a final follow-up. Fifty feet (forty five patients). The mean age was 59.43 (range 32 to 80) years. All of the participants signed an informed consent form to take part in the study. The protocols include: chart review, clinical and radiological. Anterior-posterior weight-bearing radiographs were analyzed preoperatively and at final follow-up. All radiological data were assessed by two observers blinded. Clinical and functional measurements as well as evaluation of the satisfaction survey at the final visit were carried out by another researcher blinded to the study. All patients were analyzed with VAS and AOFAS score. It was applied to evaluate clinical effects.RESULTS:Inter and intra-observer reliability was evaluated (ICC- 95%). The average value of the hallux valge angle (HVA) decreased at final follow-up (25.30º {plus minus} 7.21 VS 17.98º{plus minus} 8.18; p=0.041). There was no significant reduction in the average value of the intermetatarsal angle (IMA) at final follow-up (13.13º {plus minus} 3.03 VS 11.3º {plus minus}3.18; p= 0.78). Final AOFAS scale was 83. This study show the relevance of magnet therapy, nail surgery and others additional procedures. No patient was dissatisfied with the aesthetic scarring.CONCLUSIONS: The results showed that radiological results at final follow-up weren´t compatible with relapse of the deformity. The definitive clinical results, and the degree of patient satisfaction achieved with this technique were favorable from the patients' point of view.

And Function

A retrospective study of the Chevron osteotomy procedure for hallux valgus was carried out on 112 patients (168 feet) with an average age of 39.7 years (range 19 to 61 years). The average follow-up was 4.4 years (range 13 months to 7.5 years). The preoperative diagnosis was symptomatic hallux valgus. The average preoperative intermetatarsal 1–2 angle was 15.5° (range 11° to 18°) and the hallux valgus angle was 28.1° (range 21° to 42°). The operation was effective in improving symptoms, cosmesis, and function and in decreasing the deformity.

Background: Recurrence is relatively common after surgical correction of hallux valgus. Multiple factors are discussed that could have an influence in the loss of correction. The aim of this study was to determine preoperative radiological factors with an influence on loss of correction after distal chevron osteotomy for hallux valgus. Methods: Five hundred twenty-four patients who underwent the correction of a hallux valgus by means of distal chevron osteotomy at our institution between 2002 and 2012 were included. We assessed weightbearing x-rays at 4 time points: preoperatively, postoperatively, and after 6 weeks and 3 months. We investigated the intermetatarsal angle (IMA), the hallux valgus angle (HVA), the distal metatarsal articular angle (DMAA), joint congruity, and the position of the sesamoids. Results: At all points of the survey, significant correction of the IMA and HVA was detected. The IMA improved from 12.9 (± 2.8) to 4.5 (± 2.4) degrees and the HVA from 27.5 (± 6.9) to 9.1 (± 5.3) degrees. Loss of correction was found in both HVA and IMA during follow-up with a mean of 4.5 and 1.9 degrees, respectively. Loss of correction showed a linear correlation with preoperative IMA and HVA, and a correlation between preoperative DMAA and sesamoid position. Conclusion: The chevron osteotomy showed significant correction for HVA, IMA, and DMAA. Preoperative deformity, in terms of IMA, HVA, DMAA, and sesamoid position, correlated with the loss of correction and could be assessed preoperatively for HVA and IMA. Loss of correction at 3 months persisted during the follow-up period. Level of Evidence: Level IV, retrospective case series.

Category: Bunion Introduction/Purpose: Hallux valgus is a common deformity of the forefoot. There are over 130 procedures described to correct hallux valgus. Classically, the treatment of mild to moderate hallux valgus is with a distal metatarsal osteotomy. A variety of fixation techniques have been described for use with this osteotomy most of which require partial or non-weight bearing until the osteotomy is healed. Tension Band fixation is a well-known principle in orthopedic surgery. The goal of the present study is to radiographically assess the maintenance of distal first metatarsal osteotomy fixation using a novel tension band device (Re+Line tension band bunion plate system, Nextremity Solutions) with immediate post-operative weight-bearing. Methods: The patient database for one surgeon was retrospectively reviewed for patients that underwent hallux valgus correction with the Re+Line tension band device between 2014 and 2017. Postoperative protocol included a soft dressing, firm surgical shoe, and weight-bearing as tolerated with a cane. Patients were excluded if fixation was achieved with something other than a tension band construct. Radiographs were obtained and reviewed retrospectively by 3 authors. Pre and postoperative hallux valgus (HVA) and intermetatarsal angles (IMA) were measured as described previously in the literature, and the changes in correction compared. Maintenance of correction and hardware integrity were assessed at final follow-up after weight bearing as tolerated in a surgical shoe in the postoperative period. Statistical analysis was performed using a Wilcoxon signed-rank test for the changes in HVA and IMA. Results: There was a total of 72 patients and 76 toes that underwent hallux valgus correction with a tension band construct, at a mean follow-up of 4.36 months. 68 of 72 patients were female. The average age was 60.8 years old. The mean preoperative HVA was 27.1 degrees. The mean postoperative HVA was 6.14 degrees, with a mean correction of 20.22 degrees (p<0.001). The mean preoperative IMA was 14.14 degrees. The mean postoperative IMA was 6.10 degrees, with a mean correction of 7.98 degrees (p<0.001). There was loss of reduction found in 6 of 76 toes (7.89%).There were zero cases of hardware failure. All osteotomies healed at final follow-up. Conclusion: This study shows successful radiographic outcome after hallux valgus correction using a tension band construct and allowing immediate full weight-bearing in a surgical shoe in the postoperative period. Significant deformity correction was achieved and maintained and all osteotomies healed. The Re+Line tension band bunion correction system can be safely used as a successful option to fix distal first metatarsal osteotomies, while allowing patients to fully weight bear in a surgical shoe postoperatively and potentially return to activities faster than when using traditional fixation methods. Future studies are needed to assess functional outcomes and patient satisfaction with this novel technique.

Category: Midfoot/Forefoot Introduction/Purpose: The purpose of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a Percutaneous Extra-articular Reverse-L Chevron (PERC) osteotomy. Methods: A total of 38 patients underwent 45 PERC procedures. A medial approach is used just proximal to the flare of the metatarsal head. The osteotomy is performed using a burr, the thickness of which is selected according to the planned correction and shortening. A second dorsolateral approach is then performed and the osteotomy is fixed using a self-drilling, self-tapping 3 mm diameter cannulated and headless compression screw. There were 35 women and three men. The mean age of the patients was 48 years (17 to 69). An additional percutaneous Akin osteotomy was performed in 37 feet and percutaneous lateral capsular release was performed in 22 feet. Clinical and radiological assessments included the type of forefoot, range of movement, the American Orthopedic Foot and Ankle (AOFAS) score, a subjective rating and radiological parameters. The mean follow-up was 59.1 months (45.9 to 75.2). No patients were lost to follow-up. Results: The mean AOFAS score increased from 62.5 (30 to 80) pre-operatively to 97.1 (75 to 100) post-operatively. A total of 37 patients (97%) were satisfied. At the last follow up there was a statistically significant decrease in the hallux valgus angle, the intermetatarsal angle and the proximal articular set angle. The range of movement of the first metatarsophalangeal joint improved significantly. There was more improvement in the range of movement in patients who had fixation of the osteotomy of the proximal phalanx. Conclusion: Preliminary results of this percutaneous approach are promising. This technique is reliable and reproducible. The PERC osteotomy procedure is an effective approach for surgical management of moderate hallux valgus which combines the benefits of percutaneous surgery with the versatility of the chevron osteotomy. Its main asset is that it maintains an excellent range of movement; other advantages relate to the procedure being performed on an outpatient basis and the absence of tourniquet use.

End Of Treatment

Results of biplanar chevron osteotomy performed on patients with mild-to-moderate hallux valgus deformity with an increased distal metatarsal articular angle (DMAA) are shown. The study included clinical data of 32 patients (54 feet) who had completed a 2-year follow-up, and radiological data of these 32 and other 29 patients (50 feet) for a total of 61 patients (104 feet, 53 right and 51 left). There were 59 females and two males with ages varying from 11 to 66 years. According to the AOFAS Hallux Rating, the preoperative average score (50) improved to 90 (average score after the surgery). The hallux valgus angle was improved from an average of 25° to 14°, the first intermetatarsal angle from 12° to 8° and the DMAA from 15° to 5°. At the end of treatment, 94% of patients were classified as having grade 0 or I sesamoid lateral sub-luxation. Given improvement in angles and 90% of patients satisfied with an average AOFAS postoperative score of 90, the technique seems indicated for treatment of symptomatic hallux valgus deformity with increased DMAA.

The chevron osteotomy for hallux valgus was modified by addition of screw fixation and change of the osteotomy angle. Thirty-six patients underwent this modified osteotomy. All had mild to moderate symptomatic hallux valgus deformities. No other forefoot procedures were performed. Standing radiographs were taken before surgery, at 1 month after surgery, and, for the 15 patients who returned for long-term follow-up, at 1 year or more after surgery. Overall, 35/42 procedures were rated as satisfactory without reservations and 7 were rated as satisfactory with mild reservations. All patients stated that they had some improvement in their preoperative symptoms, which included pain, cosmetic concerns, and shoe wear difficulties. Radiographically, none of the capital fragments displaced and there were no malunions, nonunions, nor evidence of avascular necrosis. The average metatarsophalangeal-1 angle improved 8° and the average intermetatarsal 1–2 angle improved 4°. This modification is relatively simple, increases stability, and allows early weightbearing. In our experience, the modified chevron osteotomy has been a very reliable procedure for mild to moderate symptomatic hallux valgus deformity.

To assess the survival rate of implants placed in the nasopalatine canal for the rehabilitation of patients with atrophic maxillae and the level of satisfaction of these patients. A retrospective study was performed between 2000 and 2009 of patients with severe atrophy of edentulous maxillae (Cawood and Howell's class V) rehabilitated with implant-supported prostheses with 1 implant placed in the nasopalatine canal. A preoperative computed tomography scan was obtained of all patients and all surgeries were performed by the same surgeon. The following parameters were assessed: neurosensory status of the anterior palate (using the pointed/blunt discrimination method); implant success rate according to criteria described by Albrektsson et al; patient satisfaction with the prosthetic treatment (using visual analogue scales). Thirteen patients with a mean age of 54.8 years were treated, 5 men and 8 women. Seventy-eight implants were placed: 13 in the nasopalatine canal, 6 in the zygomatic bone, 12 in the pterygomaxillary region, 2 in the frontomaxillary buttress and 45 in other locations. Six patients reported a slight decrease in sensitivity in the anterior palate after surgery, which disappeared in all cases within a few weeks. Two early failures (before prosthetic loading) and no late failures (after prosthetic loading) of nasopalatine implants were recorded, yielding a success rate for these implants of 84.6% after a mean follow-up of 70 months (range 24 to 132 months. High patient satisfaction with the prosthetic restoration was generally achieved in terms of comfort, stability, function, esthetics, and ease of cleaning. Residual bone is associated with the nasopalatine canal, even in patients with severe maxillary atrophy. This canal may be considered a possible location for an anterior implant when rehabilitating atrophic patients using implant-supported prostheses.
