Early results of distal metatarsal osteotomy through minimally invasive approach for mild-to-moderate hallux valgus

A prospective study was performed on 24 patients to evaluate the early results of our experience with minimally invasive distal metatarsal osteotomy to treat mild-to-moderate hallux valgus deformities in adults. After failure of conservative treatment and persistence of footwear-related pain, a percutaneous distal first metatarsal osteotomy was performed, stabilized by a Kirschner wire, followed by immediate weight bearing. At final follow-up, clinical assessment showed that 31 of 36 patients were satisfied with their results. At a mean of 21 months, weight-bearing foot radiographs showed significant change compared with the preoperative status : the average corrections of hallux valgus angle and first intermetatarsal angle achieved were 13.10 and 5.40, respectively (p < 0.001). No cases showed nonunion, malunion, overcorrection, transfer metatarsalgia or osteonecrosis. The technique appeared in this study to be an effective, safe and simple option for correction of a painful mild-to-moderate hallux valgus deformity.     

Treatment of hallux valgus with an increased distal metatarsal articular angle: evaluation of double and triple first ray osteotomies

During a 12-year period in which 878 hallux valgus corrections were performed, 18 patients (21 feet) with symptomatic hallux valgus deformity and an increased distal metatarsal articular angle (DMAA) underwent periarticular osteotomies (double or triple first ray osteotomies). They were studied retrospectively at an average follow-up of 33 months. The surgical technique comprised a closing wedge distal first metatarsal osteotomy combined with either a proximal first metatarsal osteotomy or an opening wedge cuneiform osteotomy (double osteotomy). When a phalangeal osteotomy was added, the procedure was termed a "triple osteotomy." The average age of the patients at the time of surgery was 26 years. At final follow-up, the average hallux valgus correction measured 23 degrees and the average 1-2 intermetatarsal angle correction was 9 degrees. The DMAA averaged 23 degrees preoperatively and was corrected to an average of 9 degrees postoperatively. One patient developed a postoperative hallux varus deformity, and one patient developed a malunion, both of which required a second surgery. A hallux valgus deformity with an increased DMAA can be successfully treated with multiple first ray osteotomies that maintain articular congruity of the first metatarsophalangeal joint.     

Shortening Proximal Chevron Metatarsal Osteotomy for Patients With a Hallux Valgus Deformity With Advanced Arthritis

To correct hallux valgus deformities in patients with advanced arthritis of the first metatarsophalangeal joint, we designed a new reverse chevron-type shortening osteotomy technique that could be used to correct valgus deformities at the proximal metatarsal level, as well as shorten and lower the metatarsal, in a 1-time procedure. Sixteen feet in 16 patients with a minimum of 18 months follow-up who underwent a shortening proximal chevron metatarsal osteotomy for a hallux valgus deformity with advanced arthritic change between January 2014 and March 2016 were reviewed in this study. Double chevron osteotomies with 20° of plantar-ward obliquity at the proximal metatarsal level were made at 5-mm intervals for simultaneous valgus correction and metatarsal shortening. An additional Weil osteotomy of the second metatarsal was performed in all feet. Patients’ mean age was 57.88 ± 6.55 years. The deformity was satisfactorily corrected by the operation. The first metatarsal was shortened by approximately 8.75 mm, and the relative length of the second metatarsal did not differ significantly postoperatively (p?=?.179). The relative second metatarsal height, as seen on forefoot axial radiographs, was maintained constantly, with no significant difference (p?=?.215). No painful plantar callosity or transfer metatarsalgia under the second metatarsal head was observed postoperatively. A shortening proximal chevron metatarsal osteotomy for hallux valgus deformities with advanced arthritic change showed a good result with respect to deformity correction and pain relief. Appropriate lowering and an additional Weil osteotomy effectively prevented postoperative pain and painful callosity under the second metatarsal head.     

Correction of metatarsus primus varus associated with hallux valgus deformity using the arthrex mini tightrope: a report of 44 cases

Metatarsus primus varus must be addressed during correction of moderate to severe hallux valgus deformity. As an alternative to proximal osteotomy or first tarsometatarsal fusion for hallux valgus correction, this study presents a series of patients treated using the Arthrex Mini TightRope. A total of 36 patients (44 operations) with hallux valgus and metatarsus primus varus underwent correction using the Arthrex Mini TightRope. Assessment included measurement of radiographic parameters, the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot outcomes score, and the SF-12. The average hallux valgus angle improved from 32.2° to 15.2° (P < .0001). The average first intermetatarsal angle improved from 14.6° to 8.2° (P < .0001). The average distal metatarsal articular angle improved from 17.0° to 9.6° (P < .0001). The average AOFAS midfoot outcomes scores improved from 45.44 to 84.72 (P < .0001). Postoperative SF-12 physical and mental scores averaged 52.99 and 56.63. Only one patient had recurrence of deformity. Correcting metatarsus primus varus in association with hallux valgus deformity using the Arthrex Mini TightRope should be considered a treatment option. This technique is less invasive and seems capable of maintaining correction while allowing for early weight bearing and avoiding the need for a proximal first metatarsal osteotomy or Lapidus procedure.

Basal medial opening wedge first metatarsal osteotomy stabilized with a low profile wedge plate

Twenty patients underwent 25 basal medial opening wedge osteotomies of the first metatarsal stabilized using a low-profile wedge plate in combination with a distal soft tissue release, distal metatarsal osteotomy and Akin osteotomy as required for correction of a hallux valgus deformity. The mean clinical and radiographic follow-up was 12.2 months. Pre- and post operative radiographs available in 15 cases showed that the median hallux valgus angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA) were corrected from 45.5 to 13.1, 17.7 to 9.2 and 243 to 10.0 degrees respectively (p < 0.001). Final radiographic assessment for the whole series showed a median final HVA and IMA of 14.1 and 9.1 respectively. Radiographic union was noted in all but one case which was asymptomatic. One wound infection was treated with oral antibiotics, one hallux varus deformity required soft tissue reconstruction and there was one recurrence. The outcome was reported as good or satisfactory by the patients for 20 of 25 feet. Three patients reported stiffness in the first MTP joint, which improved with joint injection and manipulation. Two plates were removed for prominence. The basal medial opening wedge osteotomy stabilized with a low profile wedge plate was an effective addition for correcting a moderate to severe hallux valgus deformity as part of a double or triple first ray osteotomy.     

Proximal crescentic metatarsal osteotomy: the effect of saw blade orientation on first ray elevation

BACKGROUND: Moderate and severe hallux valgus deformities generally require a proximal metatarsal osteotomy to correct a widened intermetatarsal angle. Although excellent results have been reported using the proximal crescentic osteotomy, concerns have been raised about the incidence of postoperative dorsal malunion, which may lead to transfer lesions. The objectives of this paper were to evaluate the influence of saw blade angulation on the final position of the first metatarsal and to test a new technique used to ensure proper orientation of the osteotomy. METHODS: For part I of the study, 26 Sawbones specimens with hallux valgus deformities were corrected using a proximal crescentic osteotomy with the saw blade position incrementally rotated in the coronal plane. The sagittal change in the final position of the metatarsal was quantified radiographically and correlated to the saw blade orientation. For part II of the study, a Kirschner wire was placed in a vertical position into the medial cuneiform to serve as a guide for the crescentic saw blade in 13 cadaver feet with hallux valgus. Metatarsus primus elevatus was measured after surgical correction. RESULTS: Part I of the study demonstrated a highly linear relationship (R2=0.95) between first metatarsal elevation and the orientation of the saw blade. Every 10-degree of saw blade angulation resulted in a 2-mm change in the sagittal position of the first metatarsal. In part II of the study, the average change in metatarsus primus elevation for the 13 specimens after surgical correction of the hallux valgus deformity was only 1.1 mm (range -3.9 to +4.9 mm). Eleven of the 13 specimens had less than 2.5 mm of elevatus. CONCLUSION: Dorsal malunion of the first metatarsal after proximal crescentic osteotomy is a recognized complication. The final position of the hallux metatarsal is influenced by the coronal plane orientation of the saw. A new technique is described to aid the surgeon in proper alignment of the saw and help prevent excessive first ray elevation.     

The Spike Osteotomy for Hallux Valgus: A Clinical and Radiological Evaluation

A distal metatarsal osteotomy with soft tissue correction is a frequently performed operation to correct mild to moderate hallux valgus deformity. This is a prospective study of 28 feet in 25 patients who underwent spike osteotomy of the first metatarsal with medial capsulorraphy for symptomatic hallux valgus. The osteotomy is a distal metatarsal osteotomy with a spike fashioned in the plantar and lateral quarter of the proximal fragment and impacted into the trough created in the center of the distal fragment, providing lateral and plantar shift of the distal fragment. The American Orthopaedic Foot and Ankle Society's rating scale was used for functional assessment, and a visual analog scale gauged pain. The average follow-up was 27 months. The rating scale score improved from a mean preoperative value of 39/100 to 84/100. Twenty-six feet had complete pain relief, whereas 2 feet had a lesser degree of persistent metatarsalgia. A review of preoperative and postoperative radiographs showed that the hallux valgus angle improved from a mean 36 degrees preoperatively to 18 degrees postoperatively. Likewise, the mean 1 to 2 intermetatarsal angle improved from 13 degrees to 7.3 degrees. There was no incidence of avascular necrosis. Fourteen patients (16 feet) rated the outcome as excellent, 10 (11 feet) as good, and 1 patient with asymptomatic mild hallux varus deformity rated the result as fair. These results demonstrate that the spike osteotomy is a suitable operation for treatment of mild to moderate hallux valgus.     

Hallux valgus and first ray mobility. A prospective study

BACKGROUND: There have been few prospective studies that have documented the outcome of surgical treatment of hallux valgus deformities. The purpose of this investigation was to evaluate the effect of operative treatment of hallux valgus with use of a proximal crescentic osteotomy and distal soft-tissue repair on the first metatarsophalangeal joint. METHODS: All adult patients in whom moderate or severe subluxated hallux valgus deformities had been treated with surgical repair between September 1999 and May 2002 were initially enrolled in the study. Those who had a hallux valgus deformity treated with a proximal crescentic osteotomy and distal soft-tissue reconstruction (and optional Akin phalangeal osteotomy) were then invited to return for a follow-up evaluation at a minimum of two years after surgery. Outcomes were assessed by a comparison of preoperative and postoperative pain and American Orthopaedic Foot and Ankle Society scores; objective measurements included ankle range of motion, Harris mat imprints, mobility of the first ray (assessed with use of a validated calibrated device), and radiographic angular measurements. RESULTS: Of the 108 patients (127 feet), five patients (five feet) were unavailable for follow-up, leaving 103 patients (122 feet) with a diagnosis of moderate or severe primary hallux valgus who returned for the final evaluation. The mean duration of follow-up after the surgical repair was twenty-seven months. The mean pain score improved from 6.5 points preoperatively to 1.1 points following surgery. The mean American Orthopaedic Foot and Ankle Society score improved from 57 points preoperatively to 91 points postoperatively. One hundred and fourteen feet (93%) were rated as having good or excellent results following surgery. Twenty-three feet demonstrated increased mobility of the first ray prior to surgery, and only two feet did so following the bunion surgery. The mean hallux valgus angle diminished from 30 degrees preoperatively to 10 degrees postoperatively, and the mean first-second intermetatarsal angle decreased from 14.5 degrees preoperatively to 5.4 degrees postoperatively. Plantar gapping at the first metatarsocuneiform joint was observed in the preoperative weight-bearing lateral radiographs of twenty-eight (23%) of 122 feet, and it had resolved in one-third (nine) of them after hallux valgus correction. Complications included recurrence in six feet. First ray mobility was not associated with plantar gapping. There was a correlation between preoperative mobility of the first ray and the preoperative hallux valgus (r = 0.178) and the first-second intermetatarsal angles (r = 0.181). No correlation was detected between restricted ankle dorsiflexion and the magnitude of the preoperative hallux valgus deformity, the post-operative hallux valgus deformity, or the magnitude of hallux valgus correction. CONCLUSIONS: A proximal crescentic osteotomy of the first metatarsal combined with distal soft-tissue realignment should be considered in the surgical management of moderate and severe subluxated hallux valgus deformities. First ray mobility was routinely reduced to a normal level without the need for an arthrodesis of the metatarsocuneiform joint. Plantar gapping is not a reliable radiographic indication of hypermobility of the first ray in the sagittal plane.     

Percutaneous distal metatarsal osteotomy for correction of hallux valgus

BACKGROUND: Distal osteotomy of the first metatarsal is indicated for the surgical treatment of mild-to-moderate hallux valgus deformity. The aim of this study was to evaluate the results of a subcapital distal osteotomy of the first metatarsal with use of a percutaneous technique. METHODS: From 1996 to 2001, 118 consecutive percutaneous distal osteotomies of the first metatarsal were performed for the treatment of painful mild-to-moderate hallux valgus in eighty-two patients. The patients were assessed with a clinical and radiographic protocol at a mean of 35.9 months postoperatively. The American Orthopaedic Foot and Ankle Society (AOFAS) hallux-metatarsophalangeal-interphalangeal scale was used for the clinical assessment. RESULTS: The patients were satisfied following 107 (91%) of the 118 procedures. The mean score on the AOFAS scale was 88.2 +/- 12.9 points. The postoperative radiographic assessments showed a significant change (p < 0.05), compared with the preoperative values, in the mean hallux valgus angle, first intermetatarsal angle, distal metatarsal articular angle, and sesamoid position. The valgus deformity recurred after three procedures (2.5%), the first metatarsophalangeal joint was stiff but not painful after eight (6.8%), and a deep infection developed after one (0.8%). The infection resolved with antibiotic therapy. CONCLUSIONS: The percutaneous technique proved to be reliable for the correct execution of a distal linear osteotomy of the first metatarsal for the correction of a painful mild-to-moderate hallux valgus deformity. The clinical results appear to be comparable with those obtainable with traditional open techniques, with the additional advantages of a minimally invasive procedure, a substantially shorter operating time, and a reduced risk of complications related to surgical exposure.
