Bilateral and concomitant pathology’ surgeries do not affect the outcomes of mini-open distal linear metatarsal osteotomy (Bosch osteotomy) with manipulation for hallux valgus deformity

BackgroundBosch osteotomy for hallux valgus (HV) deformity has advantages of reduction both the operating time and surgical dissection, and may be performed bilaterally and with fewer complications than other surgical procedures as well as early weight-bearing. However, there are few reports on the effects of bilateral simultaneous surgery, simultaneous surgery on concomitant pathologies, and the preoperative HV angle on the postoperative results. The present assessed the factors that might affect the improvement in clinical outcomes following mini-open Bosch osteotomy with manipulation to treat HV deformity.MethodsSeventy patients with 110 feet were included. They were divided into groups as follows: unilateral and bilateral simultaneous surgery groups, Bosch osteotomy alone and simultaneous surgeries for concomitant pathologies groups, and preoperative HV angle< 40° and ≥ 40° groups. Subjective clinical outcome scores using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and the HV and intermetatarsal first and second metatarsal (M1M2) angles according to the anteroposterior (A-P) view of the weighted foot X-ray were assessed preoperatively and at 12 months after surgery.ResultsThe mean HV angle, M1M2 angle and all subscales of the SAFE-Q score showed significant improvement at 12 months after surgery, regardless of simultaneous bilateral surgery, simultaneous surgery for concomitant pathologies, or the preoperative HV angle. On comparing the groups, there were no significant differences in the HV angle at 12 months after surgery. Significant inferiority at 12 months after surgery was found in the intermetatarsal angle in the simultaneous surgery for concomitant pathologies group and in all subscales of the SAFE-Q score in the HV angle ≥ 40° group.ConclusionMini-open Bosch osteotomy with manipulation for HV deformity demonstrated good results in both radiological assessments and subjective clinical scores at 12 months after surgery, even for simultaneous bilateral surgery, simultaneous concomitant pathologies’ surgery, and severe HV deformity.Level of EvidencePrognostic Level III, retrospective cohort study.     

Proximal oblique metatarsal osteotomy for hallux valgus using a plantar locking plate

Background

The purpose of this retrospective study was to evaluate the clinical and radiological results of hallux valgus surgery using a plantar locking plate.

Comparison of modified Mitchell and Chevron osteotomies for hallux valgus

BackgroundGood clinical and radiological outcomes in mild-moderate hallux valgus (HV) can be achieved with Chevron osteotomy (CO) and modified-Mitchell osteotomy (MMO). The main goal of the present study was to compare the clinical and radiological outcomes after CO and MMO in HV.MethodsThe study included 45 patients, comprising 40 females with a mean follow-up of 87.5 ± 27.8 months. The outcome measurements of metatarsal length (MT1), HV angle (HVA), intermetatarsal angle (IMA), clinical outcomes, and metatarsalgia were evaluated pre- and postoperatively.ResultsNo significant difference was determined between the MMO and CO groups in respect of metatarsalgia and AOFAS scores. The CO resulted in a significantly larger decrease in the MT1. The mean HVA and IMA correction was significantly greater after MMO than after CO.ConclusionSince MMO may prevent MT1 shortening, which is a typical problem in the Mitchell osteotomy, MMO may be preferred over CO in patients with preoperative shortened first metatarsal.     

The metatarsal double osteotomy in the correction of hallux valgus with mini-invasive techniques

The mini invasive corrective surgery of static disorders of the forefoot is an undisputable progress because of its decreased morbidity with a simplified functional postoperative follow-up. These indications have been limited for a long time to mild deformities due to the creation of simple basi-metatarsal osteotomies or sub capital osteotomies of the first metatarsal thus limiting a more generalised application of these techniques in the more compound feet conditions. The combination of these two osteotomies allows to envisage the reaxation of major deformity but they can also apply in cases of mild or moderate deformities with additional metatarsus varus and angular deviation of the de metatarsal head with a DMAA >6°. The application of this double osteotomy is however delicate if one complies with the very principle of the mini invasive surgery which aims at preserving the possibility to return to an immediate postoperative weight-bearing on the forefoot with a final simple setting of the corrections by a strapping bandage, thus excluding any osteosynthesis. The risk to have a “floating” bone segment is high between the two osteotomies, with a secondary fracture deformity and a loss of the correction. To avoid these hurdles, we complied with a precise surgical timing, and with some technical rules, which allowed us to achieve the final expected result.     

Use of a percutaneous osteotomy with plate fixation in hallux valgus correction

Background

With hundreds of operative methods described for correction of hallux valgus we can state that the ideal surgical treatment is still controversial. The Bösch technique has been used as a percutaneous way of correcting hallux valgus deformities with the use of a pin fixation. The aim of this study is to evaluate a new method of fixation by using a percutaneous locking plate.

The Scarf first metatarsal osteotomy in the correction of hallux valgus deformity

The correction of hallux valgus has been dramatically improved by the scarf 1^st metatarsal osteotomy, which brings great versatility for covering all the indications. Its strong fixation allows an early functional recovery; the long-term follow-up confirms the reliability of this procedure, which can be combined with other osteotomies and soft tissue procedures. However, the surgeon has to determine pre and intraoperatively the correction that has to be applied; this technique is not difficult but has to be performed accurately. This is the interest of this article, which emphasizes the technical features that have to be applied.     

Comparison between Pin Fixation and Combined Screw Fixation in Proximal Chevron Metatarsal Osteotomy for Hallux Valgus Deformity Correction

BackgroundProblems associated with hallux valgus deformity correction using Kirschner-wire (K-wire) fixation include pin pullout and loss of stability. These complications are pronounced in the osteopenic bone, and few reports have focused on pin versus screw fixation. We examined the use of additional screw fixation to avoid these problems. The aim of this study was to compare outcomes of K-wire fixation (KW) and a combined K-wire and screw fixation (KWS).MethodsTwo groups with hallux valgus deformity, who were treated with a proximal chevron metatarsal osteotomy (PCMO), were compared based on the fixation method used. The KW group included 117 feet of 98 patients, and the KWS group included 56 feet of 40 patients. Clinically, the preoperative and final follow-up visual analog scale (VAS) pain score, American Orthopedic Foot & Ankle Society (AOFAS) hallux score, and patient satisfaction score were evaluated. Radiographically, hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured.ResultsThe mean VAS score decreased from 6.3 preoperatively to 1.6 postoperatively in the KW group and from 5.7 preoperatively to 0.5 postoperatively in the KWS group (p < 0.001). The mean AOFAS scores of the KW and KWS groups improved from 59.4 and 58.2, respectively, to 88.9 and 95.3, respectively (p < 0.001). Eighty-five percent in the KW group and 93% in the KWS group were satisfied with surgery. Clinical differences were not significant. The mean HVAs decreased from 34.7° to 9.1° in the KW group and from 38.5° to 9.2° in the KWS group (p < 0.001). The mean IMA decreased from 14.5° (range, 11.8°–17.2°) to 6.4° (range, 2.7°–10.1°) in the KW group and from 18.0° (range, 14.8°–21.2°) to 5.3° (range, 2.5°–8.1°) in the KWS group (p < 0.001). When IMA values at the 3-month postoperative and the final follow-up were compared, the IMA was significantly increased only in the KW group (p < 0.001) and no difference was found in the KWS group (p = 0.280).ConclusionsWe found a statistically significant difference in the decrease in IMA between the 2 groups. We recommend the combined pin and screw fixation in PCMO to enhance fixation stability and prevent potential hallux valgus correction loss.
