Role of lateral soft tissues release in percutaneous hallux valgus correction: A medium term retrospective study. World J Orthop 2023; 14:843-852. [PMID: 38173806 PMCID: PMC10758593 DOI: 10.5312/wjo.v14.i12.843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 10/12/2023] [Accepted: 11/17/2023] [Indexed: 12/15/2023] Open
Abstract
BACKGROUND In the field of minimally invasive surgery (MIS) for the treatment of hallux valgus (HV), different techniques have begun to emerge in the literature concerning the distal osteotomy of the first metatarsal bone, the synthesis or not of the metatarsal head, the possible association with lateral soft tissues release (LSTR) and osteotomy of the base of the first phalanx. AIM To evaluate the role of LSTR on percutaneous HV correction, evaluating functional and radiographical results. METHODS From January 2012 to May 2016 a total of 396 patients with mild to moderate symptomatic HV treated with the MIS technique were included in this retrospective study. The technique provides no internal fixation (WOS). Patients were divided into the LSTR group and no LSTR group (LSTR N). This surgical procedure (LSTR) was reserved for insufficient HV angle (HVA) correction during fluoroscopic control. Patients were evaluated at each follow-up by two other authors after appropriate training by senior authors (first practitioners). Clinical evaluation was performed before surgery, 6 mo after surgery, and 48 mo follow-up. American Orthopaedic Foot and Ankle Society (AOFAS) and visual analog scale (VAS) score was used to evaluate pain and function, and complications were recorded. In addition, the incidence of relapses and the degree of joint range of motion (ROM) with the association with the LSTR (capsule, adductor tendon, phalanx-sesamoid ligament, and the deep transverse metatarsal ligament) were evaluated. Radiological parameters included HVA and intermetatarsal angle (IMA). Patient satisfaction was assessed. Student t-test and Fisher exact test were used to assess statistical analysis. RESULTS From our study it is clear that no differences in term of HVA, VAS, IMA correction, rate of complications, and AOFAS score were found between groups, while a significant improvement of the same variables was found in each group between pre and postoperative values. A significant improvement in ROM at 6 mo (P = 0.018) and 48 mo (P = 0.02) of follow-up was found in LSTR N group. Complications were rare in both groups. CONCLUSION LSTR procedure on percutaneous HV correction seems to increase postoperative joint stiffness with a comparable incidence of relapse and a low incidence of complications.

Abstract
Background Although percutaneous surgery for the treatment of hallux valgus is popular in Europe, there is sparse English written literature documenting its efficacy. This study described the operative techniques using percutaneous basal closing wedge osteotomy of the first metatarsal in correction of moderate to severe hallux valgus (HV) and its short-term clinical outcomes. We postulated that satisfactory correction of hallux valgus (HV) angle, intermetatarsal (IM) angle, and patients' clinical outcomes could be achieved with this technique. Methods We conducted a retrospective review of 25 feet in 23 patients who underwent a percutaneous basal closing wedge osteotomy of the first metatarsal (MT1) combined with a mini-open modified McBride procedure and mini-open resection of medial eminence. Follow-up averaged 21.5 months. Radiographic outcomes included pre- and postoperative HV angle, IM angle, absolute and relative shortening of MT1, and time to union. American Orthopaedic Foot & Ankle Society (AOFAS) scores were compared between pre- and postoperatively. Results The average HV angle improved from 39.4 (range, 29-58.3) degrees preoperatively to 14.7 (range, 0.1-23.2) degrees postoperatively (P < .05). IM angle improved from 14.9 (range, 6.7-22.4) degrees to 6.6 (range, 0.9-14.8) degrees (P < .05). The average absolute shortening was 3.8 (range, 0.27-12.91) mm and the relative shortening was 0.8 (range, 0.05-1.91) mm. There was no delayed union or malunion at the osteotomy site. The average AOFAS score improved from 39 (range, 12-50) to 81 (range, 70-93) (P < .05). Conclusions Satisfactory hallux valgus deformity correction and patients' outcomes were achieved with this technique. Our results are similar to results reported in other studies using open techniques. There was no malunion or delayed union of the osteotomy. Level of Evidence Level IV, case series study.

Abstract
The aim of this study was to propose a finite element method based numerical approach for evaluating various hallux valgus treatment strategies. We developed three-dimensional hallux valgus deformity models, with different metatarsal osteotomy methods and Kirschner wire fixation strategies, under two types of standing postures. Ten Kirschner wire fixations were analyzed and compared. The fixation stability, bone stress, implant stress, and contact pressure on the osteotomy surface were calculated as the biomechanical indexes. The results showed that the biomechanical indexes of the osteotomy and Kirschner wire fixations for hallux valgus deformity could be effectively analyzed and fairly evaluated. The distal metatarsal osteotomy method provided better biomechanical indexes compared to the proximal metatarsal osteotomy method. This study proposed a finite element method based numerical approach for evaluating various osteotomy and Kirschner wire fixations for hallux valgus deformity before surgery.

Abstract
BACKGROUND Postoperative shoes are commonly used after forefoot surgery. This study's aim was to demonstrate that reducing rigid-soled shoe time to 3 weeks neither compromises functional outcomes nor does it produce complications. METHODS Prospective cohort study: 6 weeks versus 3 weeks of rigid postoperative shoe (100 and 96 patients respectively), after forefoot surgery with stable osteotomies. Manchester-Oxford Foot Questionnaire (MOXFQ) and pain Visual Analog Scale (VAS) were studied preoperative and one year postoperative. Radiological angles were also assessed after removing the rigid shoe and at 6 months. RESULTS The MOXFQ index and pain VAS depicted similar results in each group (group A: 29.8 and 25.7; group B: 32.7 and 23.7) with no differences between them (p = .43 Vs. p = .58). Moreover, no differences were reported in their differential angles (HV differential-angle p = .44, IM differential-angle p = .18) or in their complication rate. CONCLUSION In forefoot surgery with stable osteotomies, shortening the postoperative shoe time to 3 weeks, neither impairs clinical results nor the initial correction angle.

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. Foot Ankle Surg 2022; 28:1021-1028. [PMID: 35190276 DOI: 10.1016/j.fas.2022.02.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 01/11/2022] [Accepted: 02/14/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Bosch 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. METHODS Seventy 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. RESULTS The 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. CONCLUSION Mini-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 EVIDENCE Prognostic Level III, retrospective cohort study.

Abstract
BACKGROUND Hallux valgus is a common foot condition with numerous surgical techniques described. Minimally invasive surgery is becoming more popular, with resultant development of suitable fixation devices. The aim of this systematic review was to evaluate the evidence on the use of intramedullary devices in hallux valgus first metatarsal corrective osteotomies, and describe clinical and radiological outcomes, with an overview of techniques and implants used. METHODS We searched PubMed, Medline, Embase and EMCare databases, conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Radiological outcomes including the hallux valgus angle (HVA) and intermetatarsal angle (IMA) were recorded, as well as clinical outcome scores and complications. Methodological quality of included studies was assessed using the MINORS score. RESULTS Ten studies were included, comprising 696 feet in 745 patients. Data pooling and metanalysis was not possible due to overall low quality of evidence. Four implants were reported (Endolog, ISO Plate, V-Tek Plate, Link Fixator) and used with distal first metatarsal osteotomies, with improvement in HVA, IMA, and clinical outcome scores comparable to other fixation techniques. There were no reported cases of non-union. Complication rates were variable (all cause range of 0-21%) across all studies, with an overall low rate. CONCLUSION Intramedullary devices are viable and safe to use for hallux valgus first metatarsal osteotomies, with comparable radiological and functional outcomes to other techniques. Current evidence base is of low methodological quality, therefore high quality studies are required to further evaluate these devices.

Abstract
Due to their osteoconductive properties, allogenic bone screws made of human cortical bone have advantages regarding rehabilitation compared to other materials such as stainless steel or titanium. Since conventional screw drives like hexagonal or hexalobular drives are difficult to manufacture in headless allogenic screws, an easy-to-manufacture screw drive is needed. In this paper, we present a simple drive for headless allogenic bone screws that allows the screw to be fully inserted. Since the screw drive is completely internal, no threads are removed. In order to prove the mechanical strength, we performed simulations of the new drive using the Finite-Element method (FEM), validated the simulations with a prototype screw, tested the novel screw drive experimentally and compared the simulations with conventional drives. The validation with the prototype showed that our simulations provided valid results. Furthermore, the simulations of the new screw drive showed good performance in terms of mechanical strength in allogenic screws compared to conventional screw drives. The presented screw drive is simple and easy to manufacture and is therefore suitable for headless allogenic bone screws where conventional drives are difficult to manufacture.

Abstract
Objective
To present the clinical and radiographic results of hallux valgus surgical correction using four percutaneous techniques, chosen according to a predefined radiographic classification.
Methods
We prospectively evaluated 112 feet in 72 patients with hallux valgus operated over the course of 1 year. Percutaneous distal soft tissue release (DSTR) and the Akin procedure (DSTR-Akin) were performed in mild cases. In mild to moderate hallux valgus with distal metatarsal joint angle > 10°, we added the Reverdin-Isham (RI) osteotomy. In moderate cases with joint incongruity, we performed the percutaneous chevron (PCH). Finally, a Ludloff-like percutaneous proximal osteotomy fixed (PPOF) with a screw was proposed in severe cases with an intermetatarsal angle (IMA) > 17°. According to these criteria, 26 DSTRs-Akin, 36 PCHs, 35 RIs, and 15 PPOFs were performed. The mean follow-up was of 17.2 months (range: 12 to 36 months). The mean age at operation was 58.8 years (range: 17 to 83 years), and 89% of the patients were female.
Results
The mean preoperative hallux valgus angle (HVA) and the IMA decreased from 21° to 10.2° and from 11.2° to 10.3° respectively in the DSTR-Akin. In the RI, the mean HVA decreased from 26.6° to 13.7°, and the IMA, from 11.2° to 10.3°; in the PCH, the mean HVA decreased from 31° to 14.5°, and the IMA decreased 14.9° to 10.7°; as for the PPOF, the mean HVA decreased from 39.2° to 17.7°, and the IMA, from 11.8° to 6.8°. The average ankle and hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) increased from 49.2 to 88.6. The rate of complications was of 11%.
Conclusion
Our treatment protocol does not differ much from the classic ones, with similar results as well. We have as advantages less aggression to soft tissues and better cosmetic results. Level of Evidence: level IV, prospective case series.

Abstract
BACKGROUND We reviewed the rates of and reasons for hallux valgus (HV) recurrence and the rates of avascular necrosis following Scarf osteotomy. METHODS We searched the Cochrane Library, PubMed, and Embase databases for studies reporting operative management of HV using Scarf osteotomy. The primary endpoints were reasons for and rates of HV recurrence. The secondary endpoint was the rate of avascular necrosis. RESULTS We included 15 studies with 946 operations for HV. Seven studies reported no recurrence, six reported recurrence rates of 3.6-11.3%, one reported a recurrence rate of 30%, and one reported a recurrence rate of 78%. Thirteen studies (678 feet) reported other complications from Scarf osteotomy without avascular necrosis. CONCLUSIONS Although HV recurrence is not uncommon following Scarf osteotomy, patient-related factors, surgical competence, and longer follow-up are more likely to be associated with recurrence. Avascular necrosis is an infrequent complication in HV patients treated using Scarf osteotomy.

Abstract
BACKGROUND This study was aimed at assessing clinical and radiographic outcomes of the Minimally Invasive Intramedullary Nail Device (MIIND) to correct moderate to severe hallux valgus (HV) and the long-term persistence of its effects. METHODS This case series study involved 100 patients, 84 women and 16 men (mean age, 59 years), who underwent the MIIND procedure with a mean follow-up of 97 months. Assessment was performed preoperatively, postoperatively, at 6 and 12 months, and at last follow-up. Clinical outcomes were evaluated with American Orthopaedic Foot & Ankle Society (AOFAS) scores, visual analog scale (VAS), and patient satisfaction. Intermetatarsal angle (IMA), metatarsophalangeal hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), and tibial sesamoid position were assessed. Statistical analysis was performed. RESULTS The mean AOFAS score improved from 57.9 to 90.5 points, VAS scale was 1.5 ± 2.0, and patients' satisfaction was 8.7 ± 1.4. The mean correction of the HVA and IMA showed a significant correction; however, the effect of time was not statistically significant on DMAA. Sex (P = .047), severity (P = .050), associated procedures (P = .000), and preoperative angle (P = .000) showed significant association with HVA correction and its persistence over time. Age was not statistically significant. Complications were 9 cases of superficial wound infection and 6 recurrences. CONCLUSIONS The MIIND technique proved a viable procedure to correct moderate to severe HV with a low rate of complications and recurrence, producing significant correction of most radiographic parameters assessed and their persistence, even at long term. LEVEL OF EVIDENCE Level IV, case series study.

Abstract
BACKGROUND Hallux Valgus Surgery success depends not only on the operative technique, but also on the care of the foot during the postoperative period. Orthopedic shoes have been developed to decrease the weight load on the first ray, an excess of which might lead to a loss of fixation or pseudoarthrosis. The goal of this study was to determine how the load distribution changed as the forced applied to the foot increased, with and without an orthopedic shoe. Also, we compared to different shoe models. METHODS Pressure sensors were placed under the first metatarsal head and the heel of twenty specimens of fresh cadaveric adult feet. Two orthopedic shoes were chosen, a double padded (MS) and a reverse camber shoe (RCS). 10 kg loads were progressively applied, up to 60 kg. We first compared three instances: no shoe, MS and RCS. A secondary analysis comparing barefoot versus shoes was performed. A mean comparison was performed (ANOVA/T-student). RESULTS The mean pressure of the heed and the first metatarsal showed that there were significant differences between groups (P < .005). The secondary analysis (no shoe vs orthopedic shoes) showed that the pressure without shoe was significantly higher than with any orthopedic shoe (P < .005). There were no statistically significant differences between models of shoes (P = .402). CONCLUSION After a surgical procedure for hallux valgus fixation, postoperative shoes should be indicated to decrease the pressure on the first metatarsal head and heel in order to avoid an overload of the postoperative area. LEVEL OF EVIDENCE Cadaveric study. Level V.

The aim of this study was to evaluate clinical and radiographic outcomes of this device. METHODS A retrospective study with a prospective data collection was conducted. Patients underwent to Endolog procedures from September 2009 to April 2017 were enrolled. Mild HV deformity (HVA ≤ 19° and IMA ≤ 13°) or associated procedure to Endolog technique were excluded. The radiological (HVA, IMA and PASA) and clinical (AOFAS score) pre and post-operative data were compared through Wilcoxon Signed-Rank test. RESULTS 194 feet (144 moderate and 50 severe HV) underwent HV correction respecting study's criteria. AOFAS scores significantly improved from 31.0 ± 12.7 points preoperatively to 88.5 ± 8.0 at 24 months. Even all radiographic measurements significantly improved during 2 years' follow-up. Only 6 patients experienced complications: 4 cases of HV recurrence and 2 cases of intolerance device-related pain. CONCLUSIONS Endolog technique proved to be a valid option in the moderate-to-severe hallux valgus treatment, comparable to other surgical techniques described in literature.

Abstract
Minimal incision surgical principals rely on the soft tissue envelope to maintain stability that is supplemented by a variety of clinically recommended fixation methods. The extended distal first metatarsal osteotomy has renewed interest because of the ability to laterally translate, angulate, and rotate the metatarsal head in proper alignment with the sesamoids to a neutral alignment. The soft tissue envelope of capsule, ligaments, and tendons will re-align once the bone deformity is corrected. The periosteum is maintained to provide a biologic scaffold for new bone formation and must be minimally disrupted during the intervention."

Abstract
INTRODUCTION The Chevron osteotomy is a reliable and popular osteotomy for treating hallux valgus worldwide. Many modifications have been described, but none of them address the rotational deformity of the first metatarsal. The objective of this study is to describe a variation of biplanar Chevron osteotomy which can address first metatarsal rotation when necessary. METHODS The indications for the Rotational Biplanar Chevron Osteotomy (RBCO) are mild to moderate hallux valgus deformity associated with hallux pronation related to internal rotation of the first metatarsal bone. We describe a technique that uses a medial based wedge parallel to the plantar limb of the osteotomy in order to make the distal fragment free to correct rotation. RESULTS The more recent concern about hallux valgus surgery is the very interesting concept that this deformity really occurs in three different planes, and we may have mistreated the rotation component with our current techniques. Many authors have revisited many common techniques in order to adapt them to correct metatarsal pronation. To our best knowledge, this is the first paper to describe a modification of the Chevron osteotomy to address the rotation of the first metatarsal. CONCLUSION We can conclude that the rotational biplanar Chevron osteotomy can be an useful tool in the treatment of mild hallux valgus associated with metatarsal pronation.

Abstract
Percutaneous and minimally invasive surgery is one of the greatest advances in the operating field of orthopedic since the late 1990s. The potential advantages include a shorter operative time, quicker recovery, and reduced hospital stay compared with traditional open surgery. However, scientific validation of the safety and efficacy of hallux valgus (HV) percutaneous surgery remains inconclusive. The objective of the present study was to systematically review the published data and clinical evidence for percutaneous HV surgery, evaluate the scientific method of the reports, and clarify the indications, safety, efficacy, and potential risks of these surgical techniques. Two reviewers independently identified the studies using a PubMed search, with the keywords "hallux valgus," "osteotomy," "minimally invasive," and "percutaneous." Quality assessment was performed using the Coleman methodology scale, and each study was assigned a level of evidence and grade of recommendation. Eighteen studies were included and reported a total of 1534 procedures for percutaneous HV surgery on 1397 patients. Of the 18 studies, 14 (77.8%) were level IV, 2 (11.1%) were level III, and 2 (11.1%) were level II. Overall, the average angle correction of the HV deformity improved postoperatively. Regarding the complications, although some investigators revealed no major complications, others described deformity recurrence in 7.8%, stiffness of the first metatarsophalangeal joint in 9.8%, malunion in 4% to 8.7%, and infection rates ranging from 1.9% to 14.3%. The main indication for percutaneous HV surgery is the correction of mild deformities. The complication rate was elevated even in experienced surgeons. In conclusion, future research in percutaneous techniques should include adequately sized randomized control trials, standardization of treatment protocols, and the use of validated tools for the measurement of clinical outcomes.

Abstract
Objective To explore the effectiveness and advantage of three-dimensional (3D) printed navigation templates assisted Ludloff osteotomy in treatment of moderate and severe hallux valgus. Methods Between April 2013 and February 2015, 28 patients (28 feet) with moderate and severe hallux valgus who underwent Ludloff osteotomy were randomly divided into 2 groups ( n=14). In group A, the patients were treated with Ludloff osteotomy assissted with a 3D printed navigation template. In group B, the patients were treated with traditional Ludloff osteotomy. There was no significant difference in gender, age, affected side, and clinical classification between 2 groups ( P>0.05). The operation time and intraoperative blood loss were recorded. The ankle function of the foot at preoperation, immediate after operation, and last follow-up were assessed by the American Orthopedic Foot and Ankle Society (AOFAS) score. Besides, the X-ray film were taken to assess the hallux valgus angle (HVA), intermetatarsal angle (IMA), and the first metatarsal length shortening. Results All patients were followed up 18-40 months (mean, 26.4 months). The operation time and intraoperative blood loss in group A were significantly less than those in group B ( P<0.05). The HVA, IMA, and AOFAS scores in groups A and B at immediate after operaton and last follow-up were sinificantly improved when compared with preoperative values ( P<0.05); but no significant difference was found between at immediate after operation and at last follow-up ( P>0.05). No significant difference was found in HVA and IMA between group A and group B at difference time points ( P>0.05). There were significant differences in AOFAS score and the first metatarsal length shortening at immediate after operation and at last follow-up between 2 groups ( P<0.05). Except 1 case of metastatic metatarsalgia in group B, there was no other operative complications in both groups. Conclusion 3D printed navigation template assisted Ludloff osteotomy can provide accurate preoperative planning and intraoperative osteotomy. It is an ideal method for moderate and severe hallux valgus.

Abstract
Many different surgeries have been proposed for hallux valgus treatment, osteotomies being the currently recommended ones. Because of high recurrence rates, distal, diaphyseal and proximal osteotomies have been used to improve alignment and sesamoid reduction. The center of rotation of angulation (CORA) concept applies to any deformity and helps to completely realign 2 bone segments. When used with proximal osteotomies, bone displacement and angulation is performed obtaining complete deformity correction. The proximal oblique sliding closing wedge (POSCOW) osteotomy follows the CORA concept and permits preoperative planning. Future directions must include the correction of the pronation deformity of the metatarsal.

Abstract
Background: Although percutaneous surgery for the treatment of hallux valgus is popular in Europe, there is sparse English written literature documenting its efficacy. This study described the operative techniques using percutaneous basal closing wedge osteotomy of the first metatarsal in correction of moderate to severe hallux valgus (HV) and its short-term clinical outcomes. We postulated that satisfactory correction of hallux valgus (HV) angle, intermetatarsal (IM) angle, and patients’ clinical outcomes could be achieved with this technique. Methods: We conducted a retrospective review of 25 feet in 23 patients who underwent a percutaneous basal closing wedge osteotomy of the first metatarsal (MT1) combined with a mini-open modified McBride procedure and mini-open resection of medial eminence. Follow-up averaged 21.5 months. Radiographic outcomes included pre- and postoperative HV angle, IM angle, absolute and relative shortening of MT1, and time to union. American Orthopaedic Foot & Ankle Society (AOFAS) scores were compared between pre- and postoperatively. Results: The average HV angle improved from 39.4 (range, 29-58.3) degrees preoperatively to 14.7 (range, 0.1-23.2) degrees postoperatively ( P < .05). IM angle improved from 14.9 (range, 6.7-22.4) degrees to 6.6 (range, 0.9-14.8) degrees ( P < .05). The average absolute shortening was 3.8 (range, 0.27-12.91) mm and the relative shortening was 0.8 (range, 0.05-1.91) mm. There was no delayed union or malunion at the osteotomy site. The average AOFAS score improved from 39 (range, 12-50) to 81 (range, 70-93) ( P < .05). Conclusions: Satisfactory hallux valgus deformity correction and patients’ outcomes were achieved with this technique. Our results are similar to results reported in other studies using open techniques. There was no malunion or delayed union of the osteotomy. Level of Evidence: Level IV, case series study.

Abstract
Background Fixation of proximal chevron metatarsal osteotomy has been accomplished using K-wires traditionally and with a locking plate recently. However, both methods have many disadvantages. Hence, we developed an intramedullary fixation technique using headless cannulated screws and conducted a biomechanical study to evaluate the superiority of the technique to K-wire and locking plate fixations. Methods Proximal chevron metatarsal osteotomy was performed on 30 synthetic metatarsal models using three fixation techniques. Specimens in group I were fixated with K-wires (1.6 mm × 2) and in group II with headless cannulated screws (3.0 mm × 2) distally through the intramedullary canal. Specimens in group III were fixated with a locking X-shaped plate (1.3-mm thick) and screws (2.5 mm × 4). Eight metatarsal specimens were selected from each group for walking fatigue test. Bending stiffness and dorsal angulation were measured by 1,000 repetitions of a cantilever bending protocol in a plantar to dorsal direction. The remaining two samples from each group were subjected to 5 mm per minute axial loading to assess the maximal loading tolerance. Results All samples in group I failed walking fatigue test while group II and group III tolerated the walking fatigue test. Group II showed greater resistance to bending force and smaller dorsal angulation than group III (p = 0.001). On the axial loading test, group I and group II demonstrated superior maximum tolerance to group III (54.8 N vs. 47.2 N vs. 28.3 N). Conclusions Authors have demonstrated proximal chevron metatarsal osteotomy with intramedullary screw fixation provides superior biomechanical stability to locking plate and K-wire fixations. The new technique using intramedullary screw fixation can offer robust fixation and may lead to better outcomes in surgical treatment of hallux valgus.

Abstract
BACKGROUND Percutaneous surgery to correct deformities of the forefoot presents the advantages of using a minimal incision, which involves less soft tissue damage and less risk of wound complications. For severe deformities, percutaneous techniques have not been proven as effective. We propose a technique for the treatment of severe hallux valgus. METHODS In a sample of 52 feet operated on 48 patients, we performed a double percutaneous osteotomy (closure proximal osteotomy and a distal Akin) or triple when a Reverdin-Isham osteotomy was added. We measured preoperatively the American Orthopaedic Foot & Ankle Society (AOFAS) score at the 1-year and 2-year follow-up, as well as the values of hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular ankle (DMAA), and shortening and elevation of the first metatarsal. The presence of metatarsalgia was recorded before and after the surgery. RESULTS HVA, IMA, and DMAA improved from 39.3 ± 7.1, 17.0 ± 2.0, and 16 ± 8.7 to 11.2 ± 6.2, 8.4 ± 3.4, and 8.3 ± 6.2, respectively. In 5 cases (10%), there was an elevation of the distal metatarsal bone, but only in 2 cases did a transfer metatarsalgia develop. There were no significant correlations between the amount of shortening and the presence of postoperative metatarsalgia. Scores on the AOFAS scale improved from 47.6 ± 5.6 to 89.7 ± 10.1 points. CONCLUSION The results are comparable to those reported with other more established techniques. Transfer metatarsalgia did not correlate with lifting or shortening of the metatarsal. We indicate the percutaneous technique for IMA above 15 degrees and increased DMAA or congruent joints. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND Minimally invasive surgery (MIS) represents one of the most innovative surgical treatments of hallux valgus (HV). However, long-term outcomes still remain a matter of discussion within the orthopaedic community. The purpose of this longitudinal prospective study was to evaluate radiographic and functional outcomes in patients with mild-to-severe HV who underwent Reverdin-Isham and Akin percutaneous osteotomy, following exostosectomy and lateral release. METHODS Eighty patients with mild-to-severe symptomatic HV were treated by MIS. Clinical evaluation was assessed preoperatively, as well as at 3 and 12 months after surgery and at final follow-up of 48 months, using the American Orthopaedic Foot and Ankle Society (AOFAS) hallux grading system. Patient satisfaction and complications were recorded. Computer-assisted measurement of antero-posterior radiographs was taken preoperatively, as well as at 3 and 12 months after surgery and at 48-month follow-up, analysing the intermetatarsal angle (IMA), the hallux valgus angle (HVA), the distal metatarsal articular angle (DMAA) and the tibial sesamoid position. Also, the bridging bone/callus formation was evaluated at the different radiographic follow-ups, while the articular surface congruency and the metatarsal index were calculated only preoperatively and at the last follow-up. Patient satisfaction was assessed using the visual analogue score (VAS). Statistical analysis was carried out using the paired t test. Statistical significance was set at p < 0.05. RESULTS The mean AOFAS score was 87.15 points at the final follow-up of 48 months, and the VAS score was 8.35/10. The post-operative radiographic assessments showed a statistically significant improvement compared with preoperative values. The mean corrections of each angular value at the last follow-up were as follows: IMA 3.90°, HVA 12.50°, DMAA 4.72° and a tibial sesamoid position of 1.10. The articular surface was congruent in 77 (96.25%) cases and incongruent only in 3 (3.75%). The complete healing of the osteotomies was achieved in all series at 3-month follow-up. However, the results obtained in the correction of the severe HV deformities were less encouraging. CONCLUSIONS Minimally invasive surgery with Reverdin-Isham and Akin percutaneous osteotomy, in combination with previous exostosectomy and subsequent lateral soft-tissue release, is a safe, effective and reliable procedure for correction of mild-to-moderate HV. However, it requires a long learning curve because of the inherent difficulty of the mixed different surgical procedures.

Abstract
BACKGROUND Different surgical techniques are available to correct each type of Hallux Valgus (HV) deformity, and all present similar good results. No information is available relative to the cost of each technique compared to their individual success. OBJECTIVE To determine the cost-effectiveness-ratio (CER) of five different techniques for HV. METHODS We included 245HV surgeries performed in 179 patients. The severity was defined according to radiological parameters. For mild to moderate HV we included the Chevron, Modified-Scarf and Ludloff techniques; for severe HV: either Poscow-osteotomy or Lapidus-arthrodesis fixed with plates or screws. Weighted costs were estimated. CER was expressed in $US dollars per AOFAS-point. RESULTS The lowest weighted cost was observed for the Chevron-group, and the highest weighted cost was observed in the Poscow-osteotomy and Lapidus-arthrodesis fixed with plate groups. The AOFAS-score improvement was higher in the Chevron and Modified-Scarf groups. The CER found for Chevron and Modified-Scarf techniques were significantly less than for Poscow and Lapidus-techniques. CONCLUSION Cost-Effectiveness-Ratio was lower, and therefore better, in the groups with mild to moderate deformities operated with Chevron or Modified-Scarf techniques. In severe HV, the three techniques investigated presented similar CER. CER analysis is an additional factor that can be included in the decision making analysis in hallux valgus surgery.

Abstract
More than 200 different surgical techniques exist for hallux valgus (HV). Some of them are designed for mild, moderate, or severe deformities depending on their correction power. Nevertheless, they all correct only the coronal and/or sagittal plane deformity. Just a handful of them correct the known axial malrotation that exists in most HV cases. This malrotation is one possible factor that could be the source of recurrence of an operated HV as it has been described. We describe a new technique which simultaneously corrects the metatarsal internal rotation and varus deformity by rotating the metatarsal through an oblique plane osteotomy. This is performed with no bone wedge resection. Also, there is a broader bone surface contact than on a transverse proximal osteotomy. This technique is easy to remember and relatively simple to perform in primary and revision cases. The authors results show that it is as safe and effective as other procedures, with some advantages to be discussed. Levels of Evidence: Diagnostic Level 5. See Instructions for Authors for a complete description of levels of evidence.

Abstract
The percutaneous osteotomy based on a Hohmanntype first metatarsal subcapital linear osteotomy was introduced into Mainland China in the late 1980s. No internal fixation is used for stabilization of the osteotomy, leading unfortunately to unpredictable results. Despite its high acceptance by patients and enthusiasm by surgeons at present, the clinical outcomes of percutaneous surgery have not been promising. The authors have no experience of performing this osteotomy and report only on their management of the complications of this technique and their recommended treatment algorithm.

Abstract
Hallux valgus is one of the most common foot deformities. Proximal opening wedge osteotomy is used for the treatment of moderate and severe hallux valgus with metatarsus primus varus. However, hypermobility of the first tarsometatarsal joint can compromise the results of the operation, and a paucity of midterm results are available regarding proximal open wedge osteotomy surgery. The aim of the present study was to assess the midterm results of proximal open wedge osteotomy in a consecutive series of patients with severe hallux valgus. Thirty-one consecutive adult patients (35 feet) with severe hallux valgus underwent proximal open wedge osteotomy. Twenty patients (35.5%) and 23 feet (34.3%) were available for the final follow-up examination. The mean follow-up duration was 5.8 (range 4.6 to 7.0) years. The radiologic measurements and American Orthopaedic Foot and Ankle Society hallux-metatarsophalangeal-interphalangeal scores were recorded pre- and postoperatively, and subjective questionnaires were completed and foot scan analyses performed at the end of the follow-up period. The mean hallux valgus angle decreased from 38° to 23°, and the mean intermetatarsal angle correction decreased from 17° to 10°. The mean improvement in the American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal score increased from 52 to 84. Two feet (5.7%) required repeat surgery because of recurrent hallux valgus. No nonunions were identified. Proximal open wedge osteotomy provided satisfactory midterm results in the treatment of severe hallux valgus, with a low complication rate. The potential instability of the first tarsometatarsal joint does not seem to jeopardize the midterm results of the operation.

Abstract
BACKGROUND Hallux valgus (HV) treatment is continuously evolving, and no definitive treatment can be recommended. Osteotomies are the main surgical choice for these deformities, but no clear role for soft tissue procedures is available. OBJECTIVE To perform a retrospective comparison of the radiographic and clinical outcomes of 2 groups of patients with severe HV operated with the same osteotomy technique but differing on the type of lateral release. METHODS Two groups of patients with symptomatic moderate to severe HV deformities were operated with the same proximal metatarsal osteotomy, which differed on the type of lateral release: group 1 had limited transarticular lateral capsule release (n = 62), and group 2 complete lateral release, including capsule, adductor tendon, and intermetatarsal (IM) ligament (n = 57). We recorded the American Orthopaedic Foot & Ankle Society (AOFAS) score, HV and IM angles, first metatarsal shortening, concomitant metatarsal shortening osteotomies (Weil), Akin osteotomies, and complications. RESULTS The postoperative AOFAS score in group 1 was similar to that of group 2. The HV and IM angles improved in both groups with no significant difference. The multivariate analysis showed no influence of any variable analyzed on HV or IM angle improvement. Regarding AOFAS score improvement, a limited lateral release was associated with a higher increase in AOFAS score (P = .019). CONCLUSION No studies are available to identify which soft tissue structures are involved in HV deformities nor which have to be released, if any. A limited transarticular release can provide similar clinical and radiologic outcomes when compared with a classic open lateral release. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Background Minimally invasive distal metatarsal osteotomy (MIDMO) is to be indicated for all patients with angles of IMA <20° and HV <40°, but many authors doubt whether this procedure is capable of correcting all types of hallux valgus deformities. The aims of this study were to perform a geometric analysis of MIDMO indications and to show which preoperative radiological parameters are necessary to achieve sufficient contact between bone fragments and sufficient correction with this operative technique. Methods A geometric mathematical model in AP and lateral radiographic plane was created based on preoperative measurements of the intermetatarsal angle (IMA), subcapital metatarsal width, medial bunion eminence, and metatarsal length. MIDMO was simulated with possible dorsal/plantar fragment displacement in order to assess postoperative contact between fragments (either 4–5 mm or half of the metatarsal width) and sufficient correction (postoperative IMA 8°). Results The metatarsal neck should be at least 8 mm wider from the bunion eminence to achieve the minimally required contact between fragments. For sufficient correction, the metatarsal head translation should be at least 0.018 of the metatarsal length for every degree of IMA reduction. The medial bunion eminence, in comparison with metatarsal width/length size, determines whether MIDMO is a suitable procedure for a given patient. Conclusions MIDMO cannot sufficiently correct all deformations within the boundaries of IMA angle <20° and HV angle <40°. In patients with large eminences and narrow metatarsals, complications related to insufficient postoperative fragment contact can be expected, while sufficient hallux valgus correction in patients with small eminences and long metatarsals is questionable.

Abstract
Background Hallux valgus (HV) is a complex deformity of the forefoot altering the kinematics of walking. Many different treatment alternatives exist for the correction of hallux valgus, but to date, none has been shown to be more effective than any other. The rate of complications following hallux valgus surgery is variable and has been reported as ranging from 1 to 55 % in the scientific literature. The purpose of this preliminary prospective study was to evaluate the result of the Endolog device, an innovative titanium endomedullary nail, for the treatment of HV. Methods Thirty patients with mild-to-severe HV were treated with the Endolog device. Clinical evaluation was assessed preoperatively, as well as at 3, 6, 12, 24, and 48 months after surgery with a final follow-up at 4 years, using the American Orthopaedic Foot and Ankle Society (AOFAS) hallux grading system. Computer-assisted measurement of weight-bearing antero-posterior radiographs was taken preoperatively and postoperatively, as well as at 3, 6, 12, 24, and 48 months after surgery. Non-weight-bearing radiographs were taken before the patients were discharged. The radiological parameters measured included the intermetatarsal angle (IMA), the hallux valgus angle (HVA), the distal metatarsal articular angle (DMAA), and the tibial sesamoid position. Statistical analysis was carried out using the paired t test (p < 0.05). Results The mean AOFAS score was 93.98 points at the 48-month follow-up. The postoperative radiographic assessments showed a statistically significant improvement compared with preoperative values. The mean corrections for each angular value at the last follow-up were as follows: IMA 5.95°; HVA 16.81°; DMAA 10.70°; and tibial sesamoid 1.36°. Conclusion The Endolog is a safe and effective technique for the correction of HV deformity, to relieve pain and to preserve joint movement.

Abstract
We present a discussion on the use of proximal first-ray osteotomies in the surgical treatment for hallux valgus as a valid option compared with first-tarsometatarsal arthrodesis. Recent and historical literature tells us that stability of the first ray is a function of the alignment and reestablishment of retrograde stabilizing forces at the first tarsometatarsal joint. This realignment and stabilization may be accomplished with the use of distal soft tissue and proximal osteotomy procedures.

Abstract
BACKGROUND For hallux valgus correction, distal first metatarsal osteotomy is generally used for minor to moderate deformities, diaphyseal osteotomy for moderate deformities and basal osteotomy or arthrodesis for severe deformities. With the advent of locking plates, there has been renewed interest in opening wedge basal osteotomy. OBJECTIVE We undertook this study in order to understand the power and limitations of this osteotomy. METHOD Proximal opening wedge osteotomies were performed on saw bone models in four orientations, with three different wedge sizes: (1) perpendicular to the ground (PG); (2) perpendicular to the shaft (PS); (3) perpendicular to shaft with 30° declination (DEC); (4) 30° oblique (OB). Pre- and post-osteotomy measurements were made of axial and plantar translation and inter-metatarsal angle. RESULTS Plantar translation and intermetatarsal angle correction increased with increasing wedge size. The DEC osteotomy produced the greatest increase in length of metatarsal shaft, while the PS osteotomy gave the least. The most plantar translation was achieved with the DEC osteotomy. Overall, the PS osteotomy gave the largest correction of the intermetatarsal angle. CONCLUSION Although there are several published clinical case series of the proximal opening wedge osteotomy, this is the first study to fully evaluate its geometry.

Abstract
Moderate to severe hallux valgus is conventionally treated by proximal metatarsal osteotomy. Several recent studies have shown that the indications for distal metatarsal osteotomy with a distal soft-tissue procedure could be extended to include moderate to severe hallux valgus. The purpose of this prospective randomised controlled trial was to compare the outcome of proximal and distal Chevron osteotomy in patients undergoing simultaneous bilateral correction of moderate to severe hallux valgus. The original study cohort consisted of 50 female patients (100 feet). Of these, four (8 feet) were excluded for lack of adequate follow-up, leaving 46 female patients (92 feet) in the study. The mean age of the patients was 53.8 years (30.1 to 62.1) and the mean duration of follow-up 40.2 months (24.1 to 80.5). After randomisation, patients underwent a proximal Chevron osteotomy on one foot and a distal Chevron osteotomy on the other. At follow-up, the American Orthopedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal interphalangeal (MTP-IP) score, patient satisfaction, post-operative complications, hallux valgus angle, first-second intermetatarsal angle, and tibial sesamoid position were similar in each group. Both procedures gave similar good clinical and radiological outcomes. This study suggests that distal Chevron osteotomy with a distal soft-tissue procedure is as effective and reliable a means of correcting moderate to severe hallux valgus as proximal Chevron osteotomy with a distal soft-tissue procedure.

Abstract
More than 200 surgeries have been described for hallux valgus correction. The distal V-shape chevron-type osteotomy was described with no more than 50% translation of the distal fragment in relation to the metatarsal shaft. This concept of high, powerful correction for distal chevron osteotomy fixed by the Mini MaxLock Extreme ISO gives the surgeon the possibility of a mini-invasive rapid solution. A new technique of fixation is based on the Murawski and Beskin concept, because a powerful correction can be performed with a minimally invasive approach, but, in contrast to other studies, with stable osteotomy fixation.

Abstract
PURPOSE The proximal chevron osteotomy provides high correctional power. However, relatively high rates of dorsiflexion malunion of up to 17 % are reported for this procedure. This leads to insufficient weight bearing of the first ray and therefore to metatarsalgia. Recent biomechanical and clinical studies pointed out the importance of rigid fixation of proximal metatarsal osteotomies. Therefore, the aim of the present study was to compare biomechanical properties of fixation of proximal chevron osteotomies with variable locking plate and cancellous screw respectively. METHODS Ten matched pairs of human fresh frozen cadaveric first metatarsals underwent proximal chevron osteotomy with either variable locking plate or cancellous screw fixation after obtaining bone mineral density. Biomechanical testing included repetitive plantar to dorsal loading from 0 to 31 N with the 858 Mini Bionix(®) (MTS(®) Systems Corporation, Eden Prairie, MN, USA). Dorsal angulation of the distal fragment was recorded. RESULTS The variable locking plate construct reveals statistically superior results in terms of bending stiffness and dorsal angulation compared to the cancellous screw construct. There was a statistically significant correlation between bone mineral density and maximum tolerated load until construct failure occurred for the screw construct (r = 0.640, p = 0.406). CONCLUSION The results of the present study indicate that variable locking plate fixation shows superior biomechanical results to cancellous screw fixation for proximal chevron osteotomy. Additionally, screw construct failure was related to levels of low bone mineral density. Based on the results of the present study we recommend variable locking plate fixation for proximal chevron osteotomy, especially in osteoporotic bone.

Abstract
PURPOSE Proximal first metatarsal osteotomies are recommended for the surgical treatment of moderate to severe hallux valgus deformity. This study aimed to compare correction of intermetatarsal and hallux valgus angles and complications of proximal crescentic, Ludloff, proximal opening wedge, proximal closing wedge, proximal chevron and other proximal first metatarsal osteotomies. METHODS A systematic search for the keywords "(bunion OR hallux) AND (proximal OR crescentic OR basilar OR opening OR closing OR shelf OR Ludloff) AND osteotomy" in the online databases MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews was performed. RESULTS There was a mean correction of hallux valgus angle of 20.1° [confidence interval (CI) 18.7-21.4] and of intermetatarsal angle of 8.1° (CI 7.7-8.9). The overall complication rate reached 18.7 %. CONCLUSIONS The results of this study reveal higher corrective power of proximal osteotomies compared to meta-analysis data on diaphyseal osteotomies.

Abstract
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.

Abstract
Efforts are currently being made to improve results in hallux valgus treatment. Different studies to design procedures that are more stable and efficient to correct deformities are underway, and new techniques will be presented in the following years. Better fixation devices will offer reliability in corrections, and hopefully will allow faster rehabilitation with fewer restrictions. Understanding the concept of correction power is important when deciding which technique to use. The origin of hallux valgus is not known, but evidence exists to assume that a correct skeletal and soft tissue balance is important to prevent recurrence and obtain good function. We think that a correct metatarsophalangeal reduction, in which the final position of the hallux is defined mainly by the skeletal alignment and not soft tissues, will dictate the final result. Pushing the metatarsal bone over the sesamoids and not moving the sesamoids under the metatarsal head is a new concept and it may allow better results for our patients. It is hoped that understanding of biomechanics will continue to evolve, and radiological measurements and corrections will produce better functional results for patients.

Abstract
BACKGROUND Modern concepts in the postoperative treatment of first metatarsal osteotomies include special shoes that should decrease stress in the forefoot region. The purpose of this study was to determine plantar pressure distribution, wearing characteristics and stress-reducing effectiveness of five different types of commonly used postoperative shoes. Additionally, we wanted to modify the shoe that revealed the most favourable results in a way that improves forefoot relief as well as provides comfort to the patients. METHODS Eight persons consented to participate in the study. Plantar pressure distribution in five different types of postoperative shoes (Rathgeber(®) normal, Rathgeber(®) modified, 4. Darco(®) flat, Darco(®) VFE, Wocker(®)) was assessed using Mediologic(®) insoles. Also, subjective criteria considering wearing comfort, stability and rolling characteristics were evaluated. Based on the postoperative shoe revealing the most favourable results, further prototypes were developed. Each new model was targeted to meet the given requirements, minimal forefoot pressure, in a different way. RESULTS The Rathgeber(®) modified model revealed the most favourable results concerning plantar pressure distribution as well as subjective wearing characteristics. Therefore, it was chosen for further modifications. After adding an extra layer of high elastic and springy material for shock absorption at the hallux region, forefoot relief and wearing characteristics showed improved results. CONCLUSION The results of the present study indicate that damping material in the hallux region of postoperative shoes minimises stress in this region and improves patient's comfort.

BACKGROUND Recent pedobarographic studies have demonstrated decreased loading of the great toe region and the first metatarsal head at a short- and intermediate-term followup. The purpose of the present study was to determine if a postoperative rehabilitation program helped to improve weightbearing of the first ray after chevron osteotomy for correction of hallux valgus deformity. MATERIALS AND METHODS Twenty-nine patients with a mean age of 58 years with mild to moderate hallux valgus deformity who underwent a chevron osteotomy were included. Postoperatively, the patients received a multimodal rehabilitation program including mobilization, manual therapy, strengthening exercises and gait training. Preoperative and one year postoperative plantar pressure distribution parameters including maximum force, contact area and force-time integral were evaluated. Additionally the AOFAS score, ROM of the first MTP joint and plain radiographs were assessed. The results were compared using Student's t-test and level of significance was set at p < 0.05. RESULTS In the great toe, the mean maximum force increased from 72.2 N preoperatively to 106.8 N 1 year after surgery. The mean contact area increased from 7.6 cm(2) preoperatively to 8.9 cm(2) 1 year after surgery and the mean force-time integral increased from 20.8 N(*)sec to 30.5 N(*)sec. All changes were statistically significant (p < 0.05). For the first metatarsal head region, the mean maximum force increased from 122.5 N preoperatively to 144.7 N one year after surgery and the mean force-time integral increased from 42.3 N(*)sec preoperatively to 52.6 N(*)sec 1 year postoperatively (p = 0.068 and p = 0.055, respectively). The mean AOFAS score increased from 61 points preoperatively to 94 points at final followup (p < 0.001). The average hallux valgus angle decreased from 31 degrees to 9 degrees and the average first intermetatarsal angle decreased from 14 degrees to 6 degrees (p < 0.001 for both). CONCLUSION Our results suggest that postoperative physical therapy and gait training with a Chevron osteotomy may help to improve weightbearing of the great toe and first ray. Therefore, we believe there is a restoration of more physiological gait patterns in patients who receive this postoperative regimen.

Abstract
Many options exist for surgical correction of hallux valgus and associated metatarsus primus varus deformities. First-ray realignment and stabilization are keys to successful deformity correction. This article presents a brief review of first-metatarsal osteotomies in the correction of hallux valgus or metatarsus primus varus and summarizes arguments for proximal osteotomy with soft tissue balancing.

Abstract
Malunion of a first metatarsal osteotomy or fracture can result in dorsal angulation of the distal fragment and shortening of the metatarsal, among other deformities. Dorsal malunion can be caused by improper orientation of the osteotomy, poor intraoperative fixation, or loss of fixation post-operatively due to premature weight bearing or catastrophic failure. There is little in the literature on the rate and incidence of malunion following first metatarsal fractures treated either operatively or nonoperatively. However, treatment options would be similar as for malunion following an osteotomy. The treatment of malunions depends on how symptomatic the patient is, including pain, difficulty with ambulation, and whether they complain of transfer metatarsalgia.
