Percutaneous Chevron/Akin (PECA) versus open scarf/Akin (SA) osteotomy treatment for hallux valgus: A systematic review and meta-analysis.

ABSTRACT:

Purpose

The objective of the study is to compare the radiographic and clinical results of two techniques for the treatment of hallux valgus that have the same indication, the open scarf/Akin (SA) technique and the percutaneous Chevron/Akin (PECA).

Methods

A meta-analysis was performed with the studies found during a systematic review of articles included in electronic databases until 30 May 2020. The pooled analysis was summarized according to clinical outcomes, such as visual analog pain scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) score, radiographic outcomes and complications, with a 95% confidence interval.

Results

Three studies comparing the open scarf/Akin (SA) versus the PECA techniques were added to the analysis, corresponding to 235 feet, 102 in the PECA group and 133 in the SA. The final mean difference in the hallux valgus angle was 0.80 degrees and in the intermetatarsal angle 0.53, in the last radiographic evaluation. In the AOFAS score, the final mean difference was 4.97 points and in the VAS 0.14 in relation to the last clinical evaluation. Exposure to radiation during the surgical procedure was higher in the PECA group with a mean of 35.53 seconds.

Conclusions

The PECA surgical technique for the treatment of hallux valgus when compared with SA demonstrated similar radiographic correction, pain and function after six months of follow-up but with a longer radiation exposure time.

Project description:BackgroundWhile proximal first metatarsal osteotomy combined with distal soft tissue realignment is accepted as standard treatment of moderate to severe hallux valgus with metatarsus primus varus, none of the described proximal metatarsal osteotomies address the hyper-obliquity of the first metatarsocuneiform joint. An opening-wedge osteotomy of the medial cuneiform can potentially correct the 1-2 intermetatarsal angle (IMA) in addition to normalizing the hyper-obliquity of the first tarsometatarsal (TMT) joint. The purpose of this study was to retrospectively review the early radiographic and clinical results of the use of a medial cuneiform opening-wedge osteotomy fixed with a low-profile wedge plate combined with distal soft tissue realignment for the treatment of hallux valgus.MethodsFourteen feet (13 patients; 2 male and 11 female, average age 56 years, range 22-75) with hallux valgus underwent an opening-wedge osteotomy of the medial cuneiform fixed with a low-profile nonlocking wedge plate combined with distal soft tissue realignment. The mean preoperative hallux valgus angle (HVA) was 32 degrees and the IMA was 16 degrees. HVA, 1-2 IMA, proximal first metatarsal inclination (PFMI), and presence of osteoarthritis of the first TMT joint were assessed on preoperative and final postoperative radiographs. Final postoperative radiographs were also evaluated for radiographic union and hardware failure at an average of 7 months (range, 3-19 months) postoperatively.ResultsA mean intraoperative correction of 19 degrees and 7 degrees was achieved for the HVA and IMA, respectively. The mean HVA was 22 degrees and the mean IMA was 11 degrees at the time of final follow-up. At final follow-up, a recurrence of the deformity was observed in 12/14 feet. There were 2 nonunions-one plate failure and one screw failure. No first TMT joint instability or arthritis was observed. All patients were ambulatory without assistive device in either fashionable or comfortable shoe wear.ConclusionMedial cuneiform opening-wedge osteotomy resulted in unreliable correction of HVA and IMA at short-term follow-up with a high rate of early recurrence of hallux valgus deformity and a complication rate similar to that of the Lapidus procedure. This procedure cannot be recommended for addressing hallux valgus in the setting of increased obliquity of the first TMT joint.Level of evidenceLevel IV, case series.

Project description:ObjectiveHallux valgus (HV) is a common foot deformity, and recurrence is one of the most serious complications after HV correction. As a result, the surgical technique with a lower recurrence rate is a dream. The purpose of the article should be to observe the correction effect of hallux valgus using a novel "V-cut" osteotomy on the first metatarsal head combined with fixation in mortise-shaped bone groove-plasty technique.MethodsTwenty-three consecutive patients (40 feet) with HV were included from March 2019 to May 2020, who were all treated using single screw fixation with V-cut osteotomy on the first metatarsal head combined with mortise-shaped metatarsal bone groove-plasty and Akin osteotomy on the first toe for hallux valgus correction. With a mean follow-up time of 21.7 months, the visual analogue scale (VAS) score and American Orthopedic Foot and Ankle Society (AOFAS) forefoot score and the changes of the hallux valgus angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA) were evaluated during the clinical follow-up. The paired t test was used for analytical statistics.ResultsThe VAS score improved from 6.78 ± 1.74 to 1.87 ± 1.45 and the AOFAS score improved from 53.9 ± 12.3 preoperatively to 94.7 ± 6.8 in the latest follow-up postoperatively (P < 0.01). Besides, the HVA improved from 30.0 ± 6.1° to 5.7 ± 2.8° (P < 0.01); the IMA changed from 13.1 ± 2.8° into 3.3 ± 1.6° (P < 0.01); and the DMAA ameliorated from 27.0 ± 8.4° to 5.9 ± 3.5° (P < 0.01). Only five toes had slight numbness and stiffness in early postoperative period, and these symptoms disappeared completely at 6 months after the surgery. Only one foot was corrected to excess. One screw stern protruding beneath the skin happened, which needed secondary screw removal under local anesthesia.ConclusionsSingle screw fixation with V-cut osteotomy on the first metatarsal head combined with fixation in mortise-shaped metatarsal bone groove-plasty and Akin osteotomy on the first toe is an effective way with low recurrence rate for HV correction.

Project description: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.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.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.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.ClinicalTrials.gov PRS Protocol Registration and Results System: NCT02886221.
