Midterm Results Following Minimally Invasive Distal Chevron Osteotomy: Comparison With the Minimally Invasive Reverdin-Isham Osteotomy by Means of Meta-analysis.

ABSTRACT:

Background/aim

To date, multiple different surgical techniques have been established for hallux valgus surgery, with each technique having its unique advantages and limitations. The open distal chevron osteotomy is widely accepted, but increasing patient demands have led several minimally invasive (MIS) techniques to be described in recent years. The aim of this study was to compare outcomes after minimally invasive (MIS) distal chevron osteotomy and the minimally invasive Reverdin-Isham method.

Patients and methods

We assessed clinical and radiographic outcomes after MIS chevron osteotomy in 57 feet of 49 consecutive patients with a mean follow-up of 58.9 (range=39.0-85.4) months. Outcomes after MIS Reverdin-Isham osteotomy were analyzed by means of a systematic literature review with a minimum follow-up of 6 months.

Results

Radiographic outcomes were significantly better in the MIS chevron cohort for intermetatarsal angle (p<0.001), hallux valgus angle and distal metacarpal articular angle (p<0.05). Concerning clinical outcomes, both methods provided comparable improvement.

Conclusion

MIS distal chevron osteotomy in mild to moderate hallux valgus deformity correction results in superior radiographic outcomes compared to the MIS Reverdin-Isham osteotomy. Sufficient correction of IMA cannot be achieved with the MIS Reverdin-Isham osteotomy.

Project description:Hallux valgus deformity affects more than 35% of people aged ≥65 years. Surgical correction in this population can be more complicated because of poor bone quality, worse deformity, and postoperative recovery challenges. The purpose of this study was to compare the radiographic and clinical outcomes of patients aged ≥65 years who underwent either open Lapidus or minimally invasive chevron Akin osteotomy for bunion correction. A retrospective review identified 62 patients aged ≥65 years who were treated surgically for hallux valgus with at least 1-year postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) scores (physical function and pain interference). Preoperative and at least 6-month postoperative radiographs were measured for the hallux valgus angle and intermetatarsal angle. PROMIS scores were obtained preoperatively and at 1 and/or 2 years postoperatively. Differences in demographic, clinical, and radiographic outcomes were assessed using the Mann Whitney U test and P values were adjusted for a false discovery rate of 5%. There was no difference between the MIS and open cohorts in pre- or postoperative radiographic measurements or clinical outcomes at any time point. At 1 year postoperatively, both groups had statistically significant improvements in the PROMIS pain interference domain but only the MIS group had a statistically significant improvement in the PROMIS physical function domain. Clinical significance was equivocal. At 2 years postoperatively, there were clinically and statistically significant improvements in the PROMIS pain interference and physical function domains for the open and MIS groups. Patients in both surgical groups had improvement in radiographic measurements and 2-year PROMIS scores, although there was no clinical or statistical difference found between groups. MIS and open surgical techniques appear to be safe and effective in correcting hallux valgus in older patients; however, patients may need to be counseled that maximum improvement after surgery may take more than 1 year.

Project description:BackgroundFemale urethral stricture (FUS) represents a sporadic condition. There is a lack of data and standardized guidelines on diagnostics and therapeutics. Several surgical techniques have been described for FUS urethroplasty, among which the flap-based or graft-based ones are most reported. Buccal mucosa graft (BMG) represents the gold standard for male urethroplasty, and this can theoretically be applied also to FUS treatment.ObjectiveTo describe and present preliminary results of a novel minimally invasive technique for buccal mucosa dorsal graft (mini-dorsal BMG) urethroplasty for the treatment of FUS.Design setting and participantsThis is a retrospective study on buccal mucosa dorsal graft urethroplasty for the treatment of FUS.Surgical procedureEvery patient was placed in lithotomic position. Two stiches were placed at 10 and 2 o'clock positions to facilitate the dorsal median urethrotomy. The margins of the incised dorsal urethra at the 12 o'clock position are then dissected from the periurethral tissue. This dissection results in an elliptical raw area between the edges of the urethra over the periurethral tissue. The harvested BMG was fixed with several quilting sutures, using 5-0 and 4-0 absorbable sutures, to cover the raw area. The margins of the graft were sutured to the edges of the incised urethra.MeasurementsA chart review was performed.Results and limitationsThirteen patients underwent the mini-dorsal-BMG technique. The median preoperative uroflow was 5.6 (3-13) ml/s, and the median postoperative value was 23.4 (14-58) ml/s.ConclusionsThe mini-dorsal-BMG technique for the treatment of FUS gives good results with low complication rates. Other series and long-term follow-up are necessary to confirm the reproducibility of this technique.Patient summaryWe present the technical aspects and the promising preliminary results of a novel surgical technique for the treatment of female urethral stricture by using the buccal mucosa to correct this invalidating disease.
