Highlights
•we compare the care burden and economic cost of two surgical approaches to hallux valgus correction.
•Care burden was assessed by the number of visits each patient required and the complications. The follow-up and costs of each were assessed and compared independently.
•Kramer osteotomy presented significantly higher care burdens, complication rates and associated costs during the first year of follow-up.

Introduction
Most studies of hallux valgus surgery focus on the radiological findings or on medium-term clinical follow-up. The results obtained using various osteotomy techniques do not differ greatly. However, patient comfort and the need for postoperative care do appear to present differences.

In the Kramer technique, the osteotomy is secured with a wire extruding from the skin of the foot. In this situation, patients may well experience problems (or at least discomfort) in the immediate postoperative period. Previous studies of the Kramer technique (also known as SERI, or percutaneous distal metatarsal osteotomy) do not report an increased number of complications. Early complications may not influence the outcome in the medium to long term, and patient discomfort during the postoperative period is rarely reflected in the analysis of one-year results obtained with standard scales such as AOFAS; in our experience, however, patient discomfort, the care burden (i.e., the number of visits and emergency service consultations) and the economic cost of immediate postoperative care are all aspects that should be borne in mind when assessing the merits of different surgical techniques.

In this study we compare the care burden and economic cost of two surgical approaches to hallux valgus correction–the Kramer and the scarf techniques–during the first postoperative year.

Methods
Retrospective review of two independent patient cohorts. Sixty-nine feet underwent Kramer osteotomy and 133 the scarf technique. Care burden was assessed by the number of visits each patient required and the complications. The follow-up and costs of each were assessed and compared independently.

Results
Both techniques obtain satisfactory clinical results at one year. However, comparison of clinical progression showed AOFAS score increases of 34.7 points for Kramer and 41.1 points for the scarf technique (p-value < 0.05). Patients in the Kramer group required a higher number of visits, especially postoperative emergency department visits (p < 0.05), and had a significantly higher number of complications (27.5% vs 6.7%, p < 0.05). The mean cost of follow-up was significantly higher in the Kramer group. (€ 218.97 vs. € 171.41, p < 0.05).

Conclusion
Kramer osteotomy presented significantly higher care burdens, complication rates and associated costs during the first year of follow-up. It is therefore a less cost-effective technique. Thus, even though according to the results of AOFAS we would not have changed our clinical practice, the analysis of these data has made us change our treatment strategy for hallux valgus and practically abandoned the use of the Kramer osteotomies.

An interesting way to look at the recovery journey for foot surgery. I must admit that my preferred technique of scarf OSTEOTOMY allows patients to be shod after two weeks. I cannot see the per cutaneous method described being in any way an advance in the field of foot surgery.
