Purpose Several bony and soft tissue procedures have been described for the treatment of hallux valgus, and currently mini-invasive surgical techniques are preferred in order to reduce surgical trauma, complications, time of surgery and to allow an earlier recovery. The aim of this study is to analyse a series of 1,000 consecutive cases of hallux valgus, surgically treated by the minimally invasive SERI technique, reporting results at mid-term follow-up. Methods We prospectively studied 641 patients (1,000 feet) with symptomatic hallux valgus surgically treated by SERI osteotomy. Inclusion criteria were: age between 20 and 65 years, reducible mild or moderate hallux valgus, HVA≤40°, IMA≤20°, and arthritis of the first metatarsophalangeal joint up to grade 2 according to the Regnauld classification. Results The American Orthopaedic Foot and Ankle Society (AOFAS) score rose from 46.8±16.7 preoperatively to 89±10.3 at last follow-up. Radiographic control at follow-up showed a complete healing of the osteotomy and remodelling of the metatarsal bone. Low rate of complication has been reported.Conclusions This study demonstrated that the SERI technique is effective in treating mild to moderate hallux valgus in terms of relief from symptoms and functional improvement. This technique allowed correction of the main parameters of the deformity, with durable clinical and radiographic results at a mid-term follow-up.

All of the techniques were effective in achieving good clinical and radiographic results in patients with osteochondritis dissecans, and the effectiveness of autologous chondrocyte implantation was confirmed at a mean follow-up of five years. Newer techniques such as MaioRegen implantation and the "one-step" transplantation technique are based on different rationales; the first relies on the characteristics of the scaffold and the second on the regenerative potential of mesenchymal cells. Both of these newer procedures have the advantage of being minimally invasive and requiring a single operation.

BackgroundCervical degenerative pathology produces pain and disability, and if conservative treatment fails, surgery is indicated. The aim of this study was to determined whether anterior decompression and interbody fusion according to Cloward is effective for treating segmental cervical degenerative pathology and whether the results are durable after a 10-year-minimum follow-up.Materials and methodsFifty-one patients affected by single-level cervical degenerative pathology between C4 and C7 were surgically treated by the Cloward procedure. Clinical evaluation was rated using the Neck Disability Index (NDI) and the visual analog scale (VAS). At last follow-up, the outcomes were rated according to Odom’s criteria. On radiographs, the sagittal segmental alignment (SSA) of the affected level and the sagittal alignment of the cervical spine (SACS) were measured.ResultsAverage NDI was 34 preoperatively and 11 at last follow-up. Average VAS was 7 preoperatively and 1 at last follow-up. According to Odom’s criteria, the outcome was considered excellent in 18 cases, good in 22, and fair in 11. Average SSA was 0.5 ± 2.1 preoperatively, 1.8 ± 3.8 at 6 months, and 1.8 ± 5.7 at last follow-up. Average SACS was 16.5 ± 4.0 preoperatively, 20.9 ± 5.8 at 6 months, and 19.9 ± 6.4 at last follow-up. Degenerative changes at the adjacent levels were observed in 18 patients (35.3%).ConclusionsThe Cloward procedure proved to be a suitable and effective technique for treating segmental cervical degenerative pathology, allowing good clinical and radiographic outcomes even at a long-term follow-up.
