Aims: We compared treatment with external fixation (EF) vs DHS in osteoporotic trochanteric fractures. Methods: 40 patients were randomized to receive either 135° 4-hole DHS (Group A) or an Orthofix trochanteric external fixator with 4 hydroxyapatite-coated Osteotite pins (Group B). Inclusion criteria were: female, age ≥65 years, AO fracture type A1-2 and BMD lower than -2.5T score. Fixators were removed at 3 months. Results: There were no differences in patient age, fracture type, BMD, ASA, hospital stay, or quality of reduction. Operative time was 64±6 minutes in Group A and 34±5 minutes in Group B (p< 0.005). Average number of blood transfusions was 2±0.1 in Group A, and none in Group B (p< 0.0001). Fracture varization at 6 months was 6±8° in Group A and 2±1° in Group B (p=0.002). Harris Hip Score was 62±20 in Group A and 63±17 in Group B (ns). In Group B, no pin-track infections occurred. Pin fixation was maintained over time, as shown by no differences between pin extraction and insertion torque. Conclusions: We consider EF a viable treatment option for this patient population. Operative time is short, postoperative complications are minimized, and fixation is improved.

Aims: The purpouse of the study is to review a series of hallux valgus treated by minimally invasive distal metatarsal osteotomy with a simple, effective, rapid, inexpensive (SERI) technique. Methods: 54 consecutive feet in 37 patients, aged 48 ± 23 years affected by hallux valgus deformity less than 40û with an intermetatarsal angle up to 20û were reviewed at 5 years follow up. Surgical technique consisted of a 1 cm medial incision at the metatarsal neck, then an osteotomy was performed using an oscillating saw. With a direct line of vision, all characteristics of the deformity (HVA, IMA, DMAA) were corrected by lateral displacement of the metatarsal head; contemporary plantar or dorsal displacement was performed according to insufþciency or overloading of the þrst ray. The osteotomy was stabilized by a 2 mm Kirschner wire. All patients were clinically (AOFAS score) and radiographically checked at an average follow up of 5 years. Results: The clinical score at follow up was (91±12). The pre-op hallux valgus angle was 32.5±9, while post-op it was 22±7 (p< 0.0001), pre-op inter-metatarsal angle was 13±3, while post op it was 9±3 (p< 0.0001), the pre-op distal metatarsal articular angle was 19±10, while post-op it was 9±7 (p< 0.0001). Conclusions: Clinical and radiographic þndings showed that SERI osteotomy permitted an adequate correction of all the pathologic characteristics of the deformity, and this factor is responsible for our satisfactory results.
