Open from Monday (from 7 a.m.) through Friday (until 6 p.m.) has 12 beds available. This Organisation Unit hosts patients that need surgical treatment for pathologies concerning movement organs of non-acute traumatic origin. Examples: Shoulder pathologies (instability, lesions to the rotator muscles cuff, friction syndrome, shoulder arthroscopy, etc.). Knee pathologies (arthroscopy, cartilaginous, ligament and meniscal lesions, femur and tibial osteotomy). Foot pathologies (can be performed in Day Hospital or in One Day Surgery). Traumatic after-effects: pseudoarthrosis, removal of osteosynthesis instruments. Moreover, this section also hosts: Traumatic pathologies that do not require urgent and immediate surgery, that is operations that can be postponed for a few days: for instance, the fracture of peripheral skeletal fragments (clavicle fracture, simple malleolar fracture), sub-cutaneous tendon lesions, etc. Some pathologies that do not require surgery: hospitalisation following traumatisms that require a continuation of the treatment in the hospital. However, these are selected or particular cases the number of which has been decreasing greatly compared to the past. In any case, the Short Orthopaedic Hospitalisation Sector hosts only scheduled hospitalisations. Inside the S.O.H.S. you will also find the Day Hospital sector (with another 3 beds). However, this section does not include the Arthroprosthesis Sector (hip, knee and shoulder), since the hospitalisation time such surgery requires is over 5 days. The good functioning of this sector requires a detailed programming of the different types of surgery to be performed, based on the day of the week: the kinds of surgery that require longer post-operative hospitalisation times (4-5 days) will obviously be scheduled on Mondays, whereas Arthroscopic surgery and other kinds of little surgery will instead be performed on Fridays. Apart from midweek holidays that are celebrated on Mondays or Fridays, the Short Hospitalisation Organisation Unit will remain open. Transfers from the short orthopaedic hospitalisation sector to the ordinary hospitalisation sector are to be considered exceptional cases, since the indicated pathologies -except when complications linked to the clinical conditions arise- require a hospitalisation period of less than 5 days. The Short Hospitalisation Sector will also be closed during major holidays, and all the programmed surgeries will be discontinued; in 2001 the Sector remained closed during the whole month of August and during Christmas time. Thanks to this kind of organisation, the U.O. staff members were able to regularly schedule their own vacation time.
