[Pyoderma gangrenosum after orthopedic conservative treatment].

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis. Half of the cases are associated with an immune dysfunction and are frequently triggered by pathergy such as a tissular aggression via surgery or burn wounds. A patient with ulcerative colitis presented a PG at the site of an iontophoresis patch for tendinopathy.

[An «all around» version of the Mac Gregor free flap].

Given the appearance of a good number of cover flaps in recent decades, the Mac Gregor flap in its free form is used less and less but still finds its place today in certain complex cases with extensive loss of substance. This report describes an unusual case of wide tissue coverage by «all around» flap by Mac Gregor technique in a victim of an extensive burn of the left upper limb which occurred on 08/08/1997 and was responsible for a progressive flessum of the wrist and a hyperextension of the fingers with a complete loss of their mobility. The intervention is done in one step with a wide release of the scarred areas of the wrist and hand and the realization of the free inguinal flap in «all around».

[Efficacy comparison of conservative and surgical treatment in proximal humerus fractures : a monocentric retrospective study].

Proximal humerus fractures (PHF) are common, they represent 4 to 6 % of all fractures. They usually affect the elderly (above 60 years) and most the time, women (M/F ratio = 3/7). In general, they are not or slightly displaced and their treatment is thus commonly conservative (75 to 90 % of cases).

Evaluation of commercially available point-of-care ultrasound for automated optic nerve sheath measurement.

Background: Measurement of the optic nerve sheath diameter (ONSD) via ultrasonography has been proposed as a non-invasive metric of intracranial pressure that may be employed during in-field patient triage. However, first responders are not typically trained to conduct sonographic exams and/or do not have access to an expensive ultrasound device. Therefore, for successful deployment of ONSD measurement in-field, we believe that first responders must have access to low-cost, portable ultrasound and be assisted by artificial intelligence (AI) systems that can automatically interpret the optic nerve sheath ultrasound scan.

[Aseptic loosening due to osteolytic reaction to polyethylene of o total knee prosthesis].

Total knee replacement (TKR) is currently the gold standard in the surgical management of degenerative knee diseases. It is a reliable operation with 95 % good results at 10 years after surgery. Aseptic loosening is the primary cause of TKR failure.
