[Hoffa's disease].

We report the case of a 40-year female patient, with no previous pathological history, presenting with right unilateral mechanical gonalgias with progressive onset, which increased climbing and going down stairs associated with hydarthrosis on clinical examination. After normal standard X ray, MRI showed a grease of hypertrophied Hoffa's grease with heterogeneous hyposignal on T1 (A), hypersignal on T2 with grease saturation (B), heterogeneously enhancing after gadolinium injection. The diagnosis of Hoffa's disease was made and the patient, after failure of a medical treatment, underwent arthroscopy for ablation of the Hoffa's grease with good evolution.

[Treatment of humerus diaphyseal fractures using Hackethal's retrograde centro-medullary bundle nailing: about 54 cases].

We here report 54 cases of humerus diaphyseal fractures treated via Hackethal's bundle nailing. We observed 3 cases of radial nerve palsy. Therapeutic abstention associated with monitoring was the applied attitude toward these patients on presentation to the Emergency Department.
