A new hinged dynamic distractor, for immediate mobilization after knee dislocations: Technical note.

Knee dislocation is always a difficult topic mainly with regard to the structures that have been damaged and the best treatment option. The purpose of this study is to describe a new dynamic external fixator (EF) to be applied after knee dislocation, in combination with posterior cruciate ligament (PCL) reconstruction. This approach permits an immediate postoperative mobilization of the joint, with the possibility to perform a delayed ACL reconstruction and eventually reducing the complication rate related to multiple ligament surgery.

Primary lymphocutaneous nocardiosis in an immunocompetent patient.

BACKGROUND: Nocardia brasiliensis is a rare human pathogen usually associated with localized cutaneous infections. CASE PRESENTATION: We report a case of primary lymphocutaneous Nocardia brasiliensis infection developed after a bone fracture of the left hand of an otherwise healthy 32-year-old man. Treatment with trimethoprim-sulfamethoxazole given for a total of three months combined with surgical debridement resulted in complete resolution of the infection. CONCLUSION: Nocardiosis should be part of the differential diagnosis in patients with sporotrichoid infection, particularly those with a history of outdoor injury. Culture of the affected tissue and antimicrobial susceptibility testing of the isolate should be performed for diagnosis and treatment.
