[Patella cubiti detected after a trauma: about a case and literature review]. / La patella cubiti découverte à la suite d'un traumatisme: à propos d'un cas et revue de la littérature.

Patella cubiti is a very rare anomaly characterized by the non-union of olecranon and proximal ulna. We here report the case of a 27-year old patient admitted with a trauma of the elbow. Diagnostic examination revealed patella cubiti mimicking olecranon fracture. The patient underwent excision of bone fragment. Three months after surgery, the patient was satisfied because the foreign body that he felt at the level of the elbow had disappeared.

[Hip arthroscopy in patients with femoroacetabular impingement: about 2 cases]. / L'arthroscopie de la hanche dans le conflit fémoro-acétabulaire: à propos de 2 observations.

Femoroacetabular impingement (FAI) can causes hip pain in young subjects and in athletes. His diagnosis is based on clinical and radiological examinations. Surgical treatment is based on conventional surgery or on arthroscopy. Arthroscopy proves to be a reliable technique in the treatment of FAI. It is effective on the pain and improves performances of athletes in order to enable them to resume their activities within a very short space of time. We here report our experience within our Department in treating 2 patients with FAI with arthroscopy. Modified Harris score significantly improved at the last follow-up (24 and 18 months).

[Spontaneous simultaneous bilateral rupture of the quadriceps tendon in patients with parathyroid adenoma: case report and literature review]. / Rupture bilatérale spontanée et simultanée du tendon quadricipital dans l'adénome parathyroïdien: à propos d'un cas et revue de la littérature.

Spontaneous as well as bilateral and simultaneous rupture of the quadriceps tendon is rare. We report the case of a 53-year old patient followed up for parathyroid adenoma complicated by renal failure, admitted for spontaneous bilateral rupture of the two quadriceps tendons. He underwent surgical repair allowing him to maintain his autonomy.

Bone pathologic fracture revealing an unusual association: coexistence of Langerhans cell histiocytosis with Rosai-Dorfman disease.

BACKGROUND: The coexistence of Rosai-Dorfman disease (RDD) with Langerhans cell histiocytosis (LCH) is very rare, as to date only 17 cases have been reported in the english literature. The pathophysiology of this uncommon co-occurrence still remains enigmatic and a subject of various speculations. CASE PRESENTATION: We report a case of a 30-year-old female patient who presented with a pathologic fracture of the left proximal femur. Her medical history was unremarkable, there were no fever, skin lesions, lymphadenopathy or other organomegaly at physical examination. X-ray radiograph of the fractured femur showed an isolated and ill-defined osteolytic lesion. The histopathological analysis of biopsies from this lesion were consistent with a combined RDD-LCH of the bone. CONCLUSION: Combined RDD-LCH is a very rare phenomenon, whose pathophysiology still remains unclear and a subject of various speculations.

Ulnar nerve entrapment complicating radial head excision.

INTRODUCTION: Several mechanisms are involved in ischemia or mechanical compression of ulnar nerve at the elbow. PRESENTATION OF CASE: We hereby present the case of a road accident victim, who received a radial head excision for an isolated fracture of the radial head and complicated by onset of cubital tunnel syndrome. This outcome could be the consequence of an iatrogenic valgus of the elbow due to excision of the radial head. Hitherto the surgical treatment of choice it is gradually been abandoned due to development of radial head implant arthroplasty. However, this management option is still being performed in some rural centers with low resources. DISCUSSION: The radial head plays an important role in the stability of the elbow and his iatrogenic deformity can be complicated by cubital tunnel syndrome. CONCLUSION: An ulnar nerve release was performed with favorable outcome.
