About a new entity in the coronal shear fracture of the distal humerus: Broberg-Morrey's fracture with Laugier's fracture in the same elbow.

Coronal shear fractures of the distal humerus involving only the capitellum or the trochlea are rare injuries. Their combination has rarely been described. Herein, we report the case of a 39-year-old man who presented with pain and total functional impotence in his right elbow following a fall; the clinical and radiological findings revealed a new entity in the coronal shear fractures of the distal humerus, which included a comminuted fracture of the capitellar and displaced separate trochlea in the same elbow. This fracture was treated surgically with a good outcome at the last follow-up.

An unusual cause of tarsal tunnel syndrome: Schwannoma of the posterior tibial nerve; a rare cause and rare localization.

INTRODUCTION: Schwannoma of the posterior tibial nerve is extremely rare. CASE PRESENTATION: A 25-year-old female with a one-year history of left foot pain is presented. Clinical and radiological findings were in favor of a tarsal tunnel syndrome caused by a schwannoma of the posterior tibial nerve, prompting the patient to undergo surgery. We performed a complete excision of the tumor with the aid of a loupe magnification. At the last follow-up, the patient did well, with no recurrent pain and no neurological squeals. DISCUSSION: The diagnosis of a tibial nerve schwannoma can often be difficult as, in the early stages, a mass may not be palpable and symptoms are often non-specific because of the slow-growing soft tissue mass. CONCLUSION: Although schwannoma is a rare cause of tarsal tunnel syndrome, it should be kept in mind by physicians, especially in cases of chronic unexplained foot pain with a positive Tinel's test.
