Simultaneous ipsilateral Monteggia fracture-dislocation and distal radius fracture: A report of a pediatric case and review of the literature.

We present the case of a 12-year- old boy who suffered from a combination of Monteggia fracture-dislocation along with ipsilateral distal radius fracture. The patient underwent closed reduction of the Monteggia lesion and the distal radius followed by percutaneous pinning. The postoperative course was satisfactory.

Radiocapitellar cartilage injuries associated with tennis elbow syndrome.

Purpose: A recent anatomical study has suggested that considerable contact between the undersurface of the extensor carpi radialis brevis (ECRB) and the lateral edge of the capitellum is the cause of tendon injury in lateral epicondylosis. We hypothesized that this contact might concurrently induce cartilage injuries of the capitellum. The purpose of the present study was to determine the prevalence, location, and severity of cartilage lesions of the radiocapitellar joint accompanying lateral epicondylosis and to identify their correlation with ECRB status.

New method of assessing pinch function in children with anomalies of the hands.

We designed a method for the evaluation of pinch function in children that uses a tape measure, which is suitable in size and weight for the infant's hand. Our aim was to investigate the value of the tape measure in the evaluation of pinch function in children. Thirty-two hands of 27 children with congenital anomalies that we operated on in our hospital were included.

The detection of the capsular tear at the undersurface of the extensor carpi radialis brevis tendon in chronic tennis elbow: the value of magnetic resonance imaging and computed tomography arthrography.

Hypothesis: This study compared the diagnostic efficacy of magnetic resonance imaging (MRI) and computed tomography arthrography (CTA) in the assessment of capsular tears at the undersurface of the extensor carpi radials brevis tendon in chronic tennis elbow using arthroscopy as a gold standard. Because of the higher spatial resolution of CT, we hypothesized that CTA is superior to MRI for assessing capsular tears.

Materials And Methods: We retrospectively reviewed 19 consecutive patients with chronic tennis elbow with preoperative MRI and CTA studies who underwent arthroscopic surgery.

Cup-neck impingement due to the malposition of the implant as a possible mechanism for metallosis in metal-on-metal total hip arthroplasty.

The metal-on-metal bearing total hip prosthesis is expected to reduce the risk of debris-related osteolysis. However, several reports demonstrated that the socket-stem impingement in the metal-on-metal prosthesis due to the implant malposition results in titanium wear debris and secondary metallosis. In this article, we presented a case of massive metallosis due to metal-on-metal impingement.
