ABSTRACT
PURPOSE: To correlate clinical results to magnetic resonance imaging (MRI) and arthroscopy after cryopreserved nontissue-antigen-matched meniscal transplantations. TYPE OF STUDY: Blinded; the observers were blinded for each others' assessment. MATERIALS AND METHODS: Sixteen consecutive patients were included in the protocol. First, clinical evaluation and MRI were performed. Second, within 24 hours, arthroscopy was performed. RESULTS: The clinical results showed better correlation between clinical results and arthroscopy than between clinical results and MRI. In the present study, MRI was not beneficial in evaluating meniscal transplants. CONCLUSIONS: Using more sophisticated MRI techniques, the correlation between clinical results, arthroscopy, and MRI could probably be improved.

STUDY OBJECTIVE: To assess the late complications of percutaneous dilatational tracheotomy, particularly the incidence of tracheal stenosis and voice changes. DESIGN: Prospective descriptive clinical study. SETTING: Teaching hospital, the Netherlands. PATIENTS: Eighty consecutive patients who were successfully decannulated after percutaneous tracheotomy. MEASUREMENTS AND RESULTS: Fourteen patients died after decannulation, of tracheotomy-unrelated causes. Sixty-six patients were followed up 3 to 39 months after decannulation (mean, 16 months). Fifty-four patients underwent tomography of the trachea. In 14 patients (26%), there was tracheal narrowing of more than 10%. Data analysis showed that these stenoses were operator dependent (p = 0.03). Voice changes, found in 13 (21%) of 61 patients, were major in 1 and minor in 12. Scars were generally cosmetically acceptable. Retraction of the scar, seen in 13 (19%) of 66 patients, was related to the duration of cannulation (p = 0.002). A persistent tracheocutaneous fistula was present in two patients. CONCLUSIONS: The incidence of tracheal stenosis after percutaneous dilatational tracheotomy is low compared with conventional tracheotomy. Experience with the technique is important to avoid late complications.

The case reports of three patients with carpometacarpal dislocations are described. The diagnosis of this condition may be difficult and is often missed. Swelling, dislocation and a palpable lump are the main clinical findings. X-ray findings, the key to the diagnosis, are loss of parallelism, interruption of the so-called M-line and overlapping of articular surfaces. Additional X-rays in different planes are to be recommended if carpometacarpal dislocation is suspected.
