This study was designed to reveal the correlationship between the internal derangement state of TMJ and clinical characteristics including pain and mandibular dusfuntion. One hundred and twenty five subjects with TMJ signs and symptoms were chosen for two years. The level of pain and mandibular dysfuntion were evaluated by Visual Analog Scale(VAS) and Craniomandibular Index(CMI). The diagnostic categories of TMJ internal derangement were determined by arthrography and they included normal disc position, anterior disc displacement with reduction(ADDR), rotational disc displacement with reduction(RDDR), andterior disc displacement without reduction(ADDNR), and rotational disc displacement without reduction(RDDNR). Also disc perforation was used as a criteria to divide the diagnostic subgroups. The obtained results were as follows ; 1. The patient distribution of each group was 5 in normal disc position(4%), 40 in ADDR(32%), 30 in RDDR(24%), 34 in ADDNR(27%), and 16 in RDDNR(13%). 2. Perforation was observed in 8% of ADDR, 10% of RDDR, 32% of ADDNR, and 19% of RDDNR. 3. CMI of perforation group was higher than that of reduction or normal group(P<0.005), but vas showed no significant difference. 4. CMI of non-reduction group was higher than that of non-perforation group in reduction group(P<0.05). 5. There were no significant differences of CMI and VAS between anterior disc displacement group and rotational disc displacement group in both reduction and non-reduction group. 6. CMI of RDDNR group was higher than that of RDDR group(P<0.05). 7. There were no significant difference of CMI and VAS between bilateral involvement group and unilateral involvement group(p>0.05).

Double contrast arthrography has been widely accepted as a method to diagnose the internal derangement of the knee. It is a safe and technically simple procedure permitting accurate diagnosis of lesions of the menisci. In 20 cases operated upon, with the diagnosis of internal derangement of the knee, we performed double contrast arthrography before surgery. We analysed the cases concerning the diagnostic accuracy of arthrography, its clinical significance and discrepancies between arthrographic findings and postoperative lesions. The results were as follows: 1. The cases consisted of 16 cases of meniscal lesion, 4 cases of ligamentous lesion and 3 cases of loose body. 2. In the meniscal lesions, 14 of the 16 cases (87.5%) were diagnosed accurately by arthrography, Therefore arthrography was more useful in diagnosing meniscal lesions as compared with clincal symptoms (69%). 3. In cases of ligamentous lesions arthrography was not significant-ly helfpful, in contrast clinical signs afforded important clues. 4. We encountered 1 case of false positive and 1 case of false negative.

The value of double contrast arthrography in meniscal lesions was studied in 58 patients with clinical findings suggestive of meniscal lesion. In all cases, arthrotomy was performed and meniscal lesions were found in 52 patients. The arthrographic findings were compared to clinical and operative findings and the following results were obtained. 1. The diagnostic accuracy of arthrography in meniscal lesions was 84.5% 2. The diagnostic accuracy of the clinical findings was 69%, but the accuracy was increased to 91.4% with the aid of arthrographic findings. 3. Arthrography would be unnecessary if the clinical findings highly suggest the meniscal lesion. 4. Arthrography is thought to be a useful diagnostic method for meniscal lesions.

PURPOSE: The purpose of the study is to evaluate the usefulness of CT arthrography (CTA) by conducting a comparative study of CTA and MR arthrography (MRA) with the arthroscopic findings in the same patients. MATERIALS AND METHODS: Forty nine patients who suffered from shoulder disease underwent MRA and CTA concurrently. The sensitivity and specificity of CTA was evaluated, as compared to MRA, in the case of four types of shoulder pathological lesions. The accuracy of CTA was evaluated by analyzing the arthroscopic findings of thirty four patients. RESULTS: Compared to MRA, CTA showed a sensitivity of 90% and a specificity of 100% for diagnosing supraspinatus tendon (SST) full thickness tear, and CTA showed a sensitivity of 100% and a specificity of 97.5% for making the diagnosis of superior labrum anterior to posterior (SLAP) lesion. For diagnosing partial articular side supraspinatus avulsion (PASTA) lesion, some studies have shown the usefulness of CTA with a sensitivity of 71.4% and a specificity of 97.7%. However, for diagnosing SST bursal side partial tear, the sensitivity of CTA was as low as 10%. CTA has been shown to be relatively accurate when the diagnoses were verified with the arthroscopic findings; diagnosing SST full thickness tear and SLAP lesion with CTA has shown an accuracy of 100% and87.5% respectively, and CTA showed 71.4% diagnostic accuracy for PASTA lesion. CONCLUSION: CTA was a useful tool and it was equivalent to MRA for the assessment of SST full thickness tear, SLAP lesion and PASTA lesion, but not bursal side partial tear. Thus, it may be used preferably to diagnose shoulder pathology and for follow up as an inexpensive tool after operation.

PURPOSE: This study was performed to evaluate the presence and severity of Hill-Sachs (HS) lesions on MR arthrography (MRA) of shoulder in patients with Bankart lesions following anterior dislocation and to investigate their relationship with Bankart lesions and frequency of dislocations. MATERIALS AND METHODS: 86 MRA of shoulder were evaluated in patients with arthroscopic Bankart repairs following anterior dislocations. The largest surface length of HS lesion on MRA and extent of Bankart lesions on arthroscopy were measured. Relationships between length of HS lesions and extent of Bankart lesions and frequency of dislocations were assessed. RESULTS: HS lesions were identified on MRA in 78 patients. The largest surface length of HS lesion ranged from 9.3 mm to 29.6 mm (mean, 18.8 mm). The extent of Bankart lesion ranged from one to six o'clock extent (mean, 4.25 o'clock extent). Three patients had single dislocation and the other 75 patients had recurrent dislocations (mean 24.5 times). The largest surface length of HS lesions was positively correlated with extent of Bankart lesions (p = 0.001, r = 0.37), but not with frequency of dislocation. CONCLUSION: HS lesion was very common in patients with Bankart lesion. The severity of HS lesions was correlated with extent of Bankart lesions.

10.Ankle Impingement Syndrome.

Journal of Korean Foot and Ankle Society 2012;16(1):19-25
The ankle impingement syndrome is an established cause of ankle dysfunction. In most cases with suspected ankle impingement, the diagnosis can be possible on the basis of mechanism of injury involved and the clinical examination. An appropriate imaging study should be selected where clinical doubt about the exact diagnosis exists. Radiography plays an important role in the initial assessment of these conditions, especially in anterior and posterior impingement. Magnetic resonance arthrography seems to be the most accurate means of assessing the capsular abnormalities present in anterolateral and anteromedial impingement and for confirmation of possible concomitant injury. Surgical treatment can be considered for the patients who did not respond to conservative treatment for more than 6 months, and has a low complication rate and a high level of success.
