After a severe ankle sprain, the incidence of residual complaints, particularly on the medial side of the joint, is high. We experienced a case of medial impingement between medial malleolus and anteromedial osteophyte of talus, specially in the dorsiflexion of the right ankle. Twenty five-year-old male was complained tenderness and chronic pain over the medial side of the right anklel for 3 years after an inversion sprain of the ankle. The plain radiography revealed a bony osteophyte on the anteromedial side of talus. The patient was treated by the open arthrotomy of the ankle. At surgery, impingement between articular surface of medial malleolus and osteophyte of the talus was observed when ankle dorsiflexion was done. Chondral lesion of medial malleolus and chondromalacic degeneration on anteromedial talus was viewed. Surgical removal of osteophyte on talus and debridement and multiple drilling of chondral lesion on medial malleolus was done. The symptom was improved. After postoperative 1 year, recurrence was not.

A 3-year-old, 5.6 kg, castrated, male, British short hair cat presented with subtle weight-bearing lameness of the right hindlimb when walking suddenly after rest. On physical examination, the patient experienced pain when the right stifle joint was hyperextended. There was no clinical improvement of lameness or pain of the right hindlimb, despite the administration of analgesic drugs for one week. During diagnostic arthroscopy of right stifle, mild synovitis and cranial cruciate ligament (CCL) impingement on osteophyte of the intercondylar notch (ICN) was observed. Computed tomography was applied to determine an accurate surgical plan. Arthroscopy-assisted notchplasty, including removal of the osteophyte, was performed using chisel and arthroscopic burr. At 4 weeks postoperatively, the frequency of subtle weight-bearing lameness of the right hindlimb was significantly reduced. At 6 months postoperatively, the patient exhibited normal ambulation without recurrence of lameness. Impingement of CCL may cause subtle lameness and pain. Arthroscopy can be a good diagnostic tool for early-stage CCL disease. Notchplasty can be recommended for osteophyte-induced CCL disease.

Purpose : The purpose of this study is to compare radiographic techniques for the diagnostic accuracy in the detection of osteophytes of the mandibular condyle. Material and Methods : A series of bone chips were placed at four locations on the condylar head of a dried human skull. Eight radiographic techniques such as panoramic, transcranial, infracranial, transorbital, reverse-Towne's, submentovertex, multidirectional tomographic and computed tomographic techniques were compared. Three oral radiologists were asked to rate the lesions by four stage score. The statistical analysis was performed by ANOVA test. Results: For the detection of lateral osteophyte, transcranial, infracranial, transorbital and reverse-Towne' s views showed superiority. Also, transcranial and infracranial views showed superiority for medial osteophyte. While for the detection of superior and anterior osteophyte, panoramic, transcranial, infracranial, transorbital views showed superiority. Lateral tomograph showed superiority for the detection of superior and anterior osteophyte, but it showed inferiority for lateral and medial osteophyte. And antero-posterior tomograph showed superiority for the detection of all osteophytes. Axial computed tomograph showed superiority for the detection of all osteophytes, and coronal computed tomograph showed superiority for lateral, medial and superior osteophytes. While reconstructed sagittal computed tomograph showed relatively superiority for the detection of anterior and superior osteophytes. Conclusion : The conventional radiographs can be used for the detection of bony changes of the mandibular condyle, and tomograph or computed tomograph can be used additionally when it is difficult to detect bony changes on conventional radiographs.

Objective : Various procedures have been introduced for anterior interbody fusion in degenerative cervical disc disease including plate systems with autologous iliac bone, carbon cages, and cylindrical cages. However, except for plate systems, the long-term results of other methods have not been established. In the present study, we evaluated radiologic findings for cylindrical cervical cages over long-term follow up periods. Methods : During 4 year period, radiologic findings of 138 patients who underwent anterior cervical fusion with cylindrical cage were evaluated at 6, 12, 24, and 36 postoperative months using plain radiographs. We investigated subsidence, osteophyte formation (anterior and posterior margin), cage direction change, kyphotic angle, and bone fusion on each radiograph. Results : Among the 138 patients, a minimum of 36 month follow-up was achieved in 99 patients (mean follow-up : 38.61 months) with 115 levels. Mean disc height was 7.32 mm for preoperative evaluations, 9.00 for immediate postoperative evaluations, and 4.87 more than 36 months after surgery. Osteophytes were observed in 107 levels (93%) of the anterior portion and 48 levels (41%) of the posterior margin. The mean kyphotic angle was $9.87^{\circ}$ in 35 levels showing cage directional change. There were several significant findings : 1) related subsidence [T-score (p=0.039) and anterior osteophyte (p=0.009)], 2) accompanying posterior osteophyte and outcome (p=0.05). Conclusion : Cage subsidence and osteophyte formation were radiologically observed in most cases. Low T-scores may have led to subsidence and kyphosis during bone fusion although severe neurologic aggravation was not found, and therefore cylindrical cages should be used in selected cases.

Purpose: The purpose of this study was to evaluate the correlation between the clinical symptoms of temporomandibular disorder and findings in the magnetic resonance imaging (MRI). Materials and Methods: Clinical data and MRI images were collected from a total of 240 German patients. Clinical symptoms were briefed as joint clicking, crepitus and pain. MRI findings were further defined according to the condyle position, condyle degeneration, disc positon, disc degeneration and the presence of osteophyte/sclerosis/synovitis. Hypermobility was separately recorded. Correlation analysis between parameters was performed. Result: Joint clicking had a positive correlation with unilateral disc degeneration, osteophyte, sclerosis and synovitis. Crepitus had a significant correlation with bilateral osteophyte. Pain was not correlated with any MRI findings except hypermobility. Conclusion: Selective correlations between the MRI findings and clinical symptoms were elucidated. The results of this study imply that condyle-disc deformities could be advanced without pain, and that joint clicking and crepitus could be clinical symptoms of condyle-disc degeneration.

Spontaneous rupture of the extensor tendon has been reported in association with predisposing inflammatory conditions including rheumatoid arthritis, diabetes, trauma, tophaceous gout, and steroid injection. The authors experienced a case of spontaneous rupture of the extensor digitorum longus tendons caused by an osteophyte of the tarsometatarsal joint in a patient with rheumatoid arthritis. The authors stress that aggressive treatment including surgery could be considered for prevention of spontaneous tendon rupture in a patient with predisposing conditions despite an asymptomatic spur.

Purpose: We analyzed the ankle bony abnormality of patients with marked ankle instability who had chronic ankle sprain more than 3 years. Materials and Methods: We evaluated the chronic ankle sprain (more than 3 years) patients with marked ankle instability tested by varus stress test and anterior draw test from March 2000 to December 2005. Eighty-nine patients (104 ankle) were evaluated and there were 38 males and 51 females. The mean age of patient at the time of diagnosis was 34.5 (range, 18 to 56 years). The average duration of morbidity was 7 years and 3 months (range, 3 years and 3 months to 21 years). The patients who had history of dislocation, fracture, malalignment, operated patients, and rheumatoid ones were excluded. Plain radiographs of AP, lateral, oblique and mortise view were checked. Results: Radilologic abnormalities were found at 74 ankles (71%) among 104 ankles. Frequent sequences of location were anterior talotibial osteophyte, medial malleolar osteophyte, Os subfibulare, lateral malleolar osteophyte. Posteior osteophyte, ankle arthritis, talar articular defect were rarely found. Conclusion: Seventy-one percent among patients with chronic ankle sprain and marked ankle instability showed more than one radiologic abnormalities. Thus, more exclusive and accurate ankle examination should be performed in these patients.

Impingement syndrome is caused by a conflictual status between rotator cuff, subacromial bursa and anatomic and functional coracoacromial arch. The purpose of this study was to assessment the coracoacromial arch by MRI and to determine major factors among five components of coracoacromial arch. We analyzed forty-two cases of clinical impingement sign and test positive and postoperative confirmed diagnosed from March, 1991 to January, 1999. We evaluated acromial end abnormality according to the Bigliani acromial type and formation of osteophyte. Clavicular end abnormality classified flat, outward protrusion, inward protrusion to coracoacromial arch. Acromioclavicular joint abnormalities were advanced osteoarthritis and positive signal change. Coracoacromial ligament thickening was above 2 mm in oblique sagittal image. Coracoid process abnormality was inward protrusion to coracoacromial arch. All consecutive patients abnormalities were as follows: clavicular end osteophyte formation and inward protrusion to coracoacrmial arch were 30%, acromial end osteophyte formation was 28%, advanced acromioclavicular joint arthritis and osteophyte formation were 56%, coracoacromial ligament thickening was 24% and no coracoid process inward protrusion to coracoacromial arch. Impingement syndrome combined with rotator cuff tear group abnormalities were clavicular end(40%), acromial end(40%), acromioclavicular joint(20%), coracoacromialligament(20%) and coracoid process abnormality(0%) respectively. Only impingement syndrome group abnormalities were clavicular end(25%), acromial end(31%), acromioclavicular joint(62%), coracoacromial ligament(25%) and coracoid process(0%) respectively. Acromial type I(flat) were 6 cases, type II(curved) were 26 cases and type III(hooked) were 10 cases. We concluded that the most important contributing factors for impingement syndrome was acromial type and second was acromioclavicular joint arthritis and bony spur formation.
