Macrodystrophia Lipomatosa of the Foot (A Case Report) / 대한족부족관절학회지

Macrodystrophia lipomatosa is a congenital macrodactyly characterized by progressive overgrowth of all the mesenchymal elements of a digit or digits with a disproportionate increase in the fibroadipose tissue. We reported a case of macrodystrophia lipomatosa of the foot, which is a rare case, and reviewed the literatures.

Treatment of the Posterior Malleolar Fragment of Trimalleolar Fracture Using Posterolateral Approach: Preliminary Report / 대한정형외과학회잡지

PURPOSE: We wanted to evaluate the effectiveness of posterolateral approach for open reduction and internal fixation of posterior malleolar fragment with trimalleolar fracture of ankle joint. MATERIALS AND METHODS: There were 27 cases of trimalleolar fracture in our hospital from Jan. 2005 to Dec. 2007. We investigated 10 patients who underwent operation with the posterolateral approach. The mean follow up period was 20 (6-36) months. Preoperative posterior malleolar fragment involved above 25% of articular surface in 10 cases and displaced more than 2 mm in 4 cases. We analyzed the radiologic type of posterior malleolar fragments and complications, and evaluated the AOFAS score. RESULTS: All cases showed primary union mean 11.8 (8-14) weeks. The complication focal skin necrosis in one case and all patients showed excellent AOFAS score. CONCLUSION: The posterolateral approach may be a useful for open reduction and internal fixation of posterior malleolar fragment with trimalleolar fracture, especially simultaneous management of lateral malleolar fracture.

Normal Glenoid Size of the Korean in 7th and 8th Decades

PURPOSE: We wanted to evaluate the normal glenoid size of Koreans in their 7th and 8th decades by conducting Computed tomographic (CT) studies. MATERIALS AND METHODS: The CT images were obtained from the normal scapulae of the patients (mean age: 68.8) who had humeral fracture. A display workstation version 2.0.73.315 was used to measure the scans to determine the maximal superoinferior (SI) and anteroposterior (AP) diameters of the glenoid vault. RESULTS: The average diameters of curvature of the glenoid were 31.2 mm (range: 27 to 34 mm) in the superior-inferior direction and 26.1mm (range: 22 to 31mm) in the anterior-posterior direction. CONCLUSION: This study showed the normal glenoid size of Koreans and it is different from the size that the international literature reported. It should be an important factor for the treatment of fracture or in designing arthroplasty implants.

The Factors associated with Postural Control after Anterior Cruciate Ligament Reconstruction

PURPOSE: We analyzed the correlation of the Lysholm score, anterior displacement of tibia on stress radiography and muscle strength around the knee with postural control after anterior cruciate ligament reconstruction and also compared them with the normal subjects. MATERIALS AND METHODS: Twenty-five patients after ACL reconstruction were evaluated with Lysholm knee score, anterior displacement on stress radiography with Telos, muscle strength around the knee with Biodex dynamometer and postural control with posturography. RESULTS: The postural control had significant correlation with the Lysholm knee score & anterior displacement on stress radiography(r=0.565, r=0.783, p0.05). Patients group with 5mm instability under anterior displacement on stress radiography showed no significance compared with normal control group, while the group with instability more than 6mm showed significant differences in some conditions com- pared with control group. CONCLUSION: Postural control after ACL reconstruction have significant correlation with Lysholm score and we presumed that the acquisition of mechanical stability of the knee after ACL reconstruction may be one of the important factors associated with the recovery of postural control by improvement of the proprioception.

Balance in Patients After TKA

PURPOSE: To investigate the improvement in balance after TKA and the difference of balance between posterior cruciate ligament retaining & posterior cruciate ligament substituting prostheses. MATERIALS AND METHODS: Twenty-six patients scheduled to undergo TKA were randomly assigned to receive either PCL-retaining or PCL-substituting prosthesis. The balance of the subjects were checked prior to and at least six months after the operation by computerized dynamic posturography. We investigated whether the balance improve and the difference of change between the implants. RESULTS: Patients showed significantly the improvement of balance by the knee proprioception after TKA (p0.05). CONCLUSION: The balance by the proprioception improves as the HSS Knee Score increases after TKA, and does not show the difference between the implants.
