We designed this study to evaluate the functional outcome and to suggest the guidelines in the treatment of bimalleolar ankle fractures with clinical and radiological analysis after operative treatment. We analyzed 36 patients with bimalleolar fractures among 90 ankle fractures and followed up for more than 1 year. All 36 fractures were classified according to Lauge-Hansen system and the Meyer criteria was used for the clinical and radiological assessment. Seventeen cases(47%) were supination-external rotation(47%); 9 cases(25%) were supination-adduction; 6 cases(17%) were pronation-abduction and 4 cases(11 %) were pronation-external rotation type. Satisfactory results was obtained in 32 cases(89%) according to the criteria of Meyer in the viewpoint of clinical and radiological analysis. Satisfactory results could be obtained with early anatomical reduction and rigid internal fixation for the treatment of bimalleolar ankle fractures. Distal tibiofibular syndesmosis disruption could be spontaneously reduced without trans-syndesmotic screw fixation by early open reduction and rigid internal fixation for the bimalleolar ankle fractures. Early and more accurate anatomical reduction can reduce the post-traumatic arthritis in cases with moderate talar displacement and open fractures.

Tenosynovial Giant Cell Tumor Arising from Femoral Attachment of the Anterior Cruciate Ligament

이주홍,왕성일 대한정형외과학회 2014 Clinics in Orthopedic Surgery Vol.6 No.2

The localized type of tenosynovial giant cell tumor usually occurs on the palmar side of fingers and toes. Tenosynovial giant cell tumors of the tendon sheath are rarely intra-articular. We report a giant cell tumor of the tendon sheath arising from femoral attachment of the anterior cruciate ligament and its treatment with arthroscopy in a 28-year-old man

Risk of Anterior Femoral Notching in Navigated Total Knee Arthroplasty

이주홍,왕성일 대한정형외과학회 2015 Clinics in Orthopedic Surgery Vol.7 No.2

We retrospectively investigated the prevalence of femoral anterior notching and risk factors after total knee arthroplasty (TKA) using an image-free navigation system. Methods: We retrospectively reviewed 148 consecutive TKAs in 130 patients beginning in July 2005. Seventy knees (62 patients) underwent conventional TKA, and 78 knees (68 patients) received navigated TKA. We investigated the prevalence of femoral anterior notching and measured notching depth by conventional and navigated TKA. Additionally, the navigated TKA group was categorized into two subgroups according to whether anterior femoral notching had occurred. The degree of preoperative varus deformity, femoral bowing, and mediolateral suitability of the size of the femoral component were determined by reviewing preoperative and postoperative radiographs. The resection angle on the sagittal plane and the angle of external rotation that was set by the navigation system were checked when resecting the distal femur. Clinical outcomes were compared using range of motion (ROM) and the Hospital for Special Surgery (HSS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAX) scores between the two groups. Results: The prevalence of anterior femoral notching by conventional TKA was 5.7%, and that for navigated TKA was 16.7% (p = 0.037). Mean notching depth by conventional TKA was 2.92 ± 1.18 mm (range, 1.8 to 4.5 mm) and 3.32 ± 1.54 mm (range, 1.55 to 6.93 mm) by navigated TKA. Preoperative anterior femoral bowing was observed in 61.5% (p = 0.047) and both anterior and lateral femoral bowing in five cases in notching group during navigated TKA (p = 0.021). Oversized femoral components were inserted in 53.8% of cases (p = 0.035). No differences in clinical outcomes for ROM or the HSS and WOMAX scores were observed between the groups. A periprosthetic fracture, which was considered a notching-related side effect, occurred in one case each in the conventional and navigated TKA groups. Conclusions: Surgeons should be aware of the risks associated with anterior femoral notching when using a navigation system for TKA. A modification of the femoral cut should be considered when remarkable femoral bowing is observed.

압축영상의 화질향상을 위한 블록킹 현상 제거에 관한 연구

이주홍,김민구,정제창,최병욱 한국통신학회 1997 韓國通信學會論文誌 Vol.22 No.8

블록 변환 부호화는 가장 널리 사용되고 있는 영상 압축의 한 방법이다. 한 예로 이산 여현 부호화는 MPEG-1, MPEG-2, JPEG, H.261과 같은 국제 표준에서 널리 사용되고 있다. 이러한 블록 단위의 변환 부호화에서, 특히 압축률이 높은 응용 분양에서는 그 변환 계수들의 양자화 에러가 커져 블록의 경계면을 따라 소위 블로킹 현상이 발생하여 화질 열화의 원인이 되고 있다. 본 논문에서는 고능률 변환 부호화 영상 압축에 있어서의 새로운 블록킹 현상 제거 기법을 제안한다. 블록킹 현상을 제거하기 위해, 수신측에서 복원된 영상에 블록단위로 적절한 보상항을 더하여 경계면의 불연속성을 감소시키고자 한다. 이때의 보상항은 경계면에서 직교인 28개의 기저영상의 선형 결합으로 이루어지는데, 이 28개의 경계 직교 기저 영상들을 구하기 위해, 블록 경계면 화소값들이 각각 선형 독립인 28개의 DCT 커널 함수들에 Gram-Schmidt 방법을 적용한다. 또한 제안된 방법을 적용할 때 윤곽선이 흐려지는 것을 방지하기 위해 블록 불연속 임계치를 정의하여 적응적으로 제안된 방식을 적용한다. 또, 압축률의 변화에 따른 블록킹 현상의 효과적 제거를 위해 필요한 기저 영상의 개수를 고찰한다. Block-transform coding is one of the most popular approaches for image compression. For example, DCT is widely used in the internaltional standards standards such as MPEG-1, MPEG-2, JPEG, and H.261. In the block-based transform coding, blocking artifacts may appear along block boundaries, and they can cause severe image degradation eqpecially when the transform coefficients are coarsely quantized. In this paper, we propose a new method for blocking artifacts reduction in transform-coded images. For blocking artifacts reduction, we add a correction term, on a block basis, composed of a linear combination of 28 basis images that are orthonormal on block boundaries. We select 28 DCT kernel functions of which boundary values are linearly independent, and Gram-Schmidt process is applied to the boundary values in order to obtain 28 boundary-orthonormal basis images. A threshold of bolock discontinuity is introduced for improvement of visual quality by reducing image blurring. We also investigate the number of basis images needed for efficient blocking artifacts reduction when the compression ratio changes.

Purpose: to appreciate the effectiveness of the closed reduction and percutaneous pinning(CRPP) in reducible but unstable displaced surgical neck fracture of the humerus. Materials and Methods: reviewed 30 patients(19 cases in CRPP and l 1 cases in ORIF) with at least 1 year follow-up, comparing clinical union time, elapsed time for surgery and clinical results using UCLA end-result scoring system in two groups and determining prognostic factors in CRPP. Results: Clinical union was seen 8.4 weeks in CRPP and 11.2 weeks in ORIF. The difference between two groups in the clinical results was not significant. Lower UCLA score in CRPP correlated with the increment in age(p$lt;0.05), but not with sex and metaphyseal comminution. Elapsed time for surgery was taken average 38 minutes in CRPP and average 95 minutes in ORIF. The postoperative complications in CRPP were 1 in nonunion, 4 in stiffness and 4 in pin loosening, most of them were occurred in female over sixty. Summary: CRPP is a useful alternative and may be primarily applicable method in respect of comparable results to ORIF, minimal soft tissue damage and shorter surgical time. However, in cases of female with sixty or more, ORIF would be preferred because of poor bone quality, less compliant, and frequent joint stiffness.
