Ultrasonographic Usefulness for Diagnosis of Acetabular Labral Tear / 대한고관절학회지

PURPOSE: This study evaluated the usefulness of ultrasonography for a diagnosis of acetabular labral tear in femoroacetabular impingement (FAI). MATERIALS AND METHODS: From March 2010 to October 2011, an ultrasonographic examination was performed in 58 patients(58 hips: 26 men and 32 women) with acetabular labral tear. The sensitivity and positive predictive value of ultrasonography were evaluated for 58 cases with acetabular labral tear confirmed by hip arthroscopy. RESULTS: The sensitivity and positive predictive value for an acetabular labral tear using ultrasonography was 89.6% and 100%, respectively. The concordance rate of an acetabular labral tear between arthroscopy and ultrasonography was 84.6%. CONCLUSION: Hip ultrasonography can make a significant contribution to a pathologic diagnosis and isa useful diagnostic tool for acetabular labral tears.

Relationship between Union of Grafted Autologous Bone and Clinical Results of Operative Treatment of Degenerative Spondylolisthesis by Posterolateral Fusion / 대한정형외과학회잡지

PURPOSE: Bone graft is essential for successful spinal fusion. So, we clinically assessed the effect of uniting grafted autologous bone. MATERIALS AND METHODS: Retrospective analysis is performed on 46 patients who had grade I or II, one segmental, degenerative spondyloiisthesis according to Meyerding classification and treated operatively by posterolateral fusion with posterior decompression and autologous iliac bone graft from January 1991 to June 1996. We got the data from simple anteroposterior, lateral, flexion- extension X-ray film at preoperative, postoperative and last follow-up period, and from clinical results at last OPD follow-up according to Kirkaldy-Willis criteria. We compared the union of grafted autologous bone with clinical results using X2-test. We also compared preoperative spinal instability, with/without instrumentation and intraoperative reduction with the union of grafted autologous bane and clinical results. RESULTS: There was high significant correlation (P=0.000) between the union of grafted autologous bone and clinical results statistically, CONCLUSIONS: This results suggest that the union of grafted autologous bone was an important factor in determing clinical results.

Classification and Treatment of SLAP Lesion / 대한정형외과학회잡지

PURPOSE: The Snyder's classification of SLAP lesion has many limitations in clinical use, His classification has no correlation with the mechanism of jnjury and treatment. Therefore, new rational classification oriented with injury mechanism and its treatment was needed. MATERIALS AND METHODS: This is a retrospective study of 74 patients with SLAP lesion which were found during arthroscopic treatment of 194 patients diagnosed with recurrent shoulder dislocation, impingement syndrome or SLAP lesion between March 1989 and January 1997. Mean follow-up time was 36 months (range, 18 to 72 months) and average age of patients was 26 years old (range, 17-47 yrs). All patients were arthroscopically examined and treated. We classified the SLAP lesion into 3 groups according to the stability of biceps anchor. Group I had superior labral tear (flap tear or bucket-handle tear or degenerative tear) with intact biceps stability, group II had disturbed biceps anchor (unstable shoulder), and group III is a mix of group I and II. By our classification, group I was 32 cases, group II was 31 cases, and group III was 11 cases. We treated the SLAP lesion according to our new classification. Group I was treated with arthroscopic debridement, group II with stabilization of biceps anchor, and group III with arthroscopic debridement and stabilization of biceps anchor. RESULTS: The result by the Rowe rating scale was excellent or good in 29 cases of 32 in group I, 25 cases of 29 in arthroscopic transglenoid suture technique group and 1 case of 2 in the group treated with biodegradable tack (Suretec) in group II, and 10 of 11 cases in group III. There was only one case of postoperative recurrence and no complication was found. Our transglenoid suture technique had a reasonable recurrence rate with few complications. CONCLUSIONS: Thus we propose our new classification and treatment of SLAP lesion, and arthroscopic transglenoid suture technique for the treatment of SLAP type II and III.
