Twenty adult humeri and 14 cadaveric shoulders were included in this study. After placing the precontoured plate in the well-fitted position on the humerus, we measured the distance between the upper margin of the plate and the tip of greater tuberosity (GT) (distance A) and the distance between the anterior margin of the plate and lateral border of the bicipital groove (BG) (distance B). The prevalence of K-wire exits was assessed. In the 14 cadaver shoulders, the mutual relation between the most inferior locking sleeve of the optimally positioned plate and the axillary nerve was evaluated to assess the potential for axillary nerve injury. The precontoured plate was well-fitted and remained in a relatively constant position in al...

Thirty adult cadavers (15 males and 15 females) without ankle problems were enrolled and subjected to continuous 0.75 mm-slice computed tomography (CT) scans. CT images were imported into Mimics software to reconstruct three-dimensional (3D) model of ankle. Using free 360° rotations with magnification, the 3D mutual relationships of ankle syndesmosis were assessed, and the fibular congruency of incisura was evaluated to determine the optimal screw trajectory. By reformatting the CT scanning plane along the screw direction, the coronal relation of ankle syndesmosis was evaluated to verify the distance between the adjacent bones. The fibula was placed in the concentric position of fibular incisura in the 20 models (concentric group) and 40 models, in an eccentric position (eccentric group). Despite th...

We aimed to make IS screw trajectory with fully intraosseous path that was optimal and consistent, and confirm the possibility of transiliac-transsacral (TITS) screw fixation in Asian sacrum. Eighty-two cadaveric sacra (42 males and 40 females) were enrolled and underwent continuous 1.0-mm slice computed tomography (CT) scans. CT images were imported into Mimics® software to reconstruct three-dimensional model of the pelvis. To simulate IS screws, we inserted 7.0-mm-sized TITS cylinder for first (S1) and second (S2) sacral segment and 7.0-mm oblique cylinder for S1. TITS cylinder could not be inserted into S1 of 14 models (sacral variation models) but could be inserted into the S2 of all models. The actual length of virtual IS screws was measured, and anatomic features of safe zone (SZS2) including the area, horizon...

Materials and Methods: 59 consecutive cases of rotator cuff tearing which were treated with mini-open repair utilizing the anterolateral approach were evaluated. The population comprised 39 men and 20 women, with an average age of 56.6 years. An average follow-up time period was 26 months. Clinical outcomes were analyzed based on VAS, ADL, and ASES scores. Results: The average respective VAS, ADL, and ASES scores improved from 7.04, 12.37, and 35.32 preoperatively to 1.02, 27.20, and 90.08 postoperatively (p=0.000). There were 41 excellent, 11 good, 2 fair, and 5 poor results. There were satisfactory results in 52 cases (88.1%). There were no statistically significant differences between the final ASES scores and age, sex, duration of symptoms, tear size, and preoperative stiffness (p>0.05).

Furthermore, most of these combined acromial fractures have minimal displacement, which needs no additional treatment other than protection for a certain period of time. We have experienced a case of isolated fracture of the posterolateral angle of the acromion, which we reduced and fixated using K-wire and cannulated screws. We report on the technical aspects and clinical results of this reduction and fixation, along with a review of the literature.

Materials and Methods: Two fractures of the coronoid process that needed to be fixed were managed with open reduction and internal fixation through a medial approach using 2.4 mm locking compression plates (Compact Hand set � , Synthes, Switzerland). The patients were followed up for 14 months and 17 months and were evaluated using the Mayo Elbow Performance Score (MEPS). Results: The MEPS was 95 for Case 1 and 100 for Case 2. Active elbow joint motions were 5。 -120。 (Case 1) and 0。 -130。(Case 2). Supination and pronation fully recovered. Conclusion: Satisfactory results can be obtained in cases of coronoid process fractures because volar plating through a medial approach allows sound fixation and early mobilization of the elbow joint.

We analyzed the functional results by the Korean shoulder score, the Constant-Murley score and the reduction state of the acromioclavicular joint at the last follow-up. Results: All the cases achieved a satisfactory outcome. The mean Korean shoulder score was 89.9 (range: 81-100) points and the mean Constant-Murley score was 87.8 (range: 82-93) points. According to the radiologic findings, 8 patients achieved anatomical reduction of the acromioclavicular joint: there was a slight loss of reduction in one patient and a partial loss of reduction in one patient. None of the patients had deep infection or re-dislocation. Conclusion: The operative treatment using two suture anchors and Kirschner wire may be used for acute Rockwood type V acromioclavicular joint dislocation, and it has an advantage in that it can prevent chondral injury of the joint.

The purpose of this study was to establish the safe zone for the antegrade posterior lag screw by using computational analysis. The virtual three-dimensional model of 178 hemi-pelvises was created from the CT data (DICOM format) by using Mimics(®) program, and were used to measure the safe zone of antegrade lag screw fixation on the inner table of the iliac wing, and the largest diameter of cylindrical implant inside safe zone.

Materials and Methods: From May 2006 to August 2013, 48 fractures were enrolled in fast-track, and were an average age of patients was 77.6 years (range, 62-97 years). They underwent primary testing for anesthesia, including basic body fluid test, arterial blood, electrocardiography, and chest radiographs. The time from visit to surgery was 28.9 hours (range, 1-96 hours). Results: During hospitalization, there was one case of stress-induced cardiac arrest; however, other complications, infection, and 30-day mortality did not occur. According to preoperative classic test, the average albumin was 3.45 g/dl, blood sugar, 169 mg/dl, blood urea nitrogen, 20.5 mg/dl, Cr, 1.5 mg/dl, Na, 135.3 mEq/L, and K, 4.21 mEq/L. The average PaCO2 of arterial blood was 37.6 mmHg. Conclusion: We found that the fast-track for trochanteric fracture due to slip-down was relatively safe, and could be considered as a therapeutic approach.

Indirect reduction with the use of the femoral distractor is a much more efficient technique to restore the length in the fracture of lower limbs. However, the femoral distractor cannot be used for fracture of upper limbs, and other instruments for indirect reduction have not yet been reported. Therefore, we introduce the novel indirect reduction technique with the use of the lumbar spreader for the MIPO of upper limbs.
