Purpose: To compare the efficacy between cast immobilization and functional treatment using an ankle brace as a treatment for acute lateral ankle sprain. Materials and Methods: This study reviewed the medical records of 157 acute ankle sprain patients who were treated between 2009 and 2014. A total of 101 cases were included in this study except for cases with a combined injury, and could not be followed up for eight weeks after the first visit. The patients were divided according to the treatment modality: a cast immobilization group (64 cases) and functional treatment group (37 cases). The clinical outcomes were assessed retrospectively based on the medical records of each group. The residual symptoms, such as pain, swelling, and instability, at three weeks after the primary treatment and at the last visit were compared. Results: The residual pain and instability were significantly common in the functional treatment group at three weeks. Five cases (7.8%) of pain and one case (1.6%) of instability were in the cast group whereas nine cases (24.3%) of pain and six cases (16.2%) of instability in functional treatment group (p=0.021, p=0.014). On the other hand, there was no meaningful difference at the last follow-up. Residual pain, swelling, and instability at the last visit were noted in three (4.7%), six (9.4%), and four cases (6.3%) in the cast group, and three (8.1%), three (8.1%), and three (8.1%) were observed in the functional treatment group. Six patients refused cast immobilization. Conclusion: Although there was no significant difference at the last follow-up, cast immobilization appears to be more effective than a functional brace in terms of early pain relief and early restoration of ankle stability as a treatment for acute ankle lateral sprain in this study

Purpose: To evaluate the correlation between the fibrillar pattern of the Achilles tendon on ultrasonography (US) and functional outcomes in patients who underwent open tendon repair after Achilles tendon rupture. Materials and Methods: Data of 44 patients who had been subjected to US at least 6 months after repair, during the period between July 2012 and July 2019 were reviewed. Those with bilateral tendon rupture, re-rupture, open injury, and chronic or insertional rupture, were excluded from the review. We divided them into two groups, the homogenous group (HoP) and the heterogenous group (HeP) based on the fibrillar pattern on US. We also divided the HoP into linear and wavy subgroups, and the HeP into no hypoechoic lesion and hypoechoic lesion subgroups. The rupture type of the Achilles tendon, radiographic factors including US and magnetic resonance images, patient-related, surgical factors, and clinical results at the last visit after repair were assessed retrospectively. Results: The tendon thickness was 11.4±1.7 mm in the HoP, and 14.5±3.0 mm in the HeP (p<0.001). A shredded pattern was observed in 17 cases (65.4%) in the HoP, and in 17 cases (94.4%) in the HeP (p=0.031). The mean value of the number of sutures used was 8.9±3.05 in the HoP and 11.39±1.75 in the HeP (p=0.001). The mean value of the difference in calf circumference was 0.9±0.67 cm in the HoP and 1.36±0.71 cm in the HeP (p=0.037). There were no statistically significant differences in the fibrillar patterns and patient-related factors. Conclusion: The fibrillar pattern observed after repair was correlated with the functional outcome and showed a significant relationship with the rupture pattern and the number of sutures used. Therefore, we suggest a careful individualized postoperative rehabilitation protocol to maximize functional outcomes by referring to the fibrillar pattern in US, especially in shredded ruptures.

Purpose: We compared plain radiographs with computed tomography (CT) images to evaluate the usefulness of preoperative CT in acute ankle malleolar fracture in terms of accuracy of diagnosis and planning of operative strategy. Materials and Methods: A retrospective analysis was conducted on 210 cases of malleolar fracture treated at our institute for which plain radiograph and CT were obtained preoperatively. Observers had reviewed plain radiographs and recorded fracture classification, anatomical diagnosis, extent and configuration of fractures and then subsequently reviewed CT images. Records from each image were compared and information regarding the differences in fractures was assessed. Results: Fractures were notably changed in appearance in 88 cases (41.9%) and diagnosis changed in 30 cases (14.3%). According to the change of diagnosis and fracture appearances, the operative strategy was changed in 15 cases (7.1%) including incision, order of reduction, and target of fixation. Conclusion: CT could be a useful adjunctive imaging tool in addition to the plain radiograph in planning of operative treatment for acute malleolar fracture in terms of estimating exact configuration, extent of fractures and even newly revealed hidden fractures.

Study Design: A retrospective study. Purpose: To determine the exact distal fusion level in the management of thoracolumbar/lumbar adolescent idiopathic scoliosis (TL/L AIS) using pedicle screw instrumentation (PSI). Overview of Literature: The selection of distal fusion level remains controversial in TL/L AIS. Methods: Radiographic parameters of 66 TL/L AIS patients were analyzed. The patients were grouped according to the distal fusion level; L3 group (fusion to L3, n=58) and L4 group (fusion to L4, n=8). The L3 group was subdivided into L3A (L3 crosses the mid-sacral line with rotation of less than grade II, n=33) and L3B (L3 does not cross the mid-sacral line or rotation is grade II or more, n=25) based on both bending radiographs. All of the patients in the L4 group had the same location and rotation of L3 in bending films as that of patients in the L3B group. An unsatisfactory result was defined as a lowest instrumented vertebral tilt (LIVT) of more than 10° or coronal balance of more than 15 mm. Results: Among the 3 groups, there was a significantly lesser correction in the TL/L curve and LIVT in the L3B group. Unsatisfactory results were obtained in 3 patients (9.1%) of the L3A group, in 15 patients (68.2%) of the L3B group, and in 1 patient (12.5%) of the L4 group with a significant difference. Conclusions: In TL/L AIS treatment with PSI, the curve can be fused to L3 with favorable radiographic outcomes when L3 crosses the mid-sacral line with rotation of less than grade II in bending films. Otherwise, fusion has to be extended to L4.
