  • Purpose: The purpose of this study is to assess the results of the autologous osteochondral grafting harvested from medial side of talus for relatively large osteochondral lesion of the medial talar dome. Materials and Methods: From October 2004 to September 2005, 12 patients with osteochondral lesion measured more than 10 mm in axial MRI who were followed up more than 1 year after operation were analyzed. We evaluated postoperative symptoms by Mann and Reynolds scale, morbidity of donor site, and compared the range of both ankle motion. We also evaluated the union at the medial malleolar osteotomy site, trabecular connection between the grafted osteochondral mass and talus, irregularity of the articular surface in lesion. Results: Clinical results were rated as excellent in 4, good in 7, fair in 1. The mean angle of the total range of motion in affected ankle was decreased by 3 degrees compared to that in unaffected ankle. We did not observe abnormal findings at donor site. The osteotomized bone was united at mean 9 weeks (range, 8-12 weeks). We observed trabecular connection between grafted osteochondral mass and talus at mean 14 weeks (range, 12-16 weeks). We also observed irregular articular surface in osteochondral lesions in 6, smooth articular surface in 6. Conclusion: The local autologous osteochondral graft for relatively large osteochondral lesion of the medial talar dome is useful operative method with advantages of wide operative field, low morbidity of donor site, and high satisfaction rate.

  • Background: The aim of this study was to assess the clinical outcomes after treatment of proximal humeral fractures with locking plates, and to determine which factors influence the clinical and radiological outcomes. Methods: Fifty six patients who were treated with locking plates for proximal humeral fractures and had been followed for more than 1 year were enrolled in this study. We performed functional evaluation using the Constant score and analyzed radiographic results. The following factors that may potentially influence the clinical outcomes were assessed: age, gender, type of fracture, presence of medial metaphyseal comminution, bone mineral density, anatomical reduction, restoration of medial mechanical support, and postoperative complications. Results: The mean Constant score was 70.1 points at the final follow-up. Female gender, 4-part fractures, AO type-C fractures, and fractures with medial metaphyseal comminution were associated with a poor clinical outcome. On the other hand, restoration of medial mechanical support and accurate anatomical reduction had a positive influence on clinical outcomes. Postoperative complications resulted in 3 patients (intra-articular screw perforation: 1 patient, varus deformity with screw loosening: 1 patient, nonunion: 1 patient). Conclusions: When treating proximal humeral fractures with locking plate fixation, following factors: a female gender, Neer type 4-part fracture, AO type C fracture, and medial metaphyseal comminution are important risk factors that surgeons should take into consideration. Factors that contribute to better clinical outcomes of operative treatment for humeral fractures are accurate anatomical reduction and restoration of medial mechanical support.

  • Purpose: In surgical treatment of the medial orbital wall fractures, restoring the original position of the orbital wall is difficult in some cases. Under such condition, the orbital wall is often reconstructed with synthetic material, without bony reduction, which is considered to be the conventional reconstruction. The purpose of this study is to compare the outcomes of anatomical reconstruction, which restores the bony wall to the anatomical position, from that of the conventional reduction in the isolated medial orbital wall fractures. Methods: Thirty patients, who underwent reconstruction surgery for the isolated medial orbital wall fractures from March 2007 to August 2011, were reviewed retrospectively. The surgical outcomes of two groups, the conventional reconstruction group (15 patients) and the anatomical reconstruction group (15 patients), were studied in 2 measurements, a one day before and 6 months after the surgery. The changes of orbital volume were calculated by the images from a computed tomography scan and enophthalmos was measured by a Hertel exophthalmometer. Results: The orbital volume ratio was decreased by an average of 1.05% in the conventional reconstruction group, while in the anatomical reconstruction group, the ratio decreased by 5.90% (p<0.05). The changes in the Hertel scale were 0.20 mm in the conventional reconstruction group, and 0.70 mm in the anatomical reconstruction group. However, the difference in the Hertel scale was statistically insignificant (p>0.05). Conclusion: In conclusion, the anatomical reconstruction technique of the isolated medial orbital wall fracture results in a better outcome than that of the conventional reconstruction, in terms of restoring of the original orbital volume and anatomic position. Thus, it can be considered as a useful method for the isolated medial orbital wall fractures.

  • Background: Flat feet can be identified by assessing the collapse of the medial longitudinal arch (MLA) and these conditions can trigger epidemiological changes in the feet. Many of previous studies compared the muscle activity of lower body in terms of intervention and dynamics to treat the structural defect of flat feet. However, few studies have investigated or analyzed the muscle activity of gastrocnemius muscle in the subjects with flat feet. Objects: This study investigated the differences in changes of medial and lateral plantar flexors in subjects with flat feet during bipedal heel-rise (BHR) task and analyzed the differences in muscle activity between two groups by measuring the electromyography (EMG) of abductor hallucis (AH), tibialis anterior (TA), medial gastrocnemius (MG), lateral gastrocnemius (LG). Methods: A total of Twenty one adult females participated in this experiment. Subjects were assigned to groups according to the navicular drop test. The task was applied to the leg, where the heel lifting action prevailed. The muscle activity of the medial and lateral feet plantar flexors was evaluated, and the % maximum voluntary isometric contractions (%MVIC) of these were compared. Results: For the difference between groups the muscle activity (%MVIC) of LG muscle was statistically significantly low in flat feet group compared to healthy feet group (flat feet: 64.57, healthy feet: 90.17; p < 0.05). Conclusion: The results of this study will contribute to identifying the muscle activities of medial and lateral feet plantar flexors among subjects with flat feet, which can cause abnormal epidemiological changes in the feet.

  • Background: The execution of fibular allograft augmentation in unstable proximal humerus fractures (PHFs) was technically demanding. In this study, the authors evaluated the clinical and radiographic outcomes after tricortical iliac allograft (TIA) augmentation in PHFs. Methods: We retrospectively assessed 38 PHF patients treated with locking-plate fixation and TIA augmentation. Insertion of a TIA was indicated when an unstable PHF showed a large cavitary defect and poor medial column support after open reduction, regardless of the presence of medial cortical comminution in preoperative images. Radiographic imaging parameters (humeral head height, HHH; humeral neck-shaft angle, HNSA; head mediolateral offset, HMLO; and status of the union), Constant score, and range of motion were evaluated. Patients were grouped according to whether the medial column support after open reduction was poor or not (groups A and B, respectively); clinical outcomes were compared for all parameters. Results: All fractures healed radiologically (average duration to complete union, 5.8 months). At final evaluation, the average Constant score was 73 points and the mean active forward flexion was $148^{\circ}$. Based on the Paavolainen assessment method, 33 patients had good results and 5 patients showed fair results. The mean loss of reduction was 1.32 mm in HHH and 5.02% in HMLO. None of the parameters evaluated showed a statistically significant difference between the two groups (poor and not poor medial column support). Conclusions: In unstable PHFs, TIA augmentation can provide good clinical and radiological results when there are poor medial column support and a large cavitary defect after open reduction.

  • Background: In this study, the abductor hallucis activity and medial longitudinal arch angle were compared by performing four exercises, namely the short foot exercise, the short foot exercise with 2nd~5th toe extension, the short foot exercise with 2nd~5th toe extension with a load of 1kt on the sole, and the short foot exercise with 2nd~5th toe extension with a load of 2kg on the sole. Methods: Four short foot exercises as described above were performed by 20 healthy adult males and females. The abductor hallucis activity and medial longitudinal arch angle were measured and analyzed by surface electromyography and the Kinovea software program. Results: The short foot exercise with 2nd~5th toe extension, short foot exercise with 2nd~5th toe extension with a load of 1kg on the sole, and the short foot exercise with 2nd~5th toe extension with a load of 2kg on the sole showed significantly higher abductor hallucis activity than the short foot exercise alone. Among these, the short foot exercise with the 2nd~5th toe extension was the most effective. All exercises showed a significantly decreased medial longitudinal arch angle post-exercise than pre-exercise, and the short foot exercise with the 2nd~5th toe extension showed a significantly decreased medial longitudinal arch angle compared to the other three exercises. Conclusion: It is believed that the short foot exercise with the 2nd~5th toe extension can be proposed as an effective exercise that can replace the short foot exercise alone.

  • Background: The medial canthal region features a complex three-dimensional and internal anatomical structure. When reconstructing a defect in this area, it is crucial to consider both functional and aesthetic aspects, which presents significant challenges. Generally, local flaps are preferred for reconstruction; however, skin grafts can be used when local flaps are not feasible. Therefore, we conducted a comparative analysis of surgical outcomes skin grafts when local flaps were not feasible, to determine which surgical method is more effective for medial canthal region reconstruction. Methods: Twenty-five patients who underwent medial canthal region reconstruction using skin grafts or local flaps from 2002 to 2021 were enrolled. Patient information was obtained from medical records. Five plastic surgeons evaluated the surgical outcomes based on general appearance, color, contour, and symmetry. Results: Skin grafts were used in eight patients and local flaps were used in 13. Combined reconstructions were employed in four cases. Minor complications arose in four cases but improved with conservative treatment. No major complications were reported. Recurrence of the skin cancer was noted in two cases. All categories showed higher scores for the local flap compared to both skin graft and combined reconstruction; however, the differences were not statistically significant respectively. Conclusion: The choice of appropriate surgical methods for reconstructing defects in the medial canthal region depends on various factors, including the patient's overall health, the size and depth of the defect, and the degree of involvement of surrounding structures. When a local flap is not feasible, a skin graft may provide favorable surgical outcomes. Therefore, a skin graft can serve as a viable alternative for reconstructing the medial canthal region.

  • Purpose: Blowout fracture is an outward fracture of the orbital wall. That usually occurs at inferior or medial wall of the orbit. The main pathophysiology is high intraocular pressure derived from impact of trauma. Among the four orbital wall, the medial wall is thinnest and most vulnerable to trauma. Many kinds of methods were introduced for correction of medial orbital wall fracture. Recently, transnasal endoscopic reconstruction methods were widely used. Endoscopic methods had many advantages. However, we experienced some cases of postoperative maxillary sinusitis. This study was planned to find out the effectiveness of middle meatal antrostomy after endoscopic reconstruction of medial orbital wall fracture. Methods: This study was retrospective analysis of 28 patients who underwent transnasal endoscopic repair of medial orbital wall fracture. The 18 male and 10 female patients were ranged from 17 to 57 years of age(mean, 30.9 years). Among 28 patients, randomly selected 17 patients underwent middle meatal antrostomy as additional procedure by the same surgeon. After at least 12 months of follow-up period, we examined the nasal symptom, endoscopic and CT findings. Results: One patient complained of nasal obstruction in middle meatal antrostomy group and four patients complained nasal symptoms in non middle meatal antrostomy group. On the endoscopic findings, three patients of non middle meatal antrostomy group had continuous nasal discharge. But middle meatal antrostomy group had no abnormal endoscopic findings. The abnormal CT finding(abnormal mucosal hypertrophy) were detected in four patient of non middle meatal antrostomy group. There were no abnormal CT findings in middle meatal antrostomy group. The data were statistically significant at comparative study. Conclusion: Authors think that the middle meatal antrostomy has some advantages as a additional procedure of endoscopic reconstruction of medial orbital wall fracture. Especially, it is good at preventing postoperative maxillary sinusitis. But, more larger group and strict application of disease entity are need for correct evaluation of middle meatal antrostomy effect.

  • Purpose: This study intends to verify the usefulness of magnetic resonance imaging (MRI) for estimate recovery after arthroscopic pull-out repair at root tears of medial meniscus. Materials and Methods: We performed 17 patients who examined MRI and arthroscopy among patients who had received repair of medial meniscus from November, 2007 to June, 2011. To determine restoration meniscus, we performed arthroscopy and MRI. Results: Lysholm knee scores before and after operation were average 56.4 and 79.0 and visual analogue scale (VAS) score was improved from 8 points to 3 points. From secondary look arthroscopy performed after operation, 17 cases showed stabilization after regeneration. However, In MRI, cleft sign implying root tears of medial meniscus was observed in all cases before and after operation, ghost sign was observed in 10 cases and 9 cases respectively, radial linear defect was showed 17 cases and 15 cases respectively. Conclusion: It was not useful that MRI after medial meniscus repair in non-anatomical site, to consider restoration of medial meniscus. To evaluate for recovery medial meniscus after repair more exactly, secondary arthroscopy would be required.
