Purpose: Problematic late sequelae are common following a calcaneal fracture regardless of the initial treatment. We retrospectively evaluated the painful conditions and reviewed the results of the operative treatment in patients with previously treated calcaneal fractures. Materials and Methods: Between October 1996 and September 2001, forty-three patients who underwent subsequent surgical treatment for late sequelae of calcaneal fracture were reviewed. The initial treatment consisted of only immobilization in a cast in 7 patients, closed reduction with pin fixation (Essex-Lopresti technique) in 22 and open reduction and internal fixation in 14. Painful conditions in the hind foot included subtalar arthritis in 31 patients, calcaneofibular impingement in 13, peroneal tendinitis in 6, displaced posterior bony fragment in 3, sural neuritis in 2, subtalar and midtarsal arthritis in 1 and displaced plantar bony fragment in 1. The surgical procedures for the late complications were performed at a mean of 19 months (range, 6 to 35 months) after the injury and consisted of lateral wall ostectomy and in situ subtalar fusion in 28 patients, only lateral wall ostectomy in 5 patients, lateral wall ostectomy and subtalar distraction arthrodesis in 3, removal of displaced posterior bony fragment in 3, sural nerve transposition in the peroneus brevis in 2, triple arthrodesis in 1 and removal of displaced plantar bony fragment in 1. Mean postoperative follow up period was 57 months (range, 33 to 82 months). The results of treatment were evaluated on the basis of pain, improvement in the ability to perform activities of daily living, to return to work or to a pre-injury level of activity. Results: Pain was partially relieved in 38 patients (88%), but not relieved in 5. Function improved in 34 patients (79%), and 32 (74%) returned to work or to a pre-injury level of activity. There was a trend that the longer the interval between the injury and the operation, the longer the subsequent interval until the patient returned to full activities or work. Conclusion: Meticulous physical examination and intensive prompt treatment for remaining pain after initial treatment of calcaneal fractures are recommended for patient's satisfaction and returning to work.

Purpose: This study was aimed at elucidating the pathogenesis of talar osteochondral lesion by analyzing the histopathological findings. Materials and Methods: Twenty specimens from 20 patients who underwent surgical treatment for talus osteochondral lesions were studied. Preoperative MRI images including T1, T2, and stir images were taken and cases were classified according to modification of the Anderson's classification. There were 5 cases of MRI group 1, 6 cases of group 2, 7 cases of group 3 and 2 cases of group 4. A full thickness osteochondral plug including the osteochondral lesion of the talus was harvested from each patient and reviewed histopathologic changes of osteochondral fragment using H-E staining. Mean diameter of specimens was 8.5 mm and mean depth was 10.3 mm. Pathologic changes of articular cartilage and subchondral bone were observed. Subchondral bone was divided into superficial, middle and deep zones according to depth. Cartilage formation, trabecular thickening and marrow fibrosis were observed in each zone. Results: There were detachment of the joint cartilage at the tidemark in 16 cases of 20 cases and the separated cartilages were almost necrotic on the histopathologic findings. Cartilage formation within subchondral bone was discovered beneath the tidemark in 12 cases. Trabeculae were increased and thickened in 17 cases. These pathologic changes were similar to fracture healing process and these findings were more conspicuous near the tidemark and showed transition to normal bone marrow tissue with depth. No correlation between the pathological progression and MRI stages was found. A large cyst shown on MRI's was microscopically turned out to be multiple micro-cysts accompanied by fibrovascular structure and newly formed cartilage tissue. Conclusion: The histopathologic findings of osteochondral lesions are detachment of overlying cartilage at the tidemark and subsequent changes of subchondral bone. Subchondral bone changes are summarized as cartilage formation, marrow fibrosis and trabecular thickening that mean healing process following repeated micro fractures of trabecular. These osteochondral lesions should have differed from osteochondral fractures.

Purpose: To report the clinical result of the intraarticular calcaneus fracture after open reduction and internal fixation with plate by lateral approach. Materials and Methods: Thirty-six calcaneal fractures of 33 patients(29 men and 4 women) were treated by open reduction and internal fixation using an lateral approach from March, 1997 to May, 2002 and were followed more than one year. The autogenous iliac bone graft was done in 2 cases but the others didn't. Radiographically B?hler angle and Gissane angle on simple lateral radiograph were measured and in the 15 cases, the step-off(gap) of posterior facet joint on post-operative CT images were followed. The Salama method was used for evaluation of clinical results. Results: According to Sanders classification, 19 cases of the 36 cases were classified as type II. Type III fracture were found in 12 cases and type IV in 5 cases. The following results were obtained: twenty-two cases(61.1%) out of 36 cases were estimated as good or excellent. The good results or more were obtained in 15 cases(78.9%) in type II and 7 cases(58.3%) in type ill, but no case in type IV. B?hler angles were improved from preoperative average 1.6?to postoperative average 23.4?, Gissane angle was improved from preoperative 107.2?to postoperative 122.8?, respectively. Among 36 cases, Computed tomography was carried out in 15 cases. The postoperative step-off (gap) of posterior facet joint on computed tomography was filled with cancellous bone. Satifactory results was obtained in 7 cases with 2mm gap or less and in 6 cases of 2-5mm. There were no satifactory results in 2 cases with 5mm gap or more. Conclusion: Open reduction and internal fixation for intra-articular fracture of calcaneus was thought to be a good treatment modality. It is thought that the lateral approach is one of the good one for surgical treatment, and that accurate reduction of the posterior facet, acceptable recovery of B?hler angle are more important to obtain best results.

Objective : The purpose of this study is to investigate the characteristics of patients with fracture admitted in oriental hospital. Methods : From october 1996 to october 2001, we retrospectively evaluated the simple radiographic proven 8441 patients with musculoskeletal pain in oriental hospital. The patients included 3899 men and 4542 women. All fractures were analyzed in terms of location, age and sex. Results : 1. The fracture rate of radiologic study was relatively high in foot, chest, upper extremity and hand. The frequent fractures were in spine (257 cases), foot (119 cases), upper extremity (83 cases). and chest (68 cases). 2. The male patients with fracture were significantly higher than female in 0-40 years group: in 0-20 years group(8.5 % vs 4.0 %, p<0.01), in 21-40 years group (4.1 % vs 2.6, p<0.05), while female patients with fracture were significantly higher than male patients in more than 60 years group( 10.1 % vs 15.4 %, p<0.01). 3. The incidence of fracture showed significant association with increased age except 0-20 years group(p<0.01). Spine and chest cage in mate, and upper extremity, pelvis, spine, ankle and chest cage in female were significantly higher on older age groups. Conclusion : The overall fracture rate of radiologic study was 6.6 % for patients with musculoskeletal problem admitted in oriental hospital. The distribution of fracture showed significant difference in terms of age, sex and site. So we believe the radiologic study is helpful to evaluate fracture in oriental hospital.

Eleven patients with calcaneal fracture had 2 acute compartment syndrome of the feet and 9 late complication of the compartment syndrome of the feet. An interstitial pressure of more than 30 mmHg in either the central or interosseous compartment was considered pathologic and was treated by fasciotomy performed medially. Rigid claw toe deformity was treated by excision of the head and neck of the proximal phalanx, dorsal capsular release of the metatarsophalangeal joint, and lengthening of the extensor tendon. Patients were evaluated at a mean of 35 months(range, 21 - 44 months) after operation, and the examination was directed specifically toward symptoms and signs of myoneural ischemia, and walking pain. At follow-up, 2 patients with acute compartment syndrome of the foot had no evidence of myoneural ischemia, 9 patients with claw toe deformity had no pain with walking. Based on our clinical observations, we concluded that compartment syndrome of the foot may occur after the calcaneal fracture and fasciotomy is effective treatment for the prevention of the long term sequelae of this debilitating condition.

Purpose: To statistically evaluate the contributing role of the 3 radiographic factors (Obliquity, Asymmetry, Joint deviation) of the hallux valgus interphalangeus with comparison to the normal control group. Materials and Methods: The study is based on the standing foot AP radiographs of the 77 feet (56 patients) of the hallux valgus interphalangeus out of 119 feet of randomly sampled patients of the age range 20 to 60. Fractures or other foot disorders have been excluded. Obliquity, asymmetry and joint deviation factors formed by proximal and distal phalanges of hallux are measured by one observer and evaluated the statistical significance of the contribution of the 3 factors to the hallux interphalangeal angle (HIA). Results: The average age of the patients were 36.0 years old and average HIA was $14.5^{\circ}{\pm}2.8^{\circ}$. Obliquity was measured $4.8^{\circ}{\pm}2.90^{\circ}$, asymmetry $8.2^{\circ}{\pm}3.28^{\circ}$ and joint deviation $2.0^{\circ}{\pm}1.85^{\circ}$. All 3 factors showed the statistical significance as the contributing factors to the HIA and among them, the asymmetry played the biggest role (p<0.05). Conclusion: Hallux interphalangeal angle is formed by 3 radiographic factors (Obliquity, Asymmetry, Joint deviation), and among them the asymmetry factor plays the biggest role.

The triplane fracture has been described as a fracture of the distal tibial epiphysis occurring across three planes-sagittal, transverse and coronal. The characteristic pattern of fusion of distal tibial epiphysis explains the special configuration of the fragments in the triplane fracture. According to Dias-Tachdjian classification, triplane fracture is classified two part fracture, three part fracture, four part fracture and two part fracture with extension to the medial malleolus. Among four types, two part triplane fracture with extension to the medial malleolus is a relatively rare injury and generally is not treated by closed reduction. Such fractures should have an anatomic reduction and adequate fixation to restore the joint congruity and obtain an anatomic reduction of the growth plate to prevent a future growth deformity. This is usually best accomplished with an open reduction and screw fixation or k-wire fixation. We experienced two part triplane fracture with extension to medial malleolus and check the CT to define the extent of the injury completely. And then we underwent open reduction and screw fixation for the fracture. As a result, we present four cases of two part triplane fracture with extension with review of related literatures.

Purpose: The purpose of this study was to evaluate the frequency of troughing and stress fracture, which are the major complications of scarf osteotomy, and to suggest methods to prevent these complications. Materials and Methods: We reviewed 243 cases of 137 patients treated with the scarf osteotomy for hallux valgus from January 2005 to December 2012. The mean follow-up period was 2.8 years. During the scarf osteotomy, a long oblique longitudinal osteotomy was performed in order to decrease the possibility of troughing and stress fracture. Radiographs of lateral view of the foot were obtained and the thicknesses of the first metatarsal base at the sagittal plane were measured and compared. Results: There was no troughing during fragment translation and screw fixation intraoperatively. Radiographs of lateral view of the foot taken preoperatively and at the last follow-up showed that the mean thickness of the first metatarsal was 22.4 mm preoperatively and 21.6 mm at the last follow-up, with a mean difference of 0.8 mm. And no stress fracture was observed. Conclusion: To prevent troughing and stress fracture, a long oblique longitudinal cut, parallel to the first metatarsal plantar surface, was performed, making both ends of the proximal segment truncated cone-shape, and securing the strong bony strut of the proximal segment. No troughing or stress fracture was experienced with scarf osteotomy.

An aneurysmal bone cyst (ABC) can occur in many parts of the human body, but a primary ABC of the talus is extremely rare. ABCs are benign, but aggressively growing tumors that usually occur in the first two decades of life. Patients mainly complain of pain, limited movement of the involved joint or a palpable mass. Pain may worsen suddenly because of pathological fractures. If not treated properly, ABC has a risk of local recurrence, followed by the destruction of the joint and a significant functional deficit. While the complete removal of the bone tumor is essential, it is also important to treat the resultant bone defect after removal. The talus has an important part to play in weight-bearing. Therefore, an appropriate bone graft is required for large bone defects that occur after an ABC removal from the talus. We report a primary ABC of the talus in a 28-year-old male that was treated by curettage and a bone pillar pattern graft of autologous tricortical iliac crest bone. The patient had an excellent functional outcome with early weight-bearing, and there was no recurrence at 16 months of follow-up.
