Purpose: To evaluate the clinical and radiological results of internal fixation with tension band wiring for the fracture at the base of fifth metatarsal bone. Materials and Methods: From January 2008 to December 2009, 15 cases with displaced fracture at the base of fifth metatarsal were analyzed and average follow up period was 13.8 months. Lawrence classification was used to classify fracture type. We evaluated clinical results by American Orthopedic Foot Ankle Society (AOFAS) midfoot score and radiological results by union time. Complications was also checked. Results: According to classification, zone I fracture were 11 cases and zone II fracture were 4 cases. Bony union was achieved in all cases after 7 weeks. In the final follow-up, average AOFAS score was 94. There were no complications except hardware irritation. Conclusion: Satisfactory results were obtained after tension band wiring for the fifth Metatarsal base fracture in zone I fracture or comminuted zone II fracture for which it is not easy to be fixed with screw.

Operative treatment including a bone graft and an internal fixation was done in a fifteen-year old wrestler with transverse olecranon stress fracture. At 6 weeks after the operation, he could start active muscle strengthening exercise and returned to the previous level of exercise at 6 monthes after surgery. Conservative treatment including resting and muscle strengthening exercise was performed in an eighteen-year old baseball player with oblique olecranon stress fracture. At the follow-up of three months, he could start staged throwing exercise without pain or tenderness. He returned the previous level of throwing following strengthening exercise for 6 months.

Purpose: Absorbable implants are frequently used to fix facial bone fractures, because they are radiolucent and compatible with magnetic resonance imaging (MRI). Despite their increasing usage, however, there have been few reports about their long-term side-effects. In this paper, a case in which absorbable implants led to a foreign body reaction 17 months after their insertion is presented. Methods: A previously healthy 19-year-old male fell from a flight of stairs and visited the authors' hospital with right periorbital pain. Zygomaticomaxillary fracture involving right orbital floor was detected via a facial bone computed tomography (CT). Internal fixation with absorbable implants was followed by open reduction. 17 months after the surgery, the patient complained of localized periorbital swelling. Removal of the granulomatous lesion including the absorbable implants along with their biopsy and culture was performed. Results: The granulomatous lesion around the implants was firm and extended into the maxillary sinus. The histologic finding showed a microabscess with a foreign body reaction. Methicillin-sensitive Staphylococcus aureus growth was confirmed in the culture. No definite abnormal symptoms ensued after the complete removal. Conclusion: A microabscess-forming granulomatous lesion around the absorbable implant can cause delayed symptomatic foreign body reaction despite its rare occurrence. Complete removal of the lesion including implants is expected to have a successful outcome if it is encountered.

Pectus Excavatum is a congenital anomaly of the anterior chest wall with a sharp concave curvature of the body of the sternum, from above downward and from side to side, especially just before the junction of gladiolo-xiphoid. We have experienced 14 cases of Pectus Excavatum with several operative procedures, i.e., Ravitch operation in 1 case, Wada operation [Sternal turn-over} in 3 cases, Wada operation and K-wire splint in 5 cases, Modified Wada operation [Rectus Abdominis muscle pedicle attached sternal turn-over] in 5 cases. Nearly all patients developed flail chest treated with internal fixation, and necrotic chondritis was developed postoperatively and treated with excision and curettage in one case with Wada operation. Follow-up Vertebral Index showed 48% preoperatively and 33% postoperatively, average decrement of 15%. We report 14 cases of Pectus Excavatum and their operative treatments.

Osborne-Cotterill lesion is an osteochondral fracture located in the posterolateral margin of the humeral capitellum, which may be associated with a defect of the radial head after an elbow dislocation. This lesion causes instability by affecting the lateral ulnar collateral ligament over its capitellar insertion, which is associated with a residual capsular laxity, thereby leading to poor coverage of the radial head, and hence resulting in frequent dislocations. We present a 54-year-old patient, a physician who underwent trauma of the left elbow after falling from a bike and suffered a posterior dislocation fracture of the elbow. The patient subsequently presented episodes of instability, and additional work-up studies diagnosed the occurrence of Osborne-Cotterill lesion. An open reduction and internal fixation of the bony lesion was performed, with reinsertion of the lateral ligamentous complex. Three months after surgery, the patient was asymptomatic, having a flexion of 130° and extension of 0°, and resumed his daily activities without any limitation. Currently, the patient remains asymptomatic 2 years after the procedure. Elbow instability includes a large spectrum of pathological conditions that affect the biomechanics of the joint. The Osborne-Cotterill lesion is one among these conditions. It is a pathology that is often forgotten and easily overlooked. Undoubtedly, this lesion requires surgical intervention.

Photosynthesis and transpiration rates were simultaneously measured in attached sunflower leaves(Helianthus annuusL. cv. Russian Mammoth) during exposure to $NO_2$ and $O_3$ to determine the effect of mixed gan on photosynthesis and the stomatal aperture. The application of $O_3$ alone reduced both the net photosynthetic and transpiration rates. An analysis of the $CO_2$ diffusive resistances indicated that the main cause affecting photosynthesis reduction during $O_3$ exposure was not the internal gas phase of the leaf $(rCO_2^{liq})$ but rather the liquid phase or mesophyll diffusive resistance $(rCO_2^{liq})$, suggesting that there is a very concomitant relation between photosynthetic reduction and $rCO_2^{liq}$. The application of NO2 alone caused a marked reduction of the net photosynthesis yet no significant reduction of transpiration, indicating that NO2 affects the $CO_2$ fixation processes with no inluence on the stomatal aperture. A greter reduction in the photosynthesis of sunflower plants was caused by the application of $NO_2$ alone as compared to a combination of $NO_2$ and $O_3$. $NO_2$ alone reduced the photosynthetic rate by 90%, whereas a mixture of NO2 and O3 reduced it by 50%.

Little literature exists about the risk of atypical femoral fracture in patients received zoledronic acid for prevention of skeletal metastasis. We report an atypical subtrochanteric femoral fracture in a patient with multiple myeloma received zoledronic acid. The patient was treated by closed reduction and internal fixation with cephalomedullary nailing.

The avulsion fracture of the calcaneal tuberosity is rare injury. Usually, it occurs from indirect trauma in old patients with osteoporosis or in patients with diabetic neuropathy. Especially, the bone and joint damage occurred in active patient with severe sensory loss or arthropathy related to nerve damage regardless of the cause is referred to neuropathic arthropathy. Generally, a patient with nondisplacement or minimally displacement is treated by conservative therapy and a patient with severe displacement is treated by open reduction and internal fixation. We experienced a 33 years-old woman with diabetes mellitus who had the displaced avulsion fracture of the calcaneal tuberosity without significant trauma and did not treat. We report upon this case at the 2 years follow-up.

Theoretically, panfacial bone fractures involve all three areas of the face: frontal bone, midface, and mandible. In practice, when two out of these three areas are involved, the term "panfacial bone fracture" has been applied. We can use physical examination, simple radiologic examination, and computed tomography study for diagnosis. Linear fracture are treated by conservative treatment. But, most of panfacial bone fracture patients need to be treated by open reduction and internal fixation. Facial width is most important thing that we need to care during operation. There are many ways about sequence like "top to bottom," "bottom to top," "outside to inside," or "inside to outside" and the authors prefer "top to bottom" and "outside to inside" ways. The authors apply arch bar from the first of surgery and then, set frontal bone fracture, midface fracture and mandible fracture in sequence. Usually, we remove the stitches for 5 days after surgery and the intraoral stitch removed after 2 weeks. Usually arch bar is going to be removed 4 weeks after surgery. We could get acceptable results with the above way.

We have reviewed seven cases of fracture-separation of the distal humeral epiphysis, one of which was initially misdiagnosed as a fracture of the lateral condyle. There were difficulties in making the diagnosis. The injury must be distinguished from an elbow dislocation and a fracture of the lateral humeral condyle. All seven patients revealed posteromedial displacenemt of the distal humeral epiphysis on initial x-rays. Three patients were treated by closed reduction and cast immmobilization, and four patients by open reduction and internal fixation. All three patients with conservative treatment had slight cubitus varus(under 5 degrees). Two patients with operative treatment had significant deformities of the elbow, one 25 degrees of valgus and one 20 degrees of varus. In treatment of these injuries, accurate evaluation of the state of reduction is most important. We got acceptable results with a conservative treatment.
