Purpose: This study was designed to investigate the usefulness of extensile lateral approach for accurate reduction and rigid internal fixation in comminuted intraarticular fractures of calcaneus. Materials and Methods: From October 2002 to May 2007, we managed 55 patients (62 cases) with open reduction and internal fixation using extensile lateral approach. Among these, 38 patients (43 cases) who underwent preoperative and postoperative CT scan were enrolled. All patients were evaluated over 24 months after surgery. Bohler angle and Gissane angle on plain X-ray, displacement and step-off of articular surface of calcaneus on CT scan were measured and we compared the difference between preoperative and postoperative value of them. Clinical results were assessed by using AOFAS Ankle-Hindfoot Scale. Results: The average Bohler angle was restored from $6.8^{\circ}$ to $23.5^{\circ}$ and Gissane angle was improved from $116.4^{\circ}$ to $113.5^{\circ}$ after operation. The average distance of displacement was restored from 4.2 mm to 1.4 mm and step-off of articular surface was recovered from 5.1 mm to 1.3 mm. Clinical results were excellent in 17 cases, good in 18 cases, fair in 3 cases, and poor in 5 cases. 10 cases developed postoperative complications such as skin necrosis, heel pain, limitation of motion of ankle and subtalar arthritis. Conclusion: The extensile lateral approach is valuable for the comminuted intraarticular fractures of calcaneus that enables accurate anatomical reduction and rigid internal fixation by providing direct exposure of subtalar joint.

The effects of ingredients added (first cutting ingredients vs. both first and second cutting ingredients), and cooking method (smoking vs. boiling) on product quality and volatile compounds were examined for low-fat and regular-fat sausages. Regular-fat sausages had slightly higher pH values (6.2-6.3) than those (6.1-6.2) of low-fat counterparts. However, the pH values of the sausages were not significantly affected by the different ingredients and cooking methods (p>0.05). Approximately 30 volatile compounds were identified from these comminuted sausages. The headspace concentrations of 4-methyl-1-[1-methylethyl]-3-cyclohexen-1-ol, ${\alpha}$- terpenyl acetate, eugenol, trans-caryophyllene and myristicine were lower in low-fat and regular-fat sausages containing the first cutting ingredients alone, than in those with both cutting ingredients. The volatile compounds of the smoked comminuted sausages were mostly phenols and hetero-compounds, and a lot of volatile compounds were shown before the retention time (RT) of 30 min. However, not many volatile compounds were detected in the boiled sausages prior to the RT of 30 min.

The checkrein deformity describes tethering of the flexor hallucis longus tendon, which mainly occurs after fracture of the distal tibia. The deformity increases with dorsiflexion of the ankle and decreases or disappears with plantarflexion of the ankle. In some cases, the deformity may occasionally include the second and third toes. In the current study, the authors experienced secondary checkrein deformity of all lesser toes after open reduction and plate fixation for comminuted fracture of the calcaneus. As a treatment, plate and screws were removed, followed by an additional medial incision which showed a partially ruptured flexor digitorum longus tendon with severe adhesion. Resection of the adhesed tendon and tenodesis of its distal portion to the flexor hallucis longus was performed for correction of the checkrein deformity. Then the lessor toe checkrein deformity recovered immediately. The authors report on this rare lessor toe checkrein deformity after calcaneal fracture fixation with a review of literature.

This study was conducted to evaluate physicochemical and textural properties, and antimicrobial effects of low-fat comminuted sausages manufactured with sodium lactate $(3.3\%,\;SL)$ and various levels $(0.1\~0.3\%)$ of grapefruit seed extract (GSE, DF-100) during refrigerated storage for 10 weeks. Low-fat comminuted sausages (LFCS) has pH ranges of $6.09\~6.26,\;74\~76\%$ moisture, $<3\%\;fat,\;16\~17\%$ protein. The addition of SL $(3.3\%)$ and GSE with various levels $(0.1\~0.3\%)$ didn't impair water holding capacity (WHC), vacuum purge (VP) and Hunter color values (L, a, b). LFCS containing SL $(3.3\%)$ increased hardness and chewiness, whereas most TPA values were not affected by the addition of various levels $(0.1\~0.3\%)$ of GSE. LFCS containing $0.2\%\;or\;0.3\%$ GSE retarded the microbial growth of Listeria monocytogenes(LM). The addition of $0.3\%$ GSE in LFCS showed similar antimicrobial effect to $3.3\%$ SL, which kept $10^3 CFU/g$ until 10 weeks of refrigerated storage. Yellowness, VP and cohesiveness tended to be increased with increased storage time. These results indicated that the addition of $0.3\%$ GSE as a replacer for synthetic particularly paI1icuiarly inhibited the microbial growth of LM, resulting in antimicrobial effect similar to those of $3.3\%$ SL treatment without quality defects.

This paper describes rapid prototyping (RP) and reverse engineering (RE) application for orthopedic surgery planning to improve the efficiency and accuracy of the orthopedic surgery. Using the symmetrical characteristics of the human body, CAD data of undamaged bone of the injured area are generated from a mirror transformation of undamaged bone data for the uninjured area. The physical model before the injury is manufactured from Poly jet RP process. The surgical plan, including the selection of the proper implant, pre-forming of the implant and decision of fixation positions, etc., is determined by a physical simulation using the physical model. In order to examine the applicability and efficiency of the surgical planning technology, two case studies, such as a distal tibia comminuted fracture and an iliac wing fracture of pelvis, are carried out. From the results of the examination, it has been shown that the RP and RE can be applied to orthopedic surgical planning and can be an efficient surgical tool.

This is a report of cases that post-operative orocutaneous through & through open wounds are healed & closed by wound contraction if soft tissue drainage was well established, which seldom is interfered with by local or systemic abnormalities. Authors also found that the localization & seguestration of infected mandible are far better performed by natural mechanisms than by cutting across involved bone.

Distal tibia fractures were mainly caused by high energy trauma and the lower legs were enveloped in poor soft tissue. Therefore, there are many open fractures and concomitant soft tissue injuries in distal tibia fractures. For the restoration of ankle function, the surgical treatment was performed in distal tibia fractures. However, it is difficult to treat the distal tibia fracture surgically. There are many complications in distal tibia fracture due to highly comminuted fracture and poor soft tissue condition. There are many surgical methods for distal tibia fractures, such as, external fixator, intramedulary nailling, open reduction & internal fixation, and minimally invasive plate osteosynthesis. We reviewed the surgical treatments of distal tibia fractures.

To purpose of this study was to evaluate clinical results between rheumatoid arthritis shoulder cases and traumatic proximal humerus fracture cases. Fourteen patients who had been shoulder hemiarthroplasties between March 1991 to July 1996, six had rheumatoid arthritis and eight had comminuted proximal humerus fracture by the various trauma. Neer II prothesis were implanted in twenty cases and global prothesis were implanted in two cases. The follow up period was 15 months to 36 months. To evaluate this study, we used the UCLA shoulder rating. We were able to follow up thirteen cases for more than fifteen months, of which five cases had excellent, five cases had good, two cases had fair and one case had poor. And the results were better for patients with rheumaroid arthritis than for patients with trauma.

A 1.4 kg adult great homed owl was presented to the University of Missouri-Columbia Veterinary Teaching Hospital after being found by the side of the highway. Physical examination revealed soft tissue injuries to the left wing and leg, and good body condition (body score 4/5). The radiographs revealed comminuted fracture of the diaphysis of the left tibiotarsus (severe) and ulna (mild). Closed reduction of the fracture was performed to the left tibiotarsus and ulna. System combining an intramedually (IM) Kirschner pin, IM Kirschner pin for external skeletal fixation, and polymethylmethacrylate was used for fracture repair. At 13 weeks, radiographs revealed that bridging callus was well formed over cortices of the fracture area. No physical, behavioral, or other assessable impairment was found during the rehabilitation period.

To avoid external facial scar which resulted from ordinary infraorbital and lateral eyebrow incision in surgical treatment of zygomatic tripod fractures, the author used intraoral incision and K-wire fixation method in 37 selected patients. This method contraindicated for the patient with multiple comminuted zygomatic fracture, patient combined with hard palatal fracture, and patient combined with herniated orbital floor fracture. The advantages of this method are simple, no external facial scar, and operate under direct visual field. The postoperative results were satisfactory. Balanced facial symmetry and good cosmetic results were obtained.
