Purpose: Regardless of potential and actual complications, the sesamoidectomy either tibial side or fibular side or both, had been used as a surgical option for various pathologic conditions. The objective of this cadaveric study was to identify the changes of range of motion of great toe after sesamoidectomy. Material and Methods: Eight fresh cadaver legs were used. The angular changes of the hallucal articulations were measured by traction of the flexor hallucis longus tendon at the proximal border of fibro-osseous tarsal tunnel and by traction of the extensor hallucis longus tendon at the superior border of inferior extensor retinaculum. The measurement started at neutral position and proceeded to the maximum for respective tendons. After sesamoidectomy either partial or total, same procedures were repeated and the angular changes were measured. Results: In flexion of great toe, there were significant metatarsophalangeal angular differences at 1 cm traction in total sesamoidectomy and lateral sesamoidectomy. In extension of great toe, there were significant metatarsophalangeal angular differences at more than 2 cm traction in total sesamoidectomy. In other measurements, there were no significant angular changes of the hallucal articulations. Conclusion: The sesamoidectomy resulted in change of motion of great toe. Statistical analysis showed that the significant increases in the initial flexion and maximal extension occurred with total sesamoidectomy and the significant increase in the initial flexion occurred with lateral sesamoidectomy.

Objective : In Asians, kneeling and squatting are the postures that are most often induce common peroneal neuropathy. However, we could not identify a compatible compression site of the common peroneal nerve (CPN) during hyper-flexion of knees. To evaluate the course of the CPN at the popliteal area related with compressive neuropathy using magnetic resonance imaging (MRI) scans of healthy Koreans. Methods : 1.5-Tesla knee MRI scans were obtained from enrolled patients and were retrospectively reviewed. The normal populations were divided into two groups according to the anatomical course of the CPN. Type I included subjects with the CPN situated superficial to the lateral gastocnemius muscle (LGCM). Type II included subjects with the CPN between the short head of biceps femoris muscle (SHBFM) and the LGCM. We calculated the thickness of the SHBFM and posterior elongation of this muscle, and the LGCM at the level of femoral condyles. In type II, the length of popliteal tunnel where the CPN passes was measured. Results : The 93 normal subjects were included in this study. The CPN passed through the "popliteal tunnel" formed between the SHBFM and the LGCM in 36 subjects (38.7% type II). The thicknesses of SHBFM and posterior portions of this muscle were statistically significantly increased in type II subjects. The LGCM thickness was comparable in both groups. In 78.8% of the "popliteal tunnel", a length of 21 mm to <40 mm was measured. Conclusion : In Korean population, the course of the CPN through the "popliteal tunnel" was about 40%, which is higher than the Western results. This anatomical characteristic may be helpful for understanding the mechanism of the CPNe by posture.

The Clothing expresses people's desire of beauty most directly of all cultural inheritances, and it teach us how the human culture has changed and developed. In this study researched the history of buttonholes which make the clothes more functional and beautiful. Buttons and Buttonholes is one of detailed elements they used as a fastener or as a decoration on clothing. Button have been used since ancient times, in early times long before buttons were used as fasteners they had significant decorative and symbolic value. In ancient times, clothes fastened with pins, brooches, fibular and ties. In medieval Europe, it was not until the 13th century that they used the button in functional use, and then Chong Ryung-Lk was introduced from orient, and they became popular as fasteners on clothing during the 13th century when fitted clothes replaced loose garments. Garments were laced together or fastened with buttons, until buttonholes were invented in the 13th century. But as early as the 14th century it appears that someone discovered that a loop slipped over a button, or button pushed through a slit in the cloth, would make a good clothes fastener. Many buttons made during the modern ages were convex medallions set in metal rims and decorated with partraits of famous men and women. During the modern ages, buttons, with ligh-ographed pictures, covered with celluloid of glass were popular. In the 19th century, the mass production by machine made people use the button easily, and many different material of button easily and many different material of button was made. With the begining of the 20th century. the development of plastics led to various and functional buttons. The type of buttonholes also became various, as bound buttonhole, Tailred buttonhole, Worked buttonhole, Loop buttonhole and so on. The button has many forms which were imitated by nature, or made geometrically and the appearance of the button from behind is classified by what has holes and what has holes and what has a shank, and I also classified the kinds of button by the quality of the material design and use. Like this, with the passing of the time buttons and buttonholes have changed in appearance with the change of clothes, and they have standed for something meaningful as well as fixed the opening and made clothes more beautiful.

Skull base tumors have been determined inoperable because it is difficult to accurately diagnose the extent of the involvement and to approach and excise the tumor safely. However, recently, the advent of sophisticated diagnostic tools such as computed tomography and magnetic resonance imaging as well as the craniofacial and neurosurgical advanced techniques enabled an accurate determination of operative plans and safe approach for tumor excision. Resection of these tumors may sometimes result in massive and complex extirpation defects that are not amenable to local tissue closure. The purpose of this study is to analyze experiences of skull base reconstruction and to evaluate long term survival rate and complications. All cranial base reconstructions performed from July 1993 to September 2000 at Department of Plastic and Reconstructive Surgery of the Seoul National University Hospital were observed. The medical records were reviewed and analysed to assess the location of defects, reconstruction method, existence of the dural repair, history of preoperative radiotherapy and chemotherapy, complications and causes of death of the expired patients. There were 12 cases in region II, 8 cases in region I and 1 case in region III according to the Irish classification of skull base. Cranioplasty was performed in 4 patients with a bone graft and microvascular free tissue transfer was selected in 17 patients to reconstruct the cranial base and/or mid-facial defects. Among them, 11 cases were reconstructed with a rectus abdominis musculocutaneous free flap, 2 with a latissimus dorsi muscluocutaneous free flap, 1 with a fibular osteocutaneous free flap, 2 with a scapular osteocutaneous free flap, and 1 with a forearm fasciocutaneous free flap, respectively. During over 3 years follow-up, 5 patients were expired and 8 lesions were relapsed. Infection(3 cases) and partial flap loss(2 cases) were the main complications and multiorgan failure(3 cases) by cancer metastasis and sepsis(2 cases) were causes of death. Statistically 4-years survival rate was 68%. A large complex defects were successfully reconstructed by one-stage operation and, the functional results were also satisfactory with acceptable survival rates.

Objective : The purpose of the study was to determine the clinical effects of anterior radical debridement on a series of patients with spontaneous spinal infection. Methods : We retrospectively analyzed the clinical characteristics of 32 patients who underwent surgical treatment from January 2000 to December 2005 in our department. The average follow-up Period was 33.4 months (range, 6 to 87 months). Thirty-two patients presented with the following : 23 cases with pyogenic spondylitis, eight with tuberculous spondylitis and one with fungal spondylitis. The indications for surgery were intractable pain, failure of medical management, neurological impairment with or without an associated abscess, vertebral destruction causing spinal instability and/or segmental kyphosis. Results : The study included 15 (46.9%) males and 17 (53.1%) females ranging in age from 26 to 75 years (mean, 53.1 years). Diabetes mellitus (DM) and pulmonary Tbc were the most common predisposing factors for pyogenic spondylitis and tuberculous spondylitis. Staphylococcus aureus (13%) was the main organism isolated. The most prevalent location was the lumbar spine (75%). Changes in the pain score, Frankel's classification, and laboratory parameters demonstrated a significant clinical improvement in all patients. However, there were recurrent infections in two patients with tuberculous spondylitis and inappropriate debridement and intolerance of medication and noncompliance. Autologous rib, iliac bone and allograft(fibular) were performed in most patients. However, 10 patients were grafted using a titanium mesh cage after anterior radical debridement. There were no recurrent infections in the 10 cases using the mesh cage with radical debridement. Conclusion : The findings of this study indicate that surgery based on appropriate surgical indications is effective for the control of spinal infection and prevention of recurrence with anterior radical debridement, proper drug use and abscess drainage.

Purpose: The purpose of this study was to investigate usefulness of locking compression plate (LCP) as an open reduction technique by evaluating clinical results obtained from the patients with lateral malleolar fracture treated by internal fixation using LCP after open reduction. Materials and Methods: Among the patients with lateral malleolar fracture, the 28 patients who were treated by internal fixation using Locking compression plate after an open reduction and were able to be followed up for more than 6 months were included in this study. Final postoperative evaluation was done based on the Meyer's clinical and radiologic evaluation system. Results: All cases achieved anatomical reduction and fixation of the reduction postoperatively. 28 minutes were taken meaningly from the incision to the fixation of LCP plate after the anatomical reduction. Everage bony union time was 8.2 weaks, and the result was excellent in 23 cases (82%), good in 5 cases (17%) and poor result was abscent according to the criteria of Meyer et al. One case of post traumatic arthritis and one case of superficial infection on the operation site were found, but non-union, delayed union and malunion were not occurred. Conclusion: The internal fixation after open reduction using LCP is an effective treatment method in treating lateral malleolar fracture of the ankle since it offers advantages including easy application and a greater stability due to its capability of maintaining exact anatomical reduction even though the screw does not penetrate the medial cortex of fibular to add the stability and rigidity of the fixation.

The fibula free flap has now become the most reliable and frequently used option for mandible reconstruction. Recently, three dimensional images and printing technologies are applied to mandibular reconstruction. We introduce our recent experience of mandibular reconstruction using three dimensionally planned fibula free flap in a patient with gunshot injury. The defect was virtually reconstructed with three-dimensional image. Because bone fragments are dislocated from original position, relocation was necessary. Fragments are virtually relocated to original position using mirror image of unaffected right side of the mandible. A medical rapid prototyping (MRP) model and cutting guide was made with 3D printer. Titanium reconstruction plate was adapted to the MRP model manually. 7 cm-sized fibula bone flap was designed on left lower leg. After dissection, proximal and distal margin of fibula flap was osteotomized by using three dimensional cutting guide. Segmentation was also done as planned. The fibula bone flap was attached to the inner side of the prebent reconstruction plate and fixed with screws. Postoperative evaluation was done by comparison between preoperative planning and surgical outcome. Although dislocated condyle is still not in ideal position, we can see that reconstruction was done as planned.

Reconstruction of the composite mandibular defect resulting from ablative resection of tumor involved jaw has been challenging task to the plastic surgeon. A wide variety of different techniques were used with limited success until the advent of microsurgery. The high success rate of microsurgical procedures has allowed for significant improvement in both functional and aesthetic results. A variety of free flap donor sites have been used successfully for mandibular reconstruction. Between April of 1991 and August of 1998, 20 mandibular reconstructions were performed for oncologic defects. 4 patients underwent mandibular reconstruction with pectoralis major flap, 3 patients with free nonvascularized bone graft, 1 patient with metal plate. 12 patients underwent microvascular mandibular reconstruction(8: fibula, 4: ilium). The type of free flap was determined by the requirements of the defect. Satisfactory aesthetic and functional results were achieved in all cases without significant complications. So microvascular mandibular reconstruction should be considered as primary choice in all mandibular defect without hesitation.
