Stiffness of the elbow joint is relatively common after trauma, ectopic ossification, bum, postoperative scar, and etc. Mild flexion deformity can be reduced by use of active or passive motion exercise, dynamic sling, hinged distractor device, or turnbuckle orthosis. But these methods have disadvantages of difficulty in gaining acceptable range of motion only with stretching exercise, re-contracture after conservative managements and poor results that flexion contracture remained. The common described operative exposures for treatment of the stiff elbow are anterior, lateral, posterior, and medial approach. Through Anterior, lateral and medial approach each has not access to all compartments of the elbow. But, posterior approach has benefits that access to posterior, medial and lateral aspects of the elbow and as needed, fenestration to the olecranon fossa that produces a communication between the anterior and posterior compartments of the elbow are possible. From June 1991 through April 1997, 11 patients who had posttraumatic stiff elbow, were treated with debridement arthroplasty through the posterior approach. The purpose of this study are to introduce technique of the debridement arthroplasty and to evaluate final outcomes. With regarding to preoperative pain degree, mild degree matches to 3 cases, moderate to 3 cases, and severe to 2 cases. In preoperative motion, flexion was average 85° and extension was 30°. Postoperatively nine patients had got the complete relief of pain and two patients continued to have mild pain intermittentely. Postoperative flexion improved to 127° and extension to 2°, so that elbow flexion had improved by an average of 42° and elbow extension by 28°. On the objective scale all patients had good or excellent results and they all felt that they were improved by operation. Debridement arthroplasty is one of excellent procedures for the intractable stiff elbow if it is not unstable or it has not incongrous. But it need a meticulous operative technique and a well-programmed rehabilitation.

Objective : There is a lack of knowledge regarding whether decompression is necessary in treating patients with epidural spinal cord compression (ESCC) grade 2. The purpose of this study was to compare the outcomes of minimally invasive surgery (MIS) without decompression and conventional open surgery (palliative laminectomy) for patients with hepatocellular carcinoma (HCC) spinal metastasis of ESCC grade 2. Methods : Patients with HCC spinal metastasis requiring surgery were retrospectively reviewed. Patients with ESCC grade 2, medically intractable mechanical back pain, a Nurick grade better than 3, 3-6 months of life expectancy, Tomita score ${\geq}5$, and Spinal Instability Neoplastic Score ${\geq}7$ were included. Patients with neurological deficits, other systemic illnesses and less than 1 month of life expectancy were excluded. Thirty patients were included in the study, including 17 in the open surgery group (until 2008) and 13 in the MIS group (since 2009). Results : The MIS group had a significantly shorter operative time ($94.2{\pm}48.2minutes$ vs. $162.9{\pm}52.3minutes$, p=0.001), less blood loss ($140.0{\pm}182.9mL$ vs. $1534.4{\pm}1484.2mL$, p=0.002), and less post-operative intensive care unit transfer (one patient vs. eight patients, p=0.042) than the open surgery group. The visual analogue scale for back pain at 3 months post-operation was significantly improved in the MIS group than in the open surgery group ($3.0{\pm}1.2$ vs. $4.3{\pm}1.2$, p=0.042). The MIS group had longer ambulation time ($183{\pm}33days$ vs. $166{\pm}36days$) and survival time ($216{\pm}38days$ vs. $204{\pm}43days$) than the open surgery group without significant difference (p=0.814 and 0.959, respectively). Conclusion : MIS without decompression would be a good choice for patients with HCC spinal metastasis of ESCC grade 2, especially those with limited prognosis, mechanical instability and no neurologic deficit.

This study was conducted to evaluate and analyze fractures types, sites and surgical approach of wild birds in Korea. The study was conducted on data collected for fracture lesion sites, species, outcomes, surgical methods, treatments and medical records from wildlife centers in South Korea. All birds were subjected to clinical examination, followed by surgical invasion and post-operative care. Fractures were more common in adult non-raptor species (51.57%) as compared to raptors (48.43%). Of the 254 cases evaluated, maximum cases comprised ulnar fractures (29.70%), followed by radial (21.76%) and humeral fractures (17.35%). Treatment procedures at 340 fracture sites were maximally treated with figure-8 bandage (33.07%), external skeletal fixator-intramedullary pin (ESF+IM tie-in fixation) (20.86%), and other varied procedures. All birds were kept indoors till recovery. Treatment outcomes were dependent on the type of bone fractured and surgical method applied. Based on the surgical treatments and outcomes, birds were kept hospitalized, and released or euthanized. The findings of this study provide information for veterinarians regarding the fractures sites, basic database for the species and outcomes of fracture repair in wild birds.

Here we present a 43-year-old man who was brought with a self-inflicted cut throat injury; 18 hours after the suicidal attempt. On examination a deep 12 cm cut at the level of the hyoid bone exposing the posterior pharyngeal wall was seen. Emergency surgery with primary repair, tracheostomy and feeding gastrostomy was done. Post-operative period was uneventful and patient recovered without any speech or swallowing abnormalities. Through this article we would like to stress that even in cases of frightening ghastly wounds, by maintaining simple surgical principles we can achieve good outcomes.

Recently, the incidence of Achilles tendon rupture has been increasing with an increase in the elderly and the sports population. Various kinds of surgical options have been introduced up to now. Among them, the traditional open repair is most commonly used despite the risk of re-rupture or post-operative infections, which in turn can impair the blood flow to the Achilles tendon. Therefore, minimally invasive methods to overcome these complications have been studied with excellent outcomes.

The methods of clinical applications of the foot as a free-flap donor site includes microvascular toe-to-finger transfer, free neurovascular flap transfer, first web space flap transfer, and osteocutaneous free flap transfer. We have evaluated the results of treatment for 35 patients to be undergone a microvascular reconstructive procedure with the foot as a donor site from January 1982 to June 1996. The performed operations were 16 cases of thumb reconstruction with wrap around procedure, 3 cases of tenocutaneous flap transfer, 10 cases of dorsalis pedis flap transfer, 2 cases of first web space free flap and 4 cases of toe-to-finger transfer. The follow up study was 69 months in average. Regarding to the various donor sites, morbidity was divided into five different categories: Cosmesis, Functional loss, Sensory loss, Wound complication, and Pain. According to the results of examination(35 patients), the results was excellent(25), good(9), fair(1), and poor(0). Among the categories, morbidity was higher at cosmesis. The patients under 50 years were better outcome. Among the operative methods from the foot as a donor site, thumb reconstruction with wrap around procedure showed poorest outcomes. So, We conclude that the foot as a free flap donor site is a good source for the microvascular reconstructive surgery. But, Preoperative donor site evaluation, adequate operative technique and post operative management are essential to decrease the morbidity of donor site.

Background Free-flap surgery and skin grafting can be used to reconstruct large facial defects that may result after skin cancer removal by Mohs micrographic surgery (MMS). However, these two methods may produce low postsurgical patient satisfaction with aesthetics, and free-flap surgery may produce an undue burden for the majority of skin cancer patients, who are of advanced age. Hence, the authors examined outcomes of large facial defect reconstruction using multiple flaps. Methods Among patients undergoing MMS for skin cancer at Pusan National University Hospital between January 2013 and December 2015, we evaluated 7 patients (2 males, 5 females; average age, 73.14 years) treated for large facial defects from basal cell carcinoma. Based on operative and follow-up records, we investigated the number and type of flaps used, postsurgical complications, and patients' post-surgical satisfaction. Results Two and 3 types of flaps were used for 5 and 2 patients, respectively. Most frequently used were nasolabial flaps (7 times in 6 patients) and forehead flaps (once in each of 4 patients). The average follow-up period was 14 months, with no complications-including necrosis, hematoma, or wound dehiscence-observed. Post-surgical satisfaction averaged 4.4 out of a maximum of 5 points. Conclusions Reconstruction using two or more flaps for large facial defects after skin cancer removal using MMS produced satisfactory outcomes while preventing aesthetic problems. Practitioners should consider using multiple flaps when choosing a reconstruction method for large facial defects following skin cancer removal.

Purpose: The prognosis of total hip replacement (THR) after open reduction and internal fixation (ORIF) versus THR following non-operative treatment of acetabular fractures is unclear. Few studies have been conducted in this regard. Therefore, the purpose of the current study was to perform an assessment and compare the functional outcomes for study subjects in the ORIF and non-ORIF groups during the follow-up period compared to baseline. Materials and Methods: This longitudinal comparative study, which included 40 patients who underwent THR for either posttraumatic arthritis after fixation of an acetabular fracture or arthritis following conservative management of a fracture, was conducted for 60 months. Twenty-four patients had undergone ORIF, and 16 patients had undergone nonoperative/conservative management for acetabular fractures. Following THR, the patients were followed up for monitoring of functional outcomes for the Harris hip score (HHS) and comparison between the ORIF and non-ORIF groups was performed. Results: The HHS showed significant improvement in both ORIF and non-ORIF groups. At the end of the mean follow-up period, no significant variation in scores was observed between the groups, i.e., ORIF group (91.61±6.64) compared to non-ORIF group (85.74±11.56). A significantly higher number of re-interventions were required for medial wall fractures and combined fractures compared to posterior fractures (P <0.05). Conclusion: THR resulted in improved functional outcome during follow-up in both the groups; however, the ORIF group was observed to have better functional outcome. Re-intervention was not required for any of the posterior fractures at the end of the mean follow-up period.

Objective : Gamma knife radiosurgery (GKRS) is the least invasive surgical option for patients with trigeminal neuralgia (TN). However, the indications and long term outcomes of GKRS are still controversial. Additionally, a series with uniform long-term follow-up data for all patients has been lacking. In the present study, the authors analyzed long-term outcomes in a series of patients with TN who underwent a single GKRS treatment followed by a minimum follow-up of 60 months. Methods : From 1994 to 2009, 40 consecutive patients with typical, intractable TN received GKRS. Among these, 22 patients were followed for >60 months. The mean maximum radiation dose was 77.1 Gy (65.2-83.6 Gy), and the 4 mm collimator was used to target the radiation to the root entry zone. Results : The mean age was 61.5 years (25-84 years). The mean follow-up period was 92.2 months (60-144 months). According to the pain intensity scale in the last follow-up, 6 cases were grades I-II (pain-free with or without medication; 27.3%) and 7 cases were grade IV-V (<50% pain relief with medication or no pain relief; 31.8%). There was 1 case (facial dysesthesia) with post-operative complications (4.54%). Conclusion : The long-term results of GKRS for TN are not as satisfactory as those of microvascular decompression and other conventional modalities, but GKRS is a safe, effective and minimally invasive technique which might be considered a first-line therapy for a limited group of patients for whom a more invasive kind of treatment is unsuitable.

Objective : We evaluated postoperative outcomes in patients who have lumbar foraminal or extraforaminal disc herniation (FELDH) and suggested the risk factors for poor outcomes. Methods : A total of 234 patients were selected for this study. Pre- and post-operative Visual Analogue Scale (VAS) and Korean version Oswestry Disability Index (KODI) were evaluated and the changes of both score were calculated. Outcome was defined as excellent, good, fair, and poor based on Mcnab classification. The percentage of superior facetectomy was calculated by using the Maro-view 5.4 Picture Archiving Communication System (PACS). Results : Paramedian lumbar discectomy was performed in 180 patients and combined lumbar discectomy was performed in 54 patients. Paramedian lumbar discectomy group showed better outcome compared with combined discectomy group. p value of VAS change was 0.009 and KODI was 0.013. The average percentage of superior facetectomy was 33% (range, 0-79%) and it showed negative correlation with VAS and KODI changes (Pearson coefficient : -0.446 and -0.498, respectively). Excellent or good outcome cases (Group I) were 136 (58.1%) and fair or poor outcome cases (Group II) were 98 (41.9%). The percentage of superior facetectomy was 26.5% at Group I and 42.5% at Group II. There was significant difference in superior facetectomy percentage between Group I and II (p=0.000). Conclusion : This study demonstrated that paramedian lumbar discectomy with preservation of facet joints is an effective and good procedure for FELDH. At least 60% of facet should be preserved for excellent or good outcomes.
