Objective : Cerebral palsy may induce harmful spastic hip adduction. We report the result of microsurgical selective obturator neurotomy, performed on 12 spastic hip adductions of 6 patients, followed clinically for at least 26 months postoperatively. Methods : Microsurgical selective obturator neurotomies, involving microsurgical resection of the anterior obturator nerve branches were performed on 6 patients from January 2000 through June 2003. All patients presented with the inability to sit and 2 patients complained of persistent, intractable pain. We used intraoperative bipolar stimulation to identify selected motor branches. Results : The procedure was performed bilaterally in all patients. In the 3 patients in whom contractures were present, microsurgical selective obturator neurotomies were accompanied by an additional tenotomy of the adductor muscles. Selective tibial neurotomy was performed on three of six patients who originally presented with a spastic ankle. Postoperatively, all spastic hip adductions were corrected more than 60 degrees in passive abduction-adduction amplitude. However, one patient who did not receive active postoperative physiotherapy demonstrated a decreased passive abduction-adduction amplitude upon follow-up. There were no surgical complications. Conclusion : We think microsurgical selective obturator neurotomy may be an effective procedure in the treatment of localized, harmful spastic hip adduction after failure of well conducted conservative treatment. As muscular contractions are often associated with spasticity of the hip adductors, an adjunctive tenotomy may be an option. Comprehensive postoperative physiotherapy is essential to improve long-term results.

Objective : We present our experience of microvascular decompression (MVD) for glossopharyngeal neuralgia (GPN) and evaluate the postoperative outcomes in accordance with four different operative techniques during MVD. Methods : In total, 30 patients with intractable primary typical GPN who underwent MVD without rhizotomy and were followed for more than 2 years were included in the analysis. Each MVD was performed using one of four different surgical techniques : interposition of Teflon pieces, transposition of offending vessels using Teflon pieces, transposition of offending vessels using a fibrin-glue-coated Teflon sling, and removal of offending veins. Results : The posterior inferior cerebellar artery was responsible for neurovascular compression in 27 of 30 (90%) patients, either by itself or in combination with other vessels. The location of compression on the glossopharyngeal nerve varied; the root entry zone (REZ) only (63.3%) was most common, followed by both the REZ and distal portion (26.7%) and the distal portion alone (10.0%). In terms of detailed surgical techniques during MVD, the offending vessels were transposed in 24 (80%) patients, either using additional insulation, offered by Teflon pieces (15 patients), or using a fibrin glue-coated Teflon sling (9 patients). Simple insertion of Teflon pieces and removal of a small vein were also performed in five and one patient, respectively. During the 2 years following MVD, 29 of 30 (96.7%) patients were asymptomatic or experienced only occasional pain that did not require medication. Temporary hemodynamic instability occurred in two patients during MVD, and seven patients experienced transient postoperative complications. Neither persistent morbidity nor mortality was reported. Conclusion : This study demonstrates that MVD without rhizotomy is a safe and effective treatment option for GPN.

Purpose: Rupture of a collateral ligament of the metacarpophalangeal joint is rare except in the thumb. The injured digit became flexed and deviated toward ulna side by the hypothenar intrinsic musculature. Incomplete rupture of a collateral ligament of the metacarpophalangeal joint can be often managed by splinting the affected digit in flexion position, however, in the case of complete tears that distraction of the ends of the ruptured collateral ligament is too great to allow repositioning by splinting. Primary repair of the ruptured collateral ligament or reattachment to bone by a pull-out wire, or tendon graft technique appears to be adequate. Methods: We report a case of instability of fifth metacarpophalangeal joint due to complete rupture of radial collateral ligament. This 18-year-old male presented pain in his right outstretched hand after trauma. The diagnosis was obtained by physical examination and simple radiography. Because of persistent instability after the initial conservative treatment, open reduction and repair surgical treatment was required. Results: The fifth metacarpophalangeal joint became free of pain and stable under forced lateral deviation. Postoperative results showed good metacarpophalangeal joint function and stability during 8 months follow-up period. Conclusion: Because of the interposition of the sagittal band between the ruptured ends of radial collateral ligament such as Stener-like lesion of the thumb, surgical repair of metacarpophalangeal joint collateral ligament of the finger was justified in case of complete laxity in full flexion.

Purpose: Achilles tendon rupture is a frequently encountered ankle pathology associated with a substantial burden of intense pain and functional deficits. Chronic Achilles tendon ruptures with considerable defects pose intricate repair challenges that are often marred by complications such as re-rupture and persistent pain. Various treatment methods, including allograft transplantation, have been proposed, but the literature on this technique is limited. In this study, we propose a surgical approach utilizing allotendon transplantation and a calcaneal tunneling technique and provide clinical evaluation details. Materials and Methods: Fifteen patients with chronic Achilles tendon ruptures treated with allotendon between 2020 and 2022 were included in the study. Patients were evaluated at 1, 3, and 6 months postoperatively using Visual Analog Scale (VAS) scores and Achilles Tendon Total Rupture Scores (ATRSs). Complications were assessed postoperatively. Results: The average VAS score was 7 before surgery, 7.3 immediately after surgery, and 4.3 at 1 month, 2.5 at 3 months, and 1.3 at 6 months after surgery. Because the sample was limited to 15 individuals and distributions were non-normal, the analysis was conducted using the non-parametric Wilcoxon's signed-rank test, and statistical significance was accepted for p-values<0.05. Results showed a significant improvement in ATRS and VAS scores versus preoperative and immediate postoperative values. VAS scores showed a decreasing trend after surgery, whereas average ATRS scores increased from 14 before surgery, 33.8 at 1 month, 82.7 at 3 months, and 93.9 at 6 months. Conclusion: This study suggests that allograft transplantation using the described calcaneal tunnel technique provides an effective treatment for chronic Achilles tendon ruptures. However, extensive research and long-term clinical trials are required to validate and better understand the technique's efficacy.

Objective : Although many treatment modalities have been introduced for trigeminal neuralgia (TN), the long-term clinical results remain unsatisfactory. It has been particularly challenging to determine an appropriate treatment strategy for patients who have responded poorly to initial therapies. We analyzed the surgical outcomes in TN patients who failed prior treatments. Methods : We performed a retrospective analysis of 37 patients with recurrent or persistent TN symptoms who underwent surgery at our hospital between January 2010 and December 2014. Patients with follow-up data of at least one year were included. The prior treatment modalities of the 37 patients included microvascular decompression (MVD), gamma knife radiosurgery (GKRS), and percutaneous procedures such as radiofrequency rhizotomy (RFR), balloon compression, and glycerol rhizotomy (GR). The mean follow-up period was 69.9 months (range : 16-173). The mean interval between the prior treatment and second surgery was 26 months (range : 7-123). We evaluated the surgical outcomes using the Barrow Neurological Institute (BNI) pain intensity scale. Results : Among the 37 recurrent or persistent TN patients, 22 underwent MVD with partial sensory rhizotomy (PSR), 8 received MVD alone, and 7 had PSR alone. Monitoring of the surgical treatment outcomes via the BNI pain intensity scale revealed 8 (21.6%) patients with a score of I, 13 (35.1%) scoring II, 13 (35.1%) scoring III, and 3 (8.2%) scoring IV at the end of the follow-up period. Overall, 91.8% of patients had good surgical outcomes. With regard to postoperative complications, 1 patient had transient cerebrospinal fluid rhinorrhea (2.7%), another had a subdural hematoma (2.7%), and facial sensory changes were noted in 8 (21.1%) patients after surgery. Conclusion : Surgical interventions, such as MVD and PSR, are safe and very effective treatment modalities in TN patients who failed initial or prior treatments. We presume that the combination of MVD with PSR enabled us to obtain good short- and long-term surgical outcomes. Therefore, aggressive surgical treatment should be considered in patients with recurrent TN despite failure of various treatment modalities.

Background: A retrospectiye study was done for understanding morbidity and mortality after major lung resection. Material and Method: From June 1994 to August 1998, 203 patients received major lung resections for various causes. There were 142 males and 62 females with a mean age of 47.5 years. Initial complains were cough in 47.8%, sputum in 33.0%, hemoptysis or blood-tinged sputum in 23.2%, dyspnea in 18.2%, chest pain in 15.3%, weight loss in 10.8%, fever and chill in 4.9%. There were no complaints in 5.9% of the total patients. The underlying diseases were lung tumor(102 cases/50.2%), bronchectasis(28 cases/13.8%), aspergillosis(24 cases/1.8%), tuberculosis(20 cases/9.9%) and others (29 cases/66.5%) and pneumonectomy(68 cases/33.5%). The postoperative complications were classified as : empyema, BPF, respiratory problem, persistent air leakage over 7 days, arrhythmia, ventilator applied over 24 hours, bleeding, wound infection and chylothorax. The postlobectomy complications were revealed as follow: empyema(3.7%), BPF(2.2%), respiratory problem(5.2%), persistent air leakage over 7days(8.9%), arrhythmia(2.2%), ventilator applied over 24 hours(2.2%), bleeding(1.5%), wound infection(2.9%), chylothorax(0.7%). The postpneumonectomy complications were revealed as follow : empyema(5.9%), BPF (5.9%), respiratory problem(17.6%), persistent air leakage over 7days(0%), arrhythmia(5.4%), ventialtor apply over 24 hours(7.4%), bleeding (7.4%), wound infection(2.9%) and chylothorax(1.5%). Reoperation was done in 8 cases (4.0%). There were 5.8% operative mortalities in pneumonectomy and 0.7% in lobectomy.

Purpose: Retronychia is the embedding of the nail into proximal nail fold. Retronychia starts with disruption of the longitudinal growth of the nail. With the growth of a new nail, the old one is pushed upwards and backwards. This leads to embedding of the top nail into the ventral aspect of the proximal nail fold and results with chronic paronychia. We present a case of retronychia that was rarely reported in the literature. Methods: A 46-year old female presented with a 3-month history of painful right first, 2nd, 3rd toenail changes. Although she was initially treated with broad spectrum antibiotics, she did not response to therapy. Later, she presented to our department because of progressively worsening pain that impaired her walking. Physical examination revealed with proximal nail fold erythema, painful swelling, yellowish nail discoloration, and distal onycholysis. Bacterial and fungus culture showed no organism. Treatment was surgical nail avulsion under local anesthesia. Results: The postoperative course was uneventful. 10 months later, the patient had a normal growing nail and was free of symptoms. Conclusion: We report a case of retronychia on toenail. Retronychia is a proximal nail plate ingrowth into the proximal nail fold which is associated with multiple generations of nail plate misaligned beneath the proximal nail. Management consisted of simple avulsion of superimposed nail. Retronychia is suspected with a persistent paronychia, particularly in the setting of trauma. Avulsion of the top nail confirms the diagnosis and may be curative if the underlying nail appears healthy.

오스굿씨 병은 일반적으로 보존적 방법으로 치료하지만 이에 호전되지 않는 지속적 혹은 재발성 통증이 있는 경우 수술적 가료가 필요한 경우가 있다. 대부분의 저자들이 슬개건 원위 골부착 부위에 골편이 존재하는 경우에 이를 제거하는 것으로 좋은 결과를 얻을 수 있다고 보고해 왔다. 저자들은 경골결절 전면부에 절개를 가하여 슬개건을 박리 후 골편을 제거하는 기존의 방식대신 관절경을 이용하여 슬개건의 뒤쪽으로부터 골편에 접근하여 골편을 제거하는 수기를 보고하고자 한다. 관절경을 이용한 오스굿씨 병의 골편제거술은 슬개건에의 손상을 최소화 할 수 있고, 빠른 술후 회복을 기대할 수 있으며, 경골 결절 전방부에 절개를 가하지 않음으로써 절개창 치유 후에 잔존할 수 있는 무릎을 꿇을 때의 반흔부 불편감의 발생을 예방할 수 있고, 보다 미용적이라는 장점이 있는 술식으로 사료된다.

배경: 이 연구는 외상성 기관-기관지 손상의 특징적인 임상 증상 및 영상학적 소견 등에 대하여 알아보고자 하였다. 대상 및 방법: 2003년 1월부터 2009년 12월까지 본원 응급실을 통해서 내원한 외상 환자들 중에서 수술을 통해서 외상성 기관-기관지 손상으로 진단된 6명의 환자를 대상으로 하였다. 외상의 종류, 동반된 손상, 진단 방법 및 수술까지 걸린 시간, 수술 소견 및 수술 방법, 예후 등에 대해서 조사해 보고 후향적으로 진단에 중요한 인자 등을 알아 보았다. 결과: 손상의 원인으로는 교통사고가 1명, 낙상 및 흉부에 강한 압박을 받은 경우가 5명이었다. 주 증상으로 피하기종, 호흡 곤란, 통증 등이 있었으며 영상소견으로는 기흉, 종격동 기종, 혈흉, 늑골 골절, 폐좌상 등이 있었다. 기관지 내시경을 시행하지 않은 상태에서 2명에서는 흉부 CT 소견에서 기관-기관지 손상이 의심되었지만 나머지 4명에서는 의심하지 못했다. 수상 부위는 기관부위가 2예, 기관지가 4예 있었다. 수술은 개흉술을 통한 일차 문합을 시행하였고 수술 후 사망과 문합 부위 유출은 없었으며 1명에서 술 후 성대 마비가 있었다. 진단에 도움이 되는 특징적인 소견으로는 흉관 삽입 후 음압의 적용에도 불구하고 지속적인 심한 폐 허탈이 가장 중요한 소견이었으며, 흉부 CT에서의 기관-기관지의 주행 경로의 단절이 진단에 중요하였다. 결론: 외상성 기관-기관지 손상은 의심하지 않으면 진단이 쉽지 않으나, 특징적인 흉관 삽입 후의 임상 증상과 영상 소견은 진단에 큰 도움을 주었다.
