Background. Nonunion of the lateral humeral condyle  are of the complex pathology of the elbow joint, occurring relatively often and resulting in disability of children.The treatment of nonunion of the lateral humeral condyle of humerus with cubitus valgus remains controversial. Purpose of this report was improvement of the results of surgical treatment of the nonunion of the lateral humeral condyle of humerus with cubitus valgus of the lateral humeral condyle of humerus with cubitus valgus with use of differential approach to the surgical strategy.Material and methods. We were observing 28 children (17 boys and 11 girls) with nonunion and long-standing nonunion of lateral condyle of humerus, with various degrees of severity. There were used MRI and X-ray investigations for differential study of the patients divided into 3 groups in relation to stability and non-stability of the nonunion of the lateral humeral condyle of humerus with cubitus valgus of the lateral humeral condyle of humerus with cubitus valgus.Results. All 28 patients lateral humeral condyle nonunions with cubitus valgus achieved union within sixty five days after operative procedure using Ilisarov’s technique. The mean postoperative humerus-ulna angle was 6,0 degrees of cubitus valgus. All of reverse T-osteothomies healed uneventfully, and there was no loss of correction postoperatively.  The mean duration of follow-up was 7 years. The overall results were excellent in 15(53,5%) patients,  good in 11(39,3%) patients, and fair in 2(7,2%) patients.

CONTEXT: Colonic carcinoids, excluding those arising in the appendix, have proved to be extremely rare. Due to their rarity, the characteristics and behavior of this unusual malignancy remain unclear. OBJECTIVE: To review the clinicopathologic features of patients operated on carcinoid tumors of the colon. METHODS: Twenty-three patients (12 males and 11 females) were operated on colonic carcinoids. The mean age of the patients was 63.0 ± 12.9 years (42 to 85 years). The clinical and histopathological data of patients who were pathologically diagnosed as having carcinoid tumors and submitted to surgical treatment over a 30-year period (1977-2007) were gathered. Actuarial patient survival was estimated using the Kaplan-Meier method, with carcinoid-specific death as the outcome. RESULTS: The mean time elapsed between onset of symptoms and surgical treatment was 8.3 months (1.5 to 20 months). The most frequent symptoms or signs encountered were abdominal pain followed by anorexia or weight loss, diarrhea, abdominal tenderness, palpable abdominal mass, and rectal bleeding. No carcinoid syndrome was noted. The lesion was located in the cecum in 16 (69.6%) patients, in the sigmoid in 3 patients (13.0%), in the ascending colon in 3 patients (13.0%), and in the transverse colon in one patient (4.3%). Twenty-one (91.3%) patients were operated on curative intent. Spreading of the disease to the liver and peritoneum was found in two (8.7%) patients who submitted to intestinal bypass. The mean size of the largest mass was 3.7 ± 1.2 cm (1.5 to 6.2 cm). There were multiple (two or more) lesions in three cases (13.0%). In the resected cases, the lymph nodes were compromised in 10 patients (47.6%) and disease-free in 11 (52.4%). Venous invasion and neural infiltration were both present in five (23.8%) patients. The tumors had penetrated the muscularis propria in all resected cases. Four (17.4%) patients had a second non-carcinoid primary tumor. Three (13.0%) patients died due to postoperative complications and five (21.7%) patients died from metachronous metastases or local recurrence. Fifteen patients (65.2%) remain alive without evidence of active disease. The mean follow-up period was 12 years (1.2 to 18 years), whereas the mean global survival was 50.7 ± 34.2 months and the crude survival rate at 5 years was 62.7%. CONCLUSIONS: Carcinoid tumors of the colon are frequently right-sided and may be clinically occult until an advanced stage is reached. Based on the relatively poor survival rates reported, it is recommended that, in addition to standard surgical resection, vigorous surveillance for metastatic disease must be performed, particularly during the first 2 years after surgery. In addition, these patients require evaluation of the entire gastrointestinal tract for evidence of coexisting malignancy, along with an extended period of follow-up, because tumor recurrences after 5 years are not uncommon.

Background: Bronchiectasis is usually caused by pulmonary infections and bronchial obstructions. It is still a serious problem in developing countries, as our country. We reviewed the morbidity and mortal-ity rates and outcomes of bronchiectasis surgical treatment. Patients and methods: Between years 2000 and 2016, one hundred and seven (107) patients, sixty nine (69) of whom female and thirty eight (38) male underwent pulmonary resection for bronchiecta-sis. The mean age was 35years (range, 13–66 years). Mean duration of symptoms was 12 years. Results: Symptoms were copious amount of purulent sputum in 84 patients, expectoration of foul-smelling sputum in 72, haemoptysis in 21 and cough in all patients. The indications for pulmonary resection were: medical therapy failure in eighty two (82) patients, massive haemoptysis in eighteen and lung abscess in seven (7) patients. The disease was bilateral in twenty seven (27) patients and mainly confined in the lower lobe. Eighty six (86) patients had a lobectomy, 7 had a segmentectomy, two patients right pneumonectomy. Operative morbidity was seen in 47 patients (43.9 %) and mor-tality in two (2) patients. Follow-up was complete in 97 patients with a mean of 5 years. Overall, 78 patients were asymptomatic after surgical treatment; symptoms were improved in 24, and unchanged or worse in 5. Conclusions: Surgical treatment of bronchiectasis is more effective in patient with localized disease. It is satisfactory with acceptable ratio of morbidity and mortality.

Abstract PurposeThe present study aimed to explore the influence of ulnar bow on the surgical treatment of Bado type I missed Monteggia fracture in children.MethodsThis study is a retrospective review of 24 patients between November 2010 and March 2019. All patients were treated with open reduction of the radial head and ulnar opening wedge osteotomy without annular ligament reconstruction. The mean interval between injury onset and surgery was five months (range: 2–12 months). The average age of participants at the time of surgery was 6.4 years (range: 3–10 years). We evaluated the maximum ulnar bow (MUB) and MUB position (P-MUB) via radiography. The patients were divided into middle group (group A: 14 cases, MUB located at 40% to 60% of the distal ulna) and distal group (group B: 10 cases, MUB located at 20% to 40% from the distal end of the ulna) based on P-MUB. The mean period of follow-up was 37 months (range: 6–102 months).ResultsAt the last follow-up, all the children showed stable reduction of the radial head, and the flexion function of elbow joint improved after operation (P<0.05). Group A presented a larger the ratio of maximum ulnar bow(R-MUB) and angle of ulnar osteotomy(OA) than group B (P<0.05). There was statistically significant difference between group A and Group B in the P-MUB (P < 0.05). The osteotomy angle was positively correlated with the R-MUB (R2 =0.497,P=0.013), The osteotomy angle was positively correlated with the P-MUB (R2=0.731,P=0.000), The R-MUB is proportional to the P-MUB (R2 =0.597,P=0.002). The regression equation of P-MUB and osteotomy angle: Angle=7.064+33.227* P-MUB (R2=0.459, P =0.000).ConclusionWhen the ulnar bow is positioned at the middle ulna, a stable reduction of radial head need to be achieved through a larger angle in the ulnar osteotomy. If the position of maximum ulnar bow (P-MUB) is closer to the middle of the ulna or the ratio of maximum ulnar bow (R-MUB) is larger, the osteotomy angle is larger.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Aims This study aimed to evaluate the incidence and prognosis of patients with spinal metastasis as the initial manifestation of malignancy (SM-IMM). Patients and Methods We retrospectively reviewed the electronic medical records of 338 patients who underwent surgical treatment for metastatic spinal disease. The enrolled patients were divided into two groups. The SM-IMM group included patients with no history of malignancy whose site of primary malignancy was diagnosed after the identification of spinal metastasis. The other group included patients with a history of treatment for primary malignancy who then developed spinal metastasis (SM-DTM). The incidence of SM-IMM by site of primary malignancy was calculated. The difference between prognoses after surgical treatment for SM-IMM and SM-DTM was established. Results The median follow-up period was 11.5 months (interquartile range (IQR) 3.2 to 13.4) after surgical treatment. During the follow-up period, 264 patients died; 74 patients survived. The SM-IMM group consisted of 94 patients (27.8%). The site of primary malignancy in the SM-IMM group was lung in 35/103 patients (34.0%), liver in 8/45 patients (17.8%), kidney in 10/33 patients (30.3%), colorectum in 3/29 patients (10.3%), breast in 3/22 patients (13.6%), prostate in 3/10 patients (30%), thyroid in 4/8 patients (50%), and ‘other’ in 28/88 patients (31.8%). On Kaplan–Meier survival analysis, the SM-IMM group showed a significantly longer survival than the SM-DTM group (p = 0.013). The mean survival time was 23.0 months (95% confidence interval (CI) 15.5 to 30.5) in the SM-IMM group and 15.5 months (95% CI 11.8 to 19.2) in the SM-DTM group. Conclusion Of the 338 enrolled patients who underwent surgical treatment for spinal metastasis, 94 patients (27.8%) underwent surgical treatment for SM-IMM. The SM-IMM group had an acceptable prognosis with surgical treatment. Cite this article: Bone Joint J 2019;101-B:1379–1384.

Object The goal of this report was to describe the safety and effectiveness of nucleus ventralis intermedius (VIM) thalamotomy performed with the Leksell Gamma Knife (GK) for the treatment of essential tremor (ET). Methods One hundred seventy-two patients underwent a total of 214 VIM thalamotomy procedures with the Leksell GK between February 1994 and March 2007 for treatment of disabling ET. Eleven patients were lost to follow-up less than 1 year after the procedures, so that in this report the authors describe the results in 161 patients who underwent a total of 203 thalamotomies (119 unilateral and 42 bilateral). Results There were statistically significant decreases (p < 0.0001) in tremor scores for both writing and drawing. The mean postoperative follow-up duration for all patients was 44 ± 33 months. Fifty-four patients have been followed for more than 60 months posttreatment. There were 14 patients who suffered neurological side effects that were temporary (6) or permanent (8), which accounted for 6.9% of the 203 treatments. All complications were related to lesions that grew larger than expected. Conclusions A VIM thalamotomy with the Leksell GK offers a safe and effective alternative for surgical treatment of ET. It is particularly applicable to patients who are not ideal candidates for deep brain stimulation but can be offered to all patients who are considering surgical intervention for ET.

Abstract BACKGROUND: Brainstem cavernous malformations (BSCMs) are relatively uncommon, low-flow vascular lesions. Because of their relative rarity, relatively little data on their natural history and on the efficacy and durability of their treatment. OBJECTIVE: To evaluate the long-term durability of surgical treatment of BSCMs and to document patient outcomes and clinical complications. METHODS: The charts of all patients undergoing surgical treatment of BSCM between 1985 and 2009 were reviewed retrospectively. The study population consisted of 300 patients who had surgery for BSCM. Forty patients were under 19 years of age at surgery; pediatric BSCMs have been reported separately. Patient demographics, lesion characteristics, surgical approaches, and patient outcomes were examined. RESULTS: The study population consisted of 260 adult patients with a female-to-male ratio of 1.5 and mean age of 41.8 years. Of the 260 patients, 252 presented with a clinical or radiographic history of hemorrhage. The mean follow-up in 240 patients was 51 months. The mean Glasgow Outcome Scale on admission, at discharge, and at last follow-up was 4.4, 4.2, and 4.6. Postoperatively, 137 patients (53%) developed new or worsening neurological symptoms. Permanent new deficits remained in 93 patients 3(36%). There were perioperative complications in 74 patients (28%); tracheostomy, feeding tube placement, and cerebrospinal fluid leakage were most common. Eighteen patients (6.9%) experienced 20 rehemorrhages. Twelve patients required reoperation for residual/recurrent BSCM. The overall annual risk of postoperative rehemorrhage was 2%/patient. CONCLUSION: Although BSCM surgery has significant associated risks, including perioperative complications, new neurological deficits, and death, most patients have favorable outcomes. Overall, surgery markedly improved the risk of rehemorrhage and related symptoms and should be considered in patients with accessible lesions.

Background: Cervical spondylotic myelopathy increases with age, but not all cases are symptomatic. It is usually diagnosed clinically and radiologically (X-ray and magnetic resonance imaging). Surgical treatment is indicated in severe symptomatic cases, while treatment controversy exists in the presence of less severe cases. Anterior and posterior approaches are generally used for decompression with no significant differences in the results of both. Methods: A total of 287 patients of cervical spondylotic myelopathy were treated at our hospital between January 2004 and December 2015. Only 140 patients were eligible for our study. They had at least 5 years of follow-up using full clinical scores and radiological evaluation. They were divided into two groups: group I with 73 patients (aged 23–79 years) underwent posterior decompression, lateral mass instrumentation, and fusion, while group II with 67 patients (aged 33–70 years) underwent anterior decompression, instrumentation, and fusion. Neck Disability Index, local score, and X-ray were used in the evaluation of the patients. Results: Preoperative mean ± standard deviation of Neck Disability Index of both the groups was 32.06 ± 6.33 and 29.88 ± 5.48, which improved in the last visit (>5 years) to 5.81 ± 7.39 and 2.94 ± 5.48 for groups I and II, respectively (p value <0.05). The local score of groups I and II was (P = 1, F = 21, G = 31, E = 19) and (P = 1, F = 12, G = 36, E = 18), which on discharge day improved to (P = 1, F = 4, G = 12, E = 55) and (P = 0, F = 3, G = 6, E = 58) at last follow-up, respectively. Fusion rate was nearly equal for both the groups during all the follow-up intervals and it was 91.1% and 91.7% in the last follow-up. Conclusion: There were no significant differences in the clinical and radiological results between the anterior and posterior approaches used in the surgical treatment of spondylotic cervical myelopathy. However, statistically significant results of Neck Disability Index of anterior approach were not clinically important and may be due to changes in the size and shape of the neck in group II.

Object Because the main pathology of cervical spondylotic myelopathy (CSM) is spinal cord damage due to compression, surgical treatment is usually recommended to improve patient symptoms and prevent exacerbation. However, lack of clarity of prognosis in cases that present with insignificant symptoms, particularly those of mild CSM, lead one to question the veracity of this course of action. The purpose of this study was to elucidate the prognosis of mild CSM without surgical intervention by evaluation of clinical symptoms and MR imaging findings. Methods Sixty cases of mild CSM (42 males and 18 females, average age 57.2 years) presenting with scores of 13 or higher on the Japanese Orthopaedic Association (JOA) scale were treated initially by in-bed Good Samaritan cervical traction without surgery. These patients were enrolled between 1995 and 2003 and followed up periodically until the date of myelopathy deterioration or until the end of March 2009. The deterioration of myelopathy was defined as a decline in JOA score to less than 13 with a decrease of at least 2 points. As a prognostic factor, the authors used their classification of spinal cord shapes at their lateral sides on axial T1-weighted MR imaging. “Ovoid deformity” was classified as a situation in which both sides were round and convex, and “angular-edged deformity” where one or both sides exhibited an acute-angled lateral corner. The duration of follow-up was assessed as the tolerance rate of mild CSM using Kaplan-Meier survival analysis and compared between 2 groups classified by MR imaging findings. Furthermore, differences between groups were analyzed by various applications of the log-rank test. Results Of the initial 60 cases, follow-up records existed for 55, giving a follow-up rate of 91.7% (38 males and 17 females, average age 56.1 years). The mean JOA score at end point was 14.1, which was not statistically different from the mean of 14.5 at the initial visit. Deterioration in myelopathy was observed in 14 (25.5%) of 55 cases, whereas 41 (74.5%) of 55 cases maintained mild extent myelopathy without deterioration through the follow-up period (mean 94.3 months). The total tolerance rate of mild CSM was 70%. However, there was a significant difference in the tolerance rate between the cases with angular-edged deformity (58%) and cases with ovoid deformity (95%; p = 0.049). Conclusions The tolerance rate of mild CSM was 70% in this study, which proved that the prognosis of mild CSM without surgical treatment was relatively good. However, the tolerance rate of the cases with angular-edged deformity was 58%. Therefore, surgical treatment should be considered when mild CSM cases show angular-edged deformity on axial MR imaging, even if patients lack significant symptoms.
