The experience of diagnosis and surgical treatment of spine osteoid osteoma and osteoblastoma in 60 patients was presented. In 78% of cases osteoid osteoma was diagnosed before operation, in 36% of cases by X-ray examination, and in 86 % of all patients examined by CT method. Osteoblastoma was diagnosed by clinical examination in 8% of cases, and by CT method in 80% of the examined patients. By morphologic criteria noninvasive osteoblastoma (osteoid osteoma) 33 observations, invasive one 23 observations, malignant (agressive) 2 observations, multifocal one 2 observations were differentiated. The conclusion was drawn that there were various types of single pathologic process, i.e. osteoblastoma. Surgical treatment tumor resection together with surrounding zone of sclerosis, gave the recovery in 95% of cases. Three patients with tumor recurrence refused reoperation, their outcomes were unknown.

Modular Endoprosthesis

The major method of malignant bone tumors treatment is surgery. The most important task of an orthopedic surgeon is to preserve an adjacent joint. Currently, there are a large number of various reconstructive surgeries, including structural bone allograft, allocomposite and modular endoprosthetics replacement. The aim: to analyze the results of surgical treatment for proximal tibia malignant tumors using modular endoprosthesis. Materials and methods. The results of proximal tibia (PT) modular endoprosthetic replacement in 48 patients with PT tumor lesions were evaluated. The patients were divided into two groups: I (n = 36) – tumor resection and primary modular endoprosthesis, II (n = 12) – revision modular endoprosthetic replacement due to complications. Complications were divided into oncological, mechanical and non-mechanical. The functional outcomes were measured using the MSTS and TESS scores. Results. During the treatment, 10 (21.2 %) patients underwent myofascioplastic amputation at the middle third of the thigh: due to periprosthetic infection – 8 people and tumor recurrence – 2. It was found that the patients got back to regular way of life on average in 2.0–2.5 months. Functional results on the MSTS score were 73 ± 12 %, on the TESS score – 74 ± 16 %, which corresponds to good functional results. Among the patients, who underwent limb salvage surgery, no tumor recurrence was detected during a follow-up period from 6 months up to 11 years. Conclusions. The choice of surgical treatment depends on the size of tumor, its location, pathohistomorphological picture, age, presence of pathological fractures, vascular and nerve tumor invasion. The use of modern designs of PT modular tumor endoprostheses and perfect surgeries makes it possible to minimize complications.

Experience in diagnosis and treatment of benign pelvic tumors and tumor-like diseases in children was summarized. There were 104 patients, aged 2-18 years. Complex diagnosis included modern radiologic methods (CT, MRT, angiography). The treatment was performed taking into account the nosologic form and pathologic process volume. Vast resections of pelvic bones were performed in osteochondroma, fibrous dysplasia, chondromyxoid fibroma, solid form of aneurismal cyst as well as in aneurismal cysts in cases of failed paracentetic treatment. In tumors of small sized (osteoid-osteoma, osteoblastoma) surgical treatment was performed with computer navigation. Paracentetic treatment was applied in aneurismal cysts, eosinophilic granulema of bone as well as in residual cavities after failed previous interventions. In patients with aggressive aneurismal cysts roentgenendovascular embolization of pathologic vessels in combination with paracentetic treatment or endoscopic intervention were used. Follow-up ranged from 1 to 8 years. Recurrences were noted in 3 (6.4%) patients with aneurismal cyst.

Late Stages

SummaryThe treatment of femoral head necrosis of adults is still rather problematic. Conservative treatment has been reported relatively unsuccessful and surgical treatment does not show convincing results either. The most effective seems to be a surgical treatment in early stages of the disease, however, the diagnosis still remains relatively complicated. For the late stages (2B and above) the most effective treatment option is represented by core decompression and vascular grafting. However, drilling and plombage (especially when using press-fit technique) seems to be successful, although not excellent. The authors describe their own method of drilling and plombage of the necrotic zone of the femoral head in 41 patients with X-ray detected necrotic changes of the femoral head. The pain measured by VAS was seen to decrease after surgery in all patients significantly. The Jacobs score was also observed to have increased (from fair to good outcome). We have not observed any large femoral head collapse after surgery, moreover, in some cases an improvement of the round shape of the femoral head was seen. It is important to mention that in all cases femoral heads with existing necrotic changes (flattening or collapse) were treated. Although the clinical improvement after surgery was not significantly high, the method we describe is a safe and simple method of diminishing pain in attempt to prepare the femoral head for further treatment in a future, without significant restriction of the indication due to necrosis (osteochondroplasty, resurfacing, THR).

Circulating Levels

Tumor resection represents the only curative treatment option for patients with biliary tract cancers (BTCs), including intrahepatic cholangiocarcinoma (CCA), perihilar and extrahepatic CCA and gallbladder cancer. However, many patients develop early tumor recurrence and are unlikely to benefit from surgery. Therefore, markers to identify ideal surgical candidates are urgently needed. Circulating programmed cell death 1 ligand 1 (PD-L1) has recently been associated with different malignancies, including pancreatic cancer which closely resembles BTC in terms of patients’ prognosis and tumor biology. Here, we aim at evaluating a potential role of circulating PD-L1 as a novel biomarker for resectable BTC. Methods: Serum levels of PD-L1 were analyzed by ELISA in 73 BTC patients and 42 healthy controls. Results: Circulating levels of preoperative PD-L1 were significantly lower in patients with BTC compared to controls. Patients with low PD-L1 levels displayed a strong trend towards an impaired prognosis, and circulating PD-L1 was negatively correlated with experimental markers of promalignant tumor characteristics such as CCL1, CCL21, CCL25 and CCL26. For 37 out of 73 patients, postoperative PD-L1 levels were available. Interestingly, after tumor resection, circulating PD-L1 raised to almost normal levels. Notably, patients with further decreasing PD-L1 concentrations after surgery showed a trend towards an impaired postoperative outcome. Conclusion: Circulating PD-L1 levels were decreased in patients with resectable BTC. Lack of normalization of PD-L1 levels after surgery might identify patients at high risk for tumor recurrence or adverse outcome.

Abstract Background:To describe the preliminary suppressive effects of iodine 125 brachytherapy for malignant lacrimal gland tumors after excisionMethods:The study recruit 9 patients with lacrimal gland carcinoma from May 2017 to December 2020. All patients underwent eye sparing surgical tumor resection first and then received iodine 125 interstitial brachytherapy to prevent tumor recurrence. We look over whether tumor recurred or metastasized by detecting the visual function and CT/MRI/PET MRI of every patient.Results1 patient was lost visit. The median follow up period was 29 months of other 8 patients (range, 7 43 months). One patient experienced recurrence two years later but was free from local disease after iodine 125 seeds were implanted one more time. The vision of one female patient was lost due to the seeds moving to the optic nerve. In the remaining 6 patients the vision was no changed, and CT/MRI showed no tumor was recurrencedConclusions:Permanent iodine 125 strip implantation in the orbit can be used as an alternative eye sparing surgery for malignant lacrimal gland tumors after tumor excision. It can control tumor recurrence and maintenance of vision and good cosmesis.

Introduction: The aim of our study was to evaluate the interest of ultrasound in the exploration of painful shoulders evoking rotator cuff lesions and to determine the diagnostic value of the different tendon tests through a confrontation physical examination versus shoulder ultrasound. Materials and methods: A prospective study was conducted including patients consulting for shoulder pain that suggests a rotator cuff lesion. All patients underwent a clinical examination, an x ray and shoulder ultrasound.Results: The confrontation physical examination versus shoulder ultrasound showed that Jobe's test is very sensitive (100%) but less specific (27%), the Patte test, has a high sensitivity (100%) but an average specificity (51%), the Palm-Up test was fairly sensitive (91%) but not very specific (43%) and the Gerber test was more specific (95.7%) and less sensitive (38%). The comparison between x ray and ultrasound showed that ultrasound of shoulder is more efficient in the detection of calcifications and erosions of humeral head.Conclusion: Ultrasound of shoulder is more performant than physical examination and x ray in exploring the rotator cuff lesions.

The aim of this study was to report the outcome of the use of an external fixator to treat a pelvic canal stenosis in a 5-month-old female cat. The cat was referred with a history of 3 weeks of intermittent signs of constipation refractory to the medical management, occurring after surgical treatment for a bilateral sacroiliac luxation and sacral fracture. The clinical examination revealed instability of the pelvis and a radiograph showed a pelvic canal stenosis and megacolon. External fixator was the method of choice to be used in this case. The manually applied tension on an external fixator resulted in a widening of the pelvic canal. At 45 days after surgery, there were no signs of constipation, and the radiological examination showed progressive bone healing. At 18 months post-op, the cat had no abnormalities both on the clinical examination and on the radiography. In conclusion, the use of an external fixator led to the widening of the pelvic canal using a minimally invasive procedure. To the authors’ knowledge, this case report represents the first surgical description and clinical outcome of the widening of the pelvic canal in cats using an external skeletal fixator.

Objective. To analyze safety and efficacy of X-ray surgical treatment of choledocholithiasis in case of failed endoscopic procedures. Material and methods. A retrospective analysis included 195 patients with choledocholithiasis who underwent X-ray surgical treatment. Primary X-ray surgical intervention was antegrade cholangiostomy. Data of antegrade cholangiography were used to determine type of endobiliary intervention. Antegrade mechanical and pneumatic choledocholithotripsy and lithoextraction, balloon dislocation of stones of the common bile duct into duodenum or jejunum, lithoextraction using rendezvous technique after endoscopic papillotomy through transpapillary drainage tube or a wire were applied. Results. Puncture and drainage of non-dilated bile ducts were successfully performed in 30 (15.4%) patients. There were 212 procedires of cholangiostomy in 195 patients including redo interventions. Complications after cholangiostomy were absent in 92.9% of cases. Minor complications occurred in 7.1% of cases. Antegrade mechanical and pneumatic choledocholithotripsy and lithoextraction was performed in 118 (98.3%) patients. Balloon dislocation of stones of the common bile duct into duodenum was applied in 52 (81.3%) patients. Lithoextraction using rendezvous technique after previous endoscopic papillosphincterotomy was performed in 12 (60%) patients. Six patients underwent transpapillary external-internal drainage of common bile duct. Five patients had stricture of biliodigestive anastomosis complicated by cholelithiasis. Lithotripsy and lithoextraction through antegrade approach or dislocation of stones into jejunum after previous balloon dilatation were performed in these patients. Postoperative mortality was 1.5%. Minimally invasive techniques were absolutely effective for choledocholithiasis in 187 (98.9%) patients. Conclusion. Antegrade X-ray surgical management is effective and safe in patients with choledocholithiasis and unsuccessful previous endoscopic procedures. Integral efficiency of antegrade management of cholelithiasis was 88.8%.
