Percutaneous vertebroplasty has become an efficient technique for the treatment of painful vertebral fractures. Osteoporotic vertebral compression fractures are characterized by severe back pain and immobilization causing other complications like thrombosis or pneumonia. Vertebral cement augmentation provides increased strength of the vertebral body and an obvious pain relief. Between 1989 and 2004, 30 studies and a total of 2,086 treated patients have been published in literature. A review of these studies has been performed. The number and age of the patients, number of treated vertebrae, pre- and postoperative outcome of pain and complications of the different studies were assessed and analyzed. Percutaneous vertebroplasty is an efficient technique with low complication rates and a significant reduction in pain. It rapidly improves the mobility and quality of life of patients with vertebral compression fractures. With an increasing number of treated patients, experience with this interventional technique has become excellent. But still there are no randomized controlled trials available, showing that percutaneous vertebroplasty has a significantly better outcome than other treatment options, especially after a long-term follow-up.
Background and purpose The diagnosis and treatment of isolated greater tuberosity fractures of the proximal humerus is not clear-cut. We retrospectively assessed the clinical and radiographic outcome of isolated greater tuberosity fractures.Patients and methods 30 patients (mean age 58 (26–85) years, 19 women) with 30 closed isolated greater tuberosity fractures were reassessed after an average follow-up time of 3 years with DASH score and Constant score. Radiographic outcome was assessed on standard plain radiographs.Results 14 of 17 patients with undisplaced or slightly displaced fractures (≤ 5 mm) were treated nonoperatively and had good clinical outcome (mean DASH score of 13, mean Constant score of 71). 8 patients with moderately displaced fractures (6–10 mm) were either treated nonoperatively (n = 4) or operatively (n = 4), with good functional results (mean DASH score of 10, mean Constant score of 72). 5 patients with major displaced fractures (> 10 mm) were all operated with good clinical results (mean DASH score of 14, mean Constant score of 69). The most common discomfort at the follow-up was an impingement syndrome of the shoulder, which occurred in both nonoperatively treated patients (n = 3) and operatively treated patients (n = 4). Only 1 nonoperatively treated patient developed a non-union. By radiography, all other fractures healed.Interpretation We found that minor to moderately displaced greater tuberosity fractures may be treated successfully without surgery.
We report a 75-year-old male patient with an aneurysm of the left femoral artery after cemented total hip arthroplasty. Two months after the operation, the patient showed a spherical resistance and pain in the left groin. Examination showed a big false aneurysm of the left femoral artery. After resection of the aneurysm, an endovascular stent graft vessel prosthesis was implanted. The aneurysm originated from a punctual lesion of the artery caused by a screw. Since the first description of vessel lesions in orthopaedic surgery in 1964, a total of 24 cases of aneurysm in hip surgery have been described. Therefore, a review of literature tries to explain causes and mechanisms of vessel injuries in hip surgery and the possibilities of repair.
Monostotic Wbrous dysplasia of the spine is a rare entity. Only 26 cases, of which 11 were located in the cervical spine, are to be found in the literature. We report a 56-year-old male patient with cervicobrachialgia of half year's duration. Radiographs showed a diVuse destruction of the vertebral body and the spinous process of C 4 . A biopsy of the spinous process conWrmed histopathologically a Wbrous dysplasia. Due to minor symptoms, no surgical treatment was performed or is planned unless in case of increasing pain, an acute instability or neurological symptoms.
The aim of the study was to evaluate the feasibility, safety and effectiveness of CT-guided and MR-thermometry-controlled laser-induced interstitial thermotherapy (LITT) in adrenal metastases. Nine patients (seven male, two female; average age 65.0 years; range 58.7-75.0 years) with nine unilateral adrenal metastases (mean diameter 4.3 cm) from primaries comprising colorectal carcinoma (n = 5), renal cell carcinoma (n = 1), oesophageal carcinoma (n = 1), carcinoid (n = 1), and hepatocellular carcinoma (n = 1) underwent CT-guided, MR-thermometry-controlled LITT using a 0.5 T MR unit. LITT was performed with an internally irrigated power laser application system with an Nd:YAG laser. A thermosensitive, fast low-angle shot 2D sequence was used for real-time monitoring. Follow-up studies were performed at 24 h and 3 months and, thereafter, at 6-month intervals (median 14 months). All patients tolerated the procedure well under local anaesthesia. No complications occurred. Average number of laser applicators per tumour: 1.9 (range 1-4); mean applied laser energy 33 kJ (range 15.3-94.6 kJ), mean diameter of the laser-induced coagulation necrosis 4.5 cm (range 2.5-7.5 cm). Complete ablation was achieved in seven lesions, verified by MR imaging; progression was detected in two lesions in the follow-up. The preliminary results suggest that CT-guided, MR-thermometry-controlled LITT is a safe, minimally invasive and promising procedure for treating adrenal metastases.
The use of neoadjuvant chemotherapy in resectable liver metastases induced significant remissions without increasing morbidity. The rate of severe complications and cases of no R0-resection in this study was 31 % and was with that significantly lower than 50 % (95 % CI 17.6 %-47.1 %). The risk to the patient is therefore acceptable when undergoing neoadjuvant treatment in a prospective intergroup trial.
The purpose of this study was to determine the efficacy and safety of CT-guided percutaneous vertebroplasty in the treatment of vertebral compression fractures. The primary objectives were pain reduction and bone-cement leakage during a long-term follow-up in patients with osteoporotic vertebral compression fractures. CT-guided percutaneous vertebroplasty was carried out in 61 patients (mean age 71.4 years; range 42-83; female ratio: 73.8%) with vertebral compression fractures. Treatment was carried out on an outpatient basis. Pain, bone-cement leakage and complications were monitored and recorded. The mean follow-up time was 19.8 months (range 3-52). Paired comparison procedures were used for the analysis of the results, which showed that all patients had a significant reduction of pain. The mean visual-analogue scale (VAS) before treatment was 8.8 points (range 6.5-9.8 points). The mean VAS score after treatment was significantly reduced to 2.6 points (range 1.5-4.1 points; p<0.01). No clinical or neurological complications were documented. Minor and asymptomatic bone-cement leakage was observed in 54% of the cases. Percutaneous vertebroplasty is an efficient and safe interventional procedure which rapidly improves the mobility and quality of life of patients with vertebral compression fractures. CT-guidance is a reasonable upgrade in the treatment procedure which reduces the amount of bone-cement leakage.
