[Are computer assisted total knee replacements more accurately placed? A meta-analysis of comparative studies].

Computer-assisted surgery (CAS) has become established in many hospitals throughout the world, especially in the form of computer navigation for total knee replacement (TKR). Analysis of the studies available revealed 18 comparative studies examining the precision of implantation of knee endoprostheses following CAS and after implantation by the conventional technique. In a meta-analysis of 13 studies in which the same safe zone of +/-3 from neutral alignment was defined for the leg axis, a total of 1,784 TKR were performed. In the group of patients in whom the conventional technique was used, 75.6% (654/865) of TKR were implanted within the safe zone. In the CAS group 93.9% (863/919) of the prostheses were implanted within the safe zone (p<0.0001). The differences between the groups were statistically significant in 11 of the 13 studies, and the difference between groups for the entire patient population is highly significant. Only limited clinical results were ascertained in these comparative studies; there were no great differences between the treatment groups in clinical course.

[Postoperative pain relief is an important factor for the patients' selection of a clinic. Results of an anonymous survey].

AIM: The aim of the survey was to elucidate the significance of postoperative pain therapy for the patient and its influence on the choice of hospital. METHODS: This prospective, anonymous survey of consecutive patients in a general surgical clinic was performed by an independent study nurse. RESULTS: A total of 161 patients were included; 90% of the surgical patients considered "good pain therapy" as a highly important factor, and three of four patients would admit themselves more likely to a clinic well known for "good pain therapy." If the patients could choose their hospital, factors such as "medical care by the physicians" are most important (rank 1; rank 1 most important, rank 10 most unimportant) followed by quality of "nursing care" (mean rank 2.6) and "good pain therapy" (mean rank 3.6). Older patients (> or = 60 years) preferred a hospital with known "good pain therapy" more often for surgical therapy than younger patients (< 60 years). CONCLUSION: It can be concluded that postoperative pain relief is an important factor for the patients' selection of a clinic and is influenced by an age of > or = 60 years.

The Langerhans' cell histiocytosis (eosinophilic granuloma) of the cervical spine: a rare diagnosis of cervical pain.

We present the case of a 44-year-old man who complained of cervical pain. He was treated with physiotherapy and analgetics. Because of persistent pain, computed tomography (CT) scan and MRI were performed. They revealed an osteolytic destruction of the fourth cervical vertebra. The patient was treated surgically for removal of the tumor and stabilization of his cervical spine. Histology of the osteolytic material led to the diagnosis of an eosinophilic granuloma of the cervical spine. This case report describes the incidence, clinical significance, background and therapy of an eosinophilic granuloma of the spine.

[Surgical pain management. A Germany-wide survey including the effect of clinical guidelines].

INTRODUCTION: Over the last few years, various studies have aimed at improving the diagnosis and therapy of perioperative and posttraumatic pain. METHODS: In an anonymous postal survey, 2,393 German surgical clinics were asked to describe several aspects of their clinical pain treatment. In order to assess the influence of interdisciplinary guidelines on surgical pain therapy, the results of this survey were compared to a survey from 1997. RESULTS: The response rate was 30.8% ( n=738). Pain was measured quantitatively in 11.4% ( n=80) of hospitals, a figure which is unchanged since 1997. In pain treatment,however, some changes were discernible: while 46.6% of all hospitals in 1997 used patient-controlled analgesia often or occasionally, this proportion has risen to 64.5%.Both, the national acute pain guidelines and the WHO chronic pain guidelines were well known (71.3% and 74.7%) and accepted (98.8% and 98.5%, respectively). Among those surgeons who knew the national guidelines,93.7% reported that they used them clinically. In 149 hospitals (20.2%), local guidelines have been developed either anew or from existing guidelines. CONCLUSIONS: Although clinical guidelines are widely used, pain therapy in surgical patients has improved only marginally.

[What prognostic factors correlate with activities of daily living (Barthel Index) 1 year after para-articular hip fracture? A prospective observational study].

UNLABELLED: The aim of this prospective study was to identify prognostic factors predicting post-operative outcome in patients one year after their hip fracture. METHODS: From October 1996 until September 1997 all patients (n = 98) treated for a hip fracture in our hospital were prospectively included into the study. Follow up was performed at three, six and twelve months after the injury. The main outcome variable was the activity of daily living measured by the Barthel-Index. An univariate analysis of the variables age, gender, ASA-classification, type of fracture and treatment, length of stay and rehabilitation was performed and all these variables were correlated with the Barthel-Index. A multiple logistic regression was performed for identification of prognostic factors predicting outcome. RESULTS: The one year lethality was 33% (n = 31). All patients younger than 75 years reached their preoperative activity level at one year follow up. Patients with age of 75 years or more experienced a reduction of their activities of daily living of 20%. The ADL-differences of both groups at the follow up after 3, 6 and 12 months showed a significant p-value (p < 0.001). The ADL-differences between the group of patients with or without a transfer to a specialized rehabilitation center were not significant. The multivariate analysis showed that the preoperative use of the Barthel-Index was the best prognostic factor for outcome until one year after the injury. CONCLUSION: The preoperative Barthel-Index should be seriously considered for therapeutic decision making in patients with hip fractures.

[Postoperative nausea and vomiting (PONV). Clinical significance, basic principles, prevention and therapy].

INTRODUCTION: The incidence of postoperative nausea and vomiting (PONV) of in- and outpatient surgical patients is about 30% (range 2-45%). METHODS: Based on etiology, anatomy and physiology, this review article provides a critical evaluation of the present PONV literature with the aim of outlining current prophylaxis and treatment strategies. RESULTS: PONV is often associated with postoperative pain and its treatment. Patients are often more compromised by PONV than by postoperative pain. Surveys demonstrate that 78% of the surgeons consider PONV to be a relevant problem in clinical practice; 82% argue for better management of PONV. However, only 28% of the general surgical patients with PONV received sufficient antiemetic therapy. Studies demonstrate that the prophylactic use of antiemetics in patients at risk can lead to complete symptom control in 85% of the cases. Combination therapy of different antiemetic strategies can further increase the rate up to 96%. CONCLUSION: There is a need for surgeons to pay more attention to patient-related symptoms.

[Therapeutic concept for preventing chronic phantom pain after traumatic brachial plexus lesion].

We report on a 29-year-old motorcyclist, who had suffered a traumatic right side arm plexus lesion. The myelo-CT image showed a avulsion of the cervical roots C7/C8. Five days after the accident the patient complained of phantom pain in the right plegic arm and was presented to our acute pain service (APS). The patient complained of lancinating attacks of severe phantom pain in the right arm (visual analogue scale intensity of 80-100 pts.). The initial pain treatment was performed with PCA (piritramide), and because of the lancinating pain character carbamazepine treatment was introduced. The pain intensity increased under carbamazepine (VAS = 100 pts.), and after treatment with five cycles of salmon-calcitonin infusion the pain intensity decreased (VAS = 10 pts). After withdrawal of the infusion therapy with salmon calcitonin the pain intensity increased up to VAS = 70 pts. TENS therapy five times per day showed no analgetic effect. We repeated the calcitonin-infusion therapy and after five i.v. cycles we continued with 200 I.U. salmon calcitonin intranasal per day. The initial phantompain intensity decreased (VAS = 40 pts.), but showed no long term analgesia. The additional psychological treatment with relaxation techniques (Jacobson/Bensen) showed the desired phantom pain relief. An interdisciplinary and multimodal cooperation between anesthesiologists, trauma surgeons, neurosurgeons and psychologists is needed for successful phantom pain treatment after traumatic brachial plexus lesion. Intravenous salmon calcitonin showed only short-term analgetic effect.

[Therapy of phantom pain with salmon calcitonin and effect on postoperative patient satisfaction].

In this prospective clinical study we examined the intravenous application of salmon-calcitonin in eight patients with severe phantom limb pain (Visual Analogue Scale = 50-100). The patients presented at the Acute Pain Service (APS) section of the Second Department of Surgery, University of Cologne. Six of eight patients (75%) had no phantom limb pain after 10 days of intravenous treatment with salmon-calcitonin (maximum of five cycles of calcitonin infusion). Systematic follow-up examinations after 3, 6 and 12 months showed long-term success. Patient satisfaction was examined with a numeric rating scale (NRS 1-6) between the single infusion cycles. When patient satisfaction was low, the physician modified the time period or drug dosage between infusions. This study shows good or excellent results in patient satisfaction for six of eight patients (75%). A prospective randomized trial is required to verify the excellent results of intravenous salmon-calcitonin in a larger population. Alternative pharmacological and operative treatments of phantom limb pain are critically reviewed and assessed.
