[Modified percutaneous achillotentomy according to Hoke for minimally invasive treatment of pointed foot]. / Modifizierte perkutane Achillotenotomie nach Hoke zur minimal-invasiven Spitzfußbehandlung.

OBJECTIVE: Various underlying diseases can lead to a pointed foot in children and adults. If the gastrocnemius and soleus muscles are structurally shortened, various surgical procedures are available to correct this malposition. A preferred method for restoring a normal dorsiflexion of the upper ankle joint is percutaneous achillotentomy according to Hoke. Consideration of the physiological-anatomical torsion of the Achilles tendon as it corresponds to the White technique and is recommended by some authors shows in our experience no advantages. In the present work, we show a modified, likewise minimally invasive form of this surgical method with which immediate full weight-bearing of the affected lower extremity is possible from postoperative day 1. INDICATIONS: All clinically relevant structural pointed foot, for primary and/or for revision treatment. CONTRAINDICATIONS: Infection in the area of the operation. SURGICAL TECHNIQUE: No tourniquet, 3 incisions with the 15 mm knife: (1) medial distal at the transition from the Achilles tendon to the calcaneus, (2) medial proximal approximately 7 cm proximal to the 1st stab incision, (3) lateral, midway between the first two incisions; no skin suturing, application of a lower leg cast. POSTOPERATIVE MANAGEMENT: On postoperative day 1, cast hybridization using Scotchcast (3M Deutschland GmbH, Neuss, Germany), followed by pain-adapted full weight-bearing; removal of the cast in the outpatient department after 4 weeks. RESULTS: A total of 104 patients underwent surgery, 1 case of a local pressure point, no infections, no overcorrections, no Achilles tendon ruptures, in one case a postoperative relapse due to a broken cast. The risk of overcorrection to the foot, which was considered the main complication in the literature, did not occur in any of the cases.

Balloon-assisted sacroplasty as a successful procedure for osteoporotic sacral insufficiency fractures after failure of the conservative treatment.

Osteoporotic vertebral fractures without prior adequate traumatization are frequent diagnosed in orthopedics because of the increasing life expectancy and incidence of osteoporosis. The associated high mortality is caused by reduced mobilization which leads to a higher risk of infection and a bedridden state. On the other hand the diagnosis of sacral insufficiency fractures is often prolonged because of unspecific symptoms while being associated with similar risks. This article presents an overview of the present scientific literature and a retrospective analysis of patients treated via balloon-assisted sacroplasty. In 8 years, ten patients (three men and seven women) were treated. The average age was 78.4 years and the average time until the diagnosis 4.6 weeks. In most patients a significant pain reduction after the failure of conservative treatment thanks to operative treatment as well as increased mobility was observed. Only one experienced a minor surgical complication being cement leakage with nerval impaction which did not compromise her clinical outcome or satisfaction with the procedure. Balloon-assisted sacroplasty can possibly be seen as an effective symptomatic therapy in osteoporotic insufficiency fractures.

[Pain management in osteoporosis]. / Schmerztherapie bei Osteoporose.

Osteoporosis is a very common disease all over the world, in which a reduction in bone density can lead to an increased risk of fractures and a diminished physical height. Osteoporosis is also associated with acute and chronic pain, which especially occurs in the back and can significantly reduce the quality of life. To provide sufficient care for affected patients, it is essential to know the particularities of pain management in osteoporosis, such as pharmacological and nonpharmacological treatment options. This article gives a comprehensive review of pain management in osteoporosis and also explains the underlying pathomechanisms, risk factors, and diagnostic procedures.

Screening colonoscopy in HIV-infected patients: high rates of mucosal abnormalities in a German HIV-infected cohort.

OBJECTIVES: Because of the improved life expectancy provided by successful antiretroviral combination therapy, preventive health measures in HIV-infected patients have assumed increasing importance. To date, no data exist on rates of mucosal abnormalities detected by screening colonoscopy in > 50-year-old HIV-infected patients in Germany. The aim of this study was to obtain such data. METHODS: A screening colonoscopy was offered to 159 HIV-infected patients (age > 50 years) who presented for HIV standard of care visits at the infectious diseases out-patient clinic at the university hospital in Bonn over a 1-year period from February 2010. Pearson's χ(2) test, Fisher's exact test and the Mann-Whitney U-test were used for statistical analysis. RESULTS: Fifty-one patients (32.1%) had undergone a screening colonoscopy in the past 10 years, and 45 patients (28.3%) were eventually screened in the observation period. The median age of the 96 screened patients (86% male and 14% female) was 58 years [interquartile range (IQR) 54-64 years]. Overall, endoscopic abnormalities were found in 61% of patients. Histological examination showed tubular adenomas in 21.9% of patients, tubulovillous adenomas in 3.1% and serrated adenomas in 1%. Hyperplastic polyps were found in 15.6% of patients, a nonspecific colitis in 16.7% and diverticulosis in 12.5%. In four cases there was even an early-stage carcinoma (two anal, one rectal and one colon cancer). In univariate analysis, no significant differences with regard to immune status, highly active antiretroviral therapy, family history, personal risk factors or comedication were found between patients with dysplastic and normal mucosas. CONCLUSIONS: The high acceptance rate of screening colonoscopy and the in comparison with the HIV-negative population comparably higher rate of abnormalities in this cohort of HIV-infected patients justify enhanced implementation of screening colonoscopy in clinical practice.
