Stiffness is the most prevalent early local complication of primary total knee replacement, affecting approximately 6 to 7% of patients undergoing surgery. The definition of stiffness after total knee replacement in terms of restriction of the arc of motion has evolved in the last 2 decades as patients and physicians expect better postoperative functional outcomes. Gentle manipulation under anesthesia within 3 to 4 months of surgery improves the range of motion in most patients. However, approx ...

We read the recent article by Richtig et al. with interest but also with some concerns regarding their conclusions. Lymphoscintigraphy is an integral part of sentinel node biopsy for melanoma patients. Sentinel node biopsy (SNB) is considered by many to be the standard of care for melanoma greater than 1 mm in thickness or melanomas thinner than that but otherwise regarded as high risk. Without any doubt SNB provides prognostic and staging information and improves disease-free survival by reduci ...

UNLABELLED Poland's syndrome is characterized by variable clinical picture. Classic deformity consists of unilateral hypoplasia or aplasia of the sternocostal head of the pectoralis major muscle and ipsilateral hand malformations. Additionally on the affected side hypoplasia or aplasia of the breast in women is observed. Variable malformations in Poland's syndrome cause that there is no uniform treatment schedule. THE AIM OF THE STUDY was to analyze surgical treatment conducted in patients with ...
The management of ureteropelvic junction (UPJ) obstruction has evolved over the past 20 years in response to the development of new technology. Open surgery is still the reference standard against which all other surgical interventions must be measured. The surgical approach has, however, gone through rapid changes, and the open procedure initially described has evolved considerably. Endoscopic and laparoscopic approaches have largely supplanted open pyeloplasty for the majority of primary urete ...
In a prospective, randomized, masked study we compared the treatment of infantile esotropia using bilateral medial rectus muscle recessions of a graded amount from the insertion to standard 10.5-mm recession from the corneoscleral limbus.

Tumour cells may be dispersed into the wound when diagnostic or excisional biopsy is undertaken. This risk is reduced by using fine needle aspiration biopsy. The definitive excision of a soft tissue sarcoma may then be carried out in a more limited manner. In selected cases diagnostic and definitive operation may be combined, accepting the risk of excision of a benign lesion with unnecessarily broad margins. Aspiration cytology could possibly help the surgeon to decide on the extent of the excis ...
PURPOSE Following orthognathic surgery, patients use qualitatively different words to describe the altered sensation on their face that results from tissue inflammation and nerve injury. These words indicate normal, hypoesthetic, paresthetic, and dysesthetic sensations, and reflect the intrusiveness of the alteration. Our intent was to study the words chosen by patients from a standardized list to characterize sensory recovery during the first 6 months after surgery and to examine whether patien ...
