Aim: The evaluation of the middle term behaviour of the Wagner-type stems in dysplastic femurs and the presentation of the technical and surgical differences with the implantation of a Wagner stem.

Materials and Methods: Between 1997 and 2008 we implanted 64 Wagner stems in 58 patients. Average age at the time of implantation was 64 years. 52 patients was operated because of DDH, and 12 had had previous osteotomy. All patients were prospectively evaluated radiographically and clinically at annual intervals. Functional outcome was assessed with Harris Hip Score and Oxford Score.

Results: Mean follow-up of these series was 4 years (11-1)One stem was revised because of fracture of the lesser trochander and two more patients were re-operated for open reduction. With the re-operation as end-point and 95% Confidence Interval survivorship rate was 98, 5%. There were no progressive radiolucent lines. Stem migration was at an average 2mm (1–6) during the first two years and remained stable thereafter. There was no deep infection in these series. After the second year a dense zone is evident in all Gruen zones at the implant –bone interface with a width of 2–3 mm.

Discussion: Dysplasia of the proximal femur may pose significant technical problems during THA due to the distortion of the geometry and the narrowing of the femoral canal. The sort, conical Wagner type stems can offer a very good alternative is such patients. They allow control of the anteversion and they are able get a good press-fit despite the metaphyseal/diaphyseal mismatch and the femoral bowing.

Conclusions: Wagner type stems are a reliable alternative when performing THA in patients with dysplastic femurs

Introduction: The aim of this study is to present the effect of various local anaesthetics, in particular solution concentrations, in peri- and post-operative analgesia in patients with carpal tunnel syndrome (CTS).

Material and Method: 105 patients with CTS (81 female, 24 male, ages 27–79) underwent carpal tunnel release under local anaesthesia. The patients were divided into 5 groups (xylocaine 2%, ropivacaine 0.75%, ropivacaine 0.375%, chirocaine 0.5%, chirocaine 0.25%). A tablet of Gabapentin (Neurontin) 400mg was administered to some patients of each group (41 pts of the 105pts) 12 hours prior to surgery. All patients were evaluated immediately after surgery, in 2 weeks and 2 months postoperatively according to VAS pain score, grip strength, finger active motion and two point discrimination. Postoperative complications were also reported.

Results: Anesthesia was immediate after the local injection. All patients improved postoperativelly regarding relief from pain and paresthesias. There was no statistically significant difference in grip strength before and after surgery. Only 10 patients used paracetamol immediately after surgery, without any statistically significant correlation to any group of patients. 1 patient developed complex regional pain syndrome 2 months after surgery.

Conclusion: The use of local anaesthesia in carpal tunnel release surgery is beneficial in providing immediate intraoperative effect and recovery and mobilization after surgery. Rehabilitation seems to be irrelevant of the type of local anaesthetic that was used during the procedure. Small solution concentrations of local anaesthetics (ropivacaine 0.375%, chirocaine 0.25%) provide adequate analgesia during surgery and provide a normal postoperative course.

Introduction: The value of arthroscopy, fluoroscopy, and e-learning courses (focusing on minimally invasive surgical techniques) for the treatment of intra-articular distal radius fractures (I-ADRF), remains controversial. This study compares the outcomes after fluoroscopically assisted (FA) reduction and external fixation of distal radius fractures, with or without concomitant arthroscopic evaluation.

Materials and Methods: Forty-seven patients with I-ADRF underwent FA external fixation and percutaneous pinning. Among them 23 had additional arthroscopic evaluation of their wrist. For teaching purposes procedures with the use of fluoroscopy and arthroscopy were recorded and adapted as a course for the On-line Performance Support Environment for Minimally Invasive Orthopaedic Surgery (“OnLineOrtho” EU- sponsored project). The context of these courses was incorporated in an intelligent medical performance support environment. The duration of the procedure, the surgical findings and the outcomes were recorded.

Results: The follow-up period ranged from 24 to 62 months and the patients were evaluated at 3, 6, 12 and 24 months. The addition of arthroscopy prolonged the procedure by 25 minutes but diminished the number of images obtained by the image intensifier by 5. After arthroscopic evaluation the placement of subchon-dral pins was changed, because of step-off, in 11 of 23 patients. Also tears of the TFCC (14 of 23 patients), perilunate ligaments (16) were depicted. Patients who underwent additional arthroscopic evaluation had significantly better supination, extension and flexion at all time points than those who had only fluoroscopically assisted surgery. The value added by e-courses and the online performance support system is highlighted through the recognition of the systems effectiveness in e-training.

Discussion: During reduction and fixation of I-ADRF, arthroscopy is a very useful tool for the inspection of the articular surface, the ligaments and the TFCC. Long-term evaluation revealed that patients with additional arthroscopy returned to their previous activities in shorter periods and had better supination, flexion, and extension than patients with FA procedures. Fluoroscopy is essential for the minimally invasive surgical treatment of intra-articular distal radius fractures, whereas arthroscopy is an additional valuable tool that improves the outcome, and e-courses are useful adjuncts for teaching purposes.

Aim: According to the literature, mortality rate after hip fracture (HF) approaches 20% per year. Morbidity, mortality and rehabilitation after HF are the objectives of this study.

Material: We followed 192 patients (72 men −120 women, age: 78.6 years), who suffered from HF: intertrochanteric (64%), subcapital (30%) or subtrochanteric (6%). Before the injury 70% of the elderly lived with relatives, yet self-assisted, 17% with relatives but were unabled, 10% completely independent and 3% unabled and alone or instituted. Gait before injury was independent in 50%, while 48% used a walking aid and 2% were in bed.

Results: In a minimum postoperative 12-month follow-up, 75% of the patients were questioned. Mortality rate was 21,8% (men 37,5% - women 12,5%): 7% deceased while in hospital, 57% during the 1st trimester and 36% in the next 9 months. Mean average hospital stay: 8,3 days and the mean interval from injury to operation: 2,7 days (0–13). Direct postoperative complications were recorded in 26,5%. Rehabilitation was continued for 32% of patients in specialized centers and for 7% at home and 35% of patients regained their pre-injury functional level, whereas 37% needed a walking frame. Family members modified their activities in 40% of cases.

Conclusions: Mortality and morbidity in elderly patients with HF overcome 21% and 26% respectively, whereas only 35% of patients regained their pre-injury functional level. Despite the beneficial effect of family support, the lack of organized rehabilitation program and the delay of operation are potential negative factors for the patients outcome.
