Introduction: The treatment of “congenital hip disease” by total hip arthroplasty is now well established, but the indications for this type of surgery, the preoperative planning, the selection of the stem and the technique to be followed are still open to debate.

Aim of the study: The purpose of this study is to analyse the long-term follow up after use of the cementless-system (CLS) femoral component designed by Spotorno in dysplastic or congenitally dislocated hips.

Material and Methods: Our study includes 70 hips in 59 patients, 49 females and 10 males, 36 left hips and 34 right hips that treated with total hip arthroplasty from 1987 to 2000. The mean age of the patients was 48.5 years (range 34–74 years). Forty-one hips were congenitally dislocated and twenty-nine were severe dysplastic. Preoperative planning with CT and CAD-CAE system were used for selection of the stem. 11 patients had bilateral total hip arthroplasties with Spotorno CLS stem. Many different cups were used.

Results: The mean follow up was 8.1 years (range 2–14 years). No patients were lost during the follow-up period. Patients were evaluated clinically with Merle d’ Aubigne and Postel hip score. There was a significant postoperative clinical improvement of the mean pain score by 3.7 points, of walking ability by 2.2 points and of motion by 2, 6 points. Thigh pain was not reported. There were no deep infections or mechanical loosening that required revision of the femoral component.

Conclusions: Although, the femoral component Spotorno CLS is used to every kind of hip diseases, had excellent long-term clinical results in adults, with dysplasia or congenital hip dislocation. Spotorno CLS uncemented femoral component represents an attractive option for adults with “congenital hip disease”.

Aim: The primary purpose of this study was to establish data concerning normal hand grip strength in the population of N.W Greece.

Material and Methods: The Jamar dynamometer was used to measure grip strength. A sample of 115 males and 117 females, with no extremity disability or injury, aged 21 to 58 years, from the Ioannina area was tested. The dynamometer was tested in a standing position, with shoulder adducted and neutrally rotated, elbow flexed at 90 degrees and forearm and wrist in neutral position. Each participant was asked to grip first with the right and then with the left hand three consecutive times. The highest grip strength for each hand was used for analysis. All complementary factors such as age, sex, height, weight, hand dominance for writing and exercise and living habits were recorded.

Results: Grip strength diminishes curvilinearly with age, and men are consistently stronger than women. Mean maximum grip for women was 67 pounds and for men was 123 pounds. The hand dominance does not significantly affect hand strength scores. The mean grip strength of the left hand was about 90% that of the right hand. In left-handed participants, mean grip was the same for both hands. The results from this study showed that sex is the most important determinant of hand grip strength.

Conclusions: The random sample, the high participation rate of this study and the number of the factors that affect the hand strength give the highest validity in this study. These data suggest a basis to help hand surgeons as a guide regarding grip strength in the treatment of upper extremity pathologic conditions and postoperative evaluation.
