From September 1980 to March 1985, 123 cementless, polyethylene Endler acetabular sockets of the threaded, tapered type were implanted in 115 patients at the department of orthopaedic surgery, Balgrist, University of Zurich. The first 102 Endler sockets, in combination with a Zweymüller femoral prosthesis, have been followed up till April 1988, this corresponding to an average observation period of 57.4 months. 12.8% of the total number of qualitative criteria and the Sutherland method, and further 20.6% of the cases were suspected of having loosened, so that a figure of 33.3% (34 loosened sockets) resulted. A definite correlation between loosening and the following factors were determined: females, limping, Trendelenburg sign, period of implantation and severe, continuous pain. No correlation was found between either tolerable pain, age, weight, or para-articular ossification, and loosening. The cementless artificial hip joint of Endler/Zweymüller combination led to a definite improvement of independency and living quality through increase in mobility and reduction of pain.

Cesarean section scar ectopic pregnancy (CSEP) is defined as a pregnancy in which blastocyst is implanted within the scar of previous cesarean section. It is a rare form of ectopic but its frequency is increasing due to increasing rate of cesarean section. In this case, a 36 years old G3P2A0, married for 10 years, previous II C/Sections, LCB 7 years back, presented with ultrasound report of the viable pregnancy at 11+1 weeks with gestational sac incorporating into previous scar of cesarean section. She was otherwise asymptomatic and stable. Serum Beta hCG was 73664.78 IU/L. Laparotomy was done as an elective procedure. Dense adhesions were noted on opening the abdomen between anterior abdominal wall, uterus, bladder and gut. Scar ectopic pregnancy was excised after dissecting the adhesions. Her Serum Beta hCG 48 hour post-operatively was 1397.0 IU/L.Patient was discharged home on 2nd post-operative day in good condition. She was counselled about risk of a recurrent scar ectopic and rupture of uterus in next pregnancy. Her serum Beta hCG declined to normal by 4 weeks post operatively.
