Ectopic ossification after hip arthroplasty.

The incidence of radiographically visible ectopic ossification around the hip joint was redorded in 145 hip joints of 132 patients treated by endoprosthetic replacement. There were 56 total hip replacements with a McKee-Farrar and 39 with a Brunswik type of endoprosthesis; in a further 50 hips the femoral head was replaced with a Moore or Thompson prosthesis. An identical antero-lateral surgical approach was used in all, without detachment of the greater torchanter. The patients were re-examined 3, 6, and12 months after the operation. The extent of ectopic ossification was graded from 0 to III and correlated with pain and with the function and mobility of the operated hip. Ectopic ossification of varied extent was recorded in 37 % after total hip replacement and in 38 % after replacement of the femoral head. Of these ossifications 95 % were recognizable within 3 months; they did not increase in size, but often in density during the following months. One case of bony ankylosis was noted. Ectopic ossification of slight (grade I) to moderate (grade II) degree did not cause pain or affect the function of the operated hip, but reduced the mobility of the affected hip. The difference in mobility between grade I and grade II was significant (p less than 0.05), and between grade 0 and grade II highly significant (p less than 0.001).

Primary operative fixation of long bone fractures in patients with multiple injuries.

Early mobilization is essential for patients with multiple long bone fractures associated with other injuries in order to avoid complications. Therefore, in 1969 we adopted a policy of rigid internal fixation of long bone fractures in such cases. To assess the results of this active treatment a number of consecutive patients were followed. The following conditions were necessary for the case to be included in this series: multiple injuries; treatment at the intensive care unit; and at least two long-bone fractures treated with internal fixation. During the period from 1969 to 1974 47 patients met all requirements. With primary operative fixation of long bone fractures of patients with multiple injuries it was possible to mobilize on crutches 29 patients out of 47 within 2 1/2 months of the accident, and 32 were allowed to leave the hospital within 3 months. With the exception of the death of an 80-year-old woman, no severe complications attributed to the operative treatment of these fractures occurred and 32 out of 47 patients returned to work within 16 months. The results in these 47 cases show that in patients with multiple injuries associated with several long bone fractures, primary internal fixation is preferable to the more conventional conservative methods.

Subcapital fractures of the femur treated with two thin Smith-Petersen nails.

The results of treatment of 71 patients with subcapital fractures of the femur, fixed with two thin Smith-Petersen nails, are presented, after a follow-up time of between 2 and 4 years. Excellent results of treatment were achieved in 39 out of 60 cases and good results in 11 cases. Six cases of ischemic necrosis of the femoral head were recorded, and there were four cases with pseudarthrosis of the femoral neck, one developed because of postoperative infection and three were attributed to an imperfect operative technique. The method is recommended for subcaptial femoral neck fractures amenable to closed reduction and internal fixation. Pseudarthrosis may be prevented by good reduction of the fracture and a careful nailing technique.

Rubber band ligation of haemorrhoids. Analysis of 281 patients.

The problems and discomfort resulting from haemorrhoidectomy have led to the development of other forms of therapy. Rubber band ligation has become a popular method of treatment for internal piles. The results are comparable with those achieved by excisional surgery. The material consists of 281 consecutive patients with internal haemorrhoids treated with rubber band ligation. The average follow-up was 12 months. 239 of the 262 patients re-examined were entirely free of discomfort (91%). In all the eight cases with mucosal prolapse the ligation was not successful. In these as well as in patients with rubber allergy, other forms of treatment are suggested.

Pertrochanteric fractures of the femur treated with a Küntscher trochanter nail.

Thirty-nine patients with pertrochanteric fractures were treated with the Küntscher trochanter nail. Six were males and 33 females. Their mean age was 76 years. Excellent or good results of treatment were recorded in 25 cases, and good union of the fracture was noted in 19 patients within 4 months and in 15 cases as early as 2 months after the operation. The primary mortality rate was of the same order as with other methods of nailing, 15% in this series. The operation is easy and short, and is suitable at least for stable pertrochanteric fractures of elderly patients.
