Operative treatment of chronic acromioclavicular dislocation.

Six patients (median age 35 years) were reviewed at an average of 24 months after operation for chronic acromioclavicular dislocation. The operation consisted of resection of the lateral part of the clavicle and transference of the coracoacromial ligaments as a substitute for the coraco-clavicular ligament. The ligament was secured by an AO screw for 6 weeks. In five patients the reasons for operation were pain, when working and sleeping, and, in one patient, pressure on the skin. Three of the patients complained of weakness. At follow-up the results were excellent in four patients and good in two. Three patients had mild pain when lying on the shoulder and three had complaints where the flake of bone attached to the transferred ligament was inserted into the clavicle. We now recommend a modification of the method, omitting the flake of bone.

Fractures after hemialloplastic hip replacement.

Forty-four patients sustaining ipsilateral femoral shaft fractures after hemialloplastic hip replacements are evaluated according to risk factors for the fractures, treatment and social costs. The fracture incidence was 0.10, and almost half of the fractures occurred within 1 year after the initial alloplastic operation. Possible factors increasing the risk of secondary fracture included loosening of the prosthesis (eight cases), osteoporosis (14 cases), varus angulation of the femoral stem (28 cases), calcar resorption (nine cases), major capsular calcifications (four cases), and cortical defects at the tip of the stem (three cases). The importance of correct insertion of the prostheses is emphasized. The degree of mobilization after fracture healing was overall reduced and most pronounced with increasing age and not correlated to treatment. The earliest mobilization was obtained in patients treated with long-stem prostheses supplemented with internal fixation, and this method of treatment is advocated.

Netz or Kirschner pins in the treatment of olecranon fractures?

To evaluate problems in connection with Netz or Kirschner pins after internal fixation of olecranon fractures using the tension-absorbing wire technique, 14 men (median age, 60 years), and 32 women (median age, 67 years) were compared. In 21 patients the operation was performed with Netz pins and in 25 patients with Kirschner pins. The fracture healing time did not differ between the two groups. Skin problems due to migration or rotation of the pins were seen in four patients operated with Kirschner pins; since the Netz pins are constructed so as to avoid pin migration, this did not occur with Netz pins. Skin pressure problems, or perforation related to the looped ends of the cerclage wires, were seen in two patients in each group. These complications are not influenced by the type of pins used. In one patient the Netz pins caused further fragmentation of a small bone fragment, due to their relatively wide borehead. Supported by the results in this study, we recommend the Netz pins in the treatment of olecranon fractures when using the tension-absorbing wire technique.

The predictive value of the third day temperature in the decision whether to continue or terminate antibiotic treatment in perforated appendicitis.

The third day temperature is frequently used in the decision whether to continue or terminate antibiotic treatment following appendicectomy in perforated appendicitis. To assess the value of the third day temperature in predicting intraperitoneal infectious complications we studied 235 consecutive patients treated with a 3-day course of cefoxitin after surgery for perforated appendicitis. The results demonstrated that regardless of the level of elevated temperature chosen, the predictive value ranged between 16 and 33%. In consequence, elevated third day temperature per se does not provide any rational basis for continuing antibiotic treatment in order to prevent intraperitoneal infectious complications following appendectomy in perforated appendicitis.

Hemi-arthroplasty of the hip followed by ipsilateral fracture of the femoral shaft.

In a series of 74 ipsilateral fractures of the femoral shaft in relation to hemi-arthroplasties, treatment by a cemented long-stem total hip replacement was found to be superior to conservative treatment or internal fixation without removal of the prosthesis. Acceptable clinical results were obtained in 89 per cent of these cases.

Snapping hip.

Thirty-one snapping hips in 24 patients were followed for 4 (1-11) years after operation. At follow-up, snapping persisted in nine hips, in three cases accompanied by pain. The femoral neck angle was less in the patients (128 degrees) than in a control group (134 degrees).

Conservative or surgical treatment of acromioclavicular dislocation. A prospective, controlled, randomized study.

In a prospective, controlled, randomized study of acute acromioclavicular dislocations, we compared conservative and operative treatment (the Phemister procedure) with regard to the clinical results, complications, and social costs. Forty-one patients were operated on and forty-three patients were treated conservatively. Two patients who were operated on and three who were treated conservatively had to have the lateral extremity of the clavicle resected because of pain. The rehabilitation period was significantly shorter with non-operative treatment, and after thirteen months there was no difference in the clinical results. There were no serious postoperative complications, but about half of the patients who were operated on had problems with the metallic device, such as breakage or migration of the pins, or both, and six patients had a superficial infection. For most patients with total acromioclavicular dislocation we recommend conservative treatment with a sling until the patient is free of pain. Operation should be considered in thin patients who have a prominent lateral end of the clavicle, in those who do heavy work, and in patients whose daily work requires that the shoulder often be held in about 90 degrees of abduction and flexion.

Partial or total open meniscectomy? A prospective, randomized study.

In order to compare partial with total meniscectomy a prospective clinical study of 200 patients was carried out. At arthrotomy 100 patients were allocated to each type of operation. The two groups did not differ in duration of symptoms, age distribution, or sex ratio. The operations were performed as conventional arthrotomies. One hundred and ninety two of the patients were seen at follow up 2 and 12 months after operation. There was no difference in the period off work between the two groups. One year after operation, 6 of the 98 patients treated with partial meniscectomy had undergone further operation. In all posterior tears were found at both procedures. Among the 94 patients undergoing total meniscectomy, 4 required further operation. In each, part of the posterior horn had been left at the primary procedure. One year after operation significantly more patients who had undergone partial meniscectomy had been relieved of symptoms. However, the two groups did not show any difference in the degree of radiological changes present.

Ruptures of the extensor mechanism of the knee joint. Clinical results and patellofemoral articulation.

The functional results of 28 cases of rupture of the quadriceps and patellar tendons are reported. Excellent or good results were noted in 15 of 18 quadriceps and 7 of 10 patellar tendons. Radiographic comparison with the opposite knee disclosed incongruences between the patella and the femoral groove in the tangential view and/or cranial-caudal position of the patella in the lateral view in 13 of the quadriceps tendon ruptures and seven of the patellar tendon ruptures. Patients with residual pain had patellofemoral incongruity but since two-thirds of the patients with incongruity were asymptomatic, incongruity alone may not be the cause of the symptoms. There was no positive correlation to muscular strength or range of movement. Nevertheless, exact adaptation of the patellar tendon and periarticular tissue seems necessary to obtain correct patello-femoral articulation. Reinforcement of the tendon with a wire cerclage is recommended to decrease the tension on the suture line and the consequent risk of a secondary rupture. In acute ruptures of the quadriceps tendon end-to-end sutures are sufficient.
