The treatment of pyogenic bone and joint infections by closed irrigation-suction.

An improved method of closed irrigation-suction treatment of bone and joint infections is described. The method utilizes a crisscross flow-reversal system using a double tube which prevents obstruction of the tube. A series of 154 patients with acute and chronic bone and joint infections were treated with closed irrigation in 172 closed irrigation-suction procedures. One hundred forty-eight cases (86.0%) were treated successfully, 7 cases (4.1%) were improved, and 17 cases (9.9%) were failures. Blood concentration levels of antibiotics were examined during closed irrigation. Absorption of antibiotics from the wound was insignificant. Culture and sentivity tests of drainage during closed irrigation are used to monitor the cleansing of the wound. Serum hepatitis was seen in 4 cases within the hematogenous group and in 6 cases within the traumatic group. Postoperative bleeding during irrigation was an important complication.

Fatigue fracture of the pelvis after total knee replacements: report of a case.

Fatigue fracture of the pelvis in a 66-year-old woman with rheumatoid arthritis was recognized after bilateral total knee replacements. The fatigue fractures occurred sequentially and bilaterally in the superior and inferior pubic rami. Satisfactory recovery occurred in response to conservative treatment. The fracture of the right superior ramus failed to unite. Fatigue fracture should be suspected if there is pain in the pectineal region after knee arthroplasty.

[Shoulder movements during abduction and adduction of quadriplegic patients (author's transl)].

The relationship between glenohumeral and scapular movements during abduction and adduction of the limb in the scapular plane were studied in twenty normal subjects and nine quadriplegic patients by analysis of roentgenograms and enveloped electromyograms with electrogoniometer. In normal subjects the ratio of glenohumeral to scapulothoracic movement was 4.2 : 1 for the range 0-30 degrees and 1.7 : 1 for the range 30-150 degrees for abduction, and 1.9 : 1 for the range 150-30 degrees and 1.7 : 1 for the range 30-0 degrees for adduction. In comparing quadriplegic patients with normal subjects, outstanding medial shift of the scapula was observed in early phase of abduction, elevation, and upward rotation of the scapula which were limited through whole abduction. Distances of the shift of the scapula in quadriplegic patients were the same as those in normal subjects in the final phase of adduction. In enveloped electromyograms of normal subjects, each activity of the six sampled muscles, increased or decreased gradually during abduction and adduction in similar relationships. The upper fiber of the trapezius demonstrated the highest activity through abduction and adduction. During abduction and adduction the supraspinatus showed undulated wave patterns and had the plateau at 80-140 degrees. The activity of the supraspinatus was higher than that of the deltoideus statistically for the range 0-40 degrees for abduction. In each quadriplegic patient the patterns of muscle activities during abduction and adduction were characteristically peculiar and did not indicate any constant relationship findings in normal subjects, irrespective of the functional level.

Avulsion fracture of the tibial attachment of the posterior cruciate ligament. Indications and results of delayed repair.

In a series of delayed repair in 8 instances of avulsion fracture of the tibial attachment of the posterior cruciate ligament, 6 were isolated avulsion fractures of the tibial attachment of the posterior cruciate ligament and 2 were associated with the fractures of the tibial condyle. Staple fixation was used exclusively. The detachment of the posterior horn of the meniscus was observed in 6 of 8 cases. Four cases, in which the surgery had been carried out within 7 weeks after the injuries, had excellent results. The other cases in which the surgery had been carried out more than 11 weeks after the injuries, had less than satisfactory results. Pain on motion or synovial effusion disappeared but residual anteroposterior instability remained. Repair of the avulsion fracture of the posterior cruciate ligament is recommended in cases of delayed or non-union with symptoms.

[Study on tobramycin concentration in bone marrow (author's transl)].

Tobramycin (TOB) concentration in the bone marrow of tibia was examined 1, 2, 3 and 4 hours after intramuscular injection of 60 mg: TOB concentration in the bone marrow of tibia 1 hour after injection was 2.8 +/- 0.578 microgram/ml. Ratio to serum was 87.5%. TOB concentration in the bone marrow of tibia 2 hours after injection was 1.6 +/- 0.480 microgram/ml. Ratio to serum was 94.1%. TOB concentration in the bone marrow of tibia 3 hours after injection was 1.1 +/- 0.337 microgram/ml. Ratio to serum was 84.6%. TOB concentration in the bone marrow of tibia 4 hours after injection was 0.8 +/- 0.372 microgram/ml. Ratio to serum was 80.0%. Penetration capacity of TOB into the bone marrow of tibia was excellent.

Isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament.

Twenty-one patients with isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament were treated in our hospital during the period 1965 to 1976. Twelve of the patients had fresh injuries and nine, injuries with delayed union or non-union. Twelve of the twenty-one patients were treated conservatively and nine, by surgical repair by means of staple fixation. Detachment of the posterior horn of the meniscus with an avulsed and displaced bone fragment was found in five of the nine patients operated on. All the patients were followed for an average of four years and eight months. Satisfactory results were obtained in every instance.

[Study on cephaloridine concentration in bone marrow (author's transl)].

Cephaloridine (CER) concentration in the bone marrow of tibia was examined 1, 2, and 3 hours after intramuscular injection of 1 g. CER concentration in the bone marrow of tibia 1 hour after injection was 26.0+/-8.927 microng/ml. Ratio to serum was 78.5%. CER concentration in the bone marrow of tibia 2 hours after injection was 20.6+/-5.003 microng/ml. Ratio to serum was 87.3%. CER concentration of bone marrow of tibia 3 hours after injection was 14.8+/-4.79 microng/ml. Ratio to serum was 91.9%. Difference of concentration between in bone marrow and serum was not statistically significant. Penetration capacity of CER into the bone marrow of tibia was excellent.

Rupture of the pectoralis major. Report of 2 cases.

Two cases of rupture of the pectoralis major are reported, one caused by excessive tension and direct violence, while the other was a result of direct violence alone. The site of the rupture was at the lateral third portion of the pectoralis major in one and at the musculotendinous junction in the other. Both patients were treated surgically, and regained full function of their shoulders. Review of the literature suggests that surgical repair is generally advisable and more gratifying than conservative management.

Bone and joint lesions in decompression sickness.

1 Of 450 divers, 268 (59.5%) has aseptic necrosis of bone; 81 had articular lesions. 2 In proportion to duration of diving experience and maximum depth of diving, incidence of bone necrosis increases. 3 The radiological lesions have been classified by modified Ohta-Matsunaga criteria. 4 Yearly progress of bone changes were mentioned. 5 Pathological appearances of aseptic necrosis of bone in divers are compared with different types of bone necrosis. 6 Experimental studies for aseptic necrosis were mentioned. 7 Etiology of bone necrosis is not yet clear, but some etiological factors were discussed. It was suggested that fat embolism was an important factor, because fat embolisms were seen in our pathological findings of the divers and compressed-air workers. 8 Periodic radiological examination of the bones of divers and compressed-air workers should be carried out. It is important to research the new modified decompression table to prevent bone necrosis. 9 Surgical treatment of bone necrosis was mentioned.
