The appearance of kissing contusion in the acutely injured knee in the athletes.

BACKGROUND: Bone contusions are often identified at magnetic resonance imaging (MRI) in the acutely injured knee. Contusions of both surfaces of the joint are known as kissing contusions. OBJECTIVE: To determine the frequency, type, and distribution of kissing contusions occurring in association with injuries of the knee joint. METHODS: 255 MRI examinations in athletes with acutely injured knees (197 men; 58 women; mean age 24.2 years) were reviewed by two independent examiners; 219 MRIs were done within the first month after the injury and 36 within two to four months. None of the knees had been injured before. No fractures were present on x ray. RESULTS: Bone contusions were diagnosed in 71 cases (27.8%); 55 (22.5%) were identified as single contusions and 16 (6.3%) as kissing contusions. Eight of the kissing contusions were associated with anterior cruciate ligament tears, three with menisceal tears, four were isolated lesions, and one was delayed, following a menisceal tear. The 32 bone contusions (16 kissing contusions) were located as follows: lateral femoral condyle (n = 14; 8 type I, 6 type II); lateral tibial condyle (n = 9; 3 type I, 1 type II, 5 type III); medial tibial condyle (n = 7; 2 type I, 5 type III); medial femoral condyle (n = 2; both type I). The associated injuries were confirmed by arthroscopy in 12/16 patients. CONCLUSIONS: Kissing contusion is a significant injury often associated with ligamentous or menisceal injuries. Type I lesions are most common on the lateral femoral condyle and type III on the lateral tibial condyle.

Segmental spinal correction of idiopathic scoliosis. Luque rods and Hartshill rectangle in 30 patients followed for 2-6 years.

30 patients with idiopathic scoliosis were treated by posterior spinal arthrodesis using the Luque (8 patients) and Hartshill (22 patients) rodding systems with sublaminar segmental wiring. Patients were followed for 2 to 6 years. In most cases, postoperative correction exceeded safety correction limits (lateral bending film plus 10 degrees). Final correction was 55%, while derotation was not significant (average 3 degrees). No neurological deficit was noted. Postoperative bracing was not applied and there was 1 patient with broken rods (Luque trolley system without fusion) and 1 patient with broken wires in 4 segments. Allogenic blood transfusion was avoided in 19 patients by preoperative donation of autologous blood, in combination with salvage of intraoperative shed blood. We found segmental spinal wiring with either rods or rectangles to be a safe method for correction of scoliosis in experienced hands. It offered satisfactory stability and fusion rate with no need for external support.

Adolescent idiopathic thoracic scoliosis. A prospective trial with and without bracing during postoperative care.

Fifty patients with adolescent idiopathic scoliosis treated by posterior fusion and Harrington instrumentation augmented by a Cotrel bar or by sublaminal Luque wires were studied in a prospective trial to ascertain the need for postoperative bracing. Twenty-five patients wore a plaster brace postoperatively for six months, while 25 were managed without a brace. The mean loss of correction from the first standing postoperative radiograph to one obtained two years later was 7 degrees in the braced group, and 6.3 degrees in the unbraced group, the difference not being statistically significant. We conclude that postoperative bracing is unnecessary after augmented Harrington instrumentation.

IgD multiple myeloma. A case report.

A patient with a fracture of the left femur was investigated for suspected multiple myeloma. Serum total proteins, protein electrophoresis, and immunoglobulin G, A and M levels were within normal limits. Bence Jones proteinuria of the lambda type was present. Subsequent investigations revealed the presence of IgD myeloma.

Scaphoid fractures in children.

Fracture of the carpal scaphoid before skeletal maturity represents 0.34% of all fractures in children and 0.45% of children's upper limb fractures. Seventy-seven children, with a mean age of 11 years (range 8-14 years), suffered a scaphoid fracture in Nottingham, England, between 1977 and 1984 inclusive. Sixty-four of them have been personally reviewed. The mechanism of injury was usually a fall onto the outstretched hand and in the majority was an undisplaced fracture of the distal third of the bone. Immobilization in a scaphoid type of forearm-hand cast led to union in virtually all instances. Nonunion is very rare in treated cases of fresh fracture of the carpal scaphoid.
