Bone scan in the patellofemoral pain syndrome.

Eighty patients who complained of retropatellar pain underwent evaluation by bone scintigraphy, intraosseous pressure determination, radiography, arthroscopy and physical diagnostic tests. The bone scans showed that 48% of the painful knees had an increased uptake compared with 9% for the normal joints. A highly significant correlation was evident between an increased uptake and established chondromalacia. For the diagnosis of a high pressure patella, radiography was only 7% sensitive (6/88), compared with 44% (39/88) for bone scintigraphy and 78% for the clinical "sustained flexion" test. The positive predictive value of a bone scan for detecting a high pressure patella was 0.72 (39/54). The best predictor was a positive sustained flexion test with a predictive value of 0.85 (69/81).

Neuropathic osteonecrosis of the knee in childhood. Two cases of myelomeningocele.

Two girls, aged 11 and 7 years, with myelomeningocele had osteonecrosis in the lateral tibial epiphysis and in the medial femoral condyle, respectively. Both girls suffered from sensory impairment of the affected area and presented with warmth and swelling of the knee. No signs of infection were found. The necroses seen in radiographs were confirmed by biopsy and 99mTc-MDP scintigraphy. The lesions showed only little tendency to heal, and rather severe growth disturbances developed despite treatment in long leg calipers. One of the girls was unable to walk because of the loss of muscular power during the long period of bracing.

Spinal or general anaesthesia for surgery of the fractured hip? A prospective study of mortality in 578 patients.

The mortality following surgical correction of upper femoral fractures was investigated in 578 patients, over the age of 50 yr, randomly allocated to receive spinal (bupivacaine) or general (enflurane or neurolept) anaesthesia. Thirty days after surgery the mortality was 6% after spinal and 8% after general anaesthesia (ns). Six months to 2 years after surgery the mortality was identical in the two groups. There were no differences with respect to ambulation and discharge. The estimated blood loss was smaller (P less than 0.05) in patients receiving spinal anaesthesia. Regardless of the anaesthetic technique, a high short-term mortality was related to age, male sex, and trochanteric fracture, whereas excess long-term mortality was related to male sex and high ASA scores.

Ruptured semimembranosus bursa--an unusual complication following sports injury of the knee.

An exceptional complication of a slight sports injury of the knee with rupture of the semimembranosus bursa in a 29-year-old male football player is reported. The diagnosis was verified by immediate arthrography, consequently the possibility of thrombophlebitis could be ruled out. Anticoagulation is dangerous and contraindicated in rupture of the semimembranosus bursa due to the risk of developing compartment syndrome. Simple bed-rest for a week gave complete relief of pain.

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.

Sports injuries of the knee ligaments--a prospective stress radiographic study.

Forty-six patients were entered into a prospective clinical and stress radiographic study done to assess the value of acute surgical treatment of injuries to the knee ligaments sustained during sports activities. After an average follow-up period of 5 1/2 years (range 4-6 1/2 years) medial instability was found only in two patients, both of whom were in the group with isolated rupture of the medial collateral ligament. Nine of the 29 patients in this group developed rotatory instability, but it was moderate and did not give rise to symptoms. Among the 17 patients with either injuries to the anterior cruciate ligament or combined injuries, anterior drawer instability persisted in seven, with an insufficient functional result in five. None of these 17 patients were able to resume competitive sport. Those patients who had not exercised physically just before the injury proved to have a significantly greater total instability than those who had. Therefore, routine limbering-up is recommended before sports activities.

Massive Gorham osteolysis of the right hemipelvis complicated by chylothorax: report of a case in a 9-year-old boy successfully treated by pleurodesis.

In a 9-year-old boy with progressive massive osteolysis (Gorham disease) of the right hemipelvis, the course was complicated by life-threatening chylothorax. A total of 42.6 L of chylous fluid was tapped over a 3-month period. A simple thoracoscopic intervention with tetracycline instillation was successful, and there has been no recurrence of the pleural effusion.
