Effects of tourniquet during total knee arthroplasty. A prospective randomised study.
The effects of using a tourniquet during total knee arthroplasty were studied in 80 patients randomly allocated to two groups, either with or without a tourniquet. The groups were similar in mean age, gender, preoperative knee score and radiographic grading and the patients were all operated on by the same surgeon using one type of prosthesis. There was no significant difference between the two groups in operating time or total blood loss but postoperative pain was less in the patients in whom a tourniquet had not been used. They achieved straight-leg raising and knee flexion earlier and had fewer superficial wound infections and deep-vein thromboses. Total knee arthroplasty can be safely performed without the use of the tourniquet with the benefit that several adverse effects associated with its use can be avoided.

Detecting fractures of the scaphoid: the value of comparative X-rays of the uninjured wrist.
Pain or tenderness in the anatomical snuff-box following trauma suggests an injury to the scaphoid or surrounding soft tissues. It is often difficult to make a definite diagnosis since normal bone markings across the scaphoid can be misinterpreted as a fracture. To clarify whether a fracture is present or not, an X-ray of the uninjured scaphoid is taken in a comparable position to the most suspicious view. If bone markings are similar on both views, then a fracture can be excluded. Conversely, if the bone markings differ, then suspicion of a fracture may be confirmed. In combination with the clinical features, a more accurate diagnosis can be made and unnecessary out-patient and X-ray reviews can be avoided.

A new paradiscal injection technique for the relief of back spasm after chemonucleolysis.
Back spasm, or spasm of the back muscles, is the commonest adverse reaction encountered after chemonucleolysis. In order to overcome this troublesome complication, the authors present a new 'paradiscal injection technique'. After the injection of chymopapain into the affected disc, the needle is withdrawn to just outside the annulus. Bupivacaine is injected into the paradiscal 'space' which acts upon the paravertebral muscles. Eighty consecutive patients have been treated by chemonucleolysis with paradiscal injection for pain relief. All patients were discharged the same day or the following day and no immediate complications occurred. When reviewed 3 weeks later, only three (3.8%) patients complained of back pain (which was different in character to that present before the injection or was exacerbated by the injection). Pain persisted in the same patients until 6 months after the injection but was negligible. None of the remaining patients had developed back pain as a result of chymopapain. The authors suggest that the addition of paradiscal injection of bupivicaine after cymopapain injection can reduce the incidence of spasm of the back muscles. This technique is a major contribution to increasing the efficacy of chemonucleolysis for the treatment of herniated lumbar disc.

Drivers' elbow: a cause of ulnar neuropathy.
The ulnar nerve is vulnerable to compression and vibration injury in drivers who have the shoulder abducted and elbow flexed with the arm lying against the lower edge of the window. Three cases of ulnar neuropathy at the elbow are described in vehicle drivers.

Upper limb fractures in rugby in Huddersfield 1986-1990.
Most injuries sustained by rugby players affect the soft tissues, and fracture is relatively uncommon. Whereas the lower limb is most affected in footballers, the upper limb tends to be injured in rugby players. Thirty consecutive fractures and ten dislocations affecting the upper limb, sustained by 35 rugby players, are reported.

Internal fixation of closed tibial fractures for the management of sports injuries.
From 1985 to 1988, 90 closed tibial fractures were prospectively studied to assess the morbidity of such injuries to sports people and how this can be influenced by treatment regimens. All fractures were sustained during rugby or football matches. After random selection, 45 fractures were openly reduced and internally fixed (group A), and 45 fractures were manipulated under general anaesthesia and a long-leg plaster applied (group B). For patients in group A, below-knee plasters were used for 3 to 4 weeks, with immediate weight-bearing when tolerated. A total of 44 (98%) tibiae united clinically and radiologically within 14-18 weeks. Within 4 months of surgery 28 (62%) patients had returned to work and were able to play again by the following season. By 6 months 17 (38%) patients had resumed normal activities. In group B, only 24 (53%) tibiae united in a mean time of 16 weeks (range 12-40 weeks). Six (13%) patients required bone grafting for non-union, and one patient subsequently developed osteomyelitis. Only ten (22%) patients were back to work and playing sport again within 6 months of initial injury. It is concluded that internal fixation of closed tibial fractures as a primary procedure following low velocity sports injuries can be safely performed. It leads to a faster return to normal activities with fewer complications than does conservative treatment in plaster using contemporary methods.
