Nerve root blocks in the treatment of lumbar radicular pain. A minimum five-year follow-up.
In a previous prospective, randomized, controlled, double-blinded study on the effect of nerve root blocks on the need for operative treatment of lumbar radicular pain, we found that injections of corticosteroids were more effective than bupivacaine for up to thirteen to twenty-eight months. We performed a minimum five-year followup of those patients who had avoided surgery. ⋯ The majority of patients with lumbar radicular pain who avoid an operation for at least one year after receiving a nerve root injection with bupivacaine alone or in combination with betamethasone will continue to avoid operative intervention for a minimum of five years.

Minimum ten-year results of primary bipolar hip arthroplasty for degenerative arthritis of the hip.
Bipolar hip arthroplasty has been advocated by some as an alternative to total hip arthroplasty for the treatment of degenerative arthritis of the hip. We sought to assess the results of this procedure at our institution after a minimum duration of follow-up of ten years. ⋯ This bipolar cup, when used for hemiarthroplasty in patients with symptomatic arthritis of the hip, was associated with unacceptably high rates of pain, migration, osteolysis, and the need for revision to total hip arthroplasty, especially when the acetabulum had been reamed. To the extent that these findings can be generalized to similar implant designs with conventional polyethylene, we do not recommend bipolar hemiarthroplasty as the primary operative treatment for degenerative arthritis of the hip.

The QuickDASH, an abbreviated form of the Disabilities of the Arm, Shoulder and Hand Questionnaire, uses a graded-adjectives ordinal measurement response scale. In order to improve the sensitivity of the measure and to make it compatible with widely used measures of pain and disability, a visual analog scale version was developed. The present study investigated the reliability of the new version over time when used for the evaluation of patients undergoing treatment. ⋯ The QuickDASH visual analog scale questionnaire has acceptable reliability over time, and it can be used as an alternative to the original QuickDASH.
