ReviewStandard surgical protocol to treat elbow dislocations with radial head and coronoid fractures. Surgical technique.
The results of elbow dislocations with associated radial head and coronoid fractures are often poor because of recurrent instability and stiffness from prolonged immobilization. We managed these injuries with a standard surgical protocol, postulating that early intervention, stable fixation, and repair would provide sufficient stability to allow motion at seven to ten days postoperatively and enhance functional outcome. ⋯ Use of our surgical protocol for elbow dislocations with associated radial head and coronoid fractures restored sufficient elbow stability to allow early motion postoperatively, enhancing the functional outcome. We recommend early operative repair with a standard protocol for these injuries.

Randomized Controlled Trial Clinical TrialBotulinum toxin injection in the treatment of tennis elbow. A double-blind, randomized, controlled, pilot study.
A recent report has suggested that local injection of botulinum toxin type A is an effective method of treatment for chronic tennis elbow. The toxin is thought to provide temporary paralysis of the painful common extensor origin, thereby allowing a healing response to occur. To test this theory, we performed a double-blind, randomized, controlled, pilot trial comparing injections of botulinum toxin type A with those of a placebo (normal saline solution) in the treatment of chronic tennis elbow. ⋯ With the numbers studied, we failed to find a significant difference between the two groups; thus, we have no evidence of a benefit from botulinum toxin injection in the treatment of chronic tennis elbow.

Early mortality after hip fracture: is delay before surgery important?
Hip fracture is associated with high mortality among the elderly. Most patients require surgery, but the timing of the operation remains controversial. Surgery within twenty-four hours after admission has been recommended, but evidence supporting this approach is lacking. The objective of this study was to determine whether a delay in surgery for hip fractures affects postoperative mortality among elderly patients. ⋯ The thirty-day mortality following surgery for a hip fracture was 9%. Patients with medical comorbidities that delayed surgery had 2.5 times the risk of death within thirty days after the surgery compared with patients without comorbidities that delayed surgery. Mortality was not increased when the surgery was delayed up to four days for patients who were otherwise fit for hip fracture surgery. However, a delay of more than four days significantly increased mortality.

ReviewTreatment of osteonecrosis of the femoral head with implantation of autologous bone-marrow cells. Surgical technique.
Aseptic nontraumatic osteonecrosis of the femoral head is a disorder that can lead to femoral head collapse and the need for total hip replacement. Since osteonecrosis may be a disease of mesenchymal cells or bone cells, the possibility has been raised that bone marrow containing osteogenic precursors implanted into a necrotic lesion of the femoral head may be of benefit in the treatment of this condition. For this reason, we studied the implantation of autologous bone-marrow mononuclear cells in a necrotic lesion of the femoral head to determine the effect on the clinical symptoms and the stage and volume of osteonecrosis. ⋯ Implantation of autologous bone-marrow mononuclear cells appears to be a safe and effective treatment for early stages of osteonecrosis of the femoral head. Although the findings of this study are promising, their interpretation is limited because of the small number of patients and the short duration of follow-up. Further study is needed to confirm the results.

ReviewLigament reconstruction with or without tendon interposition to treat primary thumb carpometacarpal osteoarthritis. Surgical technique.
Trapezial excision with ligament reconstruction and trapezial excision with ligament reconstruction combined with tendon interposition have proven to be highly effective techniques for treating primary osteoarthritis of the thumb carpometacarpal joint. To determine whether tendon interposition and proximal migration of the thumb metacarpal affect the objective and subjective outcomes, we compared the long-term outcomes of these two procedures performed in similar patient groups. ⋯ Tendon interposition does not affect the outcome after the ligament reconstruction for the treatment of osteoarthritis of the thumb carpometacarpal joint. Furthermore, proximal migration of the thumb metacarpal does not appear to influence the functional outcome.
