The posterior transtriceps approach for intra-articular elbow diagnostics, definitely not forgotten.

BACKGROUND/AIMS: The elbow is among the most common joints that are aspirated and/or injected. An intra-articular approach should be a convenient and a safe procedure with minimal risk of complications. Several approaches to access the elbow joint have been outlined in the literature, but a comparative study is lacking. This study evaluates the technical feasibility of the lesser-performed posterior transtriceps approach with MR arthrography and compares it to the classic lateral radiocapitellar approach. PATIENTS AND METHODS: Using fluoroscopy guidance, MR arthrographies of the elbow were performed in 51 consecutive patients from 2006 to 2011. A classical lateral radiocapitellar approach was performed in 29 and a posterior transtriceps approach in 22 elbows. Studies were retrospectively reviewed with special attention to the extent of extra-articular contrast extravasation. This was a level IV diagnostic study. RESULTS: Contrast leakage occurred in 12 radiocapitellar approaches, which caused a diagnostic dilemma in one subject. There was only a minimal amount of contrast leakage in five subjects using the transtriceps approach and no diagnostic dilemmas occurred. Results show no significant differences between the approaches. No complications occurred in the posterior transtriceps group and all MR arthrographies were diagnostic. CONCLUSIONS: The posterior transtriceps approach is a technical feasible procedure, is easy to perform, and avoids a diagnostic dilemma in presumed injuries to the lateral collateral ligament complex. Our results show a tendency of even lesser amount of contrast leakage, further promoting a more widespread usage of the posterior transtriceps approach.

Long-term results after ulnar collateral ligament reconstruction of the elbow in European athletes with interference screw technique and triceps fascia autograft.

BACKGROUND: In the last decade, there has been increasing interest in medial ulnar collateral ligament (MUCL) reconstruction techniques for MUCL insufficiency of the elbow. All case series are based on American and Asian Athletes and use primarily a palmaris longus tendon or gracilis tendon as an autograft in reconstructions. A new technique is the interference screw fixation. Evidence that supports the use of this technique is mainly from controlled laboratory studies. The purpose was to evaluate the interference screw technique for MUCL reconstructions in a European, clinical setting, with a triceps tendon fascia autograft. METHODS: Twenty consecutive athletes with diagnosed MUCL insufficiency who underwent a MUCL reconstruction using the interference screw technique were reviewed retrospectively. Indications for reconstruction were medial elbow pain and/or instability caused by insufficiency of the MUCL that prevented the athlete from sport activity after a minimum of 3 months of conservative treatment. RESULTS: At a mean follow-up of 55 months (range, 36-94), the mean Mayo Elbow Performance Index (MEPI) score improved from 82 to 91 points (range, 80-100); P < .001. In the end, 6 patients (30%) quit the sport activities they were preoperatively participating in, all because of reasons unrelated to the MUCL reconstruction. There were excellent results on the Conway scale in 18 patients. CONCLUSION: Good results are reported based on the postoperative MEPI and Conway scores with clinically stable MUCL reconstructions without signs of break-out or fractures on radiographic follow-up. However, the dropout, even after successful reconstruction in European athletes, is high.

Nonsteroidal anti-inflammatory drugs and acetaminophen in the treatment of an acute muscle injury.

BACKGROUND: Nonsteroidal anti-inflammatory drugs are frequently used to treat muscle injuries in athletes. It is not known whether the anti-inflammatory effects of these drugs are important or whether their effectiveness is a result of their central analgesic effect. HYPOTHESIS: The effects of nonsteroidal anti-inflammatory drugs are no different than the effects of an analgesic (acetaminophen) without anti-inflammatory action in an experimental, acute muscle contusion model. STUDY DESIGN: Controlled animal study. METHODS: A standardized, unilateral, nonpenetrating injury was created to the tibialis anterior muscle of 96 adult male mice. Four treatment groups were used: group 1, placebo treatment; group 2, treatment with rofecoxib, a nonsteroidal anti-inflammatory drug with cyclooxygenase-2 selectivity, and treatment after the injury; group 3, rofecoxib treatment starting 24 hours before the injury; and group 4, acetaminophen treatment after the injury. The muscle and the contralateral normal muscle were evaluated at 2, 5, and 7 days after injury by grading of gait, wet weight as a measure of edema, and histologic evaluation. RESULTS: Group 1 had significantly more gait disturbances at day 2 than all other groups (P < .05). No differences were found at days 5 and 7. Wet weights showed an increase at day 2 in group 1 (P < .01). Again, no differences were found at days 5 and 7. Histology revealed similar inflammatory changes at day 2 in all groups, with regeneration of muscle fibers at days 5 and 7. CONCLUSIONS: The results indicate that rofecoxib as a nonsteroidal anti-inflammatory drug and acetaminophen as a non-nonsteroidal anti-inflammatory drug analgesic have similar effects. The lack of differences in wet weights and histology suggests that the anti-inflammatory effects of rofecoxib are not an important feature of its action. CLINICAL RELEVANCE: The routine use of nonsteroidal anti-inflammatory drugs in muscle injuries may need to be critically evaluated because low-cost and low-risk analgesics may be just as effective.
