Distal Triceps Rupture with an Injury of the Medial Ulnar Collateral Ligament: a Result of a Fall Onto an Outstretched Arm - a Case Series.

Traumatic triceps tendon ruptures are rare and known to result in substantial disability unless appropriate surgical treatment is performed. A traumatic rupture can occur due to a fall onto the outstretched hand. Tearing of the triceps tendon results in a valgus load onto the elbow, which can lead to injuries to the radial head/neck and/or the ulnar collateral ligament. Hence, attention must be paid to associated pathologies after diagnosis of rupture to the distal triceps tendon. Our surgical procedure in these cases includes diagnostic arthroscopy to detect concomitant injuries. In the following, we present three cases where we performed an open suture bridge repair of the triceps tendon followed by suture repair of the ulnar collateral ligament. All patients recovered well and reported no elbow pain or limited range of motion. The ASES and Mayo Elbow Performance scores were 100 at the 1-year follow-up.

Three-dimensional evaluation of scapular morphology in primary glenohumeral arthritis, rotator cuff arthropathy, and asymptomatic shoulders.

BACKGROUND: Recently, the 3-dimensional (3D) morphology of the coracoacromial complex in nonpathologic shoulders has been described. The aim of this study was to evaluate and compare the coracoacromial complex in pathologic shoulders (glenohumeral osteoarthritis [GHOA] and cuff tear arthropathy [CTA]) and nonpathologic shoulders. METHODS: A 3D computed tomography reconstruction of 205 scapulae was performed (49 with GHOA, 48 with CTA, and 108 in normal shoulders [NL]). Subsequently, the center of the glenoid circle and several points at the coracoid, acromion, and glenoid were determined. The distances between these points and the rotation of the coracoacromial complex were calculated, and the acromion-glenoid angle was measured. RESULTS: The acromial overhang was significantly different between the NL (37 mm) and CTA (35 mm) groups (P = .045), as well as between the CTA and GHOA groups (33 mm) (P = .010). The acromion-glenoid angle showed a significant difference between the NL (mean, 50°) and GHOA (mean, 42°) groups (P < .001) and between the CTA (mean, 50°) and GHOA groups (P < .001). Furthermore, a significant difference was found in the acromial height, which was larger in the GHOA group (36 mm) than in the CTA group (30 mm) (P < .001) or NL group (30 mm) (P < .001). CONCLUSION: This 3D morphologic study showed that the acromial part of the complex was turned more posteriorly in both pathologic groups. Furthermore, we found the coracoacromial complex to be more cranial to the glenoid center in the GHOA group. Finally, a significant difference in the lateral overhang of the coracoacromial complex was observed between the 3 groups. The NL group had a larger overhang than the CTA group, and the CTA group in turn had a larger overhang than the GHOA group.

Medium-term outcome with contemporary mobile-bearing implants : results from a retrospective multicentre study.

Previous studies report good clinical outcomes with the initial mobile-bearing implant design in TKA. Nevertheless clinical data on the subject system are scant and information is lacking to fully appraise the safety and performance of the subject device. A population of 283 consecutive patients who received 307 primary Vanguard ROCC TKAs over a 5.5-year period was retrospectively assessed. At follow-up, Knee Society Scores, Forgotten Joint Scores and Knee injury and Osteoarthritis Outcome Scores were obtained, and patients underwent radiographic evaluation at 4.9 ± 1.0 years post-implantation. Survival analyses included the following endpoints : revision of the tibial or femoral component for any reason, and revision of any component for any reason. At a mean follow-up time of 5.0 (range, 3.0-8.2) years, 166 patients (183 TKAs) were available for clinical assessment. All postoperative clinical scores were deemed satisfactory. Survival with revision of the tibial and/or femoral component for any reason was 97.3% (95%, 94.5-98.7%) at 6 years. Radiolucent lines were observed in 32 (17.7%) out of 181 knees. The present study showed that the Vanguard ROCC system demonstrates favourable clinical outcome with satisfactory medium-term survival.
