Abstract

Objective: Restoration of ulnar elbow stability in cases of posttraumatic and chronic ulnar ligament instability., Indications: Symptomatic therapy-resistant ulnar ligament instability of the elbow., Contraindications: Arthrofibrosis and high-grade elbow arthrosis., Surgical Technique: Anatomical reconstruction of the ulnar collateral ligament (UCL) with autologous tendon graft (tendons of the palmaris longus muscle and gracilis muscle) in implant-free docking technique., Postoperative Management: A cast for 1 week, then 5 weeks orthesis with limitation of complete extension and flexion; full weight bearing after 3 months., Results: After 2 years 90% of the patients are able to return at an equal level of activity. The overall complication rate is 10.4%. The most common complication is ulnar nerve neurapraxia in 7.8% of the patients.

Abstract

Elbow ulnar collateral ligament reconstruction (UCLR) in Major League Baseball players using either a docking technique or a modified Jobe technique (modified to avoid flexor-pronator detachment) is effective treatment in experienced hands. The study of UCLR in Major League Baseball players requires recording and reporting of the actual number of athletes treated by individual surgeons using different techniques, to determine practice patterns. Absent these data, and with poor response rate by the solicited physicians (41%), survey results may be misleading. In addition, although transient ulnar neuritis may occur during UCLR, permanent ulnar neuropathy is exceedingly rare., (Copyright © 2016. Published by Elsevier Inc.)

Abstract

Chronic posterolateral rotatory instability (PLRI) of the elbow is the result of an insufficiency of the lateral collateral ligament (LCL). Lateral ulnar collateral ligament (LUCL) reconstruction represents a well-established treatment method for PLRI. However, recurrent instability remains a problem.The goal of this in-vitro study was to evaluate the posterolateral rotatory stability of the intact elbow, after sectioning of the LCL and after LUCL reconstruction with a triceps tendon autograft and double BicepsButton(TM) fixation.Posterolateral rotatory stability of 6 fresh-frozen elbow specimens at a torque of 3 Nm was analyzed at 0, 45, 90 and 120° of flexion for the intact LCL, after sectioning of the LCL and after LUCL reconstruction. Moreover, cyclic loading (1000 cycles) of the intact specimens and after LUCL reconstruction was performed.The intact LCL and the LUCL reconstruction provided equal primary stability (0.250 ≤ p ≤ 0.888). Sectioning of the LCL significantly increased PLRI (p 0.001). The stability of the intact specimens and after LUCL reconstruction did not differ after cyclic loading (p = 0.218). During cyclic loading, posterolateral rotation increased significantly more after LUCL reconstruction (3.2 ± 0.8°) when compared to the native LCL (2.0 ± 0.7°, p = 0.020).LUCL reconstruction with BicepsButton(TM) fixation provides comparable stability to the native LCL. Further clinical results are necessary to evaluate whether this technique can decrease the complication rate.
