Luxations of the fingers and midhand
Published in Peter Houpt, Hand Injuries in the Emergency Department, 2023
In the event of a distortion (partial rupture) of the ulnar collateral ligament: two weeks of plaster immobilization, followed by four weeks of tape treatment. A complete rupture of the ulnar collateral ligament is an indication for operative repair. If the rupture involves an avulsion without displacement four weeks immobilization will suffice.

Treatment options include the following: If the articular surfaces are intact (rare), then reconstruct the UCL with APL or a free FCR tendon graft.MCPJ arthrodesis ± IPJ arthrodesis if the joint surfaces are poor.Correction of adductors, release adductor pollicis and first dorsal interossei, ± Z-plasty web.

The differential diagnosis includes medial epicondylitis and a sublime tubercle fracture. Lateral ulnar collateral ligament forms part of the lateral ligament complex and presents with symptoms of lateral or postero-lateral elbow pain/instability.
High elasticity of the flexor carpi ulnaris and pronator teres muscles is associated with medial elbow injuries in youth baseball players

Although various theories regarding the contributing factors to medial elbow injuries in youth baseball players have been proposed, repetitive elbow valgus stresses during throwing has been previously demonstrated as contributing to these types of elbow injuries [3,5,6]. The forearm flexor-pronator muscles as well as the ulnar collateral ligament (UCL) contributes to elbow joint stability against valgus force during throwing [7–9]. Muscle elasticity is known to increase according to repeated muscle contraction and high external load [10–12]. A previous study reported that youth baseball players with medial elbow injuries had high elasticity in the pronator teres (PT) [13]. However, the relationships between the elasticities of the other forearm muscles and medial elbow injuries in youth baseball players are unknown. In cadaveric biomechanical studies, several authors have reported that the flexor digitorum superficialis (FDS) or flexor carpi ulnaris (FCU) were the major contributors to elbow valgus stability [7,8,14]. Accordingly, youth baseball players with medial elbow injuries may have high elasticities in these forearm muscles on account of repetitive elbow valgus stress. Moreover, a previous study indicated that the muscle elasticity increased with pain [15]. It is likely that youth baseball players with elbow pain have higher elasticity of the forearm muscles than those without elbow pain.

To our knowledge, there have been no studies demonstrating the effect of age on the ability to return to sport in MMA athletes. However, similar findings have been identified in other sports at various levels of competition. Two studies involving collegiate athletes found that following ACL injury and reconstruction, fourth and fifth year college athletes were less likely to return to the sport compared to younger athletes [12,13]. Similarly, a study of professional hockey players who sustained ACL tears found that players who were injured after turning 30 years of age were less likely to return to the sport for at least one full season [14]. Jack et al. demonstrated that for Major League Baseball position players undergoing ulnar collateral ligament reconstruction, there was an 89.4% return to sport rate for players under 30 years of age. For those older than 30, the rate decreased to 53.3% [15]. These studies are consistent with our finding that the mean age of the fighters who were unable to return to professional sport was 33 years, or roughly 3 years older than the athletes returning to the sport.
Comparison of outcome between nonoperative and operative treatment of medial epicondyle fractures

Louahem et al. (2010) argued that damage to the main medial stabilizer of the elbow, the medial collateral ligament, has far greater influence on elbow joint stability and outcome than actual fracture displacement and recommended surgery in patients with a positive valgus stress test, regardless of amount of fracture displacement. We did not routinely examine elbow stability in our patients at time of injury, an examination that often requires sedation. At follow-up there was no difference between the 2 treatment groups regarding stability of the elbow under valgus load. Nearly half of the nonoperatively treated children had an elbow dislocation, which was a clearly higher rate than one-fourth in the surgically treated children, thus one could argue that good results in the nonoperatively treated group could in part be due to an intact ulnar collateral ligament as suggested by Gottschalk et al. (2012).
