Recent studies have reported that massive rotator cuff tears do not heal as predictably as, and may have diminished clinical outcomes compared with, smaller rotator cuff tears. An improved understanding of the biologic degeneration and the biomechanical alterations of massive rotator cuff tears should provide better strategies to optimize outcomes. The approach to patients with massive rotator cuff tears requires careful assessment of the patient and the extent of rotator cuff degeneration to determine the appropriate treatment. ⋯ Even though the biomechanical constructs for rotator cuff repairs have been improved, the integrity of the repair still depends on biologic healing at the tendon-to-bone junction. There has been much interest in the development of a scaffold to bridge massive rotator cuff tears and adjuvant biologic modalities including growth factors and tenocyte-seeded scaffolds to augment tendon-to-bone healing. The treatment of rotator cuff disease has improved considerably, but massive rotator cuff tears continue to pose a challenging problem for orthopaedic surgeons.

Information regarding pelvic fractures sustained during snowboarding is scant. ⋯ Pelvic fractures resulting from snowboarding accidents included a higher proportion with isolated sacral fractures in the stable group and a lower prevalence of associated injuries in the unstable group compared with those resulting from other causes.

Revision ulnar collateral ligament reconstruction remains a challenging problem. The objective of this study was to biomechanically evaluate an ulnar collateral ligament reconstruction technique using a suspension button fixation technique that can be used even in the case of ulnar cortical bone loss. ⋯ Ulnar collateral ligament reconstruction using a suspension button fixation technique can be considered in the case of ulnar cortical bone loss in a primary or revision setting.

Men's intercollegiate lacrosse is played at a fast pace and with significant force. Glove protection is required. However, the thumb is at risk because of contact with opponents' sticks, the ball, other players, and the ground or artificial surface. ⋯ Men's intercollegiate lacrosse requires the use of gloves; nonetheless, injury rates of the thumb are significantly elevated in this sport compared with other gloved, stick-handling sports. Recommendations include the development of gloves with improved thumb protection.

Comparative Study
Skill level-specific differences in snowboarding-related injuries.
Snowboarding-related injuries have been associated with specific snowboarding skill levels, but differences in specific skill level have not been identified. ⋯ Prevalence of injury type, injury location, mechanism of injury, and percentage of protective gear use varied according to skill level, and the severity of the injury increased with increase in skill level. On the basis of our observations, we believe that snowboarding injury prevention strategies should be formulated according to skill level.
