INTRODUCTION: Ulnar collateral ligament (UCL) reconstructions are being performed with an increasing annual incidence. The purpose of this study was to evaluate trends in UCL surgery among recently trained orthopaedic surgeons. METHODS: The American Board of Orthopaedic Surgeons (ABOS) database was used to identify all UCL reconstructions from 2004 to 2013. Procedures were identified by Current Procedural Terminology (CPT) codes and verified by International Classification of Disease, Ninth Revision (ICD-9) codes...

BACKGROUND: There are excellent data supporting recommendations to prevent elbow injuries (osteochondritis dissecans [OCD] and ulnar collateral ligament [UCL] injuries), such as pitch count and pitch type in baseball, but anatomic risk factors have not been thoroughly examined. This study aimed to evaluate radiographic measurements in adolescents with elbow OCD lesions or UCL injuries and controls. METHODS: We retrospectively identified adolescent patients between 2011 and 2016 with isolated capitellum OCD, UCL tear, or normal elbows based on magnetic resonance imaging...

The ulnar collateral ligament (UCL) is the primary static restraint to valgus stress at the elbow. Since Jobe pioneered reconstruction in 1974, thousands of throwers have undergone UCL reconstruction, and good results have been achieved. The high-profile nature of the elite pitcher has brought this technique into the spotlight, and extensive research has been performed with new techniques emerging. The standard reconstruction, modified only slightly since Jobe's original description, remains the gold standard for treatment of UCL insufficiency...

The patient was an 18-year-old collegiate baseball pitcher who injured his right throwing elbow during an overhead slider pitch. As a part of a study, preinjury ultrasound images of the throwing arm were obtained 2 weeks prior to the injury. One day postinjury, repeat ultrasound imaging of the medial elbow was performed. The attending team physician ordered a magnetic resonance arthrogram 2 days after injury, which confirmed the presence of a complete tear of the ulnar collateral ligament.

BACKGROUND: Ulnar collateral ligament reconstruction (UCLR) has become a common procedure performed in overhead-throwing athletes of many athletic levels. PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether clinical outcomes and return-to-sport (RTS) rates differ among patients undergoing UCLR based on graft choice, surgical technique, athletic competition level, handedness, and treatment of the ulnar nerve. We hypothesized that no differences would exist in clinical outcomes or RTS rates between technique, graft choice, or other variables...

Medial elbow injuries in the throwing athlete are common and increasing in frequency. They occur due to repetitive supraphysiologic forces acting on the elbow during the overhead throw. Overuse and inadequate rest are salient risk factors for injury. Most athletes improve substantially with rest and nonoperative treatment, although some athletes may require surgical intervention to return to play. Because of advances in conservative and surgical treatments, outcomes after medial elbow injury have improved over time...

Thumb injuries are common in athletes and present a challenging opportunity for upper extremity physicians. Common injuries include metacarpal base fractures (Bennett and Rolando types), ulnar and radial collateral ligament injuries, dislocation of the carpometacarpal and metacarpophalangeal joints, and phalanx fractures. This review, although not exhaustive, highlights some of the most common thumb injuries in athletes. The treating physician must balance pressure from athletes, parents, coaches, and executives to expedite return to play with the long-term well-being of the athlete...

CONTEXT: Decreased performance in dynamic balance has previously been associated with a history of ulnar collateral ligament injury in baseball players. Previous research on dynamic balance in soccer players has shown that test performance depends on competition level. However, dynamic balance has yet to be examined in baseball players. OBJECTIVE: To understand normative values and determine differences in dynamic balance, as measured by the Lower Quarter Y-Balance Test, across competition levels in baseball players...

In adults, the oblique cord or chorda obliqua separates the origins of the flexor pollicis longus (FPL) and flexor digitorum profundus (FDP) muscles from the supinator muscle and elbow joint. This study examined the topographic anatomy of the oblique cord and related muscles in foetuses. Semiserial sections of five mid-term foetuses of gestational age (GA) 14-16 weeks and 12 late-stage foetuses of GA 28-30 weeks were histologically examined and three forearms at GA 30 weeks were macroscopically evaluated. Late-stage foetuses showed a fascial structure between the supinator and FDP muscles...

The treatment of elbow injuries can be challenging because of the complexity of both anatomy and pathology. We present a rare traumatic avulsion fracture of the supinator crest of the ulna in a 37-year-old patient. Conservative treatment in a long arm cast for four weeks led to satisfactory results. Reproduction of the fracture on a cadaveric elbow clarified that the avulsed fragment holds the insertion of the lateral ulnar collateral ligament (LUCL). The mechanism of trauma that causes this fracture is a posterolateral (sub) luxation of the elbow, which usually causes the LUCL to rupture, but in rare cases the insertion of this ligament can be avulsed...

BACKGROUND: Because medial elbow stability is essential for stiff elbow release, surgical techniques have been reported for reconstructing medial elbow stability. However, medial collateral ligament (MCL) defects, caused by inevitable detachment and resection performed for complete release, make the reconstruction more challenging. To our knowledge, no study has evaluated the outcomes after using a flexor-pronator fascia patch in medial elbow reconstruction for open release of stiff elbows...

Ulnar nerve (UN) injuries are a common complaint amongst overhead athletes. The UN is strained during periods of extreme valgus stress at the elbow, especially in the late-cocking and early acceleration phases of throwing. Although early ulnar collateral ligament (UCL) reconstruction techniques frequently included routine submuscular UN transposition, this is becoming less common with more modern techniques. We review the recent literature on the sites of UN compression, techniques to evaluate the UN nerve, and treatment of UN pathology in the overhead athlete...

Hand and wrist injuries in the high-level athlete are challenging because they may be underestimated by the patient, family, and team, and return to play may be longer than desired. The needs of the player and the team must be balanced with the long-term functional ramifications of the injury. Four common soft-tissue sports injuries are flexor digitorum profundus avulsion, flexor pulley rupture, extensor carpi ulnaris dislocation, and thumb metacarpophalangeal joint ulnar collateral ligament injury. For each of these injuries, the assessment, treatment, and considerations for return to play should be individualized on the basis of the patient, the sport, and the timing of the injury...

BACKGROUND: Double-strand lateral ulnar collateral ligament (LUCL) reconstruction is an effective treatment for posterolateral rotatory instability (PLRI) of the elbow, but anatomic landmarks for ulnar tunnel placement are often difficult to identify intraoperatively, which potentially can result in a nonanatomic LUCL reconstruction. This study investigated the effect of ulnar tunnel location on joint stability in double-strand LUCL reconstruction. METHODS: PLRI was artificially created in 7 cadaveric elbows, and double-strand LUCL reconstruction was performed...

Despite having many unique anatomic features relative to the other digits, the thumb has received little attention in the radiology literature. The thumb, with its opposable and prehensile abilities, enables fine manual dexterity. However, most radiologists have little familiarity with the structures that allow these dynamic movements, other than their recognition of the role of the ulnar collateral ligament in the setting of gamekeeper injury. High-resolution magnetic resonance (MR) imaging allows optimal assessment of the intricate soft-tissue anatomy of the thumb, which enables thumb flexion, extension, abduction, and adduction...
