Early Return to Play With Thumb Spica Gauntlet Casting for Ulnar Collateral Ligament Injuries Complicated by Adjacent Joint Dislocations in Collegiate Football Linemen

Background: Treatment of thumb ulnar collateral ligament (UCL) ruptures in elite athletes aims to restore thumb stability while minimizing lost playing time. Thus, surgical repair with early protected return to play in a thumb spica cast has been advocated. The purpose of this study was to document adjacent joint dislocations after primary surgical repair sustained during protected return to play with thumb spica casting in elite-level football players. Methods: Three Division I collegiate starting linemen sustaining adjacent joint dislocations in thumb spica casts following acute surgical repair of ipsilateral thumb UCL ruptures were retrospectively reviewed. Demographic data were recorded as well as the timeline for injury, treatment, and subsequent return to sport. Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores were obtained at final follow-up. Results: The mean time from thumb UCL injury to surgical repair was 8.7 days, and the mean return to sport was 13.3 days from surgery. There were 4 simple dislocations including 3 proximal interphalangeal (PIP) joints and 1 elbow. Each PIP dislocation was close reduced and treated with buddy straps with immediate return to play. The elbow dislocation was close reduced and splinted with return to play 22 days after injury. The mean QuickDASH score was 2.3 at 12 month follow-up. Conclusions: This report highlights that while thumb spica casting protects the surgically repaired thumb UCL and allows for earlier return to play, it risks placing additional stress upon adjacent joints and therefore adjacent injury. Appropriate counseling of the risks and benefits of this treatment strategy is essential.

Background: The number of ulnar collateral ligament (UCL) reconstructions in adolescent athletes has increased over the past 2 decades. Clinical results in this population have not been well studied. Purpose/Hypothesis: The purpose of this study was to evaluate the outcomes and return to sport after UCL reconstruction in a large group of adolescent baseball players. We hypothesized that excellent clinical outcomes and high rates of return to sport would be observed in this population at a minimum 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: We reviewed 140 adolescent (aged ≤19 years) baseball players who underwent UCL reconstruction with the American Sports Medicine Institute (ASMI) technique by a single surgeon. Medical records were reviewed for patient demographics, injury characteristics, operative details, and surgical complications. Patient-reported outcomes were assessed using the Conway scale, the Andrews-Timmerman (A-T) score, the Kerlan-Jobe Orthopaedic Clinic (KJOC) score, and a 0- to 100-point subjective scale for elbow function and satisfaction. Return to sporting activity was assessed using a custom-designed questionnaire. Results: The mean age at the time of surgery was 18.0 years (range, 13-19 years), and the mean follow-up was 57.9 months (range, 32.4-115.4 months). Over half (60%) of patients were high school athletes. The mean duration of symptoms before surgery was 6.9 months (range, 0.5-60.0 months). Partial tears were identified in 57.9% of patients, and 41.3% of patients had preoperative ulnar nerve symptoms. Graft type included the ipsilateral palmaris in 77.1% of patients. Concomitant procedures were performed in 25% of patients. Outcomes on the Conway scale were “excellent” in 86.4% of patients. The mean A-T and KJOC scores were 97.3 ± 6.1 and 85.2 ± 14.6, respectively. Mean patient satisfaction was 94.4. Overall, 97.8% of patients reported returning to sport at a mean of 11.6 months (range, 5-24 months), and 89.9% of patients returned to sport at the same level of competition or higher. A total of 11.6% of patients went on to play professional baseball. Conclusion: UCL reconstruction with the ASMI technique is an effective surgical option in adolescents, with excellent outcome scores. At a minimum of 2-year follow-up, nearly 90% of patients returned to their preinjury level of sport.

ImportanceTears of the ulnar collateral ligament (UCL) of the elbow occur predominantly as an overuse injury, most commonly affecting throwing athletes, particularly baseball players. UCL reconstruction (UCLR) has been described as an effective treatment modality in the short term.ObjectiveThe purpose of this study was to systematically review the evidence in the literature to ascertain the clinical outcomes, complication and revision rates in baseball players following UCLR of the elbow at a minimum of 48 months of follow-up.Evidence reviewTwo independent reviewers performed a search of the literature based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the EMBASE, PubMed and Scopus databases. Clinical studies were included if they reported outcomes of baseball players at a minimum of 48 months following UCLR.FindingsOur review included 8 studies including 1104 baseball players (1105 elbows) at mean 69.9 months (48–205) following UCLR. The majority of baseball players were pitchers (92.3%), with a mean age of 22.2 years (13–42). At final follow-up, the overall return to play (RTP) was 95.3%%, with 85.3% returning at pre-injury level. In addition, the mean reported Conway-Jobe score was 86.8%, the revision rate was 6.0% with postoperative neuropathy reported in 2.4% of patients. A total of 479 (43.4%) were professional baseball players, with an overall RTP rate of 97.5% and 82.3% managing to RTP at their pre-injury level. The mean number of career years following UCLR was 4.7 years (0–22).Conclusion and relevanceUCLR provides excellent patient-reported and clinical outcomes to patients at medium-term follow-up with low complication and revision rates. In addition, high rates of RTP at pre-injury level and career longevity were reported by baseball players following UCLR.Level of evidenceLevel IV; Systematic Review

Nerve Transposition

Background: Injury to the ulnar collateral ligament (UCL) leading to medial elbow instability and possible ulnar neuritis is common in overhead-throwing athletes. Treatment may require UCL reconstruction (UCLR) and concomitant ulnar nerve transposition (UNT) for those with preoperative ulnar neuritis. Purpose: To evaluate the return-to-play (RTP) rates, clinical outcomes, and rates of persistent ulnar neuritis after concomitant UCLR and UNT in a cohort of baseball players with confirmed preoperative ulnar neuritis. Study Design: Case series; Level of evidence, 4. Methods: Eligible patients were those who underwent concomitant UCLR and UNT at a single institution between January 2008 and June 2018 and who had a minimum of 2 years of follow-up. Additional inclusion criteria were athletes who identified as baseball players and who had a confirmed history of ulnar neuritis. Patients were contacted at a minimum of 2 years from surgery and assessed with the Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score, Andrew-Timmerman (A-T) Elbow Score, Mayo Elbow Performance Score (MEPS), Single Assessment Numeric Evaluation (SANE) score, and a custom RTP questionnaire. Results: Included were 22 male baseball players with a mean age of 18.9 ± 2.1 years (range, 16-25 years). The mean follow-up was 6.1 ± 2.4 years (range, 2.5-11.7 years). Preoperatively, all 22 patients reported ulnar nerve sensory symptoms, while 4 (18.2%) patients reported ulnar nerve motor symptoms. At the final follow-up, 7 (31.8%) patients reported persistent ulnar nerve sensory symptoms, while none of the patients reported persistent ulnar nerve motor symptoms. Overall, 16 (72.7%) players were able to return to competitive play at an average of 11.2 months. The mean postoperative patient-reported outcome scores for the KJOC Shoulder and Elbow Score, MEPS, A-T Elbow Score, and SANE score were 77.9 ± 20.9 (range, 14-100), 92.7 ± 12.7 (range, 45-100), 86.1 ± 17.1 (range, 30-100), and 85.5 ± 14.8 (range, 50-100), respectively. Conclusion: This study demonstrated that after concomitant UCLR and UNT for UCL insufficiency and associated ulnar neuritis, baseball players can expect reasonably high RTP rates and subjective outcomes; however, rates of persistent sensory ulnar neuritis can be as high as 30%.

Objectives: While results following ulnar collateral ligament (UCL) injury in baseball players has been well documented, results following UCL injury in gymnasts are not well documented. As such, the purpose of this study was to report the operative and non-operative outcomes of UCL injury in gymnasts. Methods: Gymnasts who underwent UCL injury treatment whether non-operative or operative at a single institution were evaluated at a minimum of 2 years post-operatively. Patients were assessed with Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score (KJOC), Mayo Elbow Performance Score (MEPS), Andrews-Timmerman (A-T) Elbow score, Quick Disabilities of the Arm, Shoulder and Hand (qDASH) score and a custom return to play survey. Results: There were 11 patients who met inclusion criteria and complete follow-up was available in 9 patients. Overall, 6 patients were treated operatively (4 UCL reconstructions (UCLR) and 2 UCL repairs) and 3 patients were treated non-operatively. One UCLR was performed after 2 months of failed non-operative management. All patients were female with a mean age of 16.1 (range, 12-20) and mean BMI of 24.46 (range 19.2-34.1) at time of surgery or initial visit. Average follow-up was 4.04 years. Overall, 66.7% of operative versus 100% of non-operative were able to RTP at an average of 7.5 and 7 months, respectively. One re-injury was reported in the non-operative group, which was a re-dislocation of the elbow unrelated to gymnastics and was ultimately treated non-operatively. The mean KJOC, MEPS, A-T and qDASH scores for the operative group were 70.0 (range, 48.5-89), 97.5 (range, 95-100), 90.8 (range, 75-100) and 24.6 (range, 22.7-29.5), respectively. The mean scores for the non-operative group were 75.9 (range, 61-91.2), 71.7 (range, 65-75), 71.7 (range, 55-80) and 34.1 (range, 22.7-40.9), respectively. Conclusions: Both operative and non-operative treatments can be offered as successful treatment options for UCL injuries in gymnasts. Further investigation is needed to determine the optimal management of UCL injuries in gymnasts.

Performance Statistics

Background: Ulnar collateral ligament (UCL) reconstruction is frequently performed on Major League Baseball (MLB) pitchers. Previous studies have investigated the effects of UCL reconstruction on fastball and curveball velocity, but no study to date has evaluated its effect on fastball accuracy or curveball movement among MLB pitchers. Purpose/Hypothesis: The primary purpose of this study was to determine the effects of UCL reconstruction on fastball accuracy, fastball velocity, and curveball movement in MLB pitchers. Our hypothesis was that MLB pitchers who underwent UCL reconstruction would return to their presurgery fastball velocity, fastball accuracy, and curveball movement. The secondary purpose of this study was to determine which factors, if any, were predictive of poor performance after UCL reconstruction. Study Design: Case-control study; Level of evidence, 3. Methods: MLB pitchers who underwent UCL reconstruction surgery between 2011 and 2012 were identified. Performance data including fastball velocity, fastball accuracy, and curveball movement were evaluated 1 year preoperatively and up to 3 years of play postoperatively. A repeated-measures analysis of variance with a Tukey-Kramer post hoc test was used to determine statistically significant changes in performance over time. Characteristic factors and presurgery performance statistics were compared between poor performers (>20% decrease in fastball accuracy) and non—poor performers. Results: We identified 56 pitchers with a total of 230,995 individual pitches for this study. After exclusion for lack of return to play (n = 14) and revision surgery (n = 3), 39 pitchers were included in the final analysis. The mean presurgery fastball pitch-to-target distance was 32.9 cm. There was a statistically significant decrease in fastball accuracy after reconstruction, which was present up to 3 years postoperatively ( P = .007). The mean presurgery fastball velocity of 91.82 mph did not significantly change after surgery ( P = .194). The mean presurgery curveball movement of 34.49 cm vertically and 5.89 cm horizontally also did not change significantly ( P = .937 and .161, respectively). Conclusion: Fastball accuracy among MLB pitchers significantly decreased after UCL reconstruction for up to 3 years postoperatively. There were no statistically significant differences in characteristic factors or presurgery performance statistics between poor and non--poor performers.

Significant Difference

Background: The modified Jobe and docking techniques are the 2 most commonly employed techniques for ulnar collateral ligament (UCL) reconstruction among overhead athletes. However, no study has directly compared these techniques performed by a single surgeon. Current comparisons of these techniques have relied solely on systematic reviews and biomechanical studies. Hypothesis: There will be no difference in outcomes or return to play between the modified Jobe and docking techniques in elbow UCL reconstruction surgery. Study Design: Cohort study; Level of evidence, 3. Methods: Twenty-five modified Jobe and 26 docking UCL-reconstructive surgical procedures were performed by a single surgeon, each with a minimum 2-year follow-up. Kerlan-Jobe Orthopaedic Clinic (KJOC) score, Conway Scale, years played, sex, handedness, sport, position, palmaris versus gracilis graft type, concomitant or future arm/shoulder injuries, and need for additional surgery were compared between the groups. Patients who underwent future shoulder or elbow surgery, no matter the cause, were included. Results: No difference was seen between the modified Jobe and docking reconstruction cases in regard to KJOC scores (mean ± SD: 78.4 ± 19.5 vs 72.0 ± 26.0, P = .44), Conway Scale (return to play, any level: 84% vs 82%, P = .61), years played (14.7 ± 6.2 vs 15.2 ± 5.8, P = .52), sex ( P = .67), handedness ( P ≥ .999), sport ( P = .44), position ( P = .60), level of competition ( P = .59), and future surgery (12% vs 4%, P = .35). Palmaris graft type had significantly higher KJOC scores than hamstring grafts (82.3 ± 20.0 vs 57.9 ± 21.2, P = .001). The mean follow-up was 6.1 years in the modified Jobe group and 7.3 years in the docking group (mean = 6.7, P = .47). Conclusion: The modified Jobe and docking techniques are both suitable surgical options for elbow UCL reconstruction. There was no statistically significant difference between the techniques in regard to return to play, KJOC score, or need for subsequent surgery at 6.7-year follow-up. This is the first direct clinical comparison of these 2 techniques by a single surgeon at midterm follow-up.

The Mean

Background: The rate of elbow medial ulnar collateral ligament (MUCL) injury and surgery continues to rise steadily. While authors have failed to reach a consensus on the optimal graft or anchor configuration for MUCL reconstruction, the vast majority of the literature is focused on the young, elite athlete population utilizing autograft. These studies may not be as applicable for the “weekend warrior” type of patient or for young kids playing on high school leagues or recreationally without the intent or aspiration to participate at an elite level. Purpose: To investigate the clinical outcomes and complication rates of MUCL reconstruction utilizing only allograft sources in nonelite athletes. Study Design: Case series; Level of evidence, 4. Methods: Patient records were retrospectively analyzed for individuals who underwent allograft MUCL reconstruction at a single institution between 2000 and 2016. A total of 25 patients met inclusion criteria as laborers or nonelite (not collegiate or professional) athletes with a minimum of 2 years of postoperative follow-up. A review of the medical records for the included patients was performed to determine survivorship free of reoperation, complications, and clinical outcomes with use of the Summary Outcome Determination (SOD) and Timmerman-Andrews scores. Statistical analysis included a Wilcoxon rank-sum test to compare continuous variables between groups with an alpha level set at .05 for significance. Subgroup analysis included comparing outcome scores based on the allograft type used. Results: Twenty-five patients met all inclusion and exclusion criteria. The mean time to follow-up was 91 months (range, 25-195 months), and the mean age at the time of surgery was 25 years (range, 12-65 years). There were no revision operations for recurrent instability. The mean SOD score was 9 (range, 5-10) at the most recent follow-up, and the Timmerman-Andrews scores averaged 97 (range, 80-100). Three patients underwent subsequent surgical procedures for ulnar neuropathy (n = 2) and contracture (n = 1), and 1 patient underwent surgical intervention for combined ulnar neuropathy and contracture. Conclusion: Allograft MUCL reconstruction in nonelite athletes demonstrates comparable functional scores with many previously reported autograft outcomes in elite athletes. These results may be informative for elbow surgeons who wish to avoid autograft morbidity in common laborers and nonelite athletes with MUCL incompetency.

A Prospective Study

Objectives: There has been a renewed interest in UCL repair in overhead athletes. This is largely due to greater understanding of UCL pathology, improvement in fixation technology and the extensive rehab required to return from UCL reconstruction. Initial data regarding UCL repair in overhead athletes was poor and therefore UCL repair was largely abandoned in favor of reconstruction. However, recent literature examining UCL repair with anchor only fixation demonstrated an excellent rate of return to play, reduced time to return to play and a low complication rate. Based on this promising data, we have developed a novel technique of UCL repair with internal brace augmentation that we have used in overhead throwing athletes. We performed a prospective study evaluating the outcomes of this procedure with respect to return to play, time to return to play, functional outcome score and complications. Methods: Overhead athletes undergoing UCL repair with internal brace augmentation were prospectively followed for a minimum of one year. Patients were carefully selected from those who would traditionally be considered for UCL reconstruction. Initially, patients were considered if they had an avulsion of the UCL with otherwise healthy UCL tissue and had a vested interest in shortened rehab. As the study progressed, interest in shortened rehab became a less stringent criteria. Demographic and operative data were collected at the time surgery. This data was compiled for both desciption and comparison between subgroups. Patients were then contacted 1 year postoperatively and assessed for return to play, time to return to play and KJOC scores. Complications were documented and patients having complications were detailed. Results: 66 overhead athletes underwent UCL repair with internal brace augmentation during the study period. 8 were lost to follow up, leaving 58 athletes included in the study. Average age at the time of surgery was 17.9 years old. There were 43 baseball pitchers, 8 baseball position players, 4 softball players, 2 football quaterbacks, and 1 javelin thrower. 96% (54/56) of those who desired to return to the same or higher level of competition were able to do so at an average time of 6.1 months (range 3.2-12 months). 65% of these were able to return in less than 6 months. Many of those who took longer than 6 months did so due to timing within the season. Average KJOC score was 90.2 at 1-year follow-up. 3 patients required return to the operating room, 2 of which were eventually able to return to their previous level of play. There was 1 late failure over 3 years from the index procedure. Comparative subgroup data is presented in table 1. Conclusion: UCL repair with internal brace augmentation is a viable option for overhead throwers with selected UCL pathology who wish to return to sport in a shorter time frame than allowed by traditional UCL reconstruction.

Background: Tearing and insufficiency of the ulnar collateral ligament (UCL) of the elbow result in valgus instability, which can lead to pain while throwing and decline in performance in overhead athletes. Purpose: To assess the clinical results of a modified UCL reconstruction technique using 1 bone hole in the ulna and 1 bone tunnel in the humerus in baseball players. Study Design: Case series; Level of evidence, 4. Methods: The inclusion criteria were medial elbow pain preventing effective playing, clinically medial elbow laxity, and magnetic resonance imaging results consistent with UCL injury. Patients who were engaged in other sports and in other positions in baseball except pitchers were excluded from this study. Our modified Tommy John procedure was performed via a muscle-splitting approach and an original single-bone-tunnel technique, using a suture anchor. After a minimum of 24 months, patients were evaluated using the Conway scale and the Timmerman-Andrews score. Results: Of 31 patients, 20 baseball pitchers (20 male: 5 high school, 5 collegiate, 8 nonprofessional, and 2 professional pitchers) were reviewed. The mean patient age at the time of operation was 21.9 years, and the mean postoperative follow-up period was 35.1 months (range, 24-66 months). The mean Timmerman-Andrews subjective score improved significantly from pre- to postoperatively (from 68.3 to 98.3; P < .05); the objective score also improved significantly (from 81.1 to 96.4; P = .01). No complications were detected at the latest follow-up. Overall, 19 patients were able to return to their preinjury level of sports or higher. Conclusion: UCL reconstruction with 1 bone hole in the ulna and 1 bone tunnel in the humerus demonstrated satisfactory results in baseball pitchers. Our modified technique was safe and achieved satisfactory clinical results, with a 95% rate of return to sports.

The Mean

Background: Medial ulnar collateral ligament (MUCL) repair has been proven to be effective in nonprofessional overhead-throwing athletes, with faster and higher rates of return to play (RTP) than the more traditional Tommy John reconstruction. Biomechanical studies and clinical data suggest that MUCL repair augmented with a collagen-coated internal brace may be an effective treatment option in this patient population. Purpose: To evaluate the functional outcomes of young nonprofessional athletes who underwent MUCL repair with internal brace augmentation for medial elbow instability. The hypothesis was that these patients will have high rates of RTP and improved functional outcomes. Study Design: Case series; Level of evidence, 4. Methods: Nonprofessional overhead athletes treated with MUCL repair with internal brace augmentation between 2015 and 2017 were prospectively evaluated for a minimum of 1 year. Preoperatively, all patients had evidence of medial elbow pain caused by MUCL insufficiency, as confirmed by signal changes on magnetic resonance imaging and valgus instability on arthroscopic examination. These findings did not allow them to participate in their chosen sport or profession, and each patient had failed nonoperative treatment. Postoperative outcomes were evaluated using the Overhead Athlete Shoulder and Elbow Score of the Kerlan-Jobe Orthopaedic Clinic. Complications were recorded and detailed. Results: A total of 40 nonprofessional overhead athletes were included in this study (35 men and 5 women; mean age, 17.8 years [range, 14-28 years]). The mean follow-up time was 23.8 months (range, 12-44 months). The mean postoperative Kerlan-Jobe Orthopaedic Clinic score was 92.6 (range, 64-100). Overall, 37 athletes (92.5%) returned to play or profession at the same level or higher at a mean time of 6.9 months (range, 2-12 months). Three patients did not RTP: 1 was limited by a concomitant medical diagnosis, and the other 2 chose not to resume athletics after the procedure but remained symptom free. Conclusion: In the nonprofessional athlete, primary MUCL repair with internal brace augmentation is a viable alternative to traditional repair techniques or reconstruction, allowing for a rapid RTP and promising functional outcomes.
