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%.

Background: No study has specifically evaluated how ulnar neuritis and ulnar nerve transposition affect outcomes in baseball players undergoing ulnar collateral ligament (UCL) reconstruction (UCLR). Purpose: To evaluate the effects of ulnar neuritis and ulnar nerve transposition in baseball pitchers undergoing UCLR in regard to return to sport, time to return to sport, and need for revision or additional surgery. Study Design: Cohort study; Level of evidence, 3. Methods: At a single institution, all consecutive baseball pitchers undergoing UCLR between 2002 and 2015 were identified. Ulnar neuritis was diagnosed preoperatively by the following criteria: ulnar nerve symptoms, Tinel sign at the elbow, symptomatic subluxation, and numbness/paresthesia in an ulnar nerve distribution of the hand. The primary outcome of the study was return to sport. The secondary outcomes of the study were time to return to sport, length of playing career, and revision or additional surgery. Results: A total of 578 UCLRs were performed in baseball players; of these, 500 UCLRs were performed in pitchers. Ulnar neuritis was diagnosed in 97 (19.4%) baseball pitchers presenting with UCL injury. There were no significant differences in patient characteristics or surgical techniques performed for reconstruction between baseball pitchers with and without ulnar neuritis. In review of injury characteristics, ulnar neuritis was significantly more likely to be diagnosed in pitchers with an acute onset of UCL injury ( P = .03). Transposition of the ulnar nerve was more commonly performed in players with ulnar neuritis (47%) versus those without ulnar neuritis (10%; P = .0001). The players who had ulnar neuritis and underwent UCLR had a significantly lower odds of returning to sport (odds ratio, 0.45; P = .04); however, no significant difference was found for time to return to sport and length of playing career for those with and without ulnar neuritis ( P = .38 and .51, respectively). Conclusion: The study suggests that ulnar neuritis, when present preoperatively in baseball pitchers undergoing UCLR, may adversely affect their ability to return to sport, whereas ulnar nerve transposition at the time of UCLR does not alter the ability to return to sport.

Nerve Transposition

Objectives: Injury to the ulnar collateral ligament (UCL)—leading to medial elbow instability and concomitant ulnar neuropathy symptoms—is common in the overhead throwing athlete secondary to the repetitive stress that these individuals place on the elbow during the throwing motion. Treatment customarily involves UCL reconstruction (UCLR) and for those with preoperative ulnar neuropathy symptoms, concomitant ulnar nerve transposition (UNT) may also be warranted. The purpose of this study was to evaluate the return to play rates, clinical outcomes and more specifically rates of persistent ulnar nerve symptoms after concomitant UCLR and UNT in a cohort of baseball players with confirmed preoperative ulnar neuropathy symptoms. Methods: Patients who underwent concomitant UCLR and UNT from January 2008 to June 2018 were identified at one institution with a minimum of 2 years of follow-up. Additional inclusion criteria included athletes who identified as baseball players with a confirmed history of ulnar neuropathy symptoms. Exclusion criteria included patients who had any other concomitant open procedures at the time of surgery. After identifying the cohort, patients were contacted via phone to complete a Kerlan-Jobe Orthopedic Clinic Shoulder and Elbow Score (KJOC), Andrews-Timmerman (AT) Elbow Score, Mayo Elbow Performance Score (MEPS), Single Assessment Numeric Evaluation (SANE) score and a custom return to play questionnaire. Evidence for preoperative and postoperative ulnar nerve symptoms was elicited within the custom survey and corroborated with the provider’s clinical notes. Sensory ulnar nerve symptoms were defined as having numbness and/or tingling sensations in the 5th and ulnar half of the 4th fingers. Motor ulnar nerve symptoms were defined as either exhibiting 1st dorsal interosseous muscle weakness by inability to maintain finger abduction resistance, ulnar-sided hand grip weakness of inability to control precise movement of the 5th digit. Results: During this time period, a total of 22 male baseball players underwent concomitant UCLR and UNT at a mean age of 18.9+/-2.1 years (range, 16-25). The mean follow-up was 6.1+/-2.4 years (range, 2.5-11.7 years). The cohort consisted of 15 pitchers and 7 position players. In total, 7 players competed in high school and 15 competed in college. Preoperatively, all 22 patients reported ulnar nerve sensory symptoms while only 4 (18.2%) patients reported ulnar nerve motor symptoms. Overall, 16 (72.3%) players were able to return to competitive play at an average of 11.2 months. Of the 6 that failed to return to play after surgery, 3 reported that persistent elbow symptoms were the reason for not returning to play while the other 3 reported losing the desire to return to play. At final follow-up, 7 (31.8%) patients reported of persistent sensory ulnar nerve sensory symptoms while 1 (4.5%) of these patients additionally reported persistent ulnar nerve motor symptoms. The mean postoperative patient reported outcome scores were as follows: KJOC: 77.9+/-20.9 (range, 14-100); MEPS: 92.7+/-12.7 (range, 45-100); AT Elbow Score: 86.1+/-17.1 (range, 30-100); SANE score: 85.5+/-14.8 (range, 50-100). Conclusions: While patient-reported outcome scores and return to play rates are reasonably high, this study demonstrates that following concomitant UCL reconstruction and ulnar nerve transposition for UCL insufficiency and associated ulnar neuropathy, rates of persistent ulnar neuropathy symptoms are persistently present in over 30% of patients. Currently, handling of the ulnar nerve in the setting of UCL insufficiency is debated and thus further investigation is warranted to optimize outcomes for this group of patients.

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

Background: Recent innovative techniques have led to renewed interest in ulnar collateral ligament (UCL) repair. Although early outcome data regarding the clinical outcome of overhead athletes undergoing UCL repair with augmentation have been encouraging, long-term data are still needed to evaluate both the appropriate indications and success rate for this procedure. Purpose: To describe and evaluate the acute complications seen in a large cohort of patients who underwent UCL repair with internal brace augmentation at a single institution. Study Design: Case series; Level of evidence, 4. Methods: We performed a retrospective chart review of a prospectively collected database, consisting of all patients who underwent UCL repair with internal brace augmentation utilizing a collagen-dipped FiberTape at our institution from August 2013 to January 2020. Patient characteristics, injury setting, side of surgery, and concomitant ulnar nerve transposition procedures were recorded. Early complications of UCL repair (within 6 months of the procedure) were evaluated and characterized as either minor or major, depending on whether the patient required a return to the operating room. Results: Of the 353 patients who underwent UCL repair at our institution with a minimum of 6-month follow-up, 84.7% (299/353) reported no complications, 11.9% (42/353) reported minor complications—including ulnar nerve paresthesia, postoperative medial elbow pain, and postoperative superficial wound complications—and 3.4% (12/353) required a return to the operating room because of a major complication requiring ulnar nerve exploration/debridement, primary ulnar nerve transposition, or heterotopic ossification excision. Conclusion: The low major complication rate identified in this study further validates the efficacy of the UCL repair with the internal bracing augmentation technique. Longer term follow-up data are needed to more adequately assess the outcomes and durability of this procedure.

Background: The modified Jobe and docking techniques are the most common techniques used for elbow ulnar collateral ligament (UCL) reconstruction. Previous systematic reviews have suggested that the docking technique results in superior outcomes as compared with the Jobe (figure-of-8) technique. However, these included results from earlier studies in which the flexor-pronator mass (FPM) was detached and an obligatory submuscular ulnar nerve transposition was performed. Purpose/Hypothesis: The purpose was to compare the outcomes and return-to-play (RTP) time between the docking and figure-of-8 techniques for UCL reconstruction. We hypothesized that there would be no significant difference in the proportion of excellent outcomes between techniques when the FPM was preserved and no obligatory submuscular ulnar nerve transposition was performed. We also hypothesized that there would be no significant difference in RTP time between techniques. Study Design: Systematic review and meta-analysis. Methods: This study was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. In the primary analysis, techniques were compared in random effects models by using the restricted maximum likelihood method, with weighted effect sizes calculated as the Freeman-Tukey double-arcsine transformed proportion of excellent outcomes for variance stabilization and with summary effects estimated from the inverse double-arcsine transformation per the harmonic mean of the sample sizes. Mean RTP times for techniques were compared in a separate model. Results: There were 21 eligible articles identified, with results for 1842 UCL reconstructions (n = 320, docking; n = 1466, figure-of-8). Without controlling for the effects of flexor-pronator detachment and submuscular ulnar nerve transposition, a significantly larger proportion of excellent outcomes was observed with docking reconstruction (86.58%; 95% CI, 80.42%-91.85%) than with figure-of-8 reconstruction (76.76%; 95% CI, 69.65%-83.25%; P = .031); however, there was no significant difference between techniques when controlling for FPM preservation or detachment with submuscular nerve transposition ( P = .139). There was no significant difference between techniques in time to return to sports ( P = .729), although no reconstructions with FPM detachment and submuscular ulnar nerve transposition were available for RTP time analysis. Conclusion: There was no significant difference in the proportion of excellent Conway Scale outcomes or RTP time between the docking and modified Jobe techniques for UCL reconstruction when the FPM was preserved and routine submuscular ulnar nerve transposition was not performed.

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.

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: While ulnar collateral ligament reconstruction (UCLR) of the elbow is an increasingly commonly performed procedure with excellent results reported in the published literature, less attention has been paid to specifically on the characterization of postoperative ulnar nerve complications, and it is unclear what operative strategies may influence the likelihood of these complications. Purpose: The purpose of this study is to examine the prevalence and type of ulnar nerve complications after UCLR of the elbow based on the entirety of previously published outcomes in the English literature. In addition, this study examined how the rate of ulnar nerve complications varied as a function of surgical exposures, graft fixation techniques, and ulnar nerve management strategies. Study Design: Systematic review and meta-analysis. Methods: A systematic review of the literature was completed using the MEDLINE, PubMed, and Ovid databases. UCLR case series that contained complications data were included. Ulnar neuropathy was defined as any symptoms or objective sensory and/or motor deficit(s) after surgery, including resolved transient symptoms. Meta-analysis of the pooled data was completed. Results: Seventeen articles (n = 1518 cases) met the inclusion criteria, all retrospective cohort studies. The mean prevalence of postoperative ulnar neuropathy was 12.0% overall after any UCLR procedure at a mean follow-up of 3.3 years, and 0.8% of cases required reoperation to address ulnar neuropathy. There were no cases of intraoperative ulnar nerve injury reported. The surgical approach associated with the highest rate of neuropathy was detachment of flexor pronator mass (FPM) (21.9%) versus muscle retraction (15.9%) and muscle splitting (3.9%). The fixation technique associated with the highest rate of neuropathy was the modified Jobe (16.9%) versus DANE TJ (9.1%), figure-of-8 (9.0%), interference screw (5.0%), docking technique (3.3%), hybrid suture anchor-bone tunnel (2.9%), and modified docking (2.5%). Concomitant ulnar nerve transposition was associated with a higher neuropathy rate (16.1%) compared with no handling of the ulnar nerve (3.9%). Among cases with concomitant transposition performed, submuscular transposition resulted in a higher rate of reoperation for ulnar neuropathy (12.7%) compared with subcutaneous transposition (0.0%). Conclusion: Despite a perception that UCLR has minimal morbidity, a review of all published literature revealed that 12.0% of UCLR surgeries result in postoperative ulnar nerve complications. UCLR techniques associated with the highest rates of neuropathy were detachment of the FPM, modified Jobe fixation, and concomitant ulnar nerve transposition, although it remains unclear whether there is a causal relationship between these factors and subsequent development of postoperative ulnar neuropathy due to limitations in the current body of published literature.
