The objective of this study was to clarify changes in the prevalence of capitellar OCD in young baseball players over a long-term period based on consistent criteria in Tokushima, Japan between 2006 and 2020.<h4>Methods</h4>The number of players who underwent screening and the discovery rate of capitellar OCD during the study period were investigated. School grade and radiographic stage were also evaluated.<h4>Results</h4>The confirmation rate was significantly higher when ultrasonographic screening was performed than when screening was based on physical findings (65.8% vs. 1.9%, <i>P</i> < .001). The overall incidence of OCD in elementary school players based on ultrasonographic screening was 1.4% during the 10-year study period. Twenty-one (10.8%) of the 195 players identified to have OCD had experienced lateral elbow pain. When classified radiographically, the lesion was stage I in 73.3% of cases, stage II in 24.1%, and stage III in 2.6%. No cases of OCD were diagnosed before the fourth grade. The prevalence rates increased gradually from the fourth grade to the sixth grade.<h4>Conclusion</h4>Ultrasonographic screening could be more effective for detecting capitellar OCD than screening based on physical findings. The overall prevalence of OCD among elementary school players was 1.4% over 10 years. The prevalence rates increased gradually from the fourth grade onwards.

Although an improved version of PiG has been developed, called the Conventional Gait Model 2 (CGM2), there is limited evidence on its between-day reliability for running.<h4>Research question</h4>What is the between-day intraclass correlation coefficient (ICC3,k) and minimum detectable change (MDC) of lower limb kinematics and kinetics for CGM2 during running and does reliability differ between CGM2 and PiG.<h4>Methods</h4>Twenty-three healthy participants performed running at a comfortable speed in two identical test sessions at least 5 days apart. Lower limb kinematic and kinetic data in the three planes of motion were calculated using CGM2 and PiG. The ICC and MDC were calculated for the kinematic and kinetic parameters at initial contact and peak during the stance phase of running.<h4>Results</h4>CGM2 kinematics showed good-to-excellent reliability (ICC: 0.75-0.93), except for hip extension and ankle internal rotation, and less than 5° MDC (1.8°-4.9°) of the coronal and sagittal planes, except for hip extension. PiG showed poor-to-moderate reliability (ICC: -0.15 to 0.72) in the coronal and transverse planes and greater than 5° MDC (5.0°-21.8°), except for knee extension, adduction, and ankle dorsiflexion. CGM2 showed good-to-excellent reliability for peak kinetics (ICC: 0.75-0.97), except for hip internal rotation and knee extension. The ICC and MDC were higher for CGM2 than PiG, with significant differences in the coronal plane of the hip and knee joints and transverse plane of the hip joint in kinematics and in the sagittal and coronal plane of the hip and knee joints in kinetics.<h4>Significance</h4>The between-day reliability of CGM2 was mostly good to excellent for lower limb kinematics and kinetics during running. We believe that CGM2 can more accurately assess kinematic differences between the coronal and transverse planes than the PiG.

Inclusion criteria were patients with medium or larger-sized tears and with a minimum of 6 months' follow-up. Patients with a partial repair were excluded. Intraoperative repair tension was measured according to Davidson's method. Correlation of repair tension with preoperative factors was evaluated with Pearson and Spearman correlation coefficient tests. Logistic regression analysis was performed on intraoperative factors, including repair tension, to identify independent predictors of retear after ARCR. Receiver operating characteristic (ROC) curve was used to determine the cutoff value of repair tension for retear.<h4>Results</h4>One-hundred twenty patients met the inclusion criteria. Mean repair tension was 26.6 ± 12.6 N, and retear was found in 29 shoulders (24.2%). Among the preoperative factors, tear size in the mediolateral (P < .001) and anteroposterior (P < .001) directions, DeOrio and Cofield's classification (P <0.001), geometric classification (P <.001), and fatty infiltration of supraspinatus (P = .006) and infraspinatus (P = .003) were significantly correlated with repair tension. However, multivariable logistic regression analysis identified only tear size in the mediolateral direction as an independent predictor of repair tension (P = .036). Logistic regression analysis showed that repair tension (P = .02) and geometric classification (P < .001) are significant factors affecting rotator cuff integrity after ARCR. ROC curve analysis showed the cutoff value of repair tension of large to massive tears for retear to be 35.6 N.<h4>Conclusion</h4>This study demonstrated that intraoperative repair tension is strongly correlated with tear size in the mediolateral direction based on preoperative magnetic resonance imaging and that measuring tension during ARCR is effective for predicting rotator cuff integrity after ARCR.<h4>Level of evidence</h4>Level IV, prognostic study.

However, few studies have compared the effectiveness of limiting the pitch count versus the limiting the number of innings pitched in terms of elbow injuries.<h4>Hypothesis</h4>We hypothesized that, compared with inning limits, pitch count limits would lead to greater decreases in elbow pain, range of motion deficits, positive moving valgus stress test results, and the risk of capitellar osteochondritis dissecans (OCD).<h4>Study design</h4>Cohort study; Level of evidence, 3.<h4>Methods</h4>This study retrospectively reviewed baseball pitchers aged 8 to 12 years in 2017 and 2018. Inning and pitch count limits in games were set to a daily maximum of 7 innings in 2017 and 70 pitches in 2018. Elbow pain, range of motion, and moving valgus stress test results were evaluated. The presence of capitellar OCD was assessed on ultrasonographic and radiographic images.<h4>Results</h4>A total of 352 pitchers in 2017 and 367 pitchers in 2018 participated. The mean pitch count per game was lower in the pitch count limit (CL) group (52.5 ± 16.0) than in the inning limit (IL) group (98.2 ± 19.5) (<i>P</i> < .001). Compared with the IL group, the CL group had significantly lower rates of elbow pain (40.9% vs 31.9%, respectively; <i>P</i> = .01) and reduced flexion (19.0% vs 10.6%, respectively; <i>P</i> = .001). Multivariate analysis revealed a significant association between elbow pain and age in both the IL and the CL groups (<i>P</i> < .0001 and <i>P</i> = .02, respectively) and between OCD and elbow pain in the CL group (<i>P</i> = .04).<h4>Conclusion</h4>A pitch count limit of ≤70 pitches per day for baseball pitchers ≤12 years could be more protective against elbow pain and reduced flexion than a limit of ≤7 innings per day, but it may not be effective for reducing the risk of capitellar OCD.

Inclusion criteria were a medium or large-sized tear and a minimum of 1-year follow-up. Clinical outcome measures included range of motion (ROM) and the Japanese Orthopaedic Association (JOA) and University of California, Los Angeles (UCLA) scores preoperatively and at final follow-up. Rotator cuff retear was evaluated with magnetic resonance imaging at 3 months post-surgery and final follow-up. Diabetic patients with poor control were pre-operatively hospitalized for intensive diabetic control.<h4>Results</h4>Our inclusion criteria were met by 30 diabetic patients and 126 non-diabetic patients. Demographic data were not significantly different between the groups, except body mass index (p = 0.021). Preoperative JOA and UCLA scores of the diabetic patients were significantly lower than those of the non-diabetic patients (p < 0.001, and p = 0.006, respectively); however, the scores at final follow-up were not different. ROM was significantly restricted in the diabetic patients before surgery (forward flexion, abduction, internal rotation: p < 0.001, external rotation: p = 0.035), but at the final follow-up, there was no significant difference except for internal rotation (p = 0.005). The retear rate in diabetic patients (23.3%) was not significantly different from that in non-diabetic patients (15.1%).<h4>Conclusions</h4>Diabetic patients who had good perioperative glycemic control showed clinical and structural outcomes comparable to non-diabetic patients after ARCR. Intensive perioperative glycemic control and patient education are recommended for preoperative uncontrolled diabetic patients.<h4>Level of evidence</h4>III.

We encountered a case of an accessory bone in the foot in the distal portion of the tarsal navicular and the proximal portion of the intermediate cuneiform, namely an os intercuneiform. The patient presented with a history of pain on the dorsal aspect of the left foot, with tenderness and swelling. Perioperative findings revealed a synfibrotic connection between the accessory bone and the navicular and intermediate cuneiform. After unsuccessful conservative treatment, the accessory bone was excised, leading to postoperative symptomatic relief.

Vertebral bone bruise (VBB) in children commonly occurs following a fall from a height, and more than one vertebral body may be affected. We encountered 6 children each with a single VBB caused by mild physical activity. All the children had tenderness on the corresponding spinous process with no neurologic findings. Magnetic resonance imaging (MRI) showed typical findings of VBB in all cases. The children were treated conservatively with a soft thoracolumbar brace and instructed to rest with no physical activity for a month. At follow-up 1 month later, the back pain had diminished, and the signal changes seen on MRI had disappeared in all cases. We conclude that mild physical activity may be a cause of VBB in children and good clinical results can be achieved by using a soft thoracolumbar brace and rest.

Patients were eligible for participation if they had undergone surgery at least 2 years earlier and excluded if they had arthritis, loose bodies, osteochondritis dissecans, ulnar collateral ligament tear, flexor/pronator injuries or medial epicondylitis, or nerve problems. Patients were also excluded if they had undergone prior elbow surgery, were younger than 13 years, or were older than 19 years. Arthroscopic treatment included debridement of posteromedial synovitis, fragment removal, and olecranon spur excision. At a mean follow-up of 26.7 (range 24-42) months, patients were evaluated based on a questionnaire, examination, and the previously reported elbow outcome score.<h4>Results</h4>This retrospective study involved 15 male patients, comprising 6 pitchers, 3 catchers, and 6 fielders, of mean age 15.7 (range 14-17) years. Mean time from onset of symptoms to surgery was 4.9 (range 3-18) months. Intraoperative findings included posteromedial synovitis and olecranon spurs in all patients and fragments in 10. The elbow outcome score was considered excellent in 11 patients and good in 2, with a mean score of 92 points (maximum 100 points). The mean postoperative range of motion at the elbow was 5° to 139.7° of flexion. All patients were able to return to their previous level of play after an average of 3.4 (range 2.5-4.5) months. No patient developed medial instability that later required reconstructive surgery.<h4>Conclusions</h4>Arthroscopic debridement, excision of the olecranon spur, and removal of fragments yield reliable subjective and objective results and allow a return to baseball in adolescent patients.<h4>Level of evidence</h4>Level IV, therapeutic case series.

Subjects classified as grade 1a or 1b showed irregularities of the subchondral bone surface and were investigated radiographically for OCD. All players continued to throw and were re-examined by ultrasonography after 1 and 2 years.<h4>Results</h4>At the first examination, 11/321 (3.4%) had irregularities at the subchondral surface of the capitellum [grade 1a in 7/321 (2.2%); grade 1b in 4/321 (1.2%)]. The seven players with grade 1a showed no evidence of OCD or Panner's disease on radiography and were reclassified as grade 0 at the 2-year follow-up. All four players with grade 1b were reclassified as grade 0 at follow-up 1 and 2 years later.<h4>Conclusion</h4>Subchondral bone surface irregularities of the capitellum on ultrasonography in children under the age of 10 years may not be indicative of disease, but rather represent variation of ossification during normal development.

A 21-year-old woman who was high-level college softball player presented with a 6-month history of low back pain that had been treated unsuccessfully by medication at local clinics. There was tenderness in the left paravertebral muscle at the lower lumbar level. X-ray and computed tomography revealed congenital scoliosis and an L6 hemivertebra. Short tau inversion recovery magnetic resonance imaging showed a fluid collection at the left L6-S1 facet joint. We performed a diagnostic facet injection, consisting of 1% lidocaine and steroids, that was infiltrated into the left facet joint at L6-S1. Her persistent low back pain disappeared immediately after the facet block. We diagnosed left-sided facet arthritis at L6-S1. Due to her multiple congenital anomalies, excessive loading occurred at the facet joint. Therefore, we opted for conservative management, including mobilization of the thoracic spine and stretching of hamstrings and quadriceps. This case report underscores the importance of accurate diagnosis of low back pain and of the diagnostic utility of short tau inversion recovery magnetic resonance imaging and lumbar facet block in young athletes with chronic spinal pain.
