Epidemiology of the Injuries Sustained by Elite Spanish under-18 and under-20 Rugby Players.

This study examines the injuries suffered by players (n=166) of the Spanish national men's under-18 and under-20 rugby teams between 2015 and 2017, and identifies the actions involved in their occurrence. All injuries (total n=78) sustained during matches and training were recorded as recommended by World Rugby, and injury incidence rates per 1000 player-hours (ph) calculated for both types of activity. Injuries occurred more commonly during matches than during training (incidence 105.3 [95% CI: 78.7-131.9] per 1000 [ph] of match play, vs 1.16 [95% CI: 0.69-1.62] per 1000 ph of training), and most days absent per 1000 ph during matches with<3 days rest since the previous match (4209.2 [95% CI: 3516.2-4902.1] per 1000 ph of match play, vs 1947.4 [95% CI: 1511.8-2382.9] per 1000 ph of match play in matches with>3 days rest). These results provide information that may be useful in the development of strategies aimed at reducing the incidence of injuries.

"Y" Graft Double Bundle Anterior Cruciate Ligament Reconstruction.

Single-bundle (SB) anterior cruciate ligament (ACL) reconstruction has been a standard procedure. However, residual rotary instability in approximately 20% of the cases (irrespective of the graft choice and the surgical technique) forces the surgeon to improve the biomechanical quality of the reconstruction. In parallel, adjustable suspensory fixation (ASF) devices have arisen. Biomechanics has defined (both anatomical and functional) the anteromedial (AM) and posterolateral (PL) bundles that work synergistically. In the unsymmetrical "anatomic" SB ACL reconstruction, the distribution of the ACL graft fibers (for AM or PL behavior) is not under the control of the surgeon. Furthermore, different sizes of the original footprints (depending on height) suggest the need to customize the graft footprint. This customization is only possible if distances are measured during surgical procedures. We present an inside-out technique for DB ACL reconstruction ("all-inside" also possible). Semitendinosus is folded to obtain a Y-shaped trifurcate configuration graft, distributing their bundles in two different areas. Used as measuring instruments, we used the "offset" guides as measuring instruments, allowing the surgeon to know the distance between the centers of the AM and PL tunnels. It may be carried out by means of common "offset" guides and any marketed ASF devices, while generating customized footprints. CLASSIFICATION: I: knee; II: ACL.

Epidemiology of Injuries Sustained by Elite Under-18 Rugby Players.

CONTEXT: The physical nature of rugby is responsible for the high incidence of injuries, but no researchers have examined the epidemiology of injuries sustained by elite under-18 rugby players. OBJECTIVE: To investigate the incidence of injuries sustained by players on the Spanish national under-18 rugby team during their participation in 4 European championships (2014-2017) and the types of play in which they occurred. DESIGN: Cohort study. SETTING: European rugby championships. PATIENTS OR OTHER PARTICIPANTS: Ninety-eight under-18 rugby players. MAIN OUTCOME MEASURE(S): All injuries sustained during the championship periods were recorded per the World Rugby protocol. RESULTS: A total of 40 injuries were logged over the 4 championships. The incidence of injury was higher during matches than during training (P < .05), with 138.0 (95% confidence interval [CI] = 136.5, 139.6) injuries per 1000 hours of play compared with 1.2 (95% CI = 1.2, 1.3) per 1000 hours of training. With only 2 days of rest between games, the injury rate was higher than with 3 days of rest (P < .05). More injuries were sustained during the third quarter of the game: 13 (44.8%) versus 6 (20.6%) in the last quarter, 5 (17.3%) in the second quarter, and 5 (17.3%) in the first quarter. CONCLUSIONS: The most common injuries during matches were sprains and concussions, and these injuries were more likely to occur during matches than during training. Most injuries were caused by tackles and occurred during the third quarter of the game. These findings indicate that teams should focus on teaching players skills to reduce injuries caused by tackles and warming up properly before returning to the field after halftime. The injury rate was higher with only 2 versus 3 days' rest between games. These results suggest that young players' matches should be at least 72 hours apart.

Combined Double Bundle Anterior Cruciate Ligament Reconstruction and Anterolateral Ligament Reconstruction.

A double-bundle anterior cruciate ligament (ACL) reconstruction associated with an anterolateral ligament (ALL) reconstructions is performed. The semitendinosus and gracilis are harvested. At knee maximum flexion, the anteromedial (AM) femoral tunnel is performed in the AM footprint area. Through the anterolateral portal, the tip of the outside-in femoral guide is placed in the posterolateral footprint area. The guide sleeve is pushed onto the lateral femoral cortex at the ALL attachment. At 110° knee flexion, the posterolateral-ALL tunnel is performed. The tibial ACL tunnel is performed as usual. The tibial guide is placed between the ALL tibial attachment and the tibial ACL tunnel entrance to perform the ALL tibial tunnel. The gracilis graft is introduced from caudal to cranial, achieving fixation with a 6-mm diameter screw (outside-in). The AM femoral fixation is achieved with a suspension device. ACL tibial graft fixation is achieved with a screw. Afterward, the gracilis is passed under the fascia lata to the tibial entry point. A 6-mm diameter screw is placed from the external cortex into the tibial ALL tunnel. The biomechanical advantage of the double-bundle ACL reconstruction with the biomechanical advantage of the ALL anatomic reconstruction is achieved.

Endoscopic Lesser Trochanter Resection With Refixation of the Iliopsoas Tendon for Treatment of Ischiofemoral Impingement.

Ischiofemoral impingement is a source of hip pain derived from impingement between the lesser trochanter and the ischium. Lesser trochanter excision has been recommended for recalcitrant ischiofemoral impingement through either an anterior or posterior approach. However, neither of these approaches involves refixation of the iliopsoas tendon. We describe an endoscopic procedure involving anterior trochanter-plasty, minimizing the risk of sciatic complications, with refixation of the partially detached iliopsoas tendinous insertion, potentially minimizing compromise to hip flexion strength and anterior hip stability.

Arthroscopic and Endoscopic Technique for Subcoracoid Synovial Chondromatosis of the Shoulder Through a Medial Transpectoral Portal.

Synovial chondromatosis of the shoulder is a rare disorder characterized by metaplastic synovial proliferation, causing multiple loose bodies usually localized intra-articularly. Surgical treatment with open techniques through a deltopectoral approach has been commonly used. The evolution of arthroscopy has allowed a complete joint assessment and the extraction of intra-articular loose bodies with less morbidity than open techniques. Nevertheless, this pathology occurs less frequently in the subcoracoid bursa. Access to this bursa may be more complicated when extracting loose bodies that cause pain and functional limitation in performing activities of daily living. We describe an arthroscopic and endoscopic technique for the treatment of subcoracoid synovial chondromatosis through a medial transpectoral portal, allowing safe loose body extraction under direct visualization around the coracoid process and brachial plexus. The literature was reviewed, and benefits of this endoscopic technique were analyzed.

Physical Exam and Evaluation of the Unstable Shoulder.

BACKGROUND: The clinical evaluation of the patient with shoulder instability can be challenging. The pathological spectrum ranges from the straightforward "recurrent anterior dislocation" patient to the overhead athlete with a painful shoulder but not clear instability episodes. Advances in shoulder arthroscopy and imaging have helped in understanding the anatomy and physiopathology of the symptoms. The aim of this general article is to summarize the main examination manoeuvres that could be included in an overall approach to a patient with a suspicion of instability. MATERIAL AND METHODS: In order to achieve the above-mentioned objective, a thorough review of the literature has been performed. Data regarding sensibility and specificity of each test have been included as well as a detailed description of the indications to perform them. Also, the most frequent and recent variations of these diagnostic tests are included. RESULTS: Laxity and instability should be considered separately. For anterior instability, a combination of apprehension, relocation and release tests provide great specificity. On the other hand, multidirectional or posterior instability can be difficult to diagnose especially when the main complain is pain. CONCLUSION: A detailed interview and clinical examination of the patient are mandatory in order to identify a shoulder instability problem. Range of motion of both shoulders, clicking of catching sensations as well as pain, should be considered together with dislocation and subluxation episodes. Specific instability and hyperlaxity tests should be also performed to obtain an accurate diagnosis.

Arthroscopic latarjet procedure.

Although soft tissue stabilization procedures in the shoulder yield good results, arthroscopy and radiological investigations have identified more complex soft tissue and bony lesions that can be successfully treated using a Latarjet procedure. The authors have advanced this technique to make it possible arthroscopically, thereby conferring all the benefits that arthroscopic surgery offers. This article describes how and why the arthroscopic Latarjet procedure is a valuable tool in the treatment of complex shoulder instability and how the procedure can be introduced into practice. This technique has shown excellent results at short- to mid-term follow-up, with minimal complications. As such, this procedure is recommended to surgeons with good anatomic knowledge, advanced arthroscopic skills, and familiarity with the instrumentation.
