Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games.

OBJECTIVES: Football is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. METHODS: Data were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. RESULTS: A total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. CONCLUSION: Shoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport. LEVEL OF EVIDENCE: III.

Acetabularization as a Protective Factor in Rotator Cuff Arthropathy.

Objective To check if shoulders with acetabularization have better functional results in cases of rotator cuff arthropathy. Methods A clinical and radiological cross-sectional evaluation of 65 shoulders with rotator cuff arthropathy by measuring the range of motion (RoM) of the shoulder, the Constant-Murley score, and the radiological classifications of Hamada and Seebauer. The clinical findings were compared with the radiographic findings. Results According to the classification of Seebauer, we observed better results regarding the RoM in type-A shoulders. There was a statistically significant difference regarding anterior elevation and medial rotation between types A and B ( p < 0.05). Lateral rotation did not show a statistically significant difference between types A and B. The Constant-Murley score presented better results in type A, and there was a statistically significant difference between groups A and B ( p < 0.05). According to the classification of Hamada, we observed that the RoM had better results in types 3, 2 and 1, and there was a statistically significant difference regarding anterior elevation and medial rotation ( p < 0.05) compared with groups 4A, 4B and 5. There was no statistically significant difference between the Hamada groups regarding lateral rotation. According to Hamada, the Constant-Murley score showed better results in types 3, 1 and 2, and there was a statistically significant difference between groups 3 and 5. Conclusion The RoM and shoulder function were better in patients with acetabularization (Seebauer 1A and Hamada 3), and worse in those with glenohumeral arthrosis (Seebauer 1B, 2B and Hamada 4A, 4B and 5).

Conclusão A ADM e a função do ombro apresentavam-se melhores nos pacientes com acetabularização (Seebauer 1A e Hamada 3), e piores naqueles com artrose glenoumeral (Seebauer 1B, 2B e Hamada 4A, 4B e 5).

Complex shoulder injuries in sports.

A 26-year-old Olympic wrestling athlete presented with a pectoralis major muscle injury, glenohumeral instability and acromioclavicular joint dislocation separately. The patient underwent surgical treatment to repair these injuries. The pectoralis major muscle was reconstructed with a semitendinosus tendon graft using the endobutton technique, as described by Pochini et al. Treatment of the traumatic anterior instability was performed using the technique described by Bristow-Latarjet, and the acromioclavicular joint dislocation was repaired using the modified technique of Weaver-Dunn with the aid of an anchor. The athlete exhibited a rapid recovery and could return to normal activities 6 months after surgery. At present, 18 months postoperatively, the patient is asymptomatic.

The pectoralis major footprint: An anatomical study.

OBJECTIVE: To study the insertion of the pectoralis major tendon to the humerus, through knowledge of its dimensions in the coronal and sagittal planes. METHODS: Twenty shoulders from 10 cadavers were dissected and the pectoralis major tendon insertion on the humerus was identified and isolated. The dimensions of its "footprint" (proximal to distal and medial to lateral borders) and the distance from the top edge of the pectoralis major tendon to apex of the humeral head structures were measured. RESULTS: The average proximal to distal border length was 80.8 mm (range: 70-90) and the medial-to-lateral border length was 6.1 mm (5-7). The average distance (and range) from the apex of the pectoralis major tendon to the humeral head was 59.3 mm. CONCLUSIONS: We demonstrate that the insertion of the pectoralis major tendon is laminar, and the pectoralis major tendon has an average footprint height and width of 80.8 mm and 6.1 mm, respectively.

OBJETIVO: Estudar a inserção do tendão do peitoral maior no úmero, por meio do conhecimento de suas dimensões nos planos coronal e sagital. MÉTODOS: Foram dissecados 20 ombros de dez cadáveres frescos (cinco homens e cinco mulheres). Todos os cadáveres encontravam-se em bom estado, sem cicatrizes ou sinais de trauma prévios. Fez-se o estudo por meio da via deltopeitoral estendida e foi identificada e isolada a inserção do tendão do peitoral maior no úmero. Mensuraram-se as dimensões do footprint por meio das aferições com um paquímetro milimetrado, de seus limites de proximal para distal e medial para lateral. Foi aferida a distância da borda superior do tendão do peitoral maior ao ápice da cabeça umeral. RESULTADOS: Em todos os cadáveres o peitoral maior apresentou uma inserção única. O comprimento médio de proximal para distal foi de 80,8 mm (70-90) e de lateral para medial de 6,1 mm (5-7). Já a distância média do ápice do tendão do peitoral maior ao ápice da cabeça umeral foi de 59,3 mm (55-64). CONCLUSÕES: O tendão do músculo peitoral maior apresenta inserção laminar. O footprint tem a altura e a largura média de 80,8 mm e 6,1 mm, respectivamente.

Anatomic study of the coracoid process: safety margin and practical implications.

PURPOSE: The aim of this study was to define a safety margin for coracoid process osteotomy that does not compromise the coracoclavicular ligaments and that can be used in the coracoid transfer procedures. METHODS: Thirty shoulders from 15 cadavers were dissected, exposing the coracoid process and attached anatomic structures. The distance of the insertion of these structures to the coracoid process apex was measured. RESULTS: The average length of the coracoid process was 4.26 ± 0.26 cm. The average width and height at the tip were 2.11 ± 0.2 and 1.49 ± 0.12 cm, respectively. The average distance from the tip to the anterior and posterior margin of the pectoralis minor was 0.1 ± 1.17 and 1.59 ± 0.27 cm, respectively. The average distance from the tip to the posterior margin of the coracoacromial ligament was 2.79 ± 0.33 cm. The average distance from the apex to the most anterior part of the trapezoid ligament was 3.33 ± 0.38 cm. We obtained a constant value of 0.85 cm for this measure, and the value increased with each 1.0-cm increase in the distance from the tip to the posterior margin of the pectoralis minor. The safety margin for osteotomy (i.e., available bone distance for the coracoid process transfer) was 2.64 cm. CONCLUSIONS: This study established a safety margin of 2.64 cm for the osteotomy of the coracoid process and its relation with the posterior margin of the pectoralis minor. The anatomic descriptions of bone and soft tissue, as well as a measure of correlation for the safety margin of the coracoid, provide tools for surgeons performing anatomic surgical procedures to correct glenohumeral instability with significant bone loss. CLINICAL RELEVANCE: Knowing the safety margin allows the surgeon to perform a safe osteotomy without direct visualization of the coracoclavicular ligaments attachments, thereby making procedures more anatomic.

OSTEOTOMIES OF THE CORACOID PROCESS: AN ANATOMICAL STUDY.

OBJECTIVE: Relate the main tendinous and ligamentous structures attached in the coracoid process, correlating it to several levels of osteotomy and describing the involved structures. METHODS: Thirty shoulders were dissected. The coracoid process with mainly inserted anatomic structures was dissected, and five levels of osteotomy (1.0; 1.5; 2.0; 2.5; 3.0 cm) were made from the apex of the process and the mainly involved structures were recorded. RESULTS: In osteotomies of 1.0 cm, in 100% of the cases only the conjoint tendon (CT). In osteotomies of 1.5 cm there were 63.33% of cases involved with the CT and the Pectoralis minor (PMi), in 20% of cases only the CT, and in 16.66% the CT, PMi, and the coracohumeral ligament (CUL). In osteotomies of 2.0 cm, in 80% of the shoulders, the osteotomies embraced the CT, PMi and the CUL, and in 20% only the CT and the PMi were involved. In the osteotomies of 2.5cm there was involvement of the CT, PMi and CUL in 100% of cases. In the osteotomies of 3.0cm, six cases (20%) have presented an injury on the trapezoid ligament, and in 100% of these osteotomies, the osteotomized distal fragment had embraced the CT, PMi, CUL. CONCLUSION: The knowledge of anatomic structures inserted and involved in the osteotomies cuts of the coracoid process is very importan to lead with osteotomies performed in the treatment techniques of the coracoid process. Osteotomies of 3.0 cm can injure the trapezoid ligament.

Exact moment of bilateral scapular fracture during skydiving captured on video.

A skydiving athlete suffered bilateral scapular fracture while jumping from the plane. A camera showed the exact moment of fracture. The injury seemed to occur during hyperextension of the arms; however, the most common mechanism of fracture is during direct trauma of the shoulder. The patient was treated by immobilisation with a sling for 3 weeks and had a good outcome. Clinical and radiographic consolidation occurred 8 weeks after the injury. The athlete returned to competitive activities after 4 months.

An iliac bone stress fracture in a basketball player.

The authors describe the case of an athlete from the Brazilian national men's basketball team (sub-16) who reported pain in the right iliac region at the end of the season. Clinical and imaging exams revealed an iliac bone stress fracture. A conservative treatment of removing the load from the fracture in combination with physical therapy was chosen. The athlete improved satisfactorily and returned to the sport at the same level as prior to the injury after 14 weeks of treatment.
