“…A large bony spur was frequently seen in the painful Bennett group, suggesting the possibility of internal impingement (posterior impingement), 5,8,10 consistent with the report by Meister et al 7 that large bony spurs can cause internal impingement. However, the incidence of damage to the posterior labrum and rotator cuff, which are thought to impinge on each other internally, was similar between the painful Bennett group and the asymptomatic Bennett group.…”

“…[1][2][3]6,7 In addition, local irritation of the joint capsule and axillary nerve by the bony spur and internal impingement have been suggested as possible causes for how the bony spur induces posterior shoulder pain in throwing. [6][7][8] The pathologic significance of the Bennett lesion is still controversial, and which type of Bennett lesion induces throwing pain is not clear. The purposes of this study were to identify the clinical characteristics associated with a painful Bennett lesion and to try to predict which type of Bennett lesion would become symptomatic by the clinical findings.…”

“…These were distinct from typical Bennett lesions as described by several authors [3,12,16] and we presumed they would cause painful abutment on the spur (Fig. 2).…”

“…We also noticed a posterior spur was common in throwing athletes. There had been reports of open resection of posterior ossifications in throwing athletes with unreproducible results [2,12,13,16]; however, Ozaki et al [16] reported an improvement in all parameters in a series of seven baseball pitchers and Meister et al [13] suggested 10 of 18 players returned to their previous level of throwing. In 1996, we thus decided to generalize the glenoidplasty in arthroscopic treatment of PGSI [10].…”

Background Posterosuperior glenoid impingement (PSGI) is the repetitive impaction of the supraspinatus tendon insertion on the posterosuperior glenoid rim in abduction and external rotation. While we presume the pain is mainly caused by mechanical impingement, this explanation is controversial. If nonoperative treatment fails, arthroscopic débridement of tendinous and labral lesions has been proposed but reportedly does not allow a high rate of return to sports. In 1996, we proposed adding abrasion of the bony posterior rim, or glenoidplasty.

Background: A variety of thrower’s exostoses are grouped under the term Bennett lesion, which makes understanding diagnosis and treatment difficult. Purpose: To identify all types of reported thrower’s and overhead athlete’s exostoses and categorize them into a classification system to allow a morphology-based classification. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of all articles pertaining to Bennett lesions and thrower’s exostosis was performed. The classification and treatments were evaluated to describe the types, proposed causes, diagnosis, and treatment options. Results: A total of 27 studies were included in the systematic review. The anatomic locations referenced in the study demonstrated posteroinferior, posterior, and posterosuperior glenoid lesions. Aggregate radiographic data demonstrated 158 of 306 patients (52%) with a thrower’s exostosis of any type and location. Of these 158 patients with a radiographic lesion, 119 (75%) patients were symptomatic. The locations were posteroinferior in 110 patients (70%), directly posterior in 2 patients (1.3%), posterosuperior in 44 patients (28%), and unknown in 2 patients (1.3%). Avulsed lesions were present in 9 (5.7%) posteroinferior lesions, 0 direct posterior lesions, and 2 (1.3%) posterosuperior lesions. Treatment plans included both nonoperative and operative strategies, but operative intervention was more commonly reported for detached lesions. After operative intervention, only 61% of reported athletes returned to preinjury performance. Conclusion: Based on a comprehensive review of the literature, we identified several anatomic locations for a thrower’s exostosis beyond the classic Bennett lesion. We categorized the reported exostoses into a new classification system for description of location and type (subperiosteal or free fragment) of the thrower’s exostosis, which may be used to study future treatments. Current treatment strategies recommend that surgical treatment of thrower’s exostosis is considered only after exhausting nonoperative management because reported return to sport is variable after surgery. The effectiveness of excision or repair for both subperiosteal and detached lesions has not been established.
