For hemiarthroplasty reconstruction of a proximal humeral fracture, accurate restoration of humeral head position is challenging, and incorrect prosthetic placement is associated with a poor outcome of surgical treatment. The purpose of this study was to validate the pectoralis major tendon as a reproducible landmark for accurate restoration of humeral(More)
To determine if it is possible to measure glenoid bone loss by using the Bernageau view and to compare it to a 3D CT scan. Fifty healthy subjects with a mean age of 34 ± 8 years old and 31 (62 %) male were submitted to the Bernageau view X-ray of both shoulders. Three blinded evaluators measured the distance between the posterior and anterior glenoid rim.(More)
BACKGROUND The coracoid has been widely used as a graft to reconstruct anterior glenoid bone defects, as described by the Latarjet and Bristow procedures, with successful results. Nevertheless, at the present, there are no studies correlating the size of the coracoid graft and its relation to the glenoid. PURPOSE To assess the mediolateral (M-L) and(More)
OBJECTIVE To evaluate the presence of x ray changes in the proximal humerus growth plate of 21 young pitchers. DESIGN Case series. SETTING This study was conducted at the Orthopaedic and Traumatology Department of the ABC College of Medicine, Santo André, São Paulo, Brazil, tertiary institution. PATIENTS 21 male adolescent baseball pitchers, with a(More)
OBJECTIVE To compare the functional results among patients undergoing tenotomy with or without tenodesis of the long head of the biceps associated with arthroscopic repair of rotator cuff injuries, with a minimum two-year follow-up. METHOD This was a retrospective non-randomized trial with evidence level III, in which the medical files of 77 patients with(More)
OBJECTIVE To analyze whether the Bernageau radiographic view is adequate for studying the anterior glenoid rim and to determine the distance between the posterior and anterior glenoid rims. METHODS Fifty patients (31 males) with a mean age of 34 years were evaluated by positioning their arm at 160° forward flexion and body at 70° to the x-ray chassis,(More)
OBJECTIVE To determine: 1) whether the patients had been oriented to use immobilization for at least four weeks and which type of immobilization was prescribed, 2) how many dislocations occurred until the patient received information about the need of surgery, 3) How long it takes for patients to have an appointment with a shoulder surgeon, 4) How many(More)
OBJECTIVE To determine the distance between the axillary nerve and the antero-lateral (AL) edge of the acromion, its anatomical variability and relationship to humeral length and body height. METHODS Twenty-two shoulders were dissected. The anterosuperior (AS) approach was used; the deltoid was detached from the acromion and the distance between the AL(More)
OBJECTIVE To evaluate bone healing and the patient's outcome after open reduction and internal fixation, when using the technique described by Walch et al, in 1996, which uses conventional intramedullary corticocancellous bone graft and internal fixation with plate and screws added by a tricortical intramedullary bone graft, also autologous. METHODS From(More)
BACKGROUND We aimed to establish values and parameters using multislice reconstruction in axial computerized tomography (CT) in order to quantify the erosion of the glenoid cavity in cases of shoulder instability. METHODS We studied two groups using CT. Group I had normal subjects and Group II had patients with shoulder instability. We measured values of(More)
