Humeral Head Osteonecrosis: Outcomes of Hemiarthroplasty After Minimum 10-Year ...
Miyazaki,Alberto Naoki; Sella,Guilherme do Val; Silva,Luciana Andrade da; Checchia,Caio Santos; Lemos,Felipe CerávoloAbstract Objective To analyze long-term functional and radiographic results of partial shoulder replacement for humeral head osteonecrosis. Methods Retrospective review of thirteen cases, with a mean postoperative follow-up of 17 years (range 10 to 26 years). The findings from the last follow-up were compared to those in which the patients had one year of postoperative follow-up. Functional assessment consisted...
Current Options in Tendon Transfers for Irreparable Posterosuperior Rotator Cuf...
Checchia,Caio Santos; Silva,Luciana Andrade da; Sella,Guilherme do Val; Fregoneze,Marcelo; Miyazaki,Alberto NaokiAbstract Massive irreparable posterosuperior rotator-cuff tears are debilitating lesions that usually require surgical treatment. Even though there is no consensus regarding the best surgical technique, tendinous transfers around the shoulder are the most commonly performed procedures. The latissimus dorsi tendon remains the most commonly used, but different modifications to the original technique have been sho...
Comparative Clinical Evaluation of Two Techniques of Arthroscopic Treatment of ...
Sella,Guilherme do Val; Silva,Luciana Andrade da; Checchia,Caio Santos; Marmille,Hector Carmona; Santili,Cláudio; Miyazaki,Alberto NaokiAbstract Objectives To evaluate the clinical results of patients submitted to arthroscopic treatment of partial lesion of the articular part of the rotator cuff by transtendon suture techniques and after completing the lesion and to compare the postoperative recovery time of the two techniques. Method Retrospective study based on the identification of all cases with partial lesion of the articular part of the r...
Latissimus Dorsi Tendon Transfer using Tendinous Allograft for Irreparable Rota...
Miyazaki,Alberto Naoki; Checchia,Caio Santos; Lopes,Wagner de Castro; Fonseca Filho,João Manoel; Sella,Guilherme do Val; Silva,Luciana Andrade daAbstract Latissimus dorsi transfer around the shoulder is the most frequently used surgical technique to treat young patients with irreparable posterosuperior rotator cuff lesions. This technique, as initially described and popularized by Gerber et al., has two main drawbacks thatmay predispose to complications and unsatisfactory functional results: 1) postoperative rupture of the origin of the deltoid, as its ...
Articular reconstruction of the humeral head with autogenous allograft in the t...
Miyazaki,Alberto Naoki; Silva,Luciana Andrade; Sella,Guilherme do Val; Checchia,Caio Santos; Simionato,Marcos Cazer; Checchia,Sergio LuizABSTRACT The authors describe a surgical biological reconstruction of the humeral head with frozen autogenous allograft technique for the treatment of young patients with focal osteonecrosis of the humeral head. This represents a possible alternative, maybe even definitive for some patients, when compared to hemiarthroplasty or total shoulder arthroplasty. The technique consists of the fixation of a frozen auto...
Hill–Sachs lesion measurement with tridimensional models in anterior shoulder i...
Miyazaki,Alberto Naoki; Silva,Luciana Andrade; Santos,Pedro Doneux; Sella,Guilherme do Val; Nagaya,Leonardo Hideto; Checchia,Sergio LuizABSTRACT Objective To evaluate the reproducibility and repeatability of Hill–Sachs lesion measurement from computed tomography images, with computer software and tridimensional prototype. Methods Three-dimensional models were made from computed tomography images from 14 patients with anterior shoulder instability, using InVesalius 3.0® software. Hill–Sachs lesions were measured with Rhinocerus 5.0® software wit...
Clinical evaluation of arthroscopic treatment of shoulder adhesive capsulitis
Miyazaki,Alberto Naoki; Santos,Pedro Doneux; Silva,Luciana Andrade; Sella,Guilherme do Val; Carrenho,Leonardo; Checchia,Sergio LuizABSTRACT OBJECTIVE: To evaluate the results of arthroscopic releases performed in patients with adhesive capsulitis refractory to conservative treatment. METHODS: This was a retrospective study, conducted between 1996 and 2012, which included 56 shoulders (52 patients) that underwent surgery; 38 were female, and 28 had the dominant side affected. The mean age was 51 (29-73) years. The mean follow-up was 65 (12-...
Evaluation of the functional results after rotator cuff arthroscopic repair wit...
Miyazaki,Alberto Naoki; Santos,Pedro Doneux; Sella,Guilherme do Val; Checchia,Caio Santos; Salata,Thiago Roncoletta; Checchia,Sergio LuizABSTRACT OBJECTIVE: To evaluate the results of arthroscopic treatment of large and extensive rotator cuff injuries (RCI) that involved the supra and infraspinatus muscles using the suture bridge (SB) technique. METHODS: Between July 2010 and November 2014, 37 patients with RCI who were treated with SB technique were evaluated. The study included all patients with a minimum follow-up of 12 months who underwent p...
Infections after shoulder arthroplasty are correlated with higher anesthetic ri...
Nagaya,Leonardo Hideto; Salles,Mauro José Costa; Takikawa,Lucas Sadawo Chagas; Fregoneze,Marcelo; Doneux,Pedro; Silva,Luciana Andrade daABSTRACT Purposes: Shoulder arthroplasty (SA) has been performed by many years for the treatment of several conditions, including osteoarthritis and proximal humeral fractures following trauma. Surgical site infection (SSI) following Shoulder arthroplasty remains a challenge, contributing to increased morbidity and costs. Identification of risk factors may help implementing adequate strategies to prevent infect...
Are the good functional results from arthroscopic repair of massive rotator cuf...
Miyazaki,Alberto Naoki; Santos,Pedro Doneux; Silva,Luciana Andrade da; Sella,Guilherme do Val; Checchia,Sérgio Luiz; Yonamine,Alexandre MarisABSTRACT OBJECTIVE: To evaluate whether the good and excellent functional results from arthroscopic repair of massive rotator cuff tears are maintained over the long term. METHODS: From the sample of the study conducted by our group in 2006, in which we evaluated the functional results from arthroscopic repair of massive rotator cuff tears, 35 patients were reassessed, 8 years after the first evaluation. The in...
