Estudo comparativo entre a haste intramedular bloqueada e a placa em ponte no tratamento cirúrgico das fraturas da diáfise do úmero / Comparative study using nonreamed intramedullary locking nail and bridging plate for the treatment of humeral shaft fracturesEduardo Benegas 10 December 2008 (has links)
O objetivo deste estudo é o de comparar os resultados clínicos e radiográficos do tratamento cirúrgico das fraturas da diáfise do úmero com haste intramedular bloqueada ou placa em ponte. Quarenta fraturas da diáfise do úmero, em 39 pacientes, dos tipos A, B ou C da classificação do grupo A.O., foram tratadas no período compreendido entre junho de 2003 e dezembro de 2007. Destas, após seleção por sorteio, 21 fraturas foram submetidas à osteossíntese com placas em ponte de 4,5 mm e parafusos (grupo PP) e 19 com hastes intramedulares bloqueadas não fresadas (grupo HIB). Duas eram fraturas expostas, uma do tipo II e outra do tipo III-a de Gustilo. Vinte e cinco pacientes eram do sexo masculino (64%) e a idade variou de 19 a 75 anos (idade média de 41 anos e 10 meses). O lado direito foi acometido em 22 pacientes (55%) e a queda, o mecanismo de trauma mais freqüente (46%). O tempo mínimo de seguimento foi de seis meses e o máximo de 60 meses para o grupo PP (M=34,5 meses) e de oito e 58 meses (M=27meses) para o grupo HIB. Em apenas um caso, operado com haste intramedular bloqueada, não houve a consolidação. Houve um caso de infecção profunda no grupo PP e um de infecção superficial no grupo HIB. Dois casos do grupo PP evoluíram com capsulite adesiva e, em apenas um dos casos do grupo HIB, o parafuso distal ficou saliente. Ocorreu neuropraxia do nervo cutâneo lateral do antebraço em um dos casos do grupo HIB que regrediu em três dias. Não houve diferença entre os grupos com relação ao tempo total da cirurgia. O tempo de utilização da radioscopia no ato operatório foi maior no grupo HIB. Houve semelhança entre os dois métodos de fixação nos resultados referentes à dor, à função, à flexão ativa e à força de flexão na articulação do ombro e também com relação à dor, mobilidade, força muscular e estabilidade na articulação do cotovelo. Segundo os critérios da UCLA para o ombro, obtivemos resultados excelentes e bons em 85,7% no grupo operado com placa em ponte e 79% no grupo com haste intramedular bloqueada e de acordo com os critérios de Broberg e Morrey para o cotovelo, obtivemos resultados excelentes e bons em 85,7% no grupo operado com placa em ponte e 90,5% no grupo com haste intramedular bloqueada. Na avaliação subjetiva, duas pacientes, uma do grupo HIB e outra do PP, não ficaram satisfeitas. Conclusão: Não houve diferença no resultado clínico e radiográfico entre os dois métodos / The purpose of the study is to compare clinical and radiographic outcomes between nonreamed locked intramedullary nail and bridging plate for the treatment of humeral shaft fracture. Forty humeral shaft fractures in 39 patients, A, B or C AO types were treated between June 2003 and December 2007. The cases were randomly assigned into two groups being 21 fractures fixed by a 4.5 mm bridging plate, and 19 by nonreamed intramedullary locking nail. Two cases had open fractures, one Gustilo type II, the other type IIIa. Twenty five patients were male (64%), ages ranging from 19 to 75 years old (mean age 41 years and 10 months). The right side was treated in 22 patients (55%) and fall was the most frequent cause of fracture (46%). The minimal period of follow-up was six months and the maximum was 60 months for the bridging plate group (mean=34.5 months) and ranged from eight to 58 months (mean=27months) for the nail group. Only one case from the nail group presented a nonunion. One case, in the plate group, developed a deep infection, and another one, in the nail group, had a superficial infection. Two cases of the bridging plate group had adhesive capsulites and in one case of the nail group the distal screw became prominent. A transient neuropraxis of the antebrachial lateral cutaneous nerve was found in one case of the nail group, but it recovered in three days. There were no differences between the groups concerning pain, function, active flexion and strength of flexion of the shoulder, as well as pain, range of motion, muscle strength, and stability of the elbow. According to the UCLA score, we had 85.7% excellent and good results in the plate group and 79% in the nail group. According to Broberg and Morrey score for the elbow, we had 85.7% excellent and good results in the plate group and 90.5% in the nail group. Just one patient, from the nail group, was not satisfied with the final result, according to subjective criteria. In conclusion, there were no differences in the final clinical and radiographic results between the two methods of fixation

Complex Functional Posttraumatic Shoulder Reconstruction Using Shoulder Arthroplasty and a Pedicled Innervated Latissimus Dorsi Flap: A Case Report and Literature ReviewBota, Olimpiu, Dragu, Adrian, Bönke, Florian, Tille, Eric, Taqatqeh, Feras, Nowotny, Jörg 22 February 2024 (has links)
Background: The shoulder joint is one of the most freely movable joints in the human body and has therefore high importance for upper limb functionality. Several techniques have been developed to replace the glenohumeral joint including humeral hemiarthroplasty, anatomical total shoulder arthroplasty, and reverse total shoulder arthroplasty, depending on the underlying pathology. For the soft tissue reconstruction, the innervated latissimus dorsi musculocutaneous flap is a reliable solution flap in shoulder and arm reconstruction. - Case presentation: We present the case of a 16-year-old male patient with a complete destruction of the shoulder joint and soft tissues after ballistic trauma. We performed the reconstruction of the shoulder joint using a humeral hemiarthroplasty with a mesh fixation to the remaining glenoid. The soft tissue coverage and the restoration of the deltoid muscle function were insured with a pedicled innervated latissimus dorsi musculocutaneous flap. One year postoperatively, the patient showed a good function of the shoulder joint with an excellent aesthetical result and no pain. - Conclusion: The pedicled latissimus dorsi musculocutaneous flap can safely restore the shoulder function, while the humeral hemiarthroplasty with mesh fixation can be a reliable solution for the reconstruction of a completely destructed shoulder joint.
