The DSA is suggested as a minimally invasive surgical approach for THA, aiming to optimize outcome for THA patients. The DSA may provide an earlier functional recovery with slightly better functional scores in the first postoperative month.

2024年3月15日 · Background: Evolution of the surgical approach for total hip arthroplasty (THA) has led to the development of the minimally invasive direct superior approach (DSA). It is hypothesized that the DSA reduces postoperative pain and hospital length of stay (LOS).

Aims: The purpose of this study was to compare the clinical, radiological, and patient-reported outcome measures (PROMs) in the first 100 consecutive patients undergoing total hip arthroplasty (THA) via a direct superior approach (DSA) with a matched group of patients undergoing THA by the same surgeon, using a posterolateral approach (PLA).

2020年6月19日 · The direct superior approach (DSA) is a minimally invasive modification of the posterior approach (PA) that preserves the iliotibial band and short external rotators except for the piriformis or conjoint tendon during total hip arthroplasty (THA).

要旨：DSAは主に共同筋腱を切離し，外閉鎖筋腱や腸脛靱帯を温存する後方アプローチである。 そのメリットは温存筋腱によりTHAの安定性が得られやすく脱臼率が低いことや従来法である後方アプローチで起きうる下肢過延長になりづらい点，および術後の ...

2020年5月18日 · To assess the learning curve of the direct superior approach (DSA) for total hip arthroplasty (THA) and to compare surgical, clinical, and radiological results with a matched control group using the mini posterior approach (MPA).

The direct superior approach (DSA) is a relatively new development in recent years. The DSA is an improvement upon the PLA in THA, and utilizes an intermuscular and internervous plane between the tensor fasciae latae and the gluteus medius muscles, thus it provides direct visualization of the hip joint [7].

2023年4月24日 · 直接上入路 (DSA)是全髋关节置换术 (THA)的经典后外侧入路 (PLA)的改良，我们检查了DSA翻修的原因和风险，并与直接前路 (DAA)和PLA进行了比较。 复发性脱位是原发性全髋关节置换术 (THA)早期翻修的最常见原因。 复发性脱位的危险因素是手术入路和股骨头大小。 在荷兰，后外侧入路 (PLA)是髋关节置换术中最常用的入路 (50%)，尽管直接前路入路 (DAA)在过去几年中获得了相当大的普及。 与PLA相比，DAA与脱位翻修的风险降低有关，但先前有报 …

2023年10月10日 · Direct Superior Approach (DSA) is a new minimally invasive technique that has been applied in recent years. It is a muscle-sparing approach for hip joint replacement, similar to the posterior approach. It was first proposed by Stephen Murphy in 1999 and requires specific instruments to preserve the external rotator muscles' tendons.

2024年10月22日 · The DSA is particularly beneficial for younger patients or those undergoing outpatient THA, as well as very elderly patients with hip fractures, by reducing blood loss and transfusion rates and facilitating early ambulation and rehabilitation.
