arthroscopic anterior inferior Iliac Spine decompression does not alter postoperative muscle strength
Knee Surgery Sports Traumatology Arthroscopy, 2020Co-Authors: Satoshi Tateishi, Christopher M. Larson, Yasuo Onishi, Hitoshi Suzuki, Makoto Takahashi, Junichiro Shiraishi, Soshi UchidaAbstract:The purpose of this study was to assess the additional effect of anterior inferior Iliac Spine (AIIS) decompression on knee extensor and hip flexor strength and compare functional outcomes after arthroscopic FAI correction with and without AIIS decompression. Sixty patients who underwent arthroscopic FAI correction surgery were divided into two groups matched for AIIS morphology: 31 patients who underwent arthroscopic FAI surgery only (without AIIS decompression) (FAI group) (AIIS Type I; n = 5, Type II; n = 26, Type III; n = 0) and 29 patients who underwent arthroscopic FAI surgery with AIIS decompression (AIIS group) (AIIS Type I; n = 5, Type II; n = 24, Type III; n = 0). Knee extensor and hip flexor strength were evaluated preoperatively and at 6 months after surgery. Patient-reported outcome (PRO) scores using the modified Harris hip score (MHHS), the nonarthritic hip score (NAHS) and iHOT-12 were obtained preoperatively and at 6 months after surgery. In the AIIS group, there was no significant difference between knee extensor strength pre- and postoperatively (n.s.). In the AIIS group, hip flexor strength was significantly improved postoperatively compared to preoperative measures (p < 0.05). In the FAI group, there were no significant improvements regarding muscle strength (n.s.). While there were no significant differences of preoperative and postoperative MHHS and NAHS between both groups (MHHS; n.s., NAHS; n.s.), the mean postoperative iHOT-12 in the FAI group was inferior to that in the AIIS group. (p < 0.01). The revision surgery rate for the AIIS group was significantly lower compared with that in the FAI group (p < 0.05). Anterior inferior Iliac Spine decompression, as a part of an arthroscopic FAI corrective procedure, had a lower revision surgery rate and did not compromise knee extensor and hip flexor strength, and it improved clinical outcomes comparable to FAI correction without AIIS decompression. AIIS decompression for FAI correction improved postoperative PRO scores without altering the muscle strength of hip flexor and knee extensor. III.

anterior inferior Iliac Spine morphology correlates with hip range of motion a classification system and dynamic model
Clinical Orthopaedics and Related Research, 2013Co-Authors: Iftach Hetsroni, Christopher M. Larson, Lazaros A Poultsides, Asheesh Bedi, Bryan T. KellyAbstract:Background The anterior inferior Iliac Spine (AIIS) contributes to hip dysfunction in patients with symptomatic impingement and resection of a prominent AIIS can reportedly improve function. However, the variability of the AIIS morphology and whether that variability correlates with risk of associated symptomatic impingement are unclear.

making a case for anterior inferior Iliac Spine subSpine hip impingement three representative case reports and proposed concept
Arthroscopy, 2011Co-Authors: Christopher M. Larson, Bryan T. Kelly, Rebecca M StoneAbstract:Femoroacetabular impingement is typically described as occurring due to a conflict between the femoral head-neck junction and acetabular rim. A prior case report described an open decompression of the anterior inferior Iliac Spine (AIIS) due to impingement against the proximal femur. AIIS impingement may be developmental or the result of a prior AIIS avulsion or pelvic osteotomy. We describe 3 representative cases with minimum 1-year follow-up treated with an arthroscopic AIIS decompression.

Operative Fixation of an Anterior Inferior Iliac Spine Apophyseal Avulsion Fracture Nonunion in an Adolescent Soccer Player: A Case Report.
Journal of Bone and Joint Surgery American Volume, 2017Co-Authors: James B. Carr, Evan J. Conte, Evan Rajadhyaksha, Kevin A. Laroche, F. Winston Gwathmey, Eric W. CarsonAbstract:Case: A 14-year-old male competitive soccer player presented with a history of recurrent right hip pain for 18 months. He was diagnosed with an anterior inferior Iliac Spine (AIIS) apophyseal avulsion fracture nonunion with subspinal impingement, which was confirmed by radiographs, computed tomography, and magnetic resonance imaging. The patient underwent surgical fixation and subspinal decompression. He returned to competitive soccer 5 months postoperatively. Conclusion: AIIS apophyseal avulsion fractures occur in adolescent athletes and generally respond to nonoperative treatment. When such management is unsuccessful, surgical fixation can lead to resolution of pain with return of full function.

Outcomes for Arthroscopic Treatment of Anterior Inferior Iliac Spine (SubSpine) Hip Impingement.
Orthopaedic journal of sports medicine, 2017Co-Authors: Benedict U. Nwachukwu, Brenda Chang, Kara G. Fields, Jeremy Rinzler, Danyal H. Nawabi, Anil S. Ranawat, Bryan T. KellyAbstract:Background:Femoroacetabular hip impingement (FAI) is now well recognized; however, anterior inferior Iliac Spine (AIIS; or subSpine) impingement is a form of hip impingement that is underrecognized and can be an important source of hip disability and functional limitation.Purpose:To investigate the outcomes after arthroscopic treatment of AIIS/subSpine-related hip impingement in the absence of FAI surgery.Study Design:Case series; Level of evidence, 4.Methods:A prospective institutional hip preservation registry was reviewed to identify patients who underwent arthroscopic AIIS decompression without concurrent treatment of FAI. Primary outcome tools captured in the registry included the modified Harris Hip Score (mHHS), the Hip Outcome Score (HOS), and the International Hip Outcome Tool–33 (iHOT-33). Patients with minimum 1-year follow-up were included. Meaningful outcome improvement was determined per minimal clinically important difference (MCID). Statistical analyses were primarily descriptive.Results:T...

Anterior superior Iliac Spine avulsion in a young soccer player.
Annals of physical and rehabilitation medicine, 2010Co-Authors: I. Bendeddouche, B.b. Jean-luc, Serge Poiraudeau, A. NysAbstract:Avulsion fractures of the anterior superior Iliac Spine are rare. They usually occur in teenagers during sport activities. Cases concerning adults are very uncommon. We report here the case of a 23-year-old man who was admitted for recent pain of the left hip that worsened while kicking a ball in a soccer match eight days earlier. The examination found pain when moving the left hip in extension. Radiographs showed an avulsion fracture of the left anterior superior Iliac Spine, which was confirmed by computer tomography. The treatment was conservative consisting in rest and non-weight bearing with releasing of pain a few weeks later.

multiple osteochondroses and avulsion fracture of anterior superior Iliac Spine in a soccer player
British Journal of Sports Medicine, 2005Co-Authors: Mahmut Nedim Doral, Sedat Tolga Aydog, Onur Tetik, Ozgur Ahmet Atay, Egemen Turhan, Haydar A DemirelAbstract:Apophysitis describes a chronic traction injury at the insertion site of a tendon. There is a gradual onset of pain with no clear history of injury. Without adequate preventive methods, an avulsion fracture may result. The case is here reported of an apophyseal avulsion fracture of the anterior superior Iliac Spine in an adolescent caused by playing football before the end of treatment for apophysitis. An open reduction and internal fixation was performed followed by a rehabilitation programme. No complications occurred, and the patient had returned to his previous level of sporting activity after six weeks.
