We retrospectively analyzed 22 patients pelvic CT, in whom the acetabular fracture were suspected in plain film. And compared and analyzed the computed tomogram findings and plain radiographic findings. The results were as follows. CT enables better evaluation of shape, extent, and degree of separation of fragment. CT was helpful in detecting the combined fracture and soft tissue injuries. CT showed intraarticular loose bodies, which were invisible on plain film. In patients with pelvic trauma, no necessary changing position during CT examination. CT was useful demonstrates the remnant of intraarticular osseous fragment and adequacy of reduction after surgery.

Percutaneous pelvic fixation is possible with the advances in intraoperative fluoroscopic imaging and other technologies. Percutaneously inserted screws in medullary pubic ramus,iliac wing, and iliosacral bone can stabilize pelvic or acetabular disruptions directly mean while can diminish operative blood loss, shorten operative time, and allow patient's early activity. Complications associated with open surgical procedures are similarly avoided by using percutaneous techniques. Stable and safe percutaneous fixation techniques depend on accurate closed reduction, excellent intraoperative fluoroscopic imaging, and detailed preoperative planning. A thorough knowledge of pelvic osseous anatomy, injury patterns, deformities, and the related intraoperative imagery techniques are essential for doctors to fulfill the operation of percutaneous pelvic fixation. This paper presents an overview of the technique of percutaneous surgery of the pelvis and acetabulum.

PURPOSE: To evaluate the results of limited open reduction and screw fixation of acetabular fractures. MATERIALS AND METHODS: Six acetabular fractures were treated with fluoroscopic guided screw fixation. The mean age was 46 years old and mean follow-up period was 18 months. There were 3 anterior column fractures, 2 transverse fractures and 1 both column fracture. Anterior column screw fixation was used in 5 cases and posterior column fixation in 1 case. Limited ilioinguinal approach was used in 4 cases and percutaneous screw fixation in 2 cases. RESULTS: The mean union time was 16.6 weeks. The postoperative radiographic results revealed 2 cases with an anatomic reduction and 4 cases with an imperfect reduction. The clinical results showed 1 case with excellent, 4 cases with good and 1 case with fair. Regarding complication, there was 1 case of SI joint penestration without clinical symptoms. CONCLUSION: Limited open reduction and screw fixation can be a useful alternative treatment for acetabular fractures in patients with minimally displaced fracture, severe multisystem trauma and soft tissue injury not suitable to traditional treatment.

In a retrospective study of 21 patients, in whom the acetabular fractures were suspected on initialradiographs, we compared and analysed the CT findings and plain radiographic findings and plain radiographicfindings. The results were as follow: 1. In patients with multiple trauma, no further change in position wasrequeired during CT examinations. 2. CT showed intraarticular loose bodies, which were invisible on plainradiographs. 3. CT was useful in detecting the fractures of acetabular rims, medial wall of acetabulum, andfemoral head. 4. CT permitted better evaluation of shape, extent, and degree of separation of fracture fragments.5. CT was helpful indetecting the associated fractures and soft tissue injuries. 6. CT also demonstrated theadequacy of reduction, the position of metallic fixation devices, and the presence or absence of remainingintraarticular osseous fragments after surgery.

OBJECTIVETo explore morphological character and clinical significance of superior-posterior acetabular wall by anatomically measuring and quantitatively analyzing thickness of posterior acetabular wall, then provide a theoretical reference for clinical treatment of acetabular fracture.

METHODSFifteen adult formalin-preserved cadaveric pelvises (8 males and 7 females) were used for this investigation. Excess soft tissue was removed and the whole acetabular posterior walls were marked with "angle" sector method and the thickness was measured with caliper in different levels of the different split points. The measurement results were validated and analyzed statistically.

RESULTSAt 5 mm away from acetabular rim, the average thickness of superior-posterior acetablar wall fluctuated between (6.47±0.61) mm and (7.43±0.71) mm; the average thickness of inferior-posterior acetabuluar wall fluctuated between (5.62±0.51) mm and (6.33±0.61) mm; the average thickness of acetabular roof fluctuated between (7.71±0.74) mm and (8.27±0.99) mm. There was no statistical difference between average thickness of superior-posterior wall of acetabulum and inferior-posterior wall of acetabulum (P>0.05), but the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P<0.05). At 10 mm away from the acetabular rim, the average thickness of superior-posterior acetabular wall fluctuated between (8.81±0.67) mm and (13.35±0.89)mm; the average thickness of inferior-posterior acetabular wall fluctuated between (7.02±0.63) mm and (7.66±0.69) mm; the average thickness of acetabular roof fluctuated between (14.46±0.97) mm and (17.05±1.35) mm. Comparatively, the average thickness of superior-posterior acetabular wall was significantly larger than inferior-posterior wall of acetabulum (P<0.05), and the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P<0.01). At 15 mm away from the acetabular rim, the average thickness of superior-posterior acetabular wall fluctuated between (12.08±0.78) mm and (19.84±1.03) mm; the average thickness of inferior-posterior acetabular wall fluctuated between (10.17±0.76) mm and (11.12± 0.77) mm; the average thickness of acetabular roof fluctuated between (23.23±1.12) mm and (26.01±1.53) mm. Comparatively, the average thickness of superior-posterior wall of acetabulum was significantly larger than inferior-posterior acetabular wall (P<0.01), and the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P< 0.01).

CONCLUSIONThe thickness of entire acetabular posterior edge revealed an increasing tendency from inferior-posterior wall to the superior-posterior wall to acetabular roof. And this trend became more obvious with increasing distance away from acetabular rim. Therefore, the superior-posterior acetabular wall could not only maintain the stability of hip joint but also bear loading.

OBJECTIVE: To review the literature regarding diagnosis and treatment of labral tear. DATA SOURCES: A systematic search was performed in PubMed using various search terms and their combinations including hip, labrum, acetabular labral tear, arthroscopy, diagnosis, and anatomy. STUDY SELECTION: For each included study, information regarding anatomy, function, etiology, diagnosis, and management of acetabular labral tear was extracted. RESULTS: Five hundred and sixty abstracts about anatomy, function, etiology, diagnosis, and management of acetabular labral tear were reviewed and 66 selected for full-text review. The mechanism of labral tear has been well explained while the long-term outcomes of various treatment remains unknown. CONCLUSIONS Labral tear is generally secondary to femoroacetabular impingement, trauma, dysplasia, capsular laxity, and degeneration. Patients with labral tear complain about anterior hip or groin pain most commonly with a most consistent physical examination called positive anterior hip impingement test. Magnetic resonance arthrography is a reliable radiographic examination with arthroscopy being the gold standard. Conservative treatment consists of rest, non-steroidal anti-inflammatory medication, pain medications, modification of activities, physical therapy, and intra-articular injection. When fail to respond to conservative treatment, surgical treatment including labral debridement, labral repair, and labral reconstruction is often indicated.

OBJECTIVETo study the clinical significance of computed tomography (CT) in diagnosis and treatment of acetabular fractures.

METHODSThe plain and CT films of the 66 cases of acetabular fracture from January 2001 to June 2002 were analyzed retrospectively, and the radiological characteristics and results were compared to each other.

RESULTSThe diagnosis of 6 cases were changed after CT examination, and the occurrence ratio of marginal impaction, free body in joint, femoral head fracture, sacro-iliac injury and ischial tubersoity fracture involvement were 3:17, 7:29, 6:15, 0:5 and 1:5 in plain and CT examination respectively.

CONCLUSIONSCT examination has the determinative role in detecting weight-bearing zone, marginal impaction, free body, femoral head fracture, sacro-iliac injury, etc., and for completing the diagnosis and guiding the treatment. It should be the routine examination just as the three standard plain examinations in acetabular fractures, and should be carefully read.

Various musculoskeletal injuries are well known complications of epilepsy either because of direct trauma or because of unbalanced forceful muscle contraction. We report a case of non-traumatic bilateral central acetabular fracture dislocation due to seizure activity induced by neurocysticercosis of the brain, which was managed conservatively and obtained reasonable good outcome. This case highlights the importance of proper evaluation in young non-osteoporotic patients who have experienced an epileptic attack without any previous history. It is also imperative to mention that these patients should be thoroughly examined neurologically to find out the exact etiology and should be treated accordingly to prevent future seizure activity.
