PURPOSE: To evaluate the correlation between MRI findings and hip joint lesions evaluated by arthroscopy in patients affected by paralabral cyst. MATERIALS AND METHODS: Of patients treated by hip arthroscopy from Jan 1996 to Mar 2010, 17 cases symptomatic of paralabral cyst as observed by preoperative MRI were analyzed. The presence of an acetabular labrum tear, and the location and size of the cyst were evaluated using both preoperative MRI and intraoperative arthroscopy. Visual analogue scale (VAS), modified Harris hip scale, and Hip outcome score results were compared as determined by the two assessment methods. RESULTS: According to the MRI findings, the locations of the cysts included 5 cases in the anterosuperior, 2 anterior, 4 anteroinferior, 2 posterosuperior and 4 posteroinferior. The mean size of all cysts was 25.1x12.5x13.8 mm3. Postoperatively, the mean VAS score for all patients improved from 7.7 to 1.5, their modified Harris hip score improved from 58.8 to 90.7, and their Hip outcome score improved from 54 to 93.5. CONCLUSION: Painful paralabral cyst was mainly associated with an acetabular labral tear and we concluded that observation of paralabral cyst upon preoperative MRI provided indirect evidence of proximal acetabular labral pathology.

Congenital fibrous bands may be found at the gluteus maximus, the gluteus medius,thequadriceqs,the triceps and the deltoideus muscles. Congenital fibrous bands of both gluteus maximus muscles are rare and cause extension contracture of the hip joints. We experienced a case of congenital fibrous bands of both gluteus maximus muscles associated with severe limited flexion of both hips. Almost full flexion of both hips was obtained by excision of the congenital fibrous bands.

We experienced two cases of asymptomatic intrapelvic masses with calcific density walls in failed cementless total hip arthroplasties. The intrapelvic masses communicated with the hip joint along the screw in one case and a medial wall defect in the other case. Instead of excision, the masses were drained and the failed components were revised. Two years after revision arthroplasties, the intrapelvic masses have not increased in size; and there was a thick calcific density wall in the second case. We conclude that the excision of an intrapelvic mass is not always mandatory when it is symptomless.

Fracture of the femoral head is relatively uncommon and usually caused by high energy injury. The femoral head fracture combined with hip dislocation results in severe damage to the hip joint, and therefore has been associated with poor functional outcome. The principle of the treatment is composed of urgent reduction of the dislocated hip and early anatomical reduction, with the goal of restoring a congruent and stable hip. In an effort to reach that goal, several methods have been used for treatment of the fracture after closed reduction of the hip. The purpose of this article is to review the indication of surgery, surgical methods, surgical approach, and clinical outcomes.

Background: Different trochanteric osteotomies have been developed to aid in surgical exposure and proper removal and placement of arthroplasty components. Objectives. The study aimed to measure functional outcomes of the modified trochanteric slide approach for both primary and revision hip arthroplasty with radiologic and clinical variables, identify preoperative indications for the approach and identify possible postoperative complications. Methods: We conducted a retrospective case series of patients who underwent the modified trochanteric slide approach for hip arthroplasty at the orthopedic department of a tertiary hospital from 2012 to 2016. We reviewed patient charts and radiographs. Descriptive statistics were used to analyze data. Results: Out of nine patients screened, seven were included. The average post-op hip range of motion was 42 degrees abduction and 98 degrees flexion. The union rate was 36% and the non-union rate was 7%. Conclusion The modified osteotomy is still recommended for difficult primaries and revisions to aid in exposure and hip biomechanics post-operatively.
