Modified Posterior Approach to Total Hip Arthroplasty

This paper reviews the posterior approach to total hip arthroplasty and introduces the modified short external rotator muscle saving posterior approach, which enhances hip stability after total hip replacement arthroplasty. In total hip replacement arthroplasty, dislocation is the most common early complication. Especially in the posterior approach, dislocation is more common than in the anterior or lateral approach to the hip. However, preservation or meticulous repair of the short rotator could reduce the incidence of posterior hip dislocation after total hip replacement arthroplasty. With a brief review of the posterior approach to the hip, we introduce the short external rotater muscle saving modified posterior approach to total hip arthroplasty.

Posterior Approach to Total Hip Joint Replacement Arthroplasty

This paper was written to review the posterior approach for total hip arthroplasty and to introduce the modified short external rotator muscle saving posterior approach for enhancing the hip stability after total hip replacement arthroplasty. After total hip replacement arthroplasty, dislocation is the most commom early complication. Especially with using the posterior approach, dislocation is more common than that for the anterior or lateral approach to the hip. We report here that saving or meticulously repairing the short rotator could reduce the incidence of posterior hip dislocation after total hip replacement arthroplasty. Along with a brief review of the posterior approach to the hip, we introduce the short external rotator muscle saving modified posterior approach to total hip arthroplasty.

Avulsion Facture of Short External Rotators in the Proximal Femur: A Case Report

Although avulsion fractures of greater and lesser trochanters rarely develop in hip fractures, avulsion fracture of short external rotators has not reported still online literature. Moreover, avulsion fracture of short external rotators can simulate the intertrochanteric fracture, and is difficult to differentiate from it on plain radiograph. This study is on the case 74-year old male patient who had avulsion fracture of short external rotators, and had the internal fixation with wire by open reduction under the diagnosis of the intertrochanteric fracture.

Isokinetic Evaluation of Shoulder Joint Strength in College Handball Players and General College Students

OBJECTIVE: To obtain the comparison data of the shoulder strength between handball players of college and general college students. METHOD: Fifteen subjects from each group, college handball players and general college students groups were tested. Peak torque, peak torque ratio of internal rotator to external rotator, peak torque to body weight ratio and average work during isokinetic exercise were studied. RESULTS: All of the parameters tested in handball players of college were greater than those of general college students. The peak torque in handball players was greater than that of general college students at 60o/sec, 180o/sec, which was statistically significant (p<0.05). The peak torque ratio of internal rotator to external rotator in dominant side of handball players was greater than the college group (p<0.05). The peak torque to body weight ratio at 60o/sec did not show significant differences between handball players of college and general college students. The average power at 60o/sec did not show significant differences between the two groups. CONCLUSION: The values of peak torque ratio of internal rotator to external rotator of the shoulder joint in dominant side of handball players were greater than those of the general college students. So it was suggested this result have to be considered in selecting handball players and exercise prescription.
