Bilateral shoulder dislocations are rare and almost always occur in the posterior direction. Simultaneous bilateral anterior shoulder dislocation is even rarer and only a few cases are stated in the literature. The most interesting part of a bilateral shoulder dislocation is about its injury mechanism as a synchronous and simultaneous force is needed to result in it. In cases of epilepsy or electrocution, the mechanism is different and the forceful contractions of the selective group of muscles result in the dislocation. This article reports two cases of bilateral simultaneous anterior shoulder joint dislocation that occurred after a road side accident and after an episode of convulsion in an epileptic patient. The dislocations were diagnosed early and reduced immediately with a proper postreduction rehabilitation. During their follow-up, both patients had sa-tisfactory functional outcome. This article emphasizes on the importance of shoulder examination in road side accident victims and epileptic patients. All orthopedic surgeons and emergency physicians should be aware of such unusual possibilities to have an early diagnosis and treatment. An early reduction and appropriate rehabilitation can provide satisfactory functional outcome. This article also briefly discusses the injury mechanisms, diagnoses and treatments of bilateral shoulder dislocation as reported in the literature.

While clavicular injuries are fairly common, bipolar clavicular injuries are not. They may involve dislocations at both ends of the clavicle, or a fracture at one end and a dislocation at the other. We present two cases; a patient with a bipolar clavicular dislocation, and another with a fracture in both medial and lateral ends of the clavicle with anterior dislocation of the sternoclavicular joint. Both were treated conservatively, with fairly good range of motion and return to normal activity.

To assess the curative effects of different reduction techniques on the dislocation of cricoarytenoid joint caused by intubation, indirect laryngoscope (IL) and direct laryngoscope (DL) were utilized for the closed reduction of the displaced arytenoid under local anesthesia. 23 patients who underwent the reduction for dislocated arytenoid under IL or DL from January 1991 to June 2001 were reviewed. The data were collected on the duration of the laryngeal injury, times of receiving reduction, side-effects after the treatment and the period for voice to return to normal. The relationship between the duration of the laryngeal lesion and the period of the voice rehabilitation was examined. 13 patients received the reduction under IL and 10 patients under DL. Except the times of the reduction, which showed significant difference, no differences were found between IL group and DL group in the course and the period of voice rehabilitation, as well as sore throat after the manipulation. The patients' voice recovery was positively related to their course of disease in both IL and DL group. It is concluded that the recovery of normal voice is obviously affected by the duration of arytenoid dislocation. The reduction under IL is as effective as under DL in the treatment of arytenoid dislocation. Reduction by DL is better suit the patients with long time course of disease.

OBJECTIVE: To explore and compare the safety depths of perpendicular and oblique acupuncture at Yamen (GV 15) in patients with atlantoaxial dislocation (AAD) and healthy volunteers. METHODS: One bundred and seventy-seven patients with atlantoaxial dislocation were selected as an AAD group, and 207 patients without atlantoaxial dislocation and with normal anatomical structure were selected as a normal group. All participants were moderately sized. The MRI scanning of the cervical vertebra was performed, and the safety depth of perpendicular and oblique acupuncture at Yamen (GV 15) was calculated on the sagittal image. RESULTS: In the AAD group, the safety depth of men was (45.33±5.17) mm for perpendicular acupuncture and (48.58±4.41) mm for oblique acupuncture; the safety depth of women was (44.17±7.80) mm for perpendicular acupuncture and (47.49±7.32) mm for oblique acupuncture. In the normal group, the safety depth of men was (47.72±5.06) mm for perpendicular acupuncture and (42.69±5.53) mm for oblique acupuncture; the safety depth of women was (44.63±5.85) mm for perpendicular acupuncture and (39.88±6.18) mm for oblique acupuncture. The safety depth of men and women for oblique acupuncture was longer than that for perpendicular acupuncture in the AAD group (<0.01); the safety depth of men and women for oblique acupuncture was shorter than that for perpendicular acupuncture in the normal group (<0.01). The safety depth of perpendicular and oblique acupuncture between men and women was not significant in the AAD group (>0.05); the safety depth of perpendicular and oblique acupuncture for men was longer than that for women in the normal group (<0.01). For men, the safety depth of perpendicular acupuncture in the AAD group was shorter than that in the normal group (<0.01), while the safety depth of oblique acupuncture in the AAD group was longer than that in the normal group (<0.01). For women, the safety depth of perpendicular acupuncture in the AAD group was similar with that in the normal group (>0.05), while the safety depth of oblique acupuncture in the AAD group was longer than that in the normal group (<0.01). CONCLUSION The safe depth of acupuncture at Yamen (GV 15) has significantly changed under AAD, so during the clinical acupuncture the needle insertion should be less than its safe depth.
