Freiberg disease is a relatively rare osteochondrosis of metatarsal head, which usually involves the 2nd metatarsal of adolescent females. Various open surgical treatments have been recommended; arthrotomy and removal of loose body, dorsiflexion osteotomy and resection of the metatarsal head. Arthroscopic treatment for Freiberg disease has a merit of shortening the recovery period and reducing the postoperative stiffness. We report a case of early stage Freiberg disease treated with metatarsophalangeal arthroscopic excision of loose body and debridement of the 2nd metatarsophalangeal joint.

Purpose : This study was conducted to assess the surgical outcomes of limbal lensectomy with or without anterior vitrectomy for the management of lens subluxation. Materials and Methods : The medical records of 20 consecutive patients (33 eyes) with lens subluxation who had undergone limbal lensectomy with or without anterior vitrectomy from February 1999 to January 2004 were retrospectively reviewed. Results : All the patients, except one high axial myopic patient, were implanted with scleral sutured posterior chamber intraocular lens. We evaluated the preoperative, postoperative visual acuity and postoperative complications and compared the results in group I (limbal lensectomy with anterior vitrectomy, 27 eyes) to those in group II (limbal lensectomy without anterior vitrectomy, 6 eyes). The preoperative best-corrected visual acuity was 0.21 and postoperative best-corrected visual acuity was improved by 2 lines or more in all 27 eyes in group I, and in 5 eyes in group II (p>0.05). The most frequent postoperative complication was intraocular lens dislocation in four eyes (14.8%) in group I alone. No retinal detachment occurred in either group, even in patients with high myopia. Conclusion : Limbal lensectomy without anterior vitrectomy improved visual acuity similarly to limbal lensectomy with anterior vitrectomy without significant increase of postoperative complications. This results of this study suggest that anterior vitrectomy is not necessarily required for the management of lens subluxation.

Purpose : We evaluated the results of the arthroscopic treatment of nine cases of synovial chondromatosis in the knee joints. Materials and Methods : From June 1989 to September 1999, eight patients nine cases with synovial chondromatosis involving knee joints underwent arthroscopic total synovectomy and removal of loose bodies. There were 6 females and 2 males. The average age at surgery was 44.1 years(range, 20-57 years). The average follow-up period was 5.9 years (range, 2.5-7.3 years). All cases had pain and swelling and two cases had locking preoperatively. Flexion contracture was found in three cases. Results : Pathologic finding revealed Milgram I in one case, Milgram II in six cases and Milgram III in two cases. There were six cases of generalized synovial hypertrophy and one case of localized type. All patients had symptomatic relief by arthroscopic total synovectomy and loose body removal. Second arthoroscopic surgery was performed in one patient due to recurred lesions 11 months after the primary surgery. Conclusion : Clinical results of the synovial chondromatosis with arthroscopic total synovectomy and loose body removal were satisfactory. Arthroscopic total synovectomy was also effective for the recurred case.

To evaluate clinical results of silicone oil injection for retinal detachment. The 45 eyes of 44 patients underwent vitrectomy and silicone oil injection from 1999 to 2002. 1.There were no history of previous retinal surgery and ocular trauma. In 24 of the 45 eyes(53%) visual acuity increased and stabilized in 18 of the 45 eyes(40%). 2. 1 of 16 eyes(6.3%) had recurred retinal detachment after silicone oil removal. 3. Final retinal reattachment was achieved in 44 eyes(97%). Postoperative complications were cataract(16 eyes), glaucoma(10 eyes), emulsification of silicone oil(5 eyes), keratopathy(2 eyes) and recurrent retinal detachment(1 eye). These results show that silicone oil injection for primary retinal detachment yields a high rate of anatomic success and the good visual outcome

Purpose: We wished to evaluate the clinical usefulness of ultrasound, when loose body is palpated and is shown radiographically in knee. Material and Methods: Twenty-five knees of twenty-two patients with loose body in knee radiographically from March, 2007 to July, 2009 were involved in this study, there were 8 males and 14 females, there were 11 right knees, 8 left knees and 3 both knees, the average age was 56.3 years (range, 32~76 years). The location of loose bodies were 13 cases at suprapatella pouch, 1 case at infrapatella anterior compartment and 11 cases at posterior compartment. In loose bodies of suprapatella pouch, we examined the mobility of loose bodies longitudinally with ultrasound placed at superior patella pole while flexing and extending the knee. In loose bodies of infrapatella anterior and posterior compartment, we examined the mobility of loose bodies longitudinally and transversely with ultrasound while flexing and extending the knee. Results: All cases of suprapatella pouch and infrapatella anterior compartment were diagnosed to movable loose bodies and were removed surgically, all cases of posterior compartment were diagnosed to immovable loose bodies and were not removed. Conclusion: When we determined the surgical removal according to mobility of loose body in knee, ultrasound may be helpful clinically.

A 20-year-old patient who got injured on his right big toe and complained pain visited to our hospital 9 months ago. Before the patient transferred to our hospital, plain radiographs were obtained at a private hospital and the patient underwent conservative treatment with uncertain diagnosis. However, the symptom was not improved, and he continued to complain intra-articular pain on his interphalangeal joint of big toe during plantarflexion or dorsiflexion. On plain radiographs of our hospital, we observed small bone fragment in his interphalangeal joint of the big toe. On the ultrasonographic images, two loose bodies in the interphalangeal joint were found. Then, we removed the loose bodies as surgical treatment, and the symptom was subsided completely. The purpose of this study is to report the ultrasonographic finding of the loose bodies of interphalangeal joint of the big toe.

Purpose: To report a case of a 60-year-old female with rhegmatogenous retinal detachment, presenting with suprachoroidal hemorrhage after vitrectomy. Case summary: A 60-year-old woman visited our clinic complaining of floaters, flashing, and blurred vision. Best-corrected visual acuity was 0.1 in her left eye, and fundus examination of her left eye revealed macula-involved retinal detachment with a retinal break at the superotemporal quadrant. She underwent cataract surgery, 23-gauge transconjunctival sutureless vitrectomy, and 14% C3F8 gas tamponade under general anesthesia. One hour after anesthesia recovery, she suddenly complained of severe pain in her left eye. The intraocular pressure measured after removal of the pressure patch from her left eye was as high as 58 mmHg. Her ocular pain improved spontaneously within 10 minutes, and the intraocular pressure decreased to 8 mmHg. Fundus examination of her left eye revealed a reddish-brown raised lesion, suggesting suprachoroidal hemorrhage. She was placed in a prone position with a pressure patch over her left eye. Bleeding through the sclerotomy site was observed 1 day after surgery. Subsequently, hemorrhagic choroidal detachment of her left eye continued to decrease without deterioration. Three weeks after surgery, the patient received an intravitreal injection of 100% C3F8 gas into her left eye. At 3 months after surgery, best-corrected visual acuity had improved to 0.8 in her left eye, and the retina was stable. Conclusions: Suprachoroidal hemorrhage may be suspected in a patient complaining of severe ocular pain after vitrectomy.

Synovial chondromatosis is an uncommon condition, and the involvement of the shoulder joint is rare. A 15 year old female patient presented to author's institution for right shoulder pain. We checked the plain radiographs and MRI. And they showed that a diagnosis of synovial chondromatosis in the shoulder, and they also demonstrated that the disease involved the bicipital tendon sheath as well as glenohumeral joint. We removed all loose bodies with total synovectomy by arthroscopic procedure, and a miniopen procedure for the lesions of biceps tendon sheath. Arthroscopic treatment affords excellent visualization of the shoulder joint with less morbidity. However, with current arthroscopic techniques, it is difficult to manage the synovial chondromatosis of biceps tendon in bicipital groove. The authors suggest that the complete elimination of synovial chondromatosis involving shoulder requires a mini-open procedure for the lesions of biceps tendon sheath in addition to the arthroscopic resection of the affected synovium and loose body removal in the glenohumeral joint.
