Xanthoma is a localized collection of tissue histocytes containing lipid. The majority of tendinous xanthomas probably occurs in the setting of hypercholesterolemia especially in bilateral Achilles tendon xanthomas. Xanthoma of the Achilles tendon is a rather rare, interesting orthopaedic condition that has important ramifications in internal medicine and dermatology because the lesion is associated with a specific disturbance of lipid metabolism. We experienced one case of normolipidemic and symptomatic Achilles tendon xanthoma. Surgical intervention was carried out for cosmetic and symptomatic reasons, the patient undergoing total resection and a reconstruction of the Achilles tendon by the combinedV-Y muscle flap and modified Lindholm technique.

With advances in techniques and instrumentation, the primary concern of microsurgeons has shifted from flap anatomy and survival toward flap refinement and donor-site function and aesthetics because flap survival rates have risen 96 percent. However, the problem still remains on regard that most flap has disadvantages that flap itself is too bulky or leaves unaesthetic scar to the donor site. These problems can be solved by using adipofascial flap instead of fasciocutaneous flap. The adipofascial flap not only has minimal donor site morbidity, but also can be retained thin. It seems that its advantages can be applied on soft tissue defect of exposed body part.

We experienced a case of impingement caused by a bone fragment which was impacted between acromion and humeral head in a child. The bone fragment came from antero-inferior glenoid fracture. Satisfactory clinical results and stability were obtained by arthroscopic bone fragment removal. In case that bone fragment is located in the upper shoulder joint and results in impingement, We must consider not only greater tubercle fracture but also glenoid fracture. Magnetic resonance imaging can assist in the preoperative diagnosis.

We report two cases of migration of K-wires from the acromioclavicular joint to the neck. A 73-year-old man complained of right shoulder pain for one month and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 27 years earlier. Another 56-year-old man complained of left shoulder pain and neck pain for 5 years and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 25 years earlier. In both cases, we took X-rays to look for the cause of shoulder pain and discovered broken and migrated K-wires in the neck. We removed the K-wires from the trapezius muscle and the paraspinal muscle respectively. K-wire fixation technique is simple and effective but should be followed up with X-rays periodically. In addition, we should warn patients of the possibility of migration of K-wire. And it is desirable for us to avoid using K-wire near major neurovascular structures like the sternoclavicular joint and the clavicle.

Brachial neuritis is a rare disorder of unknown etiology that affects the lower motor neurons of the brachial plexus. The clinical course is characterized by acute onset of severe pain followed by weakness and gradual recovery. Among diagnostic tests, electromyography may be useful. The brachial neuritis has been confused with other painful shoulder conditions. The awareness of this disorder helps prevent unwarranted diagnostic studies & treatment. The authors report a case of brachial neuritis.

Background: Common and effective treatments for calcific tendinitis involve needling procedures. However, it has been widespread practice to refer patients with calcific tendinitis, which is a predominantly orthopedic condition, to radiology department. The purpose of this study was to compare clinical and radiological outcomes after ultrasound-guided needling for calcific tendinitis between the orthopedics and radiology department. Methods: Seventy-seven shoulders (Group 1) and 38 shoulders (Group 2) treated in the radiology and orthopedic department, respectively. A fellowship-trained orthopedic surgeon and a musculoskeletal radiologist each performed the procedure of ultrasound-guided needle decompression with subacromial steroid injection. Clinical outcomes was evaluated using the visual analogue scale for pain (pVAS) and the American Shoulder and Elbow Surgeons (ASES) shoulder score before treatment and at each follow-up. The pre- and postneedling size and shape of the calcific deposits were compared between the two groups. Results: We analyzed a total of 56 shoulders for Group 1 and 32 shoulders for Group 2. The mean age and sex ratio of the patients no significantly different. We found that the mean decrease in the diameter of calcification between pre- and post-needling was 9.0 mm for Group 1 and 13.1 mm for Group 2; the difference was significantly larger in Group 2 than in Group 1. Both groups showed improved pVAS and ASES scores after needling but the extent of these improvements did not differ with the type of operator. Conclusions: Needling decompression performed by orthopedic surgeons could a viable option for the treatment of calcific tendinitis.

Purpose: The aim of this study was to evaluate the outcome and the effectiveness of local flaps in lower extremity reconstruction. Materials and Methods: We have performed lower extremity reconstruction with local flap in 14 cases (10 males and 4 females) from May 2006 to February 2008. The mean age was 40.1 years (range, 16~67). The defect site was the tibia in 5 cases, the ankle in 1 case and the foot in 8 cases. The local flaps were reverse flow sural artery flap in 7 cases, gastrocnemius flap in 3 cases, lateral supramalleolar flap in 2 cases, dorsalis pedis flap in 1 case and medial hemisoleus flap in 1 case. Results: All flaps were survived. Venous congestion was developed in 1 case of the rerverse flow sural artery flap but healed with secondary rotational flap. Other flaps were good without any complications. Conclusion: If we choose precisely indicated local flap in lower extremity reconstruction, the resultant coverage of defect would be excellent.

Background: In the past decade, the number of anatomic total shoulder arthroplasty (aTSA) procedures has steadily increased. Patients over 65 years of age comprise the vast majority of recipients, and outcomes have been well documented; however, patients are opting for definitive surgical treatment at younger ages.We aim to report on the effects of age on the long-term clinical outcomes following aTSA. Methods: Among the patients who underwent TSA, 119 shoulders were retrospectively analyzed. Preoperative and postoperative clinical outcome data were collected. Linear regression analysis (univariate and multivariate) was conducted to evaluate the associations of clinical outcomes with age. Kaplan-Meier curves and Cox regression analyses were performed to evaluate implant survival. Results: At final follow-up, patients of all ages undergoing aTSA experienced significant and sustained improvements in all primary outcome measures compared with preoperative values. Based on multivariate analysis, age at the time of surgery was a significant predictor of postoperative outcomes. Excellent implant survival was observed over the course of this study, and Cox regression survival analysis indicated age and sex to not be associated with an increased risk of implant failure. Conclusions: When controlling for sex and follow-up duration, older age was associated with significantly better patient-reported outcome measures. Despite this difference, we noted no significant effects on range of motion or implant survival. Level of evidence: IV.

Although Achilles tendinitis is a relatively common disease, tuberculous involvement of Achilles tendon is rare. We report a case of tuberculous Achilles tendinitis, which was successfully treated with chemotherapy and a combined surgical procedure (Achilles tendon parital excision and FHL tendon transfer).

Pigmented villonodular synovitis (PVNS) in ankle is relatively uncommon. This disorder results in increased proliferation of synovium causing villous or nodular changes containing histiocytes, fibroblasts, multinucleated giant cell, and hemosiderin. PVNS is classified into two different type : localized and diffuse. Diffuse type of PVNS in ankle is more common than localized type. Also, recurrence of diffuse type is more frequent. We report a case of diffuse type of PVNS which was recurred soon after the excision.
