An osteoid osteoma is a benign bone tumor. It is most commonly found in the femur and tibia but only 5% to 15% occurs in hand. Osteoid osteoma of carpal bone has vague nature of symptoms including spontaneous dull aching causing delayed diagnosis and the late treatment. We had a patient with an osteoid osteoma of the capitate bone presenting with tenosynovitis. We present clinical and radiological findings including magnetic resonance imaging, surgical result, and a review of the current literature.

PURPOSE: This study was performed to investigate the degree of symptom improvement after removal of bone fragment in patients with deformed pisiform bone associated with tendonitis of flexor carpi ulnaris. METHODS: Pisiform bone fragment removal was performed in 12 patients who had failed conservative treatment from January 2008 to December 2011. They were followed up at 2 weeks, 1 month, 2 months, 6 months, and 12 months after surgery. Their symptoms were assessed with Green score. RESULTS: Eleven of 12 patients who underwent bone fragment removal showed symptom improvement. Symptoms worsened in 1 patient due to pain and restricted range of motion caused by postoperative scar. CONCLUSION: The results of this study suggest that removal of bone fragment may be an effective treatment in patients with tendonitis of flexor carpi ulnaris accompanied by pisiform bone deformity whose pain does not improve with conservative management.

PURPOSE: We reported results of percutaneous multiple K-wire fixation technique without passing through the joint in patients with a hand fracture. METHODS: We evaluated a total of 116 cases in 94 patients who underwent percutaneous multiple K-wire fixation on dorsal cortex over a 10-year period between 2001 and 2010. The treatment outcomes were evaluated based on total active motion (TAM), as proposed by Widegrow. RESULTS: Our clinical series of patients achieved good functional outcomes. Of total patients, 89% (84/94) had excellent TAM, 2% (2/94) did good TAM and 9% (8/94) did poor TAM. Postoperatively, our clinical series of patients had such a good compliance as to achieve a TAM of >181degrees when performing the early active movement. There were no notable postoperative complications during the follow-up period. CONCLUSION: Our results indicate that percutaneous multiple K-wire fixation technique without passing through the joint from normal bone density patients is effective in providing the rigid fixation. Thus, our patients could perform the early movement as promptly as possible and maintaining the full mobility of the rest of the hand.

PURPOSE: To determine the relationship between the length of distal locking screws and diaphyseal screws in volar plate fixation of distal radius fractures. METHODS: A retrospective review was performed of 169 patients who underwent volar locking plate fixation for treatment of distal radius fractures. All patients received 2.4 mm LCP volar extra-articular distal radius plate (DePuySynthes). The length of the diaphyseal screw which was placed in the elongated hole was correlated with the length of a distal locking screw from radial most (D1) to ulnar most (D4). We also evaluated distal screw penetration of the dorsal cortex and plate removal rate. RESULTS: The length of the diaphyseal screw which was placed in the elongated hole strongly correlated with the length of a distal locking screw. Average D1 screw length was 2 mm longer than the diaphyseal screw, and average D2 screw length was 4 mm longer than the diaphyseal screw. D3 and D4 screw were 6 mm longer than the diaphyseal screw. Plate removal was necessary in 13 patients (8%) due to screw irritation. These patients had significantly longer screws than average. Flexor or extensor tendon ruptures did not occur in this cohort. CONCLUSION: The length of the distal locking screws can be estimated with the length of the diaphyseal screw. This information may help surgeons to select the adequate length of distal locking screws during volar plating of distal radius fractures.

PURPOSE: We present the clinical and radiological results of open reduction and internal fixation for scaphoid fracture with retrograde headless screw fixation via dorsal approach. METHODS: This study carried out a survey targeting 15 patients who have a retrograde headless screw fixation on nonunion of scaphoid fracture without previous operation, 2 patients who have a retrograde headless screw fixation on nonunion of scaphoid fracture with previous operation and 8 patients who have a trans-scaphoid perilunate dislocation. We figured out a mechanism of injury, and clinical symptom, radiologic findings. The surgery was done with open dorsal approach which is retrograde headless screw fixation internally, with or without bone graft. We analyzed the result by Maudsley method, in terms of bone union, duration for union, radiologic finding, clinical outcomes. RESULTS: After surgery, 22 of 25 patients had union result on fracture and other 3 patients had nonunion result. It took 12 weeks to achieve bone union on average. Based on radiograhs, we had one case of partial avascular necrosis of proximal fragment without clinical symptoms. We had one case of each scaphoid nonunion without previous operation, with operation and trans-scaphoid perilunate dislocation had arthritic change and non-symptomatic nonunion result. In terms of clinical outcome, 22 patients showed satisfactory results and 3 patients had slight limitation of range of motion. CONCLUSION: Retrograde headless screw fixation with or without bone graft for the treatment of scaphoid fracture is recommendable.

PURPOSE: The purpose of this study was to evaluate clinical results for open reduction and internal fixation of unstable extraarticular metacarpal fractures using low profile titanium plates. METHODS: Sixty-two consecutive patients (76 metacarpals) with unstable extraarticular metacarpal fractures who prospectively underwent internal fixation with plating were enrolled. Minimum follow-up was 1 year. There were 48 males and 14 females; average age was 39 years (range, 15-71 years). The location of the fractures was shaft in 65 metacarpals and the type was transverse in 22 cases, oblique in 46 cases, and communited in 8 cases. Of the 62 patients, 11 were open; 9 of these had additional soft tissue injury. The surgical outcome was assessed by clinical and radiographic outcomes and complications. RESULTS: Bone union was successfully achieved in all patients on the average period of 6.4 weeks. The final range of total active motion was excellent for 64 cases, good for 6 cases, fair for 5 cases, and poor for 1 case. Postoperative complications occurred in 9 patients (15 metacarpals). Statistical analysis revealed that patient age, occupation, multiple metacarpal fractures, and soft tissue injury were significantly correlated with incidence of complications at last follow-up. CONCLUSION: Low profile titanium plating showed the low complication rate and good results in treating unstable extraarticular metacarpal fractures.

PURPOSE: To evaluate clinical and radiological results of SCHT(scapho-capito-hamato-triquetral) fusion in Lichtman stage IIIB or IV Kienbock's disease. MATERIALS AND METHODS: The result of eight cases, operated and followed since December 2002, were analyzed retrospectively. The indication of SCHT fusion was the advanced Kienbock's disease, in Lichtman stage IIIB or IV, with severe fragmentation of lunate. The fragmented lunate was excised and the intercarpal joint between scaphoid and capitate, capitate and hamate, hamate and triquetrum were fused with joint resection, bone graft and multiple K-wires, to make an horse-shoeshaped carpal bone block. The clinical results were evaluated by wrist pain, ROM, any radiologic changes of wrist at last follow-up and Kuschner's method. RESULTS: There were 3 cases of Stage IIIB and 5 cases of stage IV. Mean follow-up period was 28.9 (range 15-53) months, and mean age at the time of operation was 49.4 (range 33~66) years. Two cases were minus ulnar variance, 4 cases were positive and 2 cases were neutral. The wrist range of motion was decreased from 121.8degreesto 90.6degrees(25%). Carpal height ratio was decreased in 1 case. The last follow-up results according to Kuschner's method revealed 4 excellent, 3 good and 1 fair. CONCLUSIONS: SCHT fustion was considered as one of the favorable salvage procedure for the advanced Kienbock's disease. However, biomechanical study using cadaver, long-term follow-up & accumulation of more cases would be needed to confirm its definitive usefulness in the future.

PURPOSE: The purpose of this study is to determine whether the three-dimensional computed tomography (3D-CT) images would increase the reliability of fracture classification and influence treatment plan of distal radius fractures. MATERIALS AND METHODS: Four independent observers evaluated radiographic images of thirty patients with distal radius fractures. The fracture classification has been performed based on (1) AO classification, (2) Fernandez classification, (3) Frykman classification. And then treatment plan was planned based on (1) closed reduction with Sugar-tong splint, (2) closed reduction with pinning, (3) closed reduction with external fixator, (4) open reduction with plate (volar approach), (5) open reduction with plate (dorsal approach). Two rounds of evaluation were compared regarding: (1) simple radiographs alone, and (2) simple radiographs and 3D-CT together two weeks after that. This cycle was then repeated to assess intraobserver reliability. RESULTS: 3D-CT improved the intraobserver and interobserver reliability regarding the fracture classification and treatment plan. And the addition of 3D-CT to simple radiographs influenced treatment recommendations, resulting in a significantly greater number of decisions for an open approach (p<0.05, McNemar test). CONCLUSIONS: 3D-CT is a reliable tool of fracture classification and improves treatment plan of distal radius fractures.

PURPOSE: Radial shortening osteotomy and ulnar lengthening osteotomy for decreasing axial loading have been known to treatment for avascular necrosis of lunate bone. The purpose of this study was to evaluate the clinical outcomes of radial shortening osteotomy for Lichtman stage III Kienbock disease. MATERIALS AND METHODS: Between December 2001 and October 2008, thirteen patients with Kienbock disease underwent a radial shortening osteotomy at our institution. On the basis of Lichtman classification, six had stage IIIA and seven had stage IIIB. Radiographic measurement of the ulnar variance and the carpal height ratio were assessed preoperatively and at the follow-up. Patients were examined for wrist pain, range of motion at flexion and extension and grip strength both preoperatively and postoperatively. The clinical outcomes was evaluated through the modification of Evans scoring system. RESULTS: All thirteen had maintained the preoperative stage at the follow-up. In ulnar variance, negative variance was seven. The carpal height ratio was increased mean 0.018 at the follw-up. Pain in VAS was improved mean 3.6 at the follow-up. In range of motion of wrist flexion-extension, in the eleven which had limitation of motion preoperatively, all eleven showed improvement. In grip strength, among the ten which had decreased preoperatively, eight showed improvement and two showed no change at the follw-up. The clinical outcomes were good in eight, fair in three and poor in two. Among the five, negative ulnar variance of stage IIIB, three had good, two had fair clinical outcomes. CONCLUSIONS: We found that radial shortening osteotomy can prevent disease progression, also show good clinical results for stage IIIB Kienbock disease as well as stage IIIA.
