PURPOSE: It has been studied prognostic factors about secondary displacement after conservative treatment of the distal radius fracture, but each study showed different results. Authors retrospectively evaluated factors known to be involved secondary displacement of the distal radius fracture to determine its significance. METHODS: One hundred eighteen cases of the radiographically unstable distal radius fractures that closed reduction was adequately performed were retrospectively studied and the radiographic images were taken at 1, 2, 3, 4, 6 weeks after closed reduction. During follow-up, dorsal tilt more than 15°, volar tilt more than 20°, ulnar positive variance more than 4 mm, radial length less than 6 mm, radial inclination less than 10° were thought of the loss of reduction. RESULTS: In 41 cases (34.7%), the loss of reduction occurred. Sex, intra-articular fracture, dorsal and volar comminution, concomitant ulnar fracture and involvement of the distal radio-ulnar joint were statistically not significant. Analysis results of the binomial logistic regression model were as follows: age (p=0.003), radial shortening (p=0.010) and ulnar positive variance (p=0.010) were statistically significant as the predictive prognostic factors. Analysis results of the multinomial logistic regression model showed age (p=0.006) as an only statistically significant factor. CONCLUSION: As the predictive prognostic factors for development of secondary displacement after conservative treatment of the unstable distal radius fracture, age was determined as most significant factor. Also radial shortening and ulnar positive variance were thought of the predictive factors for secondary displacement.

Snapping hip syndrome is a relatively common problem that can be easily managed with conservative treatment. This syndrome can be divided into external, internal and intra-articular types. Internal snapping hip syndrome is the rarest amongst these and its etiology is not well understood. We report a unique case of osteochondroma arising from the anterior inferior iliac spine (AIIS), which caused the internal snapping hip syndrome with hip pain and restriction of activity. This rare case of snapping hip syndrome from the AIIS was treated surgically and the symptoms completely disappeared after excision of the tumor.

Anterior interosseous nerve is purely a motor nerve and supplies flexor pollicis longus, flexor digitorum profundus to the index finger, and pronator quadratus. The etiology and treatment option of anterior interosseous nerve syndrome remain controversial. Bilateral involvement of the anterior interosseous nerve have been described rarely; however, we found no reported case of nonsimultaneous bilateral anterior interosseous nerve palsy associated with the entrapment neuropathy. We present the unique case of delayed anterior interosseous nerve syndrome, 3 years 5 months following an identical event in the opposite extremity and literature review.

PURPOSE: As well as patient survival, the restoration of postoperative function such as ambulation is important in limb salvage operations for treatment of malignant bone tumors involving the proximal femur. The authors analyzed clinical outcomes of limb salvage operations using tumor prostheses for metastatic or primary malignant bone tumors in the proximal femur. MATERIALS AND METHODS: From February 2005 to January 2014, 20 cases (19 patients) with malignant bone tumor involving the proximal femur with pain or complicated pathologic fracture were treated with segmental resection and limb salvage operations with tumor prostheses. Mean age was 63.1 years (range 35-86). Fourteen patients were male and six ones were female. The mean follow-up period was 20 months (1-94 months). There were 15 cases of metastatic bone tumor, 4 cases of osteosarcoma, and 1 case of multiple myeloma. The primary tumors of the metastatic bone tumors included 4 lung cancers, 3 hepatocellular carcinomas, and 3 renal cell carcinomas. Other primary tumors were breast cancer, thyroid cancer, colon cancer, prostate cancer, and malignant spindle cell tumor, each in 1 case. Modular tumor prostheses were used in all cases; (Kotz's(R) Modular Tumor prosthesis (Howmedica, Rutherford, New Jersey) in 3 cases, MUTARS(R) proximal femur system (Implantcast, Munster, Germany) in 17 cases). Perioperative pain was assessed with Visual Analogue Scales (VAS). Postoperative functional outcome was assessed with Musculoskeletal Tumor Society (MSTS) grading system. RESULTS: Out of 20 cases (19 patients), 11 cases (10 patients) survived at the last follow-up. Average postoperative survival of the 9 deceased patients was 10.1 months (1-38 months). VAS score improved from pre-operative average of 8.40 (5-10) to 1.35 (0-3) after operation. Average postoperative MSTS function score was 19.65 (65.50%, 7-28). The associated complications were 2 local recurrences, 3 hematomas, 3 infections, 2 scrotal swellings, and 1 dislocation. There was no case of periprosthetic fracture or loosening. CONCLUSION: Limb salvage operation with tumor prosthesis is an appropriate treatment for early pain reduction and functional restoration in malignant bone tumors in the proximal femur with pain an/or complicated pathologic fractures.

Clear cell chondrosarcoma is a very rare malignant bone tumor that shows a strong predilection for the epiphysis or metaphysis of long bones. Many studies have reported that the proximal end of the femur is the most commonly affected site, followed by the proximal end of the humerus. Histopathologically, tumor cells of this type have centrally located round nucleoli with clear cytoplasm and a distinct cytoplasmic membrane. Generally, clear cell chondrosarcomas is not confused with conventional chondrosarcomas. However, when it involves the diaphysis in long bones, diagnosis can be hindered, as only three reports of this exist in the literature. We report herein an unusual case of clear cell chondrosarcoma of the tibial diaphysis in a 42-year-old male.

Treatment of giant cell tumor of distal radius can be treated in several ways according to the aggressiveness of the tumor. The management of giant cell tumor involving subchondral bone of the distal radius has always been a difficult problem and whether preserving joint function should be considered. In these circumstances, wrist arthroplasty using free vascularized fibular head grafting can be considered as one of available options to preserve the wrist joint motion. However, the reports for final outcomes of wrist arthroplasty using vascularized fibular head have been variable and there have been several debates about its techniques. The purpose of this article is to discuss the several considerations in wrist arthroplasty using free vascularized fubular head graft for giant cell tumors of the distal radius.

PURPOSE: The aim of this study is to report on the results and discuss the role of free flap followed by ipsilateral vascularized fibular transposition (IVFT) for reconstruction of large bone and soft tissue defect combined with infection by open tibia fracture. MATERIALS AND METHODS: During the research period, lasting from December 2002 to June 2008 (Kyung Hee University Medical Center), data were collected from three patients who underwent IVFT after free flap. We analyzed the successiveness and persistency of the infection using free flapping, bone union, and hypertrophy between transposed fibula and tibia. RESULTS: Regarding free flap, successive results were observed in all examples. In the final follow-up results, transposed fibulas all survived, having hypertrophy similar to that of adjacent tibia. CONCLUSION: Reconstruction of tibia defect with free flap followed by IVTF is a useful and safe method for avoidance of the potential risk of infection for patients with a large tibial bone defect and soft tissue defect associated with infection.

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.

Glomus tumor is a kind of vascular tumor that arises from the glomus body, which regulates skin temperature and is placed in the skin and the subcutaneous area. It is a benign tumor that usually presents in the subungal area. It is relatively common in areas other than the fingers, but its occurrence in peripheral nerves is known to be comparatively rare. We report our experience with a case of glomus tumor arising from the brachial plexus, a rare site of occurrence for glomus tumors.

BACKGROUND: Scar tissue formation is the major cause of failure in peripheral nerve surgery. Use of a hyaluronic acid-carboxymethylcellulose (HA-CMC) membrane (Seprafilm) as a solid anti-adhesion barrier agent is one of the therapeutic approaches to reduce postoperative scar tissue formation. However, a solid membrane may not be suitable for repair of a weak peripheral nerve site. This study examined the effect of HA-CMC solution on perineural scar formation after peripheral nerve repair in rats. METHODS: The sciatic nerves of 40 rats were transected and then immediately repaired using 10-0 nylon. The nerves were divided randomly into two groups. Saline and HA-CMC solution were applied topically to the nerve repair sites in the control and experimental groups, respectively. Reoperation was performed at 3, 6, 9, and 12 weeks to assess scar tissue formation. The assessment included the quality of wound healing, presence of perinueral adhesion, cellular components of the scar tissue, thickness of the scar tissue and histomorphological organization of the repair site. RESULTS: Topical application of the HA-CMC solution significantly decreased the macroscopic nerve adherence score and the numbers of the cellular components such as fibroblasts and inflammatory cells (p < 0.05, Mann-Whitney U-test). The scar tissue formation index was significantly lower in the experimental group at 12 weeks than that in the control group (p < 0.05, Mann-Whitney U-test). The grading scores of the histomorphological axonal organization at the repair site were significantly higher in the experimental group than those in the control group at 12 weeks (p < 0.05, Mann-Whitney U-test). No evidence of wound dehiscence or inflammatory reactions against the HA-CMC solution was noted. CONCLUSIONS: Topical application of a HA-CMC solution is effective in reducing the perineural scar formation and adhesion after sciatic nerve repair in rats, and is effective in promoting peripheral nerve regeneration at the repair site.

Secondary osteosarcoma has a relatively higher incidence in middle aged persons than in children. Radiation-induced osteosarcoma occurs in approximately 1% of patients who have been treated with more than 2,500 cGy. The time interval from radiation to onset of secondary osteosarcoma is approximately 10 to 15 years. A 51-year-old female who have been treated with radiation for angiomyxoma was hospitalized due to right hip pain. She had a minor trauma 2 weeks prior to hospitalization. A day before hospitalization, she experienced a second trauma by fall, and then, severe hip pain developed. A radiograph of the patient showed femoral neck fracture with sclerotic change of fractured margin. We diagnosed the patient as having a neglected femoral neck fracture and treated it with closed reduction using cannulated screw fixation. At 6 months post-surgery, the patient had residual pain of the right hip and we could find overproduced callus at the fracture site. Through further evaluation, we diagnosed this as secondary osteosarcoma with pulmonary metastasis. We report this case to make a warning about a misdiagnosed osteosarcoma as a simple femoral neck fracture.

During below knee amputation, the amputation stump must be covered with well-vascularized and sensate soft tissue. Many flaps can be used for this purpose, but available reconstructive options are limited. We performed reverse flow ALT flap elevation on two patients with below knee amputations to reconstruct defects in the stumps. The sizes of the defects in the stumps were 4x16 cm and 5x5 cm, respectively. The most distal portion of the defects were located 20 cm and 16 cm lateral to the knee joint in a curve, respectively. The size of the elevated flap was 5x18 cm for case 1 and 18x10 cm for case 2. The respective pivot points of the pedicles were 7 cm and 6 cm above the patella and the respective lengths of the pedicles were 17 cm and 16 cm. In both cases, venous congestion occurred on the second postoperative day and the flap distal to 10 cm or more from below the knee joint was necrotized at the second postoperative week. Surgeons should be cautious when using a reverse ALT flap to reconstruct a soft tissue defect located 10 cm or more distal from below the knee joint. Since a pedicle longer than 15 cm may develop partial necrosis of the flap, simultaneous application of antegrade venous drainage is recommended.

19 years old girl presented with bilateral 1, 4th brachymetatarsia. We have used an autograft interposition technique to lengthen the brachymetatarsia involving first and fourth metatarsal. The technique was to graft the bone fragment from the relatively long second and third metatarsal bone to be used as an autograft to the short first and fourth metatarsal bone. The method is superior in not having the necessity of a long term external fixator which is needed using callotasis method and in also avoiding the inconvenience of performing an allograft. Absence of donor site complication during autograft from iliac bone is also an advantage to be mentioned. Our technique can therefore be ascertained as a successful method in both cosmetic results and improvement of symptoms including reduction in length of recovery.

PURPOSE: Finger is the one of the common site of open fracture, and it causes osteomyelitis of the phalanges. The purpose is to analyze the efficacy of management of chronic osteomyelitis in hand phalanges with mini external fixatior. METHODS: From March 2002 to December 2008, we experienced 8 cases of chronic osteomyelitis in hand phalanges. One case was a phalangeal infection after toe transfer, and three cases were the epiphyseal injury of phalanx in children. All cases used mini external fixator. Soft tissue coverage was performed using rotational flap in 4 cases, pedicled flap in 3, and cross finger flap in 1. Additional operation was required a mean of 2.2 times per patients. RESULTS: All cases achieved soft tissue coverage, eradication of osteomyelitis and bony union. However, five cases had bone shortening due to severe infection, and two cases showed mild growth disturbance. CONCLUSIONS: Mini external fixator is effective in management of osteomyelitis occurred in hand phalanges.
