    Giant-cell tumor of the hand
    Ozalp, T; Yercan, H; Oku, G; Ozdemir, O; Coskunol, E; Bégué, T; Calli, I
    Purpose of the study Giant-cell bone tumors are benign but have great potential for recurrence. Frequently observed in epiphyseal areas of tubular bones, these tumors are rarely found in hand localizations. We examined the characteristic features of giant-cell tumors of the hand and analyzed the pertinence of surgical treatment. We noted complications, consequences of recurrence and later operations on the same tumor site in five cases. Case reports Five patients treated between 1973 and 2000 for giant-cell tumors involving the hand bones were reviewed retrospectively, Mean age was 41.6 years and mean follow-up was 7.8 years. The surgical procedure was curettage for two, curettage with bone graft for two and amputation for one. The Enneking score was noted. Results Pain was the main symptom, with local swelling in several cases. At 7.8 years follow-up recurrence was noted for four of the five tumors. Two patients were treated for a second recurrence. Amputation of the forearm was required for one recurrence affecting soft tissue. Mean time between two consecutive recurrences was three months. In all six episodes of recurrent tumor were treated. These five patients had a total of ten operations. There were no cases of metastasis nor multicentric foci. Discussion Treatment of giant-cell tumors involving the hand bones is designed to eradicate the tumor and also protect hand function while keeping in mind the aggressive nature of these benign tumors. Surgical alternatives for radical treatment can include wide resection, resection of the ray and amputation.

    The analysis of functional and radiographic outcomes of conservative treatment in patients with low lumbar burst fractures
    Erkan, S; Tosyali, K; Özalp, T; Yercan, H; Okcu, G
    Introduction: Burst fractures of the low lumbar spine constitute approximately one percent of all lumbar fractures. There is still no consensus on the optimal treatment of low lumbar burst factures. We aimed to evaluate the functional and radiographic outcomes of conservative treatment in patients with low lumbar burst fracture. Methods: 15 patients (11 males, 4 females; mean age 32 +/- 8) who had low lumbar spine burst fracture treated with a custom-moulded thoracolumbosacral orthosis (TLSO) with a thigh extension were enrolled. The mean follow-up period was 22 +/- 6 months. 14 patients were neurologically intact and one had isolated nerve root injury. There were 24% type A fractures and 76% type B fractures according to the Denis classification system. Functional outcomes were evaluated by using Oswestry Disability Index (ODI), Short-Form 36 (SF-36) and Visual Analogue Scale (VAS). Radiographic outcome was analyzed by measuring anterior vertebral height loss, kyphosis angle, amount of canal retropulsion. Functional and radiographic outcomes were reviewed initially and at 1, 3, 6, 12 months, and at the latest follow-up. Functional and radiographic improvements were analyzed statistically. Results: The mean bracing period was 11.9 +/- 1.7 weeks. The mean initial ODI, SF- 36, and VAS score of the patients was 78.3 +/- 9.6, 23.7 +/- 8.9, and 8.7 +/- 0.7, respectively. The mean ODI, SF- 36, and VAS score of the patients at the final follow-up was 26.4 +/- 6.5, 68.1 +/- 11.2, and 2.8 +/- 1.7, respectively. The improvement in functional outcomes was measured to be significant (p < 0.05 for ODI, SF-36 and VAS). The mean initial anterior vertebral height loss, kyphosis angle, amount of canal retropulsion was found to be 27.2% +/- 9.6%, -6.8 degrees +/- 3.28, 37.4% +/- 10.2%, respectively. The mean anterior vertebral height loss, kyphosis angle, and amount of canal retropulsion at the final follow-up was 23.1% +/- .6.7%, 4.2 degrees +/- 2.48, 19.6% +/- 7.7%, respectively. Among the radiographic outcomes, only the amount of canal retropulsion improved statistically (p = 0.042). Conclusion: Conservative treatment using a custom-moulded thoracolumbosacral orthosis with a thigh extension is a safe and effective method in patients with low lumbar spine burst fractures and can improve functional and radiographic outcomes.
