    (2004) Ozalp T.; Yercan H.; Kurt C.; Ozdemir O.; Coşkunol E.
    OBJECTIVES: Giant-cell tumors of the tendon sheath localized in the hand or wrist were retrospectively reviewed with respect to diagnosis, surgical treatment, and postoperative complications. METHODS: During a 21-year period, a total of 141 patients (83 females, 58 males; mean age 37.5 years; range 6 to 77 years) underwent surgery for 146 lesions that developed in the hand (n=134) or the wrist (n=12). Involvement was on the right side in 77 patients, and on the left side in 64 patients. The mean follow-up period was 3.5 years (range 6 months to 11 years). RESULTS: On presentation, the most common symptom was the presence of a painless soft tissue mass. The most frequent localization was the volar part (76%) of the second (27%) and the third (24) fingers, or the proximal phalanx (57%). Forty per cent of tumors were encountered at ages between 30 and 50 years. The duration of symptoms ranged from one month to five years and the highest number of presentations fell within the first six months. In eighteen patients, radiologic studies showed osseous involvement, being cortical sclerosis in 12 patients, and erosion in eight patients. Postoperative complications included digital nerve injuries in four patients, superficial infection in three patients, and joint stiffness in 12 patients. Twenty-three patients (16%) developed recurrences within a mean of 3.7 years (range 2 months to 7 years). CONCLUSION: Taking high rates of recurrences into consideration, surgery for giant-cell tumors of the tendon sheath requires wide surgical exposure, attentive skills, and the use of magnification.

    Long-term results of autograft and allograft applications in hand enchondromas; [El yerleşimli enkondromlarin tedavisinde otogreft veya allogreft uygulamalarinin geç dönem sonuçlari.]
    (2004) Yercan H.; Ozalp T.; Coşkunol E.; Ozdemir O.
    OBJECTIVES: We evaluated the long-term results of treatment with curettage followed by an autograft or allograft application in patients with enchondroma of the hand. METHODS: Within a 15-year period, 76 patients (41 males, 35 females; mean age 32 years; range 14 to 47 years) were operated on for enchondroma of the hand. Following curettage of the lesion, reconstruction of the defect was made either by an autograft obtained from the iliac crest (n=76) or by a dehydrated cancellous allograft (n=15). The diagnosis was histologically confirmed in all the cases. Functional and radiographic results were assessed according to the Enneking scoring system and the Tordai classification system, respectively. The mean follow-up periods were 13.5 years (10-22 years) and 7.4 years (6-11 years) in autograft and allograft applications, respectively. RESULTS: Consolidation of the autografts took a mean of 38 days and maximum grasp force was obtained in a mean of 46 days. These periods were 51 and 55 days, respectively, for the allografts. Functional results were excellent/very good in 64%, good in 23%, and poor in 13.1% with autografts; radiographically, 78.7% of the patients were in group I, 18% were in group II, and 3.3% were in group III. Of the allograft group, the results were excellent/very good in 66.7%, good in 26.7%, and poor in 6.7%. Radiographically, 80%, 13.3%, and 6.7% of the patients were classified in group I, II, and III, respectively. There were two recurrences in the autograft group, while one patient, in the allograft group, who had multiple enchondromatosis required a ray amputation because of malignant transformation. CONCLUSION: Autograft and allograft applications seem to yield similar success rates in the treatment of enchondroma of the hand.

    Free radial forearm flap transfer for the reconstruction of the Achilles tendon and soft tissue defect: A case report; [Aşil tendon ve yumuşak doku defektinin rekonstrü ksiyonunda serbest radial önkol flep transferi: Olgu sunumu]
    (2005) Coşkunol E.; Özdemir O.; Özalp T.
    Reconstruction of the soft tissue defects around the Achilles tendon is a difficult challenge. This condition traditionally has been treated with staged procedures. We report a case treated with a one stage procedure. A neuromusculocutaneous radial forearm free flap was used for the reconstruction of an achilles tendon and for covering the overlying large soft tissue defect caused by a gun shot injury. The defect on the Achilles tendon was 15 cm in length and soft tissue loss was 18 × 10 cm. The flap including flexor carpi radialis muscle tendon was applied over the Achilles tendon. A terminolateral arterial anostomosis was performed on the tibialis posterior artery. There was no complication except a mild superficial infection on the lateral side of the flap treated by antibiotherapy. A satisfactory functional result was obtained. Application of a free neuromusculocutaneous radial forearm composite flap is a good technique to cover achilles tendon and soft tissue defects and to restore the function as a one stage procedure.

    Giant cell tumor at the wrist: a review of 23 cases; [El bileginde dev hücreli tümör: yirmi üç olgunun incelenmesi.]
    (2006) Ozalp T.; Yercan H.; Okçu G.; Ozdemir O.; Coşkunol E.
    OBJECTIVES: We evaluated patients who underwent surgical treatment for giant cell tumor of the wrist with regard to recurrence rates, factors influencing tumor recurrence, complications, and postoperative functional and emotional status of the patients. METHODS: The study included 23 patients (6 males, 17 females; mean age 31.6 years; range 12 to 74 years) who were treated surgically for giant cell tumor of the wrist. Grading, assessment of surgical margins, and functional evaluation were performed according to the Enneking's criteria. The effects of tumor volume, soft tissue extension, and selected surgical therapy on recurrence were investigated. Joint movements and stability, postoperative pain, presence of deformity, muscle strength, limitations in functional activities, and patient satisfaction were evaluated. The mean follow-up period was 6.7 years. RESULTS: Of all the patients, 69% had stage 2 and 23% had stage 3 tumors. There was no significant correlation between tumor volume and recurrence (p=0.22). Recurrences were observed in three (33%) of nine patients with soft tissue extension and in four (28.6%) of 14 patients without soft tissue extension. Recurrence rates were 33.3% in those who were treated by curettage alone (n=3), 50% with curettage and grafting (n=6), 50% with curettage and bone cement (n=2), and 16% in those who underwent wide excision (n=12). CONCLUSION: The most important factor influencing recurrence rate in giant cell tumors is the extent of surgical resection. At least marginal resection must be considered in patients with stage 2 and 3 lesions especially in cases with soft tissue extension. Adjunctive therapy should be added if curettage is considered.

    Extensor indicis proprius transfers for extensor pollicis longus ruptures secondary to rheumatoid arthritis; [Romatoid artritte ekstansör pollisis longus kopmalari için ekstansör indisis proprius transferi.]
    (2007) Ozalp T.; Ozdemir O.; Coşkunol E.; Erkan S.; Calli I.H.
    OBJECTIVES: We evaluated the results of extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfers for EPL ruptures secondary to rheumatoid arthritis. METHODS: Twenty-four patients (7 males, 17 females; mean age 41 years; range 22 to 72 years) with rheumatoid arthritis underwent EIP to EPL transfer for 25 ruptures. The mean duration from rupture to surgery was 4.3 months (range 1.5 to 11 months). Functional assessment of the fingers was made using a specific EIP-EPL evaluation method developed by Lemmen et al. Pinch and grip strengths were measured. Range of motion of the metacarpophalangeal and interphalangeal joints of the thumb was compared with the normal side. Patient satisfaction was evaluated by a visual analog scale. The mean follow-up period was 6.2 years (range 4.7 to 7.9 years). RESULTS: Functional results were perfect in 14 fingers (56%), good in six fingers (24%), moderate in four fingers (16%), and poor in one finger (4%). The pinch and grip strengths were 86% and 92% of the uninvolved hand, respectively. The mean visual analog scale score was 74 (range 24 to 99). Compared to the uninvolved side, the range of motion of the thumb and index finger decreased by 23 degrees and 7 degrees , respectively, with a 9% loss of interphalangeal motion and a 17% loss of metacarpophalangeal motion in thumb extension. Independent extension of the index finger was possible in 21 hands. CONCLUSION: The results of EIP to EPL transfers are successful in ruptures secondary to rheumatoid arthritis.
