The purpose of this study was to compare the clinical outcomes and wound complications in coccygectomy with or without subperiosteal resection. This retrospective study included 25 patients who underwent coccygectomy. Resection of all mobile coccygeal segments including the periosteum was performed in 11 patients (group 1) and resection was performed subperiostally sparing the periosteum in the remaining 14 patients (group 2). A visual analogue scale was used for pain assessment before and after the surgery both in sitting and standing positions. A questionnaire to evaluate subjective patient satisfaction was also used. The two groups were statistically similar in terms of age, sex, aetiology, duration of symptoms before surgery and follow-up time. Both surgical techniques resulted in a statistically similar clinical outcome. Overall, 84% of patients who underwent coccygectomy benefited from surgery. We observed four wound infections (two superficial and two deep) that caused delayed wound healing in group 1. The rate of infection in group 1 was statistically higher than in group 2. The results of this study suggest that periosteal preservation and closure are related to low risk of infection.

Immobilization of the shoulder in external rotation is an effective technique for prevention of recurrent dislocations in acute anterior shoulder dislocation and should be preferred to traditional splinting in internal rotation in clinical practice.

Tourniquet-induced IR period in routine arthroscopic knee surgery resulted in oxidative stress by increasing MDA, SOD, GSH-Px, TOS and decreasing TAC. NAC and IPC had protective effect on occurrence of oxidative stress resulting from IR period by preventing MDA, SOD, GSH-Px, TAC, and TOS changes in routine arthroscopic knee surgery.

Both O3-PC and HBO-PC reduced tissue lipid peroxidation, NOx levels, and iNOS staining scores in the experimental I/R model. Our data suggest that HBO-PC and O3-PC protect against oxidative/nitrosative stress induced by I/R in rat skeletal muscle.

PurposeThe purpose of this study was to evaluate the effects of alpha-tocopherol on distraction osteogenesis.Materials and methodsRight tibias of 30 New Zealand white rabbits were distracted at a rate of 0.5 mm/day for 20 days with a circular external fixator. Experimental group rabbits (n = 15) were administered i.m. 20 mg/kg/day alpha-tocopherol for 30 days. Radiographic examinations were performed at the 20th, 30th and 40th days. Bone scintigraphy was performed at the 5th and 20th days. Serum total antioxidant capacity (TAC) was measured at the 5th and 30th days. All animals were sacrificed and the right tibias of all animals were harvested for histopathologic examination at the 40th day.ResultsRadiologic scores were statistically similar at the 20th day. However, the experimental group demonstrated higher radiologic scores at the 30th and 40th days. A scintigraphic baseline study at the 5th day of the study showed statistically similar osteoblastic activities in both groups. However, at the 20th day, osteoblastic activity was significantly higher in the experimental group. Serum TAC values were also significantly higher in the experimental group at the 30th day. At necropsy, histopathologic examination revealed statistically significantly higher scores in the experimental group.ConclusionThe results of this study show that alpha-tocopherol has beneficial effects on new bone formation during distraction osteogenesis.

The purpose of this study is to compare the long-term clinical outcomes of patients who were treated with either hind foot reconstruction or amputation in complex hind foot injuries accompanied with bone and soft tissue loss due to land-mine explosions. Between 1994 and 2004, all patients with hind foot complex injuries due to land-mine explosion, who were operated in our clinic, were enrolled to the study. All patients were evaluated with Short-Form 36 (SF-36), Foot and Ankle Disability Index (FADI) and Body Image Quality of Life Inventory (BIQLI) after a mean of 15.1 ± 2.2 (range 9-19) years of follow-up. Demographic characteristics, number of operations, necessity of psychiatric treatment and all complications were compared between groups. There were a total of 42 patients [21 in reconstruction group (Gr I) and 21 in amputation group (Gr II)]. The mean age at the time of final follow-up was 38.4 ± 3.04 years in Gr I and 38.2 ± 4.24 years in Gr II (p = 0.732). The mean follow-up duration was 15.7 ± 2.07 years in Gr I and 14.57 ± 2.29 years in Gr II (p = 0.081). The number of operations was significantly higher in Gr I (8.66 ± 10.2 times vs. 4.42 ± 7.7 times, respectively, p = 0.001). The mean FADI score at the final follow-up was 64.3 ± 18.1 in Gr I. In amputation group, more patients needed psychotherapy due to major depression (12 patients vs. 4 patients, p = 0.012). Major complications in Gr I were musculocutaneous flap atrophy in calcaneal region (n = 8 patients), limited ankle motion (n = 11) and painful osteophytes on plantar region (n = 6). In Gr II, stump problems were dominating (pain and tenderness n = 10, ulcer n = 2, allergic skin lesions n = 7, painful neuroma n = 10, bony spur n = 5, paresthesia n = 1, excessive sweating n = 12). At the final visit, although SF-36 scores were similar between groups (p = 0.182), extremity reconstruction group had significantly higher BIQLI scores than the amputation group (p = 0.016). If the dorsalis pedis is intact and midfoot and forefoot is relatively protected, hind foot reconstruction should be attempted. Long-term outcomes of hind foot reconstruction are satisfactory with minor complications and better BIQLI.
