HOOK ASSISTED REDUCTION IN CEPHALOMEDULLARY NAILING WITHOUT TRACTION TABLE.

Introduction: Proximal femoral nailing for intertrochanteric femur fracture is sometimes a challenging procedure without a traction table, especially if complicated fracture pattern. We aimed to overcome this difficulty with the hook. Materials and Methods: A retrospective study of 60 patients. 28 of the patients reduction was necessitated with a hook (group 1). The other patients did not need to use this technique (group 2, n=32). The collo-diaphyseal angle, lag screw placement, and tip-apex distance were measured using radiographs. Results: There were statistically significant differences between the two groups regarding the Garden Alignment Index, postoperative collo-diaphyseal angle measurements, and tip-apex distance. The Garden Alignment Index was found as 163.92 degrees (dg.) In the frontal plane in group 1, and 154.78 dg in group 2, respectively. In group 1, the tip-apex distance was 16.05 cm, whereas it was 25.32 cm in group 2. The collo-diaphyseal angle was 133.1º in group 1, and 128.65º in group 2. Conclusions: The hook-assisted reduction is beneficial when operating without a traction table; however, it can also be a part of the surgeons' equipment even when operating on a traction table. When difficulties in obtaining an ideal anatomical reduction in displaced intertrochanteric femoral fractures, we suggest using the hook-assisted reduction technique.

Introdução: Frequentemente, a fixação do fêmur proximal para fratura intertrocantérica do fêmur sem uma mesa de tração é um procedimento desafiador, especialmente se o padrão da fratura for complicado. O objetivo foi superar essa dificuldade utilizando um gancho. Materiais e métodos: Trata-se de um estudo retrospectivo de 60 pacientes. Em 28 desses, a redução foi necessária com um gancho (grupo 1). Os outros pacientes não precisaram usar essa técnica (grupo 2, n=32). O ângulo colo-diafisário, a colocação do parafuso lag e a distância ponta-ápice foram medidos por meio de radiografias. Resultados: Houve diferenças estatisticamente significativas entre os dois grupos com relação ao Índice de Alinhamento de Garden, às medidas do ângulo colo-diafisário pós--operatório e à distância ponta-ápice. O índice de alinhamento de Garden foi de 163,92 graus (dg.) No plano frontal no grupo 1 e 154,78 dg no grupo 2, respectivamente. No grupo 1, a distância ponta-ápice foi de 16,05 cm, enquanto no grupo 2 foi de 25,32 cm. O ângulo colo-diafisário foi de 133,1 graus no grupo 1 e 128,65 graus no grupo 2. Conclusão: A redução assistida por gancho é benéfica quando se opera sem uma mesa de tração; no entanto, ela também pode fazer parte do equipamento do cirurgião mesmo quando se opera em uma mesa de tração. Quando houver dificuldades em obter uma redução anatômica ideal em fraturas femorais intertrocantéricas deslocadas, sugerimos o uso da técnica de redução assistida por gancho.

Mid-term follow-up results of gradual capitate lengthening for the treatment of stage IIIA Kienbock's disease.

PURPOSE: This study aimed to evaluate the mid-term radiological and clinical results of gradual lengthening of capitate for the treatment of stage IIIA Kienbock's disease. METHODS: We retrospectively reviewed nine patients (five females, four males) with Lichtman stage IIIA Kienbock's disease who underwent gradual capitate lengthening at our hospital. Their clinical (range of motion (ROM), grip strength, visual analogue scale (VAS) value for pain, and Mayo wrist score (MWS)) and radiological outcomes (in terms of progression of arthritis and carpal height ratio) at the last follow-up were compared to the preoperative values. RESULTS: The mean age of the nine patients was 30 years (range: 20-38 years). The mean follow-up period was 73.8 (60-83) months. The average grip strength increased from 14.3 kg preoperatively to 22.3 kg at the last follow-up. The mean MWS increased from 58.8 preoperatively to 79.4 postoperatively. The mean VAS values decreased from the preoperative values: from 1.9 to 0.36 at rest, from 3.75 to 1.6 during mild effort, and from 5.35 to 3 during severe effort. The average carpal height ratio changed from 0.38 preoperatively to 0.53 postoperatively. None of the patients had any arthritic changes in their wrists. CONCLUSION: Gradual lengthening of capitate offers satisfactory mid-term results for treating stage IIIA Kienbock's disease.

Acute correction of distal femoral deformities by retrograde femoral nail using preoperative planning.

PURPOSE: This study presents the technique and results of acute correction of distal femoral deformities using retrograde femoral nailing based on preoperative planning without using a fixator. METHODS: Twenty-eight patients (34 limbs: 22 left-sided, 12 right-sided, mean age = 36 years) undergoing distal femoral deformity correction with retrograde femoral nailing between 2013 and 2020 were examined retrospectively. The osteotomy line, block screw location and number were identified by detailed preoperative planning. Osteotomy was performed using the percutaneous multiple drill method, and the retrograde femoral nail was placed. RESULTS: The average follow-up period was 62.7 months (range: 13-84 months). Postoperatively, the mean mechanical axis deviation was corrected to 6.8 mm (range: 0-8 mm) and the mean mechanical lateral distal femoral angle to 87.42° (range: 84-90°). The Association for the Study an Application of the Method of Ilizarov (ASAMI) score was excellent for all patients. None of the patients had fracture, infection, implant failure, or non-union. CONCLUSION: Distal femoral deformities can be corrected acutely, without applying external fixators, with good preoperative planning and using the retrograde femoral nail. This technique is safe and effective, with a low complication rate.

Limb lengthening with one Precice nail over its capacity.

The Precice nail is used to treat limb length discrepancies and has a low complication rate and a high patient satisfaction rate. While the Precice nail can be used for lengthening, unlike other lengthening nails, it can also be used for shortening. We report a 37-year-old female patient with a 14 cm limb length discrepancy that was treated with a new surgical technique using the shortening feature of the Precice nail. Following maximum possible lengthening using the nail and without waiting for union on the osteotomy line, the distal interlocking screws were removed, and the nail was shortened by external remote control with the help of the fixator. The distal interlocking screws were then reattached to continue lengthening. This surgical technique can be used safely and satisfactorily in cases with more shortness as we can correct the extremity length discrepancy using only one nail.

Effect of cable cerclage on regional blood circulation in rabbits: a scintigraphic study.

PURPOSE: To evaluate changes in blood circulation of the femoral cortex in rabbits using scintigraphy before and after cable cerclage alone or combined with an intramedullary Kirschner wire. METHOD: Ten New Zealand rabbits were used. For the right femur, a 2-mm-thick cable was placed around the mid-diaphyseal region and squeezed with a 400-N force and locked with a clip. For the left femur, a 1.8-mm Kirschner wire was inserted retrogradely into the medullary canal, and a 2-mm-thick cable was applied using the same technique. The blood perfusion ratio of the region of interest (ROI) before and after surgery was evaluated using scintigraphy. RESULTS: For the right femurs, the mean ROI perfusion ratio decreased by 45% from 2.51 to 1.37 after intervention (p=0.001). For the left femurs, the mean ROI perfusion ratio decreased by 56% from 2.12 to 0.92 after intervention (p<0.001). The mean ROI perfusion ratio post-intervention was higher in the right than left femurs (p=0.017). CONCLUSION: Cable cerclage around the femoral cortex significantly decreased blood circulation in the area.

Early clinical and radiological results of minimally invasive total hip replacement.

INTRODUCTION: It is critical to achieve both proper component positioning and intact muscle balance if satisfactory results are to be attained after total hip replacement (THR). There have been fewer studies on minimally invasive (MI) THR than standard approaches. The objective of this paper is to present the early clinical and radiological results of posterolateral MI THR. MATERIALS AND METHODS: The retrospective analysis of the records of patients undergoing posterolateral MI THR surgery between 2011 and 2014 was the basis of this study. 73 hips of 68 patients were included in the study. The acetabular component and femoral stem positions were measured on plane X-rays. Data on preoperative and postoperative hemoglobin and hematocrit values, as well as transfusion amounts, were also studied. The clinical evaluations were carried out with Harris Hip Scores. RESULTS: The mean HHS at the 3rd postoperative month was 87.60 (±7.70). Of the 73 cases, 61 were within the Lewinnek safe zone. The mean PMFA was 88.12 (±7.63°), which is within the normal ranges. The mean postoperative hemoglobin value was 9.7 g/dl (±1.3) and the mean postoperative hematocrit value was 29.8% (±3.8). A nondisplaced proximal femoral fracture line was evident on the early postoperative X-ray of one patient. One patient experienced early dislocation caused by acetabular component malpositioning and an early acetabular cup revision was necessary. CONCLUSION: MI posterior approach for THR is a method in which the prosthetic components can be properly placed. Posterolateral MI approaches are safe when THR is performed, and afford satisfactory results.
