Complications After Intramedullary Fixation Treatment of Patients With Osteogenesis Imperfecta: Telescopic Versus Non-Telescopic Implants.

Introduction The treatment of musculoskeletal pathologies in osteogenesis imperfecta aims to provide the maximum possible function by preventing bone fractures and progressive deformities. Despite the development of implants used in the surgical treatment of osteogenesis imperfecta, there is no consensus on the most appropriate method for the correction of skeletal deformities. The aim of this study was to compare telescopic and non-telescopic implants in terms of postoperative complications. Methods  Twenty-three patients who were operated on for the diagnosis of osteogenesis imperfecta between 2005 and 2018 were retrospectively analyzed. Demographic data, follow-up times, and the total number of surgeries and complications were recorded. The operated bones were divided into two groups according to whether the intramedullary fixation material used was telescopic or not. Results  Twenty-one of 23 patients were included in the study due to the use of intramedullary fixation material in the operation. The mean age was 10.1 ± 2.9 years, and the mean follow-up period was 8.9 ± 3.5 years. Intramedullary fixation was applied to 43 long bones in 21 patients due to fracture or deformity. At least one complication was encountered in nine of 14 bones with telescopic implants and in 27 of 29 bones with non-telescopic implants. Major complications requiring surgical treatment were seen in seven bones of the telescopic implant group and 27 bones of the non-telescopic implant group. Conclusion The use of telescopic implants relatively reduces the complication rate and the need for repetitive surgery in patients with a diagnosis of osteogenesis imperfecta. However, the number of complications is still as high as with non-telescopic implants.

The Fate of Reoperation After Proximal Femur Fracture Surgery in Elderly Population.

INTRODUCTION: The overall complication rate after proximal femur fracture surgery is high. This study aims to define the reoperation reasons and outcomes of reoperations after proximal femur fracture surgery in elderly patients. METHODS: This retrospective cohort study included patients over 75 years of age who underwent surgery for an intertrochanteric femur fracture and femoral neck fracture between 2014 and 2021. The minimum follow-up was 12 months, or until the patient was deceased. The primary outcome measure was the success of reoperation with regard to fracture type and implant.  Results: A total of 89 patients required reoperation for an overall rate of 9.3% during follow-up. Infection was the leading reason for reoperation. Hemiarthroplasty (HA) for intertrochanteric fracture is associated with a high rate of infection compared with HA for femoral neck fracture. The success rate of reoperation due to postoperative infection was poor (46.3%) whereas the success rate for other implant-related complications was favorable (91.6%).  Conclusion: The risk of postoperative infection after HA is significantly higher for intertrochanteric femur fractures compared to neck fractures in the elderly population. The limited success after postoperative infection should be taken into consideration in decision-making.

Split Transfer of the Tibialis Anterior Tendon Combined With Calcaneocuboid Fusion vs Split Transfer of the Tibialis Anterior Tendon Alone to Treat Equinovarus Foot Deformity in Children With Cerebral Palsy.

BACKGROUND: The study aimed to compare the outcomes of combined calcaneocuboid arthrodesis and split anterior tibialis tendon transfer (SPLATT) procedure to isolated SPLATT surgery for the treatment of the spastic equinovarus deformity in children with cerebral palsy (CCP). METHODS: Forty-one ambulatory CCP with 56 equinovarus feet, with positive flexor withdrawal reflex test results, were studied. The average age was 9.1 ± 3.2 years (range 3-22). Patients were assigned into 2 groups based on the surgical procedures. Patients in group 1 underwent isolated SPLATT surgery, whereas patients in group 2 underwent the SPLATT procedure combined with calcaneocuboid arthrodesis. All feet were followed for at least 12 months after surgery. Patients were evaluated preoperatively and at the most recent follow-up visit. The hindfoot positions were assessed using Chang's criteria, the functional outcomes were assessed using Kling's criteria, and the ambulatory levels were assessed using the Gross Motor Function Classification System (GMFCS). RESULTS: Patients were followed for an average of 30.4 ± 14 (range 14-84) months. We found no difference between the groups in Chang's scoring (P = .550), better clinical outcomes (P = .034) according to the Kling criteria in SPLATT with calcaneocuboid fusion group, and postoperative GMFCS levels better in the SPLATT with calcaneocuboid fusion group (P = .025). CONCLUSION: In this retrospective comparative study to treat children with spastic equinovarus feet, patients who had the SPLATT procedure combined with calcaneocuboid arthrodesis generally resulted in better functional outcomes compared to isolated SPLATT surgery in spastic equinovarus foot. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Is immediate internal fixation safe in induced membrane technique?

OBJECTIVES: This study aimed to evaluate the treatment outcomes of patients treated with induced membrane technique (IMT) for the reconstruction of bone defects and to identify factors associated with the success and failure of the modified technique. PATIENTS AND METHODS: Between January 2016 and April 2021, a total of 23 adult patients (20 males, 3 females; median age: 39.9 years; range, 20 to 69 years) who underwent bone reconstruction using the IMT for established pseudoarthrosis and acute bone loss were retrospectively analyzed. Fracture type, the size and location of bone defect, the nature of the index injury, the type of fixation, the interval between stages of the operation, and any diagnosis of infection or other complications of the patients were assessed. RESULTS: The median bone union was achieved in 6.6 (range, 4 to 11) months. The median index of reconstruction was 19 (range, 10 to 30%). The main complications were recurrent infection in two cases and nonunion in one case. Massive graft resorption occurred in two cases. CONCLUSION: Immediate internal fixation is a reliable and effective method in the treatment of complex bone defects. A large volume of autograft is required for the reconstruction of long defects, which presents as a limiting factor, particularly in patients undergoing previous surgical interventions.

Management of tibial non-unions with Masquelet technique after failed previous treatment options for Grade III open fractures.

BACKGROUND: Non-union is a serious complication of open tibial fractures. This case series investigates the efficiency of the induced membrane technique in patients with tibial exposed non-union. METHODS: Eleven consecutive male patients with non-union after an open tibia fracture were enrolled into the study. The mean age of the patients was 40.7 (25-63). Induced membrane technique described by Masquelet was performed. Operative treatment with a temporary polymethylmethacrylate cement spacer to induce membrane formation followed by spacer removal and bone grafting at 7.35 (6-10) weeks were performed. Time to union, time to full weight-bearing, and any complications were evaluated. RESULTS: The average follow-up period of patients was 24.6 (13-40) months after the second stage. The mean length of bone defects after radical debridement was 51 mm (25-98). Fracture healing was observed in 9 patients (81%). The mean time needed to obtain bony union healing was 8.1 (8-12) weeks after second stage of surgery. Patients were allowed to full weight bearing as tolerated at 12 weeks. Two patients were failed to obtain bony union and infection control. One patient had below knee amputation due to persistant infection. Vascularized bone graft was performed for other patient due to the inability to obtain bone union. CONCLUSION: The induced membrane technique is a reliable and reproducible treatment modality for tibial non-unions after failed open fracture treatment. However, it is unpredictable to obtain bony union and control of infection in initial infected non-unions with a large bone defect.

Is It Necessary To Add Soft Tissue Injury to the Classification in Tibial Plateau Fracture Management?

Background A gold standard classification for the treatment of tibial plateau fractures with soft tissue injury has not been established yet.This study aimed to evaluate the usability of a novel modified classification that can provide preoperative information to the surgeon about soft tissue injuries in tibial plateau fractures. Methodology A total of 36 patients with tibial plateau fractures were included in the study. Patients' age, gender, and affected sides were recorded. Injuries to the medial meniscus, lateral meniscus, anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament, and lateral collateral ligament were examined with preoperative magnetic resonance imaging. Soft tissue injuries were arranged according to the novel modified classification based on the Schatzker classification. Results The mean age of the study participants was 45 (19-76) years; 72% of the patients were men and 28% were women. Moreover, 44% and 56% of the patients had broken the right and left tibial plateaus, respectively. At least one soft tissue injury was detected in 29 (81%) patients. In 14 (39%) patients, two or more soft tissue injuries were observed. All patients were arranged according to the novel modified classification regarding ligament and meniscus injuries. Conclusions With this novel modified classification system, we think that having better information about the preoperative condition of the soft tissue injuries can change the surgical strategy in patients with tibial plateau fractures.

Is open reduction necessary for pediatric T-condylar fractures of the humerus?

The aim of this study was to investigate the outcomes of closed reduction and percutaneous pinning (Kirschner wire fixation) as a less invasive method for the treatment of pediatric T-condylar fractures of the humerus compared with open reduction and pinning. Among pediatric patients who were diagnosed with T-condylar fractures of the humerus between 2010 and 2017, those who underwent closed reduction and percutaneous pinning were retrospectively evaluated. The surgical technique used was to restore joint alignment through closed reduction and then to insert a pin parallel to the joint surface to stabilize the intercondylar fracture. Then, the supracondylar fracture was fixed with crossed pins. At 1-year follow-up, rotation, angulation, and joint range of motion were evaluated. Patient satisfaction was assessed subjectively using the visual analogue scale. Early and late postoperative Baumann angles were measured. All patients were male, and the mean age was 10.8 ± 4.6 years. The mean follow-up duration was 16.5 ± 7.2 months, and the mean union duration was 7.4 ± 2.3 weeks. None of the patients had any rotational deformities, but two had 5° of varus, one had 5° of valgus, two had a flexion contracture of 10°, and one had a flexion contracture of 40°. The only complication observed was a pin-tract infection, which developed in one patient. The mean visual analogue scale score was 9.25 ± 1. In pediatric patients with T-condylar humerus fractures, closed reduction and percutaneous pinning may be a good alternative to open reduction and pinning, because it is less invasive and does not cause additional complications.

Do Patients With Acute Isolated Pubic Ramus Fractures Have To Be Hospitalized?

A total of 129 patients were included in the study. Haemoglobin levels on admission and at 24 hours were evaluated. Radiographs and computed tomography of the pelvis were also evaluated. The patients were divided into subgroups, according to the accompanying occult posterior pelvic injuries, whether they received anticoagulant-antiaggregant treatment, the number of pubic ramus fractures (single or multiple), the level of energy (low or high) and the zone(s) of the fracture(s). The mean haemoglobin decrease was 1.21 g/dL. Forty-six of the patients were under anticoagulant or antiaggregant treatment. Fifty-one of the fractures occurred due to low energy trauma. Posterior ring injuries were observed in 75 of the patients. Haemoglobin level decreases were statistically significant in injuries with high energy trauma aetiology, in patients using antiaggregant or anticoagulant and in fractures of the lateral half of the superior pubic ramus. It is important to follow all pubic ramus fractures closely because, even in low energy trauma, haemoglobin levels could decrease significantly. We recommend hospitalization to monitor this group of patients.

How are outcomes affected by performing a one-stage combined procedure simultaneously in bilateral developmental hip dysplasia?

PURPOSE: The aim of this study was to compare the outcomes of one-stage combined surgical treatment in children of unilateral and bilateral developmental hip dysplasia diagnosed after walking age. METHODS: We reviewed 24 patients who underwent one-stage combined surgery for DDH diagnosed after walking age. Group I consisted of 12 patients with bilateral disease who underwent bilateral operation at one operative setting. Group II consisted of 12 patients with unilateral disease. Pre-operatively the hips were classified according to Tönnis classification. Acetabular dysplasia was evaluated by measuring acetabular index (AI) angles pre-operatively. The acetabular improvements with time regarding AI was noted immediately postoperatively, every six months, and at the final follow-up examination. RESULTS: Mean follow up of the bilateral group I and group II were 54.8 months (range 20-84 months) and 52.6 months (24-80), respectively. There were no statistically significant differences between immediate postoperative and final follow up acetabular index improvement rates in both groups. Also there was no significant difference when both hips were compared in group I. The clinical final outcome of both groups and within group I was similar. CONCLUSIONS: Simultaneous combined surgery is a challenging but worthwhile procedure for late diagnosed patients with bilateral DDH. The short-mid term outcomes of the procedure are encouraging.
