Proximal rectus femoris tendon avulsions are rare and occur mostly in male athletes. Currently, the standard of care for complete tendinous avulsions of the direct arm of the rectus femoris is nonoperative treatment. However, surgical repair may be considered in high-level athletes who have a high demand for repetitive hip flexion performed in an explosive manner or in patients in whom nonoperative treatment has failed. The purpose of this technical note is to describe the method for surgical repair of the proximal direct arm of the rectus femoris to its origin at the anterior inferior iliac spine using suture anchors.
Lack of necessary perfusion to the femoral head can lead to necrosis of the underlying bone (avascular necrosis) and result in femoral and acetabular surface changes in advanced stages. Numerous treatments have been reported in the literature, including nonoperative and surgical procedures. In addition to the standard core decompression, we describe the use of bone marrow aspirate to stimulate a healing response and bone grafting, allowing for immediate weight bearing postoperatively. The purpose of this article was to describe our method of core decompression augmented with bone marrow aspirate concentrate and bone grafting for the treatment of early avascular necrosis of the femoral head.
Purpose: The purpose of this study was to analyze the long-term results of humeral lengthening in achondroplastic patients and make suggestions on the most appropriate surgical technique to improve patient outcomes. Methods: Fifty-four humeral lengthening procedures performed in 27 achondroplastic patients were reviewed. Elongations were performed by means of callotasis with unilateral external fixation. Inclusion criteria were: achondroplastic patients under 17 years without prior arm operations and minimum follow-up of 36 months. Results: Fifty humeri in 25 patients (13 men and 12 women), aged between 9 and 17 years, met the inclusion criteria. Mean humeral lengthening was 8.82 cm (range: 5 to 10.5 cm), which represented an elongation of 54.80% (range: 46% to 63%) of the original length. The healing index was 0.91 months (range: 0.72 to 1.4 mo) per centimeter gained. Shoulder and elbow range of motion and stability were preserved in 47 limbs. Noncomplicated cases consistently experienced a significant functional improvement in the performance of activities of daily living such as putting on footwear and personal hygiene. Short-term complications included 11 pin-tract infections, 1 radial nerve neuropraxia, and 1 failure of the regenerated bone formation. None of these complications prevented from completion of treatment. Long-term complications included 2 cases of nonunion, 3 elbow flexion contractures, and 2 cases of psychological dissatisfaction, all of them in 4 patients. Factors associated with long-term complications were intraoperative fragment displacement and distal humeral osteotomy. No fractures of the regenerated bone were identified in the long term. Conclusions: Callotasis with unilateral external fixation is a reliable and well-tolerated procedure for humeral lengthening in achondroplastic patients, with an acceptable complication rate. Guided fixator placement and a proximal humeral osteotomy are strongly recommended technical tips as they may help prevent complications and improve outcomes. Level of Evidence: Level IV—case series.
Little is known about the origin and natural history of Blount disease. Treatment is always surgical and, given their complexity, should be preceded by a thorough analysis and planning regarding all deformities. Treatment principles are to correct the three-dimensional deformity and avoid recurrence. The choice of technique mainly depends on patient maturity and severity. Guided growth is a good choice for more immature patients with moderate deformities. Progressive correction using osteotomy or physeal distraction is indicated for patients with severe deformities and low remaining growth. The Taylor spatial frame is currently the most popular progressive correction device.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
