All-Arthroscopic Reconstruction of Severe Chronic Acromioclavicular Joint Dislocations.

Chronic exertional compartment syndrome is a well-described potential cause of leg pain in high-level athletes and soldiers. Surgical treatment of chronic exertional compartment syndrome usually involves fasciotomy, with a reported rate of complications of up to 16%, including failure of complete compartmental release and delayed return to normal daily activity, which can take up to 6 to 12 weeks. The use of a minimally invasive approach under ultrasound guidance seems to improve clinical outcomes in young active patients. We recommend the following steps for effective execution of ultrasound-guided percutaneous fasciotomy: (1) location of the compartmental fascia and identification of the superficial peroneal nerve, (2) skin incision, (3) insertion of a hook under the compartmental fascia, and (4) sectioning of the fascia.

Ultrasound-Guided Percutaneous Fasciotomies for Patients With Chronic Exertional Compartment Syndrome.

The Flexor Hallucis Longus (FHL) is a muscle that can be subject to multiple conflicts. The most common conflict is due to inflammation of the tendon at the retrotalar pulley. The constraints exerted on the FHL are responsible for a pathology called functional Hallux Limitus. The purpose of this anatomical study is to describe morphologic finding about retrotalar pulley, which may account the impingement between FHL and the hindfoot. Using a retrospective approach at a single center, a detailed analysis was conducted on a cohort of 350 patients. Precise measurements were taken to document the angles, areas, and distances that define the relationship between the Flexor Hallucis Longus (FHL) tendon and its surrounding anatomical structures. The angle between the retrotalar pulley and the sustentaculum tali exhibited a range of 124 to 170 degrees in profile and 113.3 to 178 degrees in frontal view. The dimensions of the retrotalar pulley varied from 1.1 to 54 mm², while the posterolateral and posteromedial tubercles displayed dimensions ranging from 3.4 to 77.9 mm² and 2.6 to 35.2 mm², respectively. Distances between posterior tubercles further underscored the anatomical diversity, ranging from 4.3 to 17 cm proximally and 10.5 to 18.4 cm distally. In unraveling the morphological complexities surrounding FHL impingement, this study provides valuable insights into the biomechanical intricacies of the foot. These findings not only deepen our understanding of musculoskeletal anatomy but also pave the way for future investigations into the dynamic interplay between structure and function in the lower extremities.

Iliopsoas tendon impingement after total hip replacement has been reported with an incidence of up to 8.3%. Iliopsoas tendon impingement has also been observed in young active patients engaged in extreme sports. In such cases, surgical iliopsoas tendon release or tenotomy may be considered to improve anterior hip pain and function. Currently, iliopsoas tenotomy is performed either in an open manner or arthroscopically. This article describes a surgical technique using percutaneous ultrasound-guided iliopsoas tenotomy in cadaveric models. We perform the release at the acetabulum because it is safe and provides good sonographic visualization. This study describes the effectiveness of percutaneous iliopsoas tendon tenotomy under ultrasound guidance. However, clinical studies are warranted to confirm these findings. This minimally invasive procedure opens opportunities for clinical applications, comparing outcomes with those of standard approaches and conducting cost analyses. It may offer a cost-effective outpatient clinic option with local anesthesia, avoiding operating room expenses.

Ultrasound-Guided Iliopsoas Tenotomy for Iliopsoas Tendon Impingement: Surgical Technique in Cadaveric Models.

 Soft-tissue defects surrounding the big toe can be a challenging problem for reconstructive surgeons. The first dorsal metatarsal artery (FDMtA) arises from the dorsalis pedis artery, which itself arises in front of the ankle joint from the anterior tibial artery. This study aimed to characterize the FDMtA cutaneous perforators (FDMtAPs) and evaluate the potential of a local pedicled perforator flap to cover a hallux soft-tissue defect.  Nine feet from fresh cadavers were dissected to describe the FDMtAP anatomy. For each artery, we recorded the origin's position from the FDMtA, the proximal and distal diameters, and the artery's course, length, number, and type. We described the FDMtA perforator flap harvest and its application through a clinical case.  A mean of 3.67 ± 1.23 FDMtAPs were found from the nine dissected feet, with at least 2 perforators per foot. Around 88% were located between 0 and 4 cm along the axis at their origin from the FDMtA, with an area of around 8 cm and a mean of 2.35 ± 0.36 cm long. The proximal diameter had a mean of 0.178 ± 0.037 mm and 0.110 ± 0.008 mm at the distal diameter. A pedicled flap was readily feasible for all dissections. The case described had satisfactory healing, correct functional, and aesthetic recovery at two months.  The first dorsal metatarsal artery perforator flap seems to be a reliable and valuable solution for the hallux soft-tissue reconstruction, notably after the excision of acral melanoma.
