Joint-sparing arthroscopic management of avascular necrosis of the capitate.

Avascular necrosis of the proximal pole of the capitate is an exceedingly rare pathology with few therapeutic solutions. The largest published series concerned a cohort of 6 cases over 10 years. The present case concerns our experience with avascular necrosis of the capitate in a 20-year-old woman. Due to her age and high functional demand, we opted for a minimally invasive solution using arthroscopy. We performed an X-shaped palmaris longus tendon interposition arthroplasty at the midcarpal joint between the capitate and the lunate. We here report 2 years' follow-up.

Repair of the dorsal capsuloligamentous scapholunate septum during arthroscopic resection of painful dorsal wrist ganglion cyst: Comparative analysis of two techniques.

We compared arthroscopic cyst resection (ACR) of dorsal ganglia of the wrist, either associated to reconstruction of the dorsal capsuloligamentous scapholunate septum (ACR-DCSS) in 66 cases in which the ganglia were painful on exertion, or isolated ACR in 15 pain-free cases. A single-center retrospective study analyzed data for the period April 2013 to May 2021. The main aim was to compare pre- and post-operative functional results (pain at rest (on a numerical rating scale: NRS), pain under effort (NRS), range of motion (°), grip strength (kg)) and recurrence rate between the two techniques. The study hypothesis was that DCSS repair improves recurrence of dorsal ganglion cyst and functional outcome. The ACR-DCSS group showed significant improvement in extension, pronation, supination, radial inclination, ulnar inclination, grip strength, pain at rest and pain on exertion. The ACR group showed significant improvement in pronation, ulnar inclination and pain on exertion. There was a significant difference in recurrence rate, in favor of ACR-DCSS. Recovery was also significantly better for the ACR-DCSS group in terms of extension, supination and pain at rest. Arthroscopic treatment of wrist ganglion cyst is a reliable, minimally invasive and reproducible technique that produces good results in terms of pain and recovery of range of motion, with significantly lower recurrence rate in case of DCSS repair. Level of evidence: Therapeutic III.

Management of a cornual ectopic pregnancy.

Cornual pregnancy is rare. Treatment involves expulsion of the pregnancy and hemostasis of the cornus if required by hemorrhagic rupture. Two techniques are proposed to achieve hemostasis of the uterine cornus, cornuotomy with suture, or corneal resection with salpingectomy, generally laparoscopically.
