Gluteal Compartment Syndrome following an Iliac Bone Marrow Aspiration.

The compartment syndrome is a condition characterized by a raised hydraulic pressure within a closed and non expandable anatomical space. It leads to a vascular insufficiency that becomes critical once the vascular flow cannot return the fluids back to the venous system. This causes a potential irreversible damage of the contents of the compartment, especially within the muscle tissues. Gluteal compartment syndrome (GCS) secondary to hematomas is seldom reported. Here we present a case of a 51-year-old patient with history of a non-Hodgkin lymphoma who underwent a bone marrow aspiration from the posterior iliac crest that had excessive bleeding at the puncture zone. The patient complained of increasing pain, tenderness, and buttock swelling. Intraoperative pressure validation of the gluteal compartment was performed, and a GCS was diagnosed. The patient was treated with a gluteal region fasciotomy. The patient recovered from pain and swelling and was discharged shortly after from the hospital. We believe clotting and hematologic disorders are a primary risk factor in patients who require bone marrow aspirations or biopsies. It is important to improve awareness of GCS in order to achieve early diagnosis, avoid complications, and have a better prognosis.

Trivalent reconstruction for posterolateral and lateral knee instability.

Chronic posterolateral rotatory and lateral instability of the knee is approached from multiple anatomic and functional points of view. Traditional surgical techniques provide one-directional stabilization using autologous tendon transplantation and the split-tendon biceps procedure. Both of these resolve the lateral opening of the joint but do not secure the rest of the anatomic structures that are very important, such as the arcuate ligament and the capsule. This new approach to solving an old problem acts by tightening the fibular collateral ligament, arcuate ligament, the capsule (partially), and biceps tendon in 1 step by performing an oblique fibular-head osteotomy and pulling down these structures with good results. We report 2 cases in which this technique was used. The first was a 26-year-old man who hit the dashboard in an automobile accident and presented 1 week later with posterolateral instability associated with a tear of the posterior cruciate ligament. The second was a case of pure chronic lateral instability of the knee in a 32-year-old man who sustained a fall that caused a rupture of his lateral collateral ligament. This was repaired using a trivalent reconstruction at 3 months. Both patients successfully achieved good stability after reconstruction.
