Hip arthroscopy technique and indications.

The recent advances in hip arthroscopy have made it a useful minimally invasive approach to the diagnosis and treatment of intra-articular hip pathology. It offers the benefits of being an outpatient procedure with short rehabilitation and few reported complications and does not hinder opportunities for future surgical interventions. The lateral approach has been widely accepted, and technical details are discussed. Patients typically present with mechanical symptoms and persistent pain resistant to a reasonable trial of conservative treatment and are without significant joint space narrowing. Indications include debridement of labral lesions and loose bodies as well as treatment of impingement syndrome and avascular necrosis. Arthroscopy has also proven a useful tool in evaluation components in symptomatic patients after hip arthroplasty and in the treatment of native and replacement joint infections.

External beam radiation helps prevent heterotopic bone formation in patients with a history of heterotopic ossification.

The aim of this study was to determine if radiation prevents heterotopic ossification (HO) in HO-forming patients after total hip arthroplasty (THA) or HO excision alone. Patients with HO in the ipsilateral hip (63 treated with THA revision and 25 treated with HO excision alone) and HO in the contralateral hip (36 treated with primary THA) were termed HO-forming patients. They underwent radiation to prevent HO. After excluding patients with inadequate follow-up, 84 patients were studied to determine if radiation prevents significant HO (Brooker Grade 3-4). For patients with ipsilateral hip HO, 12.3% developed significant HO. In patients with contralateral hip HO, 10.5% developed significant HO after THA. Sixty percent who received 6 Gy in 3 fractions after excision of ipsilateral HO developed significant HO, which was higher than for all dose-fractionation schemes combined (P = .01). In contrast, patients who received 7 Gy in 1 fraction developed significant HO 13.8% of the time, which was equivalent to all dose-fractionation schemes combined (P = not significant). Radiation prevents HO in HO-forming patients.

Hip arthroscopy: surgical approach, positioning, and distraction.

The hip is the most deeply recessed joint in the body making it difficult to access arthroscopically. However, for the patient with a symptomatic loose body or labral tear open techniques are less advantageous. It is for this reason that, however difficult, minimally-invasive approaches to the hip have been developed. Meticulous attention to proper positioning and portal placement is paramount for safe and successful arthroscopy of the hip. The current authors will review the seminal features of positioning and minimally-invasive surgical approaches to the hip.

The role of hip arthroscopy in the treatment of synovial disorders and loose bodies.

Arthroscopic surgery of the hip is an evolving procedure that can facilitate the diagnosis and treatment of synovial-based disease. Radiographic studies have not reproducibly identified many of the synovial conditions that can affect the hip, and arthroscopy has provided a means to improved diagnostic accuracy and the ability to treat certain conditions. Arthroscopic intervention has been reported in synovial chondromatosis and osteochondromatosis, pigmented villonodular synovitis, inflammatory arthropathies including rheumatoid arthritis, and acute septic arthritis. Patients with other conditions that result in acute and chronic synovitis within the hip such as hemosiderotic synovitis secondary to hemophilia and chondrocalcinosis also may benefit from arthroscopic intervention. These synovial and intraarticular abnormalities have been associated with accelerated joint degeneration, and although the pathologic mechanisms have not been delineated clearly, the clinical description has been advanced using hip arthroscopy. Increased awareness of the association between synovial abnormalities and degeneration has resulted from arthroscopy applied to the hip in early stages of disease and early in the course of symptomatic dysfunction. The indications and treatment capabilities will continue to expand with additional understanding of early hip disease, improvements in equipment, and as outcome studies reveal that the patient benefits from the procedure.
