METHOD FOR OSTEOSYNTHESIS OF FEMUR NECK Russian patent published in 1997 - IPC

FIELD: medicine; traumatology; orthopedics; treatment of femur neck fractures. SUBSTANCE: patient lying in supine position is subjected to peridural or general anesthesia. External lateral incision 6-9 cm long is plactised to provide access into subtrochanterian region and bore is drilled in cortical layer of bone at point of would-be insertion of three-flange nail. Second incision 6-9 cm long practised on anterior surface of hip joint provides access to joint capsule. Incision is started from spina anterior inferior and is directed longitudinally downwards. Fascia femoris is dissected to penetrate into region between tailor's muscle and broad fascia tensor. Muscular- tendinous portion of musculus rectus and musculus iliopsoas are drawn towards inside. In transcervical and subcapital fracture cases, hip joint capsule is dissected along femur neck axis, whereas in basal fracture cases dissection is practised at neck base. Under surgeon's visual control reposition is practised, followed by introducing guide wire rod from incision, via subtrochanterian region, into femur neck and head. Wire rod is used to drive nail into femur head. In basal fracture cases, nail can be driven without preliminary insertion of guide wire rod. There exist no contraindications against using proposed method which is atraumatic and rapid to perform. Reposition of broken femur neck fragments is accurate and needs no preliminary X-raying. Apart from three- flange nail, other currently used fixatives for osteosynthesis can be inserted (Seppo fixative, rods with differently pitched threads, etc.). EFFECT: shorter rehabilitation time.
