Conditions

31-A2 intertrochanteric fractures: fracture extends over two or more levels of medial cortex Injury, Occupational Diseases, Poisoning 31-A2 intertrochanteric fractures

Interventions

This is a retrospective study. All patients underwent closed reduction and internal fixation (CRIF) with the intramedullary nail. The CT data of 43 patients with 31-A2 intertrochanteric fractures who

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: 1. Acute unilateral closed fractures 2. At least 3 consecutive (preoperative, within one-week postoperative, 3-months follow-up) CT examinations in addition to the X-ray radiographs 3. Patients aged 60 years and older 4. Follow-up periods of more than six months postoperatively 5. Nail shafts with the static distal locking

Exclusion criteria

Exclusion criteria: 1. Pathological fractures such as carcinomas, metastases of the bone, primary malignant or benign tumors, and metabolic disorders 2. Mental disorders 3. Walking with assistive devices before the fractures 4. Fractures with associated neurovascular injuries 5. Pre-existing osteoarthritis or previous surgeries to the affected hip joints

Design outcomes

Primary

Measure	Time frame
Radiographic parameters including Mean loss of the femoral neck-shaft angle (FNSA), sliding distance of cephal nail, change of Tip-cortex distance (TCD), change of Femoral head height (FHH) are measured using the Mimics software (Materialise, Leuven, Belgium) at three month follow up.	—

Secondary

Measure	Time frame
1. Hip function of patient was measured using Harris hip score (HHS) at the final follow-up 2. Time taken to rise from a sitting position and walk for 20 m is measured using timed “Up & Go” (TUG) test at the final follow-up 3. Functional level was also measured using the Parker-Palmer mobility score at the final follow-up 4. We defined loss of reduction as the loss of NSA greater than 10°, which is measured using the CT or radiographs 5. Cut-out is measured using the radiographs during the follow-up 6. Excessive sliding was defined as sliding distance = 10 mm, which is measured using the CT or radiographs 7. Implant breakage is measured using the CT or radiographs during the follow-up	—
