Fixation Methods of Basicervical Fractures

This prospective, randomized study included patients aged over 65 years with basicervical fracture of femur from January 2016 to January 2018. The permuted block randomization method was used to randomize participants into groups. The patients were allocated to one of two groups treated via cephalomedullary nail (CMN) or sliding hip screw (SHS). Functional and radiological evaluations was included the mobility score, Harris hip score, modified Barthel index, the Singh index, the tip-apex distance, and fracture settling.

About this study

Approval for this prospective randomized study was granted by the Local Ethics Review Board and all procedures were performed in accordance with the ethical standards of the Declaration of Helsinki (1964). Patients with a basicervical femur fracture were identified on admission to the Emergency Department of our tertiary hospital from January 2016 to January 2018. Patients with scheduled surgery who met the inclusion criteria and provided written informed consent were included in the study.

Patients were randomly allocated to a study group by permuted blocks of randomly mixed sizes and stratification according to the type of surgery (CMN or SHS). Randomization was applied using pre-prepared randomization cards, which were placed in opaque sealed envelopes and given to the surgeons to open just prior to surgery, and the designated procedure was then performed.

  • the ability to walk independently (with or without an aid) prior to fracture,
  • a fracture that had occurred less than one week prior to admission.

Exclusion criteria

  • history of ipsilateral femoral fracture,
  • a fracture due to malignancy,
  • limited life expectancy due to medical comorbidities,
  • any contraindication to surgery,

Treatment and study plan

cephalomedullary nail

Device

For patients in the cephalomedullary nail group, an incision was made in the gluteal area from the tip of the greater trochanter in proximal orientation. A guidewire was placed into the medullary canal from slightly medial to the exact tip of the greater trochanter. The entry point of the greater trochanter and proximal medullary canal were reamed. The cephalomedullary nail was then inserted and fixed to the femoral head with a double screw. The cephalomedullary nail was then locked distally using a guide arm. These cephalomedullary nails were not locked proximally to maintain dynamization and to allow compression across the basicervical fracture line.

sliding hip screw

Device

For patients in the sliding hip screw group, a lateral incision was made over the lateral proximal aspect of the femur. Under fluoroscopic guidance, the lag screw was placed centrally in the femoral head over the guidewire. A side plate with three holes was then attached to the hip screw.

Primary outcomes

  1. mobility score

    Time frame: 12 months

    Functional outcome was assessed by the mobility score of Parker and Palmer (Parker MJ, Palmer CR (1993) A new mobility score for predicting mortality after hip fracture. J Bone Joint Surg Br 75: 797-798), which uses a nine-point scale.

  2. Harris hip score

    Time frame: 12 months

    Hip function was rated with Harris Hip Score. The score has a maximum of 100 points (best possible function), covering pain (1 item, 0-44 points), function and activities (7 items, 0-47 points), and range of motion and absence of deformity (3 items, 0-9 points).

  3. modified Barthel index

    Time frame: 12 months

    Barthel Index (Mahoney FI, Barthel DW (1965) Functional evaluation: the Barthel Index. A simple index of independence useful in scoring improvement in the rehabilitation of the chronically ill. Md State Med J 13:61-65), which measures the level of functional independence for 10 activities of daily living and ranges from 0 to 100.

  4. the tip-apex distance

    Time frame: 12 months

    It uses a numerical value (the distance between tip of screw and subchondral area) to show placement of the screw in the head: higher values indicating higher likelihood of fixation failure by extrusion of the screw.

  5. fracture settling

    Time frame: 12 months

    It uses a numerical value to show placement of shortening of the fractured femoral neck in time
