About this study

The treatment of scaphoid non union has no gold standard technique so in this study the investigators try to compare the arthroscopic and the open grafting techniques to determine the better technique to achieve union, time to union and the better functional outcomes including wrist range of motion and grip strength as a primary outcome and the secondary outcomes are the operative time, the complications and radiological correction of the hum-back deformity if present.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • scaphoid non-union cases
  • 16 years or older
  • males or females
  • independent from chronicity or non-union location and the investigators defined the non union as failure to reach scaphoid union up to 6 months

Exclusion criteria

.Revision scaphoid non-union cases.

  • Previously operated wrist for any other pathology
  • Avascular necrosis (AVN) confirmed by intraoperative inspection.
  • Scaphoid non-union advanced collapse (SNAC) stage 2 and higher.
  • Any associated wrist pathology that required separate treatment surgical approach.

Treatment and study plan

Arthroscopic grafting and k wires fixation

Procedure

Arthroscopic midrcarpal scaphoid non union debridment and iliac cancellous bone grafting with K wires fixation

open scaphoid grafting with K wires fixation

Procedure

open surgical volar or dorsal scaphoid non union site debridment and application of iliac bone graft and K wires fixation

Primary outcomes

  1. union rate

    Time frame: 6 months

    percentage of patients in each arm that achieve bony union

  2. time to union

    Time frame: 6 to 24 weeks

    the time that patient take to achieve bony union

  3. wrist flexion and extension

    Time frame: preoperative, at 6 months and at 24 months

    flexion and extension range of motion

  4. wrist radial and ulnar deviation

    Time frame: preoperative, at 6 months and at 24 months

    radial and ulnar deviation range of motion

  5. grip strength

    Time frame: preoperative , at 6 months and at 24 months

    the power of hand grip measured by dynamometer

  6. The disability of arm, shoulder and hand score (DASH score)

    Time frame: preoperative , at 6 months and at 24 months

    a questionnaire to assess upper limb function from 0 to 100 where the lower the score means better outcome

  7. The Mayo modified wrist score

    Time frame: preoperative, at 6 months and at 24 months

    A functional score that depends on the patients function and examination from 0 to 100 and the higher the score the higher the outcome

Secondary outcomes

  1. complications

    Time frame: 2 years post operative

  2. Degree of scaphoid hump back deformity correction

    Time frame: post operative after bony union up to 1 year

    Radiological parameter thorough scapholunate angle

  3. Operative time

    Time frame: intraoperative

    the duration of each operation
