Arthroscopic Scaphoid Grafting Versus Open Grafting in Scaphoid Non Union

December 25, 2025 updated by: Ain Shams University

Arthroscopic Scaphoid Bone Graft Combined With Percutaneous Fixation Versus Open Scaphoid Fixation With Non Vascularized Graft in Scaphoid Non-union

the investigators compare the arthroscopic grafting technique with the traditional open technique in th treatment of scaphoid non union as regards the union rate, time to union and functional outcomes to provide the best intervention to the patient

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
union rate
Time Frame: 6 months
percentage of patients in each arm that achieve bony union
6 months
time to union
Time Frame: 6 to 24 weeks
the time that patient take to achieve bony union
6 to 24 weeks
wrist flexion and extension
Time Frame: preoperative, at 6 months and at 24 months
flexion and extension range of motion
preoperative, at 6 months and at 24 months
wrist radial and ulnar deviation
Time Frame: preoperative, at 6 months and at 24 months
radial and ulnar deviation range of motion
preoperative, at 6 months and at 24 months
grip strength
Time Frame: preoperative , at 6 months and at 24 months
the power of hand grip measured by dynamometer
preoperative , at 6 months and at 24 months
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
preoperative , at 6 months and at 24 months
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
preoperative, at 6 months and at 24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
complications
Time Frame: 2 years post operative
2 years post operative
Degree of scaphoid hump back deformity correction
Time Frame: post operative after bony union up to 1 year
Radiological parameter thorough scapholunate angle
post operative after bony union up to 1 year
Operative time
Time Frame: intraoperative
the duration of each operation
intraoperative
