Study Details

Brief summary:

The purpose of this study is to investigate whether treatment of scaphoid non-unions with a vascularized bone grafts improves patient reported pain and disability compared to treatment with a non-vascularized bone graft. Secondary objectives are to examine if there is any difference in the overall rate and time to union, range of motion, grip strength, or complication rates between the two groups.

In addition, this is the first prospective randomized study to directly compare the two techniques. This is also the first study to use standardized methods of assessing union (based on computerized tomography), standardized methods of collecting objective patient data, and utilizing validated patient questionnaires to assess pain and disability.

Eligibility Criteria

Sex: All

Age: 18 - 70+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • The primary inclusion criterion is any scaphoid waist or proximal pole non-union in a patient receiving a recommendation for operative treatment. Non-union is defined as <10% bony union across the fracture site on sagittal computerized tomography (CT) after at least 16 weeks of appropriate non-operative treatment or morphologic features on plain x-ray and CT (resorption and sclerosis at the fracture site, significant cyst formation) confirming non-union.

Exclusion Criteria:

  • radiologic evidence of significant scaphoid non-union advanced collapse (SNAC) wrist arthritis
  • fragmentation of the proximal pole

Interventions and Outcome Measures

Arms

active comparator: Vascularized Bone Graft

Patients randomized to a vascularized bone graft will undergo a 1, 2-ICRSA vascularized bone graft based upon the 1,2 supra-retinacular vessels as described by Zaidemberg . (9. Zaidemberg C, Siebert JW, Angrigiani C. A new vascularized bone graft for scaphoid nonunion. J Hand Surg. 1991; 16A: 474-478.)

active comparator: Non-Vascularized Bone Graft

Patients randomized to the non-vascularized group will undergo trapezoidal bone grafting from the iliac crest as described by Fernandez . (10. Fernandez DL. A technique for anterior wedge-shaped grafts for scaphoid nonunions with carpal instability. J Hand Surg \[Am\]. 1984 Sep;9(5):733-7.)
