Background Around 5 to 15% of all scaphoid fractures result in nonunion. Treatment of long-lasting scaphoid nonunion remains a challenge for the treating surgeon. Healing of scaphoid nonunion is essential for prevention of scaphoid nonunion advanced collapse and the subsequent predictable pattern of radiocarpal osteoarthritis. Purpose The purpose of this study was to investigate the feasibility of fixation of the scaphoid nonunion with a volar angular stable miniplate and cancellous bone grafting. We hypothesized that this technique could be successful, even in patients with previous surgery for nonunion and in patients with a long duration of nonunion. Patients and Methods A total of 21 patients enrolled in a single-center prospective cohort study. Healing of nonunion was assessed on multiplanar computed tomography scan of the wrist at a 3-month interval. Functional outcome was assessed by measuring grip strength, range of motion, and by means of the patient-rated wrist and hand evaluation (PRWHE) questionnaire. Results During follow-up, 19 out of 21 patients (90%) showed radiological healing of the nonunion. The range of motion did not improve significantly. Postoperative PRWHE scores decreased by 34 points. Healing occurred regardless of the length of time of the nonunion (range: 6–183 months) and regardless of previous surgery (38% of patients). Conclusion Volar angular stable miniplate fixation with autologous cancellous bone grafting is a successful technique for the treatment of chronic unstable scaphoid nonunion, even in patients with long-lasting nonunion and in patients who underwent previous surgery for a scaphoid fracture. Rotational interfragmentary stability might be an important determining factor for the successful treatment of unstable scaphoid nonunion. Level of Evidence Level IV.

Abstract Background Nonunion after open reduction and internal fixation (ORIF) of scaphoid fractures is reported in 5 to 30% of cases; however, predictors of nonunion are not clearly defined. Objective The purpose of this study is to determine fracture characteristics and surgical factors which may influence progression to nonunion after scaphoid fracture ORIF. Patients and Methods We performed a retrospective case–control study of scaphoid fractures treated by early ORIF between 2003 and 2017. Inclusion criteria were surgical fixation within 6 months from date of injury and postoperative CT with minimum clinical follow-up of 6 months to evaluate healing. Forty-eight patients were included in this study. Nonunion cases were matched by age, sex, and fracture location to patients who progressed to fracture union in the 1:2 ratio. Results This series of 48 patients matched 16 nonunion cases with 32 cases that progressed to union. Fracture location was proximal pole in 15% (7/48) and waist in 85% (41/48). Multivariate regression demonstrated that shorter length of time from injury to initial ORIF and smaller percent of proximal fracture fragment volume were significantly associated with scaphoid nonunion after ORIF (63 vs. 27 days and 34 vs. 40%, respectively). Receiver operating curve analysis revealed that fracture volume below 38% and time from injury to surgery greater than 31 days were associated with nonunion. Conclusion Increased likelihood for nonunion was found when the fracture was treated greater than 31 days from injury and when fracture volume was less than 38% of the entire scaphoid. Level of Evidence This is a Level III, therapeutic study.

We report the results of 28 patients with scaphoid nonunion treated with curettage and biconcave cancellous bone grafting from the distal radius using a volar approach and pin fixation. This study consisted of 28 patients (24 males and 4 females). The mean age at surgery was 28 years. The mean interval from injury to surgery was 22 months. The mean follow-up period was 20 months. By Russe classification, there were 6 distal third nonunions, 19 middle third nonunions and 3 proximal third nonunions. We reviewed final function and radiographic appearance. Bony union was achieved in all cases. Pins were removed at a mean of 7 weeks after surgery. Post-activity pain resolved in all cases. Mean wrist extension was 79° and mean flexion 77°. Mean grip strength was 35.8 kgf. The mean postoperative radio-lunate angle was 4.9° (-21–28.8) compared to -5.9° (-37.5–17.5) preoperatively. No complications were encountered. Our procedure is straightforward and not technically demanding. An STT arthrotomy is not necessary and the technique allows for concurrent correction of carpal instability. Bony union was achieved in all cases with no complications.

Aims Fixation of scaphoid nonunion with a volar locking plate and cancellous bone grafting has been shown to be a successful technique in small series. Few mid- or long-term follow-up studies have been reported. The aim of this study was to report the mid-term radiological and functional outcome of plate fixation for scaphoid nonunion. Methods Patients with a scaphoid nonunion were prospectively enrolled and treated with open reduction using a volar approach, debridement of the nonunion, and fixation using a locking plate and cancellous bone grafting, from the ipsilateral iliac crest. Follow-up included examination, functional assessment using the patient-rated wrist/hand evaluation (PRWHE), and multiplanar reformation CT scans at three-month intervals until union was confirmed. Results A total of 49 patients with a mean age of 31 years (16 to 74) and a mean duration of nonunion of 3.6 years (0.4 to 16) were included. Postoperatively, the nonunion healed in 47 patients (96%) as shown on CT scans. The mean time to union was 4.2 months (3 to 12). Due to impingement of the plate on the volar rim of the radius and functional limitation, the hardware was removed in 18 patients. At a median follow-up of 38 months in 34 patients, the mean active range of motion (ROM) improved significantly from 89° to 124° (SD 44°; p = 0.003). The mean grip strength improved significantly from 52% to 79% (SD 28%; p < 0.001) of the contralateral side. The mean PRWHE score improved significantly from 66 to 17 points (SD 25; p < 0.001). Conclusion Locking plate fixation supplemented with autologous cancellous bone grafting is a successful form of treatment for scaphoid nonunion. Functional outcomes improve with the passage of time, and mid-term results are excellent with a significant improvement in ROM, grip strength, and functional outcome as measured by the PRWHE.

We present the surgical outcomes of non-vascularized bone grafting taken from the iliac crest in 24 patients with scaphoid nonunion and avascular necrosis. The Fisk-Fernandez technique was used in 11 patients, and cancellous bone grafting was used in 13 patients. Bony union was achieved in 22 of the 24 patients. Non-vascularized iliac bone grafting can be used for the surgical management of scaphoid nonunion with avascular necrosis. Although revascularization of the proximal fragment after surgery was not evaluated, bony union was confirmed in nearly all patients. Level of evidence: IV

AbstractSymptomatic lunotriquetral coalition is very rare and need open surgery after failure of conservative treatment. We report a case of a symptomatic congenital lunotriquetral coalition type 1 according to the Minaar classification, at the left wrist of a 14-year-old boy. We performed an arthroscopic treatment with two compression screws and without cancellous bone grafting. Healing was obtained at 2 months postoperatively.

Scaphoid Fractures

We reviewed the outcomes of our dedicated clinic for suspected scaphoid fractures. The primary outcome measure was to test the reliability of accurately diagnosing an occult scaphoid fracture with a combination of anatomical snuff box, scaphoid tubercle, longitudinal compression tenderness, ulnar deviation and the pinch test. Cost savings of the new patient pathway was our secondary outcome measure. Between December 2016 and March 2020, 922 patients were recruited at a mean of 12 days post-injury. Sixty-five per cent ( n = 602) with a low clinical suspicion were discharged and 35% ( n = 320) with a high clinical suspicion had same day MRI scan. Fifty-eight scaphoid fractures were diagnosed and treated with no nonunions reported. Anatomical snuff box tenderness was the most sensitive test (90%). A combination of five tests better excluded an occult fracture (80% accuracy). The dedicated scaphoid clinic pathway resulted in 350 fewer follow-up visits and an overall saving of £59,666.
