Distal radius fractures AO type C : A clinical and radiographic investigation
- 2022

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The function of the hand is of substantial importance, and injuries have an impact on daily life. Distal radius fracture (DRF) is the most common fracture among adults. The annual incidence is 26 per 10,000 inhabitants, and the incidence is increasing because of an aging population. There has been a shift from conservative and other operative treatments, toward volar plate fixation to restore the anatomy and improve results. Operative treatment is often considered for displaced and unstable fractures. The optimal choice of treatment and fixation is still debated. The aim of this thesis was to study results after internal fixation of DRF AO type C.Study I (retrospective study, n=74) assessed outcomes after combined plating (CP) of DRFs AO type C, with 1-year follow-up. CP restored the anatomy and achieved a good functional outcome. The radiographic outcome did not correspond to the clinical or functional outcome.Study II (prospective study, n=97) assessed the prevalence of post-traumatic arthritis (PA) following CP of DRFs AO type C. CP yielded a good clinical outcome 7 years postoperatively and the prevalence of PA was low (29%). The presence of PA did not correlate with fracture group, radio-graphic, clinical, or functional outcome. Study III (randomized controlled trial, n=147) assessed the radiographic and clinical outcome following surgical treatment of DRFs AO type C, comparing volar plating (VP) with CP. Fixation with VP yieldedthe same radiographic and functional results as CP, but with a lower frequency of complications in the VP group.Study IV (prospective pilot study, n=10) assessed fragment migration with CTMA (CT-based micromotion analysis) after osteosynthesis with VP after DRF AO type C. The CTMA technique indicated that variable angle volar locking plate fixation can yield and maintain a stable reduction of the fracture fragments. CT volume registration could be a valuable tool in the detailed assessment of fracture fragment migration following VP fixation of DRFs.

- BACKGROUND: Volar locking plate fixation is the most common method of operative fixation of distal radius fractures (DRFs). For more complex cases, combined plating is an option for stabilizing intra-articular fragments. The prevalence of posttraumatic arthritis (PA) after an intra-articular DRF, and its relation to patient-reported outcome measures (PROMs), remains unclear. The purpose of this study was to study the prevalence of PA and its correlation to clinical outcome measures.METHODS: We evaluated 97 consecutive patients with intra-articular DRF, operated with combined plating, 7 years postoperatively. The primary outcome measure was the prevalence of radiographic PA. Secondary outcome measures included visual analog scale (VAS) pain score, hand grip strength, wrist range of motion (ROM), Patient-Rated Wrist Evaluation (PRWE) score, and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score. Radiographic examination was performed between 1 and 7 years postoperatively.RESULTS: The prevalence of PA was 29% at the 7-year follow-up. No correlation was found between PA and ROM, hand grip strength, PRWE, QuickDASH, VAS pain scores, or radiographic reduction. Median wrist ROM and grip strength were significantly inferior compared with the uninjured side. Hardware removal was performed in 51.5% of cases. There were 2 cases of tendon ruptures.CONCLUSIONS: Combined plating can yield a good clinical outcome 7 years postoperatively and a low prevalence of PA. The presence of PA did not correlate to clinical outcome measures or to the accuracy of anatomical reduction 1 year postoperatively. The frequency of tendon ruptures was acceptable, but the high frequency of hardware removal is a concern.

- PURPOSE: The optimal way to stabilize intra-articular distal radius fractures is unclear despite recent advances in surgical management. Volar plating is the most common treatment but may not be sufficient for more complex intra-articular AO type C fractures. The purpose of this randomized controlled study was to evaluate the radiographic and clinical outcomes following surgical treatment of AO type C distal radius fractures, comparing volar with combined plating.METHODS: In this study, 150 patients were randomized to volar locking plate (n = 75) or combined plating (n = 75) following a distal radius fracture AO type C. The 1-year follow-up included radiographic outcome (Batra score), visual analog scale pain score, hand grip strength, wrist range of motion, Patient-Rated Wrist Evaluation score, and Quick Disabilities of the Arm, Shoulder, and Hand score.RESULTS: Overall, 147 patients (median age 61 years) completed the 1-year follow-up (73 patients with volar plate and 74 with combined plating). No difference was found in radiographic outcome between the treatment groups. The volar plate group had significantly better Patient-Rated Wrist Evaluation scores, Quick Disabilities of the Arm, Shoulder, and Hand scores, hand grip strength, visual analog scale scores during activity, and flexion, extension, ulnar and radial deviation than the combined plate group. Hardware removal was performed in 10% in the volar plate group and in 31% in the combined plate group. There was no postoperative infection in the volar plate group but 3 cases in the combined plate group.CONCLUSIONS: In patients with complex AO type C intra-articular fractures, volar and combined plating yielded the same radiographic result. The differences in Patient-Rated Wrist Evaluation and Quick Disabilities of the Arm, Shoulder, and Hand scores between the groups did not reach the thresholds for minimal clinically important differences, suggesting similar clinical outcome. The combined plating group had a considerably higher frequency of hardware removal and postoperative infections.TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

Ten Year Follow-up After Total Wrist Arthroplasty
- 2017

Konferensbidrag (refereegranskat)abstract
- Hypothesis Total wrist arthroplasty (TWA) is an option in the management of wrist arthritis. The aim of the study was to evaluate the long-term results of TWA.Methods In this cohort study, we followed 56 cases that underwent TWA (Avanta, Biax, Universal 2 and Maestro) between 2005 and 2006 at a single-center. Data was collected preoperatively and 10 years postoperatively. Patient-related outcome measures, grip strength, range of motion (ROM), VAS pain scores were analyzed.Results VAS pain scores and patient-related measures were significantly improved at the 10-year follow-up. Jamar grip strength was also significantly improved. ROM remained largely unchanged, except for extension which improved significantly at the 10-year follow-up. Five of 56 TWAs were revised. Five patients died of unrelated causes and 10 were lost to follow-up.Summary Points This study shows good long-term results after TWA with a high level of patient satisfaction. The revision rate was acceptable.

- Purpose: To assess long-term implant survival in total wrist arthroplasty (TWA), comparing 4 different implants.Methods: In a prospective cohort of 124 patients, 136 TWAs were evaluated 5 years and 10 years after surgery. The TWAs were implanted between 2005 and 2009. The primary outcome was implant survival. Survival analysis was performed with revision and radiographic loosening as the final end point. Revision was defined as exchange of whole or parts of the prosthesis. Implant loosening was assessed using radiographic examination at the 5-year and 10-year follow-up. Secondary outcome measures included wrist range of motion, hand grip strength, visual analog scale (VAS) pain scores, and patient-related outcome measures, including Disabilities of the Arm, Shoulder, and Hand (DASH), Patient-Rated Wrist Evaluation (PRWE), and Canadian Occupational Performance Measure (COPM).Results: Total cumulative implant survival was 92% with revision as the primary end point. When including a nonrevised radiographic loose implant as a failure, total implant survival was 75%. Radiographic loosening differed significantly between the implants with a range in frequency from 0% to 37.5%. At the 10-year follow-up, assessing the nonrevised TWAs, range of motion was preserved compared with preoperative values. Significant improvement was recorded for hand grip strength, VAS pain scores, and patient-related outcome measures at the 10-year follow-up compared with preovperative values.Conclusions: High 10-year implant survival was found when defining the primary end point as revision of any cause. When including radiographic loosening of the implant in the survival analysis, implant survival was considerably lower. However, radiographic loosening does not seem to correlate with changes in secondary outcome measures, questioning the need for revision surgery in these cases.
