Wrist Arthrodesis with Vascularized Fibular Graft after Failed Allograft Replacement for Giant-Cell Tumor Resection

Giant-cell tumor (GCT) is locally aggressive bone neoplasm, with an unpredictable pattern of biological aggressiveness. The optimal treatment had to achieve a negligible local recurrence rate while maximizing musculoskeletal function. Numerous options for reconstruction are available, but in the literature there is a lack of salvage surgery data. We present a case of a 67-year-old woman who underwent complete wrist arthrodesis with vascularized fibular graft as salvage procedure for allograft necrosis, after excision of a distal radius GCT. The patient did not complain of any impairment in daily use, and the functional score was 22 points (73%) at latest follow-up of 14 months. Despite joint salvage remains the most favorable treatment with regard to functional outcome for aggressive tumors of the distal radius, vascularized fibular grafts is a valuable alternative especially in salvage procedures, where the use of another allograft could lead to higher complications rate.

Does Proximal Row Carpectomy Improve Union in Wrist Arthrodesis? A Retrospective Cohort Study

Background Some surgeons advocate for concomitant proximal row carpectomy (PRC) with total wrist arthrodesis (TWA), though there are limited data to support or oppose this view. Questions/Purposes Does concomitant PRC improve rates of union, revision, hardware loosening, hardware failure, and hardware removal in TWA? Patients and Methods A retrospective cohort study of patients who underwent TWA with and without concomitant PRC between January 2008 and December 2018 was undertaken. Patients were included if they underwent TWA using a dorsal spanning plate. Patients were excluded if they underwent partial wrist arthrodesis, revision TWA, or TWA with nondorsal spanning plate fixation. Results A total of 183 wrists in 180 patients were included in the study, 96 (52.5%) in the TWA only and 87 (47.5%) in the TWA + PRC groups. Median clinical and radiographic follow-up was 18.0 months (3.0–133.0 months) in the TWA + PRC group and 18.5 months (2.0–126.0 months) in the TWA only group (p = 0.907). No difference in nonunion (TWA + PRC: 13/87 [14.9%], TWA only: 18/96 [18.8%], odds ratio: 0.76, p = 0.494), revision (TWA + PRC: 5/87 [5.75%], TWA only: 8/96 [8.33%], hazard ratio [HR]: 0.73, p = 0.586), loosening (TWA + PRC: 4/87 [4.60%], TWA only: 6/96 [6.25%], HR: 0.74, p = 0.646), failure (TWA + PRC: 5/87 [5.75%], TWA only: 4/96 [4.17%], HR: 1.55, p = 0.530), and removal (TWA + PRC: 12/87 [13.8%], TWA only: 16/96 [16.7%], HR: 0.84, p = 0.634) were identified. Conclusion Concomitant PRC might not improve rates of union or diminish complications in patient undergoing TWA. The role of PRC and the rationale for its use in TWA need to be individualized and discussed with patients prior to surgery. Level of Evidence This is a Level IV, therapeutic study.

Comparative outcomes of total wrist arthrodesis for salvage of failed total wrist arthroplasty and primary wrist arthrodesis

A retrospective study compared outcomes of total wrist arthrodesis as a salvage for total wrist arthroplasty versus primary total wrist arthrodesis. Seventy-one wrists were reviewed after a minimum follow-up of 12 months. Thirty-two wrists with failed total wrist arthroplasty were converted to a wrist arthrodesis and 39 wrists received a primary wrist arthrodesis. Seven converted wrist arthrodeses and five primary arthrodeses failed to fuse. Mean patient-rated wrist and hand evaluation scores and work-related questionnaire for upper extremity disorders scores were 43 and 39 for converted total wrist arthrodesis and 38 and 33 for the primary total wrist arthrodesis. Overall, there were 25 complications in 15 patients in the converted wrist arthrodesis group and 21 complications in 16 patients after a primary wrist arthrodesis. The results between the two groups were slightly in favour of patients with a primary wrist arthrodesis. Therefore, we conclude that the timing, primary or conversion, of total wrist arthrodesis could influence patient outcomes. Level of evidence: III

Surgical Solution for Total Carpectomy due to Destructive Wrist Pan-Osteomyelitis Using a Free Femoral Condyle Osteocutaneous Flap for Wrist Arthrodesis

Osteomyelitis of the hand is rare, even more so in the carpal bones. Patients with rheumatoid arthritis (RA) have a higher infection rate overall, and up to a 14-fold increase in the incidence of septic arthritis of the hand. The destruction of immunologic barriers, such as cartilage and joint capsules, as well as the use of immunosuppressive medications will have an impact on the higher incidence of articular infections and osteomyelitis in these patients. Infection in these cases is often overlooked because of the similarity of presentation to an acute event of RA. When osteomyelitis is present, rapid and aggressive treatment should be given. Surgical debridement, lavage, and excision of necrotic bone is the best choice, followed by cemented antibiotic impregnated spacer to resolve the acute scenario. Vascularized bone grafts (VBG) can then be used for a definitive solution, as these have great biologic properties that increase the possibility of a good outcome. We hereby present a report of a wrist arthrodesis, using a free medial femoral condyle VBG for the treatment of destructive osteomyelitis of the carpal bones in a female patient with RA.

Total wrist arthrodesis with and without arthrodesis of the carpoMetacarpal joint (WAWWAM): study protocol

Background It is controversial whether or not the carpometacarpal joint (CMCJ) should be included in total wrist arthrodesis (TWA). Complications commonly occur at this site and studies examining its inclusion and exclusion are conflicting. A randomised clinical trial comparing wrist arthrodesis with CMCJ arthrodesis and spanning plate to wrist arthrodesis with CMCJ preservation and non-CMCJ spanning plate has not been performed. Method A single centre randomised clinical trial including 120 adults with end-stage isolated wrist arthritis will be performed to compare TWA with and without the CMCJ included in the arthrodesis. The primary outcome is complications in the first post-operative year. Secondary outcomes are Disabilities of the Arm, Shoulder and Hand (DASH) score, Patient Rated Wrist Evaluation (PRWE) and grip strength measured at 1, 2 and 5 years. Late complications, return to work and satisfaction will also be recorded. Discussion It is unknown whether the CMCJ should be included in TWA. This trial will contribute to an improved understanding of optimal management of the CMCJ in total wrist arthrodesis. Trial registration This trial was prospectively registered with the Australia New Zealand Clinical Trials Registry with identifying number ACTRN12621000169842 on the 16th February 2021. WHO: U1111–12626523. ANZCTR: ACTRN12621000169842

DISTAL RADIUS RECONSTRUCTION USING FIBULAR GRAFTS

Giant cell tumor (GCT) of bone is a locally aggressive tumor of bone. GCT involving the distal radius poses certain unique challenges in management. The resection of the tumor will almost always end up requiring a reconstructive procedure of the joint, for which several different methods of reconstruction have been explored. We present a case of a 29 year old lady with distal radius GCT. We performed a wide resection of the tumor, reconstructed the distal radius with free bula graft and did a wrist arthrodesis using locking compression plate. We found that it provided a stable, painless wrist joint and good functional outcome.
