Comparative Study
BACKGROUND
Midcarpal arthrodesis is a treatment of choice in patients with midcarpal arthritis. Traditionally a four corner fusion has been favoured, however recent research has shown improved results when the triquetrum and scaphoid are excised. There is no clear evidence as to which remaining bones should be fused or which implants should be used. The purpose of this study is to compare the biomechanics of midcarpal arthrodesis after scaphoid and triquetrum excision, using memory staples or cannulated screws, in recognised construct patterns.
METHODS
36 identical sets of carpal bones were 3D printed from acetyl butyl styrene. Midcarpal arthrodeses were performed in three configurations with shape memory alloy staples or headless compression screws. This gave 6 treatment groups; lunocapitate single staple or screw, lunocapitate with 2 staples or screws, three corner fusion with 2 staples or screws. Peak torque to distraction was measured and analysed.
RESULTS
The peak torque to distraction was significantly greater in almost all constructs utilizing screws compared to staples, with two lunocapitate screws having the highest peak torque at both 1 and 3 mm distraction with 244 Nmm and 749 Nmm respectively (p < 0.05).
CONCLUSIONS
Constructs utilizing screws have a peak torque to distraction significantly higher when compared to staples. Our recommendation when performing a midcarpal arthrodesis after scaphoid and trapezium excision is to fuse the midcarpal joint with 2 headless compression screws.

Arthrodesis of the thumb metacarpophalangeal joint: Conventional open technique with a locking plate or compression pins versus minimally invasive technique with compression pins or screws.
Arthrodesis of the thumb metacarpophalangeal (MCP) joint usually leads to satisfying results when performed with an open technique. The main complication is adhesion of the extensor tendons that sometimes requires hardware removal associated with tenolysis. The goal of this study was to assess whether a minimally invasive technique could reduce the risk of this complication. Arthrodesis of the thumb MCP was performed using an open technique with a locking plate or compression pins in 12 cases (group I) and using a minimally invasive technique with compression pins or screws in 12 cases, for a total of 24 patients aged 48.9 years on average, among which 15 were women. At the last follow-up, the average pain level was rated at 2/10 in group I and 2.3/10 in group II. The QuickDASH was 40.70/100 in group I and 36.24 in group II, grip strength was 79% of the contralateral side in group I and 51% in group II. Pinch strength was 81% of the contralateral side in group I and 45% in group II. Fusion was achieved in all cases in group I and in 7 of 12 cases in group II. Surgical revision for non-union was needed in 5 cases in group II, with hardware removal and tenolysis performed in 2 cases. The non-unions were observed in non-rheumatoid cases. While the two groups were not identical, arthrodesis of the thumb MCP using a minimally invasive technique with compression pins or screws seems to give satisfying results for rheumatoid cases in which no cartilage remains.

BACKGROUND
Arthrodesis of finger joints is often the last line of treatment of severe pain due to osteoarthritis, rheumatoid arthritis, or mallet finger. At the Department of Orthopedic and Hand Surgery, Örebro University Hospital (ÖUH) in Sweden, the Kirschner-wire technique was standard until 2020, when the headless compression screw technique was introduced as a complement. There is no consensus on which method is superior. The purpose of this study was to examine the outcomes and complications associated with distal interphalangeal (DIP) joint and thumb interphalangeal (IP) joint arthrodesis, and to see whether these correlated with patient-dependent and treatment-related factors.
METHODS
In a retrospective cohort study, we evaluated a total of 149 consecutive arthrodeses (118 DIP joint and 31 thumb IP joint) performed between 2012 and 2022. The primary outcome was risk factors for complications after arthrodesis.
RESULTS
Osteoarthritis was the most common indication (56%) for arthrodesis. The majority of the patients were females (74%), and the median age was 62 (range 18-86). The complication frequency was 35%, with infection being the most common (25%). Time to completed follow up was < 12 weeks in the majority of the cases (58%). There were no significant differences in complication rate between the 136 joints operated using Kirschner wire and the 13 joints operated using headless compression screws. There was no significant increased risk of complications among smokers or patients with rheumatoid arthritis. Diabetes and surgeon experience had a significant influence on the risk of complication (p = 0.036 and p = 0.006, respectively).
CONCLUSIONS
Osteoarthritis was the most common indication for arthrodesis and postoperative complications occurred at a rate similar to that reported in the existing literature. Diabetes and surgeon experience were identified as factors increasing the risk of postoperative complications in these DIP/thumb IP joint arthrodeses. However, there was no significant difference between the two techniques (Kirschner wire and headless compression screws) regarding complications. Further studies are needed in order to determine the optimal type of operation and choice of implant.

Review
In ankle arthrodeses several clinical and biomechanical studies have shown the superiority of the screw technique over external fixation. As a maximum of stability is a major goal, especially for functional after-treatment or in patients with poor bone stock, the arthrodeses technique at Hannover Medical School is performed with four screws. Two parallel anterior/posterior screws are placed from the tibia to the talus, providing anterior stabilization. One screw posteriomedial has a posterior tension-wiring effect and one screw placed through the fibula to the talus acts against rotational and sagittal translation. From May 1975 to May 1995, 225 ankle arthrodeses with internal or external fixation technique were performed. Complications were found in 47% in the external fixation treatment group (n = 44) and in 10% the patients stabilized with the screw technique (n = 181). Fifty of these 225 patients had a follow-up evaluation after an average of 7.4 years (external fixation, n = 22; screw fixation, n = 28). All patients were examined and scored with three different scoring systems: (1) MHH Score, (2) Clinical Rating System according to Kitaoka et al. (1994) and (3) Outcome Questionnaire for evaluating the overall outcome. The results from the questionnaire were compared to the clinical scores. Retrospective analysis revealed a higher rate of complications for arthrodeses performed by external fixation. The overall results of all three different scoring systems showed a trend in favor of the screw-fixation technique without reaching statistical significance (P > 0.05). The results of the Outcome Questionnaire are statistically as valid as the two clinical scoring systems.

BACKGROUND
Proximal interphalangeal joint (PIPJ) arthrodesis can provide reliable pain relief and restore hand function in patients with PIPJ arthritis. However, there is a paucity of literature on patient-specific preoperative risk factors that are associated with adverse outcomes after PIPJ arthrodeses. Therefore, the primary purpose of this study was to assess preoperative predictors of nonunion and reoperation after PIPJ arthrodesis.
METHODS
This study identified all patients who underwent PIPJ arthrodesis at a single community practice between 1987 and 2013. The final analysis included 415 PIPJs treated with arthrodesis. The mean follow-up was 1.3 years. Data on preoperative diagnosis, demographics, comorbidities, and operative techniques were recorded, as well as the occurrence of nonunions and reoperations. Logistic regression models were used to identify independent risk factors of nonunion and reoperation.
RESULTS
There were 40 nonunions (10%) and 62 reoperations (15%). Of the reoperations, there were 39 incidences of isolated hardware removal, 9 irrigation and debridement, 8 amputations, 5 revision arthrodeses, and 1 corrective osteotomy. The highest number of nonunions occurred in the traumatic diagnosis group (37%), followed by the rheumatoid group (23%) and the scleroderma group (15%). The highest number of reoperations occurred within the traumatic joint disorder group (40%), followed by the rheumatoid group (24%) and the scleroderma group (11%). Multivariate analysis revealed that male sex ( < .01) and hepatic disease ( = .03) were significant risk factors of nonunion. Male sex was also significantly associated with increased reoperation risk ( < .01).
CONCLUSION
Risks of nonunions and reoperations after PIPJ arthrodeses are low; however, these findings may guide clinicians and patients in the preoperative decision-making process and help with targeted postoperative surveillance to mitigate these risks.

Comparative Study Randomized Controlled Trial
BACKGROUND
Arthrodesis is the current treatment for end-stage hallux rigidus, although there are many reports advocating total joint replacement arthroplasty. The aim of this randomized controlled trial was to evaluate clinical outcomes after first metatarsophalangeal joint (MTPJ) arthrodesis and replacement arthroplasty.
METHODS
Between November, 1998, and January 2001, 63 patients between the ages of 34 and 77 years, with unilateral or bilateral MTPJ arthritis were recruited and randomly selected to have either MTPJ arthrodesis or arthroplasty. Twenty-two patients (38 toes) had arthrodesis and 27 patients (39 toes) had arthroplasty. A single surgeon performed all surgery. The primary outcome measure determining successful surgery was a decrease in pain as measured on a Visual Analogue Scale (VAS). Functional outcome was assessed at 6 months and 1 and 2 years. Cost data were simultaneously collected.
RESULTS
At 24 months, pain improved in both groups (p < 0.001), but there were significantly greater improvements after arthrodesis (p = 0.01). All 38 arthrodeses united at a mean dorsiflexion angle of 26 degrees, with few complications. In contrast, in the arthroplasty group, six of the 39 inserted implants had to be removed because of phalangeal component loosening. In the remainder the range of motion gained was poor, and the patients tended to bear weight on the outer border of their foot. The cost ratio was 2:1 in favor of arthrodesis.
CONCLUSIONS
Outcomes after arthrodesis were better than those after arthroplasty. The results were partially attributable to an unacceptably high incidence of loosening of the phalangeal components, which resulted in removal of the implants. However, even when data from the failures were excluded, arthrodesis was clearly preferred by most patients.

Comparative Study
BACKGROUND
Arthrodesis of the first metatarsophalangeal joint is a commonly performed orthopaedic procedure. The optimum method of fixation and joint surface preparation has yet to be determined.
METHODS
This study compared four fixation techniques: Biomechanical grade sawbones were used. The dorsal plate used was a titanium, anatomically contoured locked plate. Testing was performed using an Instron machine applying force from the plantar aspect of the fused joint. Each fused sample was tested to failure. Stiffness, as calculated from the force-displacement curve, and ultimate load tolerated were recorded for each sample. The method of failure of each sample was also documented.
RESULTS
Constructs arthrodesed using dorsal plate with separate screw groups, regardless of method of joint preparation, were the stiffest (p<0.001). The weakest construct was dorsal plate alone without interfragmenary screw. There was no difference in stiffness between planar and cup-cone joint preparation (p=0.99). Maximum load tolerated was similar when comparing Crossed Screws with dorsal plate with screw with either cup-cone or planar reaming (p=0.93, p=0.89 respectively). Dorsal plating alone tolerated a significantly lower maximum load than Plate with Screw Groups or Crossed Screws (p<0.001).
CONCLUSION
This study confirms that an IFS combined with a dorsally positioned locked-plate is the ideal construct, with the joint preparation technique of little consequence.

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. III.

The goal of this study was to describe the long-term functional outcomes of the procedure described by Dubert (stabilized arthroplasty with intermetacarpal arthrodesis) for painful carpometacarpal impingement of the little finger. Between 2005 and 2017, 8 patients (1 woman and 7 men) were operated on who had a mean age of 38 years (24-53 years). Seven cases were post-traumatic (malunion) and one was due to septic arthritis. A total of 5 patients were available for a retrospective clinical, functional, and radiological follow-up at a mean of 73 months (23-108 months). Clinical parameters included pain on VAS, grip strength, Quick Disability of Arm, Shoulder and Hand questionnaire, Patient-Rated Wrist Evaluation, and a subjective hand value (0-100%). Fusion was achieved in all cases. Of the 8 patients, one developed complex regional pain syndrome and one had persistent pain that required secondary proximal metacarpal resection. At the last follow-up, all patients were satisfied and reported a significant reduction in pain and improvement in strength. Mean Quick Disability of Arm, Shoulder, and Hand questionnaire, Patient-Rated Wrist Evaluation and subjective hand value were 19/100 points, 21/100 points and 75%, respectively. Our study suggests that the stabilized arthroplasty of the fifth finger, as describe by Dubert, is an efficient and reliable method to reduce pain and improve hand function in patients suffering from carpometacarpal impingement of the little finger.

Veterinary and Comparative Orthopaedics... 2015To describe the use of the Fixin locking plate system for stifle arthrodesis in dogs and to retrospectively report the clinical and radiographic outcomes in six cases.
OBJECTIVES
To describe the use of the Fixin locking plate system for stifle arthrodesis in dogs and to retrospectively report the clinical and radiographic outcomes in six cases.
MATERIALS AND METHODS
Medical records of dogs that had arthrodesis with the Fixin locking plate system were reviewed. For each patient, data pertaining to signalment and implant used were recorded. Plate series and thickness, number of screws placed, number of cortices engaged, and screw diameters were also recorded. The outcome was determined from clinical and radiographic follow-ups. Radiographic outcomes assessed included the measurement of the postoperative femoral-tibial angle in the sagittal plane.
RESULTS
Six dogs met the inclusion criteria for the study. Mean body weight was 13 kg (range: 3 - 34 kg). Radiographic follow-up (mean: 32 weeks, range: 3 - 52 weeks) was available for all dogs. In one case, an intra-operative complication occurred. In another case, a tibial fracture occurred 20 days after surgery. All arthrodeses healed and no implant complication was detected although all cases had mechanical lameness.
CLINICAL SIGNIFICANCE
Stifle arthrodesis can be performed successfully using a Fixin locking plate system.
