ABSTRACT
BACKGROUND: The main objective of the present study was to present the biomechanical properties of the wrist in patients who underwent scaphotrapeziotrapezoid arthrodesis when compared to a healthy control hand. METHODS: The study group consisted of 29 consecutive patients who underwent a scaphotrapeziotrapezoid wrist arthrodesis at least 1 year before the research onset. Both hands of all patients were examined in 4 main categories. RESULTS: Average score obtained in the VAS, before the surgery, without motion of the wrist was 5.21 (SD = 3.04), whereas with wrist motion, it was 8.10 (SD = 1.37). Nineteen (65.52%) patients exhibited weakened wrist muscle strength. After the surgery, only 5 (17.24%) patients declared pain in the wrist. Furthermore, the results obtained in the VAS statistically significant differed from the ones before (p < 0.05). Twenty-eight (96.55%) patients were able to resume their profession. Twenty-seven (93.10%) patients stated that they would opt for the operation again. The peak torque during the analysis of extension of the wrist in the isometric protocol was found to be 8.1 Nm (SD = 2.9), 7.9 Nm (SD = 2.3), and 7.9 Nm (SD = 2.5) in the operated hands and 10.9 Nm (SD = 3.2), 9.6 Nm (SD = 2.9), and 9.1 Nm (SD = 3.8) in non-operated hand for 30° extension, no-flexion, and 30° flexion positions, respectively (p < 0.05). CONCLUSION: The current study is the first to present the biomechanical parameters of flexor and extensor muscles of the wrist and fingers in patients after the said procedure. Biomechanical assessments with additional isometric, isotonic, and isokinetic tests provide an opportunity to objectify treatment outcomes and guide appropriate rehabilitation by monitoring its effects.

Volar dislocation of the trapezoid is a rare injury and is easily missed. It is more common to have a dorsal dislocation of trapezoid or multiple carpometacarpal joint dislocations. The rare nature of the injury also means that there is little guidance in literature regarding optimal treatment. We are reporting the presentation, management and a 3-year follow-up of this rare injury in a 19-year-old male. Level of Evidence: Level V (Therapeutic).

Osteogenic sarcoma is a malignant tumor that rarely affects the hand. When it does, it most often involves the phalanges or metacarpal heads. We present the case of a 51-year-old woman with a low-grade osteosarcoma affecting the trapezium bone of her left hand. A total trapeziectomy with partial removal of the first metatarsal, scaphoid, trapezoid, and capitate bones was performed, and no adjuvant therapy was administered. Six years after the intervention, the patient is disease-free, with excellent functionality and yearly imaging tests showing no signs of recurrence.

Background: The purpose of this study was to describe the technique of arthroscopic resection of the scaphoid head and evaluate both the clinical and radiographic results of scapho-trapezium-trapezoid osteoarthritis cases. Methods: Seventeen cases (13 men and 4 women) with a mean age of 57 years (24-74 years) were operated on from 2002 to 2015. Inclusion criteria were nontraumatic radial-sided wrist pain without improvement after 4 months of conservative treatment and positive radiographic images demonstrating the presence of osteoarthritis. All cases were evaluated preoperatively and postoperatively using visual analog scale, wrist range of motion (ROM), grip strength, and patient's work status (Mayo Wrist Score). Disabilities of the Arm, Shoulder, and Hand (DASH) and Patient-Rated Wrist/Hand Evaluation (PRWHE) questionnaires were also administered. The technique consisted of performing a 3- to 4-mm round-shaped scaphoid head resection via arthroscopy while preserving the scaphotrapezial and scaphocapitate ligament insertions. Results: At an average follow-up of 24 months, all the patients were satisfied. The results showed statistically significant improvement in pain at rest (P = .001), under maximal load (P = .0001), and in Mayo Wrist Score (MWS) (P = .0001). Wrist ROM, grip strength, DASH, and PRWHE showed an improvement without reaching statistical significance. The mean preoperative radiolunate (RL) X-ray measurement angle was 17° (-10° to 35°). The postoperative mean value was 25° (0°-45°). In the preoperative radiographic evaluation, 11 cases exceeded the "critical" 15° RL angle. At follow-up, the RL angle increased in 10 cases and remained unchanged in 7 cases. None of these cases became symptomatic. Transitory neurapraxia of the dorsal superficial branch of the radial nerve was observed in 1 case. Damage of the dorsal branch of the radial artery was immediately fixed. Conclusions: Arthroscopic resection of the distal portion of the scaphoid due to scapho-trapezium-trapezoid osteoarthritis demonstrated an effective and safe technique with less complications than open surgery.

INTRODUCTION: Trapezoidal fractures account for only 0.4% of all carpal bone fractures. Owing to their rarity, there is paucity in the literature regarding the clinical findings and treatment. This paper aims to summarize the current understanding of trapezoidal fractures and present a novel classification algorithm. METHODS: A diagnostic classification algorithm was created based on the known blood supply and ligamentous attachment of the trapezoid. The proposed treatment algorithm was then applied to trapezoidal fractures in the literature to validate the algorithm and determine whether patients received treatment that was in accordance. RESULTS: A total of 19 articles, representing 22 trapezoidal fractures were included, with two additional cases presented by the authors. Presenting symptoms were pain (nâ¯=â¯21) and swelling (nâ¯=â¯12). Diagnosis was made on CT in a majority of the time, 79.2% (nâ¯=â¯18). All outcomes were favorable with symptomatic resolution and full range of motion after treatment, except in four patients that had co-existing wrist injuries. When the algorithm was applied, 89.5% (nâ¯=â¯17) of the patients received treatment in accordance with the proposed algorithm and demonstrated good outcomes. In the remaining patients (nâ¯=â¯2) whose treatment differed, one had diminished grip strength and the other was lost to follow-up. CONCLUSIONS: Given a degree of clinical suspicion including a history of blunt trauma to the hand and persisting pain, trapezoidal fractures should remain on the differential when plain radiographs fail to identify any fracture. Operative treatment is suggested if there is any significant displacement, compromise of the dorsal surface, or breech of the trapezoidal ligaments causing possible dislocation. LEVEL OF EVIDENCE: IV - Diagnostic.

We performed a systematic review to find out the safety and efficacy of various procedures for isolated scaphotrapeziotrapezoid osteoarthritis. Eleven articles were included. The most common procedure was arthroplasty with pyrocarbon implant (28%), followed by resection of distal pole of scaphoid with proximal trapezium and trapezoid resection (18%). The other procedures included trapeziectomy with ligament reconstruction and tendon interposition (LRTI) (14%), arthroscopic resection of distal scaphoid (11%), trapezium and trapezoid resection with LRTI (10%) and arthrodesis (10%). Complications were noted in 18 (15%) patients. The most common complication (7.5%) was asymptomatic dorsal intercalated segmental instability (DISI) followed by dislocation of the pyrocarbon implant (3%). Fusion resulted in decreased range of motion and grip strength. The distal scaphoid resection was related to high rate of DISI. Although the pyrocarbon implant has a higher dislocation rate which requires revision surgery, this complication is avoidable with good surgical technique. Arthroplasty with pyrocarbon implant may be the first choice in younger patients.

BACKGROUND: The aim of the study was to evaluate patient reported outcome measures (PROM) before and after trapeziectomy with or without ligament reconstruction and tendon interposition for trapeziometacarpal joint arthritis with special focus on possible differences due to gender, age and surgical method. METHODS: Data from the Swedish quality registry for hand surgery (HAKIR) was analyzed preoperatively, 3 months and 1 year postoperatively for 1850 patients (mean age 63 years, 79% women). RESULTS: One year postoperatively, mean pain at rest was reduced from 50 to 12 of maximum 100. However, pain on load and weakness had not abated to the same extent (mean 30 and 34 of 100, respectively). The mean improvement in PROM did not differ between age groups or gender. The result was similar after trapeziectomy with ligament reconstruction and tendon interposition (86% of the patients) and simple trapeziectomy but few patients were operated with the latter method. CONCLUSION: Pain on load and weakness remains to some extent 1 year after surgery for trapeziometacarpal joint arthritis. The result is similar after trapeziectomy with or without ligament reconstruction and tendon interposition and the same improvement can be expected after surgery regardless of age and gender.

PURPOSE: Thumb carpometacarpal (CMC) joint arthroplasty is one of the most commonly performed surgeries by hand surgeons. A large portion of these patients also have scaphotrapezoidal (ST) arthritis in addition to CMC arthritis. The purposes of this study were to quantify the amount of transverse trapezoid resection necessary to prevent ST impingement and to compare an oblique with a transverse osteotomy of the trapezoid. METHODS: A total of 9 cadaveric specimens were used and were randomly placed into 2 groups. Group 1 had sequential transverse osteotomies and the space between the scaphoid and trapezoid was measured in various wrist positions. Group 2 had oblique osteotomies and the ST distance was measured in multiple wrist positions. RESULTS: In group 1, there was no contact between the scaphoid and trapezoid in neutral wrist position after any resection. The half and two-thirds transverse osteotomies did not have contact at 20° radial deviation (RD) and 30° wrist flexion (WF). In 1 of the 5 specimens, there was contact at one-third resection in either isolated RD or WF. In 3 specimens, there was contact at one-third resection with 20° of radial deviation combined with 30° WF. In group 2, there was no contact in any specimen in any wrist position tested. At neutral, there was 3.7 mm of space between the scaphoid and trapezoid measured at the radial side. In 20° RD and 0° WF, an average space remaining was 2.8 mm. In 0° RD and 30° WF, there was an average space of 2.3 mm remaining. At 20° RD and 30° WF, there was an average space remaining of 1.8 mm. At the extreme of RD and WF, there was an average space remaining of 1.4 mm. CONCLUSIONS: An oblique osteotomy of the trapezoid did not have any ST contact in 20° RD and 30° WF. The transverse osteotomies had contact with only one-third resection. Therefore, if a transverse osteotomy of the trapezoid is performed, more than one-third of the bone should be resected to minimize the risk for bony impingement in positions of WF, RD, or both. CLINICAL RELEVANCE: In ST arthritis, an oblique osteotomy of the trapezoid may prevent impingement while allowing for less overall bony resection compared with a transverse osteotomy.

BACKGROUND: The purpose of this study was to investigate scaphoid motion within the scapho-trapezio-trapezoidal (STT) joint during wrist motion in the presence of STT joint osteoarthritis (OA). METHODS: We studied 11 wrists with STT OA and 5 normal wrists. Computed tomography (CT) images were acquired in five wrist positions (maximum active flexion, extension, radial deviation, ulnar deviation, and neutral position). The 3-dimensional surface models of the radius and scaphoid were constructed and the motion of scaphoid relative to the radius was calculated. RESULTS AND CONCLUSIONS: During wrist flexion/extension motion, the scaphoid rotated mostly in the flexion/extension plane. The angle tended to be smaller in STT OA than in normal. During wrist radioulnar deviation, the scaphoid was in an extended position in neutral wrist in STT OA. The motion of scaphoid in STT OA was divided into two types: a rigid type and mobile type. The mobile type rotated closer to the flexion/extension plane than the rigid type. Taking into account scaphoid motion during wrist movement before surgery may provide better results in the treatment of STT OA.

Isolated scaphotrapeziotrapezoid (STT) osteoarthritis has functional consequences on the wrist. The main objective of our study was to evaluate the functional outcomes of patients managed surgically during the last 12 years at the Toulouse University Hospital, regardless of the surgical technique used, for isolated STT osteoarthritis. We performed a single-center retrospective observational study using the CCAM database. The inclusion criteria were patients treated surgically for isolated STT osteoarthritis who did not respond to conservative treatment, with at least 6 months of clinical and radiological follow-up. Twenty-four patients were treated between 2006 and 2018. Partial arthroplasty of the distal pole of the scaphoid with or without interposition and total trapeziectomy had been performed on these patients. The mean follow-up was 79±46.8 months. The wrist range of motion (ROM) and the Kapandji score were not significantly reduced postoperatively. The mean postoperative QuickDASH score was 29.15±8.46. The mean pain assessed using a visual analog scale was 6.6±1.17 preoperatively versus 1.25±1.51 postoperatively (P=0.003). Statistical subgroup analysis found no predictive factor for a better postoperative QuickDASH score, and no surgical technique was superior at halting the progression of intracarpal misalignment and postoperative ROM. Surgical treatment of isolated STT osteoarthritis resistant to conservative treatment leads to significant functional improvement, particularly in terms of pain, without altering the wrist's overall mobility.

Scaphotrapeziotrapezoid (STT) arthritis occurs commonly with basal joint arthritis, but can also occur in isolation or in conjunction with other patterns of wrist arthritis, such as scapholunate advanced collapse. Surgical options depend on the specific clinical scenario encountered. Isolated STT arthritis was classically managed with arthrodesis, but is now often addressed with distal scaphoid resection (open or arthroscopic), trapeziectomy (partial or complete) and partial trapezoid resection, or implant arthroplasty. Development of postoperative dorsal intercalary segment instability is a notable concern with any of these techniques. STT arthritis in conjunction with basal joint arthritis can be managed effectively with trapeziectomy and either partial trapezoid excision or distal scaphoid excision. STT arthritis with scapholunate advanced collapse is uncommon, but can be managed with proximal row carpectomy or scaphoidectomy and four-corner fusion. If basal joint arthritis is also present, trapeziectomy can additionally be performed, but grip strength is likely to be substantially diminished.

PURPOSE: To assess the feasibility and reproducibility of T2 relaxation time measurements of the trapeziometacarpal joint (TM) and triangular fibrocartilage complex (TFCC) on healthy subjects at 1.5 T MR. MATERIALS AND METHODS: Thirty-four healthy volunteers underwent an axial oblique multislice multiecho spin-echo sequence of the wrist at 1.5 T, with 10 of them having performed another MR scan on a different 1.5 T scanner. Regions of interest were independently manually drawn by two musculoskeletal radiologists to include the cartilaginous part of the TM and TFCC. Intra-observer, inter-observer and inter-scanner reproducibility of T2 relaxation time measurements was tested using the Bland-Altman method. RESULTS: The mean T2 values obtained by the two radiologists were 29.9 ± 6.5 ms and 30.0 ± 6.1 ms in the TM and 24.5 ± 2.3 ms and 24.6 ± 2.8 ms in the TFCC, respectively. The mean values of the second series of T2 measurements obtained by the senior radiologist were 29.9 ± 6.5 ms and 30.0 ± 6.3 ms in the TM and 24.3 ± 2.9 ms in the TFCC. Inter-observer reproducibility in the TM and in the TFCC was 76% and 82%, respectively. Intra-observer reproducibility in the TM and TFCC was 71% and 76%, respectively. Inter-scanner reproducibility of T2 measurements was 36% in the TM and 85% in the TFCC, respectively. CONCLUSION: The assessment of T2 relaxation time measurements of the cartilage of the TM and the TFCC seems to be feasible and reproducible, although the inter-scanner reproducibility of T2 measurements of the TM is suboptimal. Further studies including patients are warranted to prove the utility of this tool.

Degenerative arthritis at the articulation of the scaphoid, trapezium, and trapezoid (STT or triscaphe joint) is a common degenerative disease of the wrist. Pain and weakness with grip strength reduction and functional limitations when performing routine daily tasks are common complaints of patients with STT arthritis. Initial conservative treatments for STT arthritis include splinting, bracing, activity modification, anti-inflammatory medication, and steroid injections for pain relief. Failure of conservative treatment is the main indication for surgery, which may include distal scaphoid excision, with or without filling of the void after excision, trapeziectomy, STT arthrodesis, or STT implant arthroplasty.

BACKGROUND Trapezoid fractures are very uncommon, accounting for less than 1% of all wrist fractures. Isolated fractures of this bone are even more rare, with just a few reports in the literature. The trapezoid bone has a very stable position within the wrist, forming a relatively immobile joint with the second metacarpal base distally. It is also connected by very strong ligaments to the trapezium, capitate and, scaphoid. Trapezoid fractures occur when a strong bending or axial force is applied to the second metacarpal base. CASE REPORT We present a clinical case of an isolated, non-displaced, trapezoid fracture in a young white male, which was treated with cast immobilization for 4 weeks and physical therapy. Complete functional recovery was achieved 3 months after the injury, without any pain or tenderness. CONCLUSIONS Fractures of the trapezoid bone usually have a good clinical outcome. Nonetheless, we need to be very suspicious about this diagnosis since radiography is apparently normal in almost all such cases and clinical examination results may not be entirely clear.

BACKGROUND: First carpometacarpal (CMC) joint osteoarthritis (OA) is commonly encountered in clinical practice. The preferred surgical option when conservative therapy fails varies with the stage and nature of the disease. Denervation of the first CMC joint is a relatively new procedure for managing stable thumb CMC joint OA. Our objective was to review our experience and surgical technique with first CMC joint denervation surgery. METHODS: All patients who underwent first CMC joint denervation surgery from January 2015 through September 2017 were retrospectively identified. Before undergoing surgical CMC denervation, patients received a joint block at the first CMC joint with 0.25% bupivacaine. Only patients with a good response to injection were selected for surgical denervation. Patient demographics, preoperative and postoperative pain scores using a numeric rating scale, and grip strength using the Jamar Hydraulic Hand Dynamometer were analyzed. RESULTS: Of 10 patients (13 hands) with CMC joint OA, 8 patients (11 hands) met the inclusion criteria. Patients' average grip strength improved significantly after the procedure (from 38.4 ± 26.7 foot/lb to 50.2 ± 27.6 foot/lb; P = 0.007). The numeric rating scale pain score improved significantly from 7.8 ± 2.4 to 2.4 ± 1.8 (P < 0.001). Seven of 8 patients reported satisfaction with surgery. There were 2 complications. CONCLUSIONS: First CMC joint denervation provided good pain relief and improvement in grip strength in patients with thumb CMC joint OA. This minimally invasive technique proved to be a good option for providing optimal pain control and improvement in strength with minimal and mild complications.

Background: Wrist pain is often nonspecific. Magnetic resonance imaging (MRI) is regularly obtained to evaluate wrist pain. Variations and pathophysiology identified on MRI may not account for patient's clinical symptoms. This study aims to quantify the prevalence of flexor carpi radialis (FCR) tendinopathy on MRI and the coexistence of trapeziometacarpal (TMC) or scaphotrapeziotrapezoid (STT) osteoarthritis. Methods: Using an institutional research database, we identified 3631 adult patients who obtained an MRI of the wrist during a 15-year period. Text search in the radiology reports identified 302 patients with possible FCR signal abnormalities. After reviewing the medical records, 98 patients were identified with FCR tendinopathy. Furthermore, medical records were used to identify pain located on the volar radial part of the wrist. In the absence of a documented examination consistent with FCR tendinopathy, we considered any signal change in the FCR incidental. Results: We identified 55 patients (55%) with incidental FCR tendinopathy. In a bivariate analysis, we found FCR signal changes on the MRI were associated with older age, white race, clinically suspected FCR tendinopathy, volar-radial sided wrist pain, and TMC and STT arthritis. Using multivariable logistic regression to account for confounding, older age and volar-radial sided wrist pain were independently associated with FCR signal changes on MRI. Conclusions: Signal changes in the FCR are infrequent and often incidental (asymptomatic) or associated with peritrapezial osteoarthritis.
