Arthroscopic dual-bone tunnel repair for palmer type IB injuries of the triangular fibrocartilage complex

BackgroundTriangular fibrocartilage complex (TFCC) injuries, especially Palmer type IB, pose surgical management challenges due to associated distal radial ulnar joint (DRUJ) instability. Traditional surgeries entail risks of complications. Arthroscopic repair presents advantages but lacks consensus on optimal techniques. To evaluate arthroscopic dual-bone tunnel repair in patients with Palmer type IB TFCC injuries of the wrist.MethodsIn this retrospective case series, grip strength ratio, joint range of motion, pain visual analogue scale (VAS), modified Mayo wrist score, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores were assessed before and 12 months after surgery.ResultsThe cohort consisted of 45 patients. At 12 months, the grip strength ratio improved from 0.71 ± 0.08 to 0.93 ± 0.05 (P < 0.001), and wrist joint rotation increased from 126.78 ± 13.28° to 145.76 ± 8.52° (P < 0.001). VAS (1.60 ± 0.58 vs. 6.33 ± 0.91, P < 0.001), DASH (12.96 ± 3.18 vs. 46.87 ± 6.62, P < 0.001), and modified Mayo wrist (88.11 ± 4.43 vs. 63.78 ± 7.99, P < 0.001) scores all improved after surgery. The overall complication rate was 4.44%.ConclusionArthroscopic dual-bone tunnel repair appears to be an effective intervention for alleviating wrist pain, restoring stability, and enhancing joint function in patients with TFCC Palmer type IB injuries.

Effect of the Sauvé–Kapandji method on the wrist contact surface for distal radial ulnar joint disorders

BackgroundThe Sauvé–Kapandji (S-K) method is a surgical procedure performed for chronic deformities of the distal radial ulnar joint (DRUJ). Changes to the joint contact surface from pre- to postoperatively under physiological in vivo conditions have not yet been determined for this useful treatment. The aim of the present study was therefore to compare the articular contact area of the wrist joint between before and after the S-K method for DRUJ disorders.MethodsThe SK method was performed for 15 patients with DRUJ osteoarthritis and ulnar impaction syndrome. We calculated the Mayo Wrist Score as the patient’s clinical findings and created 3-dimensional bone models of cases in which the S-K method was performed and calculated the contact area and shift in the center of the contact area using customized software.ResultsThe Mean modified Mayo Wrist Score improved significantly from 60.3 preoperatively to 80.3 postoperatively (P < 0.01). Scaphoid contact area to the radius increased significantly from 112.6 ± 37.0 mm2 preoperatively to 127.5 ± 27.8 mm2 postoperatively (P = 0.03). Lunate contact area to radius-ulna was 121.3 ± 43.3 mm2 preoperatively and 112.5 ± 37.6 mm2 postoperatively, but this decrease was not significant (P = 0.38). Contact area ratio of scaphoid to lunate increased significantly from 1.01 ± 0.4 preoperatively to 1.20 ± 0.3 postoperatively (P = 0.02). Postoperative translations of the center of the scaphoid and lunate contact areas were decomposed into ulnar and proximal directions. Ulnar and proximal translation distances of the scaphoid contact area were 0.8 ± 1.7 mm and 0.4 ± 0.6 mm, respectively, and those of the lunate contact area were 1.1 ± 1.7 mm and 0.4 ± 1.1 mm, respectively. This study revealed changes in wrist contact area and center of the contact area before and after the S-K method.ConclusionThese results may accurately indicate changes in wrist joint contact area from pre- to postoperatively using the S-K method for patients with DRUJ disorder. Evaluation of changes in contact area due to bone surface modeling of the wrist joint using 3DCT images may be useful in considering surgical methods.

Normative Data of Carpal Bone Measurements in the Sample Adult Indian Population.

Introduction Radiography is the most often accessible and affordable imaging modality. Accurate assessments of wrist X-rays can aid in the diagnosis and prognostic evaluation of various wrist problems. This study aims to identify normal radiographic anthropometry reference values and variations of carpal bones and joints by gender and age in sample Indian population, with the potential to be clinically applicable. Materials and Methods Two investigators conducted a prospective analysis of normal wrist radiographs in a single center. Radiology Information Systems and Picture Archiving and Communication Systems were used to collect standard digitized normal X-rays without significant osseous pathology over a year. We conducted measurements of length, angles, and indices in a standard posteroanterior and lateral wrist X-rays in order to establish the standard dimensions and variances based on age and gender. Results A total of 18 measurements which included eight linear measurements, eight angles, and two ratios were documented. A total of 500 X-rays of 250 males and 250 females with 125 of each in two age groups of 20 and 40 years and 41 and 60 years were evaluated. Conclusion This work is a comprehensive database of the Indian population measuring parameters in normal wrist radiographs of posteroanterior and lateral views. The results of our study indicate that men and younger individuals had a significantly higher carpal height ratio. The width of distal radial ulnar joint space was significantly lesser in older subjects. Additionally, males showed a significantly higher lunate uncovered ratio and radial height. When compared to the literature, the study revealed a significant positive ulnar variance in elderly people and women. However, we noted an overall increase in the percentage of positive ulnar variance individuals in our study. We also recorded a marginal increase in radial inclination with no variations across gender and age.

Determination of Distributional Characteristics and Efficacy of Hand Radiographic Damage in Patients with Rheumatoid Arthritis Using a Novel Damage Assessment Method

Background: The purpose of this study was to identify the distribution characteristics of radiological damage to the hand of rheumatoid arthritis patients and evaluate its effectiveness using a new damage assessment method.Methods: Hand radiographs of a total of 127 rheumatoid arthritis patients were evaluated. We simplified the pre-existing van der Heijde modified total sharp score to assess the extent of bone damage. We selected 36 joints in both hands as regions of interest in our own way, and the erosion and joint space narrowing were scored.Results: When the erosion and joint space narrowing score values of each joint of the hand were added together, the joint space narrowing score was higher than the overall erosion score. We can see that the scaphoid,lunate,radius and ulnar joints have higher erosion scores, and the 4th proximal interphalangeal (PIP), Scaphoid, Lunate, and Radius joints have higher joint space narrowing scores than other joints. These damage assessment results were similar to the results from the previous damage assessment model.Conclusions: The joint space narrowing score is higher than the erosion score, suggesting that joint space narrowing precedes erosion. When checking the hand X-ray of rheumatoid arthritis patients, it is necessary to carefully check the scaphoid,lunate,radius and ulnar and 4th PIP joints, which relatively high radiographic damage scores. Also, the damage assessment model used in this study is relatively simple and does not show difference in analysis results from existing assessment models, so it can be considered for application in follow-up research.

Erratum: Chronic Volar Distal Radial Ulnar Joint Dislocation: A Case Report with Proposed Treatment Algorithm

A New Arthroscopic Classification of Triangular Fibrocartilage Complex Disorders.

Introduction The use of wrist arthroscopy has become a prerequisite for diagnosis and treatment of triangular fibrocartilage complex (TFCC) disorders. Since Palmer's landmark paper, many new arthroscopic descriptions of TFCC tears have been published but there is no currently available updated comprehensive arthroscopic classification of TFCC lesions. Purpose We recently described the arthroscopic anatomy of the TFCC as viewed from a 3-4 portal. Our purpose was to propose a new TFCC disorders classification based on this new arthroscopic TFCC description. Methods We included all currently described TFCC disorders to the best of our knowledge into our arthroscopic, functional, and vascular anatomical concept. We also included patient's specific ulnar variance and distal radial ulnar joint coronal inclination as baseline treatment-oriented parameters. The fresh or chronic, reparable or nonreparable nature of some types of TFCC tears were considered as separate parameters. Results The proposed classification includes disc "D" (degenerative or traumatic), reins "R" (traumatic), and wall "W" (traumatic) lesions. Combined lesions of those three parts of the TFCC may be easily identified. This new classification should facilitate future analysis of isolated or combined TFCC disorders whether they are degenerative and/or traumatic. Discussion The authors present a new three-dimensional-three-part arthroscopic updated description of TFCC disorders with relevance to etiology and treatment principles.

To compare the functional and radiological outcome between external fixation and volar plating for the treatment of intraarticular distal end radius fractures

Background: Fracture of distal radius may be stable that is extra-articular, non-comminuted without distal radio ulnar joint disruption or unstable that is intra-articular, comminuted displaced with distal radio ulnar joint disruption. Complications of unstable fractures are shortening due to bone loss or due to resorption of the cancellous bone from metaphysis, resistant deformity, residual pain, late collapse, radio carpal arthritis and gross functional impairment. Aims and Objective: The purpose of this study to compare the relative efficacy of external fixation versus plating with regard to functional and radiological outcome. Materials and Methods: Total of 60 patients having intraarticular distal end radius fracture were included in this study and was equally divided into two groups, one group treated by external fixator other group with volar locking compression plate with or without augmentation by k-wire. Follow-up was done after 2 weeks, 4 weeks, 6 weeks and 3 ,6 and 12 months. The radiological evaluation was performed with Sarmiento’s Modification of Lindstrom’s Criteria. With the Modified Mayo Wrist Score, the patient’s functional outcomes were assessed and both groups were compared. Results: In this study we found that volar plate group had good to excellent outcome in 73% cases and 07% with fair outcome however with external fixator group found good to excellent in 50% cases and poor in 17% cases. Conclusion: In our study, we showed that the use of an external fixator and a volar locking plate for the treatment of intraarticular distal radial fractures were reliable. The relative simplicity of use, low surgical exposure, and decreased surgical trauma are benefits of external fixation. Despite these volar locking plates augmented with or without k wire had a good to excellent results in terms of early rehabilitation and less complications related to wrist joint. External fixator with ligamentotaxis provide significant good results in communited intraarticular distal end radius fracture.

Treatment of Early Undifferentiated Chronic Monoarthritis of the Wrist by Arthroscopic Wrist Synovectomy Combined with Partial Denervation.

Undifferentiated chronic monosecarthritis (UCMA) is a group of inflammatory joint diseases that has the potential to progress to other diseases and can seriously affect patients' quality of life. There is yet no unified consensus regarding treatment of UCMA. This study aimed to investigate the efficacy of arthroscopic synovectomy combined with partial wrist denervation in treating Larsen 1-3 UCMA. In this case series, we reviewed 14 patients with UCMA treated by arthroscopic synovectomy combined with partial denervation from February 2017 to June 2020. The mean duration of symptoms was 17.4 months (range, 4-60 months), and the mean follow-up was 13.3 months (range, 6-23 months). The anterior and posterior interosseous nerves were severed at the distal forearm, and the radiocarpal, midcarpal, and distal radial ulnar joint synovial membranes were arthroscopically resected at the wrist. The clinical evaluation indices included the visual analogue scale score (VAS) for pain, grip strength, range of (active) motion of the wrist, total active motion, and Mayo wrist score. Larsen's scoring method was used as the imaging evaluation index. At the last follow-up, significant clinical improvements were observed in the visual analogue scale (VAS) score for pain (6.0 (5.0-6.3) vs 1.0 (1.0-2.3), P = 0.001) and Mayo wrist score (42.1 ± 9.7 vs 61.8 ± 12.3, P < 0.0001). No significant changes were found in grip strength (15.9 ± 4.5 vs 16.6 ± 4.7, P = 0.230) or the flexion-extension arc (58.9 ± 39.0 vs 64.3 ± 36.5, P = 0.317), although the mean and median did show positive changes. Among the three patients who showed progress in imaging, there was no significant difference in their pain and functional scores compared to those who did not progress. One patient underwent total wrist fusion 17 months after the operation. Arthroscopic wrist synovectomy combined with partial wrist denervation can provide sustained pain relief and functional recovery for patients with Larsen 1-3 UCMA.

Post-traumatic distal ulnar bifurcation in children: a case report

BackgroundGaleazzi fracture dislocation is a compound injury that encompasses fractures of the distal third of the radius and dislocation of the distal radial ulnar joint (DRUJ). Clinically, this condition is rare and often leads to distal ulnar bifurcation. In previous similar reports, patients were effectively managed through surgery.Case presentationIn this case report, we describe an 11-year-old male child who presented with an ulnar bifida following trauma to the hand, and was treated with manipulation and conservative treatment without surgery. A follow-up performed over the years demonstrated that the patient recovered well, and had normal wrist movements without significant pain, and the patient expressed great satisfaction.ConclusionsUlnar diaphyseal fracture may occur in children or adolescents due to injuries, and may be accompanied with manipulation and repositioning. Conservative treatment can be applied to avoid the trauma associated with surgery especially in the absence of severe joint mobility impairment with good outcomes.

117. Comparative Analysis of Two Hemiarthroplasty Techniques for Symptomatic Distal Radial Ulnar Joint

PURPOSE: Young patients are not impervious to distal radioulnar joint (DRUJ) instability, deformities, and pain. The purpose of this study was to compare and assess the superiority of two techniques of hemiarthroplasty for the treatment of symptomatic DRUJ in a young cohort. METHODS: Thirty-four hemiarthroplasties were performed between 2010 and 2020 by three surgeons at one tertiary medical center. Patients were identified retrospectively and stratified into two groups by implant type: partial ulnar head (A), and Pyrocarbon MCP (B) (off label) (Image 1). Demographics and outcomes were extracted from the electronic medical record. RESULTS: Between the two groups, objective measures of wrist range of motion, grip strength, and pain showed similar findings with improvement across all categories. Statistically significant findings were observed with respect to reduction in pain in both groups as well as improvement in wrist flexion in the pyrocarbon group. Post-operative complications warranting surgical intervention occurred in 10 patients. Of these ten were 2 in the ulnar head implant group; pain and reduced range of motion necessitated one revision to an Aptis implant and one revision to a pyrocarbon implant. In the Pyrocarbon group, 8 surgical interventions were required: 3 pinning in supination for reduced range of motion, 1 exchange with a smaller size implant due to pain, 1 addition of meniscal allografting for pain, and three conversions to Aptis implants for pain and instability. CONCLUSIONS: Painful DRUJs in young patients warrant a surgical intervention which preserves stability and provides longevity with possibility for revision during their lifetime. Hemiarthroplasty allows for preservation of stability, seen in 33/34 patients in this study, with improved symptom management which was seen in 29/34 patients. This study found equal efficacy of the standard ulnar head implant to that of the off-label use of the MCP Pyrocarbon implant. However, the osteointegration of the partial ulnar head implant means future revision would have increased risk of complication. As well, the metallic head of the partial ulnar head implant is known to cause osteolysis of the radial fossa making it less ideal for young patients with future decades of implant wear. Due to these limitations and the similar efficacy, we recommend the use of this prothesis in young patients with symptomatic DRUJ.

A salvage procedure: Radial head excision in children and adolescents-short-to-midterm outcomes and overview of the literature.

Purpose of the study was to report the outcomes after radial head excision in children and adolescents in addition with a review of the current literature. We report a series of five children and adolescents, who had undergone a post-traumatic radial head excision. Clinical outcomes were evaluated in terms of elbow/wrist range of motion, stability, deformity and discomforts or restrictions at two follow-up points. Radiographic changes were evaluated. Patient's age at time of the radial head excision averaged 14.6 (13-16) years. Mean time from the injury to the radial head excision was 3.6 (0-9) years. Follow-up I averaged 4.4 (1-8) years and follow-up II 8.5 (7-10) years. At follow-up I, patients showed an average elbow range of motion of 0-10-120° Ext/Flex and 90-0-80° Pro/Sup. Two patients reported discomfort or pain at the elbow. Four (80%) patients had a symptomatic wrist with pain or crepitation at the distal radio ulnar joint. In three (60%) of them, an ulna plus at the wrist was present. Two patients required ulna shortening and autograft stabilization of the interosseous membrane. At final follow-up, all patients reported full functioning with daily activities. Restrictions were present with sport activities. Functional results at the elbow joint might be improved and pain syndromes lessen due to the radial head excision. Problems at the wrist are likely secondary to the procedure. A critical analysis of other options should be performed ahead of the procedure and a careless application should be avoided by all means. IV.

The distal radio ulnar joint: a journey of discovery and invention of the Aptis prosthesis.

This article describes the journey the authors took in discovering a new distal radioulnar joint prosthesis. The beginning deals with the problems we can potentially create for patients when we blindly follow the literature without any critical thinking. By challenging the established thinking on the function of the forearm, a new way of looking at the distal radioulnar joint emerged. Through trial, error and a moment of desperation, a new solution was found that allow us to relive pain and improve function for our patients with distal radioulnar joint pathologies.

Chronic Monteggia in pediatric population: A narrative literature review.

Monteggia lesion is a traumatic condition that affects the forearm and is characterized by the association of an ulna fracture with a dislocation of the radius capitellar and proximal radius ulnar joints in the majority of cases. Although several authors have contributed to the understanding of this pathology over the years, it remains a challenge for orthopedists, and if not recognized and treated properly, it can have serious consequences. In these cases, a chronic injury develops, which is even more difficult to manage in terms of timing and treatment options. A narrative review of the literature on missed elbow injuries in children was conducted, and chronic Monteggia was the most frequently encountered injury. The analysis of the articles attempts to clarify some points and draw general conclusions on which to reflect.

An Analysis of Extensor Carpi Ulnaris Groove Morphology and Tendon Instability.

The extensor carpi ulnaris (ECU) tendon has a distinct subsheath at the distal ulna. Symptomatic tears of this subsheath and subluxation of the ECU tendon often require reconstruction. We sought to determine the anatomical constraints of the ECU subsheath. The ECU subsheath was exposed on 12 fresh-frozen upper extremities. The tip of the ulnar styloid, the distal ulnar joint surface, and the proximal extent of the distal radio-ulnar joint were identified and dimensions measured. Subluxation of the tendon was then assessed with and without an intact subsheath in 9 specimens. The travel of the tendon was measured in pronation through supination and flexion before and after sectioning of the subsheath. The ECU subsheath is 8.9 mm (standard deviation [SD] = 0.8 mm) wide proximally and 9.0 mm (SD = 1.2 mm) distally. The distal ulnar insertion is 0.5 mm (SD = 0.8 mm) proximal to the tip of the styloid, and stretches 10.2 mm (SD = 2.7 mm) proximally. From maximum pronation to maximum supination and flexion, the ECU tendon traveled 3.32 mm (SD = 4.24) medially when the subsheath was intact and 5.42 mm (SD = 5.0 mm) after sectioning. The maximum depth of the ulnar groove was 2.5 mm (1.59-3.56 mm). There was no significant association between changes in ECU subluxation and the depth of the ECU groove (Spearman's rho = 0.25). The ECU subsheath is roughly 1 cm square stretching proximally from the ulnar styloid. ECU groove depth is not a significant independent predictor of tendon subluxation.

Analysis and validation of a 3D finite element model for human forearm fracture.

Most researchers have performed finite element (FE) analysis of the human forearm fracture by exploring the strength and load transmission of the bones. However, few studies concentrated a complete simulation of the whole forearm complex including ligaments. This paper aims to investigate the load transmission through the bones, contact stress at the joints and strain in the ligaments by using an elaborate FE model, further validating the fracture condition for human forearm. The interosseous ligament was separated into three regions based on the distance to the proximal and distal ends. The FE simulation results were slightly more or less than a previous experimental data in the literature, but generally provided a close approximation of the bone and ligament behaviors. Compared with the experiment results under different loading conditions, maximum contact stress at the proximal radio ulnar joint (PRUJ) and distal radio ulnar joint (DRUJ) of the simulations was higher with an average of 13.4%, and peak strain in the interosseous ligament (IOL) was lower with an average of 11.0%. Under 10kg load, the maximum stress in the radius (2.25 MPa) was less than double the value in the ulna (1.43 MPa). Finally, the FE model has been validated with the onset and location of the Colles' fracture in the literature. This study will provide a great benefit in terms of surgical and medical applications related to forearm fracture that require an extensive knowledge of the behavior of the bones and ligaments under various loading conditions.

A rare case of synovial chondromatosis of distal radio-ulnar joint.

IntroductionSynovial chondromatosis (SC) is a benign metaplastic proliferation of cartilaginous nodules within the synovial membrane that commonly manifests as “loose masses” in the joint space. Synovial chondromatosis affects 1.8 per 1 million individuals. The most common articulations affected are the knees, followed by the hip, elbows, and shoulder. The wrist, on the other hand, is rarely affected. Synovial chondromatosis occurs mostly in the third or fifth decade of life.Presentation of caseA 30-year-old Saudi, non-married female patient presented to the outpatient orthopaedic clinic complaining of right wrist pain for 5 years. The pain started gradually with on and off pain episodes. Her magnetic resonance imagining was ordered which showed large radio ulnar joint effusion associated with synovitis with multiple low- intensity foci corresponding to subtle calcifications which are all consistent with synovial chondromatosis which was successfully treated with surgery. Eventually, the patient reported that her quality of life was hugely improved especially in terms of pain, stiffness, and range of motion.ConclusionSynovial chondromatosis in radio-ulnar joint is a very rare entity. Surgical exploration of the joint, removal of loose bodies alone or combined with synovectomy, is the recommended treatment.

Outcomes following Distal Radioulnar Joint Arthroplasty in the Setting of Total or Partial Wrist Fusion.

Purpose To evaluate the functional outcome and complications following primary ulnar head or total distal radial ulnar joint (DRUJ) arthroplasty in patients who have a partial or total wrist fusion. Methods We conducted a retrospective review of 33 primary DRUJ implants in 31 patients who had a partial or total wrist fusion. Follow-up time averaged 67 months. There were 11 partial and 22 total wrist fusions with 22 ulnar head prosthesis and 11 total DRUJ implants. The mean age of the patients was 49 years. Eighty-one percent had previous surgeries with an average number of 4.6 previous wrist procedures. Pre- and postoperative pain levels were recorded. Mayo Wrist Scores were calculated. Grip strength, range of motion (ROM), and post-operative complications were noted. Results The pain scores improved in 67% of the patients. The Mayo Wrist Score improved significantly from a mean of 39 preoperatively to 51 postoperatively. The grip strength and pro-supination remained stable. The wrist ROM also remained stable in the patients with partial wrist fusions. During the follow-up period, 10 (30%) of the DRUJ implants were explanted, with a trend toward higher explantation rates in total wrist fusions with one in the partial fusion group and nine in the total wrist fusion group. Four of the explantations happened in the first postoperative year. Nineteen (61%) of the patients required a second surgery for a DRUJ implant-related complication; this rate was similar between the partial and total fusion groups. Conclusions DRUJ replacement resulted in improved pain scores and Mayo wrist scores in the majority of patients; however, the combination of primary DRUJ arthroplasty and total wrist fusion was associated with high complication rates. Surgeons should be aware of the high complication rate seen with DRUJ arthroplasty when combined with total wrist fusion.

Elbow Dislocation with Irretrievable Rotating‐Rope Injury of the Forearm: Case Report and Literature Review

BackgroundSimultaneous dislocation of the elbow, radioulnar joint and proximal radius fracture with rotary noose injury to the medial ulna tubercle is extremely rare. An emergency surgery was performed to reduce it. The radial head with the backbone was reset after two hammers were fixed, then the radial capitulum safety was fixed with a locking plate. After the ulnar instability was examined, two Kirschner wires were drilled percutaneously to fix the elbow flexion at 100° under closed reduction, and two Kirschner wires were drilled percutaneously to fix the ulnar joint. Good follow‐up results were achieved. To the best of our knowledge, this is the first report on this particular type of injury and on this approach to treating this type of injury.Case presentationWe report the case of a 36‐year‐old male, who extended and landed on his left hand to protect his child in right arm before felling, resulting in severe pain and deformity of his left elbow and wrist and loss of movement in these joints. X‐ray examination found proximal distal radioulnar joints, a proximal radial fracture and a dislocation bowstring in the ulna nodule. For a timely diagnosis in an emergency open reduction situation, accurate judgment of this injury is highly important. After 12 months of postoperative follow‐up, the patient was symptom‐free, and radiographs showed fracture healing.ConclusionWe performed emergency reduction and internal fixation of the elbow and successfully saved elbow function, no stability decrease and movement restriction. This case also provides a new reference for the treatment of this type of elbow fracture dislocation.

Application of Nanofiber Material Based on Electrospinning Technology in Sports Rehabilitation of Basketball Player’s Wrist Joint

Wrist joint plays an indispensable role in our daily life. The injury of wrist joint has a great influence on the fine movement of the hand and upper limb. For example, you cannot do joint movements, you cannot carry things, and life is very inconvenient. It is necessary to distinguish the types of wrist disorders and take effective rehabilitation methods in time. Wrist joint has a great impact on people’s life and work, and the rehabilitation of wrist joint has become a research hotspot in rehabilitation medicine and medical engineering. Carpal tunnel syndrome is the most common peripheral nerve entrapment disease in clinical practice, with a very high incidence. According to data, the incidence of carpal tunnel syndrome in the general population abroad is 1%‐5%, while that in special populations is as high as 14.5% above. In order to solve the problem of rehabilitation of wrist joint, using electrospinning technology, the polymer solution is prepared into nanofiber materials with strong adsorption and good filterability under the action of high‐voltage electric field. And using some small‐sized nanofibers that are similar to organs in shape and structure, as well as their excellent degradability and biocompatibility, this material is used in the research of wrist joint movement rehabilitation. In this paper, sports rehabilitation training is carried out on the wrist joint of basketball players, and the nanofiber material is effectively combined with sports rehabilitation training. By comparing the rehabilitation of athletes who did not use nanofiber materials, the role of nanofiber materials in sports rehabilitation was studied. This article analyzes the three parts of the radial joint, the wrist joint, and the ulnar joint before and after the sports rehabilitation training for basketball players with functional impairments and compares the sports rehabilitation of the basketball players without nanofiber materials. This article analyzes the three parts of the radial joint, the wrist joint, and the ulnar joint before and after the sports rehabilitation training for basketball players with functional impairments and compares the sports rehabilitation of the basketball players without nanofiber materials.
