RESUMEN
BACKGROUND: Osteoarthritis (OA) contributes increasingly to disability worldwide. There is ample high-quality research on the treatment of knee and hip OA, whereas research on surgical and non-surgical treatment in hand OA is sparse. Limited evidence suggests that education and exercise may improve pain, function, stiffness, and grip strength in hand OA. The established surgical options in hand OA have disadvantages. Prostheses preserve motion but have a high complication rate, whereas fusions decrease function due to limited movement. There is an unmet need for high-quality research on treatment options for hand OA and a need for the development of effective and safe movement-sparing therapies. This study aims to compare the effects of a motion-preserving surgical treatment (denervation of the proximal interphalangeal (PIP) joint) with a patient education and exercise program on patient-reported outcomes and objective function in painful PIP OA. METHODS: In this parallel-group, two-armed, randomized, controlled superiority trial (RCT), 90 participants are assigned to surgical PIP joint denervation or education and exercise. Pain on load 1 year after intervention is the primary outcome measure. Secondary outcome measures include pain at rest, Patient-Rated Wrist and Hand Evaluation (PRWHE), HQ8 score, EQ5D-5L, objective physical function, complications, two-point discrimination, Mini Sollerman, consumption of analgesics, and the need for further surgery. Assessments are performed at baseline, 3 and 6 months, and 1 year after intervention. DISCUSSION: There are no previous RCTs comparing surgical and non-surgical treatment in PIP OA. If patient education plus exercise or PIP denervation improve function, these treatments could be implemented as first-line treatment options in PIP OA. However, if denervation does not achieve better results than non-surgical treatment, it is not justified to use in PIP OA.

Background: Intra-articular fractures of the proximal interphalangeal joint (PIPJ) can result in poor outcomes if inadequately treated. Dynamic external fixation and internal fixation with plates and/or screws are two treatment options. The role of combining these two methods is unclear. The aim of this study is to determine the outcomes of patients with intra-articular fractures of the PIPJ treated with a combination of dynamic external fixation with a plate and/or screws. Methods: A retrospective review was conducted on 18 consecutive cases of intra-articular fractures of the PIPJ treated with pins and rubber band traction system (PRTS) combined with dorsal internal fixation with plates and/or screws. The patients' average age was 51 years (range: 20-81 years). The fracture patterns were volar-type (n = 2), dorsal-type (n = 4) and pilon-type (n = 12). Data with regard to time to surgery, interphalangeal joint range of motion, grip strength, VAS for pain, Quick DASH score, complications, duration of follow-up and return to work were collected. Results: The levels of articular involvement were stable (n = 1), tenuous (n = 5) and unstable (n = 12). The average time to surgery was 9 days, and the average follow-up period was 15 months. The fracture was fixed with a dorsal plate and screws in 10 patients and with only screws in eight patients. All patients had PRTS. All patients returned to their original occupation and the fractures united in good alignment. The average grip strength was 86% of that of the unaffected side. The average active PIPJ motion was 85° (range: 50°-106°), and the average active distal interphalangeal joint (DIPJ) motion was 48° (range: 10°-90°). Conclusions: Our results show that a combination of PRTS and open reduction and fixation with plate and/or screws achieved a good range of motion and articular reduction. Level of Evidence: Level IV (Therapeutic).

Mucous cyst is a benign but recurrent lesion. It is located on the dorsal surface of the digital extremity between the distal interphalangeal joint and the base of the nail. The nail is often affected by the cyst because of its topographical proximity. Nail plate deformity may even be the first obvious abnormality indicating the presence of a small mucous cyst or subungual cyst. Mucous cyst is associated with osteoarthritis of the joint, osteophytes probably being the main contributing factor. Surgical treatment by joint debridement and cyst removal is the most effective way of preventing recurrence.

PURPOSE: There is no consensus on the optimal treatment of bony mallet finger in the paediatric population due to a lack of studies in children. The Ishiguro technique is simple and less invasive, and treatment with K-wire fixation seems to provide better results for extension lag in bony mallet finger according to the literature. A retrospective cross-sectional study with long-term follow-up was performed to evaluate the functional and clinical outcomes of this method in children. Preoperative and intraoperative predictors of outcome were investigated. METHODS: From June to December 2022, we evaluated 95 children who underwent extension K-wire block from 2002 to 2012. Eighty-four children were included (mean age 14.8 ± 1.68 years) for a mean long-term follow-up of 11.6 ± 2.3 (8-16) years. Clinical and radiographic features were assessed. Pain and functional outcomes were assessed using Crawford criteria, range of motion (ROM) at the distal interphalangeal joint (DIPJ), loss of extension, and VAS scale. Univariate and multivariate regressions were used to assess which variables might predict the worst outcomes at long-term follow-up. RESULTS: Bone union and pain relief were always achieved. There were no complaints of potential growth impairment or nail deformity. 82.1% of patients showed excellent and good results. Fifteen patients had fair results. CONCLUSIONS: Although there are currently no significant differences between surgery and orthosis in adults, the Ishiguro technique is more effective in children when it comes to outcomes in the treatment of mallet fingers. A high percentage of excellent and good results were achieved, and no epiphyseal damage or nail deformity was reported. A strong and significant correlation was found between the worst outcomes and either delayed treatment time or excessive flexion angle.

BACKGROUND: Bony defects in finger injuries and infections impose high demands on their treatment due to the close anatomic relationships. Ideally, the injuries are entirely treated in emergency care. Due to the mechanism of the accident, contaminated and compromised soft tissues are often present and set limits to single-stage treatment. We present the long-term subjective and functional results after two-stage reconstruction of bony finger joint defect injuries. PATIENTS AND METHODS: Over a period of 15 years, a total of 40 patients with 43 fingers were treated due to a defect injury in the phalanges. Initially, the finger was stabilised with Kirschner wires after debridement. After consolidation of the soft tissue, the bone was reconstructed in a subsequent operation by interposition of an iliac crest graft. Complications occurred in 9 patients. Twenty-five patients with 27 fingers were followed up for 10.3 years. Range of motion, length of the affected finger, and grip force, each in relation to the contralateral extremity, were recorded. In addition to a subjective assessment of the global result, the daily function was determined by means of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS: Significant differences compared with the contralateral extremity (p<0.05) were found in length (70 mm; 91.0%) and total mobility of the affected finger (95°; 46.0%), hand span when the thumb was involved (202.5 mm; 93.4%), and power grip when one of the fingers was injured (30 kg; 84.1%). The DASH score was 4.2 points (0-55.8). Subjectively, 88% of patients were satisfied with the treatment outcome. CONCLUSION: In case of contaminated and compromised soft tissues, the two-stage treatment of bony defect injuries in finger joints by arthrodesis of the joint is a reliable treatment strategy. In the long run, it results in a very satisfactory function of the hand in everyday life although significant differences have been measured compared with the contralateral extremity.

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. TRIAL REGISTRATION: Researchweb CRIS #280,998, 26th of July 2023.

RATIONALE: The conventional treatment of giant cell tumors is intralesional curettage with local adjuvant therapy. Because hand tumors have a high local recurrence, the primary goal for treating tumors of the hand is to eradicate the lesion. PATIENT CONCERNS: To preserve the metacarpophalangeal (MCP) joint function as well as avoid further recurrence after surgery. DIAGNOSES: The giant cell tumor invades the patient's MCP joint in an index proximal phalanx. INTERVENTIONS: Using computer-aided design and three-dimensional printing techniques, we reformed the original shapes of the MCP joint and its peripheral bone to replica models. The surgeon then performed an en bloc resection and proximal phalanx with MCP joint reconstruction by fabricating the patient's costal osteochondral graft during the operation. OUTCOMES: After 6 months of rehabilitation, the patient's finger functions could pinch and grasp objects naturally. At the 1-year follow-up, the range of motion of the MCP, proximal interphalangeal, and distal interphalangeal joints improved from flexion of 35° to 60°, 75° to 85°, and 60° to 80°, respectively. The hand function achieved the mean performance of non-preferred hands for young females at the postoperative 3-year follow-up. LESSONS: The customized prototyping technique has the potential to replica the original patient's bony graft to reach the goal of minimizing the defects at the donor site and maximizing the function of the reconstructed MCP joint.

The complete loss of finger extension leads to significant inconvenience in daily life and often requires surgical treatment. Despite some disadvantages, the Boyes method, which uses the flexor digitorum superficialis tendon, is commonly performed for complete extensor rupture. We report the case of a 73-year-old woman living alone diagnosed with a subcutaneous rupture of all extensor tendons from the index to the little finger. The favourable range of motion of her wrist allowed us to perform extensor tenodesis. Additionally, the patient had a dislocated thumb interphalangeal (IP) joint, enabling us to use the extensor pollicis longus tendon for tendon transfer in combination with thumb IP joint fusion. The patient demonstrated favourable finger range-of-motion outcomes at the 6-month postoperative assessment. The case shows that extensor pollicis longus tendon transfer and tenodesis may be a viable treatment option for patients with complete extensor rupture accompanied by thumb IP joint deformity and normal wrist range of motion.

Background: This study aimed to evaluate the efficacy of ulnar superficial slip resection (USSR) for improving hand function after unfavourable results after triggering finger release using a minimally invasive approach. Methods: We evaluated 17 consecutive fingers of 16 patients who complained of unfavourable outcomes after primary trigger finger release. The chief complaints of the two index and 15 middle fingers were proximal interphalangeal (PIP) joint pain during movement, flexion contracture of the PIP joint and snapping at the A2 pulley in eight, seven and two fingers, respectively. The joint arc of the active range of motion and extension loss of the PIP joint, grip strength, visual analogue score (VAS) of PIP joint pain and Quick Disability of the Arm, Shoulder and Hand were evaluated before and after surgery. Results: Thirteen fingers could release joint contracture and snapping by the USSR procedure. However, four fingers of three patients required total flexor digitorum superficialis resection to resolve the unsatisfactory conditions of the intraoperative decision. The joint arc of active range of motion and extension loss of the PIP joint, grip strength and VAS score significantly improved (mean of 16.1 months follow-up). Finally, 15 patients (88.2%) were satisfied with the symptom relief outcomes. Conclusions: USSR is an effective and satisfactory procedure for unfavourable conditions after trigger finger release, including PIP joint pain, joint contracture and snapping at the A2 pulley. Level of Evidence: Level IV (Therapeutic).

This case report describes the 4-year outcomes of proximal interphalangeal joint arthroplasty in a 14-year-old girl with a stiff joint after trauma. At follow-up, active range of motion was 35°, she was pain-free and satisfied with the outcome. Implant arthroplasty seems to be a valuable option for young patients with persistent post-traumatic stiff and deviated PIP joints to-at least temporarily-increase quality of life.

During the postoperative hand rehabilitation period, it is recommended that the repaired flexor tendons be continuously glided with sufficient tendon excursion and carefully managed protection to prevent adhesion with adjacent tissues. Thus, finger joints should be passively mobilized through a wide range of motion (ROM) with physiotherapy. During passive mobilization, sequential flexion of the metacarpophalangeal (MCP) joint followed by the proximal interphalangeal (PIP) joint is recommended for maximizing tendon excursion. This paper presents a lightweight device for postoperative flexor tendon rehabilitation that uses a single motor to achieve sequential joint flexion movement. The device consists of an orthosis, a cable, and a single motor. The degree of spatial stiffness and cable path of the orthosis were designed to apply a flexion moment to the MCP joint prior to the PIP joint. The device was tested on both healthy individuals and a patient who had undergone flexor tendon repair surgery, and both flexion and extension movement could be achieved with a wide ROM and sequential joint flexion movement using a single motor.

Painful arthritis of the small joints of the hand is a common condition affecting older adults, with distal interphalangeal joint and thumb carpometacarpal joint being the two most common locations. Younger adults may also develop painful arthritis after trauma and with inflammatory arthropathy. Traditional surgical approaches address the structure of the joints with either arthrodesis or arthroplasty with or without an implant. In recent decades, denervation has been reported as an alternative treatment for painful small joints that are mobile and stable. Publications on denervation often report faster surgery and recovery times than traditional surgeries that manipulate the small joint bony structures. This article reviews the history, anatomy, surgical techniques, and outcomes of denervation of the small joints of the hand.

PURPOSE: The purpose of this study was to assess the long-term clinical, subjective, and radiographic results of pyrocarbon hemiarthroplasty for proximal interphalangeal joint (PIPJ) arthritis at a single institution. METHODS: Patients treated with a pyrolytic carbon hemiarthroplasty between 2005 and 2015 were contacted for a clinical follow-up visit. Patients were assessed before surgery, one year after surgery, and again after a mean of 11 years (range: 6-16 years). Objective outcomes were assessed with grip strength, pinch strength, and range of motion (ROM). Subjective outcomes were assessed by the Disabilities of the Arm, Shoulder, and Hand score, Canadian Occupational Performance Measure (performance and satisfaction), and Visual Analog Scale pain scores at rest and during activity. Radiographic assessments were completed according to Sweets and Stern as modified by Wagner et al. RESULTS: A total of 68 fingers in 52 patients underwent PIPJ hemiarthroplasty. Thirty-six arthroplasties in 29 patients were available for the long-term follow-up, five patients had died, and the remaining cases were contacted by phone. Three cases were lost to follow-up. Preoperative diagnoses included 41 fingers with osteoarthritis or posttraumatic arthritis, and 27 fingers with inflammatory arthritis. Eight cases had undergone revision at the time of follow-up, and the 10-year implant survival was 72%. The revisions were performed after a mean of two years after surgery. Three patients had undergone soft-tissue procedures. Visual Analog Scale pain scores, Disabilities of the Arm, Shoulder, and Hand scores, and Canadian Occupational Performance Measure scores improved significantly compared with that before surgery. Grip strength and pinch grip remained unchanged. However, PIPJ ROM deteriorated significantly one year after surgery, when compared with that before surgery. CONCLUSIONS: Pyrocarbon hemiarthroplasty of the PIPJ has an acceptable long-term implant survival, and the significant improvement in pain scores and patient-reported outcomes is maintained over time. Pyrocarbon hemiarthroplasty could be a viable option in the management of PIPJ arthritis. Patients should be advised that PIPJ ROM deteriorates over time. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

SUMMARY: Correction of a boutonnière deformity is one of the most demanding challenges in hand surgery. Surgical interventions are usually considered when functional use of the finger cannot be obtained after intense hand therapy. The authors introduce their newly described lambda (λ) repair, which is an easy-to-learn, straightforward surgical technique. The method involves an end-to-side tenorrhaphy of the lateral bands, resembling the Greek λ. Patients who underwent a lambda repair were retrospectively evaluated with preoperative and postoperative measurements of proximal interphalangeal (PIP) joint movement. Four patients (two male, two female; median age, 35.5 years) with a median follow-up period of 9.1 months were included. Three patients underwent lambda repairs for isolated boutonnière deformities, and one patient received a vascularized free toe transfer combined with a lambda repair. The preoperative average PIP joint extension lag or deficit was 28.75 degrees and could be reduced to 15 degrees. Preoperative average PIP joint active flexion was 60 degrees, which was improved to 88.75 degrees. No complications were observed. The lambda repair is a new tool in the reconstruction of boutonnière deformity, further expanding the armamentarium of hand surgeons.

BACKGROUND: The treatment for proximal interphalangeal joint (PIP) stiffness in extension requires extensor tenolysis, concomitant procedures to restore flexion, and intensive therapy. A stiff swan neck deformity without articular involvement is rare and the treatment is always challenging. METHODS: Six patients with stiff swan neck deformities were operated between 2016 and 2023, and the outcome was analyzed retrospectively. A dorsal capsule release and radial lateral band translocation volar to the PIP joint axis were done. This translocation was maintained by a sling formed by the flexor digitorum superficialis and the free margins of the accessory collateral ligament. The range of movements in the PIP joint, visual analog scale (VAS), and functional outcomes were analyzed by the Michigan Hand Outcome Questionnaire (MHOQ) score. RESULTS: The mean follow-up was 49.5 months (range 48-52 months). The mean preoperative PIP joint extension was 8 (range 5-10) degrees of extension), and the mean preoperative PIP joint flexion was 0. All patients improved after the surgery and the mean flexion of the PIP joint at follow-up was 95 degrees; extension was 1 degree (range 0-5 degrees). The mean Michigan Hand Outcomes Questionnaire (MHOQ) score was 92 (range 90-95) and the VAS was 0. CONCLUSIONS: Dorsal capsule contracture release and lateral band translocation to the volar axis of the PIP joint seem to be the possibilities for correcting stiff swan neck deformity. LEVEL OF EVIDENCE: IV, retrospective case study.

INTRODUCTION: Mallet fingers are the most common tendon injuries of the hand. Bony avulsion distal finger extensor tendon ruptures causing a mallet finger require special attention and management. In this monocentral study, we analyzed the clinical and individual outcomes succeeding minimal invasive k-wire extension block treatment of bony mallet fingers. MATERIALS AND METHODS: In a retrospective study, we sent a self-designed template and a QUICK-DASH score questionnaire to all patients, who were treated because of a bony mallet finger between 2009 and 2022 and fulfilled the inclusion criteria. A total of 244 requests were sent out. 72 (29.5%) patients participated in the study. Forty-five men and twenty-seven women were included. RESULTS: 98.7% (n = 75) of the cases were successfully treated. Patients were highly satisfied with the treatment (median 8.0; SD ± 2.9; range 1.0-10.0). Based on the QUICK-DASH score, all patients showed no difficulties in daily life. The extent of avulsion did not influence the outcome. CONCLUSION: We conclude that the minimally invasive treatment of a bony mallet finger should be offered to every patient, because it is safe, fast, and reliable. Thus, we propose to perform extension-block pinning independently of the articular area.

Multiple fracture patterns can occur around the proximal interphalangeal joint and require surgeons to have a thorough understanding of the anatomy, clinical and radiographic examination, common fracture patterns, surgical and nonsurgical treatment options, and potential complications. Proximal phalangeal condylar fractures are typically managed surgically, because even nondisplaced fractures have a propensity for displacement. Middle phalangeal base fractures most commonly present as a volar lip fracture with or without dorsal subluxation or dislocation. Treatment options include extension block splinting or pinning, transarticular pinning, open reduction and internal fixation, external fixation, volar plate arthroplasty, and hemihamate arthroplasty. Less common fractures include dorsal lip fractures with or without volar subluxation or dislocation (the central slip fracture), lateral plateau impaction or avulsion injuries, and pilon fractures. The main goals in the management of middle phalangeal base fractures are to restore articular congruency and initial early range of motion, which are more important than obtaining an anatomic reduction.
