A Percutaneous Triple K-Wire Fixation Technique for Nascent Malunion of Proximal Interphalangeal Joint Fracture-Dislocation: A Case Series With an Assessment of Functional Outcome

Fracture-dislocations of the proximal interphalangeal (PIP) joint are difficult to manage. In the case of a 2- to 4-week delay in definitive treatment, a nascent malunion may result. This study aimed to evaluate the effectiveness of the percutaneous triple K-wire technique for treatment of the PIP joint nascent malunion. We treated 13 patients with nascent malunion of PIP joint fracture-dislocations using the percutaneous triple K-wire fixation technique based on the principle of soft callus manipulation to achieve congruity and reduction in the joint. The study included cases where the percentage of articular involvement exceeded 40% and in whom there was a minimum follow-up of 12 months. At the final follow-up, we measured the range of motion at the PIP joint. The Ishida and Ikuta scores were determined. The mean period between injury and surgery was 17.2 days. The average follow-up time was 14.2 months. The mean active arc of motion before surgery in the PIP joint was 15 degrees and that at the final follow-up was 83 degrees. Seven patients achieved excellent outcomes according to the Ishida and Ikuta scores. The final postoperative range of motion at the PIP joint was comparable with that reported in the literature for patients who underwent different procedures. This procedure can be considered a viable alternative to open reduction and plating, hemihamate arthroplasty, and ligamentotaxis with distraction, particularly in the presence of nascent malunion.

Volar Plate Draping (VPD) for Severely Comminuted Proximal Phalanx Head Fractures

AbstractWhile proximal phalangeal joint injuries with comminution of the base of the middle phalanx are common injuries, proximal interphalangeal (PIP) joint fracture dislocations with an intact base of middle phalanx and a comminuted head of proximal phalanx are rare. Volar plate arthroplasty and other described techniques prevail for the former injury, while the latter does not have any supportive literature on the exact method of management. We herein present a 20-year-old male with a severely comminuted head of proximal phalanx fracture with dislocation of the PIP joint, which was not reconstructable but was managed successfully with a novel technique of volar plate draping that resurfaced the raw phalangeal head. A 3-year follow-up of the patient, whose finger has full, painless, and complete functional range of movement, gives us the belief that this procedure can provide a fully functional finger where other methods fail to do so.

Can the result of untreated Proximal Interphalangeal fracture-dislocation be satisfied?

Objectives: The aim of this study is to examine the clinical outcomes of untreated proximal interphalangeal (PIP) fracture-dislocations, a condition known to often result in poor outcomes even if treated appropriately. Methods: A retrocpective analysis was conducted on a 22-year-old male patient presenting with an untreated fracture of the fourth finger of his dominant hand. The patient sustained the injury at the age 16, and while initial X-ray images were unavailable, subsequent imaging revealed features consistent with a proximal interphalangeal joint fracture-dislocation. The patient initially received a finger splint following the trauma but susbsequently discontinued its use and failed to attend follow-up controls. Results: Radiographic evaluation revealed deformity at the base of the middle phalanx, characterized by slight dorsal subluxation and dorsal osteophyte formation. However, physical examination revealed no discernible cosmetic or functional deficits, no signs of joint instability, and the range of motion was found to be complete and painless. Conclusion: Despite the absence of conventional tratment, our patient exhibited notably positive clinical outcomes. However, we emphasize the importance of caution against leaving proximal interphalangeal fracture-dislocations untreated, given the lack of definitive evidence supporting this approach.

Proximal Interphalangeal Joint Fractures: Various Approaches to Fixation.

There are numerous operative and nonoperative options for the management of proximal interphalangeal joint fractures and fracture dislocations. The treatment of choice should be guided by the fracture pattern and joint stability. The authors highlight a contemporary option for open reduction and internal fixation techniques, but all the techniques presented are viable options under the right circumstances. It is also important to set patient expectations as most of these patients will note post-injury stiffness and potential functional limitations.

Results of an Adjustable Traction Method Using Surgical Gloves and K-Wires for the Treatment of Proximal Interphalangeal Joint Fracture Dislocation

This study aimed to evaluate an adjustable traction method using surgical gloves and Kirschner wires (K-wires) for proximal interphalangeal (PIP) fracture dislocations and examine the association between a reduction pin and range of motion (ROM), and between subluxation immediately after removal and ROM. Patients who underwent this surgical method for PIP joint dislocation fractures between 2003 and 2017 were included. We retrospectively investigated the postoperative results. We defined patients having surgery within 4 weeks after an injury as fresh cases and after 4 weeks as chronic cases. K-wires were inserted at the center of the proximal phalangeal head and the distal part of the middle phalanx to create a frame, and the finger of the surgical glove was used as a traction-force generator. We analyzed the association of ROM with each finger, age, presence of a reduction pin, and subluxation immediately after frame removal. Overall, 37 fingers were included (27 acute and 10 chronic). The mean age of the participants was 40.0 years (range: 13-72 years). The mean follow-up period was 10.5 months (3-47 months). The final active ROM was -4.6°/94.6° (extension/flexion) for acute cases and -27.0°/73.5° for chronic ones. Active ROM was significantly better in patients with a reduction pin than in those without it. Subluxation immediately after frame removal was not associated with postoperative active ROM. Additionally, all PIP joints with subluxation that occurred immediately after frame removal achieved good joint congruity. The results of the adjustable traction method using surgical gloves and K-wires were satisfactory. Postoperative ROM did not decrease because of the additional reduction pin. Subluxation occurring immediately after frame removal did not affect the ROM, ultimately resulting in good joint congruity. Therapeutic IV.

Trapezium fracture and 1st CMC joint fracture-dislocation: a case report

The thumb and its corresponding joints are important for daily life activities. Although rare, injuries to this apparatus would greatly affect any patient’s quality of life. We present in this article a case of a man who had a traumatic trapezium-thumb metacarpal base fracture-dislocation, a pattern described in the literature with no consenus on the treatment of choice, treated with closed reduction and percutaneous pinning with excellent functional and radiological results.

Various Flexible Fixation Techniques Using Suture Button for Ligamentous Lisfranc Injuries: A Review of Surgical Options.

Contrary to Lisfranc joint fracture-dislocation, ligamentous Lisfranc injury can lead to additional instability and arthritis and is difficult to diagnose. Appropriate procedure selection is necessary for a better prognosis. Several surgical methods have recently been introduced. Here, we present three distinct surgical techniques for treating ligamentous Lisfranc employing flexible fixation. First is the "Single Tightrope procedure", which involves reduction and fixation between the second metatarsal base and the medial cuneiform via making a bone tunnel and inserting Tightrope. Second is the "Dual Tightrope Technique", which is similar to the "Single Tightrope technique", with additional fixation of an intercuneiform joint using one MiniLok Quick Anchor Plus. Last but not least, the "internal brace approach" uses the SwiveLock anchor, particularly when intercueniform instability is seen. Each approach has its own advantages and disadvantages in terms of surgical complexity and stability. These flexible fixation methods, on the other hand, are more physiologic and have the potential to lessen the difficulties that have been linked to the use of conventional screws in the past.

Hemi-hamate arthroplasty for the management of chronic proximal interphalangeal joint fracture dislocations: Analysis of 21 cases in Indian population and review of the literature

BackgroundChronic fracture-dislocations involving the proximal interphalangeal (PIP) joint are challenging cases. We conducted this study to analyze the outcomes following hemi-hamate autograft reconstruction of such injuries and to compare our results with the existing literature. MethodsA retrospective analysis of 21 patients with chronic dorsal PIP fracture-dislocations that were managed with hemi-hamate autograft reconstruction was done. The average articular surface involvement was 64%. The average duration between injury and surgery was 9.4 weeks (range, 6–16). Quick DASH (Disabilities of Shoulder and Hand) scores, VAS (Visual Analog Scale) scores, range of motion of the PIP joints, DIP (distal interphalangeal) joints, and MCP (metacarpophalangeal) joints were measured during serial follow-up visits. ResultsUnion and graft incorporation was seen in all cases. The average Quick DASH score at four weeks post-surgery was 66 and it improved to eight at one year (p-value<0.05). The average VAS score at four weeks post-surgery was 7.66 and it improved to 2.09 at one year (p-value<0.05). The mean flexion of the MCP joint improved from 52.85° at the end of four weeks to 72.38° at one year (p-value<0.05). The average flexion at the PIP joint improved from 10.47° at the end of four weeks to 70.47° at one year (p-value<0.05). The average DIP flexion improved from 38.33° at the end of four weeks to 62.38° at one year (p-value<0.05). The average hand grip strength was 85% of the normal side. ConclusionHemihamate autograft reconstruction is a suitable procedure for the management of chronic PIP joint fracture-dislocations, especially in cases with extensive involvement of the articular surface.

Functional Outcome of Dynamic Distraction External Fixation of Proximal Interphalangeal Joint Fracture-Dislocation

Abstract Introduction: Proximal Interphalangeal (PIP) Joint fracture dislocation commonly observed to involve one or both the condyles of proximal phalanx or base of middle phalanx. Clinical aspects of PIP joint fracture dislocation typically include pain, swelling, and restricted movements over the site of the lesion. Achieving functional and painless range of motion at the PIP joint is a reasonable outcome. The ideal goal for treating these comminuted intra-articular fractures of the PIP joint is to achieve anatomical reduction and stable fixation of the fracture fragments combined with traction followed by early mobilization to prevent joint stiffness. Thereby, the purpose of this study is to evaluate the effectiveness of dynamic external traction systems to allow both reduction of fracture fragments by capsule-ligamentotaxis and early mobilization. Materials and Methods: A total of thirty patients with PIP joint fracture dislocation who were operated with a dynamic external traction system were assessed as a part of the study between the period of December 2019 and July 2021. All the patients included in the study showed a PIP joint fracture dislocation on anteroposterior and lateral radiographs of the 2nd, 3rd, 4th, or 5th phalanx. All patients were operated for PIP joint fracture dislocation with dynamic external traction system under general anesthesia or regional block under fluoroscopy guidance and assessed for functional outcome postoperatively according to Ishida scoring system. Results: According to Ishida scoring system, our study observed 19 (63.33%) cases with excellent outcome, 6 (20%) cases with good, 4 (13.33%) cases with fair, and 1 (3.33%) case with poor outcome compared to a study conducted by Ishida et al., which observed 9 (39.13%) cases with excellent outcome, 6 (26.08%) with good, and 6 (26.08%) with fair outcomes each and 2 (0.08%) cases with poor outcome. Conclusion: In this prospective study, we have concluded that the dynamic distraction external fixation of PIP joint fracture dislocation is a good method for obtaining early rehabilitation of the patient with minimal complications. The technique ensures an anatomic reduction, stable fixation, good union, and early mobilization with good and fast recovery. However, this is a small study and requires a larger sample size for definitive conclusion.

Hemihamate Arthroplasty Revisited: A Retrospective Review of 11 Cases.

Proximal interphalangeal joint (PIPJ) fracture dislocations are complex injuries that can result in persistent pain, stiffness, and angulation. Hemihamate arthroplasty (HHA) can be used to reconstruct the base of the middle phalanx in cases of unstable PIPJ fracture dislocations. Despite previous case series describing good outcomes with HHA, it has not gained widespread use. The purpose of this study is to describe our straightforward, reproducible technique and to demonstrate the benefit in motion after the procedure in chronic unstable PIPJ fracture dislocations. All patients with chronic, unstable PIPJ fracture dislocations requiring joint resurfacing of greater than 40% of the base of the middle phalanx treated with HHA were retrospectively reviewed. Patient demographics, injury features, surgical technique, preoperative and postoperative PIPJ range of motion and arc of motion, time to surgery, and complications were reviewed. Any fracture amenable to fixation or cases with radiographic evidence of arthritis or injury to the head of the proximal phalanx were excluded. Eleven cases were reviewed. The mean patient age was 35 years. The mean time from injury to surgery was 6 months. The mean joint surface involved was 64%. The mean PIPJ arc of motion was 17 degrees preoperatively and 63 degrees postoperatively. The mean bone block size required was 8 × 8 × 8 mm. The mean follow-up was 26 months. Postoperative pain at the PIPJ on the visual analog scale was 0.4 (scale of 0 to 10). Complications included 2 patients requiring tenolysis. Despite the lack of a perfect geometric recreation of the base of the middle phalanx with the hamate, patients recover acceptable PIPJ motion and have minimal pain. Hemihamate arthroplasty is a good option for any patient with minimal motion of their PIPJ and a chronic, unstable fracture dislocation.

Clinical utility of minimally invasive posterior internal fixation within the pelvic ring using S2 alar iliac screws for unstable pelvic ring fracture

IntroductionPosterior internal fixation for unstable pelvic ring fractures is often associated with complications, including pelvic hemorrhage and gluteal necrosis. Pelvic ring fixation using the S2 alar iliac screw (SAIS) without fixation of the lumbosacral vertebrae may have potential as a novel, minimally invasive technique for treating unstable pelvic ring fractures. The present study compared clinical outcomes in patients who underwent SAIS fixation within the pelvic ring with a historical control group of patients who underwent conventional trans-iliac plate fixation for the treatment of unstable pelvic ring fractures. Materials and methodsThirty-two patients diagnosed with unstable pelvic fractures with sacral fracture or sacroiliac joint fracture dislocation were retrospectively evaluated. Eight consecutive patients underwent trans-iliac plate fixation from April 2012 to March 2015, and 24 consecutive patients underwent SAIS fixation from April 2015 to February 2020. Rates of soft tissue complications, intraoperative blood loss, and intraoperative blood transfusion volume were compared in these two groups. ResultsMean intraoperative blood loss was significantly lower in patients who underwent SAIS fixation than in those who underwent trans-iliac plate fixation (141.0 ml vs 315.0 ml; P = 0.027), although there were no between-group differences in intraoperative blood transfusion volume (0.0 ml vs 140 ml; P = 0.105), incidence rate of soft tissue complications (4.2% vs 0%; P = 1.000), and operation time (88.5 min vs 93.0 min; P = 0.862). Bone healing was confirmed in all patients who underwent SAIS fixation without dislocation of the fracture site, whereas one patient who underwent trans-iliac plate fixation experienced a dislocation of the fracture site during follow-up (0% vs 12.5%; P = 0.250). ConclusionsSAIS fixation reduces intraoperative blood loss and ensures bone healing without major complications, including dislocation of the fracture site. SAIS fixation may therefore be an alternative, minimally invasive method of treating unstable pelvic fractures.

Press-Fit Hemihamate Arthroplasty for the Proximal Interphalangeal Joint.

Background Chronic proximal interphalangeal joint fracture-dislocations with articular malunion are complex injuries. Hemihamate arthroplasty is an established technique for the management of both acute and chronic cases but is associated with several complications. We present the clinical experience of modified press-fit hemihamate arthroplasty. Description of Technique The base of the middle phalanx was exposed from the volar side, and the cartilage defect of the proximal interphalangeal joint (PIPJ) was evaluated in the hyperextended position. A bone hole was created slightly toward the volar side to recreate the curvature of the PIPJ. The hemihamate osteochondral graft was harvested and fixed into the bone hole in a press-fit manner without using a screw. The volar plate and flexor tendon sheath were then reattached. Patients and Methods The study included three patients with chronic dorsal fracture-dislocations of the PIPJ. All patients were treated for >6 weeks after the injury (average 11 weeks). Results The average total arc of motion of the affected joint improved from 38 degrees before surgery to 80 degrees after surgery. Radiographically, bone union and congruity of the joint surface were achieved in all the patients. None of the treated patients complained of resting pain and reported minimal pain during activity (average visual analog scale 0.5; range 0-1.4). Conclusions Press-fit hemihamate arthroplasty is a safe and effective procedure for treating chronic PIPJ fracture-dislocations without the risk of screw protrusion.

IntroductionPosterior pelvic ring disruption includes sacral fractures, sacroiliac joint fracture dislocations and ilium fractures. Percutaneous iliosacral screw fixation of sacral fractures and sacraoiliac joint fracture dislocations have been prevailing, it has the advantages of minimal invasiveness, less blood loss and low wound infection rate. HypothesisThis study was to evaluate the application of three-dimensional (3D) printed patient-specific guide template in closed reduction and iliosacral screw fixation of posterior pelvic ring disruption. Material and methodsThe data of patients, who were treated with closed reduction and iliosacral screw fixation of posterior pelvic ring disruption with the assistance of 3D printed guide template from December 2014 to September 2018, were collected. The screw placement time, fluoroscopy time, intraoperative blood loss, fracture reduction, screw position and functional assessment were recorded. ResultsThere were 17 cases of unstable pelvic fractures, and 20 screws were inserted for fixation of sacral fractures or sacroiliac joint dislocations, with bilateral screw placement in 3 cases. The average time for each screw placement was 45.9±8.6min (30–60min). The average fluoroscopy time for each screw insertion was 50.3±19.7s (24–96s). The mean blood loss for each screw placement was 32.0±11.1mL (20–50mL). According to Matta scale, the fracture reduction was graded as excellent in all the 17 cases. According to the modified Gras classification, the 3D CT reconstruction of the pelvis demonstrated grade 1 for 18 screws and grade 2 for 2 screw. Functional outcome 1 year postoperatively was rated as 15 excellent and 2 good, according to the Majeed functional scale. DiscussionIt is feasible and safe to stabilize the posterior pelvic ring disruption using iliosacral screw fixation under assistance of the 3D printed guide template. It could reduce fluoroscopy time, screw placement time and intraoperative blood loss and achieve good postoperative recovery. Level of proofIV; retrospective study.

Comparison of 3 Dynamic External Fixation Devices for Proximal Interphalangeal Joint Dorsal Fracture-Dislocations in a Cadaver Model

Several improvised dynamic external fixation devices are used for treating unstable dorsal proximal interphalangeal (PIP) joint fracture-dislocations. We compared the effectiveness of 3 constructs for simulated dorsal PIP joint fracture-dislocations in a cadaver model. We tested 30 digits from 10 fresh-frozen, thawed cadaver hands. We aimed to remove the palmar 50% of the base of each digit's middle phalanx (P2), simulating an unstable dorsal PIP joint fracture-dislocation. Each PIP joint was then stabilized via external fixation with either a pins-and-rubber-bands construct, pins-only construct, or tuberculin syringe-pins construct. We allocated 10 digits per fixation group. The finger tendons were secured to a computer-controlled stepper motor-driven linear actuator. Via this mechanism, all PIP joints were taken through 1,400 cycles of flexion-extension. With the PIP joint in neutral extension, we measured the P2 dorsal translation at baseline, after fixator stabilization, and after the motion protocol. The actual mean P2 palmar defect created was 48% of the base. All PIP joints were unstable after creating the defect, with a mean initial P2 dorsal displacement of 3.7 mm. After application of the fixators, all PIP joint dislocations were reduced. The median residual P2 dorsal displacements were 0.0 mm for the pins-rubber bands group, 0.1 mm for the pins-only group, and 0.5 mm for the syringe-pins group. There were no cases of PIP joint redislocation after flexion-extension cycling, and the median dorsal P2 displacements were 0.0 mm for the pins-rubber bands group; 0.0 mm for the pins-only group; and 0.5 mm for the syringe-pins group. All 3 external fixators restored PIP joint stability following simulated dorsal fracture-dislocation, with all reductions maintained after motion testing. The syringe-pins construct had significantly greater median residual P2 dorsal displacement after the initial reduction and motion testing, which is of unclear clinical importance. This study informs surgeon decision-making when considering dynamic external fixator options for dorsal PIP joint fracture-dislocations.

218 Compliance With the British Society for Surgery of the Hand (BSSH) Guidelines on the Management of Open Hand Fractures Audit

Abstract Aim British Society of Surgery of the Hand (BSSH) have defined standards for managing open hand fractures. We intended to ascertain our and referring peripheral units’ adherence with BSSH’s standards of care in managing open hand fractures and determine the associated morbidity. Method We performed a 6-month prospective audit reviewing clinical records of patients referred to our department with open hand fractures, to determine whether: antibiotic prophylaxis had been started, and discontinued at definitive closure; wound washout and closure had been performed within 24 hours of injury; patients had continued rehabilitation with hand therapists. Results 25 patients sustained open hand fractures in this period. All patients, except 1 who declined, received antibiotic prophylaxis. 19 (76%) had a wound washout and closure within 24 hours of injury. Antibiotic prophylaxis was discontinued at time of definitive closure in theatre in 3 (12%) patients. The remaining 21 patients continued antibiotic prophylaxis beyond 72 hours. 3 (12%) patients developed a wound infection, 2 (6%) of these requiring debridement and irrigation in theatre. Both patients had proximal interphalangeal joint fracture dislocations who underwent a wound debridement within 24 hours of injury, 1 of which was secondary to an animal bite. 22 (88%) patients attended their hand therapy appointment. Conclusions The incidence of deep infection requiring subsequent operative debridement remains low in open hand fractures, despite the substandard adherence to BSSH’s recommendations. Educating colleagues will improve the adherence to guidance. The BSSH hand injury triage app fulfils this purpose. We intend to raise awareness and encourage its use.

Hamate vs. capitate grafting for proximal interphalangeal joint fracture-dislocation: an MRI-based study of 35 hands.

We examined the MRI scans of 35 adult hands to assess the feasibility of the hamate and the capitate as potential donor grafts in the management of comminuted intra-articular fractures at the base of the middle phalanges. Essentially neither the hamate nor the capitate were perfect anatomic matches in most digits, but the capitate had the advantage of having more uniform facets, and the capitate facet shapes were similar to those of the little finger. The measurement of angles in the coronal and sagittal plane showed that in some respects the differences between the potential graft and the base of the middle phalanges were smaller for the capitate than for the hamate. Moreover, the sagittal morphology of the capitate made it less prone to joint overstuffing than the hamate. We conclude that the capitate may be considered as a graft donor in selected cases, especially for the little finger.

ResultsThere were 17 cases of unstable pelvic fractures,and 20 screws were inserted for fixation of sacral fractures or sacroiliac joint dislocations, with bilateral screw placement in 3 cases. The average time for each screw placement was 45.9±8.6min (30–60min). The average fluoroscopy time for each screw insertion was 50.3±19.7s (24–96 s). The mean blood loss for each screw placement was 32.0±11.1ml (20–50ml). According to Matta scale, the fracture reduction was graded as excellent in all the 17 cases. According to the modified Gras classification, the 3D CT reconstruction of the pelvis demonstrated Grade 1 for 18 screws and Grade 2 for 2 screw. Functional outcome 1 year postoperatively was rated as 15 excellent and 2 good, according to the Majeed functional scale. DiscussionIt is feasible and safe to stabilize the posterior pelvic ring disruption using iliosacral screw fixation under assistance of the 3D printed guide template. It could reduce fluoroscopy time, screw placement time and intraoperative blood loss and achieve good postoperative recovery. Level of proofIV; Retrospective study.

Radiographic outcomes of cortical screw fixation as an alternative to Kirschner wire fixation for temporary lateral column stabilization in displaced Lisfranc joint fracture-dislocations: a retrospective cohort analysis

BackgroundInjuries of the tarsometatarsal joint complex ranging from purely ligamentous to multidirectionally unstable midfoot fracture-dislocations are anatomically fixed to minimize long-term sequelae including post-traumatic arthritis, pes planus deformity, and chronic pain. Lateral column disruption is commonly treated with temporary Kirschner wire (K-wire) fixation, maintaining alignment during healing and allowing resumption of physiologic motion after hardware removal. More unstable fracture patterns may require temporary cortical screw fixation to maintain adequate reduction. We evaluated the efficacy of temporary lateral column screw fixation compared to K-wire fixation for Lisfranc fracture-dislocation treatment.MethodsThis retrospective cohort study reviewed 45 patients over fourteen years who underwent Lisfranc fracture-dislocation fixation at a level-one trauma center. All patients underwent medial and middle column fixation; 31 underwent lateral column fixation. Twenty six patients remained after excluding those without electronic records or follow-up. The primary outcome was radiographic lateral column healing before and after hardware removal; secondary outcomes included pain, ambulation, and return to normal shoe wear.ResultsTwenty patients were male, with mean age 41 years. Thirteen patients underwent cortical screw fixation and twelve K-wire fixation. One had both implants. Twenty four patients underwent lateral column hardware removal; all had radiographic evidence of bony healing before hardware removal. Mean follow-up was 88.2 ± 114 weeks for all patients. The cortical screw cohort had significantly longer mean time to hardware removal (p = 0.002). The K-wire cohort had significantly more disuse osteopenia (p = 0.045) and postoperative pain (p = 0.019).ConclusionsRadiographic and clinical outcomes of unstable Lisfranc fracture-dislocation treatment support temporary lateral column screw fixation as an alternate technique.Level of clinical evidence3 (retrospective cohort study)
