RESUMEN

INTRODUCTION: The superficial location of the extensor tendons makes them particularly vulnerable to lacerations. Patients most commonly present to the emergency department (ED) after these injuries. We aimed to measure the safety of immediate surgical repair of traumatic open extensor tendon injuries in an ED minor procedure room (MPR) under local anesthesia, and the associated post-operative infection and complication rates. MATERIALS AND METHODS: We retrospectively evaluated all patients undergoing traumatic open extensor tendon repairs in the ED MPR over a 3.75-years period. Data collected included demographic information, comorbidities, mechanism of injury, additional procedures performed, and post-operative complications. All patients were operated under local anesthesia by a hand surgery fellow aided by an ED technician. RESULTS: Two hundred and forty eight patients (278 tendons) were treated for extensor tendon injuries during the study period. 220 patients (245 tendons) have complied with follow-up. No intra-procedural medical complications were encountered. The post-operative infection rate was 1.4%. The rate of other post-operative complications was not related to the number of tendons repaired, additional digit involvement, or if the nature of the injury was work-related. CONCLUSIONS: In this cohort, traumatic extensor tendon repairs performed in an ED MPR were found to be medically safe and to associate with a low postoperative infection rate. As preoperative assessment is simple and practical, and limited medical personnel is utilized, this surgical setting may enable us to reduce medical costs.

RESUMEN

BACKGROUND: Distal phalanx fractures are frequently encountered in our daily practice. They are often caused by crush injuries and are the most frequent work-related hand fractures. Different types of fixation have been proposed for displaced fractures. METHODS: A retrospective study was performed on two fixation types. Twenty-four distal phalanx fractures were treated with k-wire fixation with fluoroscopic control in a main operating room setting. Twenty-five distal phalanx fractures were treated with hypodermic needle fixation without fluoroscopic control in an emergency treatment room setting. Clinical and radiological data were collected on fracture type, fracture healing and complications. The cost of both types of surgery was assessed. RESULTS: No significant difference in healing time, union, delayed union and non-union was found between the two groups. Loosening was significantly more frequent in the hypodermic needle group, without affecting clinical or radiographic outcome. No infections were encountered in both groups. Surgery performed in the emergency treatment room reduced the cost with 9000 dollars when compared to surgery performed the main operating room. CONCLUSION: Treatment of displaced distal phalanx fractures with hypodermic needle fixation yields good results. Performing this procedure in a treatment room is safe and might reduce operative time, institutional costs and radiation exposure for both surgeon and patients.

RESUMEN

PURPOSE: The homodigital dorsolateral flap (HDF) was described to treat various types of pulp and fingertip defects. The aim of this study was to analyze the intermediate-term function after fingertip reconstruction with HDF and compare these results with the cross-finger flap. METHODS: We analyzed a retrospective cohort of 25 patients. The HDF group consisted of 16 patients (18 fingertip defects) with a mean age of 44 years (range, 16-63 y). The cross-finger flap group consisted of 9 patients (10 fingertip defects) with a mean age of 33 years (range, 16-47 y). The average follow-up time was 12 months (range, 6-36 mo). RESULTS: Patients with homodigital reconstruction demonstrated better sensibility in terms of mean static 2-point discrimination. Two-point discrimination was also better when the flap was advanced compared with when the flap was rotated. Mean distal interphalangeal joint range of motion for the HDF group was significantly better compared with the cross-finger flap group. Proximal interphalangeal joint range of motion was significantly better in the HDF group. CONCLUSIONS: The HDF for reconstruction of pulp defects is a reliable option for 1-stage reconstruction. Related complications are minimal, and the intermediate-term functional results are better compared with cross-finger flaps. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

RESUMEN

Transplantation of vascularized composite tissue is a relatively new field that is an amalgamation of experience in solid organ transplantation and reconstructive plastic and orthopedic surgery. What is novel about the immunobiology of VCA is the addition of tissues with unique immunologic characteristics such as skin and vascularized bone, and the nature of VCA grafts, with direct exposure to the environment, and external forces of trauma. VCAs are distinguished from solid organ transplants by the requirement of rigorous physical therapy for optimal outcomes and the fact that these procedures are not lifesaving in most cases. In this review, we will discuss the immunobiology of these systems and how the interplay can result in pathology unique to VCA as well as provide potential targets for therapy.

RESUMEN

We report our management of a 53-year-old female who suffered a wood planer hand-mutilating injury with significant dorsal soft tissue loss and partial metacarpophalangeal joint (MCPJ) amputations of the thumb, index, and middle fingers. The middle finger was deconstructed for "spare parts" and a vascularized osteochondral graft was utilized to reconstruct the metacarpal articular surface of the index finger proximal phalanx, allowing the pedicled transposition of the index finger to the third metacarpal. The middle finger's distal interphalangeal joint was transplanted non-vascularly to recreate the thumb MCPJ and the elevation of a middle finger fillet flap allowed dorsal wound coverage. The patient did well initially but required ulnar collateral ligament reconstruction with a palmaris longus tendon graft following MCPJ instability 10 months postoperatively. Nonetheless, she progressively regained thumb opposition and pinch grip and continues to have successful aesthetic and functional outcomes six years postoperatively, supporting the efficacy of non-vascularized joint transfers when vascularized options are superfluous or unavailable.

RESUMEN

PURPOSE: To evaluate the functional and radiographic results of a scaphoid excision and four-corner arthrodesis technique using percutaneous headless compression screws. METHODS: A cohort of 33 patients, mean age 51 (range, 20-72) years, was treated for scapholunate advanced collapse (19), scaphoid nonunion advanced collapse (12), midcarpal instability (1), and Preiser disease (1). After scaphoid excision and removal of cartilage and subchondral bone in the midcarpal joint through a limited arthrotomy, capitolunate fixation was achieved with a percutaneous, transmetacarpal Acutrak screw (Acumed LLC, Hillsboro, OR), and triquetrohamate fixation was done with a percutaneous screw. Scaphoid was used as a bone graft. The average follow-up time was 8 months (n = 32; range, 6-64 mo). RESULTS: Union occurred in 31 of 33 wrists (94%). One of the 33 patients had total wrist arthrodesis. Average total active flexion-extension arc was 71° after surgery and 83° before surgery. The postoperative carpal height averaged 0.47 compared to preoperative values of 0.45. The percentage of grip strength significantly improved from 41% before surgery to 80% after surgery. Postoperative mean verbal numerical rating scale pain score was less than 1, statistically better than the preoperative score of 7. Twenty-five of 33 patients were completely pain free. The average postoperative Mayo wrist score was 74, a significant improvement over the preoperative average of 40. Final Disabilities of the Arm, Shoulder, and Hand scores averaged 13 (n = 32; range, 0-49). CONCLUSIONS: These results were comparable to or better than the results of previously published techniques in terms of fusion rates, alleviation of pain, grip strength, range of motion; Mayo wrist score; and Disabilities of the Arm, Shoulder, and Hand questionnaire score. The technique exploits the theoretical advantages of strong compression between carpals while avoiding a screw-head sized hole in the lunate articular cartilage and preserving the dorsal capsular ligament attachments to the triquetrum.

RESUMEN

Arthrosis of the proximal pole of the hamate is a peculiar cause of ulnar-sided wrist pain. We present clinical, functional, and patient-reported outcomes of arthroscopic management. Methods: In this retrospective study, all patients with arthrosis of the proximal pole of the hamate encountered in a 10-year period treated with arthroscopy were reviewed. Patient demographics, arthroscopic details, associated injuries, and procedures were reviewed. Functional and patient-reported clinical outcomes after arthroscopic osteochondroplasty were analyzed. Results: An analysis of 39 patients who underwent arthroscopic osteochondroplasty showed a type II lunate prevalence of 87.2%. On wrist arthroscopy, a triangular fibrocartilaginous complex tear was the most common diagnosis (64.1%), followed by scapholunate ligament tear (61.5%) and lunotriquetral ligament tear (35.9%). All patients were managed arthroscopically with 100% procedural success. Average follow-up of 42.8 ± 37.7 months showed statistically significant improvements in the visual analog score and Mayo wrist score postoperatively (P < 0.01). Three patients (7.7%) failed the procedure at a mean of 23 ± 31.4 months. Risk factors for salvage operations were nondominant wrist involvement 100% (P = 0.04), lunotriquetral ligament injury 100% (P = 0.04), the absence of triangular fibrocartilaginous complex injury 100% (P = 0.04), and the presence of scapholunate advanced collapse 100% (P < 0.01). Conclusions: Wrist arthroscopy is valuable for accurately diagnosing and treating hamate arthrosis and identifying a wide variety of pathologies associated. This study showed arthroscopic osteochondroplasty produced satisfactory clinical results. Furthermore, the presence of scapholunate advanced collapse wrist offers its prognostic value in determining treatment failure.

RESUMEN

Introduction Schwannomas represent benign peripheral nerve sheath tumors. Their phenotypic presentations in schwannomatosis and segmental schwannomatosis have been well described. To date, however, cases of schwannomatosis or multiple schwannomas localized to a single nerve fascicle have been limited in the literature. Case Presentation In this study, we identify a case of a 48 year-old non-neurofibromatosis male who presented with symptomatic schwannomas localized to a single nerve fascicle of the upper extremity. Intraoperative exploration revealed four schwannomas arising from a 15-cm segment of ulnar nerve fascicle. Surgical excision was successful, without neurological deficit or recurrence. Conclusion This study identifies a case of schwannomatosis localized to a single nerve fascicle that may represent a linear variant of segmental schwannomatosis. The presentation may represent a temporary linear appearance in progression to "nonlinear" segmental variant; however, a molecularly distinct subset of schwannomas cannot be excluded.

RESUMEN

Barber's disease is an occupational-related disease in which small hair fragments penetrate the dermis of the hand. Although there is limited literature related to the topic, barber's disease classically involves the interdigital space of hairdressers' hands. In this case report, we report an undescribed variation of the condition. The case involves a female hair stylist who presented to the office with numerous hair splinters under the nail plate of her dominant thumb. Subsequent evaluation revealed cystic destruction of the distal phalanx of the thumb. Despite preoperative suspicion for osteomyelitis, pathology revealed reactive bone fragments associated with surrounding tenosynovial tissue and no evidence of osteomyelitis. The proposed etiology of this finding is the inflammatory process related to a hair abscess that formed with a sinus originating in the lateral nail fold. The goal of the case report is to bring to light yet another variation of barber's disease.

RESUMEN

OBJECTIVES: This study aims to evaluate the clinical and radiological outcomes of diamond-shaped Kirschner (K)-wire fixation for the treatment of acute perilunate dislocation (PLD) or trans-scaphoid perilunate fracture dislocation (PLFD). PATIENTS AND METHODS: We performed a retrospective review of 18 patients (18 wrists; 17 males, 1 female; mean age 31.5±2.6 years; range, 18 to 47 years) treated for PLD/PLFD using a dorsal approach with the diamond-shaped K-wire fixation between November 2001 and September 2017. The mean follow-up of cohort was 27 (range, 13 to 74) months. Using a dorsal approach, open ligament repair and bone fixations were performed. Perilunate dislocation was reduced and the carpal bones and midcarpal joint were held in anatomical position using four K-wires transfixing the scapholunate (SL), lunotriquetral, scaphocapitate, and triquetrohamate joints in such a shape that each bone received two K-wires. RESULTS: The mean range of motion and grip strength measured using a Jamar® dynamometer of the injured wrist compared to the uninjured extremity were 84.3% and 78.8%, respectively. The mean Mayo wrist score was 78.3 (range, 70 to 90). The mean Visual Analog Scale score was 1.2 (range, 0 to 4). The average SL gap at the final follow-up evaluation was 1.62 (range, 1 to 2.3) mm. The mean SL and capitolunate angles were 49.3° (range, 40 to 75°) and 4.2° (range, 2 to 12°), respectively. CONCLUSION: Because every bone is fixed with two K-wires using this configuration, a closed ring is created; hence no motion is possible between the scaphoid, capitate, hamate, triquetrum, lunate and the midcarpal joint. We believe that diamond-shaped fixation may provide reliable fixation and satisfactory clinical outcomes in patients with PLD and PLFD.

RESUMEN

Contracture as well as weakness of the flexor hallucis longus (FHL) are possible complications following free fibula flap harvest. Possible causes have been related to fibrotic change of the muscle either due to devascularization or compartment-like syndrome after a tight wound closure. This study elucidates the vascularization and nerve supply of the FHL muscle after fibula flap harvest in a fresh cadaver model.A fibula bone flap was harvested through a lateral approach in 20 fresh limbs. The popliteal artery was isolated and injected with a silicone compound, the muscle isolated, and its neurovascular supply visualized.The distal third and fourth portion of the FHL muscle was always found to be located in a more compressed and deeper compartment. The peroneal artery was entirely filled by the silicone compound in 17 fresh cadaver limbs with at least one branch supplying the distal fourth of the FHL. The posterior tibialis artery was filled in all limbs and an average of 2 branches was found to supply the muscle. In all dissections, the nerve supplying the FHL originated from the tibialis nerve with an average of three branches perforating the muscle.Following fibula harvest, the FHL muscle will maintain vascular supply through the distal portion of the peroneal artery and the posterior tibialis artery. Nerve injury to the FHL muscle is unlikely during flap harvest.

RESUMEN

A 17-year-old boy who played baseball presented with swelling, pain, and crepitation in the right ring finger proximal interphalangeal joint after a remote trauma. Multiple osteochondral defects were identified on opposing articular surfaces. Cylindrical osteochondral grafts of 2.0, 2.5, and 5.0 mm were applied to the defects and congruency was restored. We confirmed vascularity of the grafts by magnetic resonance. The boy returned to full sports activities. No signs of arthritis were seen at 4-year follow-up radiographs.

RESUMEN

Purpose: To evaluate the recurrence of symptoms after an endoscopic cubital tunnel release using the technique of Hoffmann and Siemionow. Methods: We retrospectively reviewed 286 consecutive patients who underwent Hoffmann and Siemionow's technique of endoscopic cubital release by a single surgeon during an 8-year period. Inclusion criteria were adult patients without previous elbow surgery, pathology, or trauma, and patients with a minimum 3-months' postoperative follow-up. We evaluated symptom recurrence rate and assessed risk factors that would affect recurrence. Results: A total of 223 patients met inclusion criteria, 204 of whom (91.5%) had improvement at 3 months after surgery. Eleven patients (4.9%) had persistent symptoms and 8 (3.6%) had recurrent symptoms at a mean of 16 months (range, 3-93 months) after the primary surgery. Intraoperative ulnar nerve subluxation had a statistically significant relationship with symptom recurrence. Conclusions: Symptoms recurred at a rate of 3.6% after Hoffmann and Siemionow's endoscopic cubital tunnel release. This is comparable to other endoscopic or open techniques for cubital tunnel release. The procedure has the added advantage of less tissue dissection. Intraoperative ulnar nerve subluxation seems to be associated with symptom recurrence. Type of study/level of evidence: Therapeutic IV.

RESUMEN

PURPOSE: To compare the short-term outcomes between arthroscopic and open procedures for the treatment of lateral epicondylitis. Because a significant portion of patients have worker's compensation (WC), the outcomes in these subgroups were separately analyzed. METHODS: A retrospective analysis of patients who had surgical treatment of lateral epicondylitis by a single surgeon from 2010 to 2017 was performed. Patients who were symptomatic after 9 months of conservative treatments including nonsteroidal medications, steroid injections, and physical therapy were offered surgical intervention. The type of surgery was selected after detailed consultation with the patient. Charts were reviewed for preoperative pain, grip strength as measured by dynamometer, smoking status, and WC status. Postoperative assessments included pain and grip strength at 6 weeks and time taken to return to full duty. Two groups were compared using unpaired t test and chi-squared tests. Results were compared with similar studies in the literature. RESULTS: The study included 30 patients in the arthroscopic debridement group and 42 patients in the open tenotomy and reinsertion group. Eighteen patients (25%) had WC. Compared with the open group, the arthroscopic group had earlier return to full duty (mean 7.13 weeks, confidence interval [CI] 6.21 to 8.05 versu mean of 12.22 weeks, CI 11.21 to 13.24; P < .001) and less time for complete pain relief (mean 7.4 weeks, CI 7.02 to 7.93 versus 9.5 , CI 8.68 to 10.44; P = .043). No difference was seen among the groups in terms of unfavorable outcome (persistent pain and recurrence of pain), JAMAR hand dynamometer score at 6 weeks, and visual analog score at 6 weeks. A total of 11 patients (15%) had unfavorable outcome. Incidence of unfavorable outcomes was more in patients with WC insurance (36% in WC versus 7% in non-WC; P = .023). No association was seen with smoking status. WC patients also had a longer time to return to full duty (16.68 weeks for WC versus 7.65 weeks for non-WC; P < .001) and a longer time to get complete pain relief (12.4 weeks for WC versus 7.5 weeks for non-WC; P < .001). CONCLUSION: The arthroscopic technique offers advantages of earlier return to work and shorter recovery period along with additional advantages of joint inspection and ability to treat coexisting pathologies. WC patients had a longer time to return to full duty and time for complete pain relief. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

RESUMEN

Sagittal band injuries may result in extensor digitorum communis (EDC) tendon instability and may require operative treatment for symptomatic loss of extension, pain, and snapping at the metacarpophalangeal joint (MCPJ). Operative methods vary according to the source of donor tissue, as well as the anchor point of attachment. We present a surgical technique that diminishes tension of the repair with MCPJ flexion. Twenty-two EDC tendon stabilization procedures were performed between 2006 and 2017 using a tendon flap method. The selection criteria for this group of patients included completely dislocating extensor tendons with persistent complaints of pain and decrease in finger extension despite at least a 6-week conservative treatment attempt. All subjects underwent surgical treatment for tendon centralization using a distally based tendinous flap from the EDC sutured to the adjacent finger volar plate. A mathematical model was developed to analyze repair tension at 30, 60, and 90 degrees of MCPJ flexion calculating the flap length difference of 2 attachment points: deep transverse metacarpal ligament versus adjacent volar plate. Centralization was maintained in all digits with no evidence of subluxation at final postoperative evaluation. Clinical symptoms of pain and weakness resolved in all patients. Mathematical modeling provided evidence that translation of the anchor point of reconstructed flap to the volar plate of the adjacent finger resulted in lower tensile forces when compared with attachment at the intermetacarpal ligament. This optimized forces on reconstructed tendon flap experienced during MCPJ flexion.Level of Evidence: Level IV-therapeutic, case series.

RESUMEN

Background: A few arthroscopic options have been proposed for the treatment of early stages of the arthritis of the thumb carpometacarpal (CMC) joint. The purpose of this study was to compare the results of arthroscopic abrasion arthroplasty with ligament reconstruction and tendon interposition (LRTI). Methods: In this retrospective cohort study, 11 patients who underwent thumb CMC joint arthroscopic abrasion arthroplasty were compared with 15 patients who were randomly selected from a group of 80 LRTI arthroplasty patients during the same study period, with a minimum 1 year follow-up. Preoperative and postoperative evaluations included radiographs and measurements of grip strength, visual analog scale (VAS) pain scores, and Disabilities of the Arm, Shoulder and Hand (DASH) scores. Results: The mean preoperative VAS score in both groups was 6.8. Mean preoperative DASH scores were 61.1 in the arthroscopy group and 67.4 in the LRTI group. Postoperative VAS score at final follow-up was 4.8 in the arthroscopy group and 1.2 in the LRTI group (P < .05). Postoperative DASH scores 9 months after surgery were 23 for the LRTI group and 55.2 for the arthroscopy group (P < .05). Eight patients in the arthroscopy group had a second surgery due to persistent pain. Conclusions: Patients undergoing arthroscopic abrasion arthroplasty had high revision rates, higher postoperative pain, and lower patient-rated outcomes than patients undergoing LRTI procedure. The poor results in the arthroscopy group may be secondary to the inherent instability of the CMC joint and lack of use of any biological or artificial interposition material.

RESUMEN

Vascularized composite allotransplantation (VCA) has emerged as the most recent field of transplantation to offer an alternative treatment for those patients that have failed or are not suitable candidates for conventional therapy. Most of the current clinical experience in this field is with recipients of skin containing grafts such as the face, upper extremity and abdominal wall transplants. Like solid organ recipients, VCA recipients require lifelong systematic immunosuppression to maintain their grafts. To date, the most successful immunosuppressant regimens are calcineurin inhibitor based and have been targeted to the control of T cells. While these regimens have resulted in excellent short term graft survival in solid organ transplantation, achieving significant improvements in long term survival has been more challenging. The reasons are multi-factorial, but a role for B cells and humoral immunity has been proposed. Antibody mediated rejection leading to chronic rejection has been cited as the leading cause of renal graft loss. While the number of VCA transplants performed is still small, evidence to date suggests that antibody mediated rejection may occur less frequently than seen in solid organ transplants. Here we will discuss the role of B cell immunity in solid organ transplantation as it pertains and contrasts to the field of VCA and present some examples of possible sequela of B cell immunity in a series of hand transplant recipients.

RESUMEN

OBJECTIVES: The goal of this study was to define the parameters of movement of indocyanine green in the upper extremity of normal control and hand transplant recipients. The purpose was to establish a non-invasive method of determining the level of lymphatic function in hand transplant recipients. In hand transplantation (and replantation), the deep lymphatic vessels are rarely repaired, resulting in altered lymphatic connections. In most cases, the relatively rapid inosculation of superficial lymphatic networks and drainage via the venous systems results in sufficient interstitial fluid and lymph drainage of the graft to prevent edema. However, our group and others have determined that some transplant recipients demonstrate chronic edema which is associated with lymphatic stasis. In one case, a patient with chronic edema has developed chronic rejection characterized by thinning of the skin, loss of adnexal structures, and fibrosis and contracture of the hand. METHODS: Lymphatic function was evaluated by intradermal administration of near-infrared fluorescent dye, indocyanine green, and dynamic imaging with an infrared camera system (LUNA). To date, the assessment of lymphatic drainage in the upper extremity by clearance of indocyanine green dye has been studied primarily in oncology patients with abnormal lymphatic function, making assessment of normal drainage problematic. To establish normal parameters, indocyanine green lymphatic clearance functional tests were performed in a series of normal controls, and subsequently compared with indocyanine green clearance in hand transplant recipients. RESULTS: The results demonstrate varied patterns of lymphatic drainage in the hand transplant patients that partially mimic normal hand lymphatic drainage, but also share characteristics of lymphedema patients defined in other studies. The study revealed significant deceleration of the dye drainage in the allograft of a patient with suspected chronic rejection and edema of the graft. Analysis of other hand transplant recipients revealed differing levels of dye deceleration, often localized at the level of surgical anastomosis. CONCLUSION: These studies suggest intradermal injection of indocyanine green and near-infrared imaging may be a useful clinical tool to assess adequacy of lymphatic function in hand transplant recipients.

RESUMEN

The field of vascularized composite allotransplantation (VCA) has moved from a highly experimental procedure to, at least for some patients, one of the best treatment alternatives for catastrophic tissue loss or dysfunction. Although the worldwide experience is still limited, progress has been made in translation to the clinic, and hand transplantation was recently designated standard of care and is now covered in full by the British Health System. This progress is tempered by the long-term challenges of systemic immunosuppression, and the rapidly evolving indications for VCA such as urogenital transplantation. This update will cover the state of and recent changes in the field, and an update of the Louisville VCA program as our initial recipient, the first person to receive a hand transplant in the United States celebrates the 20th anniversary of his transplant. The achievements and complications encountered over the last two decades will be reviewed. In addition, potential directions for research and collaboration as well as practical issues of how third party payers and funding are affecting growth of the field are presented.
