Risk of Volar Locking Plate Removal After Distal Radius Fractures: Time-to-Event Analysis.

PURPOSE: The primary purpose of this study was to describe the rate of volar locking plate (VLP) removal after distal radius fracture and how long it takes for the risk of VLP removal to stabilize. The secondary purpose was to describe the reasons for VLP removal and analyze the relationship between it and the Soong index. METHODS: This was a single-center retrospective cohort study. Patients aged >18 years with distal radius fracture who underwent VLP fixation were included. Hardware removal, time until VLP removal, and the primary reason for removal were recorded. The implant prominence was measured as described by Soong. We used Kaplan-Meier curves and risk tables to describe the risk of VLP removal and variation over time. Multivariable logistic regression was used to assess the relationship between Soong grade and VLP removal. RESULTS: A total of 313 wrists were included. There were 35 cases of VLP removal, with an overall incidence of 11.2% at 15 years of follow-up. The incidence rate was 1.2 per 100 individuals per year for the entire cohort. The risk of VLP removal decreased from 6.2% in the first postoperative year to 1.7% in the second year and 1.4% in the third year. Beyond that, the rate remained <1% per year throughout the follow-up period. The median hardware removal time was 11 months. The main reasons for VLP removal were tenosynovitis, implant-associated pain, and screw protrusion. We found no association between Soong grade and VLP removal. CONCLUSIONS: Volar locking plate removal after distal radius fracture was more common in the first year after surgery and remained notable until the third year. Regular monitoring and patient education to assess possible complications related to hardware are important during this period. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Glenohumeral Arthrodesis With Locking Compression Plate.

Glenohumeral arthrodesis is performed for paralytic disorders. Internal fixation with plates has been described to diminish the rate of nonunion associated with this procedure. Because plates are located over the scapular spine and the acromion to add a point of bony union between the acromion and the humeral head, skin irritation and hardware removal are the main complications associated with plates. We describe a technique using a locking compression plate placed under the acromion to decrease complications associated with the hardware without increasing the risk of nonunion. The technique presented here has 2 biomechanical principles of fixation: compression and neutralization. Compression by 2 screws allows for a bony union at the glenohumeral joint, and neutralization by the locking compression plate allows for early postoperative motion.

Comparative study of simple and complex open elbow dislocations.

BACKGROUND: Open elbow dislocations are rare injuries. Most of the evidence related to these dislocations is found in case reports or in series with closed injuries. We reviewed the experiences of three centers in the treatment of open elbow dislocations. QUESTION/PURPOSES: We compared the results after operative treatment of simple and complex open dislocations in terms of (1) ROM, (2) functional score, and (3) complications. METHODS: Eighteen patients were retrospectively included in this study: 11 with simple open elbow dislocations and seven with complex open elbow dislocations. Mean age was 40 years. Thirteen were men. Eight patients presented neurovascular injuries. Evaluation included ROM of the elbow and forearm as measured by hand-held goniometer. We then classified the results using the 100-point Broberg and Morrey functional rating index based on ROM, grip strength, elbow stability, and pain. Scores of 95 to 100 were considered excellent, 80 to 94 good, 60 to 79 fair, and less than 60 poor. Complications were recorded. Minimum followup was 6 months (mean, 25 months; range, 6-72 months). RESULTS: We found no differences between simple and complex open elbow dislocations related to ROM (median flexion/extension: 117° versus 110°, p = 0.12; forearm rotation: 160° versus 170°, p = 0.67). According to the Broberg and Morrey score, four patients had excellent results, five good, and one fair in the simple dislocation group, whereas in the complex dislocation group, four patients had excellent results, two good, and one fair (p = 0.8). No difference in complication rate was found between groups (p = 0.63). All complications in the simple dislocation group were neurovascular. In the complex dislocation group, there was one case of brachial artery occlusion, two cases of heterotopic ossification, one case of infection and nonunion, and one case of infection. No patients had recurrent elbow instability. CONCLUSIONS: No differences between simple and complex open elbow dislocations were found in terms of ROM, functional results, and rate of complications. Complications in the simple dislocation group were related to neurovascular injuries in contrast to the complex dislocation group where complications were associated with the bony injury. LEVEL OF EVIDENCE: Level IV, prognostic study. See Instructions for Authors for a complete description of levels of evidence.

The use of dynamic orthoses in the treatment of the stiff elbow.

The purpose of this study is to evaluate the outcomes of the treatment of stiff elbow with the use of dynamic orthoses. We included 30 patients with stiff elbow with an arc of mobility of 100° or less and a stable and congruent joint without heterotopic ossifications. The dynamic orthosis was designed in our service and consists of an articulated brace with springs. Mean previous mobility was 109°-41°, with an average arc of motion of 68°. Its use began 78 days after surgery or trauma and continued for 75 days. Statistical analysis was performed. Average follow-up was 23 months. Postoperative mobility was 126°-21° with an improvement of 37° of mobility. Ten patients did not recover a functional range of motion. Twenty-three patients were satisfied with the treatment and seven were unsatisfied with the use of the orthosis. Our results suggest that dynamic orthoses are useful in the treatment of stiff elbow. We achieved a mean improvement of 37° in the arc of motion, which in many cases has rendered arthrolysis unnecessary. The major strength of this paper is the practical application of the orthosis and its relatively easy manufacture.

The Foot as a Donor Site for Reconstruction in the Hand.

The foot contains a unique collection of tissue types that can be used in the reconstruction of the hand. Numerous reconstructive options have been presented, some of which have been adopted, such as modifications to procedures that have been described in the past or even newly developed options for hand reconstruction. It is possible to reconstruct missing fingers and other hand structures using tissues taken from the foot rather than removing healthy tissue from a hand that has already been injured. This makes it possible to avoid having healthy tissue removed from an injured hand.

Coverage of Palmar Mini Plates with Flexor Pulleys in the Treatment of Dorsal Fracture-Subluxation of the Proximal Interphalangeal Joint.

Introduction: Dorsal fracture dislocations (DFD) of the proximal interphalangeal joint (PIPJ) are challenging fractures. A palmar surgical approach and plate fixation has a high complication rate, including flexor contractions, reduction of range of motion (ROM) and secondary need for plate removal. Methods: We use the flexor tendon pulleys to cover the mini plate with the assumption that it may reduce the adhesion between the mini plates and the tendons and reduce postoperative complications. We present the outcomes of using this technique in eight patients. Results: All patients had an excellent outcome at a mean follow-up of 17 months, and none required removal of the implants. Conclusions: This study presents a surgical technique that may potentially reduce the high complication rate found after ORIF for treatment of DFD of the PIPJ. Therefore, improving the clinical outcomes after this type of surgery. Level of Evidence: Level IV (Therapeutic).

Fibula flap in upper extremity segmental/critical size bone defects fixed with locking plates. Single-institution observational cohort.

INTRODUCTION: Management of bone defects in the upper extremity can vary depending on the size and location of the defect. Large defects may require complex reconstruction techniques. Vascularized bone grafts, mainly free vascularized fibula flap (FVFF), have many advantages in the treatment of bone or osteocutaneous defects. However, complications such as graft fracture are the most common, with a free fibula flap for bone defects in the upper extremity. This study aimed to describe the results and complications associated with the treatment of posttraumatic bone defects in the upper extremity using FVFF. We hypothesized that performing osteosynthesis using locking plates would prevent or reduce the fracture of the fibula flap MATERIALS AND METHODS: This was a retrospective single-centre cohort study. Patients with segmental bone defects caused by trauma who underwent reconstructive surgery with FVFF fixed with locking compression plates (LCP) between January 2014 and 2022 were included. Demographic variables and preoperative data, such as bone defect, location, and time until reconstruction, were collected. Bone defects were classified according to the Testworth classification. Intraoperative variables included the length of the FVFF, type of graft (osteocutaneous or not), type and technique of arterial and venous sutures, number of veins used as output flow, and the osteosynthesis technique used. RESULTS: Ten patients were included (six humerus, three ulna, and one radius). All patients had critical-size bone defects, and nine patients had a history of infection. In 9 of 10 patients, bone fixation was performed with a bridge LCP and in one patient with two LCP plates. In eight cases, the FVFF was osteocutaneous. All the patients showed bone healing at the end of the follow-up period. There was one early complication, donor site wound dehiscence, and two long-term complications (proximal radioulnar synostosis and soft-tissue defect). CONCLUSION: A high rate of bone union with a low rate of complications can be obtained with an FVFF in upper extremity segmental/critical-size bone defects. Rigid fixation with locking plates avoids stress fractures of the grafts, mainly in humeral reconstruction. However, in these cases, a bridge plate should be used.

What Is the Infection Rate of Carpal Tunnel Syndrome and Trigger Finger Release Performed Under Wide-Awake Anesthesia?

BACKGROUND: High infection rates have been reported in hand procedures using the wide-awake local anesthesia no tourniquet (WALANT) method, causing some to question the validity of this approach. However, little evidence exists surrounding the direct use of WALANT compared with monitored anesthetic care (MAC). This study was conducted to directly compare the postoperative infection rates of carpal tunnel syndrome (CTS) and trigger finger (TF) release surgeries performed under WALANT and MAC. METHODS: A retrospective study comparing postoperative infection rates between patients undergoing CTS and TR releases was conducted. Our primary outcome measure was postoperative infection. Our secondary outcome was postoperative complications. Comparative statistics were used to compare means of infection between the groups. RESULTS: A total of 526 patients underwent CTS release (255 with WALANT and 271 with MAC), and 129 patients underwent TF release (64 with WALANT and 65 with MAC). Patients undergoing WALANT and MAC were statistically comparable in terms of sex, smoking status, diabetes, and American Society of Anesthesiologists physical status classification. In patients undergoing CTS release, there were no infections with WALANT and 6 infections (2.2%) with MAC. In patients undergoing TF release, there were no infections in either group. There were similar rates of complications in patients undergoing WALANT and MAC for CTS and TF releases. CONCLUSION: There was no increased risk of infection with WALANT compared with MAC in CTS or TR surgeries. These surgeries can be safely conducted with lidocaine and epinephrine without a concern for increased risk of infections or complications.

Does Age Affect the Outcomes of Core Decompression for the Treatment of Kienböck Disease?

Background: Core decompression of the distal radius is a minimally invasive technique that has demonstrated good clinical outcomes in the treatment of Kienböck disease. However, the effectiveness of core decompression has not been compared in different age groups. The aim of this study is to compare the outcomes of core decompression in patients <45 years of age to those ≥45 years of age. Methods: This retrospective study included 36 patients with Kienböck disease who were treated with core decompression over a 20-year period. The mean follow-up was 7 years. Outcome measures included visual analogue scale pain score (VAS), active range of flexion/extension at the wrist, grip strength, and modified Mayo wrist score. The patients were divided into two age groups namely <45 years (younger group; n = 22) and ≥45 years (older group; n = 12) and the outcome measures were compared between the two age groups. Results: There were no statistically significant differences between the outcomes of the two age groups. Conclusion: The outcomes of core decompression of the distal radius for Kienböck disease in older patients (≥45 years) are favorable and similar to those seen in younger patients (<45 years). Level of Evidence: Level III (Therapeutic).

Dorsal Plating for Specific Fracture Pattern of the Distal Radius.

Background: Volar locking plates have provided the capability to repair both simple and complex fractures. However, complications related to the inability to fix or to maintain the fixation of some fracture patterns have been reported with volar locking plates. The purpose of this study was to evaluate the results of dorsal plating treatment for specific pattern of fractures. Methods: Patients with distal radius fractures were retrospectively evaluated. Inclusion criteria for this study were those related to the patient and treatment (adult patients, internal fixation with dorsal plating, a minimum follow-up of 12 months), and those related to the fracture pattern (displaced central articular fragment, volar distal fracture line not enough to allow volar fixation, displaced dorsal-ulnar fragment, dorsal partial fractures, combination of these patterns). Clinical outcome information including active range of motion, radiographs, PRWE and DASH questionnaires were collected. Complications were recorded. Results: During a 6-year period, 679 distal radius fractures were treated with open reduction and internal fixation. Of these, 27 patients fulfilled the inclusion criteria. Patients were examined at a median of 34 months' follow-up. All but pronation, supination, and radial deviation had a statistically significant difference compared to the opposite side. The median score on the DASH was 4.5 and 3.2 on the PRWE. No patient suffered loss of reduction during the follow-up nor were tendon ruptures recorded. Conclusions: Although most of the distal radius fractures can be treated with volar locking plates, almost 5% of them present specific patterns that are amenable to treatment with dorsal fixation, without postoperative loss of reduction. These specific patterns are: (1) displaced central articular fragment, (2) volar distal fracture with less of 1cm distance from the distal volar edge of the radius, (3) displaced dorso-ulnar fragment, (4) Barton's fracture, (5) combination of these patterns.

A comparison of intercostal and partial ulnar nerve transfers in restoring elbow flexion following upper brachial plexus injury (C5-C6+/-C7).

PURPOSE: Restoring active elbow flexion is essential in the surgical management of C5-C6 +/- C7 brachial plexus palsies. This study compares the clinical results of 2 techniques to restore elbow flexion: the partial ulnar nerve transfer and the intercostal nerve transfer. METHODS: Partial ulnar nerve transfer was performed in 23 patients, and intercostal nerve transfer was performed in 17 patients. For both techniques, the transfer to the musculocutaneous nerve was made at the same anatomical point. Age and preoperative delay were comparable between groups of patients. RESULTS: Biceps reinnervation time was significantly earlier (p = .001) in the ulnar nerve technique (mean, 5.1 mo) than the intercostal nerve technique (mean 9.9 mo). Ten of 17 patients recovered useful elbow flexion force (British Medical Research Council grade >M3) in the intercostal nerve transfer group, compared with 20 of 23 patients in the ulnar nerve transfer group. No patient who had surgery more than 6 months after the injury recovered useful elbow flexion force in the intercostal nerve transfer. Elbow flexion strength was better in patients less than 30 years old in the intercostal nerve group. No complications were observed in either group. CONCLUSIONS: This study shows that transferring fascicles of the ulnar nerve yields better results than intercostals nerve transfer for restoring elbow flexion. Moreover, preoperative delay and age are important preoperative prognostic factors for the intercostal nerves transfers. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Comparative Study of Internal Fixation of the Ulna and Distal Ulna Resection in Patients Older Than 70 Years With Distal Radius and Distal Metaphyseal Ulna Fractures.

Background: Acute management of fractures of the distal ulna that are associated with fractures of the distal radius remains difficult, particularly in the elderly. Methods: In this study, we investigated whether internal fixation of the distal ulna is associated with a higher rate of complications than resection of the distal ulna in patients older than 70 years. Twenty-four consecutive patients were included in this study, 12 of whom had undergone open reduction and internal fixation (ORIF) of the distal ulna, and 12 who had undergone distal ulna resection. Patients were retrospectively assessed for range of motion, grip strength, pain, and radiographic appearance. The functional outcome was evaluated by the Mayo Wrist Score. Complications were classified according to the Classification of Surgical Complications. Results: There were no differences in patient demographics between the 2 groups, except patient age. Clinical evaluation showed no difference at follow-up; however, there were significantly more complications associated with ORIF compared with resection. Conclusions: The results from our study show that women older than 70 years with fracture of the distal radius and distal ulna have a higher rate of complications if ORIF of the distal ulna is performed. Patients should be warned, by surgeons, of this in cases where ORIF of the distal ulna is suggested.

Treatment of terrible triad injuries at a mean follow-up of nine years.

BACKGROUND: To evaluate the sustainability of the early clinical and radiological outcomes of terrible triad injuries at long-term follow-up. METHODS: Twelve consecutive patients who underwent fixation of terrible triad injuries with minimum of seven years of follow-up. Functional and radiological outcomes at one year and final follow-up were compared. We assessed Mayo Elbow Performance Score, Quick-Disability of the Arm Shoulder and Hand, and modified-American Shoulder and Elbow Surgeons Scores. Radiological evaluation included Broberg and Morrey classification and Hastings classification for heterotopic ossification. RESULTS: The mean age of patients was 55 years, with a median follow-up of 9.3 years. At final evaluation, mean flexion, extension, supination, and pronation were 145°, 6°, 82°, and 80°, respectively; mean Mayo Elbow Performance Score, modified-American Shoulder and Elbow Surgeons Scores, and Quick-Disability of the Arm Shoulder and Hand scores were, respectively, 97, 92, and 4.9 points. There was no statistical difference between early and final follow-up range of motion, Mayo Elbow Performance Score, and Quick-Disability of the Arm Shoulder and Hand. However, radiological changes were observed in 66% of the patients at final follow-up. Two patients underwent reoperation, with final satisfactory results. CONCLUSION: Our results suggested that using a standardized protocol, satisfactory clinical outcomes at early follow-up could be maintained over time. However, early complications and osteoarthritic changes at long-term follow-up can be expected. LEVEL OF EVIDENCE: Therapeutic IV Cases series.

Soft-Tissue Expansion beforeTotal Knee Arthroplasty:A Report of Two Cases.

INTRODUCTION: Wound complications are a feared complication following total knee arthroplasty (TKA). Furthermore, it is important to avoid underestimation in the pre-operative planning as it may lead to catastrophic TKA failure. Soft-tissue expansion (STE) has been indicated when insufficient or inadequate soft-tissue coverage is present before TKA as an alternative to optimize soft-tissue management. CASE REPORT: We report two cases in which we performed, previous to TKA, a prophylactic skin expansion around the knee. CONCLUSION: STE technique to expand the available tissue for closure and healing after TKA is a valuable tool in the treatment arsenal, which can be implemented by orthopedic surgeons.

Femoral Osteonecrosis after Medial Femoral Condyle Bone Graft Harvest.

The medial femoral condyle vascularized graft has become a useful resource in reconstructive microsurgery due to the rate of bony union, and the low rate of complication. We report osteonecrosis of the medial femoral condyle in a 65-year-old woman after harvesting a corticocancellous medial femoral condyle graft to treat a tarsometatarsal nonunion. We were not able to define whether a vascular or mechanical disorder could be the ultimate cause. However, because of the severity of the complication, we suggest informing patients who will undergo a medial femoral condyle flap about this infrequent complication.

Refractory actinomycosis of the humerus.

Actinomycosis is a chronic, opportunistic infection caused by Actinomyces species, such as Actinomyces bacillus. Actinomycosis in long bones is very rare. To the best of our knowledge, isolated primary actinomycosis of the humerus is rarely reported in literature. We present a rare case of a refractory primary actinomycosis of the humerus. A 66-year-old man with no history of concomitant conditions was admitted to our hospital with a history of a tumour on the distal third of the left arm as a result of a closed trauma without fracture 20 years before. Pathological anatomy samples showed the presence of Actinomyces. Cultures were subjected to a prolonged incubation of 21 days under aerobic and anaerobic conditions and were always negative. He underwent several surgical procedures and received long-term antibiotic therapy with poor outcome. Primary actinomycosis in long bones is uncommon. Diagnosis may be challenging: considering the small number of case studies reported in the literature, symptoms are not specific, and the organism is difficult to isolate. Antibiotic treatment may not be sufficient to improve the clinical condition, and surgical alternatives should be considered.
