Volar Capsulodesis With Early Active Motion for the Treatment of Chronic Proximal Interphalangeal Joint Hyperextension Deformity.

PURPOSE: We evaluated the clinical outcomes of a series of patients with hyperextension deformity of the proximal interphalangeal joint treated with volar capsulodesis. METHODS: This retrospective study included 16 patients with symptomatic locking of the proximal interphalangeal joint who underwent volar capsulodesis and were followed for at least 2 years. We excluded patients with severe, degenerative changes on plain radiographs. Clinical evaluation included the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire; Catalano's scale for proximal interphalangeal joint hyperextension deformity correction; a visual analog scale for pain; range of motion; and grip strength. Hyperextension recurrence and residual flexion contracture were also recorded. RESULTS: There were 2 women and 14 men, with a mean age of 36 years (range, 22-60 years). The mean preoperative pain scores according to the visual analog scale were 3.6 (range,1-8) and 0.5 (range, 0-3) at the final follow-up. No patient had a recurrence of the hyperextension deformity. The average Quick Disabilities of the Arm, Shoulder, and Hand score was 5, and the mean grip strength was 87% of the contralateral side. Five patients were rated as having excellent results, 9 patients as having good results, and 2 patients as having fair results. Residual flexion contracture was less than 10° in 13 patients and more than 10° in 3 cases. All patients returned to unrestricted activities. CONCLUSION: Volar capsulodesis with early active motion demonstrated favorable results and could be considered as a surgical option for the treatment of chronic hyperextension deformity of the proximal interphalangeal joint.

Time until union in absolute vs. relative stability MIPO plating in simple humeral shaft fractures.

PURPOSE: The objective of this study is to evaluate the effect of absolute stability (AS) versus relative stability (RS) performed through a minimally invasive plate osteosynthesis (MIPO) in AO/OTA 12A1 and 12A2 fractures on healing and the time to radiographic union. METHODS: This was a retrospective cohort study of all patients treated with plate fixation for AO/OTA type 12A1-A2 fractures at a single institution. Patients were grouped according to the type of stability used in their surgery. Time until radiographic union was estimated using the Kaplan-Meier method, which was compared by long-rank test between both types of surgical techniques. RESULTS: A total of 70 patients were included in this study with 35 patients in each group. The median follow-up was 9 (IQR 6-14) months. The median time to radiographic union was significantly lower in the AS group than in the RS group: 12 (interquartile range (IQR) 10-14) weeks versus 18 (IQR 16-19) weeks, respectively (p < 0.001). Non-union was seen in two cases (7%) in the relative stability group. Three patients in the RS group developed a post-operative radial nerve palsy. CONCLUSION: The main finding of this study is that the median time to radiographic union was significantly shorter in the patients treated with AS compared to those with a RS technique. These findings support the recommendations of the AO foundation in that simple metaphyseal fractures (type A) that require surgical treatment should be treated with an AS construct. RS techniques should be reserved to multifragmentary fractures where fragment preservation of blood supply is paramount.

Metacarpal Aneurysmal Bone Cyst En Bloc Resection Reconstructed With Osteoarticular Allograft.

Aneurysmal bone cysts are large lytic lesions that appear most often around metaphyseal bone. The lesions are locally aggressive with high recurrence rates. Therefore, wide resection is commonly necessary, leading to challenging reconstruction of the defect, especially when the articular surface is involved. We present a case of an aneurysmal bone cyst of the fourth metacarpal, treated with an en bloc resection and reconstruction with a metacarpal osteoarticular allograft. At 8 years after surgery, the patient has shown no signs of recurrence, but radiographic articular reabsorption was noted. However, the patient showed an excellent outcome with a satisfactory active range of motion and grip strength. Despite potential complications, osteoarticular allograft is a feasible alternative when autologous osteoarticular reconstruction is not an option.

Innervation of the Proximal Interphalangeal Joint: An Anatomical Study.

PURPOSE: To describe the innervation of the proximal interphalangeal (PIP) joint of the fingers as well as the anatomical relations of the articular branches. METHODS: In this anatomical study, 52 fresh-frozen index, long, ring, and little fingers of 6 male and 4 female cadavers were dissected after injection of a colored latex composite. The anatomical dissections were performed under ×3.5 and ×6.0 magnifications. The numbers of articular nerve branches that penetrated the PIP joint on both sides of the fingers were quantified and patterns of innervation were established. We also measured the origin of the branches regarding the PIP articular line, the angle of emergence, and the diameter of the nerves. RESULTS: The PIP joint was innervated by one articular branch of the proper palmar digital nerve at each side of the finger (pattern 1). Less frequently, an additional distal branch from the same proper palmar digital nerve was found (pattern 2). Dorsal articular branches were identified innervating only the little finger. CONCLUSIONS: The findings suggest that PIP joints of the fingers have a consistent articular nerve anatomy predominantly provided at the palmar aspect of the joint. These findings provide an anatomical basis for procedures to denervate the PIP joint. CLINICAL RELEVANCE: An accurate understanding of peripheral nerve anatomy of the PIP joint is essential to improve outcomes in denervation techniques.

Vascularized Distal Radius Bone Graft for Treatment of Ulnar Nonunion.

Various methods have been reported to treat forearm nonunions with good results. However, in the presence of infection, inadequate vascularity of surrounding tissues, or failed prior grafts, vascularized bone grafts are a valid alternative. We describe the surgical technique to obtain distal radius vascularized bone graft pedicled on the radial artery (RA) and its clinical application in 1 case of an ulnar nonunion. We studied the surgical technique in 12 freshly injected cadavers. In the distal forearm, the RA provides several periosteal branches to supply the distal radius metaphysis. These vessels are located between the distal insertion of the brachioradialis and the deep surface of the radial half of the pronator quadratus. A 6-cm vascularized bone graft can be harvested from the radius, and dissection of the RA enables a long pedicle with a wide arc of rotation readily able to reach the proximal part of the ulna. The present technique is a reproducible alternative that allows the treatment of bone defects up to 6 cm, without the potential technical difficulties of a free bone flap.

Midterm Outcomes After Arthroscopic Anteroinferior Capsular Release for the Treatment of Idiophatic Adhesive Capsulitis.

PURPOSE: The purpose of this study is to report the early and midterm functional outcomes and complications of a consecutive series of patients with primary adhesive capsulitis who were treated with isolated anteroinferior arthroscopic capsular release after they did not respond to conservative treatment. METHODS: Thirty-two consecutive patients with idiopathic adhesive capsulitis who did not respond to conservative physiotherapy were included in the study. Arthroscopic anteroinferior capsular release was performed in all cases. The primary outcome was improvement in range of motion in the short- and midterm follow-up. We also evaluated pain relief with the visual analog scale, functional outcomes with the Constant-Murley score, and we registered postoperative complications. RESULTS: The mean age was 49.6 years (range, 33-68 years) and the mean follow-up was 63 months (range, 18-84). Overall, there was significant improvement in the Constant-Murley score from 42.4 to 86 points (P < .001). The visual analog scale decreased by approximately 6.3 points compared with the preoperative value (P < .001). All parameters improved significantly the first 6 months and then remained stable until the end of follow-up (P < .001). There was an additional minor improvement in both parameters between the sixth month and the final follow-up; however, this improvement was less than in the first 6 months and it was not statistically significant. CONCLUSIONS: In patients who don't respond to conservative treatment for primary adhesive capsulitis, isolated anteroinferior capsular release provides a reliable improvement in pain and range of motion that is maintained in the mid-term follow-up. LEVEL OF EVIDENCE: Level IV, therapeutic, case series study.

Extended Posterior Interosseous Artery Flap: Anatomical and Clinical Study.

PURPOSE: A reverse-flow pedicled flap from the posterior interosseous artery (PIA) has been used to cover defects on the dorsal and volar aspects of the hand. However, the original description of this flap does not reach further than the metacarpophalangeal joints of the 4 ulnar digits. In the present study, we describe a distal variant (type 2) of the PIA flap, which changes the pivot point of the classic variant (type 1) and which can provide full coverage of single or multiple digits in the entire dorsum and palmar surface of the fingers. METHODS: An anatomical study was performed on 26 cadaveric specimens to assess the presence of the anastomosis between the PIA and the dorsal intercarpal arch (DIA). In addition, the gain in pedicle length using the DIA anastomosis as a pivot point was compared with the classic pivot point at the anterior interosseous artery. A clinical study in 19 patients with soft tissue defects distal to the proximal interphalangeal joint of the fingers was also performed to assess the viability and clinical outcomes of the new variant of the PIA flap. RESULTS: The PIA was identified reaching the dorsal carpal arch in all anatomical specimens. The mean pedicle length of the fifth extensor compartment artery was 4.8 cm (range, 4.1-5.3 cm). The mean arterial diameter was 0.8 mm (range, 0.6-1.2 mm). In the clinical study, 17 flap reconstructions were done for posttraumatic lesions and 2 postburn contractures. All extended PIA flap procedures were performed successfully without loss of the flap or significant partial necrosis. We had only 1 superficial infection. There was no need for revision of the flap in any case. CONCLUSIONS: By extending the pivot point of the PIA flap through the DIA, instead of the anastomosis with the anterior interosseous artery, the flap distance can be increased by about 8.5 cm, allowing complete coverage of the fingers. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Radius Core Decompression for Kienböck Disease Stage IIIA: Outcomes at 13 Years Follow-Up.

PURPOSE: This study was designed to analyze the long-term clinical and radiological outcomes of a series of patients with Kienböck disease stage IIIA treated with radius core decompression. METHODS: This retrospective study included 15 patients with Kienböck disease (Lichtman stage IIIA) who underwent distal radius metaphyseal core decompression between 1998 and 2005 and who were followed-up for at least 10 years. At the last follow-up, the patients were evaluated for wrist range of motion and grip strength. The overall results were evaluated by the modified Mayo wrist score and visual analog scale pain score. We also compared the radiological changes between the preoperative and the final follow-up in their Lichtman classification and the modified carpal height ratio. RESULTS: The mean follow-up period was 13 years (range, 10-18 years). Based on the modified Mayo wrist score, clinical results were excellent in 6 patients, good in 8 patients, and poor in 1 patient who required a proximal row carpectomy as revision surgery. The mean preoperative pain according to the visual analog scale was 7 (range, 6-10) and was 1.2 (range, 0-6) at the final follow-up. Compared with the opposite side, the average flexion/extension arc was 77% and the grip strength was 80%. All patients, except 1, returned to their original employment. At the final follow-up, 3 patients had decreased modified carpal height ratio, 12 remained unchanged. Radiographic disease progression according to the Lichtman classification to stages IIIB to IV occurred in only 2 wrists. There were no complications related to the core decompression. CONCLUSIONS: In this limited series, the radius core decompression demonstrated favorable long-term results and could be considered as a surgical alternative for stage IIIA of Kienböck disease. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Assessment, Diagnosis and Management Strategies for Forearm Shaft Non-union: A Contemporary Perspective.

Forearm non-union poses a challenge in orthopaedic surgery due to its intricate anatomy and functional significance. This review provides a comprehensive overview of the assessment, diagnosis and management of forearm non-union. Initial evaluation involves a meticulous history, physical examination and imaging studies to identify factors contributing to non-union, including infection. Surgical approaches are discussed, with emphasis on restoring biomechanical stability and promoting bone healing. Treatment options range from autografts to allografts, with considerations for vascularised bone transfers in complex cases. Decision-making strategies are outlined, considering patient-specific factors and individualised treatment plans. Special considerations for specific types of forearm non-unions are addressed, along with postoperative care protocols to optimise healing and functional outcomes. Overall, this review aims to provide clinicians with a comprehensive understanding of forearm non-union management based on current evidence and clinical practice. Level of Evidence: Level V (Therapeutic).

The "Bubble Test" in the Arthroscopic Diagnosis of Triangular Fibrocartilage Central Lesion: Description and Relevance to Treatment.

Background Ulnarly sided wrist pain is a common and challenging symptom. Arthroscopy has become a safe and effective tool for the correct diagnosis and treatment, proving to be better than all other clinical and imaging diagnostic methods. Some tests have been described for the diagnosis of triangular fibrocartilage (TFC) lesions, such as the trampoline test for peripheral lesions and the hook, ghost, and suction tests for foveal detachments. In tears at the disc level, when they affect all layers of the TFC (complete lesion) at the same point, testing with the probe will usually suffice for the diagnosis. However, in some apparently partial lesions, the probe cannot pass through all layers because the proximal and distal sites of the lesion are not aligned. There has been no arthroscopic test described for such cases. Case Description We describe a simple and practical test that we have called the "bubble test" in a typical case to diagnose TFC central injuries, aiming to discriminate partial from complete lesions, which are eventually hard to differentiate through direct vision and arthroscopic probing, leading to a direct influence onto the treatment. The bubble test is performed with external compression of the distal radioulnar joint (DRUJ) aspect, with the thumb on the back of the DRUJ and the index and middle fingers onto the volar aspect. The abrupt compression of this region causes the passage of air mixed with synovial fluid from the DRUJ to the radiocarpal joint, generating bubble formation. Clinical Relevance The bubble test should correlate to physical examination and imaging (magnetic resonance imaging [MRI]) findings and is particularly useful in central and degenerative (Type II) TFC lesions in patients complaining of chronic pain on the ulnar region of the wrist, with no history of trauma and with inconclusive MRI findings. Once the diagnosis is confirmed, arthroscopic treatment consists of wide debridement of the lesion with resection of the injured tissue and the local inflammatory reaction. Thus, it is essential for the correct treatment to define the exact location of the lesion and to know whether the disc injury is complete.

Is There a Correlation between the Radiological and Clinical Outcome after Core Decompression of the Radius for Kienböck Disease?

Background: Despite the good clinical results in the treatment of Kienböck disease with distal radius core decompression, a radiological progression to a certain degree in the long-term follow-up is possible. Is there a negative correlation between the clinical improvement of the patients and the radiological progression? Methods: We retrospectively reviewed the radiological and clinical results of 24 patients (mean age: 38 years; 10 women) treated with core decompression for Kienböck disease. The mean follow-up was 10 years. Results: A radiologic progression in the Lichtman classification was seen in nine patients. The Spearman correlation did not show any correlation between this radiological progression and the clinical outcome. Namely -0.06 between Mayo and Lichtman classification and 0.16 between VAS and Lichtman classification. Conclusions: We found that the clinical outcomes do not deteriorate despite a radiological progression of patients treated with core decompression for Kienböck disease Level of Evidence: Level IV (Therapeutic).

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).

Unicortical versus bicortical plate fixation for midshaft clavicular fractures.

BACKGROUND: The aim of this study was to compare the functional and radiological outcomes of unicortical vs bicortical fixation in patients with midshaft clavicular fractures who were treated using pre-contoured locking plates. METHODS: We performed a prospective multicenter study of 45 individuals who underwent open reduction and internal fixation of midshaft clavicular fractures with precontoured locking plates between March 2017 and December 2019. Twenty-five patients were treated with bicortical screws and 20 patients with unicortical screws. Functional outcomes were assessed at 6 months and 12 months after surgery using the Constant score, the 11-item version of the Disabilities of Arm, Shoulder and Hand (Quick- DASH) score and the Single Assessment Numeric Evaluation (SANE) score. Pain was evaluated using a visual analog scale (VAS). The rate of return to work and sports was also recorded. Radiologic evaluation was obtained in the immediate postoperative day, monthly until fracture consolidation, at 6 months and 12 months. All intraoperative and postoperative complications were documented. RESULTS: At both 6 and 12 months, the follow-up rates were 100%, and the mean age was 28.5 years (range, 20 to 45 years). The mean postoperative Constant score, Quick DASH, and SANE score at 12 months were 93.5 (±6), 2.3 (±3), and 92% (±7), respectively. There were no significant differences in the functional scores between the groups neither at 6 months nor at 12 months. Of the 30 active workers, 97% were able to return to their previous working routine and from the 25 patients who practiced sports before the injury,92% returned to sports all at the same level. All the fractures healed in both groups. There were 6 complications (13%). CONCLUSION: In young, active patients with displaced midshaft clavicular fractures, both unicortical and bicortical locked plates achieved 100% bone consolidation, with excellent functional outcomes and a low rate of complications without significant differences between the groups. Therefore, locked plates with unicortical fixation could be a very good alternative for the management of young patients with midshaft clavicular fractures, potentially avoiding severe neurovascular complications. LEVEL OF EVIDENCE: Prospective comparative (Level II).

The anatomy of the anconeus nerve redefined.

The anconeus nerve is the longest branch of the radial nerve and suitable as a donor for the neurotization of the axillary nerve. The aim of this study was to map its topographical course with reference to palpable, anatomical landmarks. The anconeus nerve was followed in 15 cadaveric specimens from its origin to its entry to the anconeus. It runs between the lateral and the medial head of the triceps before entering the medial head and running intramuscularly further distal. Exiting the muscle, it lies on the periosteum and the articular capsule of the elbow, before entering the anconeus muscle. Two types of anconeus nerve in relation to branches innervating triceps were found: nine nerves also innervated the lateral triceps head, while the other six only contributed two branches to its innervation. The course of the anconeus nerve is important for harvesting as a donor nerve and to protect the nerve in surgical elbow approaches.

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).

Bicortical versus unicortical fixation of plated clavicular fractures: A biomechanical study.

PURPOSE: To compare the biomechanical properties of three plate stabilization techniques for midshaft clavicle fractures: anatomical bicortical locking construct, anatomical unicortical locking construct, and reconstruction bicortical locking construct. METHODS: We analyzed superior plating of the clavicle using an anatomical clavicle plate (Acumed) with both bicortical or unicortical screw fixation and a locking reconstruction plate (DePuy-Synthes). Twenty-one fourth generation composite clavicles were used for non-destructive stiffness testing in axial loading, bending, and torsion. Fifteen composite clavicles and 17 foam clavicles were used for cyclic failure testing using a combined loading method that included all three loading modes. RESULTS: No significant differences were found between the three constructs in torsional stiffness nor in vertical bending loading. In axial loading, the anatomical bicortical locking construct was significantly stiffer than either anatomical unicortical locking construct or the reconstruction bicortical locking construct. The unicortical fixation was also significantly stiffer than the reconstruction bicortical locking construct. Regarding failure testing, there was not a significant difference between the bicortical and unicortical anatomical locking constructs; however, both were significantly stronger than bicortical screw fixation in the reconstruction plate. CONCLUSION: Based on the biomechanical performance of these constructs, unicortical locked plate fixation may be a reasonable option in the treatment of displaced midshaft clavicle fracture fixation.

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.

Trapeziometacarpal osteoarthritis: Arthroscopic hemitrapeziectomy using the Thenar Portal.

BACKGROUND: Although the standard 1Radial and 1Ulnar portals allow for visualisation of most of the trapezium articular surface, the proximity of these two portals can often make arthroscopic triangulation and visualisation of the most lateral capsule and joint surface challenging. Despite its already reported advantages in improving visualisation, there is little literature reporting the clinical experience with the Thenar Portal. The purpose of this study is to describe potential complications and the short-term clinical-radiographic outcomes of arthroscopic hemitrapeziectomy using the Thenar Portal in order to determine its safety and efficacy as a standard working portal. PATIENTS AND METHODS: A retrospective chart review was conducted for all patients diagnosed with first carpometacarpal (CMC) osteoarthritis who were treated surgically with an arthroscopic hemitrapeziectomy. Only patients with stage II or III osteoarthritis and a minimum of 1-year follow-up were included. Twenty-two patients (24 thumbs) with an average age of 62 years met the inclusion criteria. The average follow-up was 52 months. Intra-operative and post-surgical complications were recorded. Objective evaluation consisted of an assessment of range of motion (ROM), grip and pinch strength. Subjective evaluation consisted of a DASH questionnaire and the visual analog scale to score pain at rest, during activities, and function. RESULTS: There were no intra- or post-surgical complications. In one case, pain persisted with a poor functional result, requiring a revision surgery. Average range of motion (compared with the contralateral) showed a statistically significant improvement in palmar abduction and radial abduction of the CMC joint: 50° vs. 55° (p=0.01235), and 50° vs. 55° (p=0.06009), respectively. There was no statistically significant improvement in thumb adduction, grip strength, or lateral and tip-pinch. All patients achieved retropulsion with their affected thumb. According to the VAS, average rest pain improved from 7.5 to 0 (p<0.001) and from 9 to 0 (p<0.001) during activity. The average final function and QuickDASH were 9 (VAS) and 8, respectively (p<0.001). The average radiographic proximal migration of the first metacarpal was 2.9mm (range: 0.7-5.8mm). DISCUSSION: Arthroscopic hemitrapeziectomy using the Thenar portal: 1) improved visualisation of the trapeziometacarpal joint, 2) facilitated arthroscopic triangulation, and 3) represents a safe and effective alternative for the treatment of thumb osteoarthritis, with pain relief and function improvement in most patients without a higher risk of complications. LEVEL OF EVIDENCE: IV.

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.
