RESUMEN

PURPOSE: Recent biomechanical studies have highlighted the importance of foveal reinsertion when repairing triangular fibrocartilage complex (TFCC) injury with foveal tears. However, clinical studies comparing different repair techniques are scarce. We compared the clinical outcomes of suture anchor repair and rein-type capsular suture in patients with TFCC palmer 1B foveal tears with a minimum of 2-year follow-up. METHODS: This was a single-surgeon, single-center, retrospective, comparative study. We included patients who underwent TFCC repair surgery due to a foveal tear from December 2013 to October 2018 with a minimum follow-up of 24 months. Postoperative Quick Disabilities of Arm, Shoulder, and Hand (QuickDASH) score, Modified Mayo Wrist Score, visual analogue scale for pain, wrist range of motion, and grip strength were compared. We also measured the maximal ulnar head displacement with dynamic ultrasound to quantify distal radioulnar joint stability. RESULTS: In total, 103 patients were in the suture anchor group (group A) and 84 patients in the rein-type capsular suture group (group B). The mean follow-up time exceeded three years for both groups. There was a minimal difference regarding QuickDASH score, visual analogue scale for pain, and grip strength ratio between the two groups. The rein-type group had significantly better Modified Mayo Wrist Score. The suture anchor group showed better distal radioulnar joint stability with dynamic ultrasound, but was more limited in ulnar deviation. However, these differences are most likely clinically insignificant. CONCLUSIONS: Both suture anchor repair and rein-type capsular suture yielded satisfactory results for TFCC 1B foveal tear in a minimum of 2-year follow-up. The functional scores were similar, and no major complications or recurrent instability were noted in either group. TYPE OF STUDY/LEVEL OF EVIDENCE: Retrospective Therapeutic Comparative Investigation IV.

RESUMEN

BACKGROUND: The surgical technique of radius distraction for stabilization of distal radioulnar joint (DRUJ) if intraoperative DRUJ instability was found after the fixation of distal radius fracture has been previously described, but this surgical technique lacks clinical and radiographic effect in minimal 3 years follow-up. We therefore evaluated the clinical outcome and radiographic results of radius distraction in minimal 3 years follow-up as long-term evaluation. METHODS: We reviewed the case series of distal radius fracture with concomitant DRUJ instability receiving radius distraction from the senior author over a 5-year period (January 1st, 2013, to June 30th, 2017) retrospectively. Radius distraction during volar plating was performed by moving the volar plate distally via compression screw loosening/fastening to achieve firm endpoint on the dorsopalmar stress test. The evaluations of radiographic, including bone union time and ulnar variance, and clinical outcomes, including grading of DRUJ instability, NRS of wrist pain, DASH score, MMWS score, and range of motion of operated wrist at final follow-up, were performed at clinic as minimum 3-year follow-up; a total 34 patients had been evaluated. RESULTS: At minimal post-operative 36 months follow-up, all cases demonstrated acceptable wrist range of motion with stable DRUJs, low NRS of wrist pain (0.6, SD 0.7), and satisfactory DASH score (mean 9.1, SD 6.2) and MMWS score (mean 87, SD 10). There were no cases suffering from nonunion of distal radius. The mean ulnar variance of injured wrist and uninjured wrist were -1.2 mm and 0.2 mm, respectively (SD 1.0 and 0.6) with significant statistical difference. CONCLUSIONS: Radius distraction during volar fixation of distal radius fracture should be considered if DRUJ instability was found by the dorsopalmar stress test intraoperatively, and the long-term DRUJ stability could be achieved by maintenance of normal-to-negative ulnar variance, with decreased wrist pain and satisfactory function outcome. LEVEL OF EVIDENCE: Therapeutic Level IV.

RESUMEN

INTRODUCTION: Fixed-angle plate fixation can be an effective treatment for distal radius fractures (DRFs). However, patients with existing ulnar positive variance might be at risk of developing symptoms of ulnar-sided wrist pain (USWP). Ulnar shortening osteotomy (USO) is one of the main treatment options for USWP. We hypothesized that a limited radial distraction at the fracture site at the time of surgery for DRF would be functionally equivalent to an indirect USO and that if this were done in a patient with an ulnar plus morphology it could potentially decrease the risk of USWP. METHODS: This retrospective study was conducted at a single institution and all the surgeries were performed by single surgeon. A total of 136 patients (92 women and 44 men) with a mean age of 55 years were enrolled with 57 patients in the distraction group (from 2014 to 2017) and 79 patients (from 2011 to 2013) in the non-distraction group. Patients were assessed USWP. Functional outcomes were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Visual Analogue Scale (VAS) for pain, grip strength, and range of motion for the wrist. RESULTS: The mean follow-up was 37.9 months (range, 28-61 months). The radiographs at postoperative 2-year follow-ups showed the mean ulnar positive variance was 1.3 mm (range, 1-2 mm) in the distraction group and 3.5 mm (range, 2-5 mm) in the non-distraction group. The average of the distraction length was 2.32 mm (range, 2-3 mm). At the 2-year follow-ups, USWP presented in 7% (four patients) in the distraction group, which was significantly less than the incidence of 28% (22 patients) in the non-distraction group. The distraction group exhibited significantly better DASH scores and grip strength and less subsequent ulnar-shortening osteotomy for ulnar-sided wrist pain. CONCLUSIONS: The radial distraction procedure performed during DRFs fixation could possibly reduce the occurrence of postoperative USWP and improve the functional outcomes. LEVEL OF EVIDENCE: Level III, Therapeutic.

RESUMEN

BACKGROUND: Dynamic radiocarpal instability is one of the causes of post-trauma radial-sided wrist pain. It is not easy to diagnose and may possibly be overlooked. The key ligaments responsible for dynamic radiocarpal instability are the radioscaphocapitate (RSC) and long radiolunate (LRL) ligaments. Tensioning of these 2 ligaments could be a method of treatment for dynamic carpal instability. We proposed a method for arthroscopic thermal shrinkage of these 2 ligaments, and for setting a landmark arthroscopically to facilitate identification of these 2 ligaments during the combined open suture tensioning procedure. METHODS: Between January 2016 and May 2020, 12 patients treated with this method were enrolled. The mean age was 33.3 years (range, 18-57 years), and the mean duration from injury to operation was 7.8 months (range, 3-25 months). The diagnosis was mainly depended on the physical examinations and confirmed under arthroscopy. The mean follow-up was 17.7 months (range, 12-26 months). RESULTS: All the patients had marked improvement of pain, grip strength, the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), and the radiocarpal stability. The wrist range of motion showed significant decrease around 5o in both flexion and extension and around 4o in the ulnar deviation at the final follow-ups. All patients were able to return to their previous full level of work and activities. CONCLUSIONS: We conclude that arthroscopic thermal shrinkage combined with open suture tensioning can be effective in treating dynamic carpal instability, while the arthroscopic-assisted landmark setting can help identify the accurate location of the RSC and LRL ligaments without dissecting too much soft tissue.

RESUMEN

INTRODUCTION: Distal radius mal-unions often cause radius shortening and ulnar impaction syndrome. The modern treatments of ulnar impaction syndrome following distal radius mal-union are ulnar shortening osteotomy (USO) and distal radius lengthening osteotomy (DRLO). However, there are few studies to compare long-term outcomes of these two treatments. This study compares isolated USO to DRLO for the treatment of ulnar impaction syndrome following distal radius mal-union. MATERIALS AND METHODS: We retrospectively reviewed 68 patients with extra-articular distal radius mal-unions treated by isolated USO in 36 patients and DRLO in 32 patients. Pain visual analog scale (VAS), wrist motion, grip strength, radiographic parameters including sigmoid inclination, DASH score, and perioperative complications were analyzed. Mean follow-up was 62.6 months. RESULTS: The postoperative VAS scores for pain on exertion were less in the DRLO group than the USO group (1.2 vs. 2.8, p = 0.02). The DASH scores were 16.7 and 29.8 in the DRLO and USO groups, respectively (p = 0.02). The reduction of pain and improvement of function showed significantly better in the DRLO group. The mean operative time was shorter in the USO group. Most of the sigmoid inclinations were changed in DRLO. There were two re-operations following USO for painful nonunion and two patients had subsequent DRUJ osteoarthritis at the last follow-up. CONCLUSION: Although both treatments improved range of motion, grip strength, and VAS for pain, DRLO was found in better reduction of pain and improvement of function. USO is a simpler procedure with a shorter operative time but it has an increased potential to cause subsequent osteoarthritis of the DRUJ as its incongruity of DRUJ after USO especially in reverted inclination. DRLO can be a preferred method for treating USWP in relevant distal radial mal-union.

RESUMEN

BACKGROUND: Ulnar shortening osteotomy (USO) is an effective treatment for ulnar impaction syndrome. However, there have been reports of osteoarthritis (OA) at the distal radioulnar joint (DRUJ) when USO was performed on patients with a reverse oblique sigmoid notch. This study aimed to evaluate the radiographic and functional outcomes following USO in patients with a reverse oblique sigmoid notch. METHODS: We retrospectively reviewed patients having a reverse oblique sigmoid notch who underwent USO for ulnar impaction syndrome between 2002 and 2013. We evaluated radiographic changes of the DRUJ and functional outcomes of patients. RESULTS: We enrolled 22 patients (22 wrists) with an average age of 49.6 years and a mean follow-up of 93.2 (range, 36-179; standard deviation [SD], 38.2) months. We found that there were changes in the inclination angle of the sigmoid notch, from an average reverse oblique of 14.9o (range, 11o-23o; SD, 3.4o) preoperatively to a more parallel 5.1o (range, 0o-11o; SD, 3.2o) at the final follow-up. The functional results at the final follow-up were good, with a mean visual analogue scale for pain of 0.2 (range, 0-1; SD, 0.4) at rest and 1.3 (range, 0-3; SD, 0.9) during activity, QuickDASH of 15.1 (range, 2.3-34.1; SD, 8.8), and modified Mayo Wrist Score of 91.6 (range, 70-100; SD, 6.4). Seven wrists (31.8%) had changes compatible with OA, but the wrists did not exhibit a significantly worse function when compared to wrists without OA changes, except for supination motion and grip strength. CONCLUSIONS: For patients with a reverse oblique sigmoid inclination following USO, we observed that the inclination angle had a tendency to become parallel and some patients developed OA at the DRUJ. However, long-term functional outcomes could still be good. The reverse oblique sigmoid inclination does not seem to be an absolute contraindication for USO.

RESUMEN

PURPOSE: The treatment of delayed union and established nonunion of the scaphoid using a volar approach with impaction of bone graft, either a cancellous or cortico-cancellous wedge graft, for osteosynthesis and maintenance of reduction. With the advancement of instruments and techniques of wrist arthroscopy, wider indications for wrist problems can be solved by this minimally invasive technique. We report our results of arthroscopic reduction, cancellous bone grafting to the regional distal radius, and headless screw fixation for the treatment of scaphoid nonunion, even with humpback deformity. METHODS: Between August 2014 and February 2018, 41 patients (42 wrists) with unstable scaphoid nonunion received arthroscopic surgery. The mean follow-up was 38.1 months (range 24-70 months). We evaluated the results with a function questionnaire and clinical outcomes based on the visual analog scale (VAS) pain score, range of motion and grip strength, and radiologic measurements. RESULTS: The union rate was 92.6% (38/41 patients) and union time was 4.6 months. Patients regained almost a full range of motion compared with the contralateral wrist. The post-op Quick DASH, Mayo wrist score, and VAS pain score all had significant improvement, with p < 0.05. The scapholunate angle showed significant correction from pre-op 68.0° to post-op 58.3°. The average VAS satisfaction score at final follow-up was 8.7. CONCLUSION: Arthroscopic realignment and osteosynthesis for the treatment of unstable scaphoid nonunion with ipsilateral radius bone graft, even with humpback deformity, can achieve a high union rate, good radiological correction, and good functional recovery.

RESUMEN

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To compare the surgical results between targeted therapy and post-operative chemotherapy for patients with spinal metastasis of inoperable non-small-cell lung cancer (NSCLC). SETTING: Single-center study at an academic orthopedic department in Taiwan. METHODS: Sixty-five patients were treated surgically for spinal metastasis of inoperable NSCLC with long posterior instrumentation with or without posterior decompression according to the patient's neurologic status. Post-operative radiotherapy of the spinal lesion and targeted therapy or chemotherapy were done following surgery after the surgical wound healed. Post-operative clinical outcomes and survival were evaluated and compared between these two groups. The overall survival represented survival from the date of diagnosis to death. RESULTS: Thirty-five patients were grouped as the targeted therapy group and 30 patients as the chemotherapy group. The overall median survival times were 12.0 and 10.0 months in the targeted therapy and chemotherapy groups, respectively. Sixty-two patients were able to walk with or without an aid postoperatively. There was no significant difference observed between these two groups in terms of pain relief, neurologic improvement, ambulatory improvement, and survival. CONCLUSIONS: Surgical stabilization with or without laminectomy improved functional outcomes in patients with inoperable non-small-cell lung cancer, and post-operative functional outcomes were similar between chemotherapy and targeted therapy groups. A longer survival was observed with targeted therapy for the patients whose NSCLC was diagnosed before spinal metastasis, however, the longer survival was not statistically significant.

RESUMEN

BACKGROUND: There are some difficulties in treating proximal scaphoid nonunion, mainly including poor vascularity of the proximal scaphoid fragment and limited space for a stable fixation in the proximal scaphoid fragment. This study reports the outcomes of treating proximal scaphoid nonunion with arthroscopic assist for reduction, bone grafting and screw fixation across the scapholunate (SL) joint. METHODS: Between 2008 and 2017, 21 patients were enrolled. Fracture healing and change in the lateral SL angle and SL gap were evaluated. Functional outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand (DASH) score, wrist range of motion, grip strength, and the Visual Analog Scale (VAS) for pain. RESULTS: Nineteen patients achieved fracture healing and their mean follow-up duration was 31.3 months (24-120 months). The average fracture healing time was 16.3 weeks (10 to 28 weeks). From the preoperative to the postoperative final evaluation, there was some significant improvement in wrist function, including wrist flexion from 54.5o to 67.4o, wrist extension from 62.3o to 71.7o, DASH scores from 52.4 to 21.4, VAS during activity from 4.6 to 2.1, and grip strength from 9.6 kg to 24.7 kg. The lateral SL angle also improved significantly, from 82o to 66o. Seventeen patients requested screw removal after fracture healing because of their cultural belief in not leaving hardware in the body. No significant SL gap widening was noted after screw removal in the sequential follow-ups. CONCLUSIONS: Using arthroscopic-assisted reduction, bone grafting and screw fixation across the SL joint in proximal scaphoid nonunion treatment, satisfactory functional and radiographic outcomes can be achieved.

RESUMEN

BACKGROUND: Safe placement of pedicle screws without jeopardizing neurovascular structures medially and anteriorly is important during spine surgery. Inferior breach of pedicle is also dangerous due to low margin of error. Lumbar morphology and identical pedicle orientation at L1 to L5 shown on CT scan of young Taiwanese patients (90 patients) were analyzed and compared with findings reported for Caucasian subjects. METHODS: Previously reported techniques were employed to quantitatively elucidate the parameters regarding lumbar morphology and identical pedicle orientation at each vertebra. The parameters for pedicle angle (PA), pedicle diameter (PD), pedicle axis distance (PAD), midline axis distance (MAD), transverse pedicle axis distance (TPAD) and transverse intertangential angle (TITA) were measured. RESULTS: Taiwanese subjects had different PA, PD, PAD, MAD at L1 to L5 and TITA at L3 to L5 compared with Caucasian subjects. L5 had the most convergent pedicle axis, the widest PD and the shortest antero-posterior axis morphology. CONCLUSIONS: This study provides detailed information for identifying pedicle orientation during pedicle screw placement and elucidate racial differences in lumbar morphology and pedicle orientation between Taiwanese and Caucasian populations.

RESUMEN

PURPOSE: To investigate the clinical features in carriers of X-linked retinitis pigmentosa, X-linked ocular albinism, and choroideremia (CHM) using multimodal imaging and to assess their diagnostic value in these three mosaic retinopathies. METHODS: We prospectively examined 14 carriers of 3 X-linked recessive disorders (X-linked retinitis pigmentosa, X-linked ocular albinism, and CHM). Details of abnormalities of retinal morphology were evaluated using fundus photography, fundus autofluorescence (FAF) imaging, and spectral domain optical coherence tomography. RESULTS: In six X-linked retinitis pigmentosa carriers, fundus appearance varied from unremarkable to the presence of tapetal-like reflex and pigmentary changes. On FAF imaging, all carriers exhibited a bright radial reflex against a dark background. By spectral domain optical coherence tomography, loss of the ellipsoid zone in the macula was observed in 3 carriers (50%). Regarding the retinal laminar architecture, 4 carriers (66.7%) showed thinning of the outer nuclear layer and a dentate appearance of the outer plexiform layer. All five X-linked ocular albinism carriers showed a characteristic mud-splatter patterned fundus, dark radial streaks against a bright background on FAF imaging, and a normal-appearing retinal structure by spectral domain optical coherence tomography imaging. Two of the 3 CHM carriers (66.7%) showed a diffuse moth-eaten appearance of the fundus, and all 3 showed irregular hyper-FAF and hypo-FAF spots throughout the affected area. In the CHM carriers, the structural changes observed by spectral domain optical coherence tomography imaging were variable. CONCLUSION: Our findings in an Asian cohort suggest that FAF imaging is a practical diagnostic test for differentiating X-linked retinitis pigmentosa, X-linked ocular albinism, and CHM carriers. Wide-field FAF is an easy and helpful adjunct to testing for the correct diagnosis and identification of lyonization in carriers of these three mosaic retinopathies.

RESUMEN

Persistent distal radioulnar joint (DRUJ) instability after internal fixation of distal radius fractures can be managed with soft tissue or bony stabilization and prolonged immobilization. However, these strategies limit postoperative motion. To address this limitation, we report our technique of indirect ulna shortening by radial distraction followed by early mobilization and provide a case example. We use this technique in cases of persistent DRUJ instability during standard volar plating of distal radius fractures. Radial lengthening is achieved by distraction through the fracture site using the oblong hole of the plate until DRUJ stability is obtained. No immobilization of forearm rotation and a standard, early mobilization rehabilitation program are used. Indirect ulnar shortening by distraction through the distal radius fracture site provides a simple and novel strategy for the management of persistent DRUJ instability during volar plating, obviating the need for prolonged immobilization or to alter standard postoperative protocols.

RESUMEN

Flexor tendon injury is a rare, but serious, complication after volar plate fixation for distal radius fractures. The plate position and prominence at the watershed line are contributing factors that cause flexor tendon injury. With the standard volar approach, the pronator quadratus (PQ) is typically elevated off the radial attachment. The distal part of the plate is often visible after repair of the PQ. We describe a "PQ-splitting" technique for covering the distal edge of the plate if primary PQ repair cannot completely cover the distal part of the plate. We also report the outcome of our series. This method can potentially prevent direct gliding of flexor tendons on the distal part of the plate and prevent flexor tendon attrition on the plate prominence.

RESUMEN

BACKGROUND: The aim of this study was to examine risk factors associated with the development of diabetic retinopathy (DR) 10 yr after the diagnosis of juvenile-onset type 1 diabetes in Taiwan. METHODS: This retrospective cohort study of 153 individuals with type 1 diabetes for >10 yr duration (mean duration: 13.1 yr) included participants in the Chang Gung Juvenile Diabetes Eye Study. Risk factors assessed for association with DR included age, gender, age at onset and duration of diabetes, self-reported smoking, blood pressure, lipid profile, urinalysis, glycated hemoglobin (HbA1c), body mass index, spherical equivalent, and axial length of the eyeball. RESULTS: There were 128 patients without DR and 25 patients with DR. The mean age at onset was 7.0 ± 4.0 yr (mean ± standard deviation). Cox proportional-hazards analysis showed that older-onset age (p = 0.001), higher HbA1c (p = 0.013), and higher triglyceride concentration (p = 0.015) were the strongest correlates of DR after adjustment for diabetes duration. CONCLUSIONS: Development of retinopathy 10 yr after diagnosis in people with juvenile-onset type 1 diabetes was associated with older onset age, higher HbA1c, and higher triglyceride concentration.

RESUMEN

PURPOSE: To report short-term and long-term outcomes on a single patient cohort observed longitudinally after nerve reconstruction for adult brachial plexus injury. METHODS: Eleven male patients who underwent plexus reconstruction by the same surgeon at 2 institutions presented for clinical examination 7.5 or more years after surgery (average, 11.4 years; range, 7.5-22 years). Average age at the time of operation was 35 years (range, 17-73 years). Mean delay until surgery was 5 months (range, 2-11 months). Two patients had C5 paralysis, 2 had C5-C6 paralysis, 2 had C5-C7 paralysis, and 5 had complete 5-level injuries. Outcome parameters included active range of motion (ROM) in degrees, a modified British Medical Research Council (mBMRC) scale for muscle strength, and electromyographic motor unit configuration and recruitment pattern. Differences in ROM and mBMRC between 2-year and long-term follow-up were assessed with paired-sample t tests using an alpha value of .05. RESULTS: Average shoulder abduction and mBMRC at final follow-up were both significantly improved compared with the 2-year follow-up results (P < .05). Average elbow flexion and mBMRC increased significantly between 2 years and final follow-up (P < .05). Electromyographic results for 6 patients at final follow-up showed improved motor unit configuration in 10 of 15 muscles and improved recruitment in 3 of 15 muscles compared with 2-year electromyographic results. CONCLUSIONS: Patients continued to gain ROM and strength in the shoulder and elbow well after 2 to 3 years after surgery, contrary to previous reports. Although the precise mechanism is unknown, we speculate that a number of factors may be involved, including terminal collateral sprouting, maturation of motor units, improvements in motor unit recruitment, additional muscle fiber hypertrophy, or an as-yet undescribed mechanism. We recommend that patients be encouraged to continue strengthening exercises well after the initial recovery period and that more comparative long-term data be collected to expand on these observations.

RESUMEN

Intra- and extra-articular giant cell tumor of tendon sheath (GCTTS) and pigmented villonodular synovitis (PVNS) are histologically similar, usually benign tumors that can be characterized by synovial involvement (GCTTS) or overgrowth (PVNS). These tumors are most often found in the knee and digits of the hand. Although recurrence is a common feature of both conditions, multifocal lesions are rare. We present an unusual case of multifocal, recurrent, bilateral GCTTS/PVNS involving both upper and lower extremities. Recurrent right ankle and right index finger masses, in addition to masses on the right small finger and left thumb, were excised over a 14-year period.

RESUMEN

Wrist arthroscopy could be a treatment option for dorsal ganglion cysts. To achieve a thorough dorsal capsulectomy for the removal of midcarpal ganglion cysts, it is commonly necessary to combine both the radiocarpal and midcarpal portals. We present a modified method using radiocarpal portals only for arthroscopically excising dorsal midcarpal ganglion cysts. No extra midcarpal portals are necessary, and the method potentially generates satisfactory results.
