RESUMEN
STUDY DESIGN: This was a systematic review with a meta-analysis. INTRODUCTION: Despite rising trends toward surgical treatment of distal radius fractures (DRF) with volar locking plate (VLP) fixation, there is a lack of consensus on when to start vigorous wrist range of motion (ROM) exercises after surgery. PURPOSE: We performed a meta-analysis to compare early and late mobilization after VLP fixation in patients with DRF. METHODS: Four prospective randomized controlled trials with a minimum of 6 months of follow-up were retrieved through MEDLINE (PubMed), EMBASE, Web of Science, the Cochrane Library, and the KoreaMed databases in March 2021. We divided patients into an early group (patients who started ROM exercises of the wrist within 2 weeks after surgery), and a late group (patients who started ROM exercises 5 or 6 weeks after surgery). The primary outcome was treatment efficacy which was measured through improvement in pain score, function score, ROM, and grip power. The secondary outcome was the incidence of postoperative complications. RESULTS: This meta-analysis included 127 patients in the early group and 131 patients in the late group. The outcomes were compared at 6 weeks, 3 months, and 6 months postoperatively. There was no significant difference in pain score, though the early group had a lower average visual analog scale score. The early group had a lower arm, shoulder, and hand disability score than the late group (95 % CI, -16.25 to -8.35 points; P < .001) at 6 weeks postoperatively, suggesting significantly superior outcomes. A similar trend persisted at 3 (n = 74 in the early group and n = 77 in the late group; 95% CI, -5.45 to -0.30; P = .029) and 6 months (n = 102 in the early group and n = 100 in the late group; 95% CI, -4.81 to 0.21; P = .073), but the differences were smaller. The early group had a higher grip power at all follow-up periods, but the difference was only significant at 6 months postoperatively (n = 88 in the early group and n = 83 in the late group; 95% CI, 0.50 to 6.99; P = 0.024). The early group also had more favorable ROM in all directions at 6 weeks, but only in supination at 6 months. The complication rate was not significantly different between the 2 groups. There were no differences in the rates of secondary operation and reduction loss. CONCLUSION: Early ROM exercise after VLP in DRF resulted in superior functional scores and grip power until 6 months postoperatively. The dominance of the joint ROM, which was seen at 6 weeks after surgery in the early exercise group, decreased with time and ultimately showed little difference at 6 months. Early exercise is safe and did not increase complication rates.

PURPOSE: We aimed to compare trigger finger (TF) development between patients with carpal tunnel syndrome (CTS) treated with carpal tunnel release (CTR) and those treated conservatively, using the National Health Insurance Services data of Korea. We also aimed to investigate risk factors for post-CTR TF development. METHODS: We selected CTS patients with or without CTR (3543 patients in each group) between 2002 and 2015. Sex, age, follow-up duration after CTS diagnosis, and comorbidities associated with TF-development were matched using propensity score. We compared the rates of TF diagnosis and subsequent TF operations between groups. Thereafter, we selected patients with CTS undergoing CTR, for whom minimum follow-up exceeded five years. We compared sex, age, height, weight, and comorbidities associated with TF risk factors between the TF-occurrence and non-TF-occurrence groups. RESULTS: On comparing CTR-treated patients with those treated conservatively for CTS, CTR-treated patients presented with significantly higher rates of TF diagnosis (12.2%) and TF operations (4.7%) than patients without CTR (6.2% and 1.2%, respectively). Among 433 TF-diagnosed patients and 166 TF-operated patients after CTR, most were identified < 5 years after CTR, with 379 diagnosed (87.5%) and 147 operated (88.5%) patients. A total of 240 patients presented with newly developed TF over a five year period. Patients with subsequent TF exhibited a higher female sex rate and shorter height. None of the variables was significant risk factors for TF development in logistic regression analysis. CONCLUSION: We confirmed high incidences of post-CTR TF diagnosis and operations. TF develops most frequently in the first postoperative year.

INTRODUCTION: The fifth metacarpal neck fracture is the most common metacarpal fracture. The palmar angulation from the fracture displacement is critical for determining treatment, yet there is no consensus regarding the angulation measurement method or the surgical cut-off value. This study aimed to identify a reliable measurement method for assessing palmar angulation. We evaluated inter-observer and intra-observer validation of measuring palmar angulation in oblique plain X-ray and computed tomography (CT) sagittal cuts. MATERIALS AND METHODS: We identified surgically treated patients for acute isolated fifth metacarpal neck fracture between January 1, 2008, and December 31, 2020, and obtained preoperative, opposite hand, and final follow-up oblique X-rays and sagittal computed tomography (CT) radiograms. The oblique radiograph was taken with a 45° posteroanterior pronation. The metacarpal neck palmar angulation was measured in the radiograms using the metacarpal neck-shaft center (MNSC) angle and the shaft articular surface (SAS) angle methods by three orthopedic surgeons in two sessions. For the CT radiograms, each measurer selected the sagittal slot at their discretion to measure the angle. The final palmar angulation was the average of six measurements (two sessions, three measurers per session). RESULTS: The study included 51 patients; the average age was 32.5 (range 18-73) years, with 46 men and 5 women. The MNSC angle inter-observer reliability was better than the SAS angle. The MNSC angle inter-observer reliability was better than that of SAS angle. Intraclass coefficients (ICCs) for the MNSC angle demonstrated an excellent inter-observer agreement among the three measurers in the first (0.93) and second (0.88) session compared to ICCs for the SAS angle in the first (0.81) and second (0.87) session. The MNSC angle intra-observer reliability was also better than the SAS angle, with higher ICCs. Preoperative CT radiograms were available for 42 patients. Using CT scans for measurements, in the two sessions, the MNSC angle inter-observer reliability was higher than that of the SAS angle [MNSC: 0.83; SAS: 0.35], second [MSNC: 0.85; SAS: 0.81]. The intra-observer reliability was also better in the MNSC angle. When comparing average value among obtained radiograms, the physiologic angulation of the opposite hand oblique X-ray had the smallest average value, followed by preoperative CT and preoperative oblique radiography. Overall, the SAS angle measurement had a slightly larger angle than the MNSC method in the fractured and non-fractured hand measurements. Finally, a serial comparison of the oblique X-rays (pre-and postoperative, final follow-up, and the opposite hand with closed reduction and internal fixation) indicated that the angulation significantly decreased, and the post-operative values did not differ from the final follow-up X-ray for either method. CONCLUSIONS: The palmar angulation measurement in 45° pronated oblique X-ray using the MNSC angle method had good-to-excellent reliability, with superior results to sagittal CT radiograms. Although the angle is likely overestimated, the MNSC method is reliable for judging the fracture degree and reduction adequacy after surgery compared to the non-fractured hand physiologic angulation.

PURPOSE: Carpal tunnel syndrome (CTS) is a common entrapment neuropathy, often requiring carpal tunnel release (CTR) surgery. Often, a nerve conduction study (NCS) is performed before CTR; however, there are various reports questioning the sensitivity of NCS, and some patients do undergo CTR despite normal NCS results. We had the following purposes: (1) to report clinical outcome of CTS patients who undergo CTR despite normal NCS, (2) to identify the characteristics and compare those with abnormal NCS patients in terms of basic features and risk factors, and (3) to analyze and compare normal and abnormal NCS results. MATERIALS AND METHODS: Medical records of 546 CTS (30 normal NCS and 516 abnormal NCS) patients were retrospectively reviewed. Of 30 normal NCS patients, 7 were excluded, leaving 23 patients in the experimental group. We investigated the influence of age, sex, operative arm, and body mass index, as well as medical conditions known to be risk factors for CTS. In normal NCS patients, as a functional score, we investigated Boston carpal tunnel scores before and after CTR. The NCS results were compared in terms of median motor and median sensory testing. In normal NCS patients, NCS data were compared with that of the contralateral nonoperated wrists. RESULTS: There were 18 women and 5 men in the normal NCS group (mean age 43.7 years). On physical examination, 22 (94.7%) patients showed a positive Tinel test, 19 (82.6%) showed a positive Phalen test, 8 (34.8%) complained of nocturnal paresthesia, and only 1 (4.3%) presented with thenar atrophy. In 19 of 23 patients, the Boston CTS scores showed significant improvement after CTR. Normal NCS patients were significantly younger and significantly heavier and more likely to be a current smoker. In NCS analysis of normal NCS patients, the operated wrists were closer to the reference values than nonoperated wrists. CONCLUSIONS: Surgeons should evaluate the possibility of other combined lesions before CTR in normal NCS patients. Normal NCS can be present with a CTS diagnosis, especially in younger patients. Nevertheless, CTR after failed conservative management, despite normal NCS, could relieve subjective symptoms and function.

INTRODUCTION: Distal radius fracture (DRF) is the most common upper extremity fracture. After the introduction of volar locking plate (VLP) fixation, treatment has shifted from conservative management to more operative management. The implant removal rate after VLP fixation in patients with DRF varies and the reasons for removal and associated patient characteristics have not been clearly defined. This study aimed to compare the characteristics of patients who underwent VLP with and without subsequent implant removal. Second, the rate of implant removal according to the implant position and type was investigated. Finally, we summarized clinical outcome with implant removal, the reasons for, and complications associated with implant removal. METHODS: In this retrospective study, patient data were collected between January 1, 2008, and December 31, 2017. The study population was divided into two groups based on subsequent implant removal. Data on patient characteristics, such as age, sex, comorbidities, side of the fractured arm, the AO Foundation and Orthopaedic Trauma Association classification of the DRF, plate position grade based on the Soong classification type, type of inserted plate, insurance coverage, and treatment costs were collected. Furthermore, we investigated the reason for implant removal, clinical outcomes, and post-removal complications. RESULTS: After applying the exclusion criteria, 806 patients with a total of 814 DRFs were included in the study. Among the 806 patients who underwent VLP fixation for DRF, 252 (31.3%) patients underwent implant removal. Among the patients undergoing implant removal, the mean age was 50.8 ± 14.0 years, 94 (37.3%) were male. The average time to implant removal from the fracture fixation was 12.1 ± 9.2 months (range 1-170 months). When comparing groups, patients who underwent implant removal were significantly younger and had fewer cases of diabetes, hypertension, and cancer history. According to the Soong plate position grade, the most common position was G1 in both groups. Although there was no significant difference (p = 0.075), more G2 cases were found in the removal group (15.0%) than in the retention group (10.2%). About 66.5% of the patients with implant removal had other health insurance as well as the national service, compared with 47% of the patients with implant retention. In total, 186 patients (73.8%) underwent implant removal despite being asymptomatic after the bony union. The patient satisfaction scores improved from 4.1 to 4.4 after implant removal, and 93% of the patients answered that they would choose implant removal again. Only 10% of the patients who underwent removal reported minor complications. No major complications were reported. CONCLUSION: Although the implant removal was conducted without clinical symptoms in the majority of patients, overall patients presented improved functional outcomes with implant removal. The evidence is inconclusive regarding its necessity, however, implant removal after VLP fixation for DRF is not a challenging procedure and is not associated with major complications. LEVEL OF EVIDENCE: Level IV.

PURPOSE: Since volar locking plates (VLPs) have the benefits of more stable fixation and fewer complications, VLP osteosynthesis is now the preferred osteosynthesis method in the operative management of distal radius fractures (DRF). Along with the increases in operative management of VLP, the character and frequency of complications have changed. Thus, this multicentre study aimed to identify the characteristics of patients with DRFs who were treated with VLP fixation, describe the complication types and rates related to the procedure, and compare the results with those found in the literature. MATERIAL AND METHODS: This retrospective multicentre study was conducted between January 2008 and December 2017. In total, data from 2225 patients over 17 years old who underwent VLP fixation for DRF were screened. Patients with closed reduction and pinning, external fixation, dorsal plate fixation, and screw-only fixation were excluded. Finally, 1955 wrists from 1921 patients (86.3%) were included. The following types of complications were investigated: (1) tendon injury, (2) nerve-related, (3) fixation- and instrument-related, (4) osteosynthesis-related, (5) infection, and (6) others. RESULTS: The mean age of the patients was 60.3 ± 14.6 years with 587 males (30.6%). Distal ulnar fractures were found in 940 wrists (48.1%). The mean interval between fracture and surgery was 6.2 days, while the mean operative time was 68.3 ± 30.3 minutes. The following complications were found: (1) nine (0.46%) and 12 (0.61%) cases of flexor pollicis longus and complete extensor pollicis longus tears, respectively; (2) nine cases (0.46%) of palmar sensory median nerve branch damage, 15 cases (0.77%) of complex regional pain syndrome, and 36 cases (1.84%) of carpal tunnel syndrome; (3) five cases (0.26%) of fracture displacement even after plate fixation, six cases (0.31%) of screw breakage, 26 cases (1.33%) of radiocarpal joint screw penetration, and 511 cases (26.14%) of implant removal; (4) five cases (0.26%) of delayed union and three cases (0.15%) of non-union; (5) 83 (4.25%) and two (0.1%) cases of superficial and deep infection, respectively; and (6) two cases (0.1%) of compartment syndrome and three cases (0.15%) of radial artery damage. CONCLUSIONS: After 10 years of experience performing VLP fixation for DRFs in a multicentre setting, the results regarding complication types and rates support its use as a reasonable treatment option with low rates of complication.

INTRODUCTION: Displaced unstable distal third fractures of the humeral diaphysis are treated surgically through open reduction and internal fixation. Conventionally, surgeons prefer using long plates for secure fixation; however, we performed short plate dual plating for robust fixation that required a smaller incision and less dissection through an anterior approach. In this study, we report the results of dual plating of fractures of the humeral shaft, with radiographic evidence and clinical analysis. METHODS: This retrospective study included 29 patients with distal third diaphyseal fractures of the humerus. There were 18 men and 11 women, with an average age of 43 years, and a mean follow-up period of 21.2 months. We investigated the type of fracture, plate length, number of fixed screws, and fracture union. Range of motion, Disabilities of Arm, Shoulder, and Hand (DASH) score, and complications during follow-up were analyzed for clinical results. RESULTS: All fractures were classified according to AO classification. We used 4.5-mm narrow locking compression plates (LCP) and 3.5-mm LCP reconstruction plates. Fracture union was achieved in all cases during the follow-up. All patients recovered favourable elbow range of motion at final follow-up. At the final follow-up, average DASH score was 10.0, and no patient showed postoperative complications. CONCLUSIONS: Satisfactory radiographic evidence and clinical results suggest that dual plating for distal diaphyseal humeral fractures may be considered a surgical option, with the advantages of strong fixation, less invasion of soft tissue, and early rehabilitation.

Intraarticular fracture of the metacarpophalangeal (MP) joint presents complex problems related to the sophisticated functional aspects of the hand. Injury to the metacarpal head may have a severe effect on hand function but few studies have investigated the management of this condition. In this study, we applied open reduction and internal fixation for the displaced fracture of the metacarpal head and report the clinical and radiographic outcomes of our experience. Thirteen patients (12 men, 1 woman; mean age 21 years) were included in this study, and medical records and radiographs were reviewed retrospectively. The average follow-up period was 12.5 months. Range of motion (ROM) and Disabilities of the Arm, Shoulder, and Hand (DASH) scores were analyzed, and functional results and serial radiographs were investigated for the maintenance of articular congruity and fracture union. The injured fingers were 5 long, 4 small, 2 ring, and 2 index. Five cases were fixed with Kwires, 5 cases with headless screws, and 3 cases with screw and Kwire. The average range of injured MP joint motion was 89°, total active range of motion (TAM) was 265°, and the average DASH score was 3.8 at the last follow-up. All patients showed fracture union on the radiographs and no patient showed significant articular surface incongruence or degenerative change. Open reduction and internal fixation of the metacarpal head fracture had favorable outcomes in our study. The authors suggest accurate reduction and stable fixation for better functional results in metacarpal head fractures.

BACKGROUND: Angiofibroblastic changes of a musculotendinous origin at the medial epicondyle characterize medial epicondylitis of the elbow. Although nonsurgical treatment is the primary approach for medial epicondylitis, surgical treatment should be considered when conservative therapy fails. This study reports the results of surgical treatment of medial epicondylitis monitored for more than 5 years. METHODS: This study included 55 patients with 63 cases of medial epicondylitis between 2000 and 2010. The conservative treatment periods lasted for a minimum of 1 year, and steroid injections were administered more than twice before surgery. One surgeon conducted the surgical procedures. The Nirschl and Pettrone grades, visual analog scale (VAS) scores, Disabilities of the Arm, Shoulder and Hand (DASH) scores, Mayo Elbow Performance scores, and grip strengths were analyzed. Statistical analyses were performed using paired t tests. RESULTS: The mean VAS score improved from 8.5 to 2.4 (P <.001). Nirschl and Pettrone grades rated 43% (27 elbows) as excellent and 51% (32 elbows) as good. The Mayo Elbow Performance scores improved from 72 to 88 (P <.001) and DASH scores from 57 to 23 (P <.001). The mean grip strength of the affected side improved from 30 to 43 lb (P <.001). The mean time required to return to work and exercise was 2.8 months and 4.8 months, respectively. One case of heterotrophic ossification, which had no functional instability afterward, was seen. CONCLUSION: The results indicate that surgical treatment of medial epicondylitis could be an effective and safe treatment when conservative treatment fails.

BACKGROUND: A contralateral normal hip joint has been often used as a reference standard in preoperative planning and intraoperative assessment of hip arthroplasty, with the assumption that bilateral hip joint geometries have no significant differences. However, one previous study using analog measurements on hardcopy films reported significant bilateral variation in hip joint geometry. We therefore investigated the level of agreement between the right and left hips for each measurement and determined index values and the range of normal bilateral variations. METHODS: We assessed 100 standard anteroposterior radiographs of the pelvis in this study. Two independent observers measured the actual value of femoral head diameter, location of the femoral head center, acetabular offset, femoral offset, hip offset, greater trochanteric height, neck-shaft angle, medullary canal diameter, and proximal femoral diameter. Intraclass correlation coefficients (ICCs) and values of mean difference were calculated for each measurement. RESULTS: The results demonstrated perfect agreement (ICC >0.8) between the right and left hips for most parameters and substantial agreement for greater trochanteric height (ICC = 0.735) and femoral offset (ICC = 0.773). The mean difference and standard deviation in the measurement between the right and left hips for the location of the femoral head center and the acetabular offset were 0.60 ± 0.48 mm and 0.42 ± 0.30 mm, respectively. CONCLUSION: Hip joint geometry is not influenced by side. In hip arthroplasty, a contralateral normal hip can be reliably used as a guide for preoperative planning using measurement tools on a picture archiving and communication system.

PURPOSE: To analyze the clinical and radiologic outcomes of arthroscopic cyst decompression and labral repair in patients with inferior paralabral cysts with chronic shoulder pain. METHODS: Between March 2006 and September 2012, 16 patients who were identified as having inferior paralabral cysts presented with chronic shoulder pain. All patients underwent a thorough physical examination and preoperative magnetic resonance arthrographic evaluation. The mean age was 30 years (range, 17 to 50 years). The mean follow-up period was 38 months (range, 16 to 60 months). Clinical outcome scores (American Shoulder and Elbow Surgeons; University of California, Los Angeles; and Simple Shoulder Test) and passive shoulder range of motion were evaluated at last follow-up. Follow-up magnetic resonance imaging was performed at a mean of 8 months to determine the labral healing status and assess for cyst recurrence. RESULTS: The incidence of isolated inferior paralabral cysts was 0.6% (16 of 2,656 cases). Of the patients, 8 had multiple cysts and 8 had a single cyst. The mean length and width of the cysts were 1.0 cm and 0.4 cm, respectively. Eight cases had a history of trauma, and 13 patients were involved in sports activities. Seventy-five percent of cases showed a positive relocation test. The mean American Shoulder and Elbow Surgeons; University of California, Los Angeles; and Simple Shoulder Test scores improved from 64, 22, and 8.7, respectively, preoperatively to 83, 31, and 10, respectively (P < .001), at final follow-up. Shoulder range of motion did not show any significant improvement. The location of the labral tear was as follows: anteroinferior tear in 5 cases, posteroinferior tear in 8 cases, and combined anteroinferior and posteroinferior tear in 3 cases. All cysts were found to be in association with a labral tear. A mean of 2.7 anchors were used for inferior labral repair. These cysts were found only in male patients. None of the patients showed any evidence of cyst recurrence on follow-up magnetic resonance imaging. CONCLUSIONS: Inferior labral tears treated with cyst decompression and labral repair showed satisfactory clinical results without any recurrence. Inferior paralabral cysts should be considered in the differential diagnosis in patients presenting with chronic shoulder pain, particularly active male patients. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Tumoral calcinosis is an uncommon disorder and characterized by development of calcified masses within the soft tissues near the large joints such as the hip, elbow, and shoulder and rarely occurs in the foot. We report a case of tumoral calcinosis at the first meta-tarso-phalangeal (MTP) joint of foot with hallux valgus deformity associated with bunion which required resection. Surgical excision of the calcific mass alone, without surgery to the minimal hallux valgus, resulted in resolution of symptoms, without recurrence of the lesion. Subsequently, speculative etiology, differential diagnostic considerations as well as the therapeutic interventions for tumoral calcinosis are discussed taking into consideration the current literature. We conclude that tumoral calcinosis should be considered in the differential diagnosis of a painful mass that develops in the small joints of the foot.

Background: Pediatric trigger digit (TD) does not appear at birth but is diagnosed after birth by finding a flexion contracture of the thumb or other fingers. The reported incidence of pediatric TDs varies from 0.5 to 5 cases per 1,000 live births without sex-specific predominance. We performed a nationwide large-scale study to determine the prevalence and incidence of pediatric TDs and analyzed operative treatment for pediatric TDs using the National Health Insurance data of South Korea. Methods: Patients with pediatric TDs, aged 0-10 years between 2011 and 2020, were included in this study. Children born between 2011 and 2015 were set as the reference population and followed up until 2020. We calculated the prevalence and incidence rates of pediatric TDs according to age and sex and analyzed the operation rate, age at surgery, time interval from initial diagnosis to surgery, and follow-up period. Patient selection and treatment were based on International Classification of Diseases, 10th Revision (ICD-10). Results: The prevalence rates of pediatric TDs ranged from 0.063% to 0.084%. Girls had a higher prevalence rate (0.066%-0.094%) than boys (0.060%-0.075%). The total incidence rate was 77.6/100,000 person-years, and the incidence rate was higher in girls (84.8) than in boys (70.7). Among 2,181,814 children born between 2011 and 2015, 12,729 were diagnosed with pediatric TDs, of which 1,128 (8.9%) underwent operative management. The means of age at initial diagnosis, age at surgery, and the time interval between diagnosis and operation were 2.76 ± 1.91 years, 3.79 ± 2.19 years, and 1.15 ± 1.71 years, respectively. Conclusions: High prevalence and incidence rates of pediatric TDs were found in 2- to 3-year-old patients. Among pediatric patients, 8.9% underwent operative management that was most frequently conducted between 2 and 3 years of age (within 1 year of initial diagnosis).

Background: Distal metaphyseal-diaphyseal junction fractures of the humerus are a subset of injuries between humeral shaft fractures and distal intra-articular humerus fractures. A lack of space for distal fixation and the unique anatomy of concave curvature create difficulties during operative treatment. The closely lying radial nerve is another major concern. The aim of this study was to determine whether anterolateral dual plate fixation could be effective for a distal junctional fracture of the humerus both biomechanically and clinically. Methods: A right humerus 3-dimensional (3D) model was obtained based on plain radiographs and computed tomography data of patients. Two fractures, a spiral type and a spiral wedge type, were constructed. Three-dimensional models of locking compression plates and screws were constructed using materials provided by the manufacturer. The experiment was conducted by using COMSOL Multiphysics, a finite element analysis, solver, and simulation software package. For the clinical study, from July 2008 to March 2021, a total of 72 patients were included. Their medical records were retrospectively reviewed to obtain patient demographics, elbow range of motion, Disabilities of the Arm, Shoulder and Hand (DASH) scores, Mayo Elbow Performance Scores (MEPS), and hand grip strength. Results: No fracture fixation construct completely restored stiffness comparable to the intact model in torsion or compression. Combinations of the 7-hole and 5-hole plates and the 8-hole and 6-hole plates showed superior structural stiffness and stress than those with single lateral plates. At least 3 screws (6 cortices) should be inserted into the lateral plate to reduce the load effectively. For the anterior plate, it was sufficient to purchase only the near cortex. Regarding clinical results of the surgery, the range of motion showed satisfactory results in elbow flexion, elbow extension, and forearm rotation. The average DASH score was 4.3 and the average MEPS was 88.2. Conclusions: Anterolateral dual plate fixation was biomechanically superior to the single-plate method in the finite element analysis of a distal junctional fracture of the humerus model. Anterolateral dual plate fixation was also clinically effective in a large cohort of patients with distal junctional fractures of the humerus.

Authors chose anterior approach through the antecubital fossa for better exposure in that case of isolated coronoid process fracture. The objective of the study was to report validity of anterior approach for the Regan and Morrey type III, isolated fracture of the coronoid process of the ulna without residual valgus or varus instability. From January 2007 and January 2010, we evaluated eleven consecutive patients (7 men, 4 women; mean age 44 years; range 25-67 years) who underwent surgical fixation through the anterior approach. The mean follow-up period was 21 months (range 15-34 months). Preoperative and follow-up roentgenograms were evaluated for assessment of the fracture configuration and confirmation of fracture union. Clinical evaluation included an analysis of surgical complication, range of motion, Mayo elbow performance score, and DASH (disability of the arm, shoulder, and hand) score. Fractures were mainly fixed with plate and screws in 8 cases, cannulated screws in 3 cases. There was no residual joint instability after fracture fragment fixation. All fractures were united, and the average union time was 15.2 weeks with a range of 11-20 weeks. Mean flexion contracture of the elbow was 3.6° (range 0°-10°), and further flexion was 130.9° (range 125°-140°) at the last follow-up. Mean Mayo elbow performance score was 92.3 (range 80-100 points), and mean DASH score was 5.9 (range 1.6-8.3 points). In conclusion, Primary fixation of the coronoid process fractures through the anterior approach could be particularly useful in the Regan and Morrey type III isolated coronoid process fractures.

A 60-year-old woman presented functional deficit of the index finger flexor digitorum profundus (FDP) tendon after shoulder arthroscopic rotator cuff repair. As no recovery was observed for 10 months, we conducted an operative exploration of the median nerve and the anterior interosseous nerve, followed by an external neurolysis. The patient recovered FDP function 4.5 months after the second operation. In a patient with persistent isolated FDP dysfunction after shoulder arthroscopy, operative exploration and external neurolysis could facilitate functional recovery. Level of Evidence: Level V (Therapeutic).

BACKGROUND: Radial head and neck fracture is a common fracture around the elbow. It is mostly caused by axial or valgus loading after a fall in elbow extension and forearm pronation. When a radial head and neck fracture occurs, the capitellum collides with the radial head and experiences a shear force, leading to capitellum fracture. The primary aim of this study was to evaluate the incidence of concurrent capitellum fracture and analyze its patterns among patients treated for radial head and neck fractures based on computed tomography. Secondary aim is to determine factors associated with concurrent capitellum fractures. HYPOTHESIS: Capitellum fractures are more common than expected in radial head and neck fractures and show a consistent pattern. With the higher the Mason type fracture, the higher the incidence of concurrent capitellum fracture will be shown. METHODS: A total of 101 patients treated surgically (27 patients) or non-surgically (74 patients) for radial head and neck fractures from January 2017 to December 2020 were retrospectively analyzed. Initial computed tomography was reviewed to identify concurrent capitellum fractures. A fracture was diagnosed when the bone continuity was lost in two consecutive images in any one of the three directions of computed tomography scan images. Seventeen patients with capitellum fractures were classified as group 1 and 84 patients without capitellum fractures as group 2. Each group of patients was assessed using Mason classification, whether fracture extended to the radial neck or not, fracture location, and treatment method. To determine the fracture location, radial head was trisected using three anatomical landmarks: safe zone, posteromedial zone, and anteromedial zone. And it was determined as the location where the fracture was most comminuted. RESULTS: The average age of the 101 patients was 44.6 years old. There were 54 (53.5%) males and 47 (46.5%) females. Capitellum fracture was accompanied in 17 cases. Its incidence was 16.8%. The rate of accompanying capitellum fracture was 9.5% (6/63) for Mason type 1, 25.0% (6/24) for Mason type 2, and 41.7% (5/12) for Mason type 3. The ratio of radial neck extension of fracture was significantly higher in group 2. There was no isolated radial neck fracture in group 1. However, there were 33 in group 2. After eliminating isolated radial neck fracture patients, significantly more fractures were located in the safety zone in group 1. Group 1 had a significantly higher rate of surgical treatment than group 2 (52.9% (9/17) vs. 21.4% (18/84) p=0.007). CONCLUSION: For radial head and neck fractures, the higher the Mason type fracture, the higher the incidence of concurrent capitellum fracture. When the fracture extended to the radial neck, the comorbidity of the capitellum fracture was decreased. Among radial head fractures, when the fracture was located in the safe zone, the comorbidity of capitellum fracture was increased. The rate of surgical treatment was higher in radial head and neck fracture patients with concurrent capitellum fractures. LEVEL OF EVIDENCE: IV; diagnostic study.

Background: A flexion contracture (FC) of the proximal interphalangeal (PIP) joint can have a profound negative influence on daily activity. The outcomes of surgical release of the PIP joint in literature are based on small sample size studies done several decades ago. The aim of this study is to report the outcomes of surgical treatment for post-traumatic FC of the PIP joint and to identify factors that affect these outcomes. Methods: This single institute retrospective study included patients from 2000 to 2020. We only included patients with post-traumatic FC of the PIP joint. We evaluated the demographic characteristics, cause of FC, surgical approaches and the various procedures conducted. We surveyed postoperative complications. During the study period, we asked about their current symptoms and evaluated their operative outcomes as excellent, good, fair or poor through the phone. Results: The average FC recovery angle was 37.3°. The small finger was the most affected, and the most common cause of FC was a tendon laceration. The volar plate complex release was the most frequently conducted procedure. The FC improvement was positively correlated to the degree of preoperative FC. The more severe preoperative flexion-extension arc was presented, the more FC recovery was achieved after operation. Patients who underwent multiple procedures had a higher degree of preoperative FC, and better correction was achieved with multiple procedures than with a single procedure. The most critical complication was recurrence. Conclusions: We were able to obtain average 37.3° of extension by surgical treatment. The more severe the FC presented before surgery, the greater the need for multiple procedures, however, this resulted in a significant increase in joint extension. Nevertheless, caution should be exercised regarding recurrence and could occur even with an experienced surgeon. Level of Evidence: Level IV (Therapeutic).

BACKGROUND: Wrist pain on the ulnar side is often caused by ulnar impaction syndrome (UIS). Idiopathic UIS requires surgical treatment when conservative treatment fails. The 2 main surgical procedures used are the wafer procedure and ulnar shortening osteotomy (USO) of the metaphysis or diaphysis. This review aimed to analyze comparative studies of the 2 procedures in UIS to determine clinical outcomes and complications. METHODS: One prospective and 5 retrospective comparison trials were retrieved from the PubMed, Embase, and Cochrane Library databases. The primary outcomes were treatment effectiveness; pain visual analog scale (VAS), disabilities of the arm, shoulder, and hand (DASH) score, Mayo wrist, and Darrow scores. The incidence of postoperative complications formed the secondary outcome. RESULTS: The selected studies included 107 patients who underwent the wafer procedure (G1) and 117 patients who underwent USO (G2). The wafer procedure had the benefits of less postoperative immobilization and an early return to work. However, there were no significant differences in the postoperative pain improvement and functional scores. All 6 studies reported high total complication rates and reoperation with USO. The most frequent complication was implant-related discomfort or irritation; subsequent plate removal was the most common reason for a secondary operation. CONCLUSIONS: There was no difference in pain improvement or the postoperative functional score between the groups. Nevertheless, postoperative complications were the major pitfalls of USO. As the specialized shortening system advances further, a high-level study will be necessary to determine the surgical option in UIS.

Multiple dorsal fracture-dislocations of the carpometacarpal joints (CMCJ) occur from very high-energy trauma and are often associated with soft tissue injury or ischaemia. We report a 54-year-old male manual worker and a smoker who presented to the emergency room with history of compression of his right hand in a press machine. Radiographs showed dorsal fracture-dislocations of the scapho-trapezio-trapezoidal and third to fifth CMCJ's. Despite emergent Guyon canal and carpal tunnel release and closed reduction and pinning, skin pallor persisted in all digits. Brachial angiography revealed total occlusion of the radial and ulnar arteries and loss of the palmar arch at the level of the fracture. Heparin and Alprostadil were injected directly. On follow-up angiography three weeks later, the vessels were still occluded and collaterals provided digital circulation. Although digital sensations recovered, cold intolerance and stiffness resulted in a poor functional outcome. Level of Evidence: Level V (Therapeutic).
