RESUMEN
Background@#Although several techniques for the treatment of ulnar impaction syndrome (UIS) have been introduced, there have still been reports on various complications such as delayed union, nonunion, refracture, wrist pain, plate irritation, and chronic regional pain syndrome. This study aimed to compare the differences in radiological and clinical outcomes of patients in which intramedullary bone grafting was performed in addition to plate stabilization with those without additional bone grafting during ulnar shortening osteotomies (USOs). @*Methods@#Between November 2014 and June 2021, 53 wrists of 50 patients with idiopathic UIS were retrospectively reviewed. Patients were divided into 2 groups according to whether intramedullary bone grafting was performed. Among the 53 wrists, USO with an intramedullary bone graft was performed in 21 wrists and USO without an intramedullary bone graft was performed in 32 wrists. Demographic data and factors potentially associated with bone union time were analyzed. @*Results@#There was no significant difference between the 2 groups when comparing postoperative radioulnar distance, postoperative ulnar variance, amount of ulnar shortening, and postoperative Disabilities of the Arm, Shoulder and Hand score. Compared to the without-intramedullary bone graft group, bone union time of the osteotomy site was significantly shortened, from 8.8 ± 3.0 weeks to 6.7 ± 1.3 weeks in the with-intramedullary bone graft group. Moreover, there were no cases of nonunion or plate-induced symptoms. Both in univariable and multivariable analyses, intramedullary bone grafting was associated with shorter bone union time. @*Conclusions@#USO with an intramedullary bone graft for idiopathic UIS has favorable radiological and clinical outcomes. The advantage of this technique is the significant shortening of bone union time.
RESUMEN
Background@#Although pregnant or lactating women have been recognized to be predisposed to de Quervain’s tenosynovitis (DQT), there is a lack of epidemiologic evidence. The purpose of this study was to estimate the nationwide incidence of pregnancy-related DQT (PRDQT) and to analyze risk factors using the Korean National Health Insurance (NHI) database. @*Methods@#A retrospective epidemiologic study of pregnant women in South Korea from 2013 to 2017 was conducted using the NHI claims database. Using corresponding diagnostic codes, we identified women diagnosed with DQT during pregnancy or the postpartum period. We calculated the cumulative incidence and analyzed risk factors such as demographics, pregnancy type, delivery method, gestational complications, and comorbidities using multivariate logistic regression analysis. @*Results@#Between 2013 and 2017, 34,342 patients with PRDQT were identified among 1,601,501 pregnant women, representing a cumulative incidence of approximately 2.1%. Age ≥ 30 years, multiple gestation, cesarean delivery, hypertensive disorders in pregnancy, and underlying rheumatoid arthritis were all identified as significant risk factors for the occurrence of PRDQT, whereas diabetic disorders in pregnancy and underlying diabetes mellitus were not. @*Conclusions@#In South Korea, PRDQT was found to affect approximately 2.1 out of 100 pregnant women between 2013 and 2017. The incidence and risk factors identified in this study can be used for clinical consultations and prediction, as well as for development of national health policies.
RESUMEN
Background@#Previous literatures suggest that the prognosis of Kienböck’s disease might be favorable despite no surgery if it is diagnosed in late age, but the evidence is not clear. The aim of this study was to determine the radiographic and clinical progression of Kienböck’s disease diagnosed at more than 50 years of age. @*Methods@#Data of 27 patients diagnosed with Kienböck’s disease at more than 50 years of age between 2000 and 2016 were investigated. During the study period, no treatment, either surgical or nonsurgical, was applied. We explained to the patients that the affected lunate was not expected to collapse further if found late in age. Annual visits were recommended, through which radiographic and clinical observation was made. We assessed changes in Stahl index and radioscaphoid angle between the initial assessment and the final follow-up, and clinical assessment was made using pain in visual analog scale (VAS) and Dornan’s criteria. @*Results@#Initially, 2 patients were in Lichtman stage 1, 6 in stage 2, 5 in stage 3A, 11 in stage 3B, and 3 in stage 4. Radiographic follow-up of at least 5 years (mean, 7.8 years) was made in 14 patients, whose Stahl index and radioscaphoid angle did not differ significantly from their initial measurements. Arthritic appearance was not found, and progression in the Lichtman stage was detected in 1 lunate, from 3A to 3B. Despite no surgical treatment for an average of 7.5 years (range, 5.0–15.7 years) of observation period in the 27 patients, average pain in VAS improved from 3.5 (range, 1–7) to 0.8 (range, 0–2), with excellent or good clinical status by Dornan’s criteria. @*Conclusions@#Our study suggests that Kienböck’s disease diagnosed at more than 50 years of age can follow a benign natural course in radiographic and clinical aspects. Therefore, surgical interventions should be considered carefully in this age group.
RESUMEN
Distal radius fractures (DRFs) are one of the most common fractures seen in elderly people. Patients with DRFs have a high incidence of osteoporosis and an increased risk of subsequent fractures, subtle early physical performance changes, and a high prevalence of sarcopenia. Since DRFs typically occur earlier than vertebral or hip fractures, they reflect early changes of the bone and muscle frailty and provide physicians with an opportunity to prevent progression of frailty and secondary fractures. In this review, we will discuss the concept of DRFs as a medical condition that is at the start of the fragility fracture cascade, recent advances in the diagnosis of bone fragility including emerging importance of cortical porosity, fracture healing with osteoporosis medications, and recent progress in research on sarcopenia in patients with DRFs.
RESUMEN
PURPOSE: Pediatric intra-articularproximal phalangeal head fractures of the big toe are very rare and few studies on this have been published. The purpose of this study is to present the diagnostic approach and surgical management of these extremely rare fractures, which might be easily underestimated or misdiagnosed.MATERIALS AND METHODS: The study retrospectively reviewed all the patients who were diagnosed as intra-articular proximal phalangeal head fracture of the big toe and who underwent surgical intervention in our institution. The size of the bony fragment and hallux valgus interphalangeus angle were measured on the preoperative X-rays. The size and rotation of the osteochondral fragment, the presence of avascular necrosis, ligamentous injury and soft tissue entrapment were assessed on the preoperative magnetic resonance images (MRIs). The radiologic and functional evaluation were performed at 1 year postoperatively.RESULTS: The average size of the bony fragments measured on the X-rays was 4.1 mm in width and 2.3 mm in length. Two cases showed hallux valgus interphalangeus. Preoperative MRI was performed in four cases and the average size of any osteochondral lesion was 5.3 mm in width, 3.9 mm in length, and 4.7 mm in height. Rotation of the osteochondral fragment was observed in one patient, and soft tissue entrapment was noted in two patients. Postoperatively, successful bony union was achieved in all the patients and the average time to union was 74.4 days.CONCLUSION: Intra-articular proximal phalangeal head fractures of the big toe are very rare and often neglected due to incomplete ossification in the pediatric population. It is important to suspect the presence of this intra-articular fracture and to appropriately implement further evaluation. Nonunion of chronic cases as well as acute fractures can be successfully treated through open reduction and internal fixation using multiple K-wires.

BACKGROUND: It is difficult for surgeons to reconstruct soft tissue defects of the great toe. This report aims to evaluate the utility and efficacy of innervated distally based first dorsal metatarsal artery (FDMA) flap with a wide pedicle for reconstruction of soft tissue defects of the great toe. METHODS: This is a retrospective report. Between January 2015 and December 2017, six cases of skin defect of the great toe were reconstructed with an innervated distally based FDMA flap with a wide pedicle. One case was excluded in this report because of chronic pain on the metatarsophalangeal joint due to osteoarthritis before the injury. A total of five cases were evaluated for flap survival and sensory recovery. The sensory recovery was investigated by two-point discrimination and Semmes-Weinstein monofilament tests. The average age of the selected patients was 40 years (range, 36 to 56 years), and the average size of the defect in the toe was 8.3 cm2 (range, 4 to 13.8 cm2). The average follow-up period was 29.4 months (range, 18 to 38 months). RESULTS: All patients survived without any complications. The average two-point discrimination test value was 8.0 ± 0.89 mm (range, 7 to 9 mm), and the average value obtained from the Semmes-Weinstein monofilament test was 4.53 ± 0.33 (range, 4.17 to 4.93). The average residual pain score evaluated with a visual analog scale was 1 (range, 0 to 2). Two patients complained of stiffness in the great toe below 30° of total range of motion during the early stages after surgery, but this stiffness gradually improved after rehabilitation. The average range of motion of three patients with a remaining metatarsophalangeal joint after surgery was 80° (range, 70° to 90°). All five cases could walk regularly without any unique footwear at the final follow-up. CONCLUSIONS: The innervated distally based FDMA flap with a wide pedicle could be a good alternative method for repair of soft tissue defects of the great toe.

BACKGROUND: The Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH) is one of the most widely used questionnaires for assessing functional ability of the patients with upper extremity diseases. Carpal tunnel syndrome (CTS) is the most common neuropathic disease in the upper extremities. The aim of this study was to verify the validity, reliability, and responsiveness of Korean version of QuickDASH questionnaire (K-QuickDASH) in the patients with CTS. METHODS: In total, 83 subjects who underwent open carpal tunnel release (CTR) operation were selected. They fulfilled Korean version of Disabilities of the Arm, Shoulder and Hand questionnaire (K-DASH) and K-QuickDASH at two different time points: before and six months after the surgery. Both criterion-related and construct validities were evaluated using Pearson's correlation coefficient and factor analysis. Internal consistency was estimated using Cronbach's alpha, and test-retest reliability was assessed to verify the reliability of K-QuickDASH using intraclass correlation coefficient (ICC). The standardized response mean and the effect size were analyzed to confirm the responsiveness of the K-QuickDASH in CTS patients. RESULTS: Significant positive correlation was found between K-QuickDASH and K-DASH. All the questionnaire items were categorized into three factors. Acceptable internal consistency was confirmed in three categories of K-QuickDASH. A high test-retest reliability and responsiveness of K-QuickDASH were detected. CONCLUSION: K-QuickDASH in Korean patients with CTS was confirmed to have high degree of validity and reliability, and responsiveness after CTR. Therefore, the K-QuickDASH would be a good evaluation tool for evaluating clinical symptoms and determination of treatment outcomes in the patients with CTS.

BACKGROUND: A skin defect of the hand and wrist is a common manifestation in industrial crushing injuries, traffic accidents or after excision of tumors. We reconstructed a skin defect in the ulnar aspect of the hand and wrist with a perforator-based propeller flap from the ulnar artery. The aims of our study are to evaluate the utility and effectiveness of this flap and to discuss the advantages and disadvantages of the flap in hand and wrist reconstruction with a review of the literature. METHODS: Between April 2011 and November 2016, five cases of skin defect were reconstructed with a perforator-based propeller flap from the ulnar artery. There were four males and one female. The age of patients ranged from 36 to 73 years. Skin defect sites were on the dorso-ulnar side of the hand in three cases and palmar-ulnar side of the wrist in two cases. The size of the skin defect ranged from 4 × 3 cm to 8 × 5 cm. We evaluated the viability of the flap, postoperative complication and patient's satisfaction. RESULTS: There was no failure of flap in all cases. The size of the flap ranged from 4 × 4 cm to 12 × 4 cm. One patient, who had a burn scar contracture, presented with limited active and passive motion of the wrist after the operation. The other patients had no complications postoperatively. Cosmetic results of the surgery were excellent in one patient, good in three patients, and fair in one patient. CONCLUSIONS: The fasciocutaneous propeller flap based on a perforating branch of the ulnar artery is a reliable treatment option for the ulnar side skin defect of the hand and wrist.

PURPOSE: The purpose of this study was to suggest a multimodal diagnostic approach to determine the cause of the disease in patients diagnosed with synovitis of the wrist and who underwent synovectomy. MATERIALS AND METHODS: Twenty-nine patients, who underwent contrast magnetic resonance imaging (MRI) preoperatively and synovectomy from January 2000 to December 2013, were reviewed retrospectively. Among them, 17 patients underwent a Tc99m white blood cell (WBC) scan preoperatively. In patients who met the diagnostic criteria of rheumatoid arthritis (RA), the diagnosis was confirmed as RA if the MRI finding or histology was compatible with RA. If the MRI finding and histology were disparate, the final diagnosis was made based on the histologic finding. RESULTS: Of the nine patients who met the diagnostic criteria of RA, seven patients were finally diagnosed as RA and two patients as tuberculous arthritis. Of the 20 patients who did not meet the diagnostic criteria of RA, the MRI findings and histology were consistent with the same disease in 12 patients. In the remaining eight patients, five were diagnosed with nonspecific chronic synovitis, one with RA, and two with tuberculous arthritis based on the clinical findings, MRI, and histology findings. CONCLUSION: MRI and a WBC scan are very useful imaging modalities for diagnosing the causative condition of the wrist synovitis. A histology evaluation after synovectomy can also be useful in cases with a difficult diagnosis or are refractory to medications.

Ulnar impaction syndrome is one of the common causes of ulnar-sided wrist pain. The pain is usually aggravated by ulnar deviation during a power grip, especially when the forearm is in a pronated position. The most common predisposing factor of ulnar impaction syndrome is ulnar positive variance, which is an increased ulnar length relative to the radius of the radiocarpal joint. However, it can also occur in patients with ulnar neutral or negative variance because ulnar variance can increase during functional activities, including pronation and power gripping. In these patients, the triangular fibrocartilage complex (TFCC) may be thickened. If conservative treatments—lifestyle modification, medication, or wrist splinting—are unsuccessful, surgical treatments, such as wafer procedure or ulnar shortening osteotomy can be considered. The wafer procedure is an effective treatment for ulnar impaction syndrome. It removes the distal 2 to 4 mm of the ulnar head, while preserving the ulnar styloid process from fracturing via a limited open or an arthroscopic approach. The advantages of the wafer procedure are that it does not require bone healing or internal fixation and provides direct access to TFCC. However, it is a technically demanding procedure and is contraindicated in patients with distal radio-ulnar joint (DRUJ) instability, lunotriquetral instability, ulnar minus variance, and with an ulnar positive variance of more than 4 mm. Ulnar shortening osteotomy is the most popular method for the treatment of ulnar impaction syndrome. It can effectively relieve ulnar impaction symptoms and stabilize DRUJ. However, an excessive amount of shortening may increase the peak pressure at DRUJ, which results in DRUJ arthritis. There is also a possibility of delayed union or nonunion in the osteotomy site. To prevent delayed union or nonunion, we should make an effort to decrease the gap in the osteotomy site during surgery. A serial follow-up is also recommended to evaluate the occurrence of arthritis in DRUJ after ulnar shortening.

BACKGROUND: Radius osteotomies showed favorable clinical outcome in Kienböck's disease. However, few articles have been published on the long-term outcome of lateral wedge osteotomy of the radius in patients with advanced stage Kienböck's disease. METHODS: Eleven patients with Lichtman stage IIIB/IV Kienböck's disease (group A; mean follow-up period, 86.1 months; range, 48 to 163 months) and 14 patients with Lichtman stage IIIA Kienböck's disease (group B; mean follow-up period, 85.1 months; range, 49 to 144 months) underwent radial wedge osteotomy between August 2004 and August 2012. Radiological changes of the lunate and radiocarpal joint were compared between two groups after osteotomy. The wrist flexion/extension angle, grip strength, and Disabilities of the Arm, Shoulder and Hand (DASH) scores were evaluated preoperatively and at the final follow-up. The Nakamura Scoring System (NSSK) was used for comprehensive understanding of radiological and clinical outcomes. RESULTS: Nine patients of group A and 11 patients of group B showed radiological improvement in the lunate regarding sclerosis, cystic changes, or fragmentation. No patients showed progression of arthritic changes in radiocarpal and midcarpal joints. The wrist flexion/extension angle, grip strength, and DASH score were significantly improved in both groups after operation, but intergroup difference was not statistically significant at the final follow-up (p = 0.149, p = 0.267, and p = 0.536, respectively). The mean NSSK was 21.6 (range, 15 to 27) in group A and 21.8 (range, 15 to 26) in group B. CONCLUSIONS: Radial wedge osteotomy yielded excellent radiological and functional outcomes in advanced stages of Kienböck's disease and these results were comparable to those of Lichtman stage IIIA disease. This technique could be a useful alternative to salvage procedures in the treatment of Lichtman stage IIIB/IV Kienböck's disease without severe radiocarpal arthritis.

BACKGROUND: To determine whether olecranon fractures have osteoporotic features such as age-dependent, low bone attenuation and low-energy trauma as a cause of injury. METHODS: Elbow computed tomography (CT) and medical record review were performed in 114 patients (53 males and 61 females) with acute olecranon fractures. The mean age was 57 years. Bone attenuation was measured on the central part of the olecranon on sagittal CT images avoiding the fracture, and on the distal humerus (distal metaphysis and medial and lateral condyles) on coronal CT images. We compared bone attenuation and causes of injury (high or low energy trauma) between younger (<50 years) and older (≥50 years) patients in each gender. Multiple regression analysis was performed to determine the effect of age and gender on bone attenuation. RESULTS: Mean bone attenuation in older male and female patients was significantly lower than in younger patients, except at the medial condyle in men. The proportion of low-energy trauma in older male patients was significantly higher than in younger male patients. In female patients, low-energy trauma was predominant in both younger and older patients. Age and female gender had significantly negative effects on bone attenuation. CONCLUSIONS: This study demonstrated that olecranon fractures have osteoporotic features, including age-dependent low bone attenuation and low-energy trauma as the predominant cause of injury. Our results suggest that osteoporosis evaluation should be considered for patients aged 50 years or more with olecranon fractures.

PURPOSE: Though clavicle fractures are the second most common fractures to occur in active adults, there have been a few epidemiological studies conducted on the Korean population in recent years. To better understand clavicle fractures, an epidemiological study reflecting the changes in current life style and injury mechanism may be important. Hence, the purpose of this study was to conduct an epidemiological study on the Korean population. MATERIALS AND METHODS: This was a retrospective study of 973 patients (977 cases) who presented with clavicle fractures from January 2000 to August 2015. Radiological results were classified by the Allman system-3 groups and 7 subgroups. The study collected information regarding gender, age at the event of injury, injury mechanism, other associated injuries, occurrence rate of each year, and seasonal variation. RESULTS: The study consisted of 627 male patients (64.4%, 1 bilateral case) and 346 female patients (35.6%, 3 bilateral cases). The mean age at the time of injury was 31.8±24.9 years (male, 31.2±22.6 years; female, 32.7±28.7 years). Midshaft clavicle fractures (Allman group I) were the most common with 758 cases (77.6%). There were 397 cases with displacement (40.6%). The occurrence of clavicle fractures decreased with increasing age in male patients and showed a bimodal distribution in female patients. Injury due to a fall from standing height was the most common mechanism of injury. There were 61 cases (6.2%) who had other associated injuries and the most common associated injury was a rib fracture. The occurrence of clavicle fractures increased with time, and falling was associated with the highest occurrence rate of clavicle fractures. CONCLUSION: The mean age of clavicle fracture was 31.8 years in a recent 15-year period. The occurrence of fracture in male patients was 1.8 times than female patients, primarily occurring as midshaft fractures. There were more cases of displacement than minimally displaced cases. The most common injury mechanism was a fall from standing height, and the occurrence of clavicle fractures has shown an increasing trend recently.

PURPOSE: The purpose was to evaluate fragment reduction feasilibty when applying extension block Kirschner-wire technique for bony mallet finger. METHODS: We treated 48 displaced mallet finger fractures by a two extension block Kirschner-wire technique. Among these operation group, we found dorsal rotation of fragment in 18 cases, making it difficult to get anatomical reduction. The patients were divided into two groups. One group of 30 patients did not show dorsal rotation of fragment and anatomical reduction was achieved easily. Another group of 18 patients showed dorsal rotation of fragment and additional methods was applied to achieve anatomical reduction. RESULTS: Joint surface involvement was significant greater in groups showing dorsal rotation of fragment than group which did not show (57.1% and 49.7%, respectively) (p=0.01). The groups whose joint surface involvement more than 50% had higher risk of dorsal rotation of fragment than the group less than 50%, with the odds ratio of 6.11. CONCLUSION: We could encounter the cases which showed dorsal rotation of the fracture fragment when treating the bony mallet finger with extension block K-wire technique especially the joint surface involvement was more than 50%. So if we can evaluate the extents of joint surface involvement and prepare additional method preoperatively when dorsal rotation of fragment is expected, it is possible to get more favorable results.

PURPOSE: The reconstruction of femur and tibia defects following tumor resection remains a surgical challenge. The clinical outcome of free vascularized fibula graft (VFG) reconstruction with locking plate for massive femur and tibia defects of more than 10 cm that were secondary to skeletal tumor resection is reported. MATERIALS AND METHODS: Thirteen patients with a mean follow-up of 3.3 years were reviewed. Seven patients received vascularized fibula grafts in the femur and six in the tibia. The mean bony defect of the femur and tibia was more than 10 cm and the length of the grafted fibula was more than 15 cm. All defects were stabilized with long locking plates. RESULTS: All patients were free of disease at final follow-up; All VFGs were transferred successfully. All patients had a successful outcome with bony union. Stress fractures of the grafted fibula had occurred but the locking plate stabilized the fracture and healed until the last follow-up. All patients were able to walk without a brace after a mean of 9 months postoperatively. CONCLUSIONS: VFG with locking plate is a reliable reconstructive procedure for massive femur and tibia defects.

PURPOSE: We report on the clinical result after coverage of a soft tissue defect on the medial foot and ankle with an adipofascial flap based on the perforator from the posterior tibia artery. MATERIALS AND METHODS: Nine patients with soft tissue defects on the medial foot and ankle area from March 2009 to May 2014 underwent the procedure. Average age was 54 years old (range, 8~82 years). There were five male patients and four female patients. The causes of the defect were trauma (4), tumor (3), and infection (2). The pivot point of transposition of this flap is the lower perforator originating from the posterior tibia artery. The fatty tissue side of this flap could be used to resurface the defect. The donor site was closed primarily with the preserved skin, and a small caliber drain tube was used. The split-thickness skin graft was grafted to the flap and the wound. If the wound was still infected, this skin graft could be performed at a later date. RESULTS: All flaps survived and normal soft tissue coverage was obtained for the medial foot and ankle of all patients after the skin graft. Normal footwear was possible for all cases because of thin coverage. There was an extension contracture on the medial ray of the foot, which was resolved by contracture release and skin graft. CONCLUSIONS: For the medial foot and ankle soft tissue defect, the medial crural adipofascial flap based on a perforator branch of the posterior tibia artery could be a good option to cover it.

Postoperative heterotopic ossification of the elbow after surgery for treatment of acute trauma such as fractures and ligament/tendon ruptures has been well-documented. However, literature concerning heterotopic ossification after medial epicondylectomy is scarce. We report on two cases of heterotopic ossification that occurred following medial epicondylectomy for medial epicondylitis and for cubital tunnel syndrome. Preoperatively, calcifications around the medial epicondyle were observed in both patients. These cases suggest that medial epicondylectomy, in the presence of pre-existing calcifications, may pose an increased risk of postoperative heterotopic ossification of the elbow.

BACKGROUND: Patients undergoing ambulatory surgery under general anesthesia experience considerable levels of postoperative nausea and vomiting (N/V) after their discharge. However, those complications have not been thoroughly investigated in hand surgery patients yet. We investigated factors associated with postoperative N/V in patients undergoing an ambulatory hand surgery under general anesthesia and determined whether patients' satisfaction with this setting is associated with postoperative N/V levels. METHODS: We prospectively evaluated 200 consecutive patients who underwent ambulatory hand surgeries under general anesthesia to assess their postoperative N/V visual analogue scale (VAS) levels during the first 24 hours after surgery and their satisfaction with an ambulatory surgery setting. Potential predictors of postoperative N/V were; age, sex, body mass index, smoking behavior, a history of postoperative N/V after previous anesthesia or motion sickness, preoperative anxiety level and the duration time of anesthesia. We conducted multivariate analyses to identify factors associated with postoperative N/V levels. We also conducted multivariate logistic regression analyses to determine whether the N/V levels are associated with the patients' satisfaction with this setting. Here, potential predictors for satisfaction were sex, age, postoperative pain and N/V. RESULTS: Postoperative N/V were associated with a non-smoking history, a history of motion sickness and a high level of preoperative anxiety. Twenty-two patients (11%) were dissatisfied with the ambulatory setting and this dissatisfaction was independently associated with moderate (VAS 4-7) and high (VAS 8-10) levels of postoperative N/V and with a high level (VAS 8-10) of postoperative pain. CONCLUSIONS: Although most of the patients were satisfied with the ambulatory surgery setting, moderate to high levels of N/V were associated with dissatisfaction of patients with this setting, suggesting a need for better identifying and managing those patients at risk. The information regarding risk factors for N/V could help in preoperative patient consultation regarding an ambulatory hand surgery under general anesthesia.

BACKGROUND: It is not clear whether the pronator quadratus (PQ) muscle actually heals and provides a meaningful pronation force after volar plating for distal radius fractures (DRFs). We aimed to determine whether the length of the PQ muscle, which is dissected and then repaired during volar plating for a DRF, affects the forearm rotation strength and clinical outcomes. METHODS: We examined 41 patients who requested hardware removal after volar plating. We measured the isokinetic forearm rotation strength and clinical outcomes including grip strength, wrist range of motion, and disabilities of the arm, shoulder and hand (DASH) scores at 6 months after fracture fixation. During the hardware removal surgery, which was performed at an average of 9 months (range, 8.3 to 11.5 months) after fracture fixation, we measured the PQ muscle length. RESULTS: The average PQ muscle length was 68% of the normal muscle length, and no significant relationship was found between the PQ muscle length and the outcomes including isokinetic forearm rotation strength, grip strength, wrist range of motion, and DASH scores. CONCLUSIONS: This study demonstrates that the length of the healed PQ muscle does not affect isokinetic forearm rotation strength and clinical outcomes after volar plating for DRFs. The results of this study support our current practice of loose repair of the PQ that is performed by most of the surgeons to prevent tendon irritation over the plate, and suggest that tight repair of the PQ is not necessary for achieving improved forearm function.
