RESUMO
Atraumatic subcutaneous rupture of the finger flexor tendon of the hand and forearm is rare. Most sites of closed and subcutaneous ruptures of the finger flexor tendon are the tendon-bone insertion and musculotendinous junction, and an intratendinous lesion is unusual. We report the case of a 76-year-old female who presented to our department with a one-month history of a soft tissue mass and limited flexion of the left middle finger without trauma. Preoperative magnetic resonance imaging revealed a soft tissue mass that caused limited finger flexion. Intraoperative findings showed an intratendinous rupture of the flexor digitorum profundus tendon at the middle phalanx; the lesion was resected to obtain smooth grinding of the tendon. One year postoperatively, the soft tissue mass and limited flexion of the finger resolved without recurrence.
RESUMO
Background: The forearm connects the wrist and elbow joints, and its stability depends on the two articulations, the proximal and distal radioulnar joints, and the interosseous membrane complex. The aim of this case report is to present an acute case of longitudinal radioulnar dissociation with humeral capitellum fracture. Case presentation: A 48-year-old man suffered longitudinal radioulnar dissociation with humeral capitellar fracture following a motorcycle accident. Surgical treatment consisted of open reduction with an iliac bone graft using a buttress posterolateral plate for capitellar fracture, repair of the triangular fibrocartilage complex for distal radioulnar joint, and pinning for interosseous membrane complex. At 2 years postoperatively, plain radiographs showed bony union of the capitellum and maintained ulnar variance. Conclusions: The mainstay of treatment was to reduce the proximal migration of the radius. Physicians must pay attention to the forearm instability when see the patient with humeral capitellum fracture.
RESUMO
Juxta-articular myxoma (JAM) is a rare soft tissue tumour predominantly composed of mucinous tissue and usually found around large joints. We report a 73-year-old woman with a 5-year history of a soft tissue mass in the thenar eminence of the right wrist who presented to our department. An initial diagnosis of a ganglion cyst was made using magnetic resonance imaging (MRI) and the jellied content of the mass by aspiration. Two years after presentation, surgical treatment with tumour resection and carpal tunnel release via the radial approach was performed because the symptoms of carpal tunnel syndrome worsened, and the tumour invaded the carpal tunnel. Histopathological examination revealed a JAM. At the 1-year follow-up, the symptoms of carpal tunnel syndrome had resolved, and no recurrence was confirmed by MRI. Level of Evidence: Level V (Therapeutic).

Background The clinical results of replantation for an amputated distal finger are functionally acceptable. However, few reports exist regarding sequential clinical postoperative recovery. The purpose of this study was to examine the clinical recovery at every 3 months up to 1 year postoperatively. Methods Nineteen patients (16 patients were men), representing 19 fingers with complete amputation at Tamai's zone 1 and replanted successfully, were included in this study. Total active motion (TAM), grip strength (GS), Semmes-Weinstein monofilament (SW) test result, static two-point discrimination (s2PD), and Disability of the Arm, Shoulder, and Hand (DASH) score questionnaire results were obtained postoperatively at 3, 6, 9, and 12 months. Pulp atrophy and nail deformity were assessed at 12 months postoperatively. Results The postoperative %TAM (compared to the uninjured side, 81.8 ± 18.1 at 3 months vs. 91.5 ± 11.9 at 6 months, p < 0.01), %GS (compared with the uninjured side, 61.3 ± 25.9 at 3 months vs. 78.3 ± 20.4 at 6 months, p = 0.02), s2PD (excellent and good/poor; 7/12 at 3 months vs. 18/1 at 6 months, p < 0.01), and DASH scores (26.1 ± 23.1 at 3 months vs. 12.0 ± 12.9 at 6 months, p < 0.01) recovered significantly from 3 to 6 months but did not change significantly from 6 months onward. The SW test results showed a significant recovery between 3 and 12 months postoperatively (2.83 and 3.61/4.31, 6.65, and undetectable, 1/18 at 3 months vs. 7/12 at 12 months, p = 0.04). The DASH score at 12 months postoperatively was significantly associated with %TAM ( r = -0.64, p < 0.01) and %GS ( r = -0.58, p < 0.01) at 12 months postoperatively and age ( r = 0.52, p = 0.02). Five fingers had pulp atrophy and four fingers had nail deformity. Conclusion This 1-year follow-up study showed the sequential clinical recovery after replantation for complete amputation in Tamai zone 1. Postoperative %TAM, %GS, and the DASH score recovered significantly between 3 and 6 months but significant recovery up to 1 year was not observed.
RESUMO
The reconstruction for mild tissue loss at the distal part of a finger is challenging. We report about a 29-year-old man presenting with traumatic tissue loss at the distal interphalangeal (DIP) joint of the index finger, including skin, bone, and nerve. Reconstruction using two types of flaps was performed. The dorsal skin flap, nourished by the second dorsal metacarpal artery (SDMA) perforator, was elevated. The vascularized second metacarpal bone, nourished by the SDMA, was also elevated. Using the vascular connection between the DMA and the palmar digital artery (PDA), both flaps were raised to the distal part of the finger, and the pivot point was set at the dorsal proximal phalanx. After arthrodesis of the DIP joint with the vascularized second metacarpal bone, the digital nerve was repaired using the cutaneous nerve in the skin flap, and the skin defect was covered using the perforator flap. The postoperative course, including flap survival and bone union, was uneventful. A good indication for the reconstruction of the distal part of a finger with this technique is when the defect sizes of the skin and bone differ and the vascular connection between the SDMA and dorsal branch of PDA is not injured.
RESUMO
PURPOSE: Volar locking plate fixation for distal radius fractures (DRFs) is a technically demanding procedure with a risk of distal screw penetration through the dorsal cortex or the articular surface. This study aimed to investigate the incidence and details of distal screw penetration after volar locking plate fixation for intra-articular DRFs using a CT scan and to evaluate the relationship between the incidence of screw penetration and fracture comminution severity and the clinical complications of screw penetration. METHODS: This was a retrospective case series of 91 adult patients (mean age, 63 years; 27 men) who underwent volar locking plate fixation for intra-articular DRFs from 2015 to 2018. The positioning of the distal screws was evaluated using a postoperative CT scan, and radiological outcomes were compared between the AO C1 and C3 groups. At the final follow-up, tendon rupture and arthritis severity were assessed as clinical complications of dorsal and intra-articular screw penetration. RESULTS: Distal screw penetration was observed in 44 wrists (48%), dorsal cortex screw penetration in 34, intra-articular screw penetration in 13, and both dorsal cortex and intra-articular screw penetration in three. The incidence of intra-articular screw penetration was significantly higher in the C3 group than in the C1 group. No tendon rupture was observed. Multivariable analysis revealed that intra-articular screw penetration was significantly related to high severity of arthritis. CONCLUSIONS: Approximately half of the study patients with intra-articular DRFs had distal screw penetration. The incidence of intra-articular screw penetration was associated with the severity of fracture comminution, and the intra-articular screw penetration was associated with the incidence of early radiocarpal arthritis. Intra-articularly penetrating screws should be replaced as soon as they are discovered, regardless of the length of penetrated screw or absence of patients' subjective symptoms. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Background: We surgically treated comminuted radial head and neck fractures using headless compression screws, including multiple screws for the radial head and a single oblique screw for the radial neck. This study aimed to compare the clinical and radiological results for comminuted radial head and neck fractures between surgery using headless compression screws with a single oblique screw for the radial neck, our new procedure, and a plate system precontoured to the proximal radius. Methods: This retrospective study included 23 patients (11 and 12 in the screw and plate groups, respectively). The fractures were type 3 according to the Mason-Johnston classification modified by Broberg and Morrey. Clinical outcomes analyzed included the motion range of the elbow and forearm, Mayo Elbow Performance Score, and radiological assessments. In addition, postoperative complications were also investigated. The average follow-up was 18 months. Results: The bone union was achieved in all the patients, and there were no significant differences in clinical outcomes and radiological assessments except forearm supination (p = 0.02). Furthermore, additional surgical procedures were performed in one and five patients in the screw and plate groups, respectively (p = 0.16). Posterior nerve palsy was observed in two patients in the plate group. Complications were observed in one and six patients in the screw and plate groups, respectively (p = 0.07). Conclusion: Both surgical procedures achieved good clinical and radiological outcomes with bone and ligament injury repair. The screw group had a greater range of forearm supination than the plate group.
RESUMO
Axial carpal dislocations and fracture-dislocations are rare injuries involving derangement of the carpal arches. Several surgical approaches have been reported as a means of treatment, including the use of closed or open reduction and internal fixation. However, to our knowledge, surgical treatment using arthroscopy has not been reported so far. Here we present the case of a 54-year-old man who experienced peritrapezium axial carpal dislocation while reversing his car. Minimally invasive surgery using arthroscopy was performed because of severe swelling of the hand. Reduction under arthroscopic assistance using midcarpal portals was performed based on the relationship between the trapezium and trapezoid, and fixed wires were inserted. Wires were removed at six weeks postoperatively, and range-of-motion exercises of the wrist joint were started. At one-year postoperative follow-up, the patient was asymptomatic, with no difficulties while performing daily activities and work. Computer tomography images revealed an anatomical carpal arch without traumatic arthrosis. Arthroscopy-assisted surgery enabled us to anatomically reduce fracture-dislocation of the trapezium and assess the injury path.
RESUMO
Posttraumatic cubitus varus deformity in pediatric patients may cause second fractures of the distal humerus. Corrective osteotomy is used to obtain good alignment and is generally performed for patients with prolonged deformity or bony union after fracture. We report the case of a 10-year-old boy who presented with elbow pain after falling. Plain radiography showed lateral condylar fracture and cubitus varus deformity. This injury was the fourth fracture of the same distal humerus. Open reduction and internal fixation for lateral condylar fracture and lateral closing wedge osteotomy for cubitus varus deformity were performed simultaneously. At the last follow-up, one and a half years after operation, plain radiography showed closure of the physis of the distal humerus, and coronal alignment was maintained. The patient was asymptomatic and satisfied with cosmetic issues. There was no fracture after two surgical procedures simultaneously.
RESUMO
Background: Multiple treatment protocols have been described in literature for the treatment of terrible triad injury (TTI) of the elbow. We believe that repair of the medial collateral ligament (MCL) should be performed in preference to repair of a small coronoid fracture if the elbow is unstable after fixation/replacement of the radial head and repair of the lateral collateral ligament (LCL). The aim of this study is to report the outcomes of surgical treatment of patients with TTI associated with a small coronoid fracture in whom the coronoid fracture was not addressed. Methods: This study is a retrospective case series of 12 consecutive patients who underwent surgery for acute TTI with a small coronoid fracture (9 Regan-Morrey type I and 3 Regan-Morrey type II). Ten patients had complete MCL injuries. All patients underwent repair of the torn LCL and MCL and treatment of the radial head. The coronoid fracture was not surgically treated. At the final follow-up, the range of motion, degree of flexion contracture, Mayo elbow performance score (MEPS) and Disabilities of the Arm, Shoulder and Hand (DASH) were measured. Results: The mean follow-up period was 13.5 months. At the final follow-up, the mean arc of elbow flexion was 132° and the mean flexion contracture was 10°. The mean arc of forearm rotation was 148°. None of the patients demonstrated elbow instability. The mean MEPS was 92.5 points with seven having excellent results and five having good results. The average DASH score was 11.2 points. Conclusions: Our results showed that good elbow stability, arc of motion and clinical outcomes could be achieved without repair of small coronoid fractures in the treatment of TTI. The repair of MCL injuries should be given priority over the fixation of small coronoid fractures to regain elbow stability. Level of Evidence: Level IV (Therapeutic).

CASE: We describe a patient with incomplete high median nerve palsy after surgical treatment of pediatric supracondylar humeral fracture (SCHF). Preoperative images after 11 months after the surgical treatment of the SCHF showed rotational deformity and an isolated median nerve entrapped between the proximal humerus anteriorly and callus posteriorly in the bony tunnel of the distal humerus. Two years after neurolysis, he showed clinical recovery. Four cases similar to our case were reported previously. CONCLUSION: Common pediatric fractures may cause unusual neuropathy. Rotational deformity of fracture might be an important factor for isolated median nerve entrapment after SCHF.

BACKGROUND: Intra-articular fibromembranous septum in the radiocarpal joint can cause wrist contracture after distal radial fracture, but the mechanism underlying the formation of the septum is unknown. This study examined the clinical outcomes in patients treated with arthroscopic excision of the septum and the factors associated with formation of the septum in patients with and without a septum. METHODS: Fifty-three patients (22 with septum and 31 without septum) treated for intra-articular distal radial fracture with arthroscopy using a volar locking plate and secondary removal of the plate were included. Clinical outcomes and radiological assessments were analyzed. RESULTS: In patients with a septum, the range of wrist flexion and total wrist arc before the second operation were significantly more limited than in those without a septum (p < 0.01 and p = 0.03, respectively). The improvement rate (improvement in wrist arc divided by the wrist arc of the healthy side) after arthroscopic excision of the septum and plate removal was greater in patients with a septum than in those without a septum (6.1% vs. 2.0%, p = 0.08). The significant factors affecting formation of the septum were the residual articular gap and the height of the midradial ridge on computed tomography images. CONCLUSIONS: Intra-articular fibromembranous septum after surgically treated intra-articular distal radial fracture affects limited range of motion and secondary arthroscopic excision of the septum improves the wrist range of motion. Anatomical reduction and maintenance of the articular fragment, as well as anatomical characteristics might be causes of septum formation.

We describe the case of a 44-year-old woman with cerebrotendinous xanthomatosis (CTX) who had a tendon xanthoma on the right olecranon. The patient successfully underwent endoscopic resection. There were no signs of recurrence on MRI 2 years postoperatively. There were no complications related to the surgery, and the patient is completely satisfied with the treatment outcomes. CTX, a genetic metabolic disorder, is associated with the development of tendon xanthomas. Endoscopic resection of tendon xanthoma in the elbow of patients with CTX is a less invasive method than open resection.

Background: Both arterial and venous repair are crucial for optimal results in digital replantation. However, anastomosis of veins becomes challenging in very distal fingertip amputation. This study aimed to report the clinical results of an artery-only replantation without vein repair for a distal fingertip amputation and to analyze the survival rate and clinical outcomes based on the amputation level. Methods: We performed a retrospective review of 47 digits in 38 patients who had undergone fingertip replantation with a mean follow-up period of 12 months. All patients had complete fingertip amputation distal to the lunula. Only one central artery repair distal to the arch was performed. All patients received the postoperative protocol including external bleeding and anticoagulation therapy. Results: By Ishilawa's classification, 12 digits in subzone I, and 35 digits in subzone II. 31 of the 47 fingertip replantations (66%) were successful, and a significantly higher survival rate was observed in subzone I than in subzone II. The mean total active motion of surviving digits was 86% of normal side. The mean grip strength was 82% of normal side. The sensory recovery according to modified Highet and Saunders' classification was S4, S3+, S3, and S2 in fingers 19, 2, 5 and 3, respectively. Conclusions: 66% of survival rate was achieved in fingertip replantation distal to lunula which including large number of crushing/avulsion injury. The result of comparison for the survival rate based on amputation level, a significantly higher survival rate was observed in subzone I compared to subzone II. Therefore, the artery-only fingertip replantation had a better indication for distal amputation, and an aggressive attempt for venous anastomosis or drainage, including a secondary surgery for proximal amputation could be attributed to a higher success rate.

Patients with pediatric trigger thumb present with fixed contracture of the interphalangeal joint (IPJ) or snapping of the thumb. We applied a hand-based dynamic splint using coils at the IPJ. The aim of this study was to report the clinical outcomes of splint therapy versus observation. One hundred twenty-nine thumbs (112 patients and 57 boys) were examined retrospectively. At initial presentation, parents selected the treatment after explanation of pathology and consents were obtained. Treatment was concluded when full extension or resolution of the involved IPJ was achieved; alternatively, surgical treatment was offered for patients who failed to improve. Improvement in extension loss to 0° and hyperextension was defined as resolution of the IPJ. Surgery was not selected as a first-line treatment strategy in any of the cases in this study. The rate of resolution was 59% at 31 months of follow-up in the splint group (99 thumbs) and 43% at 30 months in observation group (30 thumbs); there was no significant difference between the groups (P = 0.15). Twenty-one thumbs showed locking of the IPJ in the extended position during splint therapy, but all recovered with a 71% rate of resolution. The splint group showed a higher rate of resolution than the observation group; however, there was no significant difference between therapies. Our study showed that 55% of patients with pediatric trigger thumb showed resolution following conservative treatment for an average of 30 months until surgery could be performed under local anesthesia. Splint therapy and observation are viable treatment options prior to surgery.

PURPOSE: Replantation of multidigit amputations is difficult to perform due to severe damage to the digits, prolonged operative time, and ischemia. This study aimed to report the clinical results of multidigit replantation. METHODS: A retrospective case series of 34 digits belonging to 12 consecutive patients who underwent multidigit replantation was conducted. Patients with injury in at least one or more amputated fingers proximal to the insertion of the flexor digitorum superficialis tendon were included. The mean follow-up duration was 18.1 months. The number of amputated digits, mechanism and zone of injury, survival rate, and clinical outcomes, including the range of motion, grip strength, and sensory recovery, at the final follow-up were reviewed and analyzed. RESULTS: The mean number of amputated digits per patient was 2.8. Complete survival was achieved in 27 of 31 digits (87.1%). The mean final percentage of total active motion of injured digits was 47.0%, and the mean percentage of grip strength was 45.9% of the contralateral uninjured side. The comparison between patients with two and three amputated digits showed that there was no significant difference in both survival rates and functional outcomes. CONCLUSIONS: The results showed that both the survival rates and functional outcomes of multidigit replantation were as good as those of single-digit replantation, and there was no significant difference for outcomes between patients with two and three amputated digits. These results suggested that all multidigit replantations should be performed regardless of the number of injured digits or amputation zones.

Intra-articular osteoid osteoma (OO) of the elbow is rare. We report a 26-year-old man who presented with pain, swelling, and limited elbow range of motion. Plain computed tomography (CT) showed a radiolucent round lesion at the distal humerus and reactive bone in the olecranon fossa. Conservative treatment with salicylate failed under the suspicion of OO. During elbow arthroscopy, a red solitary lesion was noted after resection of the white reactive bone in the olecranon fossa and was excised en bloc using a bony chisel. Histological examination showed OO. The patient's symptoms resolved the day after surgery. The patient remained asymptomatic 2 years postoperatively. This case report shows the successful clinical results of an arthroscopic procedure for intra-articular OO based on two primary goals: precise location of the lesion indicated by reactive bone on preoperative CT and histological verification using bony chisel.
