(1) Introduction: Tendinous mallet finger is a frequent deformity that occurs after an extensor tendon injury during sports or daily life activities. Despite the existence of numerous non-operative and operative techniques to address this deformity, there is a controversy on its optimal management. In this study, we aimed to present a direct tendon suture technique using the distal interphalangeal (DIP) joint open approach for treating tendinous mallet finger injury. (2) Methods: Between 2019 and 2021, 19 patients with closed non-fracture tendinous mallet fingers underwent the direct tendon and paratenon repair technique. After skin incision, we opened the paratenon with lazy S shape incision and found the ruptured proximal and distal tendon ends. We reapproximated the tendons using a simple interrupted suture with Prolene #6/0. After that, we meticulously performed paratenon repair using PDS #6/0 for preventing readherence. Temporary trans-articular Kirschner wire fixation was used for 4 weeks. (3) Results: All patients were followed-up for 3-8 months (mean: 4.8 months). The mean final extension lag was 6.5 degrees, and the overall rate of cases with excellent and good outcomes using Crawford\'s criteria was 85%. (4) Conclusions: In conclusion, this surgical approach could be a reliable alternative for the treatment of tendinous mallet finger injuries.

BACKGROUND: While suture anchors are widely used in medical procedures for their advantages, they can sometimes lead to complications, including anchor prolapse. This article presents a unique case of suture anchor prolapse at the base of the distal phalanx of the little finger after extensor tendon rupture reconstruction surgery.
METHODS: A 35-year-old male, underwent extensor tendon rupture reconstruction using a non-absorbable suture anchor. After seven years the patient visited our outpatients complaining of stiffness, pain, and protrusion at the surgical site. Initial X-ray imaging suggested suggesting either a fracture of the distal phalanx or tendon adhesion but lacked a definitive diagnosis. Subsequent magnetic resonance imaging (MRI) revealed bone connectivity between the middle and distal phalanges with irregular signal shadow and unclear boundaries while maintaining a regular finger shape. MRI proved superior in diagnosing prolapsed suture anchors, marking the first reported case of its kind. Surgical intervention confirmed MRI findings.
CONCLUSIONS: Suture anchor complications, such as prolapse, are a concern in medical practice. This case underscores the significance of MRI for accurate diagnosis and the importance of tailored surgical management in addressing this uncommon complication.

UNASSIGNED: Chronic terminal extensor tendon injury produces mallet deformity and secondary swan neck deformity. It can be found in neglect cases and in a failed cases after conservative treatment or primary surgical repair. Surgery is considered in cases with extensor lag of more than 30° and functional deficit. Reconstruction of the spiral oblique retinacular ligament (SORL) has been reported in literatures to correct swan neck deformity by a dynamic mechanical basis.
METHODS: Three cases of chronic mallet finger associated with swan neck deformity were treated by the modified technique of SORL reconstruction. Range of motion (ROM) of distal interphalangeal (DIP) joints and proximal interphalangeal (PIP) joints were measured along with the complications. The clinical outcome was reported using the Crawford\'s criteria.
UNASSIGNED: All patients had an average age of 34 years (20-54). Average time to surgery was 16.67 months (2-24) and average of DIP extension lag was 66.67°. All patient gave excellent Crawford criteria at the latest follow up (average 15.3 months). The average PIP joint ROM were -1.60 (00 to -50) of extension and 1100 (1000-1200) of flexion for the PIP joint and -1.60 (00 to -50) of extension and 83.330 (800-850) of flexion for the DIP joint.
CONCLUSIONS: We present our technique to manage chronic mallet injury which only utilized two skin incisions and one button at the distal phalanx to minimize risk of skin necrosis and patient discomfort. This procedure can be considered as one of the options for the treatment of chronic mallet finger deformity associated with swan neck deformity.

UNASSIGNED: A nail bed injury concomitant with an underlying physeal injury of the distal phalanx is termed as \"Seymour\'s fracture.\" These are seemingly innocuous injuries commonly misdiagnosed and are subsequently under-treated. These injuries demand treatment like an open fracture to prevent complications such as infection, growth arrest, and nail dystrophies.
UNASSIGNED: A 13-year-old boy suffered Seymour\'s fracture of the left ring finger distal phalanx after a direct injury from a dodge ball. The fracture was treated with thorough debridement with normal saline, physeal injury reduction through the wound, and fixation with k-wire passed through the tip of the ring finger, metaphysic, physis, and the tip of the k-wire ending in the epiphysis of the distal phalanx. The nail bed was sutured with 3-0 monofilament absorbable sutures. The fracture healed at 3 months and a 1-year follow-up showed a completely formed nail without any deformity.
UNASSIGNED: Excellent outcome was observed with debridement of the wound, nail bed repair, and fixation with k-wire in our case. Nail bed injuries in children should be treated with a high index of suspicion for Seymour\'s fracture as it necessitates treatment like that of an open fracture to avoid complications.

Swan neck deformity (SND) can be the manifestation of an acute trauma. We present a case report of a young basketball player with an acute traumatic SND determined by the single ulnar oblique retinacular ligament rupture. The patient caught a ball directly upon the tip of his right\'s hand middle finger into extension. He immediately presented a SND with impossibility to actively flex the proximal interphalangeal joint (PIPJ), while preserving active flexion and extension of the distal interphalangeal joint (DIPJ). Hyperextension of PIPJ was reducible with passive mobilization, thus allowing full passive range of motion. The SND was seen to be caused by the lesion of the ulnar oblique retinacular ligament (ORL) on its distal insertion, with consequent dorsomedial migration of the ulnar lateral band. The early surgical distal reinsertion of the ORL allowed the restoration of the original kinematics of the finger flexion-extension.

BACKGROUND: Close reduction by extension-block K-wire fixation for acute mallet fracture is based on two sound orthopedic principles - stable arc splinting and early protected motion. Distal interphalangeal joint splinting is still the technique commonly used for mallet fractures with significant morbidity and only moderate functional outcome.
METHODS: We have demonstrated here Ishiguro\'s technique in a partially treated 2 weeks old mallet fracture with the flexion deformity at distal interphalangeal (DIP) joint after proper preoperative assessment. Peroperatively, proper anatomical localization of mallet fragment was done under fluoroscopy. Reduction of the avulsion fracture was done by extension block K-wire and intra-articular K-wire was inserted subsequently to hold the reduction in place and DIP joint in extension. Later on K-wires were removed at the end of 6 weeks follow up. Patient was subjected to the physiotherapy during the course of the treatment. Excellent functional outcome was noted at the end of three months.
CONCLUSIONS: Closed Extension block pinning can give acceptable functional outcome even in delayed mallet finger injuries. Full range of movement at the affected joint is an important pre-requisite for the same.

BACKGROUND: Mallet finger injuries are usually successfully treated non-operatively with a splint. Most patients are reviewed at least twice in a clinic after the initial presentation in A&E. A new protocol promoting \"self-care\" was introduced at our institution. Patients were provided with structured verbal and written information, and given access to a telephone helpline.
METHODS: A prospective electronic patient record was used to identify all patients who presented to the emergency department with a mallet finger with a minimum six month follow-up. A satisfaction and patient reported outcome measure was administered via a postal questionnaire. The response rate was 36/47 (77%).
RESULTS: The median QuickDASH score was 2.3 (IQR 0 to 4.6). All patients were satisfied with the treatment plan provided. Nine used the helpline and all were satisfied with information given. Although 13 patients reported some extensor lag, or bump, they had no functional limitation. Seven patients were reviewed by the general practitioner or other clinicians during their treatment period for issues such a skin care, splint size changes or sickness certification. Five were subsequently reviewed at the end of their treatment period in a clinic at their request, or their general practitioner, but did not require further surgical intervention.
CONCLUSIONS: Self-care for mallet finger injuries, with adequate patient information and telephone back-up, leads to acceptable functional results and satisfaction.
