Sarcoidosis of the phalanx is rare and is usually associated with severe systemic disease. We present a patient with recurrent phalangeal sarcoidosis and new evidence of a changing radiological pattern. The clinical presentation and outcome is discussed. High dose steroid treatment and careful long-term follow-up is recommended.

Giant cell tumour of bone in the phalanx of the hand is extremely rare. A case of giant cell tumour of distal phalanx treated with a ray amputation is presented.

Hand tumors are not common and a swollen finger poses considerable diagnostic dilemma. We present a case of a middle-aged farmer who had presented with a painless swelling of the middle finger of the right hand without any neurovascular deficit or evidence of metastasis. An X-ray of the finger showed cortical expansion and bony erosion of the proximal phalanx. A fine needle aspiration cytological examination was inconclusive. He underwent a digit amputation in view of subsequent morbidity and chances of recurrence following local excision. Biopsy proved it to be a giant cell tumor of the proximal phalanx. Following six months of treatment he is doing well. We herein highlight an unusual tumor of the finger and its diagnostic and treatment challenges.

We present a case of phalangeal deformity in a 17-year-old boy. The deformity was caused by a neurofibroma associated with neurofibromatosis type 1, affecting the left ring finger. The mass was surgically resected. Recurrence had not occurred at three-year follow-up.

Intraosseous epidermoid cyst is considered a rare benign inclusion cyst found mainly in the skull and phalanges. Once the cyst is differentiated from other similar lesions, the cyst can be treated with simple curettage, seldom requiring additional managements. We experienced this rare case that had been treated successfully without complication.

We report of a pathological fracture of the middle phalanx of the little finger due to periosteal chondroma. The periosteal chondroma occupied an extensive area of the middle phalanx extending to the proximal interphalangeal joint, and the fracture involved the distal interphalangeal articular surface. The fracture was internally fixed using a strut bone grafting after resection of the chondroma. One year and four months after the operation, remodeling of the phalanx had completed without recurrence and functional loss.

Avulsions of the flexor digitorum profundus (FDP) tendon and phalanx fractures are both common injuries for rugby players, but these concurrent injuries in the same finger have not been previously described. This case describes a 20-year-old female rugby player who sustained a right ring finger comminuted, mildly displaced middle phalanx fracture. The patient was evaluated by a hand surgeon 3 weeks after the injury, and non-operative management with a splint was elected. One week later, upon further examination, the patient demonstrated persistent inability to flex the distal interphalangeal joint (DIPJ) of the ring finger. Ultrasound was inconclusive but an MRI demonstrated avulsion of the FDP tendon from the distal phalanx, consistent with a jersey finger injury. The patient subsequently underwent open repair of the FDP tendon. This case illustrates the importance of careful physical exam and index of suspicion for coexisting injuries.

Paediatric hand fracture care presents unique considerations and challenges. The proximal phalanx is the most injured location. This review details pearls for the examination of the injured paediatric hand, immobilisation considerations and treatment strategies. Over-treatment can lead to unnecessary stiffness, missed activities, increased healthcare costs or unnecessary surgical morbidity. Undertreatment can promote malunion and dysfunction. Fracture patterns discussed include those of the phalangeal head, neck, shaft and base. The concepts covered will help optimise the evaluation and treatment of children with injured proximal phalanges.

Level of Evidence: Level V (Therapeutic)

Background: Most unstable hand fractures in children are treated by closed methods. If osteosynthesis is required, Kirschner (K)-wires are commonly used, though they carry a risk of injury to the physis. We have been using a mini external fixator system (MEFS) for the treatment of unstable periphyseal fractures of the hand. The aim of this study is to describe the application and report the outcomes of MEFS for the treatment of periphyseal fractures of the hand.

Methods: We retrospectively reviewed all the patients with periphyseal fracture of the hand treated with MEFS from March 2010 to December 2019. Data with regard to age, sex, hand dominance, digit and bone injured, mechanism of injury, medical records and related radiographs were collected. Salter–Harris classification was used to classify epiphyseal fractures and the Al-Qattan classification for categorising neck fractures. Range of motion and residual deformity of the affected fingers were evaluated during follow-up and at 3 months postoperatively.

Results: Fourteen periphyseal unstable fractures were treated using closed reduction and MEFS. Only one patient with a fracture of the neck of the proximal phalanx of the little finger required revision surgery. No patient had pin site infection or pin loosening and the device was well tolerated by all patients. All fractures united and all the patients recovered a full range of motion at final follow-up.

Conclusions: The MEFS is a reasonable alternative for unstable periphyseal fractures with good outcomes and avoids the risk of iatrogenic physeal injury from K-wire fixation.

Level of Evidence: Level IV (Therapeutic)

Background: To compare the observed healthcare and societal costs of intramedullary screw (IMS) and plate fixation of extra-articular metacarpal and phalangeal fractures in a contemporary Australian context.

Methods: A retrospective analysis, based on previously published data, was performed utilising information from Australian public and private hospitals, the Medicare Benefits Schedule (MBS) and the Australian Bureau of Statistics.

Results: Plate fixation demonstrated longer surgical lengths (32 minutes, compared to 25 minutes), greater hardware costs (AUD 1,088 vs. AUD 355), more extended follow-up requirements (6.3 months, compared to 5 months) and higher rates of subsequent hardware removal (24% compared to 4.6%), resulting in an increased healthcare expenditure of AUD 1,519.41 in the public system, and AUD 1,698.59 in the private sector. Wage losses were estimated at AUD 15,515.78 when the fracture cohort is fixed by a plate, and AUD 13,542.43 when using an IMS – a differential of AUD 1,973.35.

Conclusions: There is a substantial saving to both the health system and the patient when using IMS fixation over dorsal plating for the fixation of extra-articular metacarpal and phalangeal fractures.
