The study assessed whether a relationship existed between the lengths of the phalanges of the fingers of the hand. The centres of rotation of the joints in each finger were determined by dissection of cadaveric hands. Using these data, the distances between the joint centres was determined on anteroposterior hand X-rays taken for clinical purposes. The study has shown that, for all the fingers, there is a ratio of1 for the distance between the metacarpophalangeal and proximal interphalangeal joint and the distance between the proximal interphalangeal joint and the finger tip. The ratio for the distances between the interphalangeal joints and the distal joint and the tip approximates to 1.3 for the index, middle and ring fingers and to 1.0 for the little finger. No evidence was found to support Littler’s hypothesis that the interarticular distances of the finger follow the Fibonacci sequence.

Objective To evaluate the efficacy of a novel dynamic distraction external fixator for proximal interphalangeal joint (PIPJ) fracture-dislocation. Methods From March 2005 to March 2014, 20 patients with PIPJ fracture-dislocation were treated with our technique. Function scores according to the Michigan Hand Outcome Questionnaire (MHQ) score, union time, grip strength, and range of motion (ROM) were recorded before and after treatment. Results All patients completed a mean follow-up of 22 months (range, 12–60 months). All patients achieved fracture union and joint reduction. The mean union time was 3 months (range, 2–6 months). The mean postoperative MHQ score was 88.00 ± 3.42 (range, 84.00–92.00). Postoperative grip strength of the affected sides was 92% of the contralateral sides. X-rays showed that the fracture line disappeared completely with a good joint contour. The range of extension in the PIPJ was −5° (range, −10°–0°). The range of flexion in the PIPJ was 89.40° ± 9.79° (range, 75°–100°). Postoperatively, four patients had slight narrowing of the joint space and two had an uneven articular surface. Pin breakage, loosening, and tract infection were not observed. Conclusions The novel dynamic distraction external fixator is a promising option for PIPJ fracture-dislocation.

We present a case of chronic post-traumatic hyperextension of the PIP joint of the little finger. The volar plate was reattached at the original attachment site of the proximal phalanx using two suture anchors and tenodesis of the radial half slip of the FDS tendon was added. An acceptable result was obtained.

Experience Difficulty

Abstract Patients suffering from medical conditions resulting in hand impairment experience difficulty in performing simple daily tasks, like getting dressed or using a pencil, resulting in a poorer quality of life. Rehabilitation attempts to help such individuals regain a sense of control and normalcy. In this context, recent advances in robotics have manifested in multiple designs of hand exoskeletons and exosuit gloves for assistance and rehabilitation. These designs are typically actuated using pneumatic, shape memory alloys and motor-tendon actuators. The proposed Motor Tendon Actuated Exosuit Glove (MTAEG) with an open palm is a soft material glove capable of both flexion and extension of all four fingers of the human hand. Its minimally invasive design maintains an open palm to facilitate haptic and tactile interaction with the environment. The MTAEG achieves flexion-extension motion with joint angles of 45° at the metacarpal joint which is 57% of the desired motion; 90° at the proximal interphalangeal joint which is 100% of the desired motion; and 50° at the distal interphalangeal joint which is 96% of the desired motion. The paper discusses the challenges in achieving the desired motion without the ability to directly model human tendons, and the inability to actuate joints individually.

A 59-year-old man suffered from subcutaneous rupture of the flexor tendon of the little finger associated with fracture of the hook of hamate. He could not flex his little finger completely at the distal interphalangeal joint, but incomplete flexion of the proximal interphalangeal joint was possible. Surgical exploration revealed anomaly of the flexor digitorum superficialis of the little finger, as it originated from the palmar aspect of the carpal ligament, and a small portion of the muscle belly was traversed toward the A1 pulley over the profundus tendon and then it ran into the A1 pulley as a normal superficialis tendon. The flexor digitorum superficialis of the little finger is well known to show variations, but our case is extremely rare, and furthermore there are no reports in the available literatures about the function of this anomalous muscle.

After the medial femoral condyle (MFC), the phalanges are the second most common site for osseous cyst-like lesions (OCLLs). Conservative treatment of phalangeal cysts on the convex surface of proximal phalanx presents a technical problem with access to the stoma of the cyst. Surgical therapy options usually aim to avoid cyst enlargement through drilling or screw placement or to encourage lesion filling with osteoconductive material. This paper describes a case of treatment of the OCLL in a yearling Czech warmblood filly with surgical arthrodesis, together with the packing of the OCLL with calcium phosphate biocement (CPB). The filly showed a chronic, moderate to severe, intermittent left hindlimb lameness. Dynamic examination combined with regional anesthesia and radiography confirmed a clinically significant large OCLL on the distal joint surface of the first phalanx. Treatment of the OCLL was performed by surgical arthrodesis of the proximal interphalangeal joint, using two paraxial and one axial crossed lag screw, after curetting of the cyst and filling with CPB.

Camptodactyly is a condition where there is a permanent flexion contracture at the proximal interphalangeal joint mostly involving the little finger. This condition has a varied presentation and hence treatment is controversial, whether conservative management or surgical correction. Here, we present two cases of camptodactyly that were managed with surgery.
