The Ascension PyroCarbon prosthesis has been used in proximal interphalangeal joint osteoarthritis. The dimensions of the intramedullary distal metadiaphyseal canal (isthmus) of the proximal phalanx and the base of the middle phalanx of cadaver fingers were investigated radiographically ( n = 304) and macroscopically ( n = 152). In up to 30% of the phalanges, the isthmus was smaller than the stem of the smallest proximal component size. The distal component head was always smaller than the middle phalanx base. Insertion and success of the Ascension PyroCarbon prosthesis is strongly dependent on bone morphology. A critical examination of the isthmus in radiographs is recommended in planning. If the isthmus is clearly smaller than the smallest proximal component, insertion of the prosthesis could be inadvisable. A clear mismatch between the distal component and the middle phalanx base should be avoided due to the potential risk for late subsidence and failure of the prosthesis.

Five patients were successfully treated with a modified “on-top-plasty” technique, in which a finger stump is lengthened by transfer of an adjacent amputation stump with a reverse blood flow fingerstump. This technique can be performed in the acute phase or as a secondary procedure. A conventional on-top-plasty can be performed by transfer of a partially amputated index or ring finger to the “top” of the proximal phalanx of an amputated middle finger. Alternatively, the transferred part may be used in an intercalated fashion to reconstruct the middle phalanx, using a prosthesis to reconstruct the proximal interphalangeal joint. The results, complications and disadvantages of the technique are reported. We propose this procedure for the reconstruction of the middle ring finger when a free microneurovascular toe-to-hand transfer is contraindicated or refused by the patient.

The morphology of the proximal interphalangeal joint was determined using a photographic technique. The head of the proximal phalanx, viewed end on, has a complex trapezoid appearance characteristic for each named digit. The asymmetric condyles diverge from one another and are separated by an intercondylar groove that increases in depth from the dorsal to the palmar surface. Saggital sections of the head of the proximal phalanx are not circular, but, sections taken in the plane of maximum dimensions of the condyle are circular with a radius of curvature of approximately one half of the height of the condyles. The articular surface of the base of the middle phalanx is not circular in outline in either the saggital or coronal plane. In coronal sections the articular surface is biconcave convex with a prominent median ridge separating the two adjacent concave articular surfaces. The implications of this varied morphology on implant design are discussed.

Many different surgical techniques have been used to treat unstable dorsal proximal interphalangeal joint fracture-dislocations. The authors have used the base of the middle phalanx of the second toe base as an alternative autograft to treat this type of injury. This retrospective study assessed the clinical outcomes of this procedure in 11 patients. Range of motion, grip strength, Disability of the Arm, Shoulder and Hand score and donor site morbidity were assessed at regular intervals postoperatively. Nine patients had acute injuries and two had chronic injuries. The mean range of motion in the proximal interphalangeal joint at final review was 65° for patients with acute injuries and 41° for patients with chronic injuries. Other outcomes were satisfactory and there were no complications. Level of evidence: IV

Several surgical options have been described to manage persistent dorsiflexion contracture at the metatarsophalangeal joint and plantarflexion contracture at the proximal interphalangeal joint of the fifth toe. We describe a minimally invasive technique for the management of this deformity. We perform a plantar closing wedge osteotomy of the 5th toe at the base of its proximal phalanx associated with a lateral condylectomy of the head of the proximal phalanx and at the base of the middle phalanx. Lastly, a complete tenotomy of the deep and superficial flexor tendons and of the tendon of the extensor digitorum longus is undertaken. Correction of cock-up fifth toe deformity is achieved using a minimally invasive approach.

The anatomy and histology of the volar plate at the proximal interphalangeal joint and the mechanism of fracture/subluxation of the base of the middle phalanx in closed proximal interphalangeal joint injuries is reviewed. Our current technique of repair for these injuries and its evolution from Eaton’s original procedure is described. The results of 71 cases of volar plate arthroplasty performed over a five-year period for fracture/subluxations of the proximal interphalangeal joints are presented with follow-up ranging from six months to four years. 62 (87%) patients achieved a stable pain-free joint with a range of motion from 5° to 95° within two months. Complications were uncommon and correctable with an overall eventual patient satisfaction rate of 94%.

The primary aim of this study was to assess the clinical and radiological results after hemi-hamate resurfacing arthroplasty in patients with acute or chronic unstable fractures of the base of the middle phalanx and to describe technical features that can facilitate the surgical procedure. Hemi-hamate arthroplasties were done in 19 patients (mean age 39 years) with an isolated fracture at the base of the middle phalanx that involved more than 40% of the articular surface. We assessed ten chronic cases (treated >6 weeks after fracture) and nine acute ones (<6 weeks) at a mean of 24 months. Pain scores, QuickDASH scores, grip strengths, range of motion and radiological findings were recorded at follow-up. At follow-up, the mean active flexion at the proximal interphalangeal joint was to 83° with a mean fixed flexion of 17° (active range of motion 66°). The mean active distal interphalangeal motion was 41°. The mean visual analogue scale score was 1.1. The mean QuickDASH score was 11. The mean pinch strength was 82% of the opposite side. Radiographs revealed one partial graft lysis. Level of evidence: IV

Extensor Lag

Current approaches to the proximal interphalangeal (PIP) joint have potential complications and limitations. We present a dorsal approach that involves splitting the extensor tendon in the midline, detaching the insertion of the central slip and repairing the extensor tendon without reinserting the tendon into the base of the middle phalanx. A retrospective review of 16 digits that had the approach for a PIP joint arthroplasty with a mean follow up of 23 months found a postoperative PIP active ROM of 61° (range 25–90°). Fourteen digits had no extensor lag, while two digits had an extensor lag of 20° and 25°. This modified approach is fast and simple and does not cause an extensor lag.
