“…After duplicates were consolidated and articles screened for relevancy, 30 articles comprising 34 patients met inclusion criteria and were included in the analysis (Supplementary Table 1). 3,5-35 Studies comprised of case series and reports dating from 1953 to 2019. Each study included 1 to 4 patients, 31 of which described 1 patient.…”

Background: Lipomas are a rare cause of posterior interosseous nerve (PIN) compression. A systematic review of predictors for motor recovery has not been performed. This study sought to evaluate whether patient or lipoma characteristics are associated with motor recovery and could be used to determine when immediate tendon transfers at the time of excision should be performed. Methods: Articles describing patients with forearm lipomas resulting in PIN compression with motor weakness were included. Patient age, gender, symptom duration, laterality and largest dimension of lipoma, surgical intervention, and motor recovery were identified. Article quality was assessed via the Methodological Index for Non-Randomized Studies criteria. Results: Thirty articles reporting on 34 patients were identified. Average age was 58.2 years. Average largest lipoma dimension was 5.7 cm. All patients underwent lipoma removal, and 2 had concomitant tendon transfers. In all, 73.5% of patients had complete motor recovery at an average of 9.7 months. Patient age and largest dimension of lipoma, and duration of symptoms were not significant predictors of motor recovery. Symptom duration was a significant predictor of motor recovery in binary regression, particularly if < 18 months. Conclusions: The majority of patients with PIN weakness secondary to lipoma are likely to have complete motor recovery after excision alone. Concomitant tendon transfers should be considered for patients symptomatic for greater than 18 months. Further, adequately powered, studies are required to stratify risk factors and evaluate other modalities to identify the minority of patients who would benefit from immediate tendon transfer.

“…They have been described in literature. Avram and Hynes [1] in 2004 described 29 cases in literature which have been reported in past 10 years [2,3]. The neuropathies of PIN can be due to rheumatoid synovial cysts [4], ganglion [5], myxoma [6], pseudogout [7] and chondroma [8] among others.…”

Posterior interosseous nerve compressions are rare. The compression of the posterior interosseous nerve can happen either before, or through or after the course of the nerve in the supinator muscle. Tumors could rarely lead to secondary compression of the nerve by mass effect. We describe a case of a lady aged 73 years with a posterior interosseous nerve syndrome due to an intermuscular lipoma. The patient had appreciable recovery after surgery and physiotherapy. Keywords: Intermuscular lipoma, Posterior interosseous nerve, Compression.

“…Several additional cases have been reported in the last 10 years. 2,[5][6][7]9,14,22 Typi-cally, after resection of lipomas, PIN recovery is anticipated. 1 We present 2 patients in whom the compression led to near discontinuity of the nerve; given the severity of the lesion, spontaneous recovery would not be anticipated and tendon transfers were offered early.…”

Paralysis of the posterior interosseous nerve (PIN) secondary to compression is a rare clinical condition. Entrapment neuropathy may occur at fibrous bands at the proximal, middle, or distal edge of the supinator. Tumors are a relatively rare but well-known potential cause. The authors present 2 cases of PIN lesions in which compression by a benign lipoma at the level of the elbow resulted in near transection (discontinuity) of the nerve. They hypothesize a mechanism-a "sandwich effect"-by which compression was produced from below by the mass and from above by a fibrous band in the supinator muscle (i.e., the leading edge of the proximal supinator muscle [arcade of Fröhse] in one patient and the distal edge of the supinator muscle in the other). A Grade V Sunderland nerve lesion resulted from the advanced, chronic compression. The authors are unaware of a similar case with such an advanced pathoanatomical finding.
